(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 ...
Initial study on optical fiber array to produce particle size information for hydraulic process
(Springer Berlin Heidelberg, 2013-08)
This paper presents the results of investigations carried out to determine the feasibility of using optical fibers to produce particle size information of hydraulic processes. The results have been obtained using a static ...
Optical tomography: Velocity profile measurement using orthogonal and rectilinear arrangements
(Elsevier Ltd., 2012-03)
In tomography applications, flow velocity is an important flow characteristic for analysis. Excessively high particle velocity will cause high energy consumption, severe pipeline wear and particle degradation. This paper ...

The ability to implement fan beam projection in parallel view in an optical tomography setup is one of the novelties of this research. This design involves a sensor jig specifically designed for parallel applications that ...
Optical tomography: Image improvement using mixed projection of parallel and fan beam modes
(Elsevier Ltd, 2013-07)
Mixed parallel and fan beam projection is a technique used to increase the quality images. This research focuses on enhancing the image quality in optical tomography. Image quality can be defined by measuring the Peak ...
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 ...
Design consideration for front-end system in ultrasonic tomography
(Penerbit UTM Press, 2013)
The hardware development of the ultrasonic tomography comprises three main parts; the sensor unit, electronic measurement circuits combined with a data acquisition system and finally the display unit. The research done is ...
Modelling ultrasonic sensor for gas bubble profiles characterization of chemical column
(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 ...
