Damage detection in steel plates using discrete cosine transformation techniques and artificial neural network
(Universiti Malaysia Perlis, 2009-10-11)
In this paper, a simple method for crack identification in steel plates based on the Frame Energy based Discrete Cosine
Transformation [DCT] moments is presented. A simple experimental procedure is also proposed to measure ...
Development of parallel and fan-shaped beam mixed-projection optical tomography
(International Frequency Sensor Association Publishing (IFSA), 2012-05)
Parallel and fan shaped beam are two common projections that had been used widely in
optical tomography system. These projections never have been merged before in the process of
tomography area. In this paper, some ...
Multiphase ultrasonic tomography technique for homogeneous and Non-homogeneuos media identification
(Intel Tech Sdn. Bhd./Pac Tech Sdn. Bhd./Universiti Sains Malaysia (USM), 2009)
Multiphase flow characterization is an important task for monitoring, measuring or controlling industrial processes. This can be done by means of process tomography. The use of tomographic techniques has been used within ...
Hardware developments of an ultrasonic tomography measurement system
(International Frequency Sensors Association (IFSA), 2011-01)
This research provides new technique in ultrasonic tomography by using ultrasonic transceivers instead of using separate transmitter-receiver pair. The numbers of sensors or transducers used to acquire data plays an important ...
