A synchronous communication protocol is designed and implemented for a dis tributed real time system The protocol operates on hierarchical rings and forms the communication backbone of a cluster based distributed system model that is designed to provide various distributed system functions such as clock synchronization total event ordering process group management multicasting and fault toleran...

— Many countries such as Canada, Japan, Korea and France gains their competitive advantage through the utilization of clusters development. A cluster contains many Small and Medium Enterprises (SMEs) operating in the same or similar industry strongly connected with each other to produce good and services.,In developing country , especially, Small and Medium Enterprises (SMEs) take very importan...

This paper describes a project concerned with the development of a mission planning system to provide automated planning assistance for the Air Force TechSat 21 formation-flying satellite cluster experiment: Spacecraft Cluster Automatic Planner/Scheduler (SpaceCAPS). The project’s focus is on planning and scheduling for payload management, but the system serves as a central planning system for ...

To support more efficient video database management, this paper explores the concept of video association mining, with which the association patterns are characterized by sequentially associated video shots and their cluster information. Given a continuous video sequence V, the video shot segmentation mechanism is first introduced to parse it into discrete shots. We then cluster shots into visu...

Wireless Sensor Networks (WSNs) are resource-constrained networks in which sensor nodes operate in an aggressive and uncontrolled environment and interact with sensitive data. Traffic aggregated by sensor nodes is susceptible to attacks and, due to the nature of WSNs, security mechanisms used in wired networks and other types of wireless networks are not suitable for WSNs. In this paper, we pro...

As a cost-effective alternative to large supercomputers, Beowulf clusters are now deployed worldwide to support scientific computing. While Beowulf clusters yield high computing performance, they also pose several challenges: 1) Heat induced hardware failure makes large scale commodity clusters fail quite frequently, 2) Powering all the computer nodes without adapting to the varying work load m...

BACKGROUND Health systems must transition from catering primarily to acute conditions, to meet the increasing burden of chronic disease and multimorbidity. Case management is a popular method of integrating care, seeking to accomplish this goal. However, the intervention has shown limited effectiveness. We explore whether the effects of case management vary in patients with different types of m...

This paper investigates the new problem of automatic sense induction for instance names using automatically extracted attribute sets. Several clustering strategies and data sources are described and evaluated. We also discuss the drawbacks of the evaluation metrics commonly used in similar clustering tasks. The results show improvements in most metrics with respect to the baselines, especially ...

We describe and evaluate a discriminative clustering approach for content-based tag recommendation in social bookmarking systems. Our approach uses a novel and efficient discriminative clustering method that groups posts based on the textual contents of the posts. The method also generates a ranked list of discriminating terms for each cluster. We apply the clustering method to build two cluste...

Over the last 15 to 20 years, cluster analysis has emerged as a new way of looking at economic development, integrating regional differences in development and economic specialization (Porter 1990, 2003; Sweeney and Feser 1998; Feser 2004, Cortright 2006). An increasing number of states and regions in the United States and overseas have modified their economic development strategies to focus an...
