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)
PURPOSE To apply massage therapy accompanied with stretching exercises for treatment of mammary gland hyperplasia, evaluate the clinical outcome in patients, and estimate the therapy as a novel treatment method for mammary hyperplasia. METHODS 28 adult female patients were selected and treated with massage therapy and stretching exercises focusing on(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)
