during the recent decades, substantial changes are made in the borders and contents of physiology as a basic course for the students in medicine. here some strategies are presented to preserve the classical and integrative approaches in teaching physiology, while these approaches extent our knowledge to molecular, sub-cellular and cellular levels.

Recently, major services provided by mobile communications systems are shifting from voice conversations to data communications over the Internet. There is a strong demand for increasing the data transmission rate. However, an important problem arises; larger peak transmit power is required as transmission rate becomes higher. In this paper, we propose a wireless multi-hop virtual cellular conc...

In past decade, new approaches to cell formation for cellular manufacturing systems was developed and applied. To be specific, Genetic Algorithm, Simulated Annealing, Ants colony systems, Particle Swarm Optimization, and Tabu search etc... are in this paradigm. When the implementation stage knocks the door, there is a great deal whether it can be applied in reality or not. Keeping this in mind,...

The present manufacturing sectors are burdened with increasing speed of transitioning new global business developments into production processes. This forces the old approaches of information management to adopt better evolution capabilities. Although the concept of virtual manufacturing is to facilitate integration of production processes in global industrial organizations, its information man...

The research area “Virtual Manufacturing” can be defined as an integrated manufacturing environment which can enhance one or several levels of decision and control in manufacturing process. Several domains can be addressed: Product and Process Design, Process and Production Planning, Machine Tool, Robot and Manufacturing System. As automation technologies such as CAD/CAM have substantially shor...

— Cellular Manufacturing (CM) system has been recognized as an efficient and effective way to improve productivity in a factory. In recent years, there have been continuous research efforts to study different facet of CM system. The literature does not contain much published research on CM design which includes all design aspects. In this paper we provide a framework for the complete CM system ...

This paper deals with the transient analysis of manufacturing systems in the presence of failures and repairs. The exact model is decomposed into 1) a structure state process, modeling the failure and repair events which occur at a slower time scale, and 2) a performance model, modeling the part processing and material movement events occurring at a faster time scale. The solutions of these two...

In the manufacturing industry, they are using various concepts and solutions in order to reduce time and costs in the product development. This article introduces an approach that enables Virtual Engineering and links engineering applications with Virtual Reality (VR) solutions. Thus an environment is provided to implement virtual design reviews and enable the application of virtual prototyping...

Virtual reality (VR) has become an important and useful tool in science and engineering. VR applications cover a wide range of industrial areas from product design to analysis, from product prototyping to manufacturing. The design and manufacturing of a product can be viewed, evaluated and improved in a virtual environment before its prototype is made, which is an enormous cost saving. Virtual ...
