Parameter identification of three-phase induction motor using MATLAB-simulink

This paper describes a convenient method for parameter identification of induction motor. Experimental tests of induction motor, namely dc, no-load and blocked-rotor tests are conducted to identify the motor parameters. To substantiate the validity of the equivalent circuit parameters which are deduced from experimental tests, these characteristics are used to simulate virtual machines implemented under MATLAB-Simulink for modeling each tests. Finally, the result of both experimental and simulation are compared. The result shows good correlation between simulation value and values obtained from experimental tests.

Improving Safety performance through post occupancy evaluations (POE): a study of Malaysian low-cost housing

Purpose There are rising issues with the delivery performance of the Malaysian low-cost housing since the occupants are inclined to perceive safety hazards. Among the safety issues raised during the occupancy period in the low-cost housing are structural instability and falling building fragments. Without defining the occupants’ requirements in the early housing development, it is hard to determine the prevailing safety factors. Hence, this paper emphasises the application of Post Occupancy Evaluation (POE) that incorporates participation from the occupants as a tool to assess the safety performance of the Malaysian low-cost housing. The main aim of this study is to develop a framework of POE integrated with safety elements for low-cost housing (LCH) in Malaysia. Design/methodology/approach This research was conducted using a quantitative method using questionnaires as the survey instrument involving safety inspection survey and satisfaction surveys. The inspection survey and occupants’ satisfaction surve...

Propelling Site Safety Through Accident Causation Models

The function of safety is to locate and define an operational error that allows accident to occur. Previous research suggested that this function could essentially be achieved in two ways—by studying both the causes of accidents and the effectiveness of known controls being utilized. This research draws from the successful experiences of accident prevention key elements worldwide. There are many available theories on the accident accusation. The earliest models of accident causation were simple where subsequence event from the initiation of the chain to its conclusion in the accident. Lack of study was found in Malaysian environment. Thus, this research aims to create proactive measure for accident prevention in construction sites through the adaptive of accident causation theories, which signifies the identification on how hazard in construction sites causes losses. The objectives of the research are to investigate the essential elements from the available theories of the accident causation and to generate adaptive theories for accident prevention. The reviewed on accident accusation theories revealed that the shift in emphasis on the role of the management, and considered the causes of accidents are provoked among others, by actions of contractors. Thus the constraint includes the influence of management, the organisational and the environment factors that demand to be addressed to reduce the causes of an accident. The findings will contribute to the ongoing research for the development of an adaptive prevention theory for construction workplace environment. This is also directly matched to the Strategic Trust No. 3 Construction Industry Master Plan (CIMP 2006–2015), strive for the highest standard of quality, occupational safety and health and environmental practices.
