Perturbed Fourier uniqueness and interpolation results in higher dimensions
Joao Pedro Gonçalves Ramos, Martin Peter Stoller
We obtain new Fourier interpolation and uniqueness results in all dimensions, extending methods and results by the first author and M. Sousa [11] and the second author [12]. We show that the only Schwartz function which, together with its Fourier transform ...
ACADEMIC PRESS INC ELSEVIER SCIENCE2022Geometric ergodicity for some space-time max-stable Markov chains
Max-stable processes are central models for spatial extremes. In this paper, we focus on some space-time max-stable models introduced in Embrechts et al. (2016). The processes considered induce discrete-time Markov chains taking values in the space of cont ...
ELSEVIER SCIENCE BV2019Calculus of variations: A differential form approach
We study integrals of the form integral(Omega) f(d omega(1), ..., d omega(m)), where m >= 1 is a given integer, 1
WALTER DE GRUYTER GMBH2019Neural BTF Compression and Interpolation
The Bidirectional Texture Function (BTF) is a data-driven solution to render materials with complex appearance. A typical capture contains tens of thousands of images of a material sample under varying viewing and lighting conditions. While capable of fait ...
WILEY2019Generalized Poisson Summation Formulas for Continuous Functions of Polynomial Growth
Michaël Unser, John Paul Ward, Quy Ha Nguyen
The Poisson summation formula (PSF) describes the equivalence between the sampling of an analog signal and the periodization of its frequency spectrum. In engineering textbooks, the PSF is usually stated formally without explicit conditions on the signal f ...
2017A Discontinuous Galerkin Reduced Basis Element Method For Elliptic Problems
Alfio Quarteroni, Paolo Pacciarini
We propose and analyse a new discontinuous reduced basis element method for the approximation of parametrized elliptic PDEs in partitioned domains. The method is built upon an offline stage (parameter independent) and an online (parameter dependent) one. I ...
Edp Sciences S A2016Calculus of Variations for Differential Forms
In this thesis we study calculus of variations for differential forms. In the first part we develop the framework of direct methods of calculus of variations in the context of minimization problems for functionals of one or several differential forms of th ...
EPFL2016Dust grain coagulation modelling: From discrete to continuous
In molecular clouds, stars are formed from a mixture of gas, plasma and dust particles. The dynamics of this formation is still actively investigated and a study of dust coagulation can help to shed light on this process. Starting from a pre-existing discr ...
Elsevier Science Bv2016Extremal behavior of squared Bessel processes attracted by the Brown-Resnick process
The convergence of properly time-scaled and normalized maxima of independent standard Brownian motions to the Brown-Resnick process is well-known in the literature. In this paper, we study the extremal functional behavior of non-Gaussian processes, namely ...
Elsevier Science Bv2015Time accurate partitioned algorithms for the solution of fluid-structure interaction problems in haemodynamics
Fabio Nobile, Christian Vergara
In this work we deal with the numerical solution of the fluid-structure interaction problem arising in the haemodynamic environment. In particular, we consider BDF and Newmark time discretization schemes, and we study different methods for the treatment of ...
