Multiple sequence alignments are often used for the identification of key specificity-determining residues within protein families. We present a web server implementation of the Sequence Harmony (SH) method previously introduced. SH accurately detects subfamily specific positions from a multiple alignment by scoring compositional differences between subfamilies, without imposing conservation. T...

Web usage mining is an application of data mining technology to mine the data of the web server log file. It can discover the browsing patterns of user and some kind of correlations between the web pages. Web usage mining provides the support for the web site design, providing personalization server and other business making decision, etc. Web mining applies the data mining, the artificial inte...

Web Accelerators are increasingly becoming an integral part of the Web site content delivery infrastructure. As such, Web accelerators must address some common server issues such as: capacity, performance, and availability. A set of Oracle9iAS Web Cache instances can be grouped into a loosely coupled cluster to help solve these issues. When clustered, the cache capacity increases linearly. In a...

This paper surveys distributed computing techniques used in the implementation of BEA WebLogic Server. It discusses how application servers provide a distributed transactional infrastructure that extends outward from backend databases. The basic treatment of data is characterized in terms of four types of clustered services that differ in the way they manage state in memory and on disk. This pa...

Most high-availability (HA) solutions currently used are based on the pre-configuration done by human administrators. If the configuration between machines participating in the HA cluster can be automated, services clustered can be provided more efficiently. For realizing this concept, the server agent and service description server (SDS) are designed and implemented in this paper. The server a...

SUMMARY We present a web server that computes alignments of protein secondary structures. The server supports both performing pairwise alignments and searching a secondary structure against a library of domain folds. It can calculate global and local secondary structure element alignments. A combination of local and global alignment steps can be used to search for domains inside the query seque...
