Abstract Macrosegregation presents a considerable defect in the continuous casting of billets and can critically affect final properties product. The numerical modelling help to predict better understand segregation flow patterns inside mould. process is modelled with physical model described by set conservation equations describing t heat transfer, turbulence, fluid flow, solidification segreg...

Digital image correlation systems provide the motion of material points on surface a specimen or component. Commonly, local interpolation concepts are chosen to determine in-plane strains principal stretches. However, this approach yields discontinuous fields. In paper, global concept, particular, radial basis functions is considered displacement and strain field overcome underlying problem dis...

The strategic logistics of agricultural production and storage aggregates information related to storage. In this sense, time, location, distance from producer consumer markets are considered, emphasizing the importance grain logistics. Natural Neighbor multiquadric equation spatial interpolation methods used predict these variables value at non-sampled locations, for asymmetric categorical dat...

Elliptic boundary value problems (BVPs) are widely used in various scientific and engineering disciplines that involve finding solutions to elliptic partial differential equations subject certain conditions. This article introduces a novel approach for solving BVPs using an artificial neural network (ANN)-based radial basis function (RBF) collocation method. In this study, the backpropagation i...

A review of interpolation to values of a function f(x), x 2 R d , by radial basis function methods is given. It addresses the nonsingularity of the interpolation equations, the inclusion of polynomial terms, and the accuracy of the approximation sf, where s is the interpolant. Then some numerical experiments investigate the situation when the data points are on a low dimensional nonlinear manif...

in this paper, we propose a new numerical method for solution of urysohn two dimensional mixed volterra-fredholm integral equations of the second kind on a non-rectangular domain. the method approximates the solution by the discrete collocation method based on inverse multiquadric radialbasis functions (rbfs) constructed on a set of disordered data. the method is a meshless method, because it i...
