The problem is that such a long-term prediction of RUL suffers from the growing uncertainty in predicting the State-of-Health (SOH) of a battery as the terms or cycles of prediction increases. Conventional approaches are yet to address an effective solution to this problem. This paper presents an approach to the accurate long-term prediction of battery RUL based on the sliding window combined with sparse sampling. The proposed approach attains the accuracy by defining the window of a limited number of cycles at which SOHs are predicted single-shot and sliding the window further into the future to consecutively predict SOHs for the subsequent window of cycles. Furthermore, sparse sampling is to be incorporated into the selection of an optimal size of prediction window in such a way as to maximize the accuracy involved in a long-term prediction. A Stacked-LSTM network is adopted to carry out the prediction of a window of SOH cycles. Experiments are conducted based on the Center for Advanced Life Cycle Engineering (CALCE) dataset. The result verifies that the proposed approach tops the conventional approaches in terms of the accuracy of long-term RUL prediction.","PeriodicalId":275121,"journal":{"name":"2021 15th International Conference on Ubiquitous Information Management and Communication (IMCOM)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121128791","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}

Examples include Canada in the Americas, Singapore in Asia, and Switzerland in Europe. With the initiatives of globalization, many people immigrate or live in a country other than their birthplace. As a result, different people in the same country may have different home language (i.e., first language). For instance, as a nation composed of a highly diverse language population, Canada provides a unique opportunity to study the factors causing certain languages (or families of language) to be lost over subsequent generations among allophones (i.e., people whose mother tongue is neither English or French). In this paper, we focus on census data analytics. Specifically, we analyze census microdata by exploring machine learning and data mining techniques-such as decision tree induction, random forest, and categorical naive Bayes-to study the influence of various social and economic factors on the probability that allophones adopt official languages as their language spoken at home. This study is a showcase where natural sciences and engineering (NSE) meet social sciences, in which NSE solutions (e.g., census data analytics) are applicable for the study of social science related phenomena (e.g., successful detection of shifts in home languages).","PeriodicalId":275121,"journal":{"name":"2021 15th International Conference on Ubiquitous Information Management and Communication (IMCOM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131154362","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 online course is not necessarily a new type of course. In the universities, MOOC (Massive Open Online Course), and Moodle (learning management system), etc. have been already in service. In the school education, it is not sure that all lectures can be performed by the online course without any problems. The environmental improvement, the lecture preparation, etc. are not only barriers, but also the ages and levels of pupils, the kinds of schools, the subjects and contents of lectures, etc. are not always unified in the curriculum criterion: this fact indicates that the same procedure, the same framework and so on cannot be applicable uniformly. In this paper, we analyze the features of face-to-face course with respect to the goal and policy of school education, and then discuss the adaptability in the online course. In this case, we compare the video conference system ZOOM, the groupware system Teams with “together” mode, and our round-table-based interaction interface, and make the functionality and mechanism clear as the online course support system with interaction interface. Our round-table-based interaction interface was developed experimentally by our research project team about 12 years ago.","PeriodicalId":275121,"journal":{"name":"2021 15th International Conference on Ubiquitous Information Management and Communication (IMCOM)","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128880954","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}

For traditional stereo visual odometry (SVO), we can estimate the rotation and translation of camera motion either simultaneously or separately where 3D information reconstructed from the stereo image is used as the input of the translation estimation. The accuracy of pose estimation is dependent on the uncertainty of 3D features as well as their portion used. This paper presents a novel translation estimation for essential matrix-based SVO to avoid the effectiveness of 3D feature uncertainty from stereo disparity. The rotation is extracted accurately from essential matrix of each pair of consecutive image frames on the left side; with a pre-estimated rotation matrix, the translation is rapidly and accurately estimated by solving a proposed linear closed-form only using 2D features as input with one-point RANSAC. The experimental results on the autonomous driving testing dataset (KITTI) indicate that the proposed approach enhances 20 % accuracy compared to traditional approaches in the same experimental scenario.","PeriodicalId":275121,"journal":{"name":"2021 15th International Conference on Ubiquitous Information Management and Communication (IMCOM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125491618","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}

This fact has led to increased attacks on biometric data of users. Therefore, biometric template protection is sure to keep the attention of researchers for the security of the authentication systems. Many previous works proposed the biometric template protection schemes by transforming the original biometric data into a secure domain, or establishing a cryptographic key with the use of biometric data. The main purpose was that fulfill the all three requirements: cancelability, security, and performance as many as possible. In this paper, using random projection merged with fuzzy commitment, we will introduce a hybrid scheme of biometric template protection. We try to limit their own drawbacks and take full advantages of these techniques at the same time. In addition, an analysis of non-invertibility property will be exercised with regards to the use of random projection aiming at enhancing the security of the system while preserving the discriminability of the original biometric template.","PeriodicalId":275121,"journal":{"name":"2021 15th International Conference on Ubiquitous Information Management and Communication (IMCOM)","volume":"96 12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127994397","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}
