A linear CO chemistry parameterization in a chemistry-transport model: evaluation and application to data assimilation [PDF]

open access: yesAtmospheric Chemistry and Physics, 2010
This paper presents an evaluation of a new linear parameterization valid for the troposphere and the stratosphere, based on a first order approximation of the carbon monoxide (CO) continuity equation. This linear scheme (hereinafter noted LINCO) has been

Essential boundary conditions in meshfree methods via a modified variational principle. Applications to shell computations

open access: yesComputer Assisted Methods in Engineering and Science, 2022
It has been recognized by many authors that the enforcement of the essential boundary conditions is not an easy task, when it comes to moving least square (MLS)-based meshfree methods.

Modeling elastic wave propagation in fluid-filled boreholes drilled in nonhomogeneous media: BEM – MLPG versus BEM-FEM coupling [PDF]

open access: yes, 2017
The efficiency of two coupling formulations, the boundary element method (BEM)-meshless local Petrov–Galerkin (MLPG) versus the BEM-finite element method (FEM), used to simulate the elastic wave propagation in fluid-filled boreholes generated by a blast ...

Approximate ML Decoding of Short Convolutional Codes Over Phase Noise Channels [PDF]

open access: yesIEEE Communications Letters, 2020
We propose a decoding algorithm for tail-biting convolutional codes over phase noise channels. It can be seen as a reduced complexity approximation of maximum likelihood decoding. We target short blocks and extend the wrap-around Viterbi algorithm to trellises describing the random evolution of the phase impairment, for which we adopt two different ...

Element-Free Galerkin Scaled Boundary Method Based on Moving Kriging Interpolation for Steady Heat Conduction Analysis with Temperatures on Side-Faces

open access: yesShanghai Jiaotong Daxue xuebao, 2021
The element-free Galerkin scaled boundary method (EFG-SBM) based on moving Kriging (MK) interpolation is used to solve steady heat conduction problems with temperature loads on side-faces, in which the circumferential boundary is discretized based on MK ...
