This paper presents virtual machines resources scheduling algorithm taking into computing capacity of processing elements and consideration their computational complexity. We apply the improved particle swarm optimization to solve virtual machines resources scheduling problem. The experiments show that the improved algorithms can provide effective solutions that the original algorithm can not p...

Globalization spurred the rise of virtual software development teams. The complexity of managing a virtual team is rooted in the diverse cultural makeup of the team. Research increasingly recognizes that culture has significant implications for information systems. We propose in this study that the success of virtual software development team is influenced by cultural intelligence, a recent con...

Cloud computing is a new computational and commercial model. It brings the illusion of a virtually infinite computing infrastructure/platform that provides advanced features. The increased number of VMs and applications in virtualized data centers triggers serious scalability concerns with regards to monitoring. Many features of Cloud need supports from underlying Cloud monitoring system. There...

Hard Disk capacity is no longer a problem. However, increasing disk capacity has brought with it a new problem, the problem of locating files. Retrieving a document from a myriad of files and directories is no easy task. Industry solutions are being created to address this short coming. We propose to create an extendable UNIX based File System which will integrate searching as a basic function ...

The past few years have seen a rise in popularity of massively parallel architec-tures that use fat-trees as their interconnection networks. In this paper we formalize a parametric family of fat-trees, the k-ary n-trees, built with constant arity switches interconnected in a regular topology. A simple adaptive routing algorithm for k-ary n-trees sends each message to one of the nearest common a...

background : along with emersion of the internet, virtual education increasingly has been growing. many studies discussed this method and its impact on learning. present study investigated students’ attitude towards virtual education as well as its effect on learning. methods : this was a pretest-posttest quasi-experimental study. the nursing students, who had selected fluids and electrolyte di...

This article investigates the problem of designing virtual di-paths (VPs) in a directed ATM model, in which the ow of information in the two directions of a link are not identical. On top of a given physical network we construct directed VPs. Routing in the physical network is done using these VPs. Given the capacity of each physical link (the maximum number of VPs that can pass through the lin...

Today's data centres offer many different IT services mostly hosted on dedicated physical servers. Virtualization provides a technical means for server consolidation leading to increased server utilization. The term refers to the abstraction of computing resources across many aspects of computing and has been used to describe different techniques. Virtualization engines allow hosting multiple v...

The article investigates factors that may make the Nigeria Virtual Library Project a myth or reality. Questionnaires were used for data collection, using 22 University Librarians in federal universities as respondents, and 14 (64%) University Librarians completed the questionnaires. Three indicators were used to determine the myth or reality of evolving virtual libraries in Nigeria: availabilit...

The use of virtual paths in ATM networks reduces the call set-up delays, simplifies the hardware in the transit nodes and provides simple virtual circuit admission control. However, i t also reduces the degree of capacity sharing and, thus, increases the call blocking rate for most cases. In this paper, we consider the following problem: given a network topology, link capacity of each physical ...
