This paper considers a new configuration of hybrid broadband filter for power quality management in three-phase four-wire low voltage power systems. The proposed hybrid filter is composed of a single-phase power converter and the broadband passive filter connected in series. The hybrid filter can be operated in both passive and hybrid mode. The compensating performance of the filter is confirmed with computer simulation using MATLAB software. Analysis and simulation proved that the hybrid filter is an effective solution for neutral current mitigation.","PeriodicalId":448354,"journal":{"name":"Proceedings of the Russian higher school Academy of sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129068318","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 idea of the optimal fleet assignment and Flight Scheduling problem considered in this paper is to find a scheduling control method that minimizes the losses of the airline company from aircraft schedule disruptions. The problem is NP-complete and cannot be solved accurately for any real-life number of dimensions. An efficient parametric algorithm is proposed for finding an approximate solution of the problem. The proposed algorithm is an extension of the schedule optimization algorithm for a system of unrelated parallel machines with job release dates, which is based on the makespan criterion (Cmax). A substantial example is presented of applying the algorithm, as well as statistics of testing it on the data of a generating problem by the Cmax criterion.","PeriodicalId":448354,"journal":{"name":"Proceedings of the Russian higher school Academy of sciences","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127257600","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 particular, transport processes in nanofluids, their viscosity and thermal conductivity are not described by classical theories. At present the molecular dynamics (MD) method is widely used to model transport processes in nanofluids. This method, in its turn, requires knowing appropriate interaction potentials. To stabilize nanofluids, in particular, to prevent aggregation of nanoparticles sur-factants are used. In addition to homogeneous nanoparticles, composite nanoparticles are of great practical interest. The purpose of this paper is to construct interaction potentials of surfactant coated nanoparticles and composite ones with each other and with molecules of the carrier medium. A nanofluid consisting of a carrier fluid (gas or liquid) and surfactant coated nanoparticles or composite ones is considered. The particles are assumed to be solid and spherical. The interaction between the atoms of the nanoparticles and molecules of the carrier medium is described by Len-nard-Jones potentials with the appropriate parameters. Also, Lennard-Jones potentials describe the interaction of atoms of two nanoparticles with each other. The interaction potential of a mole-cule of the carrier medium with this nanoparticle is given as a sum of the potentials of this mole-cule with all the atoms of the nanoparticle. Similarly, the interaction potential of two nanoparticles is determined. In both above cases, the solid is approximated by the continuum model. The potentials obtained are intended for modeling of transport processes in nanofluids containing surfactant coated nanoparticles and composite ones as a dispersed element and their flows. kinetic theory fluid laminar-turbulent mathematical","PeriodicalId":448354,"journal":{"name":"Proceedings of the Russian higher school Academy of sciences","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124772289","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}
