Some researches on trivariate Lagrange interpolation [PDF]

, 2006
In this paper, in order to go a step further research on the problem of trivariate Lagrange interpolation, we pose the concepts of sufficient intersection of algebraic surfaces and Lagrange interpolation along a space algebraic curve, and extend Cayley ...

Immersed Boundary Projection Method for Boundaries With Slip Velocities

International Journal for Numerical Methods in Fluids, EarlyView.
A formulation of the immersed boundary method for incompressible flow over arbitrarily‐shaped bodies with surface slip described by the Navier boundary condition is presented. The wall slip velocity and the boundary force are determined implicitly through a projection to satisfy both the boundary condition and the divergence‐free condition of the ...

Counterexample-Guided Polynomial Loop Invariant Generation by Lagrange Interpolation [PDF]

International Conference on Computer Aided Verification, 2015
We apply multivariate Lagrange interpolation to synthesizing polynomial quantitative loop invariants for probabilistic programs. We reduce the computation of a quantitative loop invariant to solving constraints over program variables and unknown ...

Rainfall‐Induced Physical Crusting Is Associated With Near‐Surface Structural Degradation and Strain Localization During Drying in Loess Soil

Land Degradation &Development, EarlyView.
ABSTRACT Rainfall‐induced physical crusting is associated with degradation of near‐surface soil structure, but its pore‐scale structural and mechanical evolution during drying remains poorly resolved. We combined time‐resolved X‐ray computed tomography (XCT), digital volume correlation (DVC), and surface‐aligned stratification to track pore ...

Validation of Acoustic Emission Tomography Using Lagrange Interpolation in a Defective Concrete Specimen

Applied Sciences
Acoustic Emission tomography (AET) has the potential to visualize damage in existing structures, contributing to structural health monitoring. Further, AET requires only the arrival times of elastic waves at sensors to identify velocity distributions, as

Lagrange interpolation at Pollaczek-Laguerre zeros on the real semiaxis

Journal of Approximation Theory, 2019
In order to approximate functions defined on the real semiaxis, which can grow exponentially both at 0 and at + ∞ , we introduce a suitable Lagrange operator based on the zeros of orthogonal polynomials with respect to the weight w ( x ) = x γ e − x − α −

A highly accurate numerical method for solving boundary value problem of generalized Bagley‐Torvik equation

Mathematical Methods in the Applied Sciences, EarlyView.
A highly accurate numerical method is given for the solution of boundary value problem of generalized Bagley‐Torvik (BgT) equation with Caputo derivative of order 0<β<2$$ 0<\beta <2 $$ by using the collocation‐shooting method (C‐SM). The collocation solution is constructed in the space Sm+1(1)$$ {S}_{m+1}^{(1)} $$ as piecewise polynomials of degree at ...

Contributions to polynomial interpolation in one and several variables [PDF]

, 2011
Cette thèse traite de l'interpolation polynomiale des fonctions d'une ou plusieurs variables. Nous nous intéresserons principalement à l'interpolation de Lagrange mais un de nos travaux concerne les interpolations de Kergin et d'Hakopian.

The Combined Effects of Variable Viscosity and Thermal Conductivity of An Unsteady Casson Fluid Flow Along a Vertical Porous Channel With Convective Cooling Walls, Using the Bivariate Spectral Local Linearization Method

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This study examines the combined impact of different thermal conductivity and viscosity on unsteady non‐Newtonian Casson fluid flow of incompressible, electrical conductivity in a porous vertical channel with convective cooling walls, uniform magnetic field, and constant pressure gradient.
