At the same time, teachers should have a complete understanding of the participation of each student in the PBL classroom. Due to the shortage of manpower resources, a system is needed to record students' behaviors. The typical solution is to deploy a lot of prep work, either voila recognition camera installation or immobilization, which is not easy to deploy in PBL classroom. In this paper, we propose a kind of lightweight equipment, which locates in the center of the round table and is scalable to similar classroom. It can support speaker localization function, by hybrid audio-video localization algorithm. In this scheme, the basic positioning is through sound field positioning and six-microphone array, and in some difficult situations, such as people sitting close, people moving, will make the video decision method. The video is shot by a fish-eye camera for face/mouth detection and can also calculate positioning angles. Finally, the test results show that this method can effectively identify the speaker's position in class and record it.","PeriodicalId":213589,"journal":{"name":"Proceedings of the 2nd World Symposium on Software Engineering","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128318285","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}

We explore their exact influence on users' retweeting behavior, and establish a prediction model based on Naive Bayesian. Experiment indicates that the prediction model could achieve higher prediction accuracy with fewer features, which enables us to predict microblog retweeting timely in the process of dynamic public opinion propagation.","PeriodicalId":213589,"journal":{"name":"Proceedings of the 2nd World Symposium on Software Engineering","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127855836","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 addition, the traditional ARQ mechanism is inefficient and only applies to LTE systems. Therefore, an improved retransmission scheme based on wireless channel quality is proposed. The channel estimation is used to monitor the quality of the new channel in real time, and then compare the channel coefficient with the preset threshold value to adaptively select to receive feedback response. In addition, the sending and receiving scheme of the AM entity is designed in detail. The simulation result show that the ARQ mechanism proposed in this paper can achieve fast retransmission, significantly reduce the transmission delay, and increase the system throughput.","PeriodicalId":213589,"journal":{"name":"Proceedings of the 2nd World Symposium on Software Engineering","volume":"1160 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131234665","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, we propose an improving GS method for the conventional GS method based on block matrix in order to reduce complexity and accelerate the convergence rate. Simulation results show that the proposed algorithm can closely match the performance of the MMSE algorithm with few numbers of iterations.

In the applied college education, more emphasis is placed on the self-learning method of the students. The most direct way to respect students is to change the teaching methods of teachers so that students learn to learn and work in the process of receiving knowledge, so that they can be confident, act and be able to learn actively. Establish a student-centered learning model, with the cultivation of professional abilities as an important goal, change the role of teachers, return the stage of learning to students, let students do and study, and truly allow students to cultivate all aspects of comprehensive capabilities in the process. This article is based on the computer professional programming course \"programming language I\" as an example to rethink the teaching method. The difference between the new teaching method and the traditional teaching method is elaborated in detail from two aspects: classroom theory teaching and experimental practice teaching and the feasibility of the new teaching method are discussed from multiple angles. The new teaching method can fully arouse the enthusiasm of teachers 'teaching and students' learning, and realize deep learning of knowledge through experimental courses. At the same time, the new teaching methods have played a positive role in fostering students' learning initiative, teamwork spirit, language expression ability, problem analysis and problem solving skills. Under the new teaching method, the student group cultivated can better meet the current society's demand for talents.","PeriodicalId":213589,"journal":{"name":"Proceedings of the 2nd World Symposium on Software Engineering","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121796075","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}
