Electrical DC-discharge plasma though micro air-bubbles water was investigated by current and voltage probe. The yields from electrical discharge plasma in the water were measured by detecting of pH, conductivity, ozone (O3), nitrate (NO3-), and hydrogen peroxide (H2O2). During underwater discharge plasma with mixture of micro air-bubbles in water condition, the maximum voltage and current were applied approximately 5 kVp and 1 Ap, respectively. The chemically reactive species concentrations of water were measured as a function of treatment time for 4 minutes.

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}

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}

In order to properly deal with thermal errors and resultant thermal deformation, continuous precision thermal monitoring along the ball screw shaft is required. However, the working temperature of the ball screw shaft is difficult to measure online. Therefore, in this paper we propose a soft sensor based on an extreme learning machine (ELM) method for predicting the distributions of temperature rises on the ball screw shaft of a feed drive. ELM is an emerging learning algorithm for single-hidden layer feedforward neural networks (SLFNs) training that has recently attracted many researchers' interest due to its impressive generalisation performance at fast training speed. The performance of the ELM soft-sensor is investigated on the thermal expansion process of the ball screw system simulated by the finite element method (FEM). The results show that the ELM-based soft sensor provides good generalisation performance with much faster speed than the traditional backpropagation artificial neural network (BP-ANN).","PeriodicalId":6628,"journal":{"name":"2018 International Electrical Engineering Congress (iEECON)","volume":"8 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":"85688621","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}
