Multiport converters occupy an increasingly important role in energy conversion systems. A proper design of these converters according to the needs of the energy system leads to lower costs with energy conversion and increase the energetic efficiency. The designed multiport converter is two inputs and one output. The structure of multiport power converter contains two DC-DC buck converters. Experimental results lead to improved electronic converter circuit.","PeriodicalId":122809,"journal":{"name":"2016 8th International Conference on Electronics, Computers and Artificial Intelligence (ECAI)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123348924","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 make the IT service management more effective especially the configuration management, the manager needs the appropriate and ad-hoc analysis for decision making. Our approach proposes a knowledge base to accompany the conventional database system in order to flexibly cope with the strategic problems. An ontology schema is designed to handle the configuration management of IT service resources in term of RDF N-triple. The classes and hierarchy of the schema are provided along with the appropriate property relations among the configuration items. We design the queries by SWRL & SQWRL rules for IT service functions, such as how to allocate the budget for the annual maintenance fee, etc. The Protege software is used during our ontology schema design. We develop a Java web application with Jena Framework along with the Jena Fuseki ontology server to successfully demonstrate our ontology-based approach.","PeriodicalId":122809,"journal":{"name":"2016 8th International Conference on Electronics, Computers and Artificial Intelligence (ECAI)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125150439","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}

Their application in industrial control systems (ICSs) is also growing rapidly as modem ICSs increasingly use open standard protocols instead of proprietary. Due to an ever changing threat landscape, the rulesets used by these IDSs have grown large and there is no way to verify their precision or accuracy. Such broad and non-optimized rulesets lead to false positives and an unnecessary burden on the IDS, resulting in possible degradation of the security. This work proposes a methodology consisting of a set of tools to help optimize the IDS rulesets and make rule management easier. The work also provides attack traffic data that is expected to benefit the task of IDS assessment.","PeriodicalId":122809,"journal":{"name":"2016 8th International Conference on Electronics, Computers and Artificial Intelligence (ECAI)","volume":"216 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134223856","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}

Constraints applied may be both fixed, that are initially established with rigorous formulation, and probabilistic, in which case the process becomes an adaptive one, using statistical properties of the input symbols. Using fixed constraints, one can determine the fixed probabilities of appearance for letters or words and using probabilistic constraints one can determine the relationships between letters or words in a row by building lists of probabilities containing conditions allowed for transitions that are based on certain letters prefix or reference to a particular word. In order to illustrate the usefulness and applicability of these constraints predictive techniques of text insertion will be presented, as well as how they are implemented in applications such as predictive keyboard for smartphones or portable devices.","PeriodicalId":122809,"journal":{"name":"2016 8th International Conference on Electronics, Computers and Artificial Intelligence (ECAI)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133824920","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}

This solution of using one input — two outputs current amplifiers represents the edge of this proposed generation method. Theoretically such current amplifiers can be easily obtained, using current-conveyors. From the transfer function of the oscillator I intended determination of errors introduced by the parameters that can be estimated and intervene in the gain expression (Go) and in the frequency of oscillation (ω0).

Normally EMI can be reduced by adding bulky filters to reduce the conducted EMI, by shielding for radiated EMI, by installing snubber circuits or by other methods. Some of these methods have the unwanted effect of decreasing efficiency of power converter. At the same time, the cost and the physical dimensions of the converters increase, especially if large values are used for the coils and capacitors of the input filter. Another technique to reduce EMI is to use the Spread Spectrum Power Converter (SSPC) that uses the Spread Spectrum Frequency Modulation (SSFM) technique for PWM command. This paper aims to evaluate the performance of spreading the SSPC power spectrum using five SSFM PWM command techniques.","PeriodicalId":122809,"journal":{"name":"2016 8th International Conference on Electronics, Computers and Artificial Intelligence (ECAI)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117276357","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}

Typically, a chatbot recognizes the audio from human and translates it to text, and then matches the text with sentences stored in advance in the database by means of measuring similarity. So far, English chatbots have done much better than Chinese ones, mainly for the reason that processing sentences in Chinese requires more sophisticated techniques than that in English. Considering the low efficiency and accuracy of the existing Chinese sentence similarity measure methods, we propose a novel method oriented for lexical similarity measure of Chinese sentences by means of Chinese sentence segmentation and weighted word matching. Based on this method, a Chinese AI chatbot is developed and tested under a variety of settings. Experimental results show that our proposed method can achieve satisfactory performance in various cases.","PeriodicalId":122809,"journal":{"name":"2016 8th International Conference on Electronics, Computers and Artificial Intelligence (ECAI)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115737144","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}
