    • Design and modelling of ultrasonic tomography for two-component high-acoustic impedance mixture 

      Mohd Hafiz, Fazalul Rahiman; Ruzairi, Abdul Rahim; Zulkarnay, Zakaria (Elsevier B.V., 2008-10)
      This paper describes the design and modelling of ultrasonic tomography for two-component high-acoustic impedance mixture such as liquid/gas and oil/gas flow which commonly found in chemical columns and industrial pipelines. ...

    • Diagnostics of Oil Filled Cable Terminations 

      Mohd Rafi, Adzman; Muzamir, Isa; Baharuddin, Ismail; Lehtonen, Matti; Hyvonen, Petri (Kolej Universiti Kejuruteraan Utara Malaysia, 2006)
      Cable termination is one of the important components in the electrical power system. A failure of it can cause a long interruption, costly repair and loss of revenue. An existing oil filled cable termination such as rubber ...

    • Embedded smart camera performance analysis 

      Kahar, N.F; R.Badlishah, Ahmad; Zulkifli, Hussin; Ahmad Nasir, Che Rosli (Institute of Electrical and Electronics Engineering (IEEE), 2009)
      Increasingly powerful integrated circuits are making an entire range of new applications possible. Recent technological advances are enabling a new generation of smart cameras that represent a quantum leap in sophistication. ...

    • Fast background subtraction for real time monitoring 

      Sundaraj, Kenneth; Retnasamy, V. (International Association of Science and Technology for Development (IASTED)/ACTA Press, 2007)
      We present an implementation for fast detection of moving objects in real time monitoring applications. We apply a common technique known as background subtraction for this purpose. Background subtraction can be defined ...

    • On stereo processing procedure applied towards blind navigation aid - SVETA 

      Balakrishnan, G.; Sainarayanan, G.; Nagarajan, Ramachandran; Sazali, Yaacob, Prof. Dr. (Institute of Electrical and Electronics Engineering (IEEE), 2005)
      This paper presents a portable traveling support system using stereo image processing for the visually impaired people's navigation. This system named as SVETA consists of a helmet molded with stereo cameras in the front, ...

    • Ultrasonic process tomographic imaging sensor: An approach utilising transceivers method 

      Mohd Hafiz, Fazalul Rahiman; Zulkarnay, Zakaria; Ruzairi, Abdul Rahim (Institute of Electrical and Electronics Engineering (IEEE), 2008-05-13)
      Direct analysis of the internal characteristics of process plant has become a widespread need in order to improve the design and operation of the equipment especially in liquid/gas two phase flows. In recent years, the ...

    • Ultrasonic tomography imaging simulation of two-phase homogeneous flow 

      Mohd Hafiz Fazalul, Rahiman; Zulkarnay, Zakaria; Ruzairi, Abdul Rahim; Wei, Nyap Ng (Emerald Group Publishing Limited, 2009-09)
      Purpose - The purpose of this paper is to present an implementation of ultrasonic tomography simulation to investigate the laminar flow of stratified liquid between water and oil. Design/methodology/approach - The velocity ...
