    • Design and development of tracking system for mines detector robot 

      Ahmad Firdaus, Ahamad Zaidi; Ng Shao, Liang; Mohd Hafis, Sulaiman; Mohd Ridzuan, Mohd Jamir; Nur Hidayah, Ahmad Zaidi (Trans Tech Publications, 2014-01)
      This paper presents the design and development of tracking system for the mines detector robot. The scope for the tracking system covers two important tasks: 1. Design of optimum tracking path to cover maximum scanning ...
    • Identification of limiting friction coefficient towards improved hip prostheses 

      Mohd Hafis, Sulaiman; Nur Farahana, Ramli; Mohd Ridzuan, Mohd Jamir; Siti Mahani, Said (Trans Tech Publications, 2013)
      Wear generated by the presence of friction on hip joint contact surfaces can cause debris, which may lead to loosening and failure of the hip prostheses. The objective of this study is to examine the limiting friction ...
    • Optimal coefficient of friction onartificial knee joint contact surfaces 

      Mohd Hafis, Sulaiman; Nur Farahana, Ramli; Mohd Ridzuan, Mohd Jamir; Nur Adlina, Mohd Takhiudin (Trans Tech Publications, 2013)
      Wear generated by the presence of frictiononknee joint contact surfaces can cause debris, which may lead to failure of the artificial knee joint. In this study, the effects of friction coefficients occur on the knee joint ...
    • Paraffinic mineral oil lubrication for cold forward extrusion: Effect of lubricant quantity and friction 

      Mohd Hafis, Sulaiman; Mohd Ridzuan, Mohd Jamir; Nur Farahana, Ramli; Syahrullail, Samion (Elsevier Ltd., 2013)
      In this paper, Finite Element (FE) and experimental analyses have been developed on the deformation of aluminium billet over a tool. Effect of friction resulted from the use of additive-free ISO460-compliant paraffinic ...
    • Performance of thermoelectric cooling system: effect of aluminium heat sink and heat dissipation 

      Mohd Hafis, Sulaiman; Mohd Ridzuan, Mohd Jamir; Ahmad Firdaus, Ahmad Zaidi; Mohammad Shahril, Salim; Nur Farahana, Ramli; Cheong, Chee Kin (Trans Tech Publications, 2014)
      This paper presents theoretical and experimental research works on the effect of aluminium heat sink and heat dissipation in a portable thermoelectric (TE) cooling system. In this study, three units of TE modules were ...
