A study on forward and inverse problems for an ultrasonic tomography
(Penerbit UTM Press, 2014)This paper studies the solution for inverse and forward problems for an ultrasonic tomography. Transmission-mode approach has been used for sensing the liquid/gas two-phase flow, which is a kind of strongly inhomogeneous ... -
Study on wireless sensor based industrial tomography systems
(International Frequency Sensor Association Publishing (IFSA), 2013)Wireless sensor technologies are promising in the field of industrial tomography system, to visualize the cross-sectional images of an industrial flow process. The aim of the paper is to review the technical and scientific ... -
Supasorb Adsorbents for Treatment of Dyespolluted Wastewater
(Malaysian Invention and Design Society (MINDS), 2007)Supasorb is a carbon-based adsorbent designed to treat dyes polluted waterwaste discharge from industry. -
Tomographic reconstruction of a multi-attenuation phantom by means of ultrasonic method
(Springer Science+Business Media B.V., 2012)This paper presents a work on tomography reconstruction of a multi-attenuation phantom by means of ultrasonic method. A transmission-mode approach has been used for the sensing modality. The reconstruction has been conducted ... -
Ultrasonic process tomographic imaging sensor: An approach utilising transceivers method
(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 - image reconstruction algorithms
(International Journal of Innovative Computing, Information and Control (IJICIC), 2012-01)This paper focuses on image reconstruction algorithms for use in ultrasonic tomography. There are three types of algorithms namely Linear Back Projection, Hybrid Reconstruction and Hybrid Binary Reconstruction that are of ... -
Ultrasonic tomography imaging for liquid-gas flow measurement
(International Frequency Sensor Association (IFSA), 2013)This research was carried out to measure two-phase liquid - gas flow regime by using a dual functionality ultrasonic transducer. Comparing to the common separated transmitter-receiver ultrasonic pairs transducer, the dual ... -
Ultrasonic tomography imaging for two-phase flow
(Universiti Malaysia Perlis (UniMAP)Pejabat Timbalan Naib Canselor (Penyelidikan dan Inovasi), 2008-07)Real-time process monitoring is important in many areas of industry and scienti c research concerning liquid/gas two-phase ow, and is closely related to accurate measurement and control of hydrodynamic parameters such ... -
Ultrasound processing circuitry for ultrasonic tomography
(Universiti Malaysia Perlis, 2009-10-11)The development of an ultrasonic transmission tomography system is described. The system is intended for the imaging of two component flows (such as gas/water) inside pipes of industrial processes. Transmission-mode ... -
Underwater ground mapping for flood disaster using ultrasonic sensor
(Penerbit UTM Press, 2016)Search and Rescue (SAR) team used dip stick to measure the water depth and identify the badly eroded area and a guide line will be placed to assist them. However, ground erosion is unpredictable coupled with unknown sizes ...
