Contour integration The best known example of this iscontour integration. The integral of a complex function along a closed path doesn’t depend on the path itself but on certain values (“residues”) associated with places inside the path where the function has a singularity. This means that ...

Contour integration is the process of calculating the values of a contour integral around a given contour in the complex plane. As a result of a truly amazing property of holomorphic functions, such integrals can be computed easily simply by summing the values of the complex residues inside the...
Contour Integration 8.1 Prelude In this, the penultimate chapter of the book, I’ll give you a really fast, stripped- down, ‘crash-course’ presentation of the very beginnings of complex function theory, and the application of that theory to one of the gems of mathematics: contour integratio...
Based on the elastodynamic responses of stress [[sigma].sub.ij] (i, j = 1, 2, 3) and displacement [u.sub.i] (i=1, 2, 3), which are obtained using the technique of explicit time integration in FE analysis of the cracked body, the dynamic J-integral (denoted as [J.sup.d]) ...

Since the perturbed solution is at a minimum, the integration terms in Eq. (6.24) must be identically zero (6.25)∫s=0s=1α(s)dx∧(s)dsdδx(s)ds+β(s)d2x∧(s)ds2d2δx(s)ds2+δx(s)2∂Eedge∂x|x∧,y∧ds=0 (6.26)∫s=0s=1α(s)dy∧(s)dsdδy(s)ds+β(s)d2y∧...
For the case of the image gradient ∇I, however, since we will be using numerical integration, it is more convenient to define it as a 2D function defined on Ω. This function is piecewise constant in each triangle of the triangulation and its value is the gradient of the plane that ...
This paper provides an algorithm for partitioning gray-scale images into disjoint regions of coherent brightness and texture. Natural images contain both textured and untextured regions, so the cues of contour and texture differences are exploited simultaneously. Contours are treated in the intervening ...
