To test this hypothesis, the authors gave participants evaluative feedback (e.g., succe...
متن کاملHalf-Space Radiation by EMAT's
A Green's function calculation of the far field radiation patterns of EMAT's is presented. The approach is based upon (a) closed form expressions for the eddy current and static magnetic field distributions, established by the EMAT, which react to produce the driving Lorentz forces and (b) a Green's function derived from the steepest descent approximation to the far field response of an arbitar...
متن کاملBetter Correspondence by Registration
Accurate image correspondence is crucial for estimating multiple-view geometry. In this paper, we present a registration-based method for improving accuracy of the image correspondences. We apply the method to fundamental matrix estimation under practical situations where there are both erroneous matches (outliers) and small feature location errors. Our registration-based method can correct fea...
متن کاملHalf and half nails
This 68-year-old patient with Stage 4 chronic kidney disease was reviewed in our low clearance clinic 2 months after formation of a left arteriovenous fistula. The prominent ‘half-and-half’ appearance of his nails was noted. Nail disorders are common in chronic renal failure, affecting up to 70% of haemodialysis patients [1]. Half-and-half or Lindsay nails [2], where the proximal half of the na...
