Quasi-interpolants splines : exemples et applications [PDF]
ESAIM: Proceedings, 2007 A quasi-interpolant (abbr. QI) is an approximation operator obtained as a finite linear combination of basis functions with bounded support (B-splines). In addition, the coefficient of a B-spline is a linear functional (of differential, discrete or integral type) acting on the function to be approximated in a neighbourhood of the support of that B ...

Molecular Cross‐Linking of MXenes: Tunable Interfaces and Chemiresistive Sensing
Advanced Functional Materials, EarlyView.In this study, Ti3C2Tx MXenes are initially functionalized using oleylamine ligands to form stable dispersions in an organic solvent. Subsequently ligand exchange with α,ω‐diaminoalkanes enables cross‐linking, along with precise tuning of interfaces. This structural control translates into tunable charge transport and responsive VOC sensing, showing ...

Quasi-Interpolation in Shift Invariant Spaces
Journal of Mathematical Analysis and Applications, 2000 Let \(\phi:\mathbb{R}^s\to\mathbb{R}\) be a compactly supported function, and \(S(\phi)\) denote the linear span of \(\{\phi(\cdot -{\mathbf k}) :{\mathbf k}\in\mathbb{Z}^s\}\), \(s\in\mathbb{N}.\) The authors consider the problem of approximating a continuous function \(f : \mathbb{R}^s\to \mathbb{R}\) on compact subsets of \(\mathbb{R}^s\) from the ...

Advanced Functional Materials, EarlyView.Fe─NC porous oxygen reduction electrocatalysts are prepared employing a 2,4,6‐Triaminopyrimidine‐based porous organic polymer, a Mg2+ Lewis acid, and a low‐temperature cation exchange protocol. Using the polymer precursor achieves high pyrolysis yields and results in atomically dispersed FeNx sites. The resulting catalysts feature hierarchical porosity

Radau Quadrature for an Almost Quasi-Hermite-Fejer-Type Interpolation in Rational Spaces
International Journal of Analysis and Applications, 2021 In this paper, we have studied an almost quasi Hermite-Fejer-type interpolation in rational spaces. A Radau type quadrature formula has also been obtained for the same.

Finite element quasi-interpolation and best approximation [PDF]
, 2015 This paper introduces a quasi-interpolation operator for scalar- and vector-valued finite element spaces constructed on affine, shape-regular meshes with some continuity across mesh interfaces.This operator gives optimal estimates of the best ...

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics
Advanced Functional Materials, EarlyView.Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

On Multiscale Methods in Petrov-Galerkin formulation [PDF]
, 2014 In this work we investigate the advantages of multiscale methods in Petrov-Galerkin (PG) formulation in a general framework. The framework is based on a localized orthogonal decomposition of a high dimensional solution space into a low dimensional ...
