Recognizing and identifying the redundancy from the text documents is a challenging task that has not been fully resolved yet. In the case of multiple text document summarization processes, redundancy removal helps in getting maximum content coverage by minimizing any redundant or repetitive sentences. Another novel contribution of our work is the disambiguating a word's sense, since it helps us in getting accurate semantic similarity score between two sentences. Along with the semantic similarity score, we also consider the order of words between two sentences. Our model has the additional advantage of detecting the redundant sentences based on its meaning. Our experimental results show that the proposed WSD method outperforms many existing and current WSD methods. We have evaluated the proposed RedunWSD method on Document Understanding Conference (DUC) benchmark datasets and show that it helps in getting better recall values than many top existing query-based text summarization methods.","PeriodicalId":142284,"journal":{"name":"2021 International Symposium on Electrical, Electronics and Information Engineering","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123196070","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 present work investigates the natural low-frequency flow oscillation phenomenon of the airfoils that has the leading-edge stall type. Hybrid RANS/LES Simulations of flows around NACA0012 airfoil were conducted to obtain better understanding of this phenomenon at the angle of attack range of 13o-20o at the condition of Reynolds number 6×106 and Mach number 0.2. Results indicated that self-sustained natural low-frequency flow oscillations were taking place. Micro structures of flowfield were captured to reveal flow mechanism. A large vortex structure, formed by many small vortices, played a significant role in the phenomenon of low-frequency oscillation. A separation bubble was formed at the upper leading edge, and then the separation region expanded leading to a wide separation of the entire leeward side. The fluctuating lift coefficient showed very low-frequency unsteadiness and a large fluctuation, and the Strouhal number was about 0.01. Time-dependent flowfield showed irregular alternation between large separated flow and almost attached flow. The low-frequency oscillations were found to exist over a range of angles of attack near stall.","PeriodicalId":142284,"journal":{"name":"2021 International Symposium on Electrical, Electronics and Information Engineering","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114925883","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}
