Abstract
|
| |
Linear motor has gained popularity as linear motion drive in industry and factory automation. These developments were encouraged by the advantages offered by linear motors such as flexibility in size and design, and deliver high performance for applications requiring linear motion. However, the main constraint for system designer to consider linear motors in their application is the cost for every complete package of linear motor. Generally, linear motors are more expensive than its counterparts due to the sensory technologies used for positioning system... |

Abstract

Recently, the utility power quality parameters have become an important issue. One of these parameters is the presence of harmonics in the power network. The proliferation of non linear loads contributes to various orders of harmonics and serious current distortion in the electrical power system. The aim of this work is to minimize the harmonic distortion and improve the power factor of non linear loads by using digital-controlled single phase active filter. The designed single phase active filter is controlled by the digital signal processor... |

Abstract

Oil palm empty fruit bunch, an abundant agricultural waste product in Malaysia, was used to prepare activated carbon by physiochemical activation method. The pre-treated precursor was first carbonized under inert atmosphere, followed by chemical treatment using potassium hydroxide and physical activation using carbon dioxide. Scanning electron microscopy analysis showed that the activated carbon was porous with well developed pores. Adsorption isotherm of methylene blue onto the activated carbon was determined by batch tests at 300C with initial concentrations of methylene blue ranging from 50 to 500 mg/1... |

Abstract

Wire ropes are used widely in industrial applications such as elevators, lift system, cable car system and crane services. Therefore, there is an obvious need to perform tests on the integrity of these wire ropes to avoid any fatal accident due to its internal flaw. Apart from visual inspection, the non destructive test methods are available to check the condition of these wire ropes. Hall sensor and fluxgate sensor are examples of the recent methods for wire rope inspection. In this paper, a combination of two permanent magnets and a search coil are used as inductive coil... |

Abstract
|
| |
The production of crude palm oil and palm kernel is a complex problem due to the influence of some processing variables and environmental factors. The existence of some problems in the processing of crude palm oil and palm kernel, such as the properties of raw material and the lack of processing efficiencies leads to the decrease inquantity and quality of crude palm oil and palm kernel production. Nevertheless, in the production of crude palm oil and palm kernel it is essential to minimise production losses, minimise the deterioration in quality of palm oil and palm kernel during the processing and minimise production costs... |

Abstract
|
| |
The effect of OPEFB fillers on the mechanical properties and processibility of CPE-impact modified PVC-U composites were investigated. The poly (vinyl chloride) (PVC) resin, chlorinated polyethylene (CPE), oil palm empty fruit bunch (OPEFB) filler,
and other additives were first dry-blended using a laboratory blender before being sheeted with a two-roll mill. Test specimens were then hot pressed, after which the mechanical properties were determined. The processibility studies of the dry-blends were carried out using a Brabender Torque Rheometer... |

The ASEAN region has a population of more than 500 million people within its 10 member countries. Since its formation 38 years ago, significant changes and improvements have been seen, particularly in the field of science and technology. Chronologically, commencing in 1971 the Committee on Science and Technology (COST) was first established with the purpose to promote and 1ntensify cooperation in science and technological activities and to raise the level of technological and scientific advancement of member countries... |
