In many industrial situations, machines are subjected to random breakdowns. In this paper, we consider the asynchronous vacation policy for the multi-server machine repair problem with server breakdown and two types of spares. According to this policy, when a certain number of servers become idle at a service completion instant, the servers will take an asynchronous vacation of random length to...

Cloud storage allows users to store their data in a remote server to get rid of expensive local storage and management costs and then access data of interest anytime anywhere. A number of solutions have been proposed to tackle the verification of remote data integrity and retrievability in cloud storage systems. Most of existing schemes, however, do not support efficient data dynamics and/or su...

Understanding and measuring end to end service performance perceived by the clients is a chal lenging task Client perceived web site responses are downloaded web pages Typically a web page is composed from multiple objects a main HTML le and several embedded objects such as images However HTTP does not provide any means to delimit the beginning or the end of a web page to e ectively measure the...

Distributed processing systems are considered to solve the challenging requirements of trigger and data acquisition systems for future HEP experiments. The aim of this work is to present a software environment to control and monitor large scale parallel processing systems based on a distributed client-server approach developed in Java. One server task may control several processing nodes, switc...

Applying deep learning to object detection provides the capability accurately detect and classify complex objects in real world. However, currently, few mobile applications use because such technology is computation-intensive energy-consuming. This article, best of our knowledge, presents first detailed experimental study a augmented reality (AR) client's energy consumption latency executing Co...

we consider an m/g/1 queue with regular and optional phase vacation and withstate dependent arrival rate. the vacation policy is after completion of service if there are no customers in the system, the server takes vacation consisting of k -phases, each phase is generally distributed. here the first phase is compulsory where as the other phases are optional. for this model the supplementary var...

This paper presents a new and efficient method to calculate point mobilities from subcomponents of a full structure. When performing dynamic analyses of subcomponents the result normally tends to strongly depend on the boundary condition selected for the component. The goal is to simulate the results one would have received if the full model would be analysed. Normally free or clamped boundary ...
