because of heavy competition between auto manufacturer and the threats of foreign companies, they try to reduce the internal competition and costs by cooperation and merge. estimation about the auto market is affected by supply and demand. the demand depends on two factors: need for new cars and old cars exit. and the supply depends on production capacity and export. key factors that affected o...

In this paper, we describe the design of a profile generator toolkit, which aims to automatically create realistic user profiles for a mobile personalized portal service. These profiles simulate actual user behavior and are utilized to experiment with a personalized crawling system, called eRACE. With the help of this tool, we will assess the performance and scalability of the eRACE system by c...

The article focuses on one genre of simulations: computer and video games. The author presents a generic model of the elements that co-operate in producing a simulation that is also a game. The model is applied into practice with a case study that focuses on one particularly interesting game: Grand Theft Auto: Vice City (Rockstar Games, 2002), a game that frames its gameplay by simulating certa...

A common problem in networking research and development is the duplicate effort of writing simulation and implementation code. This duplication can be avoided through the use of fast-prototyping methodologies, which enable reusing simulation code in real prototyping and in production environments. Although this functionality is already available by using ns-3 emulation, there are still limitati...
