The objective of this research is to develop a turbine blade investment casting cost advisor model to assist a blade designer in decision-making in a concurrent engineering environment. It is a microcomputer based cost estimating system that employs a manufacturing knowledge base. The concept of the manufacturing process for blade production by the investment casting method is used to develop t...

the cellular therapy and nerve tissue engineering will probably become a major therapeutic strategy for promoting axonal growth through injured area in central nervous system and peripheral nervous system in the coming years. the stem cell carrier scaffolds in nerve tissue engineering resulted in strong survival of cells and suitable differentiation into neural cells, so this pathway should be ...

System Engineering, as defined in the IEEE 1220 [4], promotes a model-driven process for designing complex systems. This approach comprises three main activities: the requirement analysis, the definition of the functional architecture and the allocation to the design architecture; all of these together lead to the system architecture. The result is a system specification that defines subsystems...
