Message from the Special Guest

It gives me immense pleasure to know that BES and BAEC are jointly organizing a Conference on Electronics and ICT which will be held at AECD auditorium on 25-26 November, 2018. I am also delighted to find the very timely and appropriate theme of the conference "A milestone towards Digital Bangladesh: Bangabandhu Satellite I”. Bangabandhu Satellite I is a stepping stone for Bangladesh in the digital era. With the successful launch and positioning in orbit, this is a formal journey towards the space-age for Bangladesh which became independent only 47 years back. Our father of the Nation Bangabandhu Sheikh Mujibur Rahman dreamt of a dignified Bangladesh before the world community while he believed that unless communication with the outside world is not properly maintained, it would not be possible to advance the country. From the launching of the satellite, Bangladesh will be benefitted from not only entertainment, also in education, medicare and gathering information about natural disaster.

The Conference on Electronics and ICT covers emerging topics. There are a number of delegates and invitees who will deliver state of the art keynote addresses.The two-day event would be a feast and delight for researchers.The conference will provide an excellent platform for developing newideas and technologies.

I am confident that every delegate will learn something new and will get inspiration to excel. I personally as well as on behalf of Bangladesh Computer Society and Internet Society Bangladesh Chapter wish the organizers very success.

I am confident that this joint conference will come up with important recommendations which will eventually help our country to materialize the goals of Digital Bangladesh.

Hasan Babu) President, Bangladesh Computer Society (BCS) Chair, Internet Society, Bangladesh Chapter (ISOC) Pro-Vice-Chancellor, National University, Gazipur, Bangladesh Professor and Former Chairman, Department of Computer Science & Engineering University of Dhaka, Bangladesh Professor and Founding Chairman, Department of Robotics and Mechatronics Engineering University of Dhaka, Bangladesh E-mail: [email protected]

Abstract: In the 21st Century, with the rapid advancement of Information and Communication Technology (ICT), the adaptation of the same has become a vital integral component of education and more specifically in the learning experience of learners across the globe. Technology is of increasing importance in our everyday lives and that presence will most certainly increase in the coming years with new innovations. In the passage of this digital life, whether looking up a book on a computerized card catalogue at the public library, making a withdrawal from an automated teller machine, or accessing telephone messages, everyday activities have been transformed by digital services. In this growing digital passage to follow, the notion of a literate populace must be expanded to include the technology-based skills and abilities that will enable citizens to function in an increasingly technological world utilizing digital services efficiently. Education is a pivotal aspect for the human development and the governance in education for digital drives today demand changes to accommodate desired transformations in teaching and learning at all levels using ICT which can help to focus on performance in education service delivery, and in turn, contribute significantly in capacity building with a basis upon which to raise performance in human development. In this keynote, digital readiness and role of academia in achieving the readiness is discussed from the perspectives of Digital Transformation.

Digital Readiness Pew Research Center (http://www.pewinternet.org) in one of their comprehensive studies on Digital Readiness through focused survey findings elaborated on the factors associated with the measurement of digital readiness. The study identified preparedness of end users in the form of digital skills, their trust in the digital technology which may influence the use of digital tools known to be “Digital Readiness”. The first dimension of Digital readiness, Digital skills contribute the necessary skills to initiate online sessions with need based surfing and content sharing. The second dimension, Trust resulted from the beliefs about the capacity to determine the trustworthiness of information online safeguarding personal information. Figure 1. Digital Readiness Gap [source: The third dimension, originated from the other two Pew Research Center] dimensions, Use represents the degree to which using digital tools to carry out online tasks.

As seen from the above Figure 1, about 57% of adults have little or no awareness of common core standards adopted in the year 2010 by the federal government in US. The curricula created by states 29

International Conference on Electronics and ICT - 2018, 25-26 November, 2018 are based on these common core standards. The other distributions seen form the findings of the survey seems not very encouraging considering the year 2015.

Despite the challenges of achieving higher digital readiness in US, in the rapid emergence of Digital Bangladesh with a huge momentum of digital inclusion of citizen centric services, digital readiness of Digital Bangladesh is of utmost importance and all educational institutions along with the universities have major role to play in achieving desired readiness. Besides, the digital transformation guideline published by WITSA in the year 2017 also fosters the needs for digital readiness. In this article, based on the present practices, thoughts will be shared for inclusive digital readiness along with some recommendations.

Digital Transformation and Digital Readiness Digital transformation today is an integral part of the business development worldwide. World Information Technology and Services Alliance (WITSA) proposed on “Digital Transformation: Enabling Principle Recommendations for Digital Transformation” on January 2017. As per the recommendations by WITSA, digital transformation is not well formalized and understood yet form the point of view of value creation. Since digital technology is triggering the changes in our society in an appreciable way on continuous basis. As a result, digital transformation affects neatly every aspect of business and government operations encompassing the digital life. Even software development is being digitally transformed and taking seamless integrations. This digital transformation intends to develop or enhance trust, security and privacy challenges.

Digital business process management is an outcome of the digital transformation of business. Digital readiness is connected to digital business process management. The emergence of digital business Figure 2. Digital Priority Challenges [source: McKinsey, technologies enhances the digital readiness of the 2016] organization. Digital business processes manage business processes interactivity for participatory data sharing and financial relationships. Most obviously, digital transformation is one of the challenges an enterprise can undertake to ensure digital readiness. Based on number of partners may it be internal, external, or both, involved in any given business process, a system in which a multitude of electronic parties can securely communicate, collaborate, and transact without human intervention is highly agile and efficient. This digital business cohesion brings productivity and efficiency in the business.

Digital Transformation for Readiness in Education Digital transformation of education is badly a necessity for readines in line with the core underlying principles of Digital Bangladesh is most challenging and demands strategic planning to achieve the desired goal. The following figure is an expected form of transformation layout.

International Conference on Electronics and ICT - 2018, 25-26 November, 2018

As seen in the Figure 3, the whole framework is centered around Student being at the core evolving around Leadership, Supporting High Quality Teaching, Involvement and Expectation components. Student is continuously evolving from past achievements to future aspirations based on personalized learning environment. The leadership component comprises communities of learning integrated with SMS system and intra-school networks for schools operating in the clouds. Supporting high quality teaching component requires integrated digital learning environments comprises of blending of media and learning repositories with open learning standards. Besides digital assessment tools to be integrated with the expected learning outcome of digital repositories to support high quality teaching is most crucial. This provides continuous improvement in the teaching and learning process. In order to strengthen the inclusion, involvement component demands integration of parents into the process of learning through parents website, parents portal and data dashboard etc. The final component of the framework is based on expectation for improving student centered pathways Figure 3: Digital Transformation to ensure career planning and further demands for the Framework [source: Internet] higher education.

In most cases, applications and practices based on the above framework vary widely and are customized to suit the different needs and knowledge of individuals and organizations based on contextual settings across the globe. There are felt need of standard or straightforward framework to scaffold blended learning to suit a range of needs and subjects. The common use of digital transformation is the provision of supplementary resources for traditional courses using an institutional virtual learning environment such as Moodle and other LMS (Learning Management System) and LFS (Learning Feedback System) which is integrated in the cloud.

Digital Readiness through Academia: Present Context The digitalization effort is all around the academia in Bangladesh which is triggered primarily due to Digital Bangladesh drive. Schools and colleges along with the all higher educational institutes are transforming through active engagement with digital repository. Despite common standards, the drive is very encouraging. All public and private universities are using digital services for their students starting from admission to registration of courses till issuance of academic transcripts. The University Grants Commission, Bangladesh (UGC) through Higher Education Quality Enhancement Project (HEQEP) of World Bank driving the quality aspects through state of the art research facilities creation at different universities along with the strengthening research network through Bangladesh Research Education Network (BDREN) at UGC. BDREN already providing virtual conferencing system in more than 30 public universities and in the expansion phase another 20 more popup points for the connectivity to the research and education network. In the academia, virtual classroom is used by the students for blended learning opportunities and teachers are posting class discussion, example and exercise materials on this platform. Some of the popular virtual platform in use are Google classroom, Moodle, Piazza, Eliademy and other free learning management system. The teaching and learning, despite the use of information technology, is still more traditional. The students are also using forum, creating blogs and writing wikis along with the massive use of social media.

Digital Readiness through Academia: Expected Despite the utilization of the information technology and Internet in all aspects of education, the readiness deserves strategic developments based on the following recommendations:

International Conference on Electronics and ICT - 2018, 25-26 November, 2018

a. Develop massive open online courses (MOOC) for all levels starting from school till university both in Bangla and English b. Develop interactive learning content based on blending learning techniques for important and emerging technology c. Develop unified outcome based ICT pedagogy for all levels of education d. Develop virtual platform for online collaboration of teachers at all levels e. Develop one stop digital readiness repository for students and teachers f. Develop unified and outcome based curricula for all universities for important disciplines

Given the benefits to be gained from digital transformation for readiness, the key challenges are transformation based on contextual which vary across different countries. The time and complexity of designing and development of a teaching and learning repository are key factors as well as lack of internal expertise and cost along with the attitude of learners to solutions. Besides, the challenge lies with the time for training, and to re-design and administer the course unit and getting the students on board with the new format of learning.

Conclusion Digital readiness through education transformation, though challenging, can only help transforming learning for 21st century education for effective education governance which offers a unique opportunity to fully integrate pedagogy and technology with teaching and learning.

The polarization detection of the received signal for many applications such as polarimetric sensors, MIMO, satellite remote sensing, ITS, radars etc. is becoming very essential in recent years. In this paper, a slot-ring array antenna for linear polarization detection is proposed. The array antenna consists of four slot-ring antenna elements. Each slot-ring element is configured to detect either ±45° or 0° and 90° linearly polarized signal at two different frequencies; 5 GHz and 10 GHz. At 5 GHz, the length and width of the slot-ring are 42.72 mm and 0.2 mm respectively. At 10 GHz, they are 85 mm and 0.2 mm respectively The slot-ring antennas are loaded on obverse side of the Teflon glass fiber substrate. The thickness of the substrate is 0.8 mm with the relative dielectric constant εr of 2.15 and tanδ of 0.001. Four zero bias diodes (MSS20 146 B-10D: Aeroflex) are integrated with the slot-ring to realize the polarization detection. Diodes are loaded in every 45 deg. physical location on the slot-ring elements or at 0° and 90° physical location on the slot-rings to detect orthogonal linear polarization effectively. The proposed antenna can receive ±45° and 0° or 90° linearly polarized signal at 5 GHz and 10 GHz simultaneously. The structure of the antenna is very simple. The structure of the antenna is very simple. The antenna is fabricated and measured in an anechoic chamber. The measured results are provided and the results confirm the orthogonal detection ability successfully.

The performance of a Cognitive radio network depends on, how successfully the Secondary User (SU) can detect the present of Primary User (PU) and recognize the false alarm arises from interferences. In this research project, we determine the profile of probability of detection and probability of false alarm of a Secondary User under Rayleigh and Nakagami-m fading channels. Here, we use the combination of fading and Additive White Gaussian Noise (AWGN) as the impairments of the signal. We detect both the above parameters analytically and verified by Monte Carlo Simulation. The analytical and simulation results are found very closed to each other.In this project work, we evaluate the performance of cognitive radio network based on probability of detection and probability of false alarm. The received SNR is evaluated to provide Pf ≤ 8% and Pd ≥ 80% for Rayleigh and Nakagami- m fading channel. The analytical and simulation results are compared which provides 95% confidence level. The above work can be extended for chi-squired PDF where random variables are the square sum of Gaussian random variable, even for the case of weighted sum of random variable signal .Another further work can be inclusion of malicious user and observed of its impact on network performance.

ICT-IA-05: Performance of Optical Communication Channel using Source Coding and Channel Coding Technique

A. A. M. S. Sadman and M. H. Haider Dept of EECE, Military Institute of Science and Technology, Mirpur Cantonment Dhaka-1216, Bangladesh

In a general optical network, the messages from different sources are fed to analog to digital converter which transforms the messages into digital bits. These digital bits are represented electrically by Line coding technique followed by modulation. Subsequently the digital stream is transmitted through the optical fiber. Due to signal attenuation and dispersion, the data stream is corrupted which leads to evolve error in the receiver end. As bandwidth optimization is a big concern, the redundant information in the message needs to be curtailed. In this paper, two coding techniques are used in order to enhance the overall performance of optical fiber communication. The aim is to provide efficient coding technique which is able to code the data as well as detect and correct error in data due to transmission. Before performing Line coding, source coding algorithm can be performed which increases the information content of the source as well as upgrades the overall efficiency. When the messages are sorted according to their probability of occurrences and then coded, the unnecessary information in the message can be omitted. Afterwards, channel coding technique can be executed which adds some extra bits known as parity bits and ensures error free detection at the receiver side. The digital transmission of message can be enriched by giving each message symbol a unique code that helps the receiver to distinguish among the messages.

Steganography based secured image transactions are very much demanding processes for secured cryptographic electronic transactions. AnLSB and 256-bit key based AES cryptographic process has been designed, developed and implementedby using the Java programming language.First, the intended data image is encrypted with a 256-bit AES encryption algorithm that produced encrypted image data, put the encrypted data in an imageusing the LSB technique which produces the steganographic image and that is sent to the destination. In the receiving end, on the received encrypted data the same reverse process has been performed to retrieve the original image from the data. The process has been performed several times on different image data and a number of input/output are analyzed. It can be applied for higher level secured steganographic image transactions in applied cryptographic applications.

Steganography processes are very much demanding issues for secured image based cryptographic transactions. A noble steganography approach has been designed, developed and implemented by using Java programming language by using LSB technique in the symmetric cryptographic process. For this, DES algorithm is used to encrypt the image data, then the produced encrypted image data has been hiddenusing LSB steganography and is sent to the destination. In the receiving end, the received cipher data are decrypted by the same process in the reverse way to retrieve the original image from the data. In this process, though the attacker figured out the cipher image data found as its stego image, he/she can’t able to encrypt it without proper key and knowledge of that algorithm that was used. This can be applied for higher level secured image transactions for medical or applied cryptographic applications.

A. K. M. Akther Hossain Department of Physics, Bangladesh University of Engineering and Technology (BUET), Dhaka-1000, Bangladesh e-mail: [email protected]

Recent and current research projects on various metal oxides, diluted magnetic semiconductors (DMS), and nanocrystralline alloys carried out at the experimental solid state physics laboratory of department of Physics, Bangladesh University of Engineering & Technology will be described. For technological development and to meet new demand of the tomorrows society there is a constant need for smart multifunctional materials with improved properties. The fascinating properties of materials having perovskite and spinel structures have continued to attract interest of Scientists and Engineers. Multifunctional materials are a class of tailored materials that have more than one desired function (e.g. piezoelectricity, ferromagnetism, ferroelectricity etc), also known as multiferroics. There are two types of multiferroics: single-phase and composite (ferroelectric/ferromagnetic composites). The practical applicability of these single phase multiferroics in multifunctional devices is still in infancy due to some limitations such as limited magnetic response, dielectric constant and feeble magnetoelectric (ME) effect. The research themes emphasize synthesis, and characterization of multifunctional smart materials through the understanding of physical principles that govern materials properties. Experimental studies carried out by the active researchers in various branches of materials science such as multiferroics, nanocrystalline ferrites, DMS, colossal magnetoresistive (CMR) materials and colossal dielectric materials, with potential applications for read/write memory technologies, piezoelectric transducers, spintronics devices, magnetic field sensors, wave-guide, electrically tunable microwave devices such as filters, oscillators and phase shifters, current/voltage converters and non-volatile memories.

Cadmium Sulfide (CdS) and Copper (Cu) doped CdS thin films were deposited by spin coating method. Cadmium acetate (Cd(CH3COO)2) and cupric acetate(Cu(CH3COO)2.2H2O) were used as the precursors. Ethanol (C2H5OH) and Thiourea (CH4N2S) worked as solvent and stabilizer respectively. All the samples were prepared at 5000 rpm spin speed and annealed at 1500 C for 1 hour. The films appear as yellowish to light brownish in color as the Cu doping increases. The thicknesses of all samples were measured and were found near 100 nm. The effect of Cu doping on optical properties were investigated by UV-Vis NIR spectroscopy analysis. The transmittance spectra prepared from the spectroscopy analysis shows a decreasing nature as the doping concentration of Cu increases. Also the bandgap of 5 samples- Undoped CdS, 0.3% Cu doped CdS, 0.9% Cu doped CdS, 5% Cu doped CdS, 9% Cu doped CdS were calculated from Tauc’s plot and reported as 2.42 eV, 2.37 eV, 2.35 eV, 2.32 eV and 2.30 eV respectively. A decreasing nature was found for increasing Cu doping concentration due to the addition of extra energy levels which helps these structures to be used as tunable optoelectronic devices. The investigated optical properties from the experimental process resemble the theoretical analysis which will help the films to be used in various devices in future.

Nano-sized hydroxyapatite (HAP), Ca10(PO4)6(OH)2, powder was synthesized by ultrasonic 2+ 3- precipitation method in which [Ca(NO3)2+4H2O] and [NH4H2PO4] worked as Ca and PO4 sources, respectively. Sodium hydroxide was used to control the pH value of HAP during it’s production. Multi-walled carbon nanotubes (MWCNTs) were synthesized by chemical vapor deposition (CVD) method. The synthesized pristine MWCNTs were functionalized by means of strong nitric acid (HNO3). Nano-sized cobalt ferrites (CoFe2O4) were synthesized. Using homogeneous mixing method nano-HAP powder was doped with f-MWCNTs and CoFe2O4 at different wt% in order to get a series of HAP/f-MWCNTs/Cobalt-ferrite composites. The final composites were characterized by XRD, FTIR, and Impedance Analyzer. XRD analysis shows that crystalline peaks of the composite HAP/f- MWCNTs/ferrite were sharper than of un-doped HAP, f-MWCNTs and ferrite, which indicates that crystalline phases of HAP and ferrite on f-MWCNTs sidewall possessed high crystallizability. HAP/f- MWCNTs/cobalt-ferrite composites were sintered at 800oC. FTIR spectra confirm the bands 3- 2- corresponding to PO4 ( and CO3

In our country some research laboratories, scientific stores, communication control room, industries, medical places, insect rearing room etc. need a stable temperature and humidity for the proper functioning of their classified instruments or storage of food, beverage, medicine, growing of insects, plants etc. To maintain suitable temperature general purpose air conditioners are used in some cases and some time it is necessary to run the air conditioner all day long. This room air conditioners action also reduces the humidity of the room. But this humidity reduction hinders the purpose of the confined room and there need to take some measures to increase the humidity. Some humidification system also increases the temperature. This Ultrasonic Humidity Control System (UHCS) is designed to handle these delicate issues. The system is designed using a fast, powerful intelligent microcontroller and an Ultrasonic transducer for humidification. The control system monitors the humidity, switch ON/OFF transducer and maintain the preset humidity.

E-IIA-02: Improvement of Transient Response of a Motor Controller Based on Optimization Techniques

S. Hasan Department of Electrical and Electronic Engineering Islamic University of Technology (IUT), Gazipur 1704, Bangladesh e-mail: [email protected]

In this study, different kinds of tuning methods and optimization techniques for Proportional-Integral- Derivative (PID) controller, obtaining optimum values of transient response parameters, have been compared. DC motors are widely used in industrial applications, robotics and domestic appliances because of their high reliabilities, flexibilities and low costs. DC motor can be represented by nonlinear model when nonlinearities such as magnetic saturation are considered. To provide effective control of the motor, nonlinearities and uncertainties in the model must be taken into account for the control design. The model of a DC motor is considered as a third order system. The conventional PID controller is commonly used to control the speed of a dc motor in various applications since it is simple, robust and highly effective. PID Controllers designed by modified 5th generation Genetic Algorithm (GA) method and particle swarm optimization (PSO) techniques are compared for better transient performance and tuning. These methods are compared on the basis of transient response which includes parameters, such as minimum rise time, minimum settling time and minimum overshoot for speed demand application of DC motor. In this way, controller parameters for optimum motor speed and better transient response have been achieved.

T. Haque and H. K. Rouf Department of Electrical & Electronic Engineering University of Chittagong, Chittagong-4331, Bangladesh e-mail: [email protected], [email protected]

A surface plasmon resonance (SPR) sensor has been designed based on silver (Ag) - gold (Au) double metal layer by taking the advantage of higher sensitivity of Ag and chemical stability of Au which improve overall sensor performance. Integration of a Ti layer in the sensor configuration improves the adherence of metal on prism glass. Inclusions of an air gap also increase the sensor performance. Addition of a thin dielectric layer of InP enables SPs to spread along it and support a guided mode. There after SPR sensor performances are measured with different performance parameters including sensitivity factor or sensitivity, full width at half maximum (FWHM), detection accuracy and quality factor. Simulation has been carried out by using finite difference time domain (FDTD) method to study the reflectance curve and also metallic film optimization has been performed. The proposed sensor (Prism-Air gap-Ti-Ag-Au-InP Water) provides better sensitivity of 70.900/RIU and higher quality factor of 374.08 RIU-1. We also conduct a comparative study between basic Kretschmann configuration (Prism-Ag-Water) and the proposed sensor without Au layer. In that case proposed sensor without Au layer provides better sensitivity of 70.650/RIU against 52.820 for air and provides 2.4 times higher quality factor.

Integrated circuit design in the millimeter-wave regime needs some precise passive elements design in order to minimize insertion loss, lower return loss, good coupling and quality factor and lessen the total chip area. Various types of such passive elements are metal insulator metal (MIM), metal oxide metal (MOM), transmission line (TX) at several ohms with several patterns of signal line, ground wall and ground floor. 43

International Conference on Electronics and ICT - 2018, 25-26 November, 2018

Those passive elements are designed and mathematically optimized with several parameters of a metallic stack. Using High-Frequency Structure Simulator (HFSS) and Cadence circuit simulator (Spectre and MOMENTUM on 55nm DDC rules), these passive elements have been designed and then extracted best parameters from MATLAB optimized code. After designing the best layout structure, those passive devices have coalesced with active devices (several fingers CMOS Transistors) and practical equivalent circuit is taken under the optimization level. Here, a transformer coupled two or three metallic layer have been used instead of using highly dense twelve metallic stacks. Less amount of metallic recombination upgrades the quality factor and degrades insertion loss. Several stacked transformer have been evaluated with rectangular, hexagonal and octagonal pattern and their phase and amplitude imbalances have been optimized. Transformer coupled passive devices are used not only for signal transmitting but also making chip area smaller. A transformer coupled planar and stacked type both could be used for balun and power divider-combiner design. This type of balun provides small amplitude imbalance ~2dB and phase imbalance between 57-120 GHz bandwidth (BW) and successively shrinking the layout area of 0.0061 . On the other hand, transformer coupled two-way power divider-combiner (PD-C) occupies 0.0088 (7.5 Times Smaller than Wilkinson PD-C) with amplitude variation ~1.87dB and phase angle variation with larger BW (50-120 GHz). Again four way PD-C occupies 0.0122 (5 Times Smaller than Wilkinson PD-C) having amplitude variation ~2dB and phase angle variation with a larger BW 50-120 GHz. Proposed stacked small transformer with a center trapped balun and power divider-combiner has been implied on two millimeter-wave amplifiers on 55nm DDC CMOS.

Geiger Muller is one of the oldest and low cost detectors used for radiation monitoring in and around radiation facilities. The GM detector can detect alpha particles, beta particles, X-ray and Gamma ray based on radiation interaction mechanism. As GM detector is a counter, it is unable to provide the energy level of the radiation. Though the response of the detector is energy dependent. Specially for different energy level of gamma ray, the accuracy of the detector response varies. A robotic system with GM detector based survey meter has been developed for monitoring radiation level. As part of the performance analysis of the system, energy response of the detector has determined experimentally with different radio nuclides. The following energies are considered for the study: i) 662 keV from Cs-137, ii)1250 keV (avrg) from Co-60 and iii)1274 keV from Na-22. Based on the study it is found that the response of the GM detector is energy dependent within ±25%. In order to reducing the energy dependency, different filter can be used for energy compensation.

E-IIA-08: Na-ion Hybrid Solid-state Battery Technology (HSSBT) can Replace High Voltage Power Storage for Commercial Electric Flight

M. H. Sakif

Electric Flight is the present time great challenge to ensure clean sky, reduction of global warming and flight cost. Renewable energy based electric flight can be the best alternative of Fuel. But the prime limitation is high voltage power storage cell and reliable power management system. Our newly designed Na-ion solid-state hybrid battery technology can be the best solution for safe E-flight and high voltage renewable power grid storage. It stores electric charge at the surface of electrodes and Di-electric medium creating electric field by Electro-static process rather than electrochemical process. So, no Redox reaction needs to occur in HSSBT, which increases the cycle life of storage and chemical stability. Beside these Ultra capacitor provide negative linear variable voltage output with low specific energy. In galvanic, cell reaction rate is responsible for power output. That’s why purity of materials need to ensure to control cell state variation among each cell. The electrolytes use in battery is very toxic and corrosive, which are harmful for environment. But in our HSSBT, aqueous NaCl solution with cellulose fiber colloid is used as dielectric medium and ion transport medium. The materials are naturally available. A shunt integrated circuit is used to regulate amp-voltage ratio for appropriate power output. Recent research is running on electrochemical storage and simple ultra capacitor cell which has cell state variation and not suitable for E-flight Therefore our technology is very eco friendly, sustainable and reliable. It is Highly Economical project on which Future world going to depend on.

IT-IV: Nanostructured Materials: Powerful Weapons for Environmental and Bacterial Remediation

M. A. Hakim Department of Glass and Ceramic Engineering (GCE), Bangladesh University of Engineering and Technology (BUET) e-mail: [email protected]

The revolutionary discovery of antibiotics by Alexander Fleming has opened a new dimension in medical science to combat with bacteria. Unfortunately, recently we observe that antibiotics are losing glamour as the bacteria are becoming highly resistance to drugs. Misuse along with unplanned and excessive usage of antibiotics have become a critical issue that the bacteria have become resistive to antibiotics. We are really coming with a very dark part of the civilization that one day the antibiotic will completely inactive to human dieses due to this growing of resistance of antibiotics. Now the only solution that is coming along is the nanotechnology. Ceramic/ metal oxide nanoparticles have a unique capability to kill the bacteria without any effort using their semiconductor or band gap property. There have been many nanomaterials both metallic and oxide materials that have been proved to be very powerful weapon to combat the spread and growth of bacteria. Among these materials we can name few like- Ag, Au, TiO2, ZnO, CeO2, Cu2O and different types of spinel ferrites like Co-ferrite, Mg-ferrite and many others to name a few. In this report we describe the mechanism in brief that is responsible for these type of unique applications of nanomaterials. This is not only limited to disintegration of bacteria but it is also connected to environmental pollution which has become a deep concern of this 21st century and the alarming global warming and climate changes. Our environment is completely polluted with the booming industrial and high population growth. One f the major problem of our environment is the pathogens and pollutants organic as well as inorganic that are surrounding our home, industry, school, college and everywhere. The best way to get rid of these wide spread bacteria is to make our environment capable to eliminate or kill the bacteria or to get remediation from bacteria.

F. M. Kamal, M. N. I. Khan and R. Rashid Materials Science Division, Atomic Energy Centre, Dhaka-1000, Bangladesh e-mail: [email protected]

The proposed study is to develop a new method for effective atomic accumulation by controlling temperature distribution. This controlling temperature distribution has been done by introducing sudden changes in cross sectional area of the metal line. Temperature gradient due to the sudden changes in cross sectional area for atomic accumulation was analyzed theoretically. Then the verification of the methodology has been performed experimentally. The evaluation of the accumulation has been analyzed on the samples with natural oxide layer and also the layer with a hole. The experiment has been done to attain more atom accumulation by taking samples with different width ratio. After the experiment, the sample was examined under ﬁeld emission scanning electron microscope. Finally, microspheres were fabricated at the predefined location in the sample with a sudden change in geometrical shape, which demonstrates the effectiveness of the present technique in fabricating micro and nano materials.

NT-IIB-02: An Investigation of the Properties of Co-60 Gamma Irradiated Orthorhombic Molybdenum Trioxide (α-MoO3) Nanoparticles

Orthorhombic (α-) MoO3 nanoparticlesis a wide bandgap semiconductor material, which recently attracted significant attention for optoelectronic, sensing, and smart windows etc. applications. In this work, α-MoO3 nanoparticles with average crystallite size (non-exposed) of 135.31 nm was successfully synthesized by the hydrothermal method.The nanoparticle samples werethen exposed to gamma ( ) radiation doses from 60Co source. A dose range of 20 kGy to 100 kGy has been applied with an incremental dose step of 20 kGy. Radiation effects on α-MoO3 nanoparticles have been investigated for the first time using XRD, FESEM, FTIR and UV-Vis-NIR spectroscopy techniques. The XRD patterns reveal that the average crystallite size decreases to 127.79 nm at a low dose of 20 kGy and after that gradually increases up to 136 nm at 100 kGy. The lattice strain and dislocation density, however, shows the opposite trend observed in the case of the crystallite size modification with absorbed doses. This result presents good evidence for the deterioration of crystallinity for low doses and improvements for high doses. The FESEM results show the significant effects of gamma doses on the micrographs of layered structure and grain size. The optical studies reveal that band gap varies within a range of 2.74 eV to 2.90 eV, and this may be due to the modification of electronic localized states. These results suggest that α-MoO3 nanoparticlescan tolerate high doses of gamma radiation, making it a promising candidate for optoelectronic and photonic devices for γ-ray exposure environment applications.

Recently the concept of a unique photoluminescent material capable of Reactive Oxygen Species (ROS) generation has created enormous enthusiasm in the field of Photodynamic Therapy (PDT) for the destruction of pathogens as well as localized cancer cell researches. Here, we report the synthesis of CeO2 nanoparticles (NPs) via green synthesis method using A. heterophyllus leaf extract as bioreducing agent varying the concentration of Ce(NO3)3.6H2O precursor. Structural analysis of the synthesized samples was performed by X-Ray Diffraction technique (XRD) which indicated the presence of crystalline CeO2 phase and Reitveld refinement confirmed the presence of Monazite- CePO4 as second phase. From the FT-IR analysis of the leaf powder it was found that P-O bond was present in the leaves which in turn, generated CePO4 as a natural capping effect of green synthesis. 47

Surface morphology was observed by FE-SEM images which revealed spherical and agglomerated NPs. The heterostructure showed efficient antibacterial activity against both gram positive (S. aureus) and gram negative (E. coli) bacteria. Cytotoxic experiments confirmed that the synthesized NPs are non-toxic up to 1000 μg/ml concentration having the capability of cancerous cell destruction at much higher rate than non-cancerous cells with the increase in concentration up to 5000 μg/ml. This CeO2:CePO4 nano heterostructure may further find its application as enhanced conversion capability nanoparticles for efficient PDT in cancer treatment.

Garnet ferrites are important magnetic materials for microwave and magneto-optical applications. In thisreport we present the synthesis of Gd and Co co-doped Y3Fe5O12(YIG) nanoparticles by sol–gel method and their characterizations. The effects of Gd3+ and Co3+ substitution on the structural and magnetic properties of Y2.8Gd0.2Fe(5-x)CoxO12(x= 0, 0.1, 0.3, 0.5) nanoparticles were investigated. Precursor salts of yttrium, Iron, Gadolinium and Cobalt were used as starting raw materials. Synthesized nanoparticles were annealed at various temperatures between 7500C and 11000C to observe the crystallinity. X-ray diffraction (XRD) and Rietveld analysis confirmed the presence of well-defined crystalline Cubic(Ia-3d) structure without any secondary phase for un-doped YIG. But for Gd-Co co-doped YIG samples the major phase was found cubic type structure with negligible amount of impurity phases of perovskite structure which is Orthorhombic (Pna21). The field emission scanning electron microscopy (FESEM) images revealed irregular shaped particles with various grain sizes from 10nm to 200nm depending on Gd and Co doping. Magnetic properties of this co-doped sample were investigated and a substantial change of magnetization of 23 emu/g was obtained for Y3Fe5O12 compared with 21 emu/g for Y2.8Gd0.2Fe5O12 and 22.7 emu/g for Y2.8Gd0.2Fe4.9Co0.1O12.

Nanocrystalline materials are synthesized by various techniques, among them green synthesis of nanoparticles have attracted a considerable interest to the researchers as it is environmental friendly, cost effective and facile. In our study, manganese dioxide (MnO2) nanoparticles (NPs)were successfully synthesized through the

International Conference on Electronics and ICT - 2018, 25-26 November, 2018 reduction of potassium permanganate using Bryophylum pinnatum (PKL) leaf extract as a source of reducing and capping agents. The elemental nature of MnO2NPs and the presence of capping agents on the surface of MnO2NPs were evidenced from the Energy Dispersive X-ray (EDX) spectroscopy analysis. The Fourier Transform Infrared (FT-IR) spectra also proved the presence of reducing and capping agents in the leaf extract and capping agents on the surface of synthesized MnO2NPs that stabilized the MnO2NPs. The surface morphology of MnO2 NPs was examined using Field Emission Scanning Electron Microscopy (FESEM) technique and showed that the synthesized NPs were spherical in shape with minimal agglomeration which might be due to the presence of capping agents on the surface of MnO2 NPs as also evidenced from EDX and FT-IR analyses. The crystallinity and phase was identified with the help of X-ray Diffraction (XRD) technique that showed that the synthesized MnO2 NPs were crystalline in nature. The average crystallite size was also calculated from the XRD patterns and found to be 41 nm. The thermal analysis was carried out using Thermogravimetric Analysis (TGA), which also indicated the presence of capping agents on the surface of synthesized MnO2 NPs. The synthesized MnO2 NPs were then applied for electricity generation in a modified galvanic cell, where MnO2 NPs and water were used as electrolyte. The efficiency of the synthesized MnO2 NPs was calculated as 86% measured from the voltaic efficiency, for only 0.1% MnO2 NPs and water used as electrolytes indicating the potentiality of MnO2 NPs.

Silver nanoparticles have attracted a remarkable interest to the scientists due to their potential applications especially in the medical sector. Magnetic nanoparticles are reported to show noble biological activity. Bulk silver is non-magnetic in nature. But, bio-molecule encapsulated silver nanoparticles is thought to be magnetic. Thus, silver nanoparticles were synthesized by adopting a newly developed green synthesis technique. It was observed that successful synthesis of bio-molecules capped Ag NPs of average diameter 13 nm was possible by using AgNO3 solution as a precursor and Artocarpus heterophyllus leaf extract as a reducing and capping agent. Such realization came into view after performing the characterization studies of the synthesized Ag NPs through various techniques such as UV-Visible (UV-Vis.) spectroscopy, Energy Dispersive X-ray (EDX) spectroscopy, Fourier Transform Infrared (FT-IR) spectroscopy, Field Emission Scanning Electron Microscopy (FESEM), Transmission Electron Microscopy (TEM), Thermogravimetry (TG) and Vibrating Sample Magnetometer (VSM) analyses. From the VSM analysis a hysteresis loop wasobtained indicating a weak ferromagnetic behavior of the Ag NPs with saturation magnetization of 0.085 emu/g and coercivity of 149 Oe. It is speculated that the ferromagnetic nature of Ag NPs might be due to the spin polarization. Moreover, the weak ferromagnetic property of Ag NPs might be due to the weak coupling between the capping agents and the Ag surface Moreover, the presence of oxygen in the sample predicting the presence of non-stoichiometric oxide layer on the surface results to the ferromagnetic nature of Ag NPs.The presence of ferromagnetic behavior of the synthesized Ag NPs is indicating the success of our present study in synthesizing the organic molecule capped magnetic Ag NPs using Artocarpus heterophyllus leaf extract and AgNO3 solution.

Magnetic nanoparticles (MNP) have wide practical applications in different areas including magnetic storage media, catalysis, ferrofluid, environmental remediation, drug and gene delivery system, cell separation, and magnetic resonance imaging (MRI). However, naked MNPs have some limitations since the aggregation of naked MNP is practically unavoidable due to their high surface energy, van der Waals force and the dipole-dipole magnetic attraction among particles. In order to overcome this problem, a typical method is to use matrix materials to isolate, accommodate and stabilize individual MNP is of great interest. In the present investigation Zn ferritenanoparticles have been synthesized by auto-combustion method using 2, 4, and 6 wt% of octadecylalkylammonium intercalated montmorillonite (ODA-MMT) as supporting material. Structural characterizations of pure ferrite and ODA-MMT supported ferrite were performed using XRD, SEM and FTIR techniques. Magnetic and dielectric characterizations of the samples were also made. This investigation may open the door for tailoring the porosity, grain size, magnetic and electric properties of Zn ferrites using appropriate amount of ODA-MMT as matrix materials which may eventually helpful for diversifying the applications of ferrite materials.

Convinced of the necessity of finding new sources of antibiotics, Titanium Dioxide (TiO2) nanoparticles (NPs) were synthesized by adopting a newly developed bio-synthesis technique and concomitantly evaluated their cytotoxicity effect against cancer cell and antibacterial activity against different pathogenic bacteria. Titanium dioxide nanoparticles have been successfully synthesized through the reduction of Titanium (IV) tetra iso-propoxide using Artocarpus (A.) heterophyllus (Jackfruit) leaf extract as a source of reducing and capping agents. The as-prepared TiO2 is then calcined at 500 ºC in order to obtain anatase type crystalline TiO2 NPs. The elemental nature of TiO2 NPs and the presence of capping agents on the surface of TiO2 NPs are evidenced from the Energy Dispersive X-ray (EDX) spectroscopy. The Fourier Transform Infrared (FT-IR) spectra also proves the presence of reducing and capping agents in the leaf extract and capping agents on the surface of 50

synthesized TiO2 NPs that stabilize the TiO2 NPs. The surface morphology of TiO2 NPs is examined using Field Emission Scanning Electron Microscopy (FESEM) technique and shows that the synthesized NPs are spherical in shape with minimal agglomeration which might be due to the presence of capping agents on the surface of TiO2 NPs as also evidenced from EDX and FT-IR analyses. The crystallinity and phase is identified with the help of X-ray Diffraction (XRD) technique that shows that the synthesized TiO2 NPs are of highly crystalline with anatase phase. The crystallite size is also calculated from the XRD patterns that estimated as 15 nm which also agrees with the Transmission Electron Microscopy (TEM) results. The thermal analyses are carried out using Thermogravimetric Analysis (TGA) and Differential Scanning Calorimetry (DSC) techniques. The magnetic property of TiO2 NPs is evidenced from the Vibrating Sample Magnetometer (VSM) measurement and found to be ferromagnetic in nature. For the bio-medical applications TiO2 NPs are exposed to gram positive and gram negative bacteria and proves that the NPs are effective against both types of bacteria. Moreover, the synthesized TiO2 NPs are exposed to two types of cell, HeLa cell which is a carcinoma cell and Vero cell which is a normal cell, and from the cell viability measurements it is evidenced that the phytosynthesized TiO2 NPs decreases the carcinoma cell viability indicating their suitability as an anticancer agent.

M. K. Hossain, M. O. Faruk, S. Sardar and M. S. Akbar Rooppur Nuclear Power Plant Project, Bangladesh Atomic Energy Commission, Dhaka, Bangladesh e-mail: [email protected]

Nuclear Power Plant (NPP) is characterized by technical complexities. The development of competent manpower is one of the fundamental requirements for safe and secure operation & maintenance of the NPP. In most cases, the safe and economic operation of NPP depends on knowledge and skills of operational personnel. It is a critical infrastructural issue to the countries embarking on their first NPP. The number and qualifications of manpower required for a successful nuclear power project are sometime underestimated and the resulting shortage of manpower is a restraining factor against development of nuclear technology, in particular, in developing countries. Before embarking on first nuclear power plant project, it is essential for a newcomer country to determine its real manpower needs in the framework of the envisaged nuclear power program and evaluate the existing organizational, educational and industrial capabilities for meeting these needs. For Bangladesh, a well- planned human resource development plan is in place to run the program in a sustainable manner. Based on the country culture and IAEA guidelines, 2535 personnel have been identified in different categories for Rooppur NPP units (VVER, 1200 MWe each of 2-units). The identified personnel have already been started to recruit and training and the rest will be recruited and trained sequentially. They will be trained for Rooppur NPP project management, plant commissioning and operation & maintenance. Among them 1424 key personnel will be trained by the Contractor in the frameworks of General Contract wherein required personnel will obtain license in compliance with regulatory requirements. Administrative and common industrial personnel as well as general supporting staffs will be trained locally by the Customer’s trained instructor as required. This paper deals with the availability of human resources for Rooppur NPP and their training plan to make them competent enough to run the NPP independently.

NE- III -02: Cyber Threat Assessment for Nuclear Power Plant

M. O. Faruk, M. A. Huq and M. S. Akbar Bangladesh Atomic Energy Commission e-mail: [email protected]

Cyber security is an indispensable part of the security regime of nuclear power plants (NPPs). However, cyber security of NPPs is still considered to be in the early phase of development. The existing literature on the Cyber Security of NPPs is very abstract, and also, largely unstructured. The key problem seems to be the lack of standards, methods and frameworks for identifying cyber threats and incorporating the latest security trends, which can holistically combat the cyber-attacks that target NPPs. In spite of these short comings, any nuclear power plant must regularly assess the potential cyber threats and devise countermeasures. Cyber threat assessment consists of methods and procedures used to assess the effectiveness of cyber security controls in a digital system. In particular, the assessment methods and procedures are used to determine if the security controls are implemented correctly, operating as intended, and producing the desired outcome with respect to meeting the security requirements of the asset owner. Cyber threat assessment is one of the most reliable methods of determining whether a system is configured and continues to be configured to the correct security controls and policy. The assessment methodologies and tools described in this document are meant to assist Nuclear Power Plant (NPP) in keeping its systems operationally secure and as resistant as possible to attacks. To produce an assessment that is credible, accurate, and effective, it is critical that all involved parties—including the state, government agencies, regulators and operators—work closely together.

NE- III -04: External Communication Network and Public Notification System: Rooppur NPP Perspective

S .Z. Tasnim, M. O. Faruk and M. S Akbar Bangladesh Atomic Energy Commission e-mail: [email protected]

Bangladesh is implementing country’s first Nuclear Power Plant (NPP) Project, Construction of Rooppur NPP Project. To successful implementation and operation of Nuclear Power Plant, external communication network and public notification system is one of the key infrastructures of NPP. Aneffective, reliable, independent communication system is a must for every NPP. It has to be functional not only in normal operation mode but also in emergency case and it should also include the public notification system. The NPP communication and public notification complex is designed to provide effective, reliable and sustainable operational management, administrative and economic management at the NPP in the daily activities and emergency situations as well as timely notification of NPP personnel, residents of near-station town (settlement), communities and industrial facilities located in the five-kilometer area, reception and transmission of notices. This paper describes a theoretical model of external communication network and public notification system considering the perspective of Rooppur NPP.

Dense Plasma Focus (DPF) device is a hydrodynamic co-axial plasma accelerator which emits powerful pulsed radiations. The device can be constructed with different size and power (sub- kilojoule to mega joule), but every machine produce same energetic neutrons and X-rays. Machine with small size and power are gaining popularity because of their compactness and usefulness. A small sub-kilojoule DPF device can have applications in material modification, substance detection, neutron activation analysis, medical neutron therapies, humidity measurement, next generation microelectronics lithography, surface micromachining and so on. In this research a simulation has been conducted on a sub-kilojoule device (PF-400J) to find the optimum neutron yield ( ) as a function of filling gas pressure ( ). The simulation package is the Lee Model code (RADPFV5.15de.xls), which couples the electrical circuit of the machine with Plasma Focus dynamics, thermodynamics, and radiation enabling a realistic simulation of all gross focus properties. The machine was fitted into the simulation package inserting data from the laboratory data and by manipulating the model parameters ( , , and ). The fitting was completed when the current profile of the simulation matched satisfactorily with the laboratory recorded current profile. Then neutron yield ( ) was recorded with different filling gas pressure ( ) starting from0.75 to 11.25 torr maintaining a 0.75 torr gap.The filling gas was Deuterium. The maximum is n found at 4.75 torr pressure by the numerical experiment. This finding is quite agreeable with the laboratory experiment. Detailed discussion on the results of present study with numerical method will be given in the presentation.

NE- III -06: An Assessment on the Accidental Nuclear Occurrences: Bangladesh Perspective and the State of Our Preparedness

N. B. Ahmed1, S. Khan1, K. N. Tahsin1, A. A. Jiku1 and I. Afrida2 1Independent University Bangladesh, Dhaka, Bangladesh 2Military Institute of Science and Technology, Dhaka, Bangladesh e-mail: [email protected]

This paper explores the effects of accidental challenges occurred from national nuclear programs, and the state of the preparedness of the people of Bangladesh to face and minimize it. The uses of nuclear energy in peaceful applications have been of much interest for years. Along with the rest of the world, Bangladesh is also utilizing this at its most in carrying out research and extending services at different fields. But majority of the people don’t have any idea at all about this, and they lack knowledge on how to face the aftermath challenges if any disaster takes place. The Rooppur nuclear power plant is currently progressing which is the country’s first nuclear power plant. A survey was conducted among people based on few parameters related to the applications of nuclear energy; such that, basic idea of nuclear usage, how to face the challenges, workshop attended etc. We asked around 40 people and It was found that only 40% was possessing a good idea about this. Only less than 3% people has little idea about how to avail protection in case any nuclear downfall occurs. While many countries have launched campaigning and other mass awareness protocols after the Chernobyl accident occurred in 1986, we are still lagging behind to get our people aware of it and get them prepared. It was found that very few people know about the country’s first nuclear power plant. The survey shows that almost 90% Bangladeshi people feel that they need more adequate knowledge on nuclear applications and availability of workshops conducted on both its positive and negative effects.

M. M. Alam1, M. D. Hossain1, M. S. Ahmed1, M. A. Habib1 and N. K. Datta1 1Institute of Computer Science, Bangladesh Atomic Energy Commission, Dhaka, Bangladesh e-mail: [email protected]

Now-a-days social media especially Facebook (FB) becomes one of the most powerful media where most of the people always keep in touch with it. Numerous studies have been emphasized that FB is a state-of-art media to exchange information among mass people in an interactive, cooperating and dissemination manner. Research communities have been highlighted that FB may be the most effective communicating media with the public during nuclear and radiological emergencies. Since risk information has lot of challenges to create the right message in right time and sometimes the messages may create public misconception, anxiety and misunderstanding about risk, FB media helps information provider to overcome the lacking and challenges about risk information. Analyzing the public comments and feedbacks from the FB post help risk communicator to understand mass people thinking about the risk, their actions to handle the risk, their stress and anxiety, miss understanding of the risk and so on which may help to modify and upgrade the risk information. It is the key point to provide smart, operative, solution oriented and trusted support to the stressed and nervous people during nuclear and radiological emergencies. To analyzing the public comments and feedbacks from the FB post about risk information during nuclear and radiological emergencies, a software agent and computational platform has been developed. Theses a software agent and computational platform collect public comments and feedbacks and other relevant data such as sharing, like and so on from the FB post of risk information, classify the data and information into several groups, analyze the data and information and appropriate suggestion to update and modification the risk message or information. These software agent and computational platform present public comments and feedbacks to the authority for taking the necessary steps.

S. Pervin1, S. Yeasmin1, J. Ferdous1 and A. Begum2 1Health Physics Division, Atomic Energy Centre Dhaka 2Department of Physics, Bangladesh University of Engineering and Technology e-mail: [email protected]

In this study, radon concentrations in tap water samples were measured in Dhaka city in Bangladesh by using a technique called Durridge RAD7-H2O with closed loop. It was found that, the range of radon concentrations varied from 0.07±0.014 Bq/L to 4.80±0.548 Bq/L with the average value 2.67±0.66 Bq/L. The results were below the radon concentrations of the internationally recommended reference levels of World health Organization limit (500 Bq/m3 ) and the maximum contaminant level (11.1 Bq/L) recommended by US Environmental Protection Agency. The calculated average annual effective dose was found 0.0097 mSv/y which was also below the WHO recommended reference levels of annual effective dose due to radon in drinking water values 0.1 mSv/y. So the tap water of this study area is safe from the standpoint of radon concentration.

Chowdhury2 1Analytical Chemistry Laboratory, Chemistry Division, Atomic Energy Centre, Dhaka 2Department of Applied Chemistry and Chemical Engineering, University of Dhaka e-mail: [email protected]

Contamination of heavy metals in Water is regarded as a global crisis with a large share in developing countries like Bangladesh. Nine heavy metals such as Lead (Pb),Chromium (Cr), Cadmium (Cd),Mercury (Hg),Arsenic (As),Iron(Fe),Manganese(Mn),Zinc (Zn) and Nickel (Ni) in sediment and water were investigated from South-Westerncoastal region in Bangladesh. The decreasing trend of metals were observed in water as Fe>Mn>Zn>Pb>As>Cd>Cr>Cu>Hg and in sediment were Fe>Mn>Zn>Cr>Ni>Pb>As>Cd>Hg . The ranges of Pb, Cd, As, Fe, Zn and Mn of heavy metals in water were 13-25,1-1.5, 2.05-3.084, 254.11-1154.71, 10.4-29.61, 219.22-250.92 µg/L respectivelyand in sediments were 10.5-17,0.1-0.5,22.67-30.37,47.42-59.19,0.009-0.034,1.87-2.76,20844- 25499,403.55-513.22,19.2-27.5 mg/kg respectively.The concentration of the surface water samples were not exceeded the permissible limits. The data monitored have been used to compute heavy metal pollution index using weighted arithmetic mean method and the proposed pollution index (HPI) and heavy metal evaluation index (HEI) seem to be applicable in the assessment of overall water quality with respect to heavy metal pollution whichindicatesthe water to free from heavy metal pollution. The pollution loadindex (PLI) and contamination factor (CF) were used to assess the human health risks posed by heavy metals through sediments.

NE- III -10: Role of Nuclear and Renewable Energy in the Optimal Power Generation Mix of Bangladesh

J. Sieed1*, M. O. Faruk1 and D. M. Shawkat Akbar1,2 1Bangladesh Atomic Energy Commission 2Nuclear Power plant Company Bangladesh Limited e-mail: [email protected]

Being one of the fastest developing countries with consistent GDP growth for consecutive years, Bangladesh faces the challenge to meet the ever-increasing demand for energy, particularly electricity. Though natural gas has been playing significant role as the primary energy source, depleting resources make it inevitable to search for new options. Coal might be a better choice due to the availability of indigenous resources, but over-dependence on coal might have long term effects on the environment and global warming. Also, the proposal made through Power System Master Plan 2016 to import coal for power production does not seem to be a sustainable solution due to transportation and emission issues. The remaining options that could be feasible in the long run are nuclear and renewables. Bangladesh has already started building its first nuclear power plan consisting two reactors. And, the experience and confidence gained from this project might help in the long run to go for more base- load nuclear plant those could be both economically and environmentally beneficial. In addition, intermittent solar and wind energy sources are also becoming more efficient and cost effective with the progression of time which make them the best option for variable loads. Battery storage options could also be used more efficiently in near future for getting the best out of the renewable sources. An Optimal power Generation Mix Model with least cost objective function has been analyzed with existing Bangladesh energy data and growth pattern and it confirms that both nuclear and renewables would be good enough to supply more than half of the energy demand in fifty years. Coal, gas and other traditional options will also exist, but only nuclear and renewable energies have the potential to satisfy out electricity demand both economically and, in an environment, friendly way.

IT-VII: Dhaka University Telemedicine Programme – Innovations in Technology and Service Delivery

K. Siddique-e Rabbani Honorary Professor Department of Biomedical Physics & Technology, University of Dhaka Director, Dhaka University Telemedicine Programme e-mail: [email protected]

In Bangladesh no qualified doctors are available for consultation to almost 70% of the population living in villages. For common ailments they either go untreated or take medicines from phramacists, village doctors or quacks, often leading to complications, emergencies, even death. Besides, this also has caused heavy misuse of antibiotics and steroids, which now threatens the whole humanity. Therefore, TELEMEDICINE using the internet seems to have the potential to provide at least some redress to the situation; for both health awareness and for providing primary and secondary healthcare.A team of youths under the leadership of the author started developing technology for Telemedicine in 2011, which included both software and integrated online diagnostic devices like Stethoscope and ECG. The software provides patient management, doctor’s video consultation, prescription generation and archiving in web storage. Implementation is done through entrepreneurs who establish rural telemedicine centres. Operators with computer expertise need only a three day training. Patients consult doctor through the operator at these centres. They can choose any doctor who is present in this system. Doctors can work from anywhere where there is internet link, even when

International Conference on Electronics and ICT - 2018, 25-26 November, 2018 they are on the move. The service delivery model includes charging a minimum patient fee and provision of poor fund support for those who can provide a genuine claim. Field trial started in 2013 and on its success the department started disseminating the technology throughout Bangladesh with appropriate permisssions under the name, ‘Dhaka University Telemedicine Programme (DUTP)’ in November, 2015. At present 14 city doctors are providing consultations and the number of rural centres stand at 41, more to follow. Till now more than 16,000 patient consultations have been provided. 75% of the patients were females, children and elderly, most of whom would not have taken any treatment at all, or would get maltreatment, had these centres been not there.Since the team of technology developers and the team for service delivery work under the same leadership in close proximity, user feedback are being promptly addressed as much as possible, enabling a quick improvement of the whole system. So far DUTP has received several national and international awards including WSIS-2017 and 3rd Commonwealth Digital Health Awards-2018. All the experience has made the team of the Dhaka University Telemedicine Programme (DUTP) well prepared to help and support teams in other LRCs who want to introduce telemedicine in their countries.

BE-IVA-01: Development of a Low-cost Static Syringe Infusion Pump for Thalassemia Patients

M. Al-Amin, N. Mahmood, M. Moniruzzaman and K. Siddique-e-Rabbani Department of Biomedical Physics & Technology, University of Dhaka, Dhaka e-mail: [email protected]

Thalassemia is the most common congenital disorder in Bangladesh as in many parts of the world. Everyday 38 Thalassemia Patients born in Bangladesh and 10% of Bangladesh’s population are Thalassemia carrier. However, Thalassemia Patients must be taken iron reducing injectable medication Desferrioxamine subcutaneously with a syringe infusion pump over 6-12 hours for 5 days/week. But the syringe infusion pump is not available & affordable for Thalassemia Patients in Bangladesh. Those are imported from abroad with the high price and they are not also adaptive to our environment. So Dhaka Shishu hospital came up with the requirement of having an appropriately designed single syringe infusion pump to assist the patients in this regard. The group at the Dhaka University designed and implemented a solution using a microcontroller based device that delivers fluids, such as nutrients and medications, into a patient’s body in a controlled amount over a long span of time, selected by the user that is robust and durable. Firstly, a Polyvinyl Chloride (PVC) pipe, lead screw & dc motor were considered and studied in detail for the syringe driver. Later, this was replaced by the 3D printed coupler, syringe holder, acrylic sheet, lead screw & dc motor. The timing and controlling the motor was performed using microcontroller based circuitry. This makes the system versatile and easily adaptable to various needs and the cost was also reasonably low. The system is powered by a 3500mAH rechargeable battery which will run for about 18 hours before a need for recharging and AC supply is also properly interfaced with this system. So during injection period, this system will not be stopped when AC supply is interrupted. This system also has multiple user selectable flow rates and blockage detection. The prototype was designed to follow Dhaka Shishu hospital’s requirements and performed with satisfaction. It is hoped that this device will be beneficial to Thalassemia Patients in Bangladesh and other low resource countries.

BE-IVA-02: A New Six-Electrode Electrical Impedance Technique for Probing the Deep Tissue Organ of the Human Body

S. K. Roy1, M. A. S. Karal1, M. A. Kadir2 and K. Siddique-e-Rabbani2 1Department of Physics, Bangladesh University of Engineering and Technology, Dhaka-1000, Bangladesh 2Department of Biomedical Physics and Technology, University of Dhaka, Dhaka-1000, Bangladesh e-mail: [email protected]

Electrical impedance measurements of biological tissue have potential applications in many physiological investigations. Two existing methods, tetrapolar Impedance Measurement (TPIM) and Focused Impedance Method (FIM) are typically applied from one side of the body. So they have a limited depth sensitivity which may be used only to study objects at shallow depths. However, for studying objects at deeper regions of the body, particularly of the human thorax, a different approach needs to be taken. The present work used a novel six electrode configuration in which two current electrodes, in the form of vertical strips, were fixed at right and left extremes of the thorax, below the armpits. Two potential electrodes were placed on the front in a horizontal plane and the other electrodes were placed at the back in the same horizontal plane, and at corresponding symmetrical positions. Each of the two symmetrical electrodes in the front and back were connected together for getting the resultant potential measurement. In the present work, Finite Element based COMSOL Multiphysics was used for 2D and 3D sensitivities considering the thorax as an elliptical cylinder. The sensitivity was almost uniform within the volume conductor and at the deepest point was about 75% of that near the surface for a potential electrode separation of 10 cm. On the other hand for one sided TPIM, the sensitivity keeps on decreasing from the surface and goes down to about 35% at the centre for the same potential electrode separation. Phantom measurements were then made using a circular shaped made of plastic containing saline and fixing electrodes appropriately on the surface. The sensitivity values were almost identical with the software simulation result. Therefore, the novel six-electrode configuration may be useful for electrical impedance study of deep organs of the human thorax.

Recently, an extensive research has been focused on nano-structured magnetite (Fe3O4) nanoparticles (NPs) because it possesses unique magnetic and electric properties and its application in medical diagnosis and therapy, target drug delivery, magnetic resonance imaging, cancer hyperthermia treatment and antibacterial activity against gram positive and gram negative bacteria. Various methods of synthesizing Fe3O4 NPs have been developed such as Chemical precipitation method, which, involves co-precipitation of ferric ions Fe (III) and ferrous ions Fe (II) by sodium hydroxide NaOH or ammonia solution NH3.H2O, thermal decomposition of organic iron precursor in organic solvents, Polyol process, sol-gel method, sonochemical synthesis, solvothermal synthesis, hydrothermal synthesis, mechano-chemical processing and emulsions technique. In this study, we propose a rapid, non-toxic, facile and green synthesis route to prepare magnetite nanoparticles in only one step reaction. Ferric chloride anhydrous and ferrous chloride tetra hydrate, Ipomoea aquatica leaf extract and sodium hydroxide were used as starting materials. Magnetite nanoparticles can be obtained in a relatively low temperature range 60-80℃. An aqueous solution of ferric chloride hexahydrate, ferrous chloride tetra hydrate with 2:1 molar ratio was mixed with Ipomoea aquatic leaf extract and heated for 5 minutes at 60℃. The synthesized magnetite nanoparticles were characterized by X-ray diffraction (XRD), Energy Dispersive X-ray Spectroscopy (EDS), Field emission scanning electron microscopy (FESEM), Transmission Electron Microscopy (TEM), Fourier transform infrared Spectroscopy (FT-IR), Dynamic Light Scattering (DLS),

Magnetic Nanoparticles (MNPs) have been increasingly integrated into biological systems, making it imperative to understand their interactions with cell membranes, the first barriers to be crossed to enter cells. These interactions can be studied in detail using artificial lipid bilayers, which can provide insight into the nature of the nanoparticle-membrane interaction through variation of membrane and solution properties not possible with cell-based assays. Here, 20% dioleoylphosphatidylglycerol (DOPG)/80% dioleoylphosphatidylcholine (DOPC)-GUVs and 10%DOPG/90% DOPC-GUVs (%indicate mole%) were prepared by the natural swelling method as a model membrane system. Ipomoea aquatic extract mediated green biosynthesis method is used to the synthesis of MNPs. The mean particle size of the MNPs was about 15 nm. To observe the interactions between lipid membrane and MNPs, GUVs of size 10µm or more (similar to cell) were used. The changes of GUVs due to the interaction of MPNs were observed under the inverted phase contrast microscope. In presence of low MNPs concentration, GUV change their shape due to the area difference between outer and inner monolayer. Thereby, at high concentration of MNPs formed pore in the membrane of GUVs due to the localized pressure induced by electrostatically adsorbed MNPs. These results might be helpful to study the mechanism for killing antibiotic-resistant bacteria.

BE-IVA-05: Irreversible Electroporation (IRE) Technique for the Study of Pore Formation in the Lipid Membranes of Giant Unilamellar Vesicles (GUVs)

Recently, a new technique, called irreversible electroporation (IRE) in which an ultra-short pulse with high electric field, has been found to be successful in destroying certain tumor and cancer cells. As a mimic of biomembranes of cells, it is easier to synthesis the lipid membranes of giant unilamellar vesicles (GUVs) of size similar to cells (10 m or more) using the natural swelling method. A high electric field about 320 V/cm or more with a frequency of about 2.5 KHz is applied on a single GUV through the gold coated electrode system. The overall IRE system is contained a MOSFET based electronic circuit where a high electric voltage from 50 V to 600 V with square wave is generated. The electrode system is kept free of chemical effect which shows stability with flexible operating technique. Due to the application of IRE signal on the GUVs, the rupturing is observed in the GUVs for the sake of pore formation in membranes. It is also observed the shape change and membrane fusion of GUVs induced by the IRE signal. The rupture formation of GUVs can be explained on the basis of the classical theory of pore formation in the lipid membranes. The technique may help to understand the mechanism of destruction of the localized cancer or tumor cells induced by IRE technique.

BE-IVA-06: Molecular Transport through a Nano-sized Pore in the Model Membranes Using COMSOL Multiphysics

M. K. Islam, M. A. S. Karal, M. K. Ahamed and S. K. Roy Department of Physics, Bangladesh University of Engineering and Technology, Dhaka-1000, Bangladesh e-mail: [email protected]

Pore formation in model membranes of vesicles induced by peptides, toxics, nanoparticles and electroporation can be observed by the experiment of dye leakage from the inside of vesicles to the outer environment through the nano-sized pores (size 10-20 nm) in the membranes. To investigate the molecular transport through the nano-sized pores in the membranes, at first we have designed a model of single cell with membrane thickness 5 nm and pore size 20 nm in AutoCAD 2D software and imported .dxf file in COMSOL simulation software. We have used the Ficks laws of diffusion with molecular migration, AC/DC and Diluted Species modules in COMSOL Multiphysics. The molecular transport is investigated using various concentration gradients between the inside and the outside of cell and the sizes of pores in a 2D model membrane. The molecular uptake inside the cell varies with the concentration gradients, sizes of pores and the diffusion coefficients. These investigations might be helpful to understand the mechanism of pore formation in the lipid membranes of vesicles and the biomembranes of cells.

Lipid membranes of giant unilamellar vesicles (GUVs) are promising model membranes for investigating the physical and biological properties of biomembranes of cells. GUVs have been extensively used for knowing the interaction of various membrane active agents like peptides, proteins, nanoparticles etc. where purified and similar-sized oil-free GUVs are necessary. Using gravity, we have developed a non-electromechanical technique for the purification of GUVs where the flow rate of buffer containing GUVs suspensions has been controlled by a locally available roller clamp regulator. The technique has been characterized in terms of size distribution, average size, flow rate, quality of recovered vesicles and efficiency. The technique provides the required purified GUVs and it shows the similar results to other technique like membrane filtering method. The new simple and low cost technique can be a future tool for the purification of GUVs in the electricity off condition and therefore can save the power consumption.

Artificially synthesized lipid membranes of giant unilamellar vesicles (GUVs) have been considered as a mimic of biomembranes of cells and therefore lipid membranes have been used for the interactions of peptides,

International Conference on Electronics and ICT - 2018, 25-26 November, 2018 proteins, toxins and nanoparticles. Electrostatic interactions play important physiological roles such as binding of proteins to cell membranes and the structural changes of membranes. Moreover, electrostatic effects destabilize the membranes and hence increase the rate of rupture of the membranes due to external tension. To investigate the electrostatic interaction effects on the size distributions and average sizes of GUVs, at first we prepared 40% dioleoylphosphatidyglycerol (DOPG)/60% dioleoylphosphatidycholine (DOPC)-GUVs in a physiological buffer with various salt concentrations from 0 to 400 mM. Then it was prepared the DOPG/DOPC-GUVs with various ratios of surface charge densities of the membranes by changing the molar ratio of the negatively charged DOPG. Results indicated that electrostatic interaction effects greatly influenced the sizes of GUVs. The binding energy of the membranes at different conditions may be one of the reasons to change the sizes of the GUVs.

IT-VIII: Nanomagnetism as a Boon to Biotechnology

S. M. Hoque Materials Science Division, Atomic Energy Centre, Dhaka

Superparamagnetism or weak ferromagnetic property with zero or limited coercivity is the characteristic of nanomagnetism where exchange correlation length is comparable to the structural correlation length and provide ample opportunity to develop tailored materials. This phenomenon gave rise to different frontiers to revolutionize technology. Biotechnology is one such frontier where nanomagnetism evolved as a boon for mankind. Magnetic separation, targeted drug delivery, radionuclide delivery, gene delivery, cell labelling hyperthermia, magnetic resonance imaging contrast agent, artificial muscle are such ground breaking applications. Thanks to the novel technique of the surface functionalization which provides opportunity of the ferrites to form solutions or colloids. In targeted delivery radio or chemotherapy drug can be loaded onto the surface of the nanoparticles and transported to the targeted location of solid tumor. Superparamagnetic or weak ferromagnetic nanoparticles are potential for the thermal therapy of cancer by themselves. For localized or deeply seated tumor the nanoparticles can be used effectively to destroy tumor cells leaving health cells unaffected by controlling the temperature in the range of 38-46. Further, new emerging fields are gene delivery known as magnetofection, cell labeling, artificial muscle, etc.

A series of yttrium substituted Mn0.3Ni0.3Zn0.4YxFe2-xO4 for x=0.0, 0.02, 0.05, 0.07, 0.10, 0.15 have been synthesized by using conventional double sintering ceramic technique. X-ray diffraction pattern confirmed the single phase cubic spinel structure for studied compositions. SEM micrographs revealed that the grain size decreased up to x = 0.10 and then increased for x = 0.15. The enhanced magnetic properties with the addition of yttrium content compared to the un-doped Mn-Ni-Zn ferrite were noted. The initial permeability shows the 7 frequency independent character up to  10 Hz for all the studied samples. Curie temperature (Tc) was found to be deceased with the increase in yttrium content. The obtained M-H loop revealed higher saturation magnetization (Ms) with due to Y substitutions, may be due to gradual decrease of the Yafet-Kittel angle. The dispersion behavior in the low frequency region was observed in the variation of dielectric constant with frequency curves due to interfacial polarization and became independent of frequency in the high frequency region. A continuous increase in dielectric constant and decrease in resistivity associated with the yttrium doping was also observed. Therefore, yttrium is a promising candidate to optimize both the magnetic and electrical properties of Mn-Ni-Zn ferrites by controlling the physical properties.

In this research, we synthesize and characterize Nb doped LaFeO3multiferroic nanoparticles, LaFeO3 (LFO) which was prepared by conventional solid state method. We investigate their structuraland dielectric properties. Nominal composition of La1-xNbxFeO3 (x = 0, 0.1, 0.2) was prepared from Lanthanum oxide, Iron oxide, Niobium oxide with calculated stoichiometry. Obtained nano-ceramics were annealed at temperature 800ºC following single-stage sintering. Orthorhombic structure of lanthanum ferrite nanoparticles (LaFeO3) with perovskite type phase has been identified from X-ray diffraction (XRD) patterns. The field emission scanning electron microscopy images demonstrated that due to the substitution of Nb, the average particle size was found vary from 50 to 200 nm depending on doping concentration. Dielectric properties of LaFeO3sintered samples were studied in the frequency range 100 Hz–1 MHz. Frequency dependent dielectric constant showed dielectric dispersion behavior. At higher frequencies (≥105 Hz), due to electronic and ionic polarizations only, the dielectric constant is independent of frequency and the dielectric losses found to be decrease with increase of frequency.AC conductivity increased with increase of frequency. Optical band gap slightly increased with increasing doping content. These properties suggested that the doped LaFeO3 ceramic by Nb shows advantage in application over the pure LFO.

In this research, aluminium doped zinc oxide (AZO) thin films in the range of 2% – 8%(atomic) Al content were deposited on glass substrates by the sol-gel spin coating method. To investigate the doping effect of Al on the structural and optical properties of AZO thin films, the films were characterized by using X-ray diffraction (XRD), energy dispersive spectroscopy (EDS), scanning electron microscopy (SEM), and UV–vis spectroscopy techniques. The XRD analysis revealed that AZO films were polycrystalline in nature with hexagonal lattice structure and growth along c-axis. SEM images of the surface of the films exhibited granular nanostructures for lower Al content.It had been observed that the size of the nanostructures decreased for higher Al contents. The film compositional elements zinc, oxygen and aluminum were confirmed by EDS analysis. AZO film containing Al content of 2%(atomic) exhibited higher transmittance around 97% with absorption edge around 385 nm in the visible region. Optical bandgaps were varied in the range of 3.21 - 3.29eV for

International Conference on Electronics and ICT - 2018, 25-26 November, 2018 varying Al content ranging from 2% to 8%(atomic). Noticeable variations of structural and optical parameters with non-linear and non-monotonic changing trend were observed.

Crystalline Sn doped ZnO thinfilms were fabricated on glass substrate by solgel spin coating method. The ZnO was doped with Sn by four different concentrations (2 at%, 4 at%, 6 at% & 8 at%). Various characterization techniques were carried out to investigate the properties of the thin films. From the X- ray diffraction technique, it was revealed that the fabricated films were crystalline structured with c axis orientation. The crystallinity of the films was decreased with increasing Sn content. Thescanning electron microscopy revealed that the gran size of the films was increased with higherthe doping concentrations. All of the films exhibited high transparency level (>85%) in the visible region and a sharp cut off in the ultra violet region of electromagnetic spectrum. The bandgap of the films were also increased with higher Sn concentrations in the film. The obtained bandgaps of the Sn doped ZnO thin films were 3.25 eV, 3.26eV, 3.27eV and 3.30 eV for four different doping concentration respectively (2 at%, 4 at%, 6 at% and 8 at%).The EDS analysis confirms the presence of zinc, oxygen and tin in the film.The observed properties of the films from various investigations reveal its potential for UV sensing device applications.

Multiferroic materials have attracted renewed interest in recent years due to both its potential applications for electronic device and its fascinating fundamental physics. Though, there are very few single phase multiferroic materials, especially room temperature single phase multiferroic materials . Among those single phase multiferroic materials, BiFeO3 (BFO) is the most intensively studied material due to its high ferroelectric Curie temperature TC ∼1103 K and antiferromagnetic Neel

International Conference on Electronics and ICT - 2018, 25-26 November, 2018 temperature TN ∼ 643 K . BFO possesses rhobomhedrally distorted perovskite structure with space group R3c . The magnetic structure of BFO is antiferromagnetic with G-type spin ordering. One of the major drawbacks of BiFeO3 material is the leakage current because of the difficulty in obtaining stoichiometric single phase BiFeO3 materials. Attempts to improve the electrical properties have been made by doping it with rare earth elements such as lanthanum (La), samarium (Sm), gadolinium (Gd), terbium (Tb) and dysprosium (Dy) etc. In the present work, synthesis, electrical and magnetic properties of Eu doped Bi0.9La0.1FeO3 have been studied. Multiferroic Bi0.9La0.1Fe1-xEuxO3 ( x=0,0.02,0.05,0.07,0.10 and 0.15) ceramics were synthesized in solid state reaction route. The effect of Eu substitution on the crystal structure, Permeability and dielectric properties were investigated. The XRD patterns revealed that the substitution of Eu in the place of Fe in Bi0.9La0.1Fe1-xEuxO3 induced a trend of transition from distorted rhombohedral to orthorhombic phase. Lattice parameter were found to be increased with the increase of Eu content till x=0.02 and then almost Constant. Possible reason behind this phenomenon of increasing the lattice parameter might be the substitution of larger ionic radius of Eu3+ (0.947Å) with Fe3+ (0.645 Å). The bulk density decreased upto x=0.02 and then increased with the further increase of Eu content. Dielectric constant (ε´), loss tangent and AC conductivity were measured as a function of frequency at room temperature.

The samples are also annealed in vacuum at 450 oC for 20 minutes and compositional ratio Cu/(Zn+Sn) is found to be 0.81 to 0.65 via energy dispersive x-ray spectroscopy (EDS) analysis.The structural and morphological characterizations of the resulting films were carried out by x-ray diffraction (XRD), and scanning electron microscopy (SEM). The electrical and optical properties were measured by Hall Effect and UV-Vis technique. The change in microstructure with subsequent recrystallization and grain growth was observed with respect to the compositional variation and annealing.The solar cell has been fabricated with an structure of Glass/Mo/CZTS/CdS/i-ZnO/ZnO:Al and metal grid electrodes are formed by thermal evaporation on top of conducting layer. The highest 0.85% efficiency has been achieved so far.

Mobile Phone has converted the world into a global village which is a remarkable contribution of mobile phone in communication and information engineering. After its invention by Motorola Corporation, USA in 1973, it proved to be so useful that it has become a most popular and a part of daily life in modern human technology society. The number of mobile phone uses is increasing day by day and has reached more than 6 billion till today according to ITU. In Bangladesh, also the number is increasing and has exceeded 40 million in 2017. The Electromagnetic radiation (EMR) or Radio frequency (RF) emitted by mobile phone has been named as Non-Ionizing Radiation (NIR). There is general public concern all over the world that the EMR/NIR from mobile phone and tower is harmful for human which affects not only the human but also on living system and environment leading to a great disaster in ecological balance. Scientists of the different countries of the world are doing research and epidemiological studies on NIR and have found a strong co-relation between health problem and microwave radiation from mobile phones and towers. On may31, in the year 2011, the world Health organization (WHO) as per findings of the International Agency for cancer Research (IARC) and recommendation from International Commission on Non-Ionizing Radiation Protection (ICNIRP) has labeled the Mobile Phone (the EMR from Mobile) as a carcinogenic hazard to human health. Mobile Phones and Towers emit Electromagnetic radiation having harmful health effects, which can be divided into two groups; thermal and non-thermal. Non-thermal effects on the cells, genes and the DNA and are more harmful than thermal effects. Excessive use of mobiles can lead to headache, sleep disturbance, lack of concentration, memory loss, tinnitus (ringing in the ears) and increased risk of brain cancer. Having mobile towers in the neighborhood can also pose health problems like severe headache, sleep disturbance, constant body pain, memory problems, joint pains etc. The more severe health effects noted include infertility, miscarriage, neurons generative disorders (Alzheimer’s Parkinson etc), Heart problems and cancer. Many countries of the world have taken

International Conference on Electronics and ICT - 2018, 25-26 November, 2018 precautionary measurements by making laws to protect their citizens. It is a matter of great hope and satisfaction that Bangladesh Govt. has taken steps through BTRC to regulate and monitor the radiation from mobile phone and towers.

Speech refers to the basic verbal means of communicative feature. It consists of articulation voice and fluency. Autism Spectrum Disorder (ASD) is one among pervasive developmental disorders having impairment mainly in social interaction and communication. 40% of ASD population exhibit mutism, may have problems with articulated speech and fluency. Those on the milder end of the spectrum, have normal IQ and well developed language. Though this is an extensively observed issue, acoustic analysis of Bangla speech of speakers with ASD is perceived as an under researched area. Differences in acoustic characteristics between Bangla speech of individuals with ASD whose speaking ability is very low and typically developing controls are investigated. Analyzed acoustic parameters are compared to speech of typically developing speakers of same age group and deviance in acoustic characteristics is observed. Study shows that, the articulatory space area spanned by speech of autistic person is smaller than that of the articulatory space area covered by normal speech of male of same age group.

Fluoro-deoxy-glucose, a radio-pharmaceutical, widely known as FDG used in positron emission tomography (PET) imaging. It is radio-labeled by fluorine-18 resulting from the cyclotron accelerated proton bombardment of highly expensive oxygen-18 enriched water. The produced fluoride-18 solution contains heavy metals and other impurities generated at the time of bombardment with target and metallic target body. After removing all impurities fluoride-18 ion undergoes a nucleophilic substitution reaction with mannose triflate, a derivative of monomer of glucose, and produce crude FDG. Microbial contaminations with other impurities are eliminated before use. This paper reviewed production of FDG by using cyclotron as well as its detailed synthesis process.

International Conference on Electronics and ICT - 2018, 25-26 November, 2018 synthesized by facile hydrothermal method. The ammonium heptamolybdatetetrahydrate, (NH4)6Mo7O24.4H2O (AHM) was used as precursor materials for the MoO3 synthesis. The α-MoO3 nanoparticles were obtained by annealing the h-MoO3 at 450ºC for 2 h. Then, the structural, morphological, functional and optical properties of both h-MoO3 and α-MoO3 nanoparticles were characterized by X-ray diffractometer (XRD), field emission scanning electron microscope (FESEM), Fourier transform infrared spectroscopy (FTIR) and UV-Vis-NIR spectrophotometer, respectively. The X-ray powder diffraction patterns revealed the hexagonal (h-) to orthorhombic (α-) phase transition, the average crystallite size, the intensity and the degree of crystallinity of both samples. The average crystallite size increases to 135.31 nm after the annealing step. The micrograph analysis of FESEM results hasproved the hexagonal rods of h-MoO3 and the layered structure of α-MoO3. FTIR results also reveal the formation of the h-phase sample and of theα-phase sample. Optical studies show that band gap value of 2.83 eV for as-synthesized (h-MoO3) and 2.85 eV for annealed (α-MoO3) samples whichlies in the visible region and thus, it can be an appropriate candidate for visible light photocatalytic application.

Short Message Service (SMS) is one of the most popularly used services for communication between mobile phone users. SMS communication has a general appeal, especially to the youth, because of its flexible use of alphanumeric characters, with little or no regard for orthographical and grammatical rules. This flexibility and freedom poses challenges for translating SMS into formal writing. To overcome this, a pre-processing step known as normalization is required. SMS language has, however, been recognized and accepted as a variant of natural language. Thus, there is compelling motivation to make it possible to build information-based services using SMS communication, through the process of normalizing the various forms in which the language appears. Our aim is to find a suitable technique for normalizing the SMS in a convenient way.

PP-15: 24/7 Power Monitoring, Uninterrupted Power and Internet Service System for ATM Booths of Bangladesh’s Banks.

M. S. Alamgir Department of Electrical and Electronic Engineering University of Chittagong, Chittagong-4331, Bangladesh e-mail:[email protected]

Uninterrupted power and internet service plays an important role for the digitization of Bangladesh. According to Wikipedia there are total 120 Banks in Bangladesh. Each Bank has lots of Branch with lots of ATM booths for money withdraw and deposit bills within and without bank period. Every ATM booth has their own power backup for maximum two or three hours by using online UPS. In our country more than two to three hours power interruption is normal thing due to low power production according to high demand. Due to no electricity monitoring system, it is difficult to understand when electricity has gone and when it comeback so 24/7 ATM booth service is not possible especially at mid night. In this project we develop a remote manual control system by which a IT person can easily monitor power interruption and can start a generator remotely from anywhere before end of UPS power backup.

Precise control of electro hydraulic actuator (EHA) may become an indispensable task due to its high nonlinearities and uncertainties. This paper presents a psycho-biological motivated adaptive control featured by emotional learning mechanism: a brain emotional learning based intelligent controller (BELBIC), to control the trajectory of the electro hydraulic actuator. The control signal generated by this computationally efficient controller consists of an adaptive control signal to compensate the uncertainties and handle the nonlinearities. During operation, it tries to keep the trajectory error of the EHA as minimum as possible corresponding to a random disturbance. Experimental results have been carried out to evaluate the performance compared to conventional PID controller and fuzzy-PID controller.

The food quality can be influenced by many factors and one of them is certainly the level of radioactivity, especially after nuclear emergency situations, such as the Fukushima-Daiichi accident. Detailed knowledge of the activity concentrations of radionuclides in foodstuff is necessary to determine the effective dose to the population from the food chain, since the ingestion of food is the most significant route of radionuclide intake for the public (ICRP, 1992). The objective of this study is to assess the level of radioactivity in different food samples imported from SAARC and other countries as a part of radioactivity monitoring surveillance program. During the two fiscal years from 2015- 2016 to 2016-2017, total 86 imported food samples were collected from local market viz. Noya bazaar, Dhaka; Hatirpool bazaar, Dhaka and Kachpoor bazaar, Narayanganj etc. Different Food samples such as Anchor Dal, Dabli, Ginger, Garlic, Rice, Red Wheat, White Wheat, Lentils, Chhola, Palm Oil and Soybean oil were imported from different countries such as Australia, China, India, Pakistan, Maldives, Malaysia and Nepal. This kind of study is required for Import Policy Order 2015- 2018 under Ministry of Commerce. The gamma spectrometric measurements on samples were carried out using a high-purity germanium (HPGe) detector with a high-resolution HPGe coaxial detector with a relative efficiency of 19.6% coupled with a Digital Spectrum Analyzer (DSPec jr 2.0). The radioactivity range of 232Th series are found to be (0.19 – 80.87) Bqkg-1 and that of 238U series are found to be (0.33 – 63.098) Bqkg-1. The radioactivity range of 40K is found to be (239 - 687) Bqkg-1. No artificial radionuclide was observed in these analyzed samples.

The infliction of radiation protection of workers through individual monitoring system is the major part of the condition for using ionizing radiation devices which has been imposed by ICRP-2007 and IAEA GSR part-3. The National Law of Bangladesh demands that all workers, working under ionizing radiation, should be monitored by Thermoluminescent Dosimeter (TLD). The aim of this work is to analyze annual effective dose rate for the consecutive 4 years in the field of radiotherapy and diagnostic X-ray. The assessment was done quarterly in each year by TLD-100 badge which has been read out using TLD reader HARSHAW 4500. During these years, the workers, working in the field of radiotherapy, have been more exposed than the workers in the area of diagnostic X-ray. In addition, the annual effective dose in both fields is lower than minimum detection level (MDL) which indicates that occupational exposures are well below the limit set by the NSRC Rules 1997 of Bangladesh and GSR part-3 of IAEA.

As per requirements of Bangladesh Atomic Energy Regulatory Act-2012 and Nuclear Safety and Radiation Control Rules (NSRC)-1997, it is essential to do workplace monitoring at Atomic Energy Centre Dhaka (AECD) to protect occupational workers from ionizing radiation. Five divisions of AECD, viz. Non Destructive Testing (NDT), Accelerator Facilities Division (AFD), Material Science Division (MSD), Chemistry Division and Health Physics Division (HPD) have been using radioisotopes and radiation producing equipments for research & development works. Radiation monitoring has been done on monthly basis in and around the above mentioned divisions by using digital survey meter GAMMA SCOUT. The Gamma-Scout hand-held radiation detector or geiger counter is a general purpose survey meter for measuring and detecting ionizing radiation, it can detect alpha, beta, gamma and x-ray radiation. During the last two fiscal years from 2016-2017 to 2017- 2018, the radiation levels in front of isotope storeroom (corridor) of HPD, Source room (corridor) of HPD, NDT Source storeroom and in front of door of NDT source room were found (0.40 - 2.5) µSvh- 1, (0.23 – 0.56) µSvh-1, (0.22 – 15.00) µSvh-1 and (0.18-0.24) µSvh-1 respectively. The control panel of AFD, XRD room of MSD and EDXRF room of Chemistry division were found around background level. It was observed that except NDT Source storeroom, the dose level remain within recommended dose limit set by NSRC Rules-1997 of Bangladesh and International Atomic Energy Agency (IAEA) Safety Standards- General Safety Requirements (GSR) Part 3.

Cr substituted Co-Zn ferrites having the chemical formula Co0.5Zn 0.5Fe2-x (x =0.0, 0.1, 0.2, 0.3, and 0.4) were prepared by the solid state reaction method. The samples were characterized using X-ray diffractometer (XRD), Scanning Electron Microscope (SEM).Dielectric and Magnetic properties of the samples were also investigated. The XRD pattern indicates the formation of single-phased cubic spinel structure.The lattice parameter, density and porosity were calculated for all the samples. The SEM images exhibit that the average grain size reduces and then increases with higher substitution of Cr.The permeability decreases upto 0.2 then gradually increases for further doping concentration which is co- related of the grain size of the samples. The loss factor increases with increase in Cr content but except at x=0.3. Relative quality factor (RQF) is maximum for x=0.1 which indicates, better application value at high frequencies. Generally, the dielectric constant and dielectric loss increases with increase in Cr content. The sample for x=0.3 dielectric constant is maximum and permeability value is high, which indicatesthis sample as a single phase multiferroic material. RQF is also satisfactory for all the samples and it is equally applicable for the both low and high frequency devices. The result indicated that the substitution of Cr significantly influenced the structural, dielectric and magnetic properties of Co-Zn ferrites.

Thermoluminescent dosimeters (TLDs) have three major uses; as personal dosimeters for people who work with or around radiation, environmental monitoring around nuclear installations, and for verifying the radiation doses given to radiation patients. The purpose of this work is to compare the response obtained with the TLD chips of TLD 100 and TLD 700 with β-γ irradiation. The TLD 100 and TLD 700, due to presence of difference in the concentration of isotopes of Li, are abundantly used to obtain the information of radiation dose such as gamma and beta. In the present study, TLD reader (Harshaw Model 3500) was used to readout the samples in a flowing hot N2 gas to reduce surface oxidation. During readout pre-heat temperature was set initially at 50˚C, acquired temperature rate 10˚C/s, to maximum anneal temperature of 300˚C. Response of TLD-100 and TLD-700 under varying dose from 1.4 to 7.0 mGy was compared. In this work thirty TLDs of two different types was used: TLD 100 and TLD 700. The TLDs were irradiated in an experimental setup using a Sr-90/Y-90 irradiator. The composition of the dose in different types of TLDs was evaluated for dosimetric properties focusing on linearity and reproducibility. It was found that the response of TLD 700 is 1.2 times greater than that of TLD 100 and the reproducibility tests made on two types of chips were found satisfactory.

Multiferroic Composites (1-x)BaTi0.5Mn0.5O3-(x)Ni0.6Zn0.4Fe1.85Sm00.15O4 ((1-x)BTMO-(x)NZFSO) with x = 0.0, 0.2, 0.4, 0.6, 0.8, 1.0 have been synthesized by the conventional solid state method. The structural property was studied by X-ray diffraction (XRD) method. The XRD patterns indicate the formation of well crystallized simple cubic structure of NZFSO and BTMO phases in the composite powders and ceramics with a small contribution of secondary phase. The intensity peaks of the secondary phase increased with the increase of Sm3+ content. The secondary phases were identified as SmFeO3. The lattice parameter was calculated by plotting of N-R function for all samples. The lattice parameter and volume were increased with increasing Sm3+ content. X-ray and bulk density followed similar trend in variation and inverse relation between bulk density and porosity was noted. The porosity produced during sintering process caused to decrease the bulk density compared to X-ray density. The Enhancement of magnetic properties was observed for the multiferroic composites with increase in ferrite concentration, NZFSO. The saturation magnetization (Ms) and anisotropy constant (K) were increased with increase in NZFSO ferrites while the coercive field (Hc) was decreased. The highest values of coercive field ⁓ 153.395 Oe and the saturation magnetization ⁓ 5.25 emu/g were noted for x = 0.0 and 1.0 compositions, respectively.

The effects of different doping concentration on the structural, morphological and optical properties of the Sn doped CdSe films are studied. The thin films of undoped CdSe and 5%, 10% and 15% Sn- doped CdSe have been grown on glass substrates by chemical bath deposition technique. X-ray diffraction patterns revealed cubic phases for the grown of CdSe thin films. Thickness of all samples were measured and found near 203 nm. The lattice parameter, crystallite sizes were determined from X-ray diffraction patterns. The optical measurement of transmittance and band gap of these films were determined using UV-Vis Spectrometry. FTIR spectra indicates the successive formation of CdSe films with different concentrations. CdSe has poor intrinsic conductivity and doping can help to achieve maximum effectiveness of CdSe thin films.

The structural and magnetic properties of Ca, Sr and Mn doped ferroelectric Barium Titanate (BaTiO3) with the general formula Ba0.4Ca0.4Sr0.2MnxTi1-xO3 (where, x= 0.0, 0.05, 0.10, 0.15, 0.20) have been synthesized by solid-state reaction technique. In this study Barium Titanate is doped with manganese at the B-site and calcium, strontium at the A-site of the lattice. X-ray diffraction (XRD) and vibrating sample magnetometer (VSM) measurements were used to study the divalent substitutions and their impact on the crystal structure and magnetic properties of the BaTiO3 ceramics. X-ray diffraction patterns of the samples indicated single phase cubic perovskite structure. The lattice constant was calculated and found to decrease with increasing Mn contents due to smaller ionic radius of Mn2+ (0.80 Ȧ) compared to Ti4+ ( 1.47). The density of the samples was found to increase with contents (x = 0.0 to 0.10) and slightly decreased for higher Mn contents (x = 0.15, 0.20) while the porosity decreased with Mn contents (x = 0.0 to 0.10) and slightly increased for higher Mn contents (x = 0.15, 0.20). The magnetic hysteresis loop was obtained from VSM measurement at room temperature. The cocerivity (Hc), saturation magnetization (Ms) and remanent field were calculated for different Mn contents. The saturation magnetization for Mn substituted compositions was found to have higher values than the un-substituted one.

Ceramic materials with a perovskite structure are very significant electronic materials because of huge applications in microelectronics, electro-ceramics and advanced technology system. BaTiO3 ceramic has been successfully used in PTC thermistors, piezoelectric devices, actuators, sensors, ultrasonic transducer, underwater devices, high temperature heating applications, frequency ﬁlters for wireless communications etc. The properties of BaTiO3 can be tuned by dopant incorporation. In this research work Sr and Al are substituted in BaTiO3 with general chemical formula Ba0.7Sr0.3Ti1-xAlxO3 in the range of 0≤ x ≤0.2 where, Sr is substituted at A-site with Ba in a fixed molar ratio of 0.3 and Al is substituted at B-site with Ti in 0.05 molar steps. The samples were prepared with standard solid state reaction method. The specimens were pre-sintered at 700oC for 4 hours and sintered it at 1150oC for 4 hours. The physical, microstructural and magnetic properties were characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) and vibrating sample magnetometer (VSM) system. It was observed that the samples are in single phase simple cubic perovskite structure without any impurity peak. From the SEM images it was observed that the grain size was increased at first for the sample with Al content x = 0.05 and then decreased with further increase in Al content. It is observed from the VSM experiment that all the compositions exhibit ferromagnetic properties at room temperature. The value of magnetization, coercive field, remnant magnetization, anisotropy constant has been increased because of Sr and Al substitution. The frequency dependent permeability was determined by impedance analyzer show that cut off frequency is shifted towards high frequency with increase in Al content.

Barium titanate is the first ferroelectric ceramics and a good candidate for the variety of applications due to its excellent dielectric, ferroelectric and piezoelectric properties. The Zr substituted on Ba1- xZrxTi0.98Y.02O3, (x = 0.0, 0.02, 0.05, 0.07 and 0.1) ceramics were synthesized by solid state reaction technique. The phase analysis of (Ba1-xZrxTi0.98Y.02O3) ceramics was done by XRD technique. The structural parameters such as lattice constant, bulk density, x-ray density and porosity were calculated from XRD data. The variation lattice constant was explained in terms of ionic radius of substituted and substituting ions. The values of bulk density and porosity for different Zr contents exhibited a good anti-correlation. The bulk density is lowered than the x-ray density due to pores developed during sintering. The magnetic properties were obtained from VSM measurement. The saturation magnetization, coercivity, remanent magnetization and Bohr magneton were calculated from the hysteresis loop. The saturation magnetization was found to be decreased due to Zr substitution.

Ferrites with basic chemical composition of Ni0.6Mn0.2Zn0.2CrxFe2-xO4 (where x = 0.0, 0.05, 0.10, 0.15 and 0.20) were synthesized by double sintering method from the oxides of Ni, Mn, Zn, Fe and Cr. The structural and electrical properties of the ferrites have been investigated using X-ray diffraction (XRD), DC resistivity and dielectric properties measurements. The cubic spinel structure has been confirmed by the XRD analysis with an extra intermediate phase. The structural parameters such as lattice constant, X-ray density, bulk density, porosity have been calculated for the samples and explained using established formalism. The lattice constant has found to decrease with the addition of Cr owing to smaller ionic radius of Cr (0.615 Å) than that of Fe (0.645 Å) ions. DC resistivity as a function of temperature has also been measured. The semiconducting nature has been found to be operative in the samples. The activation energy has been calculated and is found to be associated with resistivity values. The DC resistivity was found to decrease while the dielectric constant increased with increasing Cr content in the Ni-Mn-Zn ferrites.

This report focuses on the structural and magnetic properties of Co substituted Ni0.65-xCox Zn0.35Fe2O4 with x = 0.00, 0.01, 0.03, 0.05, 0.07, 0.09, 0.10. The samples of Ni0.65-xCox Zn0.35 Fe2O4 were prepared by the standard solid state reaction method. The samples were sintered at 1300oC and 1350°C in air for 3 hours. The single phase spinel structures of the studied samples have been confirmed by X-ray diffraction. The lattice parameter is gradually increased as the Co content due to larger ionic radii of Co (0.745Ao) compared to Ni (0.69Ao). Microstructural study done by FESEM revealed enhancement of grain size with Co substitution. The saturation magnetization, Ms and initial permeability, μi increase as the Co content is increased. The magnetization enhancement have been associated with the 2+ 2+ higher magnetic moment of substituted Co (3μB) for Ni (2μB). But the sharp increase of permeability μi from around 50 for x =0 to 925 for x= 0.1 is connected with the compensation of magnetostriction coefficient having positive for Ni-ferrite and negative for Co-ferrite. However, the enhanced permeability of Co substituted Ni-Zn ferrite resulting from larger grain size and higher magnetization value may also have positive impact.

All the samples showed a maximum sharp peek at an angle 18.6017 and the plane (113).From XRD analysis, it was revealed that X-ray density decreases with increasing Al- concentrations.Whereas, the bulk density and lattice constantvaried with differentAl contents.The minimum porosity(19%) obtained without Al properties examined by the VSM. All the samples reached at maximum saturation magnetization around the same applied magnetic field. Thesaturation magnetization increased with Al- doping but varied with different Al concentrations.

Ni Zn ferrite with spinel structure are being extensively used in a number of electronic devices due to their tremendous high electrical resistivity, low magnetic coercivity, mechanical hardness, chemical stability and reasonable cost. Ni0.6-xZn0.4SrxFe2O4 with x=0.0, 0.05, 0.10,0.15 and 0.20 have been synthesized by the conventional solid state method. In this study Ni was doped with Sr at the A-site of the lattice. The phase analysis of Ni0.6-xZn0. 4SrxFe2O4 was done by X-ray diffraction (XRD) technique. The XRD pattern indicate the formation of simple cubic structure with a small contribution of secondary phase. The secondary phase was noticeable in three samples (x=0.10, 0.15 and 0.20). The lattice parameter was calculated by plotting N-R function for all samples. The lattice parameter and X- ray density were increased with increasing the concentration of Sr2+. An inverse relation between X- ray density and bulk density noted. The values of bulk density and porosity for various Sr content also showed an anti-corelation. The magnetic properties were obtained from vibrating sample magnetometer (VSM) measurement at room temperature. The coercivity (Hc), saturation magnetization (Ms) and remanent field were calculated for various Sr content. The saturation magnetization for Sr substitution was found to have maximum value for x=0.0 content.

On-line shopping system is very much demanding issues in current era of Internet. Consumers are demanding the different issues related to on-line shopping. In this paper, an online shopping system has been designed, developed and implemented that permits a customer to submit an on-line order for items and/or services from a store that serves both walk-in customers and online customers. The online shopping system presents an online display of an order cut off time and an associated delivery window for items selected by the customer. The system accepts the customer's submission of a purchase order for the item in response to a time of submission being before the order cut off time. This shopping system does not settle with a credit supplier of the customer until the item selected by the customer picked from inventory but before it is delivered. It provides detailed information about various products in different categories and deals with the customer by making an agreement. This system is an automated web based application system that provides the advantages such as saving the time, facilitating to buy product at anytime from anywhere. The administrator can update their products through database and maintain relationship with customers by sending information about new products and different types of offers through email at any time.
