death is one of the main issues in samih ghasem works; because he paid special attention to it in his works. the present paper studies his ideologies about death as well as his motivations on expressing this issue. his aesthetic view strengthens resistance spirit in his hometown fellows and causes changing in their view point on death. this article has been done in descriptive – analytic method...

In a world of rapidly changing economic opportunities, institutions frequently lag relative to the objective conditions over which they apply, creating dysfunctionalities that can have high social costs. The Indian caste system is a classical example of such institutional slippage between division of labor and social class positions, with not only high welfare costs for members of lower castes ...

This opportunity for complex spatiotemporal simulation offered by digital technologies allows a subversion of the computer’s traditional role as an image production device, through its use in my own work to create preliminary sketches as a basis for sequential pieces finished in traditional analogue forms. I am currently exploring these connections via the presentation of a variety of spatial a...

From 1st to 6th June 2008, the Dagstuhl Seminar 08231 Virtual Realities was held in the International Conference and Research Center (IBFI), Schloss Dagstuhl. Virtual Reality (VR) is a multidisciplinary area of research aimed at interactive human-computer mediated simulations of arti cial environments. Typical applications include simulation, training, scienti c visualization, and entertainment...

The theme articles in this issue highlight the breadth of computer graphics and visualization research, development, and applications that make up our research eld. They range from making sense of abstract data representing physiological processes to understanding and controlling real-world tasks as executed by arti cially real creatures—robots. This spectrum of research work and their applicat...

A cognitive radio (CR) is a transceiver that is aware, adaptive, and capable of learning. It may be visualized and realized as an intelligent software package (cognitive engine) controlling a software defined radio platform. The cognitive engine executes a set of nested loops constituting a cognition cycle, drawing on experience and stored knowledge to optimize a set of user-chosen quality of s...

Interactive graphics, and especially virtual reality systems, require synchronization of sight, sound, and user motion if they are to be convincing and natural. We present a solution to the synchronization problem that is based on optimal estimation methods.
