Aerodynamic changes when two Vehicles are in a Proximity to each other

Aerodynamic of the fluid surrounding two vehicle changes when the vehicles are in proximity to each other, whether when overtaking, or moving back-to-back, or sideby- side from the same or opposite direction. Usually when the cars are moving near each other, aerodynamic changes, especially the wake that forms around the vehicle can create force variation on the vehicle, causing sometimes road accidents. For the Final Year Project (FYP), the aerodynamic changes will be studied on model vehicle using a wind tunnel equipped with the necessary measuring equipment. The study is focusing on the effects of the wake of a vehicle to another vehicle in tailing position (back-to-back), where the experiment is done using windtunnel and scaled vehicle models. The vehicle model used is a scaled model of a kelisa car. The results of the experiment show that there are certain ranges of distance between the two cars, where the drag force, as a result of the aerodynamic changes, increase and decrease. These distance ranges are where a driver should or should not be when tailing another vehicle on the road

Pengaruh Kepimpinan Pengajaran Guru Besar, Kompetensi Profesionalisme Guru dan Kompetensi Peribadi Guru Terhadap Efikasi Pengajaran Guru Sekolah Rendah di Zon Pedalaman Sabah

Kajian ini bertujuan untuk menentukan kekuatan pengaruh kepimpinan pengajaran guru besar, kompetensi profesionalisme guru dan kompetensi peribadi guru terhadap efikasi pengajaran guru bagi guru-guru sekolah rendah di zon Pedalaman, Sabah. Kajian ini melibatkan 361 responden yang terdiri daripada guru-guru sekolah rendah di zon Pedalaman, Sabah. Pemboleh ubah kajian telah diuji dengan menggunakan statistik deskriptif dan inferensi yang melibatkan skor min, sisihan piawai dan regresi berganda. Instrumen yang digunakan dalam kajian adalah soal selidik yang diadaptasi daripada Principal Instructional Management Rating Scale (PIMRS), Standard Guru Malaysia (SGM) dan Teacher Efficacy Scale (TES) bagi mengumpul data daripada 361 responden yang telah melengkapkan borang soal selidik, daripada 54 buah sekolah rendah yang melibatkan tujuh daerah di zon Pedalaman, Sabah. Persampelan secara rawak digunakan dalam pemilihan responden dalam kalangan guru manakala persampelan bertujuan digunakan bagi menentukan bilangan sekolah yang mewakili setiap daerah seperti yang telah ditetapkan. Statistik deskriptif dan inferensi telah digunakan bagi menghuraikan dapatan kajian. Dapatan kajian menunjukkan bahawa tahap kepimpinan pengajaran guru besar (Min = 4.52; SP = 0.313) pada tahap sangat tinggi, kompetensi profesionalisme guru (Min = 4.41; SP = 0.295) juga pada tahap sangat tinggi dan kompetensi peribadi guru (Min = 4.47; SP = 0.366) juga berada pada tahap sangat tinggi manakala efikasi pengajaran guru (Min = 3.96; SP = 0.358) berada pada tahap tinggi. Data inferensi dianalisis menggunakan regresi berganda. Analisis regrasi menunjukkan pengaruh kepimpinan pengajaran guru besar menyumbang 65 peratus, kompetensi profesionalisme guru menyumbang 65.9 peratus dan kompetensi peribadi guru menyumbang 66.5 peratus terhadap efikasi pengajaran guru dan merupakan peramal yang signifikan kepada tahap efikasi pengajaran guru

Segmentation of Brain Magnetic Resonance Images (MRIs): A Review

Abstract MR imaging modality has assumed an important position in studying the characteristics of soft tissues. Generally, images acquired by using this modality are found to be affected by noise, partial volume effect (PVE) and intensity nonuniformity (INU). The presence of these factors degrades the quality of the image. As a result of which, it becomes hard to precisely distinguish between different neighboring regions constituting an image. To address this problem, various methods have been proposed. To study the nature of various proposed state-of-the-art medical image segmentation methods, a review was carried out. This paper presents a brief summary of this review and attempts to analyze the strength and weaknesses of the proposed methods. The review concludes that unfortunately, none of the proposed methods has been able to independently address the problem of precise segmentation in its entirety. The paper strongly favors the use of some module for restoring pixel intensity value along with a segmentation method to produce efficient results

Classification of Potential Risk Factors through HIRARC Method in Assessing Indoor Environment of Museums

Museums were established in Malaysia more than a hundred years ago. Since the year 2005, Malaysian government has discouraged constructing new purposely built museums in favour of refurbishing historic and old buildings to function as adaptive reused museums. Commonly due to insufficient ventilation, fully mechanically ventilated museums can pose critical indoor environmental issues that may lead to health hazards and risks among employees and visitors. Thus, the purpose of this study is to determine the potential risk factors within the museums based on indoor environmental criteria. This potential risk factors are resulted from the ‘Potential Risk Categories’, which have been developed by adopting the established Hazard Identification, Risks Assessment and Risk Control (HIRARC) Method. Based on the assessment of four main indoor environmental criteria in the Potential Risk Categories, it was discovered that 8 out of 24 museums are in the range of medium potential risk, while the rest of them are in the range of low potential risk. The ‘Potential Risk Categories’ is important for assessing indoor environment at the museums whereby the most critical risk could be assessed, and then suggestion could be provided to minimize the potential risk within the spaces inside the museums
