A new method to realize the optical perfect shuffle (PS) with a microoptical array element is presented in this paper. The whole process is simulated by computer, and parameters of the structure to fabricate the experimental component are given. The microoptical array element has been fabricated by introducing very large scale integration (VLSI), stepping(More)
Applications of advanced electronic technologies have greatly increased the efficiency and performance of safety-critical computer systems. In addition, the architectural flexibility of these systems reduces the types of printed circuit boards they can use, thereby reducing difficulties with maintenance. A newly developed safety-critical computer system is(More)
The objective of this study is to present a new numerical strategy using soft computing techniques to determine the optimal die gap programming of extrusion blow molding processes. In this study, the design objective is to target a uniform part thickness after parison inflation by manipulating the parison die gap openings over time. To model the whole(More)
This paper presents an application of an isomorphic haptic device in excavator simulation. First, we introduce system composition and techniques used in mapping position and forces. Then, the position prediction model of haptic device and the dynamic model of system are given. In addition, we describe problems and solutions in both virtual and realistic(More)
This paper discusses the necessity and main methods of developing the three-dimensional visual and interactive system. Then the method of combining OpenGL and 3DS MAX is chosen to build the system. System structure, data transmission and interaction were presented with UML. The realization of dynamic model, viewpoint control, real-time display and vanish(More)
