Transducer excitation is included as well as parameter controlled signal processing, indication of output levels, error supervision and operation of optional external equipment. The instrument supports several types of communication interfaces. INSTRUMENT INSULATION AND GROUNDING The cable connector for mains power supply should include protective grounding for safety. The cable for 24VDC power supply (screw terminal connector) should include a ground connected to terminal GND. The input groups of the instrument are insulated from each other by functional insulation. The mains connection of AC-powered instruments has reinforced insulation according to IEC 61010. Terminals intended for connection of cable shields are connected to the protective ground of the mains or GND terminal of 24VDC input but must not be considered as protective grounding. Shield connection of load cell input is not connected to mains protective ground or 24VDC GND terminal. Change description Document revision 0: New manual for program version 1.4.X Compared to Program version 1.3.X the following is added: - Fieldbus option PROFINET. - German and French languages. Document revision 1: G5-RMD added (program version 3.4.X). This manual applies from program versions 1.4.1 and 3.4.1. Document revision 2: The following parameters have new default values: Serial Com. Mode is default Modbus RTU Slave. Baudrate is default 115200. Modbus TCP Slave is default On. This change applies from program versions 1.4.2 and 3.4.2. G5 Weighing Instrument 1. Introduction General The G5 Instruments are high performance single-channel weight indicators (PM model, panel mounted) or weight transmitters (RM and RMD models, DIN rail mounted) intended for industrial systems. The basic function is to convert the signals from strain gauge transducers to useful weight information. Transducer excitation is included as well as parameter controlled signal processing, indication of output levels, error supervision and operation of optional external equipment. As long as the error supervision detects no error, a signal called ‘In process’ is then present but if an error is detected, ‘In process’ will be off and a specific error message will be displayed. ‘In process’ can be set to control any digital output. Note that there are weighing channel specific and instrument specific error detection. All functions in the G5 Instrument are controlled by set-up parameters. Setting of parameter values can be done from the PM and RMD´s front panels and also from the web browser. Set-up of a RM model must be done with a web browser in a PC that is connected to the instrument via Ethernet. Maintenance functions can be accessed locally (PM and RMD) or remotely (PM, RMD and RM). It is possible to load new software into the instrument using a SD-Card. The instrument has 4 level supervising functions and 4 set-point functions. Power supply The G5-PM (panel mount indicator) is available as 24 VDC model or 110/230 VAC model. The G5-RM and G5-RMD (rail mount versions) are available as 24 VDC model. All input and output signals are galvanically isolated from the power supply. Strain gauge input Both excitation voltage and the output signal from the transducer are measured at the transducer to avoid influence from voltage drop in the connection cable. Excitation to the transducer, from the G5 Instrument is provided over separate wires. A shielded 6-wire cable must be used to connect a distant transducer to the instrument. The analog signals from the transducer are converted to digital form and filtered to give an internal transducer signal with high resolution. The transducer excitation and signal values are combined to form an internal transducer signal, representing the load on the transducer. Influenced by calibration data, this signal is converted to a digital measurement value, the weight value, which can be presented at the local display window and at external equipment. 1-1 Technical Manual Communication The instrument utilizes the serial interface, Ethernet and a fieldbus interface for communication with control system or computer. The serial interface consists of a RS- 485/RS-422 connection that can be used with 2- or 4-wire connection. Weight values, level status, error status etc. can be collected and commands given through the communication interfaces. G5 Instruments can be controlled from a master computer or PLC using the serial interface, Ethernet interface, field bus interface or digital I/O. Modbus RTU protocol is used for the serial interfaces and Modbus TCP for the Ethernet connection. Optional fieldbus interface for Profibus, DeviceNet, ControlNet, EtherNet/IP or PROFINET can be used. The serial port can also be used to connect a

  • Machine Transliteration for English to Amharic Proper Nouns
    International Journal of Computer Science Trends and Technology (IJCST) – Volume 5 Issue 4, Jul – Aug 2017 RESEARCH ARTICLE OPEN ACCESS Machine Transliteration for English to Amharic Proper Nouns Melaku Kore [1], Vishal Goyal [2] Research Scholar [1], Associate Professor [2] Department of Computer Science Punjabi University, Patiala India ABSRACT In the advent of modern technology machine transliteration has gained a center of attention for research. Both machine translation and transliteration are important for e-governance and web based online multilingual applications. Machine translation is the process of translating the source language to target language which results in wrong translation for proper nouns, technical terms and cultural specific words. Therefore, transliteration is the way of keeping correct translation for such type of case. Machine transliteration is the process of transcribing the source language script to the target language script by preserving the source language pronunciation. In this work, the main focus is the transliteration of English to Amharic proper nous. The proposed work follows the rule based approach of machine transliteration technique. Different challenges arise during the development of this work, such as the repetitive nature of Amharic scripts, one to multi mapping, multi to one mapping, character gap and the creation of wrong word due to different rules. Solutions for such problems and appropriate algorithm have been developed. The result is evaluated using precision and it shows that 90.08% of the input proper nouns are correctly transliterated. Keywords: - Machine transliteration, Rule based approach, Grapheme Based Model, Phoneme Based Model, Tokenization. I. INTRODUCTION II. DETAIL STUDY OF THE PROBLEM AND LITERATURE REVIEW Ethiopia is [10] a multilingual country with over 85 A.

  • Symbols for Nothing
    Symbols for nothing: Different symbolic roles of zero and their gradual emergence in Mesopotamia Dirk Schlimm and Katherine Skosnik Department of Philosophy, McGill University, Montreal September 30, 2010 Abstract Zero plays a number of different roles in our decimal place-value system. To allow for a nuanced discussion of the importance of zero, these roles should be distinguished carefully. We present such a differentiation of symbolic roles of zero and illustrate them by looking at the use of symbols for zero in ancient Mesopotamia. Old and Late Babylonian mathematicians used a place-value system (like ours, but with base sixty instead of ten), but did not use zeros in the way we do now. This shows that our current uses of zero are not a necessary consequence of the adoption of a place-value system and that the lack of a zero does not necessarily render a place-value system unusable.1 1 We would like to thank Rachel Rudolph for her comments on an earlier draft of this paper. Work on this paper was funded in part by Social Sciences and Humanities Research Council of Canada (SSHRC). 11 1. Introduction In recent years philosophy of mathematics has begun to pay more attention to mathematical practice, both contemporary and historical. This is evidenced by the recently edited collections by Ferreirós and Gray (2006), Mancosu (2008), and van Kerkhove (2009). With this development, the use of notation has also come to receive more attention. This is not to say that these philosophers adhere to any particular formalist philosophy of mathematics, but rather that they recognize the fact that notation is one of the main tools of working mathematicians.

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Today, the division of zero by zero (0/0) is a concept in philosophy, mathematics and physics without a definite solution. On this view, we are left with an inadequate and unsatisfactory situa- tion that we are not allowed to divide zero by zero while the need to divide zero by zero (i.e. divide a tensor component which is equal to zero by another tensor component which is equal to zero) is great. A solution of the philosophically, logically, mathematically and physically far reaching problem of the division of zero by zero (0/0) is still not in sight. The aim of this contribution is to solve the problem of the division of zero by zero (0/0) while relying on Einstein’s theory of special relativity. In last consequence, Einstein’s theory of special relativity demands the division of zero by zero. Due to Einstein’s theory of special relativity, it is (0/0) = 1. As we will see, either we must accept the division of zero by zero as possible and defined, or we must abandon Einstein’s theory of special relativity as refuted.
