Evaluation of tunnel seismic prediction (tsp) result using the japanese highway rock mass classification system for pahang-selangor raw water transfer tunnel_W. C. Von , M. A. M. Ismail The knowing of geological profile ahead of tunnel face is significant to minimize the risk in tunnel excavation work and cost control in preventative measure. Due to mountainous area, site investigation with vertical boring is not recommended to obtain the geological profile for Pahang-Selangor Raw Water Transfer project. Hence, tunnel seismic pred... | 3/5/2020 | 1/1/2017 | Von, W. C. - Author smail, M. A. M. - Author | |
Evaluation of TBM tunnel with respect to stability agains spalling / Prof Madya Dr. Mohd Ashraf Mohd Ismail Abstract. As the depth of tunnels and underground construction increases, instability occurs in the form of rock bursting or spalling because of the induced stresses.Spall ing may appear as a strong compressi ve stress causing crack growth behind the excavated surface and buckling of the thin rock slabs. In this paper, we describe how to reduce th... | 11/12/2019 | 8/1/2019 | Prof. Madya Dr. Mohd Ashraf Mohd Ismail - Author | |
Evaluation of spalling fallout on excavation disturbed zone under deep hard rock tunnel / Romziah Azit The prediction of compressive stress-induced failures is of concern when designing and constructing facilities in rock for deep underground excavation. The purpose of this study is to model compressive stress-induced failure and fallouts with appropriate material models and strength parameters for deep hard rock tunnel excavation. Three method of n... | 3/5/2020 | 1/1/2017 | Romziah Azit - 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 | |
Environmental monitoring and controlling system for mushroom farm with online interface /Arjuna Marzuki, Soh Yan Ying Agriculture sensors play an important role in modern agriculture. The use of sensors in various agriculture sectors minimizes the environmental impact on crops, helps in increasing yield and saving cost of operation. Among all agriculture industries in Malaysia, the mushroom industry is a comparatively new and small. As most of the mushroom farms i... | 3/9/2020 | 1/1/2018 | Arjuna Marzuki - Author Soh Yan Ying - Author | |
Embolic signal identification with novel sonographic feature and fusion algorithm for automated embolization detection/Prof. Madya Dr. Dzati Athiar Ramli Stroke is the third leading cause of death for patients and commonly caused by embolus (plaque, blood clots, bubbles, etc) that travel to the brain anf lodge in the bloodstream. Many studies on strokes especially on automated detection of emboli signals have been reported: however, those studies only consider signal at certain topographic area of ... | 6/14/2019 | 6/12/2019 | Prof. Madya Dr. Dzati Athiar Ramli - Author | |
Effect ofnacl as a space holder in producing open cell A356 aluminium foam by gravity die casting process/ S.F. Aida , M.N. Hijrah, A.H.Amirah, H. Zuhailawati , A.S. Anasyida Gravity die casting is the technique which enables fabrication of open-cell A356 aluminium foam as a suitable absorber material with good quality performance. A356 aluminium alloy was used with varies amount of sodium chloride (NaCI) particles as a space holder to fabricate the aluminium foam using gravity die casting.
