Spectral density estimation for stationary stable random fields

Rachid Sabre (1995)

Applicationes Mathematicae

Similarity:

We consider a stationary symmetric stable bidimensional process with discrete time, having the spectral representation (1.1). We consider a general case where the spectral measure is assumed to be the sum of an absolutely continuous measure, a discrete measure of finite order and a finite number of absolutely continuous measures on several lines. We estimate the density of the absolutely continuous measure and the density on the lines.

Numerical analysis of a semi-implicit DDFV scheme for the regularized curvature driven level set equation in 2D

Angela Handlovičová, Dana Kotorová (2013)

Kybernetika

Similarity:

Stability and convergence of the linear semi-implicit discrete duality finite volume (DDFV) numerical scheme in 2D for the solution of the regularized curvature driven level set equation is proved. Numerical experiments concerning comparison with exact solution and image filtering problem using proposed scheme are included.
