In this proposed control algorithm the discrete nature of the power converter are utilized and predicts the future behavior of the input system variables.

The proposed predictive control algorithm is validated through simulation and shows potential control and tracking of input unity power factor.","PeriodicalId":436232,"journal":{"name":"2013 IEEE International Conference on Circuits and Systems (ICCAS)","volume":"254 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115103393","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 objective is to develop a means to distinguish between fresh milk and spoilt milk. An electronic tongue (e-tongue) with a pH sensor has been implemented together with a graphic user interface. The definition of fresh milk was established and the e-tongue was used to measure both pasturised and non-pasturised milk in different conditions (fresh/spoilt). Based on the experimental results, we conclude that the pH parameter is not suitable as a sole indicator of milk freshness. Additional measurement using e.g. carbon dioxide sensor is required.","PeriodicalId":436232,"journal":{"name":"2013 IEEE International Conference on Circuits and Systems (ICCAS)","volume":"658 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122960217","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 contrast to previously reported works, the proposed macromodel accounts for fringing field effects and relies on a novel and more accurate beam profile. As a result the proposed macromodel exhibits a capacitance error of only 3.2% and a 50% improvement in deflection accuracy compared to prior works.","PeriodicalId":436232,"journal":{"name":"2013 IEEE International Conference on Circuits and Systems (ICCAS)","volume":"322 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115840641","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}

Two error coding schemes namely, Joint crosstalk avoidance and Triple Error Correction (JTEC) and JTEC with Simultaneous Quadruple Error Detection (JTEC-SQED), provide both crosstalk reduction and multi-bit error correction/detection features. The available undetected error probability model yields an upper bound value which does not give accurate estimation on the reliability provided. This paper presents an improved mathematical model to estimate the undetected error probability of these two joint coding schemes. According to the decoding algorithm the errors are classified into patterns and their decoding result is checked for failures. The probabilities of the failing patterns are used to build the new models. The improved models have less than 1% error with respect to the simulation results and reflect in up to 60% higher mean time to failure as compared to available models.","PeriodicalId":436232,"journal":{"name":"2013 IEEE International Conference on Circuits and Systems (ICCAS)","volume":"434 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116733921","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}
