The Multi-Q web server provides an automated data analysis tool for multiplexed protein quantitation based on the iTRAQ labeling method. The web server is designed as a platform that can accommodate various input data formats from search engines and mass spectrometer manufacturers. Compared to the previous stand-alone version, the new web server version provides many enhanced features and flexi...

Recently, Yoon et al. proposed an efficient biometrics-based multi-server authentication with key agreement scheme for smart cards on elliptic curve cryptosystem (ECC) for multi-server communication environments [E.-J. Yoon, K.-Y. Yoo(2011) Robust biometrics-based multi-server authentication with key agreement scheme for smart cards on elliptic curve cryptosystem, Journal of Supercomputing, DOI...

Soccer, association football, is a typical team-game, and is considered as a standard problem of multi-agent system and cooperative computation. We are developing Soccer Server, a simulator of soccer, which provides a common test-bench to evaluate various multi-agent systems and cooperative algorithms. We are working on learning cooperative behavior in multi-agent environment using the server. ...

In this paper, we consider GI/M/c queues with two classes of vacation mechanisms: Station vacation and server vacation. In the first one, all the servers take vacation simultaneously whenever the system becomes empty, and they also return to the system at the same time, i.e., station vacation is group vacation for all servers. This phenomenon occurs in practice, for example, when the system con...

Queueing networks with finite buffers, multiple servers, arbitrary acyclic, series-parallel topologies, and general service time distributions are considered in this paper. An approach to optimally allocate servers to series, merge, and split topologies and their combinations is demonstrated. The methodology builds upon two-moment approximations to the service time distribution embedded in the ...

This paper deals with the joint optimization of the number of buffers and servers, an important issue since buffers and servers represent a significant amount of investment for many companies. The joint buffer and server optimization problem (BCAP) is a non-linear optimization problem with integer decision variables. The performance of the BCAP is evaluated by a combination of a two-moment appr...

Multi-server authentication is going to be an integral part of remote authentication with the passage of time. The remote authentication has been part and parcel of internet based communication. In the last decade several multi-server authentication techniques has been presented. However there is still a need of more efficient and robust techniques. Lately, Saraswathi et al., presented a multi-...

As of today, numerous researchers have explored the issue of secure and efficient smart card based authentication scheme for these variety of application areas. This article explores the background research on the single server smart card authentication schemes as well as multi-server smart card authentication schemes and its associated research gaps. This article gives comparative analysis of ...
