We describe how to adapt StreamLiner as a teaching tool for biology students: Streamliner provides a unified way to visualize any type of stream, including the course calendar (lectures, labs, homework, exams), external events (seminars, meetings, office hours) and work produced by the course participants (student assignments, professors' comments, blogs, wikis and group projects). We used course data from two four-month degree programs that taught biology students about computer programming. Three professors identified how key features of StreamLiner would help both students and professors and suggested additional ideas for improvement. We argue that the StreamLiner approach offers a new way of managing diverse course data and can act as a general-purpose, interactive, course-visualization tool.","PeriodicalId":375613,"journal":{"name":"2008 IEEE International Symposium on Knowledge Acquisition and Modeling Workshop","volume":"192 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134286576","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}

It was helpful for the learner to calm down, relieve the worry and enhance the study efficiency. With this, It was widely applied in all kinds of places. The Web-based course had received people's more and more favors because it provided more study opportunities, the richer the learning resources is and the more flexible learning environment. This paper first proposed the hypothesis of introducing music into Web-based course. Then the research about the feasibility of Web-based course was carried out. Finally, the concrete design and implementation of Web-based course in music environment was described in details. As a result, the proposed method could provide a comfortable learning environment for the online learner, and enable the learners to reach the best effect in study.","PeriodicalId":375613,"journal":{"name":"2008 IEEE International Symposium on Knowledge Acquisition and Modeling Workshop","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124526411","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 order to reduce the entire energy consumption of the WSN, a promising approach is to design light clustering algorithms. LEACH is such a well-known clustering algorithm that was designed to distribute the energy consumption to nodes in the WSN evenly. LEACH is characterized by its attractive cluster-based strategy; however, in the algorithm, energy dissipation of entire network is still great during the process that cluster-heads (CH) transmit data to base station (BS). In this paper, based on LEACH, we propose a modified clustering algorithm which is named ESCAL. In ESCAL, CHs won't communicate with BS directly, but transfer aggregated data to the nearest node in term of received signal strength; then this selected nearest node will compress and forward the data to BS. According to this mechanism, the transmitting distance between CHs and the base station is greatly shortened, and therefore the energy dissipation of entire network will be remarkably reduced. Theoretical analysis and experimental simulation demonstrate that the energy dissipation of ESCAL is no more than half of that of LEACH.","PeriodicalId":375613,"journal":{"name":"2008 IEEE International Symposium on Knowledge Acquisition and Modeling Workshop","volume":"260 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114466122","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 paper deals with the application of two main gas damping structure: parallel plate and perforated plate in MEMS sensors. The dynamic behavior prediction of such two damping structure based on Reynolds' govern equation has been introduced accordingly to control the dynamic performance of sensing system. The parallel damping plates are the basic structures which are able to reduce vibration and increase the quality factors of micro sensors such as accelerometers and gyroscope and so on. The gas damping effects of parallel plate can be predicted by means of conventional Reynolds' equation. The perforated damping plates are another structures which can reduce the squeeze-film effects furtherly. Although perforating holes in microstructures can reduce the damping effects caused by horizontal air flow, the air flow escaping through perforated holes adds new viscous resistance. Therefore, the conventional Reynolds' equation for determining squeeze-film damping effects of non-perforated planar structures is no longer applicable. The modified Reynolds' equation (MRE) can be employed to analyze gas damping effects of perforated plates for small amplitude vibration.","PeriodicalId":375613,"journal":{"name":"2008 IEEE International Symposium on Knowledge Acquisition and Modeling Workshop","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116151331","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}
