To overcome an extended relationship with a poor performing server, a client based choking algorithm was developed that enables clients to preemptively depart poor performing servers to decrease download duration. The choking algorithm employees a client based choke threshold that enables individual clients to determine when a server's performance degrades to an unacceptable level. Two separate experiments were run through a peer-to-peer simulator: single-client and multi-client scenarios. Temporal fluctuations were incorporated as well as a stochastic AR-1 random process to closely mimic expected server loads. In both instances, the choking algorithm reduces download duration.","PeriodicalId":286940,"journal":{"name":"Proceedings of the IEEE SoutheastCon 2010 (SoutheastCon)","volume":"8 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":"115272037","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}

There is a great need to manage this communication over various networks supporting different specifications. One of the widely used techniques for this type of data management is XML data interchange format. Google developers recently introduced Protocol Buffer as an alternative to XML claiming that it overcomes the shortcomings suffered by XML. This paper compares XML and Protocol Buffer data formats by extensive analysis of the two. The paper evaluates the claims made by Google by developing an algorithm to map an existing XML to Protocol Buffer format and drawing any conclusion on the efficiency and effectiveness of this format as compared to XML. It can be hoped that this work will contribute to the upcoming research in this field as people are looking for more robust data interchange format for the future of the Internet.","PeriodicalId":286940,"journal":{"name":"Proceedings of the IEEE SoutheastCon 2010 (SoutheastCon)","volume":"1 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":"130207543","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}

Many intelligence systems take advantage of streaming video and utilize high-bandwidth data links to supply information. The issue is that high-bandwidth systems typically require larger equipment, better line-of-sight, and more complex gear to keep a reliable link. The intended platform for the system described in this paper is an unmanned aerial vehicle, so the limitations of high-bandwidth equipment become more significant in a tactical scenario. By providing snapshots from the high-definition (HD) video stream, the system is able to send data to users that may not have the capability, due to a myriad of reasons, to acquire a full HD video stream. The system was developed using a Gumstix Verdex 600Mhz computer and the frame acquisition algorithm is written in C. Testing was done using HD video files streamed by VideoLan Client (VLC). The system is capable of outputting JPEG images at a maximum interval of 30 seconds. The capture system provides a method of reaching out to more users and providing functional data.","PeriodicalId":286940,"journal":{"name":"Proceedings of the IEEE SoutheastCon 2010 (SoutheastCon)","volume":"116 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":"130405628","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}

Behavior analysis of a DC distribution scheme shows that it is possible to quickly de-energize the DC bus by controlling the main converter, open a contactor to remove the faulted line, then re-energize the system. This strategy reduces the out-of-service time and avoids the use of mechanical circuit breakers and their arc-eliminating equipments. The fast response time allows unfaulted loads to ride through the process with minimal local energy storage. Our research shows that it is possible to de-energize, reconfigure, and re-energize a typical industrial DC bus 10–20 times faster than methods traditionally applied in AC circuits, and that only 470 µFarad of bus capacitance is needed for unfaulted circuits to ride-through the process uninterrupted.","PeriodicalId":286940,"journal":{"name":"Proceedings of the IEEE SoutheastCon 2010 (SoutheastCon)","volume":"25 25","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131805191","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}

Current research suggests that aspect-oriented programming (AOP) can enhance testing and has the potential to be more effective than macros or test interfaces. There are two major weaknesses when using aspects which are the inability of aspect code to be woven at all execution points and the lack of direct support for interweaving aspects with other aspects. In this paper we address the two major weaknesses and provide a means to overcome them. In addition, current research has focused only on using aspects to test functional requirements (FRs) and paid little attention to nonfunctional requirements (NFRs). In this paper we perform a feasibility study of using aspects to test NFRs which is based on two categorizations of NFRs. The first categorization splits NFRs into four types namely functionally restrictive, additive restrictive, policy restrictive, and architecturally restrictive and the second categorization splits the NFRs into two types: operational and nonoperational. These categorizations would serve as an initial point for developing frameworks or methodologies for testing NFRs with aspects.","PeriodicalId":286940,"journal":{"name":"Proceedings of the IEEE SoutheastCon 2010 (SoutheastCon)","volume":"46 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":"114279048","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}
