Characterization of small defects using ultrasonic arrays: a scattering coefficient matrix approach
The ultrasonic scattering coefficient matrix defines the far field scattering behaviour of a defect as a function of incident and scattering angles. An ultrasonic array with a large aperture can then be used to interrogate a defect over a range of angles and hence extract parts of this matrix. Experimental results are presented using a commercial 64-element, 5-MHz array on two aluminium test sa...
متن کاملOn C3-Like Finsler Metrics
In this paper, we study the class of of C3-like Finsler metrics which contains the class of semi-C-reducible Finsler metric. We find a condition on C3-like metrics under which the notions of Landsberg curvature and mean Landsberg curvature are equivalent.
متن کاملA Novel Method for Ultrasonic Evaluation of Horizontal Defects Using Time-of-Flight Diffraction
Time-of-flight diffraction method (ToFD) is an amplitude-independent sizing method which is based on the measurement of time-of-flight of defect tip diffracted waves. Although ToFD can measure through-wall length of defect accurately, this method is not capable of measuring horizontal defect size. In this paper, a new ToFD method for evaluating horizontal planar defects is presented. The finite...
متن کاملCalculations of Elastic Wave Scattering from Voids and Crack-Like Defects by the Method of Optimal Truncation
Visscher's method of optimal truncation for solving elastic wave scattering problems has been applied to voids having surface cracks and sharp edges including some for which experimental data are becoming available. A number of interesting aspects of these results will be discussed and comparisons with existing experimental data presented.
متن کاملUsing Similarity Metrics for Matching Lifelong Learners
The L4All system provides an environment for the lifelong learner to access information about courses, personal development plans, recommendation of learning pathways, personalised support for planning of learning, and reflecting on learning. Designed as a web-based application, it offers lifelong learners the possibility to define and share their own timeline (a chronological record of their r...
