The mechanism of glomerulotubular balance was investigated by microperfusion of the rat proximal tubule at two different rates before and after contriction of the aorta sufficient to produce a 50% reduction in whole kidney filtration rate and plasma flow. At a perfusion rate of 28 nl/min the absolute rate of proximal tubular reabsorption averaged 4.80+/-0.28 nl/mm.min in the absence of aortic c...

In parallel (IR) systems, where a large-scale collection is indexed and searched, the query response time is limited by the time of the slowest node in the system. Thus distributing the load equally across the nodes is very important issue. Mainly there are two methods for collection indexing, namely document-based and term-based indexing. In term-based partitioning, the terms of the global ind...

The radiant time series method is a new method for performing design cooling load calculations, derived from the heat balance method. It effectively replaces all other simplified (non-heat-balance) methods such as the cool#zg load temperature difference~solar cooling load~cooling load factor method (CLTD/SCL/CLF), the total equivalent temperature difference~time averaging method (TETD/TA), and ...

OBJECTIVE This study aimed to improve our understanding of static and dynamic lower extremity sensory perception and the impact of sensory impairments on the control of walking in stroke survivors. METHODS Using a custom, real-time unloading system, we tested load perception at heel strike, mid stance and push off in 10 stroke survivors and compared their performance to 10 age-matched and 5 y...

Load balance is one of the major challenges for efficient supercomputing, especially for applications that exhibit workload variations. Various dynamic load balancing and workload partitioning methods have been developed to handle this issue by migrating workload between nodes periodically during the runtime. However, on today’s top HPC systems – and even more so on future exascale systems – ru...

Low voltage microgrids including sensitive loads often face unbalanced load conditions. Therefore, a compensation procedure should be carried out in order to balance and restore sensitive load’s voltage. In this paper, an effective voltage control strategy has been proposed for the autonomous operation of microgrids, under unbalanced load conditions.  The proposed strategy balances single-phase...

More and more organizations have computing clusters located in different places. The distance between the computing clusters can be quite far away and the computing clusters can also differ in size. The load in one cluster may be very high while the other clusters may have nothing running on the system. A higher throughput can be achieved if load balancing is added. In this paper, we propose a ...

The purpose of load balancing algorithm is to distribute the excess load from heavily loaded nodes to underloaded nodes. A new dynamic load balancing algorithm is proposed based on diffusion approach (DDD) for homogeneous systems where the processing capacities of all nodes in the system are equal. The proposed algorithm works iteratively to balance the load among the nodes in a system. The dyn...

Load balancing is a critical factor in achieving optimal performance in parallel applications where tasks are created in a dynamic fashion. In many computations , such as state space search problems, tasks have priorities, and solutions to the computation may be achieved more eeciently if these priorities are adhered to in the parallel execution of the tasks. For such tasks, a load balancing sc...
