Optical tomography hardware development for solid gas measurement using mixed projection
(Elsevier Ltd, 2013-10)
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 ...
Measurement of the content of water using light penetration
(Penerbit UTM Press, 2014)
In this paper we use an electronic component to produce light which is applied in testing soft tissue penetration. We used bio tissue, a slice of apple, and non-bio tissue, paper. The voltage could be adjusted to brighten ...
Study and Design of an Ultrasonic Flow Tomographic Front-End Multi Level Measurement System
(Penerbit UTM Press, 2014)
With the rapid evolution of electro-acoustical technology, ultrasonic tomography has made considerable progress in industry. An ultrasonic tomography system provides non-invasive and non-intrusive flow visualisation that ...
Simulative study of two-phase homogenous and isotropic media imaging using magnetic induction tomography
(Penerbit UTM Press, 2014)
Magnetic induction tomography is a new non-invasive technology, based on eddy current discovery of electromagnetic induction by Michael Faraday. Through this technique, the passive electrical properties distribution of an ...
Image fusion using fuzzy logic pixel fusion for dual modality tomography system
(Penerbit UTM Press, 2014)
Process tomography has been widely investigated and developed over time. The aim of this method is to measure the cross-sectional distribution of multiphase flow parameters based on its sensing technique. These single ...
Small gas component detection using ultrasonic transmission-mode tomography system
(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 ...
