The fully relativistic multi-configuration Dirac-Fock method taking into account both the correlations within the n = 4 complex and the QED effects has been used for the calculations. The obtained results are compared to those done by Hartree-Fock method and agree well with recent electron-beam ion-trap measurements. This has led to an accurate determination of scaling factors for the Slater and spin-orbit integrals calculated by the Hartree - Fock method. Predicted wavelengths and line strengths are given for Ag XIV. Results for fine structure energy levels and oscillator strengths and transition probabilities, life time, cross section and transition wavelengths (λ) are listed for all strong E1, E2 and M1 transitions among the 38 levels of Ag XIV ion.","PeriodicalId":142369,"journal":{"name":"2020 International Youth Conference on Radio Electronics, Electrical and Power Engineering (REEPE)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117020480","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}

Harmonic emission, mostly caused by non-linear loads, may lead to different well-known negative effects. However, some consumers are not able to operate with zero-emission, which leads to some consensus when a part of this emission to the grid is allowed. In order to compare the normalized and actual emission levels, and for quantitative assessment, in IEEE's and different national standards (in Russian Federation, USA, and EU countries, etc.), it has been introduced a factor named total harmonic distortion factor (THD). This paper outlines an approach for THD calculation, based on the operator-matrix state variable method (OMSV method).","PeriodicalId":142369,"journal":{"name":"2020 International Youth Conference on Radio Electronics, Electrical and Power Engineering (REEPE)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124848177","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}

Difficulties of calculations at the occurrence of large disturbances and analysis of the obtained results quickly increase with the increase of the number of elements of power systems, which cause in steady and transient modes various phenomena and accompanying processes, which cannot be analyzed without taking various kinds of equivalence. Therefore, it is generally advantageous to simplify power grid schemes in a stability analysis. In action, it is sought to obtain a scheme that reduces the number of elements involved, but at the same time allows for sufficiently reliable and practically foreseeable results. Because the problem of building models that best reflect actual processes is always relevant. This article deals with the proposal for system equivalence in relation to the Electrical power system (EPS) of the Kyrgyz Republic (KR).","PeriodicalId":142369,"journal":{"name":"2020 International Youth Conference on Radio Electronics, Electrical and Power Engineering (REEPE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129092718","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 present a new method for robot path planning in a static environment. The main aim; to tackle path planning in simple and fast method, seeks to satisfy many robot movement's requirements such as shortest path length, safety, smoothness with less time consuming. This method ensures that safety and smoothness criteria are already met, path length is then shortening the usage of environment details, where each point of this path can be seen only by its previous and next points. The obtained result is compared with the well-known methods and shows the superiority in simple and complex environments in term of time, smoothness and safety and the obtained path lengths are shorter than those obtained with PSO and ABC as well.","PeriodicalId":142369,"journal":{"name":"2020 International Youth Conference on Radio Electronics, Electrical and Power Engineering (REEPE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117228562","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}

Traditional electromagnetic (EM) analyses based on a uniform plane wave incidence were augmented by advanced numerical techniques to investigate the impact of the dichroic mirror on the overall antenna performance. The irregularity of the proposed FSS is introduced in varying aperture (unit cell) dimensions in one of the coordinates to minimize the energy losses at high frequencies. The optimal shape of a periodic cell is determined and characterized by the presence in the frequency response dual transmission poles in uplink/downlink bands, corresponding to the frequencies of reception and transmission in the Ka-band. Due to the varying cell grid structure the averaged losses over the entire range of incidence angles from 16° to 44° with an amplitude decay of the real source to the FSS edges were 0.06 dB, so this is acceptable attenuation for such structures.","PeriodicalId":142369,"journal":{"name":"2020 International Youth Conference on Radio Electronics, Electrical and Power Engineering (REEPE)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125894258","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}
