Ericsson Utvecklings AB is developing a server platform, which agrees with the common telecommunication requirements. New wireless communication technologies are influencing the service and control networks’ servers. It is desirable to have reliable storage because it promises a more versatile usage of the generic server platform. Current generations of the server platform lack the support for ...

With the ever increasing applications in WWW such as distance learning education and e-commerce, the need for the reliability of the non-stop cluster web server is likely to increase. Thus, providing reliable and efficient services are the primary goals in designing a web server cluster (WSC) due to the constraints in the eventual failure of hardware/software components. In order to provide rel...

cet article est consacréà l’étude du dialogue dans enfance, récit autobiographique de nathalie sarraute qui contient des souvenirs de ses onze premières années. l’une des originalités de ce récit, se base sur la présence de deux voix narratives qui dialoguent tout au long du récit. l’une de ces dernières, joue le rôle d’une narratrice et l’autre représente le côté conscient de l’auteur qui suiv...

This paper analyzes an M/M/2 queueing system with two heterogeneous servers. Both servers goes on vacation when there is no customers waiting for service after this server 1 is always available but the other goes on vacation whenever server 2 is idle. The vacationing server however, returns to serve at a low rate as an arrival finds the other server busy. The system is analyzed in the steady st...

Hepatitis B virus (HBV) infection is a universal health problem and may result into acute, fulminant, chronic hepatitis liver cirrhosis, or hepatocellular carcinoma. Sequence for protein X of HBV was retrieved from Uniprot database. ProtParam from ExPAsy server was used to investigate the physicochemical properties of the protein. Homology modeling was carried out using Phyre2 server, and refin...

Evaluating the reliability of loosely coupled Software as a Service through the paradigm of a cluster-based and non-cluster-based web server is considered to be an important attribute for the service delivery and execution. We proposed a novel method for measuring the reliability of Software as a Service execution through load testing. The fault count of the model against the stresses of users ...

This paper studies the single server repairable queueing system with variable service rate and failure rate. The rule of variation is that changes when number customers in reaches a certain value. may fail at any time, rates idle periods busy are different. has one reliable repairman to repair server. steady-state joint distribution states obtained by matrix geometric solution method, availabil...

This paper proposes an architecture for designing fault-tolerant distributed object systems. The proposed architecture attempts to bring advances in client-server, remote procedure call, reliable group communication, and object orientation technologies under a uni ed architecture to ease application developers' work of building reliable distributed systems. The result application systems should...

Cloud computing finds applications in different industries, providing various services and data storage capabilities. While stored the cloud can be retrieved based on user requests, security remains a primary concern. To address these concerns, proposed system employs combined strength of Triple Data Encryption Standard (AES) Blowfish algorithms. The lack robust efficient secure file systems po...
