If the machine is switched accordingly, the corresponding slope of current varies with the increase and decrease of the inductance profile of the machine. The switching frequncy of SRM greatly varies in accordance to consequence of current chopping if the machine oprates in that mode. This paper addresses a welldefined and simple methodology of selecting an optimal optimal switch on angle within a low inductance region to reduce the switching frequency of SRM. Hence switching power loss can also be reduced which minmises the converter losses of SRM. The simulations are carried out in MATLAB/Simulink environment.","PeriodicalId":172583,"journal":{"name":"2021 6th International Multi-Topic ICT Conference (IMTIC)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133091112","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 simulation is organized in MATLAB, and the results for an aircraft's pitch angle reaction are shown by step response. PID, as well as LQR controller, includes the settings that may be manually adjusted or improved using genetic algorithms for improved performance and control. Genetic Algorithm-subject of global optimization, is a useful tool for solving a variety of issues.

The emergence of advanced HVDC systems is so rapid that they are replacing their counterpart HV AC systems in many parts of the world. In this paper, the prominence of modern HVDC power transmission systems is highlighted. The topologies, converter assortments, contrasts, and modeling methods are discussed. The renewable energy sources (RES) including solar photovoltaic (PV) parks and mainland/ onshore/ offshore wind farms can be assimilated into the existing AC grids via advanced HVDC converters.

Recent advancements in the field of data mining on English Corpus provided the opportunity to automatically classify the text from different sources into broad categories. However, due to the lack of Urdu language resources, less attention has been paid to classifying text written in Urdu. Urdu is one of the most commonly spoken languages in Asian countries and also a national language of Pakistan. Urdu is a morphologically rich language, contains special diacritics, and free word order which makes it a difficult task for automatic text classification. In this work, we introduce the fine-tuning BERT architecture for the classification of Urdu headline news. Also, perform Logistics regression (LR) and multilayer perceptron (MLP) with Bert features. The proposed model classifies the Urdu headline news based on their predefined labels. We performed extensive experiments on Urdu news dataset iNLTK.

H. Mirjat, Shoaib Ahmed Khatri, Bilal Aslam","doi":"10.1109/IMTIC53841.2021.9719739","DOIUrl":"https://doi.org/10.1109/IMTIC53841.2021.9719739","url":null,"abstract":"Electricity crises are gripping Pakistan day by day with scarcity of conventional resources, higher import bill and increased Transmission and Distribution (T&D) power losses. Apart from the first two challenges, averting T&D losses could greatly help the country to cope-up with the crises. The aggravated T&D losses in the system are mainly due to use of decades old system and the alone use of High Voltage AC Transmission (HVAC) technology for the transmission of electrical power. Such huge power losses in HVAC transmission system compels the country to consider other alternatives to transmit electrical power. One of such alternatives is the deployment of flexible alternating AC transmission system (FACTS) devices in the existing old HVAC transmission system, whereas the other one is emerging High Voltage DC (HVDC) transmission system which also seems to be a feasible alternative now. Pakistan has already undertaken initiative to establish its first bipolar 660KV Voltage Source Controlled HVDC link from Matiari-Lahore that evacuates 4000MW of power from southern region and transmits over the 886Km transmission line to the central load centers of the country. This study undertakes the comparative analysis of power losses in both HVAC and HVDC transmission systems by modelling both the systems using Power System Computer Aided Design Software (PSCAD) where the power transfer capability and transmission distance have been taken common in both the networks. The study results reveal that over 886Km and 2174MW of power transfer, HVAC system has power loss to 504.28MW which is around 23.2%, whereas HVDC system losses are 235.46MW which are around 10.8%. Thus, the comparative analysis depicts that HVDC has 268.88MW less power loss which is 12.4 % less than that of conventional HVAC system. It is concluded from this study that Pakistan's initiative to establish HVDC system is timely, and country should consider expanding HVDC system over HVAC system in near future to attain energy security.","PeriodicalId":172583,"journal":{"name":"2021 6th International Multi-Topic ICT Conference (IMTIC)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129924944","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}
