Its title is based on the title of a 1894 paper by Prof. W.E. Ayrton and his student H.C. Haycraft. They described a new and simplified method of measurement to improve the teaching of their underlying topic, and that is the goal of this paper. In the work described here, the measurand is taken to be an equation representing an alternating signal, and the declared values of the measurement are estimates of the parameters of the equation. It is shown that the parameters of the ac signal can be found by curve-fitting. Lessons can be drawn about the role of noise in measurement and about the very meaning of the result.","PeriodicalId":102691,"journal":{"name":"2016 57th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125711350","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 possibilities of independent work of companies and cooperation for more benefits are also reviewed. As possibility of distributing the additional profit in the case of coalition, the methods of the cooperative game theory are used. In this paper the authors examine and compare the options of the formation of coalitions, compare the selected alternatives and analyze the possible profits of the market participants in the case of different models of behaviour.

Cyber-physical systems have a huge potential in healthcare for improving treatment quality and patients' assistance speed. Cyber-physical systems will help automatizing treatment process that can be realized by the continuous monitoring of each patient's health state, and if necessary, using multiple medical devices. That allows gathering information about patient's health and perform operations on patients, in order to reduce the progressions of a disease and improve patient's healing process. The aim of article is to research cyber-physical system abilities, CPS application in medicine, and develop centralized healthcare cyber-physical system architecture concept.

The production laboratory is established on the basis of ≪Automated Power Systems≫ department, Ural Power Engineering Institute, UrFU. In the laboratory, the following processes are organized: designing, 3D printing of models and 3D laser scanning of power equipment installed at substations. Laser scanning of power facilities allows to achieve the priority goal, namely to obtain three-dimensional primary digital CAD-models and drawings of high accuracy, which are necessary in order to meet the challenges of designing, construction, quality control, diagnostics, and other engineering tasks. Applied to electric power system kit, laser scanning is used to improve the quality of basic data needed for the creation of 3D drawings of equipment and creation of printed models on the basis of CAD-scale models. At the present moment, the problem set is to accomplish the reverse engineering of 110/20 kV step-down transformer, using up-to-date methods of 3D laser scanning. On the basis of the data obtained, the transformer CAD-model of high accuracy is crested in accordance with the initial dimensions.","PeriodicalId":102691,"journal":{"name":"2016 57th International Scientific Conference on Power and Electrical Engineering of Riga Technical University (RTUCON)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127990084","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}
