VIRTUAL prototypes, VALVES, DYNAMIC models, FLUID dynamics, TORQUE, FINITE element method, and SHANGHAI Jiao Tong University (Shanghai, China)
The article informs about a research paper by Bing Shi and Ye Jin, Shanghai Jiao Tong University at Shanghai, Peoples' Republic of China focusing on the formulation of an assembly behaviour dynamic model of reheat stop valve assembly based on virtual prototyping. The study includes fluid dynamic behaviour analysis which is implemented for the dynamic torque characteristics of reheat stop valve and for the thermal load distribution of the valve shaft-bush subassembly by finite elements method.

MULTIMEDIA systems in education, CURRICULUM planning, HIGH technology & education, and TEACHING aids
The CASCADE-MUCH system was designed to help teacher-designers in Shanghai, China with the development of instructional scenarios for multimedia curricula. After four rounds of prototyping, a summative evaluation was carried out to assess practicality. Results showed that the system was practical for the intended target users in Shanghai and also had potential for users in other contexts. The purpose of this article is to present the design process of the CASCADE-MUCH program and discuss how the evolutionary prototyping approach improved program quality and contributed to the designer’s knowledge growth.
