Large-scale shared-memory multiprocessor systems are the current trend in high-performance multiprocessor systems, which are often divided into many nodes. These nodes contain a small number of processors connected by an internal bus. In this kind of system, load imbalance often occurs and can degrade the performance. This paper presents a cost-effective load balancing algorithm, which performs load...
Linear image restoration is posted as a solution to a set of ordinary differential equations (ODEs). Explicit and implicit Euler methods are used to integrate this set of ODEs. The explicit method introduces a regularization operator in the Van Cittert method, while the implicit method leads to the Tikhonov-Miller restoration. Since both methods are simply numerical integration procedures for the...
Sensor array processing algorithms for source localization often require precise knowledge of the sensor locations, which is usually not available in practice. Errors in the sensor locations have been known to degrade severely the performance of these algorithms. The authors propose an iterative Newton-type maximum likelihood array sensor location calibration algorithm using known source signals....
