    • Application of plant disease models in decision making 

      Harbant, Singh; Siti Jasmida, Jamil; Nooraihan, Abdullah; Dachyar, Arbain (Universiti Malaysia Pahang (UMP), 2009-06-20)
      Plant disease models typically are developed from field studies. The goal is to predict the risk of disease based on monitoring key environmental, host, and pathogen variables. Based on management options and goals, ...

    • Artificial neural network model for prediction of dynamical behavior in spray boom 

      Mona, Tahmasebi; Roslan, Abd Rahman; Mohammad Gohari (Universiti Malaysia Perlis (UniMAP)School of Mechatronic Engineering, 2012-02-27)
      Spray booms are usually used in farming to broadcast pesticide and chemicals. Nowadays, the widths of sprayers are increasing permanently due to increase in the width of farm yards. This issue leads to unwanted vibration ...

    • Developing a mathematical model to evaluate wear coefficient of Aluminium/Slag powder metallurgy composites 

      Zamri, Yusoff; Shamsul Baharin, Jamaludin, Prof. Dr.; Mohammed Misbahul, Amin, Prof. Madya (Universiti Malaysia Perlis (UniMAP)Institut Matematik Kejuruteraan, 2010-06-02)
      In the present work an attempt has been made to study the dry sliding wear behaviour of aluminium/slag composites fabricated via powder metallurgy. The sliding wear test has been conducted in a pin-on-disc testing ...

    • Mathematical model attitude estimation using Kalman filter technique for low earth orbit satellite 

      Nor Hazadura, Hamzah; Sazali, Yaacob, Prof. Dr.; Teoh, Vil Cherd; Siti Maryam, Harun; Hariharan, Muthusamy; Mohamad Nazri, Dol Bahar; Norhizam, Hamzah (Universiti Malaysia Perlis (UniMAP)School of Mechatronic Engineering, 2012-02-27)
      In space, the attitude analysis of a satellite is constantly being computed within the system of the satellite. In this paper, the linear mathematical model of the satellite attitude control with gravity gradient moment, ...

    • Mathematical model for in-cylinder pressure of combustion process in the diesel engine as a correlation to the external load 

      F. N., Balia; S., Mahzan; A. A., Wahab (Universiti Malaysia Perlis (UniMAP)Centre for Graduate Studies, 2010-10-16)
      In this paper, a mathematical model for in-cylinder pressure data of diesel engine is presented. Most of the researchers only developed the characteristic of the combustion process and pressure by computationally and ...

    • Mathematical modeling of human body for lifting task 

      Ku Nor Syamimi, Ku Ismail; Shafriza Nisha, Basah, Dr.; Nur Hidayah, Omar; Sazali, Yaacob, Prof. Dr.; Murugappan, Muthusamy, Dr. (IEEE Conference Publications, 2012)
      Physical lifting tasks commonly involve to types of body postures, namely, squat lifting and stoop lifting. Studies shows improper body posture during lifting task has detrimental effect to human lower-back region over ...

    • Modeling and validation of brushless DC motor 

      Mohd Sabri, Hussin; Azuwir, Mohd Nor; Nor Zaiazmin, Yahaya (Institute of Electrical and Electronics Engineers (IEEE), 2011-04-19)
      A black box modeling for a Brushless Direct Current motor is developed and simulated based on real-time data. Taking a discrete time form for the system model, an ARX model structure was selected in this work. The real-time ...

    • Modeling of structural properties of hexagonal semiconductors 

      Ghassan, E.; Arif; Farah Aini, Abdullah; Yarub, Al-Douri (Malaysian Technical Universities Network (MTUN), 2012-11-20)
      Bulk modulus of hexagonal structure semiconductors are calculated by using density functional theory (DFT) of full-potential linear augmented plane wave (FP-LAPW) within general gradient approximation (GGA). In this work, ...
