Magnetic induction tomography: Receiver circuit and its design criteria
(Penerbit UTM Press, 2013-07)
This paper discusses the receiver circuit and criteria for component selection towards the application of a real-time magnetic induction tomography system. Component selection plays an important role since image reconstruction ...
Magnetic induction tomography modeling in biological tissue imaging using two-port network technique
(International Frequency Sensor Association (IFSA), 2013)
Magnetic Induction Tomography (MIT) is a non-invasive and non-intrusive imaging technique which interested in passive electrical properties of a material that are permittivity, permeability and conductivity. MIT applies ...
Imaging of a metallic object using magnetic induction tomography
(International Frequency Sensor Association Publishing (IFSA), 2013-08)
This paper describes the metallic imaging results from magnetic induction tomography (MIT) hardware. Copper phantom, representing a high conductivity material, was placed into the measurement region of interest. The initial ...
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 ...
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 ...
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 ...
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 ...
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 ...
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. ...
