this paper presents a control model of the hydroforming and the dual hydroforming process of atube. the theoretical part includes calculations to measure the change in tube thickness through thedeveloped process. the hydroforming and the dual hydroforming processes are simulated in thesolidsimulation software and the static and the dynamic simulations are modeled. theobtained results for the t-...

The impact of globalization on business has forced most industries to become more innovative and implement newer strategies to retain market leadership and growth with the desired profitability. The retention of corporate engineering knowledge and rules is also critical because of the aging workforce. Knowledge based engineering is a concept that allows for the retention of corporate knowledge ...

Performance is a major issue in the acceptance of object-oriented and extended relational database systems aimed at engineering applications such as Computer-Aided Software Engineering (CASE) and Computer-Aided Design (CAD). Because traditional database system benchmarks (Bitton, DeWitt, & Turbyfill [BITT84], Anon et. al. [ANON85], TPC [TPC89]) do not measure the performance of features essenti...

One-dimensional (1-D) demonstrations, e.g., the black-box systems, have become popular in teaching materials for engineering modules due to high complexity of system’s multidimensional (e.g., 2-D and 3-D) identities. The need explanations on how multiphysics equations systems work is vital students, whose learning experience must gain a cognitive process understanding utilizing such multiphysic...

Various models have been developed, for the designing of distinct objects, for applications like font designing, Computer Aided Design (CAD), Computer Aided Engineering (CAE}, etc. Some methods are better suited for controlling the shape of the curve on an interval, while others are better suitedfor controlling the shape at the individual control points. This work reviews C2 rational splines wi...
