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 ...
A complete system modelling of piezoelectric energy harvester (PEH) with silicon carbide (SiC) used as cantilever base
(Penerbit UTM Press, 2014)
Silicon carbide (SiC) is a material that possesses hardness and robustness to operate under high temperature condition. This work is a pilot in exploring the feasibility of cubic piezo element on the SiC wafer with integrated ...
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 ...
Development of a non-invasive bio-acoustics measurement system for assessing articular cartilage knee joint problem
(Penerbit UTM Press, 2014)
A technique in measuring and recording of bio-acoustics signals for the assessment of physiological of knee joint articular cartilage conditions has been developed. Currently, invasive technique such as knee arthroscopy ...
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. ...
Electrical resistance tomography: a review of the application of conducting vessel walls
(Elsevier, 2014-03)
Despite decades of research, the study on tomography continues to be a subject of great scientific interest. Amongst all the kinds of tomography available, electrical resistance tomography (ERT) has been chosen as the field ...
A new hybrid intelligent system for accurate detection of Parkinson's disease
(Elsevier, 2014-03)
Elderly people are commonly affected by Parkinson's disease (PD) which is one of the most common neurodegenerative disorders due to the loss of dopamine-producing brain cells. People with PD's (PWP) may have difficulty in ...
Gesture recognition based on bayesian inference of distributed arm trajectory
(American Scientific Publishers, 2014-01)
The use of human gestures has become an important part of human-computer interaction (HCI) and is receiving more and more attentions in the recent years, which allows users to communicate with machines in the natural way, ...
Edge detection algorithm for enhancement of linear back projection tomographic images
(Penerbit UTM Press, 2014)
Process tomography (PT) is a leading technique for multiphase flow measurement and flow monitoring systems in various fields. PT has the advantage of interpreting acquired measurement data and transforming it into visual ...
