In todays high voltage processes the optimization of process and layout design is a key point to get competitive products. Effects like punch-through between two junctions and breakdown near the surface of the wells make it necessary to analyze complex three-dimensional process steps by simulators which give accurate answers to the process engineers.

Organizations and enterprises have developed complex data and information exchange systems that are now vital for their daily operations. Currently available systems, however, face a major challenge. On todays global information infrastructure, data semantics is more and more contextand time-dependent, and cannot be fixed once and for all at design time. Identifying emerging relationships among...

As mobility permeates todays computing environment, we envision application infrastructures that will increasingly use mobile technologies. Traditional database applications will need to integrate mobile entities: people and computers. In this paper, we develop a distributed database framework for mobile environments. A key requirement in such an environment is to support frequent connection an...

Todays, under the competitive conditions, organizational entrepreneurship can play an important role in the success of organizations and make them differentiate from others. Therefore, gaining of knowledge about the factors affecting organizational entrepreneurship is of particular importance. Accordingly, the purpose of this research was to identify and rank the factors affecting organizationa...

With todays wide acceptance of distributed computing, a rapidly growing number of application domains are emerging, leading to a growing number of ad-hoc solutions, rigid and poorly interoperable. Our response to this challenge is a platform for building flexible and interoperable execution environments (including language and system aspects) called the Virtual Virtual Machine. This paper prese...

We describe the design of PIRS, a peer-to-peer information retrieval system. Unlike some other proposed approaches, PIRS does not require the centralization of data onto specially designated peers. It is therefore applicable to a larger environment. We explain our design decisions, analyzing its benefits and potential shortcomings. We then show that PIRS significantly improves over search perfo...

Mobile ad-hoc networks (MANETs) is an appealing technology that has attracted lots of research efforts over past years. Although the principle of wireless, structure-less, dynamic networks is attractive, there are still some major flaws that prevent commercial expansion. QoS is one the main issue in todays multimedia technology. In this paper we purposed a model i.e, Priority Based Weighted Que...
