    Model of speed control electric wheelchair
    (2009-03-01)
    Lim, Ching Chin
    The main objective of this project was to design and develop a speed control electric wheelchair’s model. The wheelchair’s model will be used to investigate the characteristic of a speed control electric wheelchair. The project consists of building the wheelchair’s model body, designing the electronic print circuit boards (PCBs), and writing the control system coding. The body consists of a wooden strip board that holds the motor gearbox and PCB boards. The embedded electronics consists of two microcontrollers, which are connected by an I2C bus. A pair of optical encoder was used for speed or position feedback and a LCD was used for user’s display and guidance. One ultrasonic sensor added for obstacle or object sensing. The user will control the wheelchair’s model through a RF wireless remote control. The system is designed for expandability, additional I2C device can be added to the I2C bus and additional sensor can be added to the unused pins of the microcontroller. The system works as expected; we are able to control the wheelchair’s model navigation properly. Through the encoder feedback, we are able to get the running speed in RPM or the distance run in cm for both drive wheels. The encoder readings were proved to be accurate by comparison with tachometer’s readings. As a conclusion, all objectives in this project are successfully achieved.

    Industrialization And Work Values In Kedah, Penang And Great Britain: A Study From The Convergence-Divergence-Crossvergence Perspective
    (2021-08)
    Yap Chee Yeong
    The lack of discovery of the influence of industrialization on work values in Malaysian societies deters the further understanding of the reaction of Malaysians’ values to macro-level social changes. The review of prior studies shows that the influence of industrialization on work values is not consistent across societies, suggesting that it depends on the kind of society. This study aims to determine the Convergence-Divergence-Divergence (CDC) condition of work values in Malaysian societies to learn more about the influence of industrialization on Malaysians’ work values and the reaction of Malaysians’ values to macro-level social changes. In this context, work values are conceptualized into four dimensions: extrinsic work orientation, intrinsic work orientation, work centrality, and work-life balance. To test the convergence, divergence, and crossvergence hypotheses, the CDC framework was employed. 532 respondents from three regions with different extents of industrialization were involved. 175 Kedah respondents and 177 Penang respondents were recruited using convenience sampling through a face-to-face survey and an online survey, while 180 Great Britain respondents were obtained from secondary data. The responses were analyzed using the Mann-Whitney U Test and Kruskal-Wallis H Test. The results support the crossvergence hypothesis. Two out of four dimensions of work values in Penang do not differ significantly from that in Kedah and three out of four dimensions of work values in Penang do not differ significantly from that in Great Britain. This study suggests a verdict of crossvergence in work values in Malaysian societies. The extent of industrialization is influential on some dimensions of work values while some are not influenced. This implies that Malaysian societies are somewhere in the middle between adaptive and resistant when dealing with macro-level social changes.
