An implementation of a particle system as part of the rendering pipeline of a 3-D computer game is described. Due to the interactive nature of such a computer game one of the most important issues in this implementation is the real-time rendering capability of the created special effects. A short summary of the game’s rendering pipeline is given, restrictions on special effects without a partic...

Communication media have become the primary way of interaction thanks to the discovery and innovation of many new technologies. One of the most widely used communication systems today is video streaming, which is constantly evolving. Such communications are a good alternative to face-to-face meetings, and are therefore very useful for coping with many problems caused by distance. However, they ...

One of the most important issues in web mining is how to find out similarities between web pages. In this paper we propose a method based on distributed learning automata which take advantage of usage data to find out web pages similarities. The idea of the proposed method is that if different users request a couple of pages consistently together, then these pages are likely to correspond to th...

god-centered theories about the meaning of life maintain that a certain relationship with god is an essential condition for life to be meaningful. different interpretations have been proposed in regard to this theory, but the most important god-centered interpretation is the divine purpose theory. according to this theory, fulfilling god’s purpose is the only source of the meaningfulness of lif...

My research involves developing models and tools to support architecture-level planning of large software evolutions. Over the past couple of years, we have developed a theoretical framework that we think encapsulates the most important issues in these kinds of evolutions, as well as formal models and tool prototypes within this framework. One important component of our framework involves the f...

One of the most important issues in the management of disasters that caused by natural phenomena in urban areas is how to evacuate inhabitants of hazardous areas to safe areas. Optimal allocation of capacities in safe areas to inhabitants leads to effective decision making by inhabitants for displacement to safe areas in evacuation process. Effective decision making in disaster management is so...
