Each of these zones has the form axisymmetric body. Axis of symmetry of each zone coincides with that of concentrator which passes perpendicularly through the center of focal area. Each zone of reflecting surface ensures homogeneous illumination of the entire focal area and the number of reflected beams incident in each point of focal area equals to the number of zones. The theory of this type of microconcentrators has been developed. General system of equations for reflecting surface profile makes it possible to design microconcentrators of one type having various combinations of concentration ratio, concentrator height and efficiency. Four possible design options for one of such zones have been described, as well as those of multi-zone concentrator structures. Specific features of various microconcentrator design options have been analyzed with regard to optimal variant selection for CPV modulesе with required parameters.This work is dedicated to parabolotoric microconcentrators with homogeneous illumination distribution in focal area.

The market provides a plethora of home automation protocols and technologies, with the end user having a difficult decision as to which of these is the most appropriate. Unfortunately, such a decision is a complex, time- consuming task, as technology solutions are changing over the years. The existing standards and protocols do not provide always enough information for the extraction of the appropriate metrics for comparing their technical characteristics and capabilities. This paper is an effort to present a complete information set about the most popular home automation protocols and technologies including standardized, proprietary and open source implementations. In addition, an approach from the end user's perspective is given, by providing critical details for administrators about their management and configuration procedures. Finally, the last section of this paper presents for each protocol its realization according to the OSI 7-layer model, in an effort to extract their common characteristics and differentiations.","PeriodicalId":186251,"journal":{"name":"TECHNOLOGIES AND MATERIALS FOR RENEWABLE ENERGY, ENVIRONMENT AND SUSTAINABILITY: TMREES19Gr","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133327955","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}
