    • Control follower robot speed based on ultrasonic echo 

      Muhammed, S. Salim; Mohd Fareq, Abd Malek, Dr.; R.B.W., Heng; Khairudi, Mohd Juni; Naseer Sabri, Salim (Universiti Malaysia Perlis (UniMAP), 2012-06-18)
      In this research the dynamic speed profile generation system made up of fuzzy logic and ultrasonic sensors is evaluated. The echo power signal measurement permits us to endow the robot with capacity for pursuing and ...

    • The front-end hardware design issue in ultrasonic tomography 

      Mohd. Hafiz, Fazalul Rahiman; Rahim, R. A.; Mohd Nasir, Ayob (IEEE, 2010-07)
      This paper explains the front-end hardware design for ultrasonic tomography. The ultrasonic tomography system presented in this paper uses a noninvasive sensing technique with transmission-mode approach for investigating ...

    • Gas hold-up profiles measurement using ultrasonic sensor 

      Mohd Hafiz, Fazalul Rahiman; Ruzairi, Abdul Rahim, Prof. Dr.; Herlina, Abdul Rahim, Dr. (Institute of Electrical and Electronics Engineers (IEEE), 2011-02)
      In this letter, we present a work carried out to measure gas hold-up profiles in a liquid column using a pair of ultrasonic sensors. The gas hold-up profiles from 1.85 to 7.7 mm in diameter are of interest in this ...

    • GPS controlled autonomous walking robot with ultrasonic sensor 

      Bukhari, Ilias; R. Nagarajan; Sazali, Yaacob; Sundaraj, Kenneth (Kolej Universiti Kejuruteraan Utara Malaysia (KUKUM)School of Mechatronic Engineering, 2006-12)
      The Global Positioning System (GPS) is normally attached to modern cars. It is used to indicate the driver by voice signal to understand the current location and the directions to reach the target location In this research ...

    • Modelling ultrasonic sensor for gas bubble profiles characterization of chemical column 

      Mohd Hafiz, Fazalul Rahiman, Dr.; Ruzairi, Abdul Rahim, Prof. Dr. ; Herlina, Abdul Rahim, Dr.; Nor Muzakkir, Nor Ayob; Elmy Johana, Mohamad, Dr.; Zulkarnay, Zakaria (Elsevier B.V., 2013)
      In this paper, we present a modelling and experimental work to characterize gas bubble profiles in chemical column using a pair of ultrasonic sensor. The gas bubble profiles from 2.90 mm to 7.50 mm diameter are of interest ...

    • Novel adjacent criterion method for improving ultrasonic imaging spatial resolution 

      Mohd Hafiz, Fazalul Rahiman, Dr; Ruzairi, Abdul Rahim, Prof. Dr.; Herlina, Abdul Rahim, Dr.; Nor Muzakkir, Nor Ayob (Institute of Electrical and Electronics Engineers (IEEE), 2012)
      In this letter, we present a novel approach for improving spatial resolution in ultrasonic tomography. The proposed technique modifies a Back-projection (BP) algorithm in reconstructing tomography images. We used 32-ultrasonic ...

    • Small gas component detection using ultrasonic transmission-mode tomography system 

      Nor Muzakkir, Nor Ayob; Muhammad Jaysuman, Pusppanathan; Ruzairi, Abdul Rahim, Prof. Dr.; Mohd Hafiz, Fazalul Rahiman, Dr.; Fazlul Rahman, Mohd Yunus; Zulkarnay, Zakaria; Goh, Chiew Loon; Salinda, Buyamin, Dr.; Nasarudin, Ahmad; Yusri, Md. Yunos, Dr.; Norhaliza, Abdul Wahab, Assoc. Prof. Dr. (Penerbit UTM Press, 2014)
      This paper presents the development of an ultrasonic transmission-mode tomography system for the detection of small gas components by using higher frequency ultrasonic transducers. The selection of the transducer is important ...

    • Ultrasonic transducer kit for bacteria growth monitoring system 

      H. N. A. Salwa; Sundaraj, Kenneth, Prof. Madya; Azian Azamimi, Abdullah; Mohamed Zulkali, Mohamed Daud (Institute of Electrical and Elctronics Engineering (IEEE), 2010-05-21)
      In food process industries, sometimes there was food contamination even when it is still in process. Same as other industries when involved with liquid, product contamination which caused by bacteria can affect the quality ...
