The parameterization of physical processes in Atmospheric General Circulation Models contribute to load imbalances among individual processors of message passing distributed multiprocessor systems. Load imbalances increase the overall time to completion of a model run and should be eliminated or reduced as much as possible. Presented is a new technique which shows promise for load-balancing the...

Cluster-Head (CH) nodes function as gateways between the sensors and the Base Station, in Wireless Sensor Networks with a cluster hierarchy. The total energy dissipation of the sensors can be reduced by optimizing the load balance within the cluster hierarchy. This paper proposes an uncapacitated facility location based cluster scheme in which the system lifetime is extended by adding an additi...

The characteristics of irregular algorithms make a parallel implementation difficult, especially for PC clusters or clusters of SMPs. These characteristics may include an unpredictable access behavior to dynamically changing data structures or strong irregular coupling of computations. Problems are an unknown load distribution and expensive irregular communication patterns for data accesses and...

Despite many nonbattle injuries reported during deployment, few studies have been conducted to evaluate the effects of deployment on musculoskeletal and physiological characteristics and balance. A total of 35 active duty U.S. Army Soldiers participated in laboratory testing before and after deployment to Afghanistan. The following measures were obtained for each Soldier: shoulder, trunk, hip, ...

BACKGROUND The authors assumed that advanced lumbar disk disease contributes to disorders of body balance and asymmetry of foot pressure force on the ground. Surgery improves biomechanical relations in the lumbar spine, thus decreasing the disturbance of postural balance and foot load. MATERIAL AND METHODS The study was carried out among 40 patients treated in Military Clinical Hospital in Wr...

There is an ever increasing need for database replication in dynamic web sites to improve availability. However, the main problem in replication is load balancing. This paper presents new load balance technique to increase the performance of database replication in dynamic web depending on the type and weight of database server queue. We attempt at evaluation various load distribution policies,...

Static standing balance was compared in 10 subjects with hemiparesis resulting from a cerebrovascular accident (33-71 years of age), 10 young normal subjects (22-40 years of age), and 10 older normal subjects (48-78 years of age) using a quantitative maximal load test and a clinical evaluation. The maximal load test required subjects to maintain a standing position against static loads applied ...

Although a large number of users are using P2P systems, the ability of these systems to provide services with quality is questioned. A load balanced P2P system can provide services with smaller failure rate and better performance; hence, service quality of the system can be improved. Cluster systems have been adopted for services which are tolerant to faults. Although a cluster structure improv...

Cluster based packet capturing is a way of overcoming the speed of a slow disk to tap a high-speed network. Most cluster-based architectures, however, do not consider load balancing as an important issue. In order to perform monitoring at full line speed without losing packets, we accept that the balance among back-end servers must be maintained. Conventional methods rely on fixed or random rou...

BACKGROUND Age-related decline in muscle power may be an early indicator of balance deficits and fall risk, even in nonfrail adults. This study examined the dose-dependent effect of power training on balance performance in healthy older adults. METHODS One hundred twelve community-dwelling healthy older adults (69 +/- 6 years) were randomized to 8-12 weeks of power training at 20% (LOW), 50% ...
