For a fair comparison, similar dimensions are used for both coils (diameter and cross section), in analytical and numerical modeling. The numerical modeling has been performed using the finite element COMSOL Multiphysics® software. The energy stored in a toroidal coil is compared with an equivalent cylindrical coil and is shown to be higher with 65% and 57% using the analytical and numerical modeling, respectively. Also, the results have highlighted an error of 21 % and 3.7% for the analytical modeling compared to the numerical modeling in case of cylindrical and toroidal magnetic coils, respectively.","PeriodicalId":285780,"journal":{"name":"2019 11th International Conference on Electronics, Computers and Artificial Intelligence (ECAI)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129435528","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}

Comparison with series-series compensation shows that the proposed topology is an equal substitute for the latter, in terms of output power, when operating at the natural resonant frequency. Simulation results validate the detailed theoretical analysis, suggesting that this is a promising alternative for contactless chargers for medical applications.","PeriodicalId":285780,"journal":{"name":"2019 11th International Conference on Electronics, Computers and Artificial Intelligence (ECAI)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128065142","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}

However, due to the relatively high costs, automated visual inspection is applied only for the final product and not after each production phase. Faulty products are identified at the end of the production pipeline, little information is provided with regard the causes and the production phase that produced the defect products. This paper presents a deep CNN for the enhancement of the computer vision system by providing additional information on the type of the product and consequently on the production phase that generated that product, and fault, respectively. The CNN has been integrated into the pipeline for the automated process control. This information is important for further decision makings in production flow management. The paper presents full description of the deep CNN model design with discussions based on image analytics carried out on 12k database of images of products from the porcelain industry.","PeriodicalId":285780,"journal":{"name":"2019 11th International Conference on Electronics, Computers and Artificial Intelligence (ECAI)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124541186","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}

Indeed, the questions arise about the preferred configuration to use (AC coupled or DC coupled), the storage devices to adopt, and the control strategy to apply. A hybrid Energy Storage System (ESS) using batteries and supercapacitors (SC) seems to be a good device to answer the second constraint. The objective of the paper is to study the influence of the control strategy for a hybrid ESS using DC coupled configuration and the control strategy for ESS only composed of SC using AC coupled configuration.","PeriodicalId":285780,"journal":{"name":"2019 11th International Conference on Electronics, Computers and Artificial Intelligence (ECAI)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131506217","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 this paper we are presenting the design of a simple MPPT (Maximum Power Point Tracker) charge controller based on perturb and observe algorithm embedded into Atmega 2560 microcontroller. The voltage of the solar cell that operates at its maximum power point at 25C°, which is the standard temperature for testing, is higher than the voltage of battery. While solar panel temperature goes down, the voltage goes up. Therefore, the microcontroller with the MPP algorithm is able to capture the surplus energy and inject it into the accumulator. So, during the colder periods of the year (or the day), a MPPT controlled solar panel can generate up to 30% more energy than during warmer periods. The charge controller will use the microcontroller, DC-DC buck boost circuit, sensors that will read the electrical information from the photovoltaic panel and the battery.","PeriodicalId":285780,"journal":{"name":"2019 11th International Conference on Electronics, Computers and Artificial Intelligence (ECAI)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124144093","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}
