The front-end hardware design issue in ultrasonic tomography
(IEEE, 2010-07)This paper explains the front-end hardware design for ultrasonic tomography. The ultrasonic tomography system presented in this paper uses a noninvasive sensing technique with transmission-mode approach for investigating ... -
Gas hold-up profiles measurement using ultrasonic sensor
(Institute of Electrical and Electronics Engineers (IEEE), 2011-02)In this letter, we present a work carried out to measure gas hold-up profiles in a liquid column using a pair of ultrasonic sensors. The gas hold-up profiles from 1.85 to 7.7 mm in diameter are of interest in this ... -
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 ... -
Novel adjacent criterion method for improving ultrasonic imaging spatial resolution
(Institute of Electrical and Electronics Engineers (IEEE), 2012)In this letter, we present a novel approach for improving spatial resolution in ultrasonic tomography. The proposed technique modifies a Back-projection (BP) algorithm in reconstructing tomography images. We used 32-ultrasonic ... -
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 ...
