A quoi sert la modalisation a posteriori ?

open access: yesAnglophonia, 2015
This paper explores Paul Larreya’s concept of a posteriori modalisation. We first come back on Larreya’s distinction between a priori and a posteriori modalisation and suggest that his typology of the uses and functions of a posteriori modalisation ...

A Posteriori L_∞ (L_2 )+L_2 (H^1 )–Error Bounds in Discontinuous Galerkin Methods For Semidiscrete Semilinear Parabolic Interface Problems

open access: yesمجلة بغداد للعلوم, 2021
The aim of this paper is to derive a posteriori error estimates for semilinear parabolic interface problems. More specifically, optimal order a posteriori error analysis in the - norm for semidiscrete semilinear parabolic interface problems is derived by

An O(h6) cubic spline interpolating procedure for harmonic functions [PDF]

open access: yes, 1989
An O(h6) method for the interpolation of harmonic functions in rectangular do- mains is described and analysed. The method is based on an earlier cubic spline tech- nique [7], and makes use of recent results concerning the a posteriori correction of ...

Considerations on a posteriori probability

open access: yesStatistica, 2015
In this first paper of 1911 relating to the sex ratio at birth, Gini repurposed a Laplace’s succession rule according to a Bayesian version. The Gini's intuition consisted in assuming for prior probability a Beta type distribution and introducing the ...

An Efficient Gaussian Filter Based on Gaussian Symmetric Markov Random Field

open access: yesIEEE Access, 2022
This article presents a new image denoising algorithm that uses Gaussian Symmetric Markov random fields based on maximum a posteriori estimation. First, an image denoising model based on Gaussian Symmetric Markov random fields is built, and the image ...

High-throughput calculations of charged point defect properties with semi-local density functional theory—performance benchmarks for materials screening applications

open access: yesnpj Computational Materials, 2023
Calculations of point defect energetics with Density Functional Theory (DFT) can provide valuable insight into several optoelectronic, thermodynamic, and kinetic properties. These calculations commonly use methods ranging from semi-local functionals with

Robust a priori and a posteriori error analysis for the approximation of Allen–Cahn and Ginzburg–Landau equations past topological changes [PDF]

open access: yes, 2010
A priori and a posteriori error estimates are derived for the numerical approximation of scalar and complex valued phase field models. Particular attention is devoted to the dependence of the estimates on a small parameter and to the validity of the ...

A class of cubic and quintic spline modified collocation methods for the solution of two-point boundary value problems [PDF]

open access: yes, 1987
This paper is concerned with the study of a class of methods for solving second and fourth-order two-point boundary-value problems. The methods under consideration are modifications of the standard cubic and quintic spline collocation techniques, and ...

Porównanie bayesowskich modeli Copula-AR(1)-GARCH(1,1) z asymetrycznością rozkładów warunkowych

open access: yesZeszyty Naukowe Uniwersytetu Ekonomicznego w Krakowie, 2018
Celem artykułu było formalne porównanie mocy wyjaśniającej dwuwymiarowych bayesowskich modeli Copula-GARCH z warunkowym skośnym oraz symetrycznym rozkładem t-Studenta na przykładzie danych pochodzących z polskiego rynku finansowego.
