This Video data is stored in a video server for delivery to multiple receivers over a communications network in a traditional video-on-demand system. The hardware in this video server has the following limitations: 1) the maximum storage capacity, and 2) the maximum number of video sessions that can simultaneously be delivered. We propose a novel Adaptive-Multiple-VIdeo-Server -Architecture (AM...

One of the central and key components to make the ECommerce a success is high performance and highly reliable web server architectures. Extensive research has been sparked aiming at improving web server performance. Fundamental to the goal of improving web server performance is a solid understanding of behavior and performance of web servers. However, very little research is found on evaluating...

As video conferencing plays an increasingly critical role in many business environments, there is a need to ensure highly reliable operation of the conferencing infrastructure. We present a scheme for adding fault tolerance to an existing video conferencing server. The scheme is client-transparent so that it can be used by the installed base of clients. While the scheme is based on replication,...

Three-dimensional protein structures provide invaluable information for understanding and regulating biological functions of proteins. The GalaxyWEB server predicts protein structure from sequence by template-based modeling and refines loop or terminus regions by ab initio modeling. This web server is based on the method tested in CASP9 (9th Critical Assessment of techniques for protein Structu...

We describe the design of a system for a fast and reliable HTTP service termed Web++. Web++ achieves high reliability by dynamically replicating Web data among multiple Web servers. Web++ selects a server which is available and that is expected to provide the fastest response time. Furthermore, Web++ guarantees data delivery, provided that at least one server containing the requested data is av...

background: thioredoxin reductase 1 (txnrd1) and thioredoxin interacting protein (txnip) also known as thioredoxin binding protein 2 or vitamin d3-upregulated protein 1 are key players in oxidative stress control. thioredoxin (trx) is one of the major components of the thiol reducing system and plays multiple roles in cellular processes. computational analyses of txnrd1, txnip and trx expressio...

UNLABELLED To manage and intelligently mine the avalanche of genomic sequences intuitive and user-friendly graphical interfaces are required. Here we present BlastXtract2 which exclusively facilitates early exploration of un-annotated genomic and metagenomic sequences. Various formats of translated searches, including the commonly used BlastX, of multiple sequences against multiple protein data...

Public and private packet-switching networks (PSNs) are being developed or planned throughout the world-for example in Canada (DATAPAC), the U.S. (TELENET), France (TRANSPAC), the U.K. (EPSS), Japan (DDX), Spain, Netherlands and others. 7 Such an explosive development of data communications services is one of the means for attaining the near-perfect availability required from future distributed...

Interoperable cross-border clinical data exchange is an ambitious goal with several challenges, the most prominent ones being the structural differences in the EHR standards and the different terminologies used for semantic encodings of the data elements used in the EHRs. In this article, we address the structural interoperability problem of the EHRs by adapting the UN/CEFACT Core Component Tec...

We introduce a model for provable data possession (PDP) which allows a client that has stored data at an un-trusted server to verify that the server possesses the original data without retrieving it. In a previous work, Ateniese et al. proposed a remote data integrity checking protocol that supports data partial dynamics. In this paper, we present a new remote data possession checking protocol ...
