Simulation Of Optimal Drive Systems Consisting Of Gear-Cam Mechanisms With Brushless Dc Servomotors, Norbert Fritz

Dissertations and Theses @ UNI

This study presents the development of flexible tools for the numerical simulation of processing machine drives that consist of servomotors, mechanisms, and machine tools. The simulation allows predicting the motions or vibrations of linkages, forces and torques in joints, motor currents, and system response times as well as evaluating stability and characteristic frequencies of the drive system The simulation tools were implemented as macro components in macro component libraries using the EASY5* Dynamic System Modeling, Simulation, and Analysis software by the Boeing Company. Application of the developed macro components allows fast and efficient modeling of a variety of different drive …

A Study Of Factors Affecting The Implementation Of Iso 9000 In Taiwan's Construction Industry, Chuan-Chen Hung

Dissertations and Theses @ UNI

The purpose of this study was to determine the attitude of Taiwanese construction companies regarding the adoption and implementation of ISO 9000. This was accomplished by conducting a survey to investigate the perceived factors affecting the intention to adopt ISO 9000 and its successful implementation.

The survey instrument was developed through the review of related literature as well as through validations. One hundred eighty (180) construction companies were randomly sampled from the 1998 Membership Directory of the National Construction Association of the Republic of China (Taiwan), which consisted of 60 Type-A, Type-B, and Type-C construction companies. In total, 62 respondents …
