Solar photovoltaic\u0000 cells convert solar energy into electricity through solar photovoltaic (SPV)\u0000 effect. Generated DC voltage then converted in to AC voltage by pump\u0000 controller, this AC voltage is used as the input of Variable Frequency Drive\u0000 (VFD). The VFD acts as a motor controller that controls the submersible pump\u0000 motor by varying the frequency and voltage of its input power supply. The\u0000 VFD is associated with pump controller. Regulated three phase AC voltage is\u0000 the output of the pump controller which is directly connected with\u0000 submersible pump. The water thus drawn from bore wells by a solar water pump\u0000 is pumped to supply for irrigation purpose as required. This system is full\u0000 off-grid interfaced system appropriate for the village areas. The main goal\u0000 of this system is to use solar energy at a minimum running cost. The solar\u0000 powered project is completely eco friendly and the plant is relatively clean\u0000 with small maintenance. This project helps to reduce the cost of\u0000 electricity, as well as minimize the overall agricultural cost.","PeriodicalId":44296,"journal":{"name":"Facta Universitatis-Series Electronics and Energetics","volume":"47 3 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76171939","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}

It has the advantage of computing\u0000 at a faster speed, consuming lower power, and work at Nano- Scale. Besides\u0000 these advantages, QCA logic is limited to its primitive gates, majority\u0000 voter and inverter only, results in limitation of cost-efficient logic\u0000 circuit realization. Numerous designs have been proposed to realize various\u0000 intricate logic gates in QCA at the penalty of non-uniform clocking and\u0000 improper layout. This paper proposes a Composite Gate (CG) in QCA, which\u0000 realizes all the essential digital logic gates such as AND, NAND, Inverter,\u0000 OR, NOR, and exclusive gates like XOR and XNOR. Reportedly, the proposed\u0000 design is the first of its kind to generate all basic logic in a single\u0000 unit. The most striking feature of this work is the augmentation of the\u0000 underlying clocking circuit with the logic block, making it a more realistic\u0000 circuit. The Reliable, Efficient, and Scalable (RES) underlying regular\u0000 clocking scheme is utilized to enhance the proposed design?s scalability and\u0000 efficiency. The relevance of the proposed design is best cited with coplanar\u0000 implementation of 2-input symmetric functions, achieving 33% gain in gate\u0000 count and without any garbage output. The evaluation and analysis of\u0000 dissipated energy for both the design have been carried out. The end product\u0000 is verified using the QCADesigner2.0.3 simulator, and QCAPro is employed for\u0000 the study of power dissipation.","PeriodicalId":44296,"journal":{"name":"Facta Universitatis-Series Electronics and Energetics","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72576532","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, the amount of data that should be inspected imposes a great challenge to IDSs. With recent emerge of various big data technologies, there are ways for overcoming the problem of the increased amount of data. Nevertheless, some of this technologies inherit data distribution techniques that can be a problem when splitting a sensitive data such as network data frames across a cluster nodes. The goal of this paper is design and implementation of Hadoop based IDS. In this paper we propose different input split techniques suitable for network data distribution across cloud nodes and test the performances of their Apache Hadoop implementation. Four different data split techniques will be proposed and analysed. The techniques will be described in detail. The system will be evaluated on Apache Hadoop cluster with 17 slave nodes. We will show that processing speed can differ for more than 30% depending on chosen input split design strategy. Additionally, we?ll show that malicious level of network traffic can slow down the processing time, in our case, for nearly 20%. The scalability of the system will al so be discussed.","PeriodicalId":44296,"journal":{"name":"Facta Universitatis-Series Electronics and Energetics","volume":"57 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77839644","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 challenges lie in achieving sufficiently good absorption over a broad range of frequencies. Considering the applications in airborne and handheld devices where light weight, thin, conformable and broadband absorbers are desired, numerous techniques and methods are applied to design broadband absorbers. In this review paper, a detailed analysis on electromagnetic absorbers including evolution, the materials used, and characteristics such as absorption efficiency over the years is presented. Progress on recent research on various polymer- based and metamaterial- based microwave shields are included along with their findings. Several prospects such as broadbanding, flexibility, multibanding are described here. Various material and structural composition offering good absorption performance in different frequency bands are also summarized whose the techniques can be used for suppressing electromagnetic interference and radar signature. The paper specifies the aspects one encounters while designing and realizing a perfect microwave absorber. Explored here are several works of distinguished authors which are based on various techniques used to achieve good absorption performance with ease of mounting.","PeriodicalId":44296,"journal":{"name":"Facta Universitatis-Series Electronics and Energetics","volume":"32 5","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72462195","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 DG penetration changes the single power source to multiple power sources and bidirectional load flow which enhances the system reliability and reduces system power losses. The particle swarm optimization and gravitational search algorithm are implemented for the optimal siting and sizing of one and three DG units in the RDS to examine its impact on system reliability and loss reduction. The types of DGs considered are Type I (injects real power) and Type IV (injects reactive and real power). The constant power is the chosen load model. The reliability indices taken for the analysis of system reliability are Average Energy Not Supplied, Total Energy Not Supplied and Average System Interruption Duration Index. The efficacy of the proposed method is validated on 33-bus in the presence of single and multiple DGs. The significant decrease in system power losses with the upgraded bus voltage profile, system reliability and remarkable annual loss saving is analyzed for Type IV DG over Type I DG. The results determined are compared to other meta-heuristic approaches as well as analytical techniques to demonstrate the superiority of the proposed methodology. The results are also statistically verified.","PeriodicalId":44296,"journal":{"name":"Facta Universitatis-Series Electronics and Energetics","volume":"60 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90207861","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}
