Challenge Based Learning in Students for Vocational Skills
Siti Mariam Tajuddin,Azrol Jailani
International Journal of Independent Research Studies , 2013,
Abstract: Students and vocational skills are often attributed to poor students in academic. It is less concerned about improving the quality of the students. Thus the challenge based learning is one of the efforts in producing students with vocational and soft skills as well as intelligent use of technology and facilities around them to solve real-world problems. During the implementation of challenge based learning students are given guidance in various aspects of the question of whether to be untied activities to do and the results need to be removed. At the end of teaching and learning, both sides, students and faculty members, will benefit through the sharing of information and activities.

The Social Sciences , 2013, DOI: 10.3923/sscience.2012.369.377
Abstract: This study is an attempt to explain indigenization of science in the Islamic civilization. Indigenization of science refers to the transfer process of contemporary science from a different culture to another state or nation and simultaneously redigging the old science heritage of the other nation or nations nearest to the transferee state or nation. This process as claimed by Mohamad Zain had occurred in the Islamic civilization. Hence, this study analyses the situation which had occurred in the Islamic civilization in order to confirm or refute Mohamad Zain s claim. The importance of this study is relevant as many world civilizations including the European and Japanese civilizations had achieved excellence through the indigenization of science process. The methodology used is qualitative study through instrument analysis by way of textual and contextual study of prime sources. As a result, we find that indigenization of science did indeed take place in the Islamic civilization beginning with the translation of scientific works. The Islamic civilization had also carried out re-digging of old scientific heritage from earlier civilizations. This study also shows that the Islamic civilization was able to produce original scientific works written in Arabic language. This was the pinnacle of indigenization of science in the Islamic civilization.

Journal of Engineering and Applied Sciences , 2012,
Abstract: This study presents the development of paraplegic muscle model with Adaptive Neuro-Fuzzy Inference System (ANFIS). A series of experiments using Functional Electrical Stimulation (FES) with different stimulation frequencies, pulse width and pulse duration to investigate the impact on muscle output torque are conducted. The data that is obtained is used to develop the paraplegic muscle model. The 500 training data and 300 testing data set are used in the development of muscle model. The muscle model thus developed is validated with clinical data from one paraplegic subject and in comparison with two other muscle models from previous researchers. The ANFIS muscle model is found to be the most accurate muscle model representing paraplegic muscle model. The established model is then used to predict the behaviour of the underlying system and will be used in the future for the design and evaluation of various control strategies.

Journal of Applied Sciences , 2010,
Abstract: The aim of this study was to explore and analyze the effect of different factors on the absorption of coir fiber using the developed analytical techniques employing Johnson-Allard rigid frame model. Estimated results were verified by the measurements conducted in impedance tube on normal incidence sound absorption of coir fiber. It was found that the developed analytical method can provide a well consistent agreement with the experimental results. Factors that may have positive or negative effect are elaborated in this study. It describes how the physical elements of coir fiber absorber panel can change the absorption behavior. Results obtained show that layer thickness and fiber diameter have a significant effect on the absorption, whereas bulk density does not have any considerable effect. In addition, an example is presented in order to show the approaches of enhancing the absorption utilizing the advantage of modification in the physical elements. It exhibits that properly chosen fibers along with suitable amount of bulk density can increase the absorption for the same layer thickness. It indicates that these analyses can be powerfully exploited to improve the absorption of coir fiber and at the same time maintain a reasonable thickness which would be very efficient for limited space structure. Moreover, these results can serve as a guideline for the future implementation of acoustic absorber using naturally collected coir fiber.

Abstract: This study investigate the relationships between geomorphometric properties and the minimum low flow discharge of undisturbed drainage basins in the Taman Bukit Cahaya Seri Alam Forest Reserve, Peninsular Malaysia. The drainage basins selected were third-order basins so as to facilitate a common base for sampling and performing an unbiased statistical analyses. Three levels of relationships were observed in the study. Significant relationships existed between the geomorphometric properties as shown by the correlation network analysis; secondly, individual geomorphometric properties were observed to influence minimum flow discharge; and finally, the multiple regression model set up showed that minimum flow discharge (Q min) was dependent of basin area (AU), stream length (LS), maximum relief (Hmax), average relief (HAV) and stream frequency (SF). These findings further enforced other studies of this nature that drainage basins were dynamic and functional entities whose operations were governed by complex interrelationships occurring within the basins. Changes to any of the geomorphometric properties would influence their role as basin regulators thus influencing a change in basin response. In the case of the basin's minimum low flow, a change in any of the properties considered in the regression model influenced the "time to peak" of flow. A shorter time period would mean higher discharge, which is generally considered the prerequisite to flooding. This research also conclude that the role of geomorphometric properties to control the water supply within the stream through out the year even though during the drought and less precipitations months. Drainage basins are sensitive entities and any deteriorations involve will generate reciprocals and response to the water supply as well as the habitat within the areas.

Abstract: Seat vibration is one of the major causes of discomfort in moving vehicle. Tyre, engine, drivetrain and aerodynamic forces excite the cabin and interior through various pathways. In this paper, the contributions of tyre and engine vibration to seat excitations are studied. Virtual Source Analysis (VSA) is implemented to decompose the source signals into incoherent phenomena. Studying these phenomena (virtual sources) shows the amount and frequency bands that physical sources affect the seat vibration as the response channel. Experiment is conducted while riding on smooth and bumpy roads. Road roughness is characterized using International Roughness Index (IRI). VSA technique approve that tyre is the main source of seat vibration for the moving vehicle. Seat vibration has significant values below 400 Hz and tyre is found to be the dominant source of excitations for both smooth and bumpy roads. For smooth road, strong engine harmonics below 200 Hz also has some involvements. But in bumpy road, tyre vibration rise up and become the dominant broadband source of excitations. Tyre damper and engine mount Frequency Response Function (FRF) analysis show that these parts are designed to be highly efficient below 1400 Hz and 200 Hz, respectively. These ranges are identical with those that were found as the critical operational frequency spans in VSA.

Reiza Zakia Mukhlis,Nik Abdullah Nik Mohmed,Mohd Jailani Mohd Nor
Jurnal Kejuruteraan , 2008,
Abstract: This paper discusses the performance of the suspension system that implements the flow-mode electrorheological damper in controlling the unwanted vibration caused by road surface irregularities. First, a mathematical model to determine damping coefficient of the damper was developed based on the fluid flow behaviour in the gap between two electrodes. To evaluate the performance, the system is then simulated in two kind of road excitation; abrupt excitation and harmonic excitation. The performance is characterised by the level of ride comfort and road handling. The passenger ride comfort asa evaluated by the force transmitted from the road to the passenger and by the vertical acceleration of the sprung mass, while the vehicle road haandling was evaluated by the wheel hop and the amplification ratio. The result showed that the system can obtain the best compromise between road handling and ride comfort by adjusting the electric field strength that is applied to the damper.
