The advantages of using parallel processing technology in industrial applications lie in the field of cost reduction and turnaround time improvement. For example in seismic production, the improvement in turnaround time can lead to lower costs and quicker results for clients. Also in product development where computer simulations play a significant role, for instance drug design, aircraft desig...

Queuing theory and statistical methods are used in this paper to derive formulas for determining average turnaround time in teleprocessing systems that handle messages on a priority basis. This information is needed to ensure, for example, that messages are processed within acceptable time limits and that eficient use is macle of system resources. Factors considered in arriving at the formulas ...

Magnetic random access memory (MRAM) technology, based on the use of magnetic tunnel junctions (MTJs), holds the promise of improving on the capabilities of existing charge-based memories by offering the combination of nonvolatility, speed, and density in a single technology. In this paper we review rapid-turnaround methods which have been developed or applied in new ways to characterize MRAM c...

For example, IBM, a world-known computer technology and services company, had approximately 405,000 employees in 1985. In 1992, IBM suffered $5 billion in losses. By 1994, IBM had taken a series of restructuring actions and cut its workforce to 219,207 to “streamline and reduce resource utilized in the business”. IBM began emphasizing consulting services with its 2002 purchase of Pricewaterhous...

Black holes pose a serious problem in the cyclic or oscillating cosmology. It is speculated that, in the cyclic universe with phantom turnarounds, black holes will be torn apart by the phantom energy before turnaround before they can create any problems. In this paper, using the mechanism of the phantom accretion onto black holes, we find that black holes do not disappear before the phantom tur...

We study the mean turnaround time of a Brownian needle in a narrow planar strip. When the needle is only slightly shorter than the width of the strip, the computation becomes a nonstandard narrow escape problem. We develop a boundary layer method, based on a conformal mapping of cusplike narrow straits, to obtain an explicit asymptotic approximation to the mean turnaround time. Our result sugge...
