Wavelets and Fast Numerical Algorithms

, 1993
Wavelet based algorithms in numerical analysis are similar to other transform methods in that vectors and operators are expanded into a basis and the computations take place in this new system of coordinates.

Static stability of higher order functionally graded beam under variable axial load

Alexandria Engineering Journal, 2020
This article investigates effects of axial load distribution on buckling loads and their modes of functionally graded (FG) beams including a shear effect for the first time, since all previous studies focused on constant axial load.

Application of generalized differential quadrature method to nonlinear bending analysis of a single SWCNT over a bundle of nanotubes

Archives of Mechanics, 2012
The deformation of an individual single walled carbon nanotube (SWCNT) over a bundle of nanotubes has been studied using the generalized differential quadrature (GDQ) method.

Quadrature domains and kernel function zipping

, 2004
It is proved that quadrature domains are ubiquitous in a very strong sense in the realm of smoothly bounded multiply connected domains in the plane. In fact, they are so dense that one might as well assume that any given smooth domain one is dealing with

Re-Investigation of Generalized Integrator Based Filters From a First-Order-System Perspective

IEEE Access, 2016
The generalized integrator (GI)-based filters can be categorized into two types: one is related to quadrature signal generator (QSG), and the other is related to sequence filter (SF).

Generalized intelligent states of the su(N) algebra

, 2004
Schr\" odinger-Robertson uncertainty relation is minimized for the quadrature components of Weyl generators of the algebra $su(N)$. This is done by determining explicit Fock-Bargamann representation of the $su(N)$ coherent states and the differential ...

Size‐dependent static bending of anisotropic rectangular nanoplates with cubic crystal structures

Micro & Nano Letters, 2021
Here, size‐dependent static bending of anisotropic rectangular nanoplates is investigated based on surface elasticity theory. The governing equations of the nanoplate are derived considering the most common boundary conditions in MEMS/NEMS.

A Robust and Versatile Numerical Framework for Modeling Complex Fractional Phenomena: Applications to Riccati and Lorenz Systems

Fractal and Fractional
The fractional differential quadrature method (FDQM) with generalized Caputo derivatives is used in this paper to show a new numerical way to solve fractional Riccati equations and fractional Lorenz systems.

Defect correction from a galerkin viewpoint [PDF]

, 1985
We consider the numerical solution of systems of nonlinear two point boundary value problems by Galerkin's method. An initial solution is computed with piecewise linear approximating functions and this is then improved by using higher—order piecewise ...

Optimal prediction for moment models: Crescendo diffusion and reordered equations

, 2009
A direct numerical solution of the radiative transfer equation or any kinetic equation is typically expensive, since the radiative intensity depends on time, space and direction.
