, 2017 In this article, we address adaptive methods for isogeometric analysis based on local refinement guided by recovery based a posteriori error estimates. Isogeometric analysis was introduced a decade ago and an impressive progress has been made related to ...

Top-down estimates of biomass burning emissions of black carbon in the Western United States [PDF]
Atmospheric Chemistry and Physics, 2014 We estimate biomass burning and anthropogenic emissions of black carbon (BC) in the western US for May–October 2006 by inverting surface BC concentrations from the Interagency Monitoring of PROtected Visual Environment (IMPROVE) network using a global ...

A Priori and a Posteriori Error Analysis for Generic Linear Elliptic Problems
Tikrit Journal of Pure Science, 2022 In this paper, a priori error analysis has been examined for the continuous Galerkin finite element method which is used for solving a generic scalar and a generic system of linear elliptic equations.

A Posteriori Probabilistic Bounds of Convex Scenario Programs with Validation Tests
, 2020 Scenario programs have established themselves as efficient tools towards decision-making under uncertainty. To assess the quality of scenario-based solutions a posteriori, validation tests based on Bernoulli trials have been widely adopted in practice ...

Should we use a simple or complex model for moisture recycling and atmospheric moisture tracking? [PDF]
Hydrology and Earth System Sciences, 2013 This paper compares state-of-the-art atmospheric moisture tracking models. Such models are typically used to study the water component of coupled land and atmosphere models, in particular quantifying moisture recycling and the source-sink relations ...

Adaptive discontinuous Galerkin approximations to fourth order parabolic problems [PDF]
, 2013 An adaptive algorithm, based on residual type a posteriori indicators of errors measured in $L^{\infty}(L^2)$ and $L^2(L^2)$ norms, for a numerical scheme consisting of implicit Euler method in time and discontinuous Galerkin method in space for linear ...

A posteriori subcell limiting of the discontinuous Galerkin finite element method for hyperbolic conservation laws [PDF]
Journal of Computational Physics, 2014 The purpose of this work is to propose a novel a posteriori finite volume subcell limiter technique for the Discontinuous Galerkin finite element method for nonlinear systems of hyperbolic conservation laws in multiple space dimensions that works well ...

Maximum a posteriori adaptation of network parameters in deep models [PDF]
Interspeech, 2015 We present a Bayesian approach to adapting parameters of a well-trained context-dependent, deep-neural-network, hidden Markov model (CD-DNN-HMM) to improve automatic speech recognition performance.

Modal Empiricism and Two-Dimensional Semantics [PDF]
, 2009 In the paper I argue that it follows from David Chalmers’ semantics and metaphysics concerning microphysical terms that microphysical identifications are strongly necessary.
