The thin-layer Navier-Stokes equations are solved for two complete missile configurations on an IBM 3090-200 vectro-facility supercomputer. The conservation form of the three-dimensional equations, written in generalized coordinates, are finite differenced and solved on a body-fitted curvilinear grid system developed in conjunction with the flowfield solver. The numerical procedure is based on ...

A new Schulz-type method to compute the Moore-Penrose inverse of a matrix is proposed. Every iteration of the method involves four matrix multiplications. It is proved that this method converge with fourth-order. A wide set of numerical comparisons shows that the average number of matrix multiplications and the average CPU time of our method are considerably less than those of other methods.

conclusions considering that the most frequent reason for our urvs was patient-related factors, where all cases had left the cpu against medical advice (ama) during their first attendance, we recommend that further appropriate strategies be devised to prevent leaving against medical advice. results patient-related factors accounted for most 72 hours urvs (49%). multivariable analysis revealed t...

CPU’s share, in overall power consumption, in a real-time system, is non-negligible. To reduce the power consumption of overall system, reduction in CPU power can be great advantage. Saving power in CPU can also advent for achieving lower operating temperature. In this writing, we show way for reducing power dissipation in CPU. The power dissipation in CPU is roughly proportional to the number ...

CPU scheduling is the basis of multi-programmed operating systems. The main objective of scheduling algorithms is to reduce the response time, waiting time and to increase the throughput and CPU utilization. Round Robin assumes that all processes are equally important; each receives an equal portion (time slice) of the CPU. This will sometimes affect the performance of CPU. This paper considers...
