A review of tomography system
(Penerbit UTM Press, 2013)
Tomography system is a method that being used to reconstruct a cross sectional image in vessel or pipeline. This method is widely used in medical and industrial fields. The aim of this paper is to provide an overview of ...
Study of the effect of brightness after penetration of light from a lens
(Penerbit UTM Press, 2013)
There are many types of component that are able to produce light and the light is produced based on the angle and wavelength of the lens. Light penetration depends on the type of material used. The tests are done using ...
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 ...
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 ...
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 ...
Application study on bubble detection in a metallic bubble column using electrical resistance tomography
(Penerbit UTM Press, 2014)
Electrical RESISTANCE tomography (ERT) has been chosen as the field of study because of its advantages of being low COST, suitable for various kinds and sizes of pipes and vessels, having no radiation hazard, and being ...
Gas hold-up profiles determination by means of ultrasonic transducer
(Penerbit UTM Press, 2014)
This paper details a work carried out to measure gas hold-up profiles in a liquid column using a pair of ultrasonic transducer. The gas hold-up profiles from 1.85 mm to 7.7 mm diameter are of interest in this investigation. ...
