    • Analysis of Strength on Thick Plate Part using Genetic Algorithm Optimisation Method 

      S., M. Azlan; Shayful Zamree, Abd Rahim; Mohd Nasir, Mat Saad; Mohd Sazli, Saad; M., M. Rashidi; Mohd Fathullah, Ghazli @ Ghazali (EDP Sciences, 2016)
      This study focuses on the optimisation of the injection moulding parameters to maximise the strength ofmoulded parts using a simulation software. The moulded parts were injected with Acrylonitrile- Butadiene-Styrene (ABS) ...
    • Application of Firefly Algorithm for Parameter Estimation of Damped Compound Pendulum 

      Mohd Sazli, Saad; Mohamad Izzat, Kamal; ‪Shayfull Zamree, Abd Rahim‬; Mohd Nasir, Mat Saad; Mohd Fathullah, Ghazli @ Ghazali (EDP Sciences, 2016)
      This paper presents an investigation into the parameter estimation of the damped compound pendulum using Firefly algorithm method. In estimating the damped compound pendulum, the system necessarily needs a good model. ...
    • Optimal process conditions of warpage with thin-shallow features molded with pin-point gating system 

      Mohd Fathullah, Ghazli@Ghazali; Shayfull Zamree, Abd Rahim; Norshah Afizi, Shuaib; Mohd Nasir, Mat Saad; Muhamad Saifuldin, Abdul Manan (Praise Worthy Prize, 2011-11)
      Thin shallow plastic parts are widely produced using injection molding processes in producing varieties of components and applications. Warpage issue always happens in manufacturing thin shallow parts due to its uneven ...
    • Optimisation of Shrinkage and Strength on Thick Plate Part Using Recycled LDPE Materials 

      Norshahira, Roslan; Shayfull Zamree, Abd Rahim; Abdellah El-hadj, Abdellah; Mohd Mustafa Al Bakri, Abdullah; Błoch, Katarzyna; Pietrusiewicz, Paweł; Nabiałek, Marcin; Szmidla, Janusz; Kwiatkowski, Dariusz; Correia Vasco, Joel Oliveira; Mohd Nasir, Mat Saad; Mohd Fathullah, Ghazali (MDPI AG, 2021-04-05)
      Achieving good quality of products from plastic injection moulding processes is very challenging, since the process comprises many affecting parameters. Common defects such as warpage are hard to avoid, and the defective ...
    • Parameter estimation of damped compound Pendulum using Bat Algorithm 

      Mohd Sazli, Saad; Luqman Nul Hakim, Mat Deri; Shayfull Zamree, Abd Rahim; Mohd Nasir, Mat Saad; Mohd Fathullah, Ghazli @ Ghazali (EDP Sciences, 2016)
      In this study, the parameter identification of the damped compound pendulum system is proposed using one of the most promising nature inspired algorithms which is Bat Algorithm (BA). The procedure used to achieve the ...
    • Warpage analysis between straight and conformal cooling channels on thin shallow shell 

      Norshah Afizi, Shuaib; Mohd Fathullah, Ghazli@Ghazali; Shayfull Zamree, Abd. Rahim; Mohd Nasir, Mat Saad; Mohd Fidzwan, Md Amin Hamzas (Trans Tech Publications, 2014)
      Warpage is a type mold defect due to non-uniform temperature variation which causes differential shrinkage rate on the moulded parts. An accurate warpage prediction is so important in helping mould designers to achieve ...
    • Warpage optimisation using Recycled Polycar-bonates (PC) on Front Panel Housing 

      Nur Aisyah Miza, Ahmad Tamizi; Abdellah El-hadj, Abdellah; Mohd Mustafa Al Bakri, Abdullah; Nabiałek, Marcin; J. Wysłocki, Jerzy; Jeż, Bartłomiej; Palutkiewicz, Paweł; Rozyanty, Abdul Rahman; Mohd Nasir, Mat Saad; Mohd Fathullah, Ghazli (MDPI AG, 2021-03-15)
      Many studies have been done using recycled waste materials to minimise environmental problems. It is a great opportunity to explore mechanical recycling and the use of recycled and virgin blend as a material to produce new ...
