A parallel operation of three atmospheric non-thermal argon plasma jets was applied for leachate treatment with water sample in strong acidic condition $(mathbf{pH} < 2)$. Three cases with different gap distances for 1.5, 3 and 4.5 cm were employed with a $4.5 mathbf{kV}_{text{rms}}$ 50 Hz AC neon sign transformer power source for 60 minutes. In this time, the influence of electrode gap distance $(text{G}_{text{d}})$ of argon plasma jet on the degradation of refractory organic compounds in biotreated landfill leachate was observed. Some key parameters of water quality including pH, DO, temperature, COD and the macromolecules, such as humic and fulvic substances, were measured before and after treatment. The result showed that the maximum removal of COD (33.9%), fulvic (53.3 %), humic (32.2%), and visible humic substances (57.2%) was found with the operating condition in 4.5 cm $text{G}_{text{d}}$ case. It could be confirmed that atmospheric non-thermal Ar plasma had the potential to effectively reduce the refractory organic compounds in wastewater which could be exploited for post-treatment of biotreated landfill leachate.","PeriodicalId":6628,"journal":{"name":"2018 International Electrical Engineering Congress (iEECON)","volume":"56 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77876247","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}

Design and development of a vertical scanning system and a roll-motion stabilizing system for laser point-cloud data, measured radial distance horizontally, are implemented. By using an encoder to feedback a roll angle, the first DC servo motor with a PI controller can assist stabilizing horizontal point-cloud data. A four-bar linkage mechanism, driven by the second DC motor and controlled by a feedforward controller with Inertial Measurement Unit (IMU) pitch-angle feedback, could generate $pmb{pm 16.5^{circ}}$ up-and-down pitching motion of the laser scanner. Both digital feedback controllers of two motors are developed in an Arduino microcontroller. Kinematics model of the four-bar linkage mechanism are derived and simulated for a design purpose. Experimental tests of the first motor, controlled by the PI-controller, reveal robustness against external-force disturbances, acting on the laser scanner, and demonstrate a roll-motion counterweight of the mechanism base. In additions, experiments of the second motor with the feedforward controller can compensate for gravity to achieve periodical cycles of the four-bar linkage motion. Reconstructed 3D point-cloud surface from laser 2D cloud points can provide accurate horizontal width and smooth-continuous height of measured indoor wall.","PeriodicalId":6628,"journal":{"name":"2018 International Electrical Engineering Congress (iEECON)","volume":"26 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86956335","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 MEA and PEA substation uses lead acid type batteries for a de distribution using as a backup source. Therefore, a battery monitoring is a key function in a charger to check battery condition; however, a traditional charger used in a substation does not have this function. A lead acid battery first order equivalent circuit is utilized to analyze the battery condition by probing an internal resistance of a battery. A first order equivalent circuit is used to determined battery parameters using transient response analysis. PSIM is also used to simulate the proposed equivalent circuit properties comparing to experimental result. The experimental results are conducted by using three lead acid batteries which are used in a PEA substation. The travelling wave theory is also applied to determine the health of under tested batteries. Both simulation and experimental results show that the proposed technique is promising technique to implement in a charger function for detecting a battery condition as a proactive maintenance.","PeriodicalId":6628,"journal":{"name":"2018 International Electrical Engineering Congress (iEECON)","volume":"2937 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86524833","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}

Consequently, it is important especially when designing and developing a tool such as assistive technology tool for students with learning disabilities. Assistive technology is a tool that helps increase potential or improve capability of exceptional students, so that they will have more learning potential and hence they can study effectively. In addition, assistive technology can be used as a tool by teachers to facilitate learning management and provide learning opportunity to students. A Thai Word Search Keyboard Application was developed to help students with writing and spelling disabilities to be able to select the right vocabularies. Thai Word Search Keyboard Application, which was still a lab prototype, was tested for performance with teachers and related persons who had ever worked with students with learning disabilities. The researchers use a heuristic evaluation in this study. The evaluation result from functional requirement and usability tests was at a high level, while the result from functional tests was at a moderate level. Those results would be a guideline for improving the next version of Thai Word Search Keyboard Application.","PeriodicalId":6628,"journal":{"name":"2018 International Electrical Engineering Congress (iEECON)","volume":"1 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87181527","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}
