Abstract: In this study, Cadmium Sulphide (CdS) thin films are deposited on glass substrates by means of Spray Pyrolysis method to examine the influence of electromagnetic and optical features of these films by diode laser . Accordingly, samples are feasibly irradiated by laser pointer with a power of 500 mw and a wavelength of 532 nm at distance of 10 cm from the source during dissimilar exposure times of 10,20,30,40,50,60,70 and 80 minutes. The absorbance spectrums has been measured by UV-visible spectrophotometer under range of 190-1100 nm .Optical parameters such as transmission , reflection ,absorption coefficient (α), extinction coefficient (K), optical band gap (Eg), refractive index (n), and complex dielectric constants were evaluated from absorbance spectra. The results shows that the laser pointer irradiation cause decreased in transmittance (T), reflectance (R), absorption coefficient α, the extinction coefficient (K), refractive index (n) and the real and imaginary parts of dielectric constant and decrease in the value of the energy gap (Eg). In study of FTIR-spectrum of CdS films in different ratio of irradiation times, there was no change in the peak positions just bigger or smaller with increase in times of irradiation.
Keywords: Thin Film, Cadmium Sulfide (CdS), Spray Pyrolysis, Laser Irradiation, Electromagnetic and Optical Properties.

Grain and hetero interface growth mechanism of CuO/ZnO photocatalyst composite
M Marina§, M Z M Zamzuri§, Z Nooraizedfiza§, K Alir§, A S Syazwani§ and M Izakiɸ §School of Manufacturing Engineering, Universiti Malaysia Perlis, 02600 Pauh Putra, Perlis, Malaysia ɸDepartment of Mechanical Engineering, Toyohashi University of Technology, 1-1 Hibari Gaoka, Tenpaku, Toyohashi, Aichi 441-8580, Japan

Abstract: Investigations on the grain and hetero interface growth of CuO/ZnO photocatalyst composite by thin film synthesis on fluorine doped tin oxide (FTO) glass substrates by sol-gel technique has been ventured. The coated substrates were annealed at three different temperatures; 300, 400 and 500°C. The grain size and compounds distribution were evaluated by SEM and EDS analysis. Structural properties were characterized by XRD analysis. Thin film synthesized with 500°C annealing temperature exhibits the best grain formation evaluated by the average size, uniformity of the grain grown and smooth interface buildup. Findings proposed that annealing temperature plays a significant role in tuning the end properties of the composite film. SEM observations found uniform grain growth in the 500°C composite film. The finding is further supported by EDS analysis showing the presence of oxygen in the film is low which is preferred, as high content of oxygen will deteriorate the end properties. XRD analysis reported that nanosized crystals were grown with the average size of 250 nm for CuO and 266 nm for ZnO. Low c/a ratio also suggested that the high temperature annealed sample has higher bandgap, and this will boost the hetero interface between the two semiconductors. On the other hand, the bandgap enhancement is measured on 400°C specimen with lowest c/a crystal structure ratio. The findings suggest that annealing temperature plays a vital role in determining the grain and hetero interface formation of the composite and the role of the yielded CuO monoclinic structure in bandgap tuning of the thin film.

S Aati and S Nejim Automatic Control & Marine robotics Research Unit, Naval Academy of Tunisia, 7050 Menzel Bourguiba, Tunisia.
Abstract: Nowadays, Computational Fluid Dynamic (CFD) analysis is one of the most affordable techniques to determine the aerodynamic characteristics of an aircraft. It allows a development of advanced flight controllers. However, the accuracy of this technique depends on the input parameters such as the solid model. This paper describes a methodology to estimate aerodynamic derivatives of a Cessna 182 aircraft based on solid model established by using photogrammetry technique. 312 images have been taken using Canon D750 camera with a 24 mm lens. A dense point cloud of the aircraft was generated using MicMac photogrammetry software. Then, the aircraft 3D-geometry was extracted in order to create the CAD model. Afterwards, parameters such as lift and drag coefficients were estimated at different angles of attack using Ansys Fluent software. The simulation results show that the lift and drag increase up to stall angle, then the lift starts to decrease. These results matches the theoretical ones.
Keywords: Photogrammetry, 3D modeling, CFD, Aerodynamics, Ansys.

Abstract: The development of baseline energy models and prediction of energy consumption in educational buildings especially universities are heavily depending on its operation period. The main operation period can be divided into two period i.e. lecture week and non-lecture week. Possible independent variable candidates that may have an effect towards energy consumption during this two period differ with each other. In addition, spaces that occupies the educational building such as classrooms, laboratories and office rooms within the same building operates differently depending on its operation period. In order to achieve accurate baseline energy models in educational buildings, the operation period have to be considered based on the independent variables that will have an effect towards the energy consumption. Thus, the twofold objectives of this paper are to develop a baseline energy model for two operation period in educational buildings and predicting the energy consumption using multiple linear regression model. One building in a university compound was selected as a case study for modelling and prediction purposes. Independent variables were selected based on the two- period mentioned and from the modelling and prediction results, the independent variables that were selected gives a high coefficient of correlation (R2) value which suggest that the independent variables effect the educational building’s energy consumption.

Abstract: Workplace noises, such as realistic environmental and occupational noises, routinely take place in the work environment and have been linked with negative cognitive effects. Little is known about their impact on brain activity during mental stress. The current study aimed to investigate the effects of workplace environments, quiet and noisy, on brain activity and mental stress in the prefrontal cortex (PFC) using functional near-infrared spectroscopy (fNIRS). The results found that cortical activation level of HbO for quiet workplace was greater in the dorsolateral prefrontal cortex (DLPFC) and part of frontopolar area (FPA) compared to noisy workplace. The results also revealed a classification accuracy of about 91.07 % in the discovery of noisy workplace group using support vector machine (SVM). These approaches using fNIRS together with a knowledge of the effect on human may possibly lead to improved performance by optimizing working environments.

Abstract: A considerable amount of energy is lost by utilizing the traditional pulse width modulation (PWM) based inverters in an on-grid PV system. Therefore, a model predictive current control (MPCC) based control strategy is proposed in this research work. The controller works based on a predefined cost function. The cost function includes deviation of current from its reference and a switching frequency term to reduce the average switching frequency. All the possible control actions i.e. inverter switching states are tested against the cost function. The state which yields minimum cost is selected as an optimal control action for the inverter. Simulation results show that the proposed controller tracks the reference current accurately with a mean absolute error of 2.5% which is 30% for the PI-PWM based controller. The MPCC based inverter yields low current THD of 2.07%, whereas in traditional PI-PWM based inverter the current THD is 7.26%. The energy efficient operation of the MPCC based inverter is also verified by doing loss analysis. It is shown that conduction, switching, and harmonic losses of the inverter are reduced by 36.8%, 50%, and 91.9%, respectively, in comparison with the PI- PWM based inverter.

Combination effects of fault resistance and remote in feed current on simple impedance based fault location
Muhd Hafizi Bin Idris School of Electrical System Engineering, Universiti Malaysia Perlis, Pauh Putra Campus, 02600 Arau, Perlis, Malaysia.
Abstract: There are many types of fault location algorithms and one of it is simple impedance based fault location algorithm which is still widely used by power system utilities around the world mainly because of no communication channel exists between local and remote substations. The aim of this research is to study the combination effects of remote infeed current and fault resistance on the accuracy of simple impedance based fault location algorithm which is used to estimate fault location when the transmission line is connected to equivalent Thevenin sources from both ends. Simulation has been carried out using Matlab Simulink software for single line-to-ground fault and line-to-line fault. For each type of fault, fault location and fault resistance were varied for two conditions which were when remote breaker in open and remote breaker in close conditions. From the results, it can be concluded that remote infeed current will add additional error to the error due to the existence of fault resistance when fault resistance not equal to zero.

Abstract: Time domain (TD) features are frequently used for surface Electromyography signal (SEMG) pattern classification paradigm because they are computationally simple and easy to execute. In addition, TD features are extracted without the need for transformation directly from the raw data. Numerous TD features have been utilized as reported in the literature in the extraction of SEMG features. Some of these features, however, are not useful and make the feature vector redundant. Therefore, before the classification phase, it is essential to pick a subset of salient features from the initial function set. In this study, the combinations of two and three TD features were evaluated using an essential statistical method. This technique is; the RES index was called the relationship between Euclidean distance (ED) and Standard deviation (SD). While the ED measures the distance between two scatter groups (two joint ankle movements), the Standard (SD) measures the difference between each scatters group. This method was implemented for data from the shank muscles on the SEMG signals measured. The findings showed that the combination of the features of logWL and logSD outperforms the other combination features chosen for TD.

Abstract: In recent years, many studies have emerged about regarding the topic of school failure, showing a growing interest in determining the multiple factors that may influence it [1]. Most of the researches that attempt to solve this issue [2] are focused on determining the factors that most affect the performance of students (dropout and failure) at the different educational levels (basic, middle and higher education) through the use of the large amount of information that current computer equipment allows to store in databases. All these data constitute a real gold mine of valuable information about students. But, identifying and finding useful and hidden information in large databases is a difficult task [3]. A very promising solution to achieve this goal is the use of knowledge mining techniques or data mining in education, which has resulted in so-called Educational Data Mining (EDM) [4]. This new area of research is concerned with the development of methods for exploring data in education, as well as the use of these methods to better understand students and the contexts where they learn [5].

Abstract: There is a fast increase of information and data generationin virtual environments due to microblogging sites such as Twitter, a social network that produces an average of 8,000 tweets per second, and up to 550 million tweets per day. That's why this and many other social networks are overloaded with content, making it difficult for users to identify information topics because of the large number of tweets related to different issues. Due to the uncertainty that harms users who created the content, this study proposes a method for inferring the most representative topics that occurred in a time period of 1 day through the selection of user profiles who are experts in sports and politics. It is calculated considering the number of times this topic was mentioned by experts in their timelines. This experiment included a dataset extracted from Twitter, which contains 10,750 tweets related to sports and 8,758 tweets related to politics.

Abstract: In higher education, student dropout is a relevant problem, not just in Latin America but also in developed countries. Although there is no consensus to measure the education quality, one of the important indicators of university success is the time to graduation (TTG), which is directly related to student dropout [1]. Global estimates put this dropout rate at 42% [2]. In the United States, this rate is around 30% and represents a loss of 9 billion dollars in the education of these students [3]. However, desertion not only affects the quality of education and the economy of a country, but also has effects on the development of society, since society demands the contributions derived from the population with higher education such as: innovation, knowledge production and scientific discovery [4]. Using basic statistical learning techniques, this paper presents a simple way to predict possible dropouts based on their demographic and academic characteristics.

Abstract: Indicators are the most important management tool for environmental monitoring. Environmental indicators condense the information and simplify the approach to environmental phenomena, which are often complex, and makes them very useful for communication. The usefulness of these indicators consists of providing relevant information, summarized in the form of concise and illustrative statements for decision making, both for the organization’s management and for the rest of the members. The prediction of limit values, together with the potentialities offered by the recommendation system based on ontology make this system a powerful tool for supporting decision- making in the Environmental Management process with a wide possibility of generalization in the business sector.

Abstract: This paper investigates the influence of different magnetization patterns on the performances of the surface-mounted permanent magnet synchronous machines (SMPMSMs). Three magnetization patterns are employed, which are radial, parallel, and ideal Halbach magnetizations. These magnetization patterns are applied to 9-slot/10-pole and 15-slot/4-pole permanent magnet (PM) machines. The PM machines are designed and simulated by using Opera 2D finite element. The performances of three PM motors, such as airgap flux density, phase back-EMF, and cogging torque, are evaluated under the influence of different magnetization patterns. The total harmonic distortion of phase back-EMF (THDv) for the motors are investigated. The PM motors with ideal Halbach magnetization provide the lowest cogging torque and the lowest total harmonic distortion of phase back-EMF. Besides that, the optimum setting of the magnet pole-arc can reduce the total harmonic distortion of phase back-EMF and achieve lower cogging torque. The optimum magnet pole-arc produced by radial magnetization in 9-slot/10-pole motor is 24.8° mech., with cogging torque of 0.45 Nm, and THDv of 2.69 %. Meanwhile, the optimum magnet pole-arc produced by parallel magnetization in 9-slot/10-pole motor is 26.0° mech., with cogging torque of 0.41 Nm, and THDv of 2.00 %.

Abstract: Partial discharge (PD) often begins with cracks or gas-filled voids in solid insulation or with gaseous bubbles in liquid insulation. These presences can degrade the quality of insulator. PD detection can identify these cracks at high voltage equipment such as power cables and power transformer at the early stage. One of PD detection methods is acoustic emission (AE) detection. PD produces an ultrasonic signal that can be captured by an AE sensor. The signal captured is then analysed by capturing the time of the receiving signal onto the sensor. The information related to time can be used for allocating the PD for maintenance purpose. This paper shows the influence of the distance between PD source and the AE sensor towards the arrival time of propagation wave in power transformer. In this study, the four placements of sensors were analysed by having three possible PD sources to represent the variety of distances between the PD source and the sensor. The simulated signal is generated by MATLAB and the arrival time is captured using time of arrival (TOA) method. The time captured and the distance between the PD source and arrival time showed that the relationship is proportional to one another.
Keywords. Partial discharge, AE sensor, arrival time, PD source, propagation wave.

I E Lee, G C Chung, W L Pang, S S Anas and M Y Cheong Faculty of Engineering, Multimedia University,Cyberjaya, Malaysia.
Abstract: The continuous development of online social services and the ever-increasing number of devices demanding high-speed and ubiquitous broadband wireless access have resulted in severe bandwidth congestion, such that the radio frequency (RF) spectrum will no longer be able to support the exponential growth in demand. Along with being faster, cheaper, greener, cleaner, and safer than current technology, visible light communication (VLC) can overcome the bottleneck issues with last- mile connectivity by offering 10,000 times broader bandwidth. In this paper, we propose a system with portable, low-cost hybrid RF/VLC and free-space optics (FSO) transceivers with a simple graphical user interface and the capability of indoor wireless communication and multimedia broadcasting, thus presenting an economical and cable-free solution to various multimedia applications, such as file transmission and real-time audio and video streaming. The proposed system deploys VLC as a hotspot for data broadcasting within an enclosed room, FSO as the backbone for data transmission between multiple rooms, and Wi-Fi for lights-off mode. Preliminary results show a transmission rate of 1kbps at a maximum distance of 4 cm.

Abstract: Modelling solar cell involved the formulation of the current versus voltage (I − V ) non-linear curve. Obtaining the accurate model parameters value is important for better performance evaluation, simulation and control of solar cell and module. Extracting these values using traditional methods required more resources, therefore, the used of metaheuristic optimization method become attractive choice. Some optimization algorithms have been used to estimate the model parameters. However, more investigation is needed to improve model estimation. In this paper, the performance of Animal Migration Optimization (AMO) technique in identifying the unknown parameters of solar cell double diode model is studied. A measurement data of a 57 mm diameter commercial (R.T.C. France) silicon solar cell is used to observe the performance of this algorithmand the consistency of accurately estimating various parameters. The results show that the estimated and experimental data are accurately fitted and certify a good agreement. Furthermore, comparative study among different parameter estimation techniques is presented to demonstrate the effectiveness of the proposed approach.

Abstract: This paper discusses the level of harmonic distortion in current power distribution system for laboratory and office building. These two places often house a significant number of equipment such as computers, air conditioners, etc which are significant nonlinear loads. The high number of these nonlinear loads affects the quality of the power system and energy at the linked grid. This is due to harmonics components in current that is resulted by the conversion and switching processes by the nonlinear loads. This case study is located at main operation buildings at School of Electrical System Engineering, Universiti Malaysia Perlis at Pauh Putra Campus. This case study is intended to study the severance level of harmonics in current distortions at the said power distribution system. The tool used for data mining and analysis is the Fluke 1750, which records the data for 30 days. The analysis includes the level of harmonics in current at the point of common coupling at the power distribution system. It is benchmarked against relevant standards related to harmonics in current and power quality in grid. It is found that the harmonic distortion level exceeded the maximum value set by standards. This highlighted that the quality of power at this grid is low and results in losses of energy.

Abstract: The High resistance grounding was used at the oil and gas platforms because of the main reason not to have the process in the facility interrupted. There are cases where main high voltage contactor have tripped and disabled the process at satellite platforms due to the lightings module grounded. This is unacceptable to the daily production. In this paper it will discuss on the electrical distribution load flow analysis, capacitive charging system for the HRG designs and the single phase to ground fault control which offers by the HRG systems. In the oil and gas platform, there are always a case where the ground fault occur and causing disturbance to the process. With the 3 Generators (Solar Centaur 3125 MVA) power for the overall electrical distribution, all the equipment on the buses are prone to the faults. It has always been the challenge to control and eliminate or reduce the ground faults. The determination of the total system charging current (Ic) is important and thus determining the value of resistor that able to limit the fault to ground. The limit of current is about 5-10A. This investigation also will compare and analyze the line to ground faults. Symmetrical components are usually widely used for the study of fault calculations

Abstract: The health and productivity of a given plant depends on several factors. Two of these factors are the amount of water and nutrients received by the plant. Too little or too much of these may drastically affect the health and productivity of the plant. Thus, a system that constantly monitors the moisture level of a given crop and irrigates the crop to maintain an optimal moisture level in the soil for that crop was developed. A modular, top-down methodology was used to develop the software which was implemented on an Arduino Uno microcontroller. The system continuously monitors the soil’s moisture levels and open or close the valves that control the water flow to the crop.

Abstract: Nowadays, demand for electricity is increasing every single day. This is due to the deep requirements in current economy. Generating electricity is an important element to ensuring a system operates in good condition and not being affected. At the same time, some problems have arisen as a phenomenon of transient stability. Hence, analysis needs to be done to control energy stability in rivalling current demand. Power system stability can be further divided into 3 sub-analysis starting with rotor angle stability which is the ability of synchronous machines of an interconnected power system to remain in synchronism after being subjected to a disturbance, voltage stability which is the ability of a power system to maintain steady voltages at all buses in the system after being subjected to a disturbance and also frequency stability which the ability of a power system to maintain steady frequency following a severe system disturbance resulting in a significant imbalance between generation and load. This analysis is used the IEEE Bus System 14 and analyzed using Power World Simulator (PWS) software. The variations in power angle, bus voltage and system frequency were studied with the help of three-phase balanced fault. Fast fault clearing times were analysed for a three- phase balanced fault in order to re-establish the stability of the system. Furthermore, impact of fault location on system was also computed to observe whether it affected the stability of the systems.

Abstract: This project presents the development of power generation energy by using piezoelectricity effect. The wasted mechanical energy from walking can be converted to electrical energy by using a piezoelectric transducer and can be stored in a battery for later use. The main idea is to construct a power generation system, which includes the piezoelectric transducers as renewable sources that can be used to power up low power application. The piezoelectric transducers are able to produce electrical charges by stressed when subjected to dynamic strain (expand). Three circuits used to improve this project were voltage multiplier circuit, charge controller circuit, and LCD display DC voltage output circuit. Voltage Multiplier circuit was the main circuit that used to convert from AC main power supply generated from the piezoelectric sensor to DC supply as the output. The piezoelectric sensor regulated DC voltage output and charged the rechargeable battery. The basic Arduino coding was used to display DC voltage from the battery to easily know and predict the output voltage from the piezoelectric transducer to do the analysis. The 16 V maximum voltage already taken out from this piezoelectric circuit was enough to charge a 7.4 V rechargeable battery.

Abstract: An automatic irrigation system have an important role in today agriculture sector. Currently, automatic irrigation systems which can irrigate and supply plants with desired level and amount of water required for normal plant growth are not available. Furthermore, the classical method using on- off controller is inefficient due to results in loss of energy and productivity. Thus, an efficient automatic irrigation system with fuzzy logic controller is proposed to estimate the amount of water level using the irrigation model, soil type and type of plant. This paper presents a solution for irrigation system for plants using fuzzy logic controller using MATLAB Simulink. To indicate the effectiveness of the proposed method, on-off controller method is also applied for validation purpose.

Abstract: In the renewable energy power generation system, voltage source inverters (VSIs) are commonly used due to its stable operation, high efficiency and low cost. However, a dc-dc boost converter is necessary for VSI to operate has increased the system complexity. Thus, current source inverters (CSIs) has become an alternative of VSI due to its ability of voltage boosting and can provide a better output waveform. This paper presents a comparative evaluation of VSI and CSI focusing on topological circuits and basic operational parameters of these inverters. The performances of VSI and CSI are analyzed in MATLAB Simulink based on two operational characteristics which are modulation index, ma and switching frequency, fsw. The performance of VSI and CSI are dependent on the modulation index, increasing ma increase the inverter efficiency. In term of switching frequency, it does not affect much on the efficiency of inverters, but a normalized switching frequency should be an odd multiple of three. Furthermore, CSI presents its voltage boosting capability which can boost 6-27% within the ma of 0.05-1.0. Lastly, by using same SPWM modulation techniques, VSI and CSI have present duality relationship in term of switching signal and output wave shape.

Abstract: Three phase AC induction motor is the workhorse in industry where it counts for 85% of the type of motor used. They are mostly used as prime movers for fan, pump, and centrifuge where conventionally, operated at fixed speed. Variable speed drive has proven to give better efficiency compared to mechanical control such as using valve or damper in flow control applications. This may be attained through variable frequency drive (VFD) where stator frequency could be varied to adjust motor speed. For closed-loop control, fuzzy logic controller (FLC) can offer viable option for VFD over the more conventional PID controllers due to simplicity in design, bypassing the complex tuning process in PID while still giving good control performance. In this paper, SPWM signal is generated as inverter trigger signal using the algorithm derived from literature. A VFD system consist of three phase six pulse inverter triggered by SPWM signal generation algorithm and connected to three phase AC induction motor was designed and simulated using MATLAB/SIMULINK software. Speed test was performed in open loop design in order to obtain the ranges of operable frequency and speed control. Fuzzy logic controller was employed as closed loop control to improve speed control. Dynamic speed test was carried out to compare performance of open loop and fuzzy logic-controlled system. Simulation result shows superior transient response performance by 13% of fuzzy logic controllers.

Abstract: Low frequency energy harvesting using piezoelectric is one of promising method on harvesting energy from a free source. This method offered powering low load and remote device application. However, due to its nature which is inconsistency in providing the magnitude of input, specifically in low frequency harvesting, better solution to stable up and increase the converted output is explored widely. There are a few parameter that influences in the piezoelectric output generation. These parameter includes the type of piezoelectric, piezoelectric array configuration, AC-DC converter and etc. The types of the piezoelectric used in this project are the circular piezoelectric. When there is a force (motion) exerted on the piezoelectric disk, electrical charge was produced which initiated the energy conversion. In this research, the configuration of array connection for piezoelectric were investigated. The system is tested with different load configuration in a range of 10 kΩ to 1 MΩ. The design and development of the piezoelectric array variant were series (S), parallel(P), series parallel (SP) and parallel-series (PS). The observation emphasized on finding the best types of piezoelectric array configuration in producing optimum output of the harvested power. The simulation part consists of designing, simulating and analysing the result are done by using PSIM software. For validation of the simulation result, the implementation design of the hardware prototype that supplies pressure to piezoelectric have been done. In conclusion, a proper implementation of piezoelectric array configuration will produce optimum power output which can fulfil the minimum requirement of energy for powering low load device.

Abstract: This project proposes fault distance locator model for underground power cable using an Arduino uno. The use of underground cables arise a problem of identifying the fault location and the distance of cable fault as it is not open to view as in case of overhead cable. Thus, the underground cable fault distance locator is develop to detect the exact fault location and the distance of underground cable fault from based station in kilometers as the system will detect the faulted cable on underground and will send the information to the control room by using a relay. An underground cable system is a common practice followed in major urban area. The concepts of Ohm’s law are used in this project and are placed underground with short circuit type fault condition. If any fault occurs, the voltage drop will vary depending on the length of fault in cable since the current varies. Tracer method is used to detect faulted by walk through the cable lines. Fault point is traced by the audible signal or electromagnetic signal. These projects are equipped with a set of resistors, power supply, a set of switches, Arduino Uno and LCD. The prototype of an underground cable fault distance locator is designed with the performance of Tracer method.

Abstract: The electrical production is the primary performance of any solar photovoltaic (PV) system. The PV panel operating temperature is inversely proportional to the electrical production of the PV panel. The operating temperature of PV panel is influenced by solar radiation absorbed and the ambient temperature. In the present work, Computational Fluid Dynamics (CFD) method is used to investigate a three-dimensional (3-D) model of a PV panel. It is also essential to estimate the thermal behaviour of the PV panel under various environmental conditions. The primary purpose of this current work is to analyse temperature distribution from the PV panel under given operating conditions. The model geometry is built by using CATIA design software. ANSYS software was simulated the different intensity of solar radiation that applied to the PV panel in order to observe the temperature distribution on each layers of the PV panel. The ambient temperature of the simulation is fixed 35 °C according to the maximum ambient temperature captured in Malaysia. The simulation results show that an increase in solar radiation intensity along with the PV panel operating temperature increase.

This method could avoid human error in compaction timer hence reduce completed panel defect rate. Vacuum bagging/compaction process is a very important process to consolidate the laminates into a composite. Hence it is important for the precision of vacuum pressure and timing for the compaction process. The automatic device is designed to do the compaction process according to the timer automatically. The approach of designing this device is to use timer and solenoid valve to control the vacuum and a timer with a microcontroller. This device implementation will also reduce the steps of compaction process compared to the current way of doing so in Company A. In addition, it is believed to reduce the redundancy of work of the operators and increase multitasking of the operator and yield of composite panel produced by the company.

Abstract: The input voltage of battery charging system is always above the battery nominal voltage and it should be remained constant. But it depends on the type of input voltage sources. A battery charged directly by photovoltaic (PV) module as the input voltage source can cause the output voltage of PV module or the input voltage of battery charging system can fluctuate, because the output voltage of PV module depends on the solar irradiance. This problem can be solved by installing DC-DC boost converter between the PV module and battery. This paper presents a DC-DC boost converter based on PID controller for battery charging system. It is designed for the input voltage of 12V and output voltage of 14.7V system because it is applied to charge a 12 V, 7 Ah lead acid battery. Based on the simulation result of battery charging system shows that the output voltage of DC-DC boost converter can be remain around 14.7 V. It is due to the PID controller can damp the voltage oscillation and remain its steady state voltage. The time needed by the DC-DC boost converter to charge the battery in the fully charging condition is 1 hour: 3 minutes: 37seconds.

Abstract: Pulse width modulation technique is always applied in the design of inverter. The output voltage waveform of inverter is not relative pure sinusoidal, especially if it is applied linear pulse width modulation. A non-pure sinusoidal voltage waveform can affect the life time of inverter and also the alternating current (AC) loads. The inverter always also use a transformer that can increase the losses and reduce the efficiency. A technique of multiple pulse width modulation (MPWM) is suitable to be applied in the transformerless photovoltaic inverter (TPVI) system. It can generate pure sinusoidal voltage waveform and increase the performance of inverter. This paper presents a simulation of MPWM TPVI system using SIMULINK MATLAB. It consists of pulse driver circuit to drive four MOSFETs in the full bridge inverter circuit with the output voltage waveform still multiple pulse wave and it is converted to be pure sinusoidal voltage waveform by applying a LC filter circuit.

Gireesh Kumar A and C A Babu
Division of Electrical Engineering, Cochin University of Science and Technology, Kochi, Kerala, India
Abstract: This paper presents coordinated operation of power management strategies for a hybrid system. This hybrid system is modelled based on dynamic variation of load power and its effective distribution strategy. The proposed hybrid system consists of variable speed diesel generator (VSDG) and lithium-ion battery which is able to supply electric power for Power, Water and Communication (PWC) economically and efficiently in rural areas. The variation of power demand in PWC load is highlighted in load profile. The total PWC load is effectively shared by two VSDGs and one Lithium- Ion battery bank. The use of advanced VSDG helps hybrid system to reduce fuel consumption as its speed varies with load demand. The proposed segmentation of high frequency and low frequency components of load currents and their assignation to suitable source helps to reduce the transients during load variations. Also, one of the generators will be switched off when the total power demand goes below specified level and hence significant fuel savings can be achieved. The execution of proposed system is assessed through MATLAB/Simulink model and its validation by experimental test bench.
Keywords AC/DC converter, DC/DC converter, lithium-ion battery, loads sharing approach, variable- speed diesel generator.

Abstract: Reducing component in circuitry is desirable in many innovations. In multilevel inverter (MLI) perspective, the increasing of switching devices for a higher-level output will significantly increase power losses, thus affected the output harmonic distortion. In this paper, an extended and simplified three-phase reduce component count multilevel inverter (RCCMLI) structure adapted from S. S. Lee, Cascaded Compact-Module Multilevel Inverter (CCM-MLI) is demonstrated and analysed. Symmetrical reduce component structure with H-bridge inverter is considered in this work. For simplification purpose, the current path conduction for reverse current is not demonstrated in this paper. A simulation-based result is presented to observe the performance of RCCMLI with regards to its output voltage harmonic content. Related predetermined parameter values are included in this report. Particularly, this paper verified the aforementioned RCCMLI, but in higher level and three- phase application, which will further improve the pseudo-sinusoidal inverter output as it eliminates the triplens harmonic component compare to single-phase environment. As for the lower order odd harmonics elimination, computational algorithm namely Particle Swarm Optimization (PSO) has been implemented in the RCCMLI control strategy. In comparison to the traditional Cascaded H bridge (CHB), this work finds that employing the switching angle optimization in the proposed RCCMLI produce comparable improvement in minimizing the output voltage harmonic and able to bring the output quality closer to comply with IEEE 519 distortion limit with fewer components and compact size inverter.

Abstract: This paper reports analytical modelling of the squeeze film damping effect of a standard Polysilicon Multi-Users MEMS Process (PolyMUMPs) resonators. PolyMUMPs resonator has been designed for the purpose of gas detection. Generally, damping is present in all vibrating systems in the real world with an exception of systems vibrating in a vacuum environment. The air damping is considered the major source of energy dissipation and has a main influence on these vibration systems. To reduce the effect of the squeeze film damping, the movable top plate of the PolyMUMPs resonator has been investigated by changing the size of the etched holes perforated to improve the resonance frequency and quality factor of the PolyMUMPs resonator. Electrothermal actuation method will be used to drive the resonatorin the dynamic mode and the output voltage will be measured using an MS3110 universal capacitive readout circuit. The results show that by increasing the size of the etched holes from 6 µm to 10 µm, the squeeze film damping is decreased from 47.303 μN.m to 24.007 μN.m, respectively. This will affect the resonance frequency to increase from 3904.022 Hz to 4483.783 Hz, as well as and the quality factor from 0.999 to 1.912, respectively.
Keywords MEMS devices, PolyMUMPs resonator, quality factor, resonant frequency and squeeze film damping.

Abstract: Our world is experiencing major technological changes and this time it is centered not on internet but Internet of Things. Actually Internet of Things is sincere effort to connect all unconnected especially smart objects By doing so human wants to challenge their own way of thinking that shouldn’t all objects be connected to one central network and among themselves so that as human we can control them all. So paradigm is let us provide capability of objects to exhibit the ability to communicate to each other as well to one central system thus to human beings. This effort would certainly bring new improvements and efficiency in our lives. It is this very premise behind Internet of Things (IoT) that would see new transformation and revolution in industrial world from manufacturing, logistics and supply chain in current industrial world of 4.0 and future newer versions.
Over last few decades Information Technology (IT) has been witnessing strong and active cyberattacks and creating protection threats to the cyber security networks. Information Technology industry has learnt lot from these threats and have also documented them to find right and appropriate solutions. In contrast Operational Technology environment surrounding Information Technology were kept in abeyance in many organizations. Thus one hardly finds history and documentation of cyberattacks systems built around operational technology. This also makes fewer learning opportunities and record of catalogued incidents and their corresponding risk mitigation strategy not rich in record. It is worth knowing that the world of operational technology addresses wider scope and higher depth in comparison to Information technology. In Operational Technology the word security and safety are synonymous with each other. It is reality that many of the industrial security standard also incorporate equipment, instruments and safety recommendation by experts thus lay the foundation of IoT security.
This paper provides a historical perspective of Operational Technology security, the security system measure, how over a period of last few decades the subject matter has evolved, what are few of the real challenges industry is facing. The final phase of paper focuses on some of the real practical measures and steps have been to taken to in creating more safe and secure industrial environment including best practices in creating synergy between Information Technology networks security and old aged legacy industrial environments.

Abstract: A high penetration of renewable energy in power systems gives rise to the inverter based distributed generators (DG) in the current microgrid system. With the ability of microgrid to operate in both islanded and grid connected mode, a robust and reliable coordination and synchronization between the DGs and the utility grid is crucial to provide a seamless transition between operation modes. Droop based technique is the most popular method in microgrid system, however, voltage or current transient are present during mode transition. A power offset synchronization technique is proposed to provide a seamless transition between modes of operation. The results show that the mode transition is smooth and seamless without any voltage or current transients.

Abstract: In this work, the advantage of using Maximum Power Point Tracking (MPPT) algorithm in solar Photovoltaic (PV) system was investigated. By simulation, the performance and efficiency of the system with and without the tracking algorithm was analyzed. By using MATLAB’s Sim Power System block set, a model compromised of KC130TM solar panel powering a Zeta converter controlled by MPPT algorithm driving a lead acid battery as a load was designed. The main objective was to track the Maximum Power Point (MPP) of the solar PV module by modulating the zeta converter’s duty cycle, thereby, optimizing the power output of the panel. The Perturb and Observe (P&O) algorithm preformed with higher overall efficiency compared with the system without MPPT. Additionally, the tracking algorithm was able to track the MPP quickly. The analysis of the algorithm led to a greater understanding of where the inefficiencies of this type of system are located, allowing improvement in future work on this field.

Abstract: The arcus cornea is an eye problem that is often encountered among older people, but the situation is risky to teenagers and young people, in which it gave a sign the presence of lipid abnormalities in their blood and the risk of disease problems such as diabetes and heart disease. This paper presents the classification of the arcus cornea, using the extraction of texture features of the gray level co-occurrence matrix, along with several models of the classifiers, namely as scale conjugate gradient, Bayesian regulation, and Levenberg-Marquardt. Percentage fractions for training, testing and validation for classifier are 70%, 15%, and 15% respectively. The comparison of the classifiers used by the past researchers for classification the eye abnormalities, also were analyzed and studied in this work. In this experiment, a total of 125 image eyes were used, consisting of two classes of the eye image, which is normal and abnormal. The best result demonstrated in this proposed framework using Bayesian regulation classifier is, a sensitivity of 96%, and a specificity of 100%. However, this classifier did not achieve perfectly classification or an accuracy of 100%. Nevertheless, it is able and evident that the system is effective by the output of 98.4% accuracy.

Abstract: The Electric Field and Voltage Distribution (EFVD) are important parameters for assessing high voltage bushing transformer performance. However, conducting laboratories experiment are dangerous, difficult and expensive due to several aspects. Therefore, Finite Element Method (FEM) software is the best option used as a tool for the assessment of bushing transformer's performance in terms of EFVD. But, before an assessment of analysis could be carried out, an accurate model of bushing transformer must first to be designed. In this research, Computer Aided Design (CAD) software has been employed to design the 145kV bushing transformer based an actual dimension. Upon completion, the design has been exported to FEM software for further analysis. In FEM software, measurement and analysis of electric field and voltage distribution (EFVD) have been carried out. The measurements are performed at various locations of bushing transformer such as of the porcelain surface (both air and oil side), along with aluminium foils, and at oil-impregnated paper (OIP). The results obtained have been compared with other researchers and it is found is very satisfactory. The designed bushing transformers are ready to be used to study the performance of bushing transformers in a variety of conditions.

Abstract: Total Harmonic Distortion (THD) is one of the problems in the multilevel inverter. This paper discussed a brief review of THD in different cascaded H-bridge multilevel inverter topologies of five levels and seven levels at the output waveforms. The five levels inverter contains eight switches while seven levels inverter used twelve switches. Each single H-bridge inverter circuit is fed by equally in dependent DC source for both inverters. The inverter uses MOSFET as the switching point and acts as the controller for a fundamental switching operation. The switching value has been set at the gating block to control the operation of the MOSFET switching. To validate the performance of proposed topology, various waveforms and simulation results are presented.

Abstract: In recent years, the advance usages of non-linear loads have led to the serious power quality problem in the distribution system. Non-linear load will inject the current harmonics and cause power quality problem at Point of Common Coupling (PCC). This problem can be improved by using power filter. Power filter can be divided into passive power filter and active power filter. Passive filter is an appropriate solution to solve power quality problem in term of harmonic mitigation due to a simple circuit, low cost and less energy requirement. However, active power filter (APF) is more suitable due to better performance to solve power quality problem for current harmonics issue. This paper focuses in designing the application of a multi-functional grid-connected solar PV system integrated with DSTATCOM by using Instantaneous Reactive Power (PQ) theory controller to mitigate the current harmonics injected by non-linear load at the distribution system. MATLAB/SIMULINK software is used to simulate the performance of the multi-functional GCPV based SAPF according to IEEE Standard 519:2014 which THD of the line current at the Pont of Common Coupling (PCC) should be less than 8%..

For the validation, a horizontal band saw was used with 3 axes of displacement implementing 2 cameras with stereoscopic vision and finding an estimation of depth in the cut. With the dimensional deviations (x,y,z) of the cut, the shape and dimension of the cuts in the pipe, are defined to be manipulated and classified in correct and in-correct cuts by means of a separator coupling. For this purpose, algorithms were developed on two computer platforms: LabVIEW, which obtains the images, controls the automatic separator and the material feeder; Matlab, which processes dimensional deviations by recognizing patterns with the "Principal component analysis" (PCA) technique, in turn compares with an ideal pattern and optimizes the cutting parameters: Cut speed, cutting index ,through a derivative Integral Proportional PID algorithm with the interaction of machine learning (ML) based on SVM theory. Autonomously corrects errors without human supervision, obtains the lengths and depths with the optimum cut-offs and result of adaptive supervision, increases production, product quality and reduces operating costs for each cutting cycle by com-plying with Overall Equipment Effectiveness parameters (OEE) and integrating into intelligent manufacturing systems.

Abstract: Every electricity networks have some critical components and power transformers are one of it. Gathering the data on the severity of voltage sag occurred in a network is significant in a power quality monitoring program. During transformer energisation, there are three common problems occur which are number of inrush, sympathetic inrush current and voltage sag. With the increase of distributed generations with inherent high intermittency resulting in more switching events, the transformers are increasingly vulnerable to electrical transients. This project is to study and analyse the inrush current, sympathetic inrush current and voltage sags and its severity in transformer energisation. The magnitude and duration are two characteristics of voltage sags that need to study. To investigate this matter, the networks are designedusing the PSCAD software. Same rated three phase 100 MVA, 230/33 kV transformers are used to analyse inrush current, sympathetic inrush current and voltage sag. Analysis for this project is carried out for assessing the voltage sags in several cases; (a) by different number connection of transformer, both when it is simultaneously energised or energised at different times, (b) different configuration of transformer (step-up and step-down) and(c) by varying the resistance source.

Abstract: Fault detection plays a key role in high cost and safe-critical systems to avoid the occurrence of an abnormal event. This work presents a model-based fault detection in the water management system of proton-exchange membrane (PEM) fuel cell stack using Kalman filter (KF). The KF is a model-based FD method relies on analytical redundancy to predict the related fault disturbed by some noise. Then, it corrected the faults with its mathematical model to minimize the error covariance between the normal and faulty scenarios by a repetitive process. Two faulty scenarios; flooding and drying which happen at anode and cathode side of PEM fuel cell are investigated. The proposed FD method using KF has successfully detected flooding and drying faults in PEMFC.

Abstract: Abnormal rises in temperature of an electrical equipment could be a sign of electric fault. By measuring the temperature of the equipment, it is possible to detect the early sign of electrical failure. Therefore, preventive maintenance based on thermal inspection is important to ensure the safety operation of the electrical system. Thermal inspection is normally done by using a handheld thermal camera. However, professional thermal camera is expensive and not suitable to be installed at a fixed location for continuous temperature monitoring. In this paper, a low-cost embedded system is proposed for measuring the temperature of electrical equipment based on thermal imaging. The system can be permanently installed to continuously monitor the thermal condition of an electrical installation. The proposed system consists of a Raspberry Pi 3 controller board connected to a MLX90640 3224 pixels thermal sensor and a Pi NoIR camera. The temperatures measured by the thermal array sensor are converted into a heat map to form a thermal image. The thermal image is then overlaid on the visual image and displayed on the LCD screen. The system can be programmed to generate warning signal when the measured temperature is above a certain threshold value. Experiments carried out on the developed system showed that it is able to locate the hotspot regions of an electrical installation.

Abstract: Steganography is the process of hiding secret information in other multimedia files, like image, audio, video such that any unauthorized person does not have any clue of the hidden secret data. Due to the computational advancements and increasing risk in secure communication, steganography has become one of the most researched domains in information security. In this paper, a novel method of steganography is approached where the cover image is scrambled using graph theory; then data is embedded in the LH, HL and HH planes using LSB embedding of the cover image after applying Haar forward transform to get the embedded image. The secret data hidden in the cover image is first converted to a QR-like (Quick Response) image and then to be embedded in the cover media. The stego image is obtained after reverse Haar transform and descrambling of the embedded image. The proposed method when applied to a set of grayscale images, the stego images obtained not only show a greater embedding capacity but also shows high Peak Signal to Noise Ratio (PSNR) and a low Mean Square Error (MSE) and very appreciable Normalized Cross-Correlation (NCC) along with a good Structural Similarity Index Matrix (SSIM) when compared to the cover images.

Abstract: The nationwide usage of cross-linked polyethylene (XLPE) for medium to high voltage distribution networks are practically common due to its excellent electrical, thermal and mechanical properties and widely installed through existing network of cable line in Malaysia. However, cable exposures to harsh climates coupled with inadvertent damage throughout installation or transportation are influencing the presence of voids inside the insulation leading to the initiation of partial discharges (PD) in the cable line. Therefore, this study is important to investigate the activities of PD due to the manifestation of voids in XLPE cable and how it affects the physical, electrical and mechanical characteristics of the cable. Analysis has been performed using Finite Element Analysis (FEA) tool to simulate the PD activities in a 2D model of a three (3) core-XLPE insulated armoured sheathed cable (500 mm2, 11 kV)with several placements of voids. The varied placement and radius of voids is very crucial in order to achieve comprehensive analysis. From the obtained result, it has been established that closest the void to the core yielded higher electric field potential. Additionally, it is verified from the simulation that the larger the size of void, the higher the electric field potential consequently increasing the current density inside the void. This simulation and analysis is quite important to provide better insight pertaining to the behaviour of PDin correspond to the presence of voids which will accelerate ageing failure in insulation framework of the XLPE cable.

Abstract: In this paper, an empirical relationship between the surface leakage current (LC) with humidity and applied voltage stress is proposed by using Dimensional Analysis (DA) technique. DA introduces a systematic approach based on Buckingham Theorem to presents a complex relationship between the physical quantities into a dimensionless set of products. For validation purpose, the results obtained from the proposed mathematical model are compared to the practical data from the previous researchers. The validation shows that the analytical results are within the range of experimental results. By further analyzing the quantitative error analysis; mean absolute error (MAE) and root mean square error (RMSE), the proposed model is found able to be used as a predictive model to estimate the performance of surface LC at different relative humidity and applied voltage stress.

Abstract: This work proposes the dual axis solar tracker with mirror reflection for optimum output of solar panel by using arduino unoR3 as the control unit. The objectives of this work are to track and optimize the maximum output power of the solar panel by designing and developing a dual axis solar tracker with mirror reflection. The system includes a 10 watt solar panel, an arduino unoR3 and a customized mechanical body to carry the solar panel. This system will track and detect the angle of the sun to locate the surface of solar panel at the position and the angle where it can get maximum amount of energy. The sensors will detect the position of the sun and servo motors act as free moving neck to make it easier to move freely depending on the angle detected. The Light Depending Resistor (LDR) will be used in tracking system. These LDR will detect the existence of sunlight and therefore the mechanical hardware will move horizontal and vertical axis depending on the value of LDR detected to follow the angular degree of sun in order to get maximum and best result of absorbing energy. The final result obtained from dual axis solar tracker showed that the output power has been maximized compared to stationary panel. Based on the experimental result, it show that the designed system successful improve the performance of the solar panel.

Department of Embedded Technology, School of Electronics Engineering, Vellore Institute of Technology, Vellore, Tamilnadu, India
Abstract: In genome assembly, sequence analysis, error correction in sequence reads, k-mer (substrings with length k in a DNA sequence) counting plays a momentous role. Even though counting the number of occurrences of k-mers has a simple principle, for huge amounts of data, k-mer counting has become a challenging task, since a simple strand of a sample of DNA could contain multibillion sequences which could surely inundate the capacity of storage in regular computing machines. In the prevailing data sets, a massive portion might be used in storing those k-mersthat have sequencing errors and that are commonly noticed only once in the data. Such k-mersare enigmatic with no information for most kinds of algorithms. So, error correction plays a compelling role in eradicating such uninformative k-mer.In this paper, we bring forward a new method that helps determine k-mer that appear at least twice in a data set of a sequence of a DNA. We achieve this by using Bloom-1 filter data structure that is used to store all the k-mersthat have been inherently observed in the memorywith massively minimized requirements in storage space and by using bloom-1 filter, we are able to reduce time consumption.

Abstract: This paper proposes a new circuit topology of single phase AC to DC Series-Parallel Current Injection Resonant Converter (SPCIRC) with wireless power transmission function. Thus, characteristics are accomplished such as shaping the current waveforms of the sinusoidal line with improved power factor resulting in small total harmonic distortion (THD). This is implemented by employing the resonant conversion technique, involving two active soft switches that generate high frequency currents. The circuit operation is explained and the analysis of the converter is presented. The full detailed circuit simulation is then carried out to ascertain the workability of the converter and its ability to operate with wireless power transmission. As a result, a low input current THD of 3.52% was obtained with 130V output DC voltage when supplied by 240V AC input voltage. The efficiency of the proposed SPCIRC is calculated as 87.5%. The current injection topology's main operation is described in detail.

Abstract: Low degradability level and abundance in solid waste, as well as an increasing the required number of landfills, are the concerned arise from plastics waste management. In this respect, the need to recycle plastic is currently important. Therefore, this paper aims to investigate the potential recycling three types of food packaging plastic wastes (denoted as BPPWL, JPPWL, and IPPWL) to be a liner material which could be used in civil engineering. The plastic waste liner was prepared by heating several layers of the similar plastic waste under the applied pressure of 476 Pa and temperature of 150ºC. Tensile analysis depicted plastic waste liner which fabricated from a single layer of plastic unable to meet the requirement of a commercialized liner, known as geomembrane. On the other hand, the tensile strength greatly increased when the plastic waste liners were fabricated from several layers of plastic (multilayer) in which the yield strength achieved to more than 6 kN/m. Yet, the multilayer liners are more brittle or low deformability than the single-layer liner. Based on the tensile analysis, it can be deduced that the multilayer liner of BPPWL, JPPWL and IPPWL are possible to replace geomembrane liner specifically when it is being used in the construction of railway tunnels and road but not the liner in the landfill application as higher tensile strength is required.

The sequential process of the work is defined in three different phases where in the first phase human face is detected from the camera and in the second phase, the captured input is analyzed based on the features and database used with support of keras convolutional neural network model. In the last phase human face is authenticated to classify the emotions of human as happy, neutral, angry, sad, disgust and surprise. The proposed work presented is simplified in three objectives as face detection, recognition and emotion classification. In support of this work Open CV library, dataset and python programming is used for computer vision techniques involved. In order to prove real time efficacy, an experiment was conducted for multiple students to identify their inner emotions and find physiological changes for each face. The results of the experiments demonstrates the perfections in face analysis system. Finally, the performance of automatic face detection and recognition is measured with Accuracy.

Abstract: Despite the existing advances on research and education in cybersecurity and its applications, the field is still under discovery and new technologies are evolving. In recent years, Bitcoin as a cryptocurrency cyber application that records all financial transactions present on a blockchain where users can reach a secure and robust consensus on transactions emerges as the most popular peer-to-peer electronic payment system. Cryptocurrencies mostly rely on blockchain, as a secure decentralised append-only ledger to exchange digital currencies, and thereby attracting a billion- dollar economy. Bitcoin allows the inputs and outputs of cryptocurrencies to link to Bitcoin public address systems vulnerable to possible and traceability of users’ identity. This obviously attracts privacy issues such as user’s information and identity leakage. Several existing techniques are found not satisfactory to fulfil practical and compatible anonymity requirements for users to transact financial transactions with cryptocurrencies securely. In this paper, we focus on unlinkability and untraceability of users in bitcoin cryptocurrency transactions and present a secure privacy-preserving scheme based on bilinear pairing and other cryptographic primitives to curb users’ privacy breaches. We theoretically analyse and evaluate our proposed scheme which is proven secure and robust to implement for preserving users’ privacy in bitcoin transactions.

Abstract: A primary concern of multilevel inverter is its capability to produce desired alternating voltage close to sinusoidal at the output, using multiple sources of DC voltage input. Mostly a multilevel inverter is used to generate the AC voltage from DC voltage. The aim of this paper is to investigate the output of 9 level multilevel inverter by modifying the conventional 5 levels H-bridge cascade multilevel inverter. The proposed design intending to reduce the number of switches from 16 switches to 10 switches. Implementation of different switching pattern methods; equal phase (EP), half equal phase (HEP), half height (HH) and feed forward (FF) and the related expression are presented in this paper. In the result section shows a different percentage of total harmonic distortion achieved. Out of all 4 methods, HH method suppressed distortion wave the most and resulted in the lowest THD in the proposed inverter. This paper shows that by reducing the number of switches in multilevel inverter structure maintains the same quality output as the conventional H-bridge topology. Furthermore, the manipulation of the switches firing angle contribute in decreasing the system THD.

Abstract: This paper presents the design of speed sensorless vector control of PMSM by using MRAS method. The adaptation scheme used in this project is based on the Takagi Sugeno FIS method. It is implemented to replace the conventional method which is proportional-integral (PI) controller. This new technique is based on Takagi Sugeno Fuzzy Inference System (TS-FIS). This new method can overcome the problem of tuning parameters in the traditional method when there is a change in the motor condition such as variation of load and speed. The efficiency and accuracy of the proposed designed in detecting rotor position angle is validated in Matlab/Simulink and obtained results are compared with conventional method. The analysis is carried out by comparing the both methods, MRAS-TS and MRAS-PI in different cases of motor conditions. It shows that the proposed method can track the motor speed and rotor position angle accurately.

Abstract: Longer service period of insulation system in high voltage has cause major problem to the high voltage equipment which typically due to ageing and deterioration. This will lead to the occurrence of Partial Discharge (PD) and immediate failure of the power system. Nowadays, PD measurement is applied to detect the occurrences of the PD. However, PD measurement has faced problem of unwanted noise in the measured PD signal. Therefore, Discrete Wavelet Transform (DWT) de-noising technique is widely used due to viable and superior characteristic of DWT in rejecting different kinds of noise from measured PD signal. Thus, the performance analysis of DWTde-noising technique based on various decomposition level and different type of mother wavelet, such as Haar, Daubechies, Coiflets, Symlets and Biorthogonal via LabVIEW software were carried out. The performance of de-noising technique is analysed based on Mean Square Error (MSE) of the PD signal in order to select the optimum mother wavelet in the de-noising process. Minimum MSE will promising the optimum mother wavelet. Based on the result, bior5.5 wavelet had the lowest MSE value, thus selected as the most optimum for PD de-noising application.

Abstract: Abstract. In this research work, a n-type silicon tunneling field effect transistor (TFET) has been designed and investigation has been carried out on its performances by altering different device parameters such as gate insulator dielectric constant, channel thickness, gate geometry, and channel length. The performances have been evaluated based on subthreshold swing, threshold voltage and Ion/Ioff ratio of the devices. The goal is to find a device which would simultaneously have a low subthreshold swing (SS), low threshold voltage, and a high Ion/Ioff ratio. It has been observed that having a double gate, short channel length, high-k dielectric, and low channel thickness leads us towards a compact design and the device exhibits very promising values of the aforementioned performance criteria. The most attractive proposition about a TFET is its ability to have a subthreshold swing lower than 60 mV/dec which is the theoretical limit of a MOSFET. In this study, an optimized device is obtained which has a subthreshold swing (point) of around 26 mV/dec and an Ion/Ioff ratio in the order of 1013. In addition, an inverter has been designed using a n-type TFET and a resistor to show the potential of TFETs to be used in logic circuits.

Abstract: This paper present the design and simulation of a 30 kW DC to AC inverter. The inverter is designed based on the Zeverlution Pro 33K three-phase DC to AC inverter. Currently, there are 6 units of the inverters installed at 180 kW solar power plant located at MukimUtanAji, Perlis. So in this paper, the results from the computer simulation will be compared to the site measurement conducted from this power plant. In this design, pulse with modulation (PWM) is used as the switching technique. Even though PWM offers the ease of LC filter design and low Total Harmonic Distortion (THD), the voltage amplitude of the sine wave output fails to achieve the required national grid parameters, i.e 240 Vrms. To overcome this problem, a three-phase transformer has to be incorporated in the design to obtain the desired outputs. Results from computer simulation using SIMULINK show that the targeted AC parameters for all phases were achieved after comparing with the site measurement

Abstract: The rapid growth and remarkable evolution of information and communication technologies have brought new challenges in healthcare information systems. The possibility of malicious adversary to intercept or tamper private medical data has increased particularly during transmission and storing process through public network. Therefore, digital watermarking is used as an alternative solution for a number of issues associated with medical data management. This paper presents a watermarking technique for medical images using Knight’s Tour approach. Two types of watermarks namely caption watermark and signature watermark were utilized. The Knight’s Tour algorithm is applied onto the host image to formulate embedding sequence. The extraction process is similar to the above embedding except it is accomplished in are verse order. Experimental results show that the proposed technique is resilient from intentional attacks.

Abstract: The process of liberalization of the electricity sectors around the world has given way to the introduction of competition in a number of supply chain activities. The Colombian electricity market is no stranger to this scenario. In this country, since the Constitution of 1991, competition wherever possible and free entry to any agent interested in providing public services was accepted as a key principle for achieving efficiency in public services. The State began to play the role of regulator, while a restructuring of the market was presented under Laws 142 and 143 of 1994, whose purpose was to increase the efficiency of the system and link private capital to it, and the establishment of the Energy Exchange in 1995 [1]. These laws defined the regulatory framework applicable to generation businesses, as well as transmission, distribution and marketing. The work described in this article explores the possibility of employing a model based on fuzzy logic and machine learning for marketing agents of the Colombian electricity market.

Abstract: When talking about electric power, the first thing to think about is whether enough electrical energy is generated to use without paying attention to it, similar to thinking that water will never runs out, but when faced with extreme droughts, people think that water can be depleted and they must save. In this sense, electrical energy must be saved and used completely and that is why the term energy efficiency is born. This new trend seeks to save electric power to avoid electricity supply shortages, as when countries face phenomena such as El Niño that generate droughts in some areas and rains in others. So, saving energy is a trend because it is importantto be prepared for these phenomena, and guaranteeing a sustainable country. This document shows the importance of energy savings, as well as the need to design intelligent models that help to support the reduction of the problem of excessive consumption of electricity..

Abstract: Since a few years back, the Malaysian government has been searching for an opportunity to realize the first wind farm in Malaysia in a path to achieve 20% penetration of renewable energy by 2025. Even though the average wind flows in Malaysia is low, but with the rapid advancement of micro-wind turbine technology promises a potential enhancement of wind harvesting in Malaysia in the near future. High wind penetration to the grid will cause severe technical problems because of its fluctuating and intermittent nature. In view of that, this paper proposes a dispatch strategy for a wind farm comprising micro-wind turbine generators supported by a battery to minimize the fluctuation where for every monthly interval, a different value of reference power is followed. In parallel, the lower and upper constraints of battery state-of-charge are to be satisfied. The proposed strategy is validated using the real wind data measured at Mersing, Malaysia. The results reveal that the proposed strategy successfully reduces the fluctuation and achieves the reference power for most of the intervals while ensuring the battery operates within a safe operating region. Using the simulation results, the payback period is estimated, which exposes that this project as an example, requires about 20 years of period to reimburse the capital expenditure.

Abstract: This paper focused on the classification of student national-level status such as national and international. A primary survey was conducted in the academic year 2017-2018 to analysis the circumstances of trending ICT and Mobile Technology (MT) in Indian and Hungarian higher education. The main objective was to identify the student's answers provided in the survey based on their national-level status. For the classification tasks, we used Logistic regression (LR), Support Vector Machine, Multilayer perceptron (MLP) and Random Forest (RF)on both balanced and unbalanced datasets with K-fold Cross-Validation (KCV), Leave One Out (LOO), and Hold Out (HO) methods. Also, Xtreme Gradient Boosting (XGB) classifier was also implemented to enhance the classification accuracy of existing classifiers. The findings of the study showed that the XGB classifier outperformed others with the highest accuracy of 95% with 18 significant features. Also, class balancing improved significantly the accuracy of classification. Further, the authors recommended this predictive model to be implemented as a real-time function utility on the website of the university.

Abstract: The perturb and observe (P&O) algorithm is an easy and effective method used for tracking maximum power point. However, this technique suffers from deviation when irradiation changes suddenly. Moreover, the impact of this deviation is high when the insolation variation is rapid. This error is due to the incorrect decision taken by the conventional P&O method throughout the first step- change in the duty cycle during the increase in irradiation. The proposed P&O is a modified conventional P&O that focuses on using additional dI parameter with variable step size ∆Dn. In this manner, the conventional P&O algorithm is allowed to identify the source of deviation caused by rapid irradiance changes. The efficiency of the proposed P&O is assessed using simulation in MATLAB/Simulink. Results show that the proposed P&O effectively tracks maximum power and prevents deviations in rapidly changing climate conditions within a short time, which is lesser than the conventional P&O method. In addition, the proposed P&O has a rapid dynamic response. A DC–DC boost converter is utilized in this work to validate the proposed P&O algorithm.
