Poisson intensity estimation for tomographic data using a wavelet shrinkage approach
We consider a two-dimensional problem of positron emission tomography where the random mechanism of the generation of the tomographic data is modeled by Poisson processes. The goa...

Matrix interpretation of multiple orthogonality
Abstract: In this work we give an interpretation of a (s(d + 1) + 1)-term recurrence relation in terms of type II multiple orthogonal polynomials. We rewrite this recurrence relati...

Guided Surface Waves on One- and Two-Dimensional Arrays of Spheres
Guided acoustic waves propagating along one- and two-dimensional arrays of rigid spheres are studied semi-analytically. The quasi-periodic wave field is constructed as a superposi...

Global Stability Analysis of Fluid Flows using Sum-of-Squares
This paper introduces a new method for proving global stability of fluid flows through the construction of Lyapunov functionals. For finite dimensional approximations of fluid...
