This paper constructed a web site supervision system to analyze the sentiment orientation of the articles (document, text) on the web sites in intranet. A scheme based on Vector Space Model (VSM) is put forward for identifying the sentiment orientation of document. Considering the feature of a document is relative to the term frequencies appears in the document and corpus, we extract the feature of...
This study designs and proposes a blog-based interactive patientcare system, called BiPS. BiPS provides omni-bearing patient services. It assists families, doctors and nurses to care patient's physiological information using healthcare sensors and to monitor patient's behaviors using the monitoring-based services. BiPS is a three-tier architecture that is composed of BiPS clients, the Web2.0-based...
IEEE P1900.4 is an emerging standard for optimized radio resource utilization where cognitive radio technologies are used for efficient spectrum utilization. In this paper, we design and implement a cognitive wireless network system based on open documents of IEEE P1900.4, and evaluate its performance using UDP streaming and HTTP download. Our experiments show interesting results that total network...
According to the growing of Internet, many websites have used clustering technologies to enlarge their performance. These days, LVS (Linux Virtual Server) software, which is free of charge and has good performance, has commonly been used to construct web server cluster. But when requests are increased, LVS can raise a bottleneck and can make the cluster system unable after all, because it has only...
The increasing ubiquity of mobile embedded systems has been matched by the evolution of a variety of wireless network standards and technologies. The major constraints of wireless embedded systems are limitations of communication bandwidth, processing capabilities, and battery power. Remote wireless embedded systems often act as sensors, which provide data to a certain community. The exchange of data...
