We derive an approximate maximum a posteriori (MAP) method for detecting NDE defect signals using hidden Markov random fields (HMRFs). In the proposed HMRF framework, a set of spatially distributed NDE measurements is assumed to form a noisy realization of an underlying random field that has a simple structure with Markovian dependence. Here, the random field describes the defect signals to be ...

CARDIAC arrest is a frightening complication which may confront a surgeon at any operation. It is fortunate that it is relatively uncommon, but there is a danger of false security. Eye surgeons face this complication less frequently than general or thoracic surgeons, but few ofthose who have practised for many years have not met cases of actual or threatened cardiac arrest.

In this paper, we study the key recovery problem for the C∗ scheme and generalisations where the quadratic monomial of C∗ (the product of two linearized monomials) is replaced by a product of three or more linearized monomials. This problem has been further generalized to any system of multivariate polynomials hidden by two invertible linear maps and named the Isomorphism of Polynomials (IP ) p...

The bimetallic joining elements were designed for lap joints of thin metallic (Fe-Fe, Fe-Al) as well – nonmetallic (Fe-PMMA, Al-PMMA) sheets by Resistance Element Welding (REW). Cu tubes with an outer diameter 4 mm, wall thickness 0.5 and a length 11 mm filled solder Sn60Pb40 used the producing. required shape is obtained cold forming. Simulation ANSYS software was chosen optimization forming p...

Abstract. We report a new sampling strategy for collecting representative samples of drill core. By splitting the core with diamond saw into working and archive halves, cuttings constitute “channel” sample, best subsample from which to obtain an average mineralogical geochemical composition apply this procedure lower oceanic crust in Hess Deep obtained during Expedition 345 Integrated Ocean Dri...
