A single slot is a time span that can be assigned to a task, which is a part of a parallel job. The job launch requires a co-allocation of a specified number of slots starting and finishing synchronously. Some existing algorithms assign a job to the first set of slots matching the resource request without any optimization (the first fit type), while other algorithms are based on an exhaustive search. In this paper, we refine a general first fit resources selection algorithm by incorporating a special slots subset allocation procedure. The improved algorithm provides an optimal solution for a considered scheduling problem and maintains a reasonable computational complexity. The algorithm is compared with two common resources allocation heuristics and its optimization efficiency is proved by a simulation study against time, cost and general-case criteria.","PeriodicalId":365584,"journal":{"name":"2018 IV International Conference on Information Technologies in Engineering Education (Inforino)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122097672","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}

As a means of solution, computer simulation (CS) is used. To achieve specified quality indicators, the system approach to design and modern principles of structural and algorithmic optimization of VSI are used as the methodological basis. In particular, a high-frequency two-channel push-pull step-up DC/DC converter (SUDCC) with a patented energy-saving snubber and an energy-efficient strategy of the pulse-width modulation (PWM) in the VSI are used. For reasons of improving reliability and improving the energy and mass-dimensions, VSI is also performed on a two-channel structure. With the same considerations, the function of regulation (stabilization) of the output voltage is assigned to the converter. The SUDCC is also partly involved in improving the spectral composition of the output voltage. Estimates are given for the mass-size and energy parameters of the synthesized device.","PeriodicalId":365584,"journal":{"name":"2018 IV International Conference on Information Technologies in Engineering Education (Inforino)","volume":"489 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115990868","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}

Currently mostly all applied software systems support optimization procedures in a very limited form. This fact leads to several problems: black-box effect (i.e., there is no opportunity to explore source code, modify it, or simply verify), no code reuse (i.e., implemented procedures are accessible only within software that includes it), limitation modern optimization algorithm application (i.e., number of optimization algorithms increases but most of them were verified only on synthetic tests). Also, it should be noted that all mentioned problems lead to so-called reproducibility crisis. The main idea of this work is to suggest an Open-Source Optimization Library Extremum (OSOL Extremum) with wide API features and to show how it can be applied to find optimal control of a Simulink model that represents behavior of a satellite.","PeriodicalId":365584,"journal":{"name":"2018 IV International Conference on Information Technologies in Engineering Education (Inforino)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116190560","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}

By checking of generator stator circuit cables for thermal endurance the thermal effect time is the short circuit clearance time by the operation of the main protective equipment and the current is the short circuit current from the electric power system or the generator. The goal of this paper is to adjust the cable choice method in a stator circuit of a low-power generator inbuilt in the existing nodes of the electrical power system as a distributed generation object. By thermal endurance check of stator circuit installations for such generators the short circuit reference point may be on the adjoined segment of the electrical grid. In this case, by electrically close short circuits and after their clearance without disconnection of the generator from the power grid an additional current rush and asynchronous operation current will increase the thermal generation. Recommendations for refinement of cable thermal endurance check method were developed for a gas turbine low-power generator, which operates parallel to the electric power system.","PeriodicalId":365584,"journal":{"name":"2018 IV International Conference on Information Technologies in Engineering Education (Inforino)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132896321","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}
