Traditional architectures can sometimes have trouble meeting these expectations, so more fault-tolerant architectures are needed to fulfil these needs. This article introduces the concept of computer clustering for a Web application environment. It describes the advantages of computer clustering, different types of clusters and common configurations for computer clusters which ensure reliability, improved performance and scalability for business applications. Steps are provided for the configuration of a computer cluster for Web applications using BEA Systems' Weblogic Server 8.1 and Sun's Java Systems Web Server 6.1.","PeriodicalId":423683,"journal":{"name":"Proceedings 2007 IEEE SoutheastCon","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124206134","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}

Field electron emission from carbon nanosheets was measured under diode mode. Carbon nanosheets samples have turn-on fields of 5-10 V/mum, and can yield a total emission current of 28 mA from an area of 8 times 8 mm2 and an emission current density of ~2 mA/mm2 from an area of 1 times 1 mm2.

This allows health care professionals to gain access to patient information from anywhere at anytime. In this project, the wireless patient management system was built using Java technology. The client side was implemented using MIDlet and the server side was developed using Java servlets. A study was conducted to observe the effects of distance between client and server on the response time of a wireless versus wired connectivity. It was observed that the distance between the client and server does not have a significant impact on the response time of wired and wireless connectivity.","PeriodicalId":423683,"journal":{"name":"Proceedings 2007 IEEE SoutheastCon","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123480975","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 focuses on the enhancement of speaker recognition through fusion of likelihood scores generated by arithmetic harmonic sphericity (AHS) and hidden Markov model (HMM) techniques. Due to the contrastive nature of AHS and HMM, we have observed a significant performance improvement of 22% and 6% true acceptance rate at 5% false acceptance rate, when this fusion technique was evaluated on two different datasets - YOHO and USF multimodal biometric dataset, respectively. Performance enhancement has been achieved on both the datasets, however performance on YOHO was comparatively higher than that on USF dataset, owing to the fact that USF dataset is a noisy outdoor dataset whereas YOHO is an indoor dataset.","PeriodicalId":423683,"journal":{"name":"Proceedings 2007 IEEE SoutheastCon","volume":"215 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123393467","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}

Often medical images of high resolution are stored on computers and therefore require a large amount of disk space. In recent years, there have been extensive interest and research in the development of effective and efficient methods of extracting patterns and features from medical images. Knowledge discovery tools can be used to efficiently analyze large data, but often a data reduction technique is required to obtain a manageable size data. In this research we used wavelet lifting schemes for data reduction and several shape histogram-inspired data sectorization techniques for knowledge discovery and analyses.","PeriodicalId":423683,"journal":{"name":"Proceedings 2007 IEEE SoutheastCon","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116686217","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}
