In NPC inverter topologies with more than three-level, the problem of charge balance in the split dc-link capacitors is still discussable. Hence, the most important advantage of the proposed pulse width modulation (PWM) control method is keeping the charge balance of capacitors in the neutral point (NP). To check the correct operation of the proposed PWM control method, the structure of conventional three-phase NPC five-level voltage-source inverter is also used. In this paper, different combinations of permissible switching states for five-level NPC inverter based on voltage-source is presented. Moreover, the control signals are explained for NPC five-level voltage-source inverter by using both conventional and proposed PWM control methods. In this paper, a comparison between conventional and proposed control methods is performed. The simulations performed in PSCAD software are done for both conventional and proposed PWM control methods. The good performance of the proposed control method compared to conventional control method is verified by the simulation results.","PeriodicalId":273911,"journal":{"name":"2017 14th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON)","volume":"116 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":"117269828","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}

As a result, the automatic suspect vehicle detection emerges as one of effective tools to tackle the problems. The law enforcement information and data generated by vehicle sensors are necessary to identify criminal or suspect vehicles that crossing the checkpoint. However, the traditional process is not effective and accurate. It is unable to classify the criminal or suspect vehicles if they are forged license plate or changed color, brand or type illegally. This paper proposes a new framework for automatic suspect-vehicle detection, with an improvement of illegal vehicle classification. It compares legal vehicle records obtained from Department of Land Transport (DLT) with those of vehicles crossing checkpoint. Also, DLT's legal vehicle records can be used to improve criminal or suspect vehicle detection. From extensive experiments, the results show that the proposed framework can increase the detection accuracy rate 27.51% beyond the traditional counterpart. In addition, the new system can detect illegal vehicles, criminal vehicles, and suspect vehicles although they are seen with forged license plates.","PeriodicalId":273911,"journal":{"name":"2017 14th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON)","volume":"47 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":"127531810","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}

To assist the sleep physician in evaluating of patients, a new automatic sleep stage classification system needs to be developed. So this is the aim of this work based on Electroencephalography (EEG) and Electrocardiography (ECG) for Sleep apnea patients. This article proposes two importance topics, the first is the new feature of EEG signal using a simple statistical technique and the results prove that the various sleep stages can be discriminated more clearly at significant levels (p<<0.05). Second, the dimension reduction is proposed based on the Canonical Correlation Analysis (CCA) technique that explores possible correlated multi-sources to improve the sleep stages classification at 95.42% accuracy by using random forest classification. The results show that our proposed method has ability to develop a new sleep stage classification assistance.","PeriodicalId":273911,"journal":{"name":"2017 14th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON)","volume":"52 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":"126823837","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}
