In addition, TSP is considered as a NP-hard problem as well as an optimal minimization problem. Selection, crossover and mutation are the three main operators of GA. The algorithm is usually employed to find the optimal minimum total distance to visit all the nodes in a TSP. Therefore, the research presents a new crossover operator for TSP, allowing the further minimization of the total distance. The proposed crossover operator consists of two crossover point selection and new offspring creation by performing cost comparison. The computational results as well as the comparison with available well-developed crossover operators are also presented. It has been found that the new crossover operator produces better results than that of other cross-over operators.","PeriodicalId":226060,"journal":{"name":"2019 International Conference on Electrical, Computer and Communication Engineering (ECCE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131946351","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}

Particularly, due to the exposure to the open sky, Photo-Voltaic (PV) panels are highly susceptible to lightning that can damage the panels, DC lines, inverters and other equipment in the plant. To reduce this effect using a properly designed lightning protection system, in this paper, we investigate the induced voltage phenomena and its characteristics and effects on a large-scale solar power plant. The electromagnetic field and induced voltage in different places of the plant are measured by Virtual Surge Test Lab (VSTL) tool using Finite Difference Time Domain (FDTD) method. Varying characteristics of electromagnetic interference are analyzed for the soil resistance, lightning time, and lightning locations. Our early results verify that the electromagnetic field and induced voltage largely depend on the location of the lightning strike. The induced voltages are also found to vary with the increase of soil resistivity and lightning time. Presented findings would be helpful to the development of a sustainable, safe and effective large-scale solar power plant.","PeriodicalId":226060,"journal":{"name":"2019 International Conference on Electrical, Computer and Communication Engineering (ECCE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116460366","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}

DTN uses store-carry-forward approach where message travels from source to destination node through intermediate nodes by opportunistic contacts due to node movement. These intermediate nodes keep the message in their buffer, carry it while on the move and forward it to the next intermediate node encountered untill the message gets to reach its destination. An important application of DTN is considered to provide for emergency message delivery to key personnel in a disaster-stricken area. The main challenge of DTN is to adopt an appropriate routing technique to deliver messages in the most efficient way. In this work, we look into the performance of DTN routing techniques such as Epidemic, MaxProp, Spray-and-Wait, and Spray-and-Focus by considering the campus area of Rajshahi University as it is one of the key points of importance for higher education and research in Bangladesh. Our goal is to evaluate the performance of DTN routing techniques for emergency message circulation in the campus area of Rajshahi University in case of disaster when regular communication networks are not available. We use the Opportunistic Network Environment (ONE) simulator for the simulation of above situation. The performance of the DTN routing protocols is analyzed based on four criteria: delivery probability, transmission cost, average latency, and average hop count by varying the message size and the density of nodes. From the results obtained from simulation we see that Spray-and-Focus yields the best performance. On the other hand, Epidemic gives the worst performance in the campus area of Rajshahi University, Bangladesh with the given simulation settings","PeriodicalId":226060,"journal":{"name":"2019 International Conference on Electrical, Computer and Communication Engineering (ECCE)","volume":"03 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130668491","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}

Utilizing an ensemble learning method named Gradient Boosting (GB) our paper proposes a technique to previse future fault classes based on the data obtained from analyzing the recorded fault data. To demonstrate the cogency of the method, we applied it on the REB fault data provided by the Case Western Reserve University (CWRU) Lab.
