摘要：本文对各种磁流变阻尼器的优化设计、制造和智能应用以及自供电和自感应技术的最新进展进行了综述。本文讨论了磁流变阻尼器的基本设计和结构以及各种类型的配置,以了解它们在各种环境和目的下的多功能性。为了应对不同的应用,本文介绍了设计的修改、优化和改进。节能是当前的终极需求,是对现代技术的挑战。磁流变阻尼器需要改进,以确保较低的电流供应得到较高的效力。这项工作将有助于在各种结构中使用磁流变阻尼器,使其以最小的电流供应进行振动控制,并在优化中获得最佳结果。

摘要：In the present study to produce a typical hip joint, Investment casting has been selected as casting method since this process can give optimum properties of the product having complex geometry with biocompatible material. In order to perform this casting, a die or mould is needed to fabricate wax pattern, which will be used to make ceramic investment for the hip joint. Thus, this study includes the modification of design together with fabrication of a typical hip joint casting dies with acrylic. Throughout the project, modulus of casting and riser has been calculated and accommodated with the main hip joint die design. The hip-bone joint design has been generated using CATIA V5 software before it is converted into numerical control (NC) codes to machine the two acrylic slabs of the acrylic dies using Vertical Machining Center (VMC). Thus, the acrylic dies for hip bone joint are now ready for making wax pattern intended to produce ceramic investment for casting the required joint with biocompatible material.

摘要：malaysia is a multicultural, multireligious, and multiethnic country that is located in Southeast Asia. The social background of malaysia as a multicultural state calls for the adoption of an alternative method to resolve community dispute which would offer solution and simultaneously promote harmonization in the society. Community mediation may be one of such alternative, if not the best method for interethnic relations. The government of malaysia has introduced community mediation in malaysia by providing training for community mediators through a pilot program, known as Rukun Tetangga (Peaceful Neighbor). The purpose of this program is to promote unity among the multi-races and multiethnic citizens. This paper will refer to the current practice of community mediation in malaysia as provided by the National Unity Department in Peninsula malaysia and the practice of community mediation in Singapore. It is hoped that by comparing the practices in both countries, suggestions and recommendations could be made to improve the practice of community mediation in malaysia.
