Fast computation of optimized electrode arrays for 2D resistivity surveys
Four different methods to automatically select an optimal set of array configurations that gives the maximum resolution of the subsurface with a limited number of measurements for 2D electrical imaging surveys were tested. The first method (CR method) directly calculates the change in the model resolution for each new array added to the base data set, and uses this to select array configuration...
متن کامل2D arrays and Volume Focusing Combined Inspection Technique
2D arrays, also called matrix arrays, have recently appeared on the market providing key advantages to improve inspection methods and results. In particular, point focus ability, tilt and skew angle scanning are both promising features that new electronic equipment makers are promoting. Volume Focusing, when used with 2D arrays, yields high inspection speeds, interaction of UT waves and flaws, ...
متن کاملSpot Weld Analysis With 2D Ultrasonic Arrays
This paper describes a threefold method of testing the performance of an array-based ultrasonic tool for nondestructive testing of spot welds. The tool is described in its capabilities, use, and advantages over existing counterparts. Performance testing for and the results from carrying out the testing are described. The three performance testing methods include 1) the use of calibrated samples...
متن کاملReceptor arrays optimized for natural odor statistics.
Natural odors typically consist of many molecules at different concentrations. It is unclear how the numerous odorant molecules and their possible mixtures are discriminated by relatively few olfactory receptors. Using an information theoretic model, we show that a receptor array is optimal for this task if it achieves two possibly conflicting goals: (i) Each receptor should respond to half of ...
متن کاملSmall microphone arrays with optimized directivity for speech enhancement
In many situations of digital speech communication (e.g. hands-free telephony or electronic hearing aids) the speech signal picked up by the microphone is disturbed by acoustic background noise. Therefore, adaptive ltering techniques which aim at the reduction of the disturbing noise are subject of current research activities (e.g. [1]). Although some of the already known adaptive techniques { ...
