    • Quantifying scheme for detection heterogeneous phase in a pipe vessel 

      Mohd Rizal, Manan; Muhammad Naufal, Mansor; Mohd Hafiz Fazalul, Rahiman; Sazali, Yaacob, Prof. Dr.; Ruzairi, Abdul Rahim (Science Academy Publisher, 2011-03)
      This paper describes the different ultrasonic tomography for multiphase flow such as liquid/gas flow which commonly found in chemical columns and industrial pipelines. The information obtained through this research has ...

    • Real time mass flow rate measurement using multiple fan beam optical tomography 

      Ruzairi, Abdul Rahim; Lai, Chen Leong; Kok, San Chan; Mohd Hafiz Fazalul, Rahiman; Jon, Fea Pang (Elsevier, 2008)
      This paper presents the implementing multiple fan beam projection technique using optical fibre sensors for a tomography system. From the dynamic experiment of solid/gas flow using plastic beads in a gravity flow rig, the ...

    • Simulation of the two-phase liquid – gas flow through ultrasonic transceivers application in ultrasonic tomography 

      Zulkarnay, Zakaria; Mohd Hafiz, Fazalul Rahiman; Ruzairi, Abdul Rahim (International Frequency Sensor Association (IFSA), 2010-01-29)
      In this paper, ultrasonic transmission mode tomography was used to visualize the two phase liquid/gas flow in a pipe/vessel. The sensing element consists of 8, 16 and 32 units ultrasonic transceivers were used to cover ...

    • Single channel magnetic induction spectroscopy technique for fetal acidosis detection 

      Shazwani, Sarkawi; Zulkarnay, Zakaria; Jurimah, Abdul Jalil; Ibrahim, Balkhis; Mohamad Aliff, Adul Rahim; Nazahah, Mustafaa; Ruzairi, Abdul Rahim; Mohd Hafiz, Fazalul Rahiman; Zaridah, Shafie (Penerbit UTM Press, 2016)
      Current fetal acidosis diagnosis needs an invasive measurement which required a doctor to puncture fetal scalp to acquire blood pH. This method introduced risk to the fetal which fetal scalp may bruise and infected. This ...

    • A study of a two phases medium in pipe vessel using gaussian filter method and k-NN classifier 

      Mohd Rizal, Manan; Muhammad Naufal, Mansor; Ruzairi, Abdul Rahim; Sazali, Yaacob, Prof. Dr.; Mohd Hafiz, Fazalul Rahiman, Dr. (IOS Press, 2013-07-03)
      In this paper we present the existence and uniqueness of solutions to the stochastic problem to determine two phase level of gas and water in the industrial pipe line. In order to distinguish the level phases in a vessel ...

    • 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 ...
