They are necessary for carrying a variety of ocean traces across the ocean. Eddy detection is one of the most active fields of physical oceanographic research. Although it is a new trend, using deep learning algorithms to find eddies is still in its early stages. The different sizes and shapes of eddies make automatic eddy segmentation challenging. U-Net makes a dense prediction to solve this problem. However, the network architecture is very intricate. In this paper, a dilated convolution U-Net is developed for the semantic segmentation of ocean eddies using sea surface height data. This technique decreases architectural complexity without sacrificing performance. Further, a new residual path is proposed to cascade encoder outputs with the decoder. The experimental results demonstrate that the proposed architecture outperforms the existing deep learning techniques for eddy detection.","PeriodicalId":183947,"journal":{"name":"2022 IEEE Silchar Subsection Conference (SILCON)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123572221","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}

Identifying people based on their strides is an emerging area in computer vision. Gait recognition still confronts significant obstacles in practical applications due to the intricate outside factors that were taken into account while choosing the gait data sample and the recognized individual’s attire changes. In this work, a deep neural network ensemble model is proposed to address the the gait identification issue. In ensemble learning several deep neural networks may be trained to carry out the same task very well. To acquire deep features, we first employ two convolutional neural networks (CNNs) as feature extractors for gait energy images (GEI) and motion silhouette images (MSI). Secondly, the features recovered from the two networks are fused to boost gait identification reliability. Finally, given the fused features, we utilize the softmax classifier for final prediction. CASIA B dataset is used for the assessment of the proposed method. The study shows us that the ensemble network works well when compared with single networks and outperforms a single deep neural network, in terms of generalization.","PeriodicalId":183947,"journal":{"name":"2022 IEEE Silchar Subsection Conference (SILCON)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126211546","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, an Optical Camera Communication-based IoT Application is proposed, implemented, and evaluated. The sensed values from the temperature and humidity sensor are mapped to an 8x8 LED matrix based on the proposed frame format.

Nearly 80 percent of customer service disruptions are caused by power distribution system failures. The concept of smart distribution systems (SDS) with advanced distribution automation (DA) and communication infrastructure gives a significant potential to improve dependability by optimizing the fault identification, isolation, and service restoration process (FDISR). The use of automated safety equipment such as fault indicators, circuit breakers (CB), reclosers, remote control switches (RCS), etc. speeds up the FDISR process. A high level of reliability can be attained by using such safety devices although cost constraints limit this. The purpose of the model suggested in this paper is to site reclosers at optimal locations in a radial distribution system (RDS) for maximizing profit and creating a deregulated and competitive environment. The suggested model is validated using the mixed-integer non-linear programming (MINLP) optimization technique for the RDS connected to bus 4 of the reliability bus bar test system (RBTS). The test results support the viability and applicability of the proposed paradigm.","PeriodicalId":183947,"journal":{"name":"2022 IEEE Silchar Subsection Conference (SILCON)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130119934","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}
