Matching pursuit for decomposition and approximation of ultrasonic pulse-echo wavelet and its application in ultrasonic nondestructive evaluation.
The estimation of the time of arrival (TOA) and/or time of flight of the ultrasonic echoes is essential in ultrasonic nondestructive evaluation. In this paper, matching pursuit method has been used to analyze noisy ultrasonic pulse-echo wavelet and decompose the noisy pulse-echo wavelet into unit-norm vectors. The error ratio of the mean square is used to monitor the acceptability of the unit-n...
متن کاملThe Development of Laser Ultrasonic Visualization Equipment and its Application in Nondestructive Inspection
We have developed a laser ultrasonic visualization(LUV) equipment. It can be used to study the ultrasound propagation in an arbitrary-shaped object, and also be used to the nondestructive inspection of materials and structures. The LUV equipment consists of the hardware and the software. The hardware consists of a pulsed laser, a scanning mirror (galvanometer scanner), an ultrasound sensor, a l...
متن کاملA study of the relationship among temperatures of surface features and its application in remote sensing study of Lut desert
Physical characteristics of different features in desert is a reflection of severe thermal and climatic conditions. In this paper, diurnal surface temperature patterns of important surface features in Lut Desert were studied and the relationship among different surfaces analyzed. Diurnal trend in surface temperature of surface types, marl, dark sand, light sand, salt-affected soil, soul at 10 c...
متن کاملThe Center Symmetry and Its Spontaneous Breakdown at High Temperatures
The Euclidean action of non-Abelian gauge theories with adjoint dynamical charges (gluons or gluinos) at non-zero temperature T is invariant against topologically non-trivial gauge transformations in the Z(N)c center of the SU(N) gauge group. The Polyakov loop measures the free energy of fundamental static charges (infinitely heavy test quarks) and is an order parameter for the spontaneous brea...
متن کاملconstruction and validation of translation metacognitive strategy questionnaire and its application to translation quality
like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
