Nowa days, the usage of renewable PV source\u0000is increasing gradually, due to the encouragement of eco-friendly energy sources by providing subsidies for\u0000the installation in the initial states. In the agricultural sector, the water pump system requires a 3-ϕ power\u0000supply, for that we need a separate transmission line and transformers to meet the load demand. In this\u0000paper, a solar power fed BLDC motor water pumping system with boost converter and Voltage source\u0000Inverter (VSI) is presented which reduces the converter switch stress by increasing the voltage transfer gain\u0000ratio. VSI needs a huge dc link capacitor that is inherently unreliable and is one of the most expensive\u0000components of a drive.A MPPT controller is required to extract maximum power from the high penetrating\u0000renewable PV source and also proposes the Current source inverter (CSI) fed water pumping system is\u0000developed and examine with same operating conditions. A comparative analysis view in existing method of\u0000system replace the VSI with CSI. The performance of system is analyzed with speed settling times at same\u0000operating conditions. The proposed work is carried out in the MATLAB/Simulinksoftware. A comparative\u0000analysis is also presented in lucid manner","PeriodicalId":13741,"journal":{"name":"International Journal for Modern Trends in Science and Technology","volume":"9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90500778","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}

However, fast charging stations, especially super-fast charging stations may stress power grid\u0000with potential overload at peaking time, sudden power gap and voltage sag. This project discusses the\u0000implementation and modeling of space vector modulation to multiport converter based EV charging station\u0000integrated with PV power generation, and battery energy storage system. In this paper, the control scheme\u0000and combination of PV power generation, EV charging station, and battery energy storage (BES) provides\u0000improved stabilization including power gap balancing, peak shaving and valley filling, and voltage sag\u0000compensation. As a result, the influence on power grid is reduced due to the matching between daily\u0000charging demand and adequate daytime PV generation. Simulation results are presented to confirm the\u0000benefits at different modes of this proposed multiport EV charging circuits with the PV-BES configuration with\u0000SVM technique. Furthermore, SiC devices are employed to the EV charging station to further improve the\u0000efficiency.","PeriodicalId":13741,"journal":{"name":"International Journal for Modern Trends in Science and Technology","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82648899","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}

However,\u0000the production of Portland cement, an essential constituent of concrete, leads to the release of significant\u0000amounts of CO2, depletion of natural resources and environmental degradation. This paper investigates the\u0000compressive strength of concrete by replacing cement with GGBS and silica fume effect of glass fibers on\u0000performance of concrete is studied. In this present work a humble attempt had been made to evaluate and\u0000compare the compressive strengths of GGBS blended concrete cubes with controlled concrete cubes cured\u0000under sea water for 28 days. By conducting the tests on the cubes, conclusions were drawn after plotting\u0000and analyzing the results. Compressive strength test is conducted on the samples after 28 days. The\u0000optimum value is obtained at 15% replacement with GGBS and 5% with Silica fume. In this study again we\u0000trailed addition with Glass fibers with the percentage of 0.5%,1.0%,1.5%, compressive strength have been\u0000studied. Finally at 1.0% addition we get maximum strength compared to controlled mix.","PeriodicalId":13741,"journal":{"name":"International Journal for Modern Trends in Science and Technology","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72944416","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 challenge was not just to provide researchers with very rich publications at\u0000any time, any place and in any form but to also offer the right publication to the right researcher in the right\u0000way. Several approaches exist in handling paper recommender systems. However, these approaches\u0000assumed the availability of the whole contents of the recommending papers to be freely accessible, which is\u0000not always true due to factors such as copyright restrictions. This paper presents a collaborative approach for\u0000research paper recommender system. By leveraging the advantages of collab- orative filtering approach, we\u0000utilize the publicly available contextual metadata to infer the hidden associations that exist between\u0000research papers in order to personalize recommen- dations. The novelty of our proposed approach is that it\u0000provides personalized recommen- dations regardless of the research field and regardless of the user’s\u0000expertise. Using a publicly available dataset, our proposed approach has recorded a significant improvement\u0000over other baseline methods in measuring both the overall performance and the ability to return relevant and\u0000useful publications at the top of the recommendation list.","PeriodicalId":13741,"journal":{"name":"International Journal for Modern Trends in Science and Technology","volume":"21 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91434944","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}
