The power source has been designed to ride through a 2s voltage sag caused either by high load demand or remote system fault. The simulation model currently supports study of both power injection and power absorption. Response of the SC storage to a line fault has also been studied and compared with the response due to high load demand. Simulation results verified the effectiveness of the integrated system and forms the basis for further development of a more robust system in terms of power management.","PeriodicalId":286940,"journal":{"name":"Proceedings of the IEEE SoutheastCon 2010 (SoutheastCon)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124403068","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}

To address this problem, in this paper, a project-centered pedagogy is proposed and its practice reported. The central idea of the proposed strategy is to develop a series of projects each focusing a particular issue or topic in the subject, then, after outlining the basic principles, it is up to the students to find out all the necessary details and weave all their acquired information and know-how into easily presentable outcomes to meet the requirements of each project. Upon completing the series of projects, students become adept in finding required information and conducting necessary research to produce desired project outcomes. In the mean time, students are better trained to adapt to the ever changing technologies and industry practices, and be better prepared to face the real world upon graduation.","PeriodicalId":286940,"journal":{"name":"Proceedings of the IEEE SoutheastCon 2010 (SoutheastCon)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121932433","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 proposes a closed-loop control strategy of the braking resistor based on thyristor technology to stabilize the wind generator system. The performance of the proposed braking resistor is evaluated in detail considering both balanced and unbalanced types of temporary and permanent faults in the system. A comparison is made between the performance of the proposed braking resistor and that of the conventional braking resistor employing a fixed insertion period. Simulation results show that the proposed braking resistor is very effective to stabilize the wind generator system in case of both balanced and unbalanced types of transient and permanent faults. Also, the performance of the proposed braking resistor method is much better than that of the conventional method.","PeriodicalId":286940,"journal":{"name":"Proceedings of the IEEE SoutheastCon 2010 (SoutheastCon)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125031314","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}

Traditionally, the approach from the a video server has been to send the contents of the entire video stream as quickly as possible, which we shall refer to in this paper as “rapid” downloading. Rapid downloading does not field optimal bandwidth usage for sending variable bit rate (VBR) HD videos, and may result in a high number of packet losses over the Internet when peak rates are demanded by the video stream. We propose a solution that focuses on “progressive” downloading where the stream is sent in progressive blocks. With VBR videos, particularly 1080p HD videos encoded using H.264, this approach provides better buffer and bandwidth utilization. We will also show that with video smoothing and compound TCP, further performance gains can be achieved.","PeriodicalId":286940,"journal":{"name":"Proceedings of the IEEE SoutheastCon 2010 (SoutheastCon)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130810490","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}

Most of these networks support only nomadic mobility of wireless devices. However, in case of vehicle-to-infrastructure communications the mobile devices in the vehicles need to have the ability to quickly switch their association to a new access point (AP) when they move out of range of their initial access point to ensure seamless connectivity. The handoff latency in vehicular environments can be improved if the mobile device has prior knowledge about the channels that access points in its vicinity are using. This paper describes a testbed for testing vehicle-to-infrastructure communications and gives experimental results showing improvement in handoff latency with prior knowledge of channels to scan.","PeriodicalId":286940,"journal":{"name":"Proceedings of the IEEE SoutheastCon 2010 (SoutheastCon)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121722420","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}
