This paper studies a loss and delay queueing model under the restriction of N-policy for the situations where arrival and service of customers are correlated and follows a bivariate Poisson process. When there is no customer present in the system then the server goes on vacation and returns back in the system whenever the specified N (>1) or more customers are accumulated. The server may breakd...

Multipactor breakdown analysis is presented in cylindrical dielectric resonator waveguide filter under its dual-mode behavior. The method of effective electron algorithm with combination of Monte-Carlo method is used to perform the simulation and predict multipactor breakdown thresholds. The breakdown thresholds of the proposed structure are presented for different values of frequency-gap produ...

In this paper considers M[X1]/G1/1, M[X2]/G2/1 , M[X3]/G3/1 general queueing system with priority services . Three types of customers from different classes arrive at the in independent Poisson process. The server follows non preemptive rule subject to working breakdown, and modified Bernoulli vacation (arbitrary) periods. After completing service, if there is no high present system. time depen...

In many industries and plants, a stable power supply system with acceptable cost/benefit is essential. This paper investigates the cost-effectiveness of an unreliable retrial that includes standby generators experiences switchover failures generators. Four different configurations are included, each configuration various numbers primary Upon arrival, failed generator repaired immediately if ser...

In this paper, we present a novel algorithm for VANET using cloud computing. We accomplish processing, routing and traffic control in a centralized and parallel way by adding one or more server to the network. Each car or node is considered a Client, in such a manner that routing, traffic control, getting information from client and data processing and storing are performed by one or more serve...

The ETICA project aims to identify emerging information and communication technologies. These technologies are then analysed and evaluated from an ethical perspective. The aim of this analysis is to suggest possible governance arrangements that will allow paying proactive attention to such ethical issues. During the ETICA workshop at the summer school, participants were asked to choose one of t...

This paper presents a unique flywheel-based regenerative energy recovery, storage and release system developed at the author’s laboratory. It can recover and store regenerative energy produced by braking a motion generator with intermittent rotary velocity such as the rotor of a wind turbogenerator subject to intermittent intake wind and the axels of electric and hybrid gas-electric vehicles du...

The SUPERFAMILY database contains a library of hidden Markov models representing all proteins of known structure. The database is based on the SCOP 'superfamily' level of protein domain classification which groups together the most distantly related proteins which have a common evolutionary ancestor. There is a public server at http://supfam.org which provides three services: sequence searching...

Two-phase M/Ek/1 queueing system with N -policy for exhaustive batch service with gating, and server startups and breakdowns is studied in this paper. The customers arrive individually according to a Poisson process and waiting customers receive batch service all at a time in the first phase and are served individually in the second phase. The server is turned off each time the system empties, ...

The author considers a batch arrival queueing system in which two types of customers (namely positive and negative) arrive. The arrival of a negative customer to a queueing system removes one positive customer who is in service if any. A cycle starts whenever the system empties and the server is turned off and stays idle in the system. The idle period ends as soon as a batch of positive custome...
