Foreigners need to converse using Thai. The phonology of this language causes mapping from one system of writing into another and data control to be complicated. The calibrating of sounds from one language into a workable writing system called transcription as opposed of transliteration, which maps the letters of the source script to letters pronounced similarly in the target script. This paper proposes a new algorithm, which allows users to use Roman characters to transliterate into some specific Thai words. As a result of this study, Thai Romanized Input Method Editor is a transliteration system when implemented has a success rate of up to 90%–10% being lost from different spelling or ambiguous of language.","PeriodicalId":273911,"journal":{"name":"2017 14th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114538503","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both batteries reached up to 3.9 V within 40 minutes and both batteries were able to charged approximately 17 % faster than the conventional Constant Current-Constant Voltage (CC-CV) charger. The proposed system gave 6 % and 5 % of leading charge efficiencies than CC-CV strategy, for Li-ion and Li-Po batteries respectively.

This converter is suitable for industrial applications that require high voltage and power. A four-phase high-frequency transformer is used for isolation and increasing voltage. The most important feature of this converter is reducing current ripple of the power source. Moreover, the proposed converter considerably decreases the load voltage ripple. The current passing through the switches and passive elements is low, too. The converter is analyzed in four regions. Each of these regions is distinguished by the maximum number of switches that are simultaneously turned on in each switching period. Finally, the accuracy operation of the proposed converter is reconfirmed by the simulation results.","PeriodicalId":273911,"journal":{"name":"2017 14th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133001700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reason to use linear regression because of in experiment amount of A&B solution or nitric acid that adding to reservoir effect to increasing number of EC or pH in the same direction. For EC and pH adjusting equation use 3 variables are target (output), EC or pH measurement (input), and amount of A&B solution or Nitric acid (control process).

Many systems are proposed to solve this problem, for example, Intelligent Transportation System(ITS). In general, ITS consists of many subsystems including traffic monitoring. The monitoring system can provide the information of vehicles that pass through the monitoring area. This information can suggests about the status of the traffic. For this reason, developing a system that can classify vehicle with high accuracy plays important role to support ITS. The proposed system of vehicle classification using neural network presents in this paper includes other techniques i.e. vehicle detection and vehicle occlusion handling. Furthermore, Back-propagation neural network and Radial basis function network are implemented for vehicle classification. The training dataset of these two neural network classifiers is taken from a traffic video while the testing dataset is taken from another traffic video. The experimental results show that both techniques can classify vehicles only 71% accuracy because the different size of detected vehicles in those two videos. In order to solve this problem, affine transform function is implemented to scale the object of the testing video. After implementing affine transformation to the system, the accuracy of Back-propagation technique increases to 86% while Radial basis function remains the same. The experimental results illustrate that Back-propagation neural network can classify vehicles with higher accuracy and better performance than Radial basis function network.","PeriodicalId":273911,"journal":{"name":"2017 14th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON)","volume":"89 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133110521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Volt/VAR control is used in solar inverter of PV farm to improve power quality and also reduce the disconnection of solar inverter caused by overvoltage. So, the owner of PV farm will get more opportunity to sell solar electricity back to the grid. For Volt/VAR control, solar inverter with PQ mode is used to control the active and reactive power of the system. Electricity data from substation are sent to PLC based upon IEC 61850, which is the standard communication of electrical substation system.
