| The study of direct thermal-to-electricity conversion using thermionic heat cell device/ Assoc Prof. Dr. Khairudin Mohamed Thermionic energy conversion (TEC) is the direct conversion of heat into electricity by the mechanism of thermionic emission, the spontaneous ejection of hot electrons from a surface in vacuum environment. There are two major obstacles for achieving highly efficient TECs; the strict need for low emitter and collector work functions, and the mutual ... | 9/24/2020 | 11/1/2015 | Assoc Prof. Dr. Khairudin Mohamed - Author | |
| Finite Element Analysis of Tunnelling Induced Deformation Towards/Mohd Ashraf Mohammad Ismail, Lim Siao Phin, Tay Wui Wenn The demand of surface area increases rapidly in the urban areas due to the increase in populations. This leads to the shortage of surface area for development in the future. Underground development is one of the solutions to solve the problems, such as the tunnel constructed underground, to provide new spaces for the development without claiming va... | 3/9/2020 | 10/23/2015 | Mohd Ashraf Mohammad Ismail - Author Lim Siao Phin - Author Tay Wui Wenn - Author | |

| Evaluation of rock overstressing in the excavation of pahang-selangor raw water transfer tunnel project/Mohd Ashraf Mohamad Ismail , Romziah Azita, Norzani Mahmood Tunneling under high overburden and high in-situ stress may lead to tunnel instability due to rock overstressing in its surrounding. Overstressing of the hard rock tunnel can cause brittle fractures in the form of rock burst or spalling, which may cause safety hazards, damage of equipment and production disturbances. Therefore, the evaluation of ov... | 3/5/2020 | 10/14/2014 | Mohd Ashraf Mohamad Ismail - Author Romziah Azit - Author Norzani Mahmood - Author | |
| Pt-based catalytic microcombustor for micropower generation/Muhamad Nazri Murat Muhamad Azman Miskam, Mohd Azmier Ahmad, Zainal Alimuddin Zainal Alauddin, Mohammad Zulfikar Ishak This paper presents the fabrication and characterization of platinum-based catalytic microcombustor. The platinum catalyst was deposited onto type-304 stainless steel using the wet impregnation method. The stainless steel undergoes controlled conversion coating treatment in sulfuric acid solution to increase the porosity... | 12/10/2020 | 9/9/2014 | Muhamad Nazri Murat - Author Muhamad Azman Miskam - Author Mohd Azmier Ahmad - Author Zainal Alimuddin Zainal Alauddin - Author Mohammad Zulfikar Ishak - Author | |
| Characterization of wet impregnation method for catalytic microcombustor by using platinum/Muhamad Nazri Murat, Muhamad Azman Miskam, Mohd Azmier Ahmad, Zainal Alimuddin Zainal Alauddin, Mohammad Zulfikar Ishak The wet impregnation method for catalytic microcombustor was characterized by using platinum as a catalyst. The main purpose of this stud y i s to increase the surface porosity of the catalyst support. A high surface porosity indicates that a high amount of catalyst was deposited within the surface areas.

| Analysis of pedestrian speed flow relationship based on different egress facilities criteria for pedestrian evacuation / Nur Sabahiah Abdul Sukor The increment of the population in Kuala Lumpur had caused the LRT stations become crowded with excessive demand during the peak hours. This also includes the underground LRT stations especially near the KLCC area. Unfortunately, limited study was done regarding the pedestrian and train passengers at underground spaces in Malaysia. Due to th... | 12/30/2019 | 11/12/2013 | Nur Sabahiah Abdul Sukor - Author | |
