Maximum-a-Posteriori Estimation with Bayesian Confidence Regions [PDF]

SIAM Journal of Imaging Sciences, 2016
Solutions to inverse problems that are ill-conditioned or ill-posed may have significant intrinsic uncertainty. Unfortunately, analysing and quantifying this uncertainty is very challenging, particularly in high-dimensional problems.

Ignorance, sciences et droit

Cahiers Droit, Sciences & Technologies
To what extent do the a priori and a posteriori approach to ignorance inform us about the relationship between science and law ? This paper sets out to explore the answers in five stages. How are we ignorant ?

A Posteriori Error Estimates for the Generalized Overlapping Domain Decomposition Methods

Journal of Applied Mathematics, 2012
A posteriori error estimates for the generalized overlapping domain decomposition method (GODDM) (i.e., with Robin boundary conditions on the interfaces), for second order boundary value problems, are derived.

SENIOR FORMS STUDENTS’ COGNITIVE ACTIVITY DEVELOPMENT IN ENGLISH TEXTUAL ACTIVITY

Вестник Тамбовского университета. Серия: Гуманитарные науки, 2016
It is devoted to considering a question of using popular-science texts as the main means of senior forms students’ cognitive activity development. In our work we base on some principles of I.

Constants within Error Estimates for Legendre-Galerkin Spectral Approximations of Control-Constrained Optimal Control Problems

Abstract and Applied Analysis, 2014
Explicit formulae of constants within the a posteriori error estimate for optimal control problems are investigated with Legendre-Galerkin spectral methods. The constrained set is put on the control variable.

Towards a structural-functional classification of fynbos: a comparison of methods

Bothalia: African Biodiversity & Conservation, 1979
The need for a classification of the vegetation of the fynbos region is stressed. In the present work we have evaluated some structural-functional approaches that could be used to classify and describe fynbos.

A Model to Improve Granular Temperature in CFD-DEM Simulations

Energies, 2020
CFD-DEM (computational fluid dynamic-discrete element method) is a promising approach for simulating fluid–solid flows in fluidized beds. This approach generally under-predicts the granular temperature due to the use of drag models for the average drag ...

A priori and a posteriori $W^{1,\infty}$ error analysis of a QC method for complex lattices [PDF]

, 2012
In this paper we prove a priori and a posteriori error estimates for a multiscale numerical method for computing equilibria of multilattices under an external force. The error estimates are derived in a $W^{1,\infty}$ norm in one space dimension.

Guaranteed, Locally Space-Time Efficient, and Polynomial-Degree Robust a Posteriori Error Estimates for High-Order Discretizations of Parabolic Problems [PDF]

SIAM Journal on Numerical Analysis, 2016
We consider the a posteriori error analysis of approximations of parabolic problems based on arbitrarily high-order conforming Galerkin spatial discretizations and arbitrarily high-order discontinuous Galerkin temporal discretizations. Using equilibrated

Local Projection-Based Stabilized Mixed Finite Element Methods for Kirchhoff Plate Bending Problems

Abstract and Applied Analysis, 2013
Based on stress-deflection variational formulation, we propose a family of local projection-based stabilized mixed finite element methods for Kirchhoff plate bending problems.
