This note extends previous work of the authors modelling the Wheatley valve by using six intersecting and contiguous ellipses to obtain a generalized mathematical representation of the Wheatley valve: this provides a number of free parameters that co

Uniform Convergence of a Collocation Method for the Numerical Solution of Cauchy-Type Singular Integral Equations: A Generalization

Autor: J. A. Cuminato

Publikováno v: IMA Journal of Numerical Analysis. 12:31-45

The uniform convergence of a collocation method for solving Cauchy-type singular integral equations is analysed in detail. This method uses a class of orthogonal polynomials, derived from the given equation, as basis elements and the zeros of the Che

A multiresolution flow-based multiphase image segmentation

Autor: E. Z. Barcelos, J. A. Cuminato, C. A. Z. Barcelos

Publikováno v: SMC

In this work a variational model is proposed for simultaneous smoothing and multiphase image segmentation. By assuming that the pixel intensities are independent samples from a mixture of Gaussians, and by interpreting the phase fields as probabiliti

A SEMI-IMPLICIT SCHEME FOR SOLVING INCOMPRESSIBLE VISCOUS FREE SURFACE FLOWS

Autor: C. M. Oishi, J. A. Cuminato, V. G. Ferreira, M. F. Tomé, A. Castelo, N. Mangiavacchi

Publikováno v: Revista de Engenharia Térmica. 4:106

The present work is concerned with a numerical method for solving the two-dimensional time-dependent incompressible Navier-Stokes equations in the primitive variables formulation. The diffusive terms are treated by Implicit Backward and Crank-Nicolso
