It can provide only the cloud cover index and cloud direction. It cannot give out the cloud base height or speed. In this paper, a pair of WSI is synchronized to capture stereo images. We propose a new rectification technique that is a part of WSI-installation which directly effects Cloud Base Height estimation. the semi-global matching technique is proposed to find matching points on both images. Triangulation can then yield the distance of the cloud base. Calibration and testing of the proposed system are done by comparing the distances of known buildings estimated by our analysis with the distances obtained by Google Maps. The average errors are about 4% for targets in the range of 150m, and 15% for targets in the range of 1km.","PeriodicalId":371552,"journal":{"name":"2020 17th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON)","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121358149","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}

STI is also highly related with listening difficulty and is a function of room impulse response (RIR). RIR is regarded as the transfer function between the sound source and the sound receiver, and is generally unknown and non-static. This paper proposes a scheme to limit the STI to ensure speech privacy by utilizing proportional-integral- derivative (PID) control with estimated STI as the feedback value. The scheme bypasses the measuring of RIR of the environment where the conversation is being carried out, and uses a STI- estimation method and a RIR model to ensure speech privacy. The scheme manipulates the speech signal in the way that its STI has the value of 0.3 or in an unintelligible band. The STI is limited by controlling one parameter of the RIR model by using a PID controller. The performance of the scheme is evaluated through objective and subjective tests. The results indicate that the scheme is able to provide speech privacy with an average error between the actual and target STIs of 0.01.","PeriodicalId":371552,"journal":{"name":"2020 17th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114745677","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}

Different configurations are explored including sparse and dense rewards combining with checkpoints, orientation reward and stay-in-collision punishment. It shows high success parking rate in a basic parking zone up to at more than 95%. For the more difficult parking zone, the model works better when each zone is trained separately.","PeriodicalId":371552,"journal":{"name":"2020 17th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124449287","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}

On the other hand, the authors successfully obtain the equivalent condition of ${mathcal{H}_infty }$admissibility criterion for SSMSs by introducing two slack variables. Also, because the proposed condition is expressed in terms of convex condition, i.e., linear matrix inequalities (LMIs), the result can be used to find the optimal ${mathcal{H}_infty }$performance even though the information about the transition rates is limited.","PeriodicalId":371552,"journal":{"name":"2020 17th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON)","volume":"2252 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130225833","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}

Normally, recruiters for information technology employment face the problem of matching appropriate candidates with available positions as they may have insufficient knowledge to determine whether candidate profiles are suitable. The requirements and demand for jobs may not be enough to advance the situation while matching skills and competence with job descriptions often preclude older candidates. This research is supported by the Thai Gerontology Research and Development Institute (TGRI). Herein, we present a solution involving data mart modeling and machine learning. In the data mart modeling, an extract, transform, and load (ETL) process that pulls data into a data mart (star schema) and then applies distance measures to calculate matching. Historical records of both the companies and older job seekers are kept in the data mart to understand behavior and keep track of data. Moreover, we collect disease information and map to ICD-10 code. This can help employers to find appropriate job seekers related to their skill sets and limitation of disease. We treat their skills as terms and employment positions as documents and then calculate the ranking of each job profile. The results show that the outcomes garnered from the distance measures are consistent and creditable.","PeriodicalId":371552,"journal":{"name":"2020 17th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131108078","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 RE generation consists of solar and wind generation while the conventional generation, which is considered as the dispatchable generation, consists of natural gas combined-cycle and coal thermal generation. In the analysis, a unit commitment is executed based on the operating costs, i.e. variable costs and load following costs of the dispatchable generation. Moreover, the proposed method is aimed to accommodate the electricity demand with the consideration of generation characteristics such as minimum generation, ramp rate, minimum uptime and minimum downtime. The result shows that the optimal renewable energy integration is at 40% of the total electricity demand. Beyond the optimal level, the dispatchable generation operating costs tend to be higher because of the RE compensation operation.","PeriodicalId":371552,"journal":{"name":"2020 17th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134473370","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}
