Knowledge-based economy forces companies in every country to group together as a cluster in order to maintain their competitiveness in the world market. The cluster development relies on two key success factors which are knowledge sharing and collaboration between the actors in the cluster. Thus, our study tries to propose a knowledge management system to support knowledge management activities...

public hospitals can privatize management activities by contracting with a private organization or person to perform the work. management contract is a method which uses private sector for major government projects like hospitals. this review study evaluated management contract conditions in selected countries. we focused on services under contract, different forms of management contract, metho...

Wireless Sensor Networks (WSN) is vulnerable to node capture attacks in which an attacker can capture one or more sensor nodes and reveal all stored security information which enables him to compromise a part of the WSN communications. Due to large number of sensor nodes and lack of information about deployment and hardware capabilities of sensor node, key management in wireless sensor networks...

Fault management in high performance cluster networks has been focused on the notion of hard faults (i.e., link or node failures). Network degradations that negatively impact performance but do not result in failures often go unnoticed. In this paper, we classify such degradations as soft faults. In addition, we identify consistent performance as an important requirement in cluster networks. Us...

Dynamic process management is a much-needed feature for applications and tools development in Beowulf cluster environment. A welldefined and efficient dynamic process management in cluster middleware layer can simplify the programming task of parallel tool developers. This paper presents the design and implementation of dynamic process management in a cluster middleware called KSIX. KSIX provid...

Cluster management middleware schedules tasks on a cluster, controls access to shared resources, provides for task submission and monitoring, and coordinates the cluster’s fault tolerance mechanisms. Thus, reliable continuous operation of the management middleware is a prerequisite to the reliable operation of the cluster. Hence, the management middleware should tolerate a wide class of faults ...

Based on the characteristics of government website construction and demands of E-government management system, this paper puts forward the methods to construct government websites by means of website cluster technology firstly. Then, it introduces innovative applications of critical techniques, employed by different subsystems, such as distributed arrangement of multiserver in the website clust...

One of the most important and typical application of wireless sensor networks (WSNs) is target tracking. Although target tracking, can provide benefits for large-scale WSNs and organize them into clusters but tracking a moving target in cluster-based WSNs suffers a boundary problem. The main goal of this paper was to introduce an efficient and novel mobility management protocol namely Target Tr...

Clustered servers for Internet service is a popular solution to cope with the explosive increase in client requests. The high probability of service failure in cluster servers make the cluster management system necessary to provide high availability and convenient administrator control. In this paper, we present the design and implementation of a load cluster management system (LCMS) based on S...

The OpenVMS Management Station software provides a robust client-server application between a PC running the Microsoft Windows operating system and several OpenVMS cluster systems. The initial version of the OpenVMS Management Station software concentrated on allowing customers to handle the system management functionality associated with user account management. To achieve these attributes, th...
