Use of Internet and frequent accesses of large amount of multimedia data are fast increasing the traffic of network. Performance evaluation and high availability of server are important factor to resolve this problem using various cluster based systems. There are several low-cost servers using the load sharing cluster system which are connected to high speed network, and apply load balancing te...

In many cases, a simulation model of a system is used to evaluate alternative configurations of that system, with the goal of finding the configuration which maximizes (or minimizes) the value of an objective while meeting all of the stated requirements. The CSIM18/OptQuest package automates this kind of search for the best configuration by combining a powerful simulation engine, CSIM18, and a ...

The NASA Technical Report Server (NTRS), a World Wide Web report distribution NASA technical publications service, is modified for performance enhancement, greater protocol support, and human interface optimization. Results include: Parallel database queries, significantly decreasing user access times by an average factor of 2.3; access from clients behind firewalls and/ or proxies which trunca...

Load balancing of the Internet bank can be implemented by reduction of the workload of the bottleneck Web server. Load balancing improves both a performance of the computer system and the reliability of a server network. An evolutionary algorithm improved by introducing a tabu search procedure is discussed for solving multi-criteria optimization problem of finding a set of Pareto-suboptimal tas...

The evolution of the Web as an enabling tool for e-business introduces a challenge to understanding the execution behavior of largescale middleware systems, such as J2EE [2], and their commercial workloads. This paper presents a brief description of the whole-stack analysis and optimization system – being developed at IBM Research – for commercial workloads on Websphere Application Server (WAS)...

Structural details of protein-protein interactions are invaluable for understanding and deciphering biological mechanisms. Computational docking methods aim to predict the structure of a protein-protein complex given the structures of its single components. Protein flexibility and the absence of robust scoring functions pose a great challenge in the docking field. Due to these difficulties most...

Recently, the Internet has been expanding intensively; the number of WWW (World Wide Web) users has been growing, and the network capacity provided by network carriers and Internet service providers has been increasing for enabling high quality services. The Internet users would pay the reasonable cost for a reasonably better service. For ISP (Internet Service Provider) to provide better QoS (Q...

The main object of this research is to optimize an end-filled castellated beam. In order to support high shear forces close to the connections, sometimes it becomes necessary to fill certain holes in web opening beam. This is done by inserting steel plates and welding from both sides. Optimization of these beams is carried out using three meta-heuristic methods involves CSS, CBO, and CBO-PSO al...
