Spectral Domain Low- Coherence Interferometry for On-line Surface Inspection [PDF]
, 2013 We present an on-line surface measurement technique based on spectral domain low-coherence interferometry (SD-LCI), which can obtain a one dimensional surface profile with just one shot.

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2020 This research aims to develop a new ride comfort simulation technology for a three-axle heavy vehicle. To consider the elasticity of the frame, the finite element method (FEM) is used to analyze the free mode of the frame, and the elastic information of ...

Fourier Analysis of Stochastic Sampling Strategies for Assessing Bias and Variance in Integration [PDF]
, 2013 Each pixel in a photorealistic, computer generated picture is calculated by approximately integrating all the light arriving at the pixel, from the virtual scene. A common strategy to calculate these high-dimensional integrals is to average the estimates

A Fourth Order Energy Dissipative Scheme for a Traffic Flow Model
Mathematics, 2020 We propose, analyze and numerically validate a new energy dissipative scheme for the Ginzburg–Landau equation by using the invariant energy quadratization approach.

Computing Nearly Singular Solutions Using Pseudo-Spectral Methods [PDF]
, 2007 In this paper, we investigate the performance of pseudo-spectral methods in computing nearly singular solutions of fluid dynamics equations. We consider two different ways of removing the aliasing errors in a pseudo-spectral method.

Comparison of dealiasing schemes in large-eddy simulation of neutrally stratified atmospheric flows [PDF]
Geoscientific Model Development, 2018 Aliasing errors arise in the multiplication of partial sums, such as those encountered when numerically solving the Navier–Stokes equations, and can be detrimental to the accuracy of a numerical solution.

Modified Fourier expansions: theory, construction and applications
, 2010 Modified Fourier expansions present an alternative to more standard algorithms for the approximation of nonperiodic functions in bounded domains. This thesis addresses the theory of such expansions, their effective construction and computation, and ...

A Unifying Numerical Framework for the “Small-Slope” Based Core-Annular Flow Instability Models
Mathematics, 2020 The snap-off is an instability phenomenon that takes place during the immiscible two-phase flow in porous media due to competing forces acting on the fluid phases and at the interface between them.
