Parallel Performance Studies for an Elliptic Test problem on the Cluster maya 2013; Using 1-D and 2-D domain subdivisions
(2014)One of the most important aspects of parallel computing is the communication between processes since it has tremendous impact on overall performance of this method of computing. Consequently, it is important to implement ... -
A Parallel Performance Study of the High-order Compact Direct Flux Reconstruction Method for Conservation Laws on Maya Cluster
(2017)The compact direct flux reconstruction method (CDFR) for conservation laws utilizes techniques from compact finite difference methods to directly approximate spatial derivatives of fluxes within standard elements. The CDFR ... -
A Preconditioned Flux Reconstruction/Correction Procedure via Reconstruction Formulation for Unsteady Low Mach Number Flows on Dynamic Unstructured Meshes
(AIAA SciTech Forum, 2017)Preconditioning methods can signicantly decrease the condition number of the linear system resulted from the discretization of compressible Navier-Stokes equations at low Mach numbers by replacing the physical acoustic ... -
Selection of optimal bands for developing multispectral system for inspecting apples for defects
(SPIE, 2019-04-30)Hyperspectral image technology is a powerful tool, but oftentimes the data dimension of hyperspectral images must be reduced for practical purposes, depending on the target and environment. For detecting defects on a variety ... -
Selection of Optimal Hyperspectral Wavebands for Detection of Discolored, Diseased Rice Seeds
(MDPI, 2019-03-12)The inspection of rice grain that may be infected by seedborne disease is important for ensuring uniform plant stands in production fields as well as preventing proliferation of some seedborne diseases. The goal of this ... -
Simulation of multi-pulse coaxial helicity injection in the Sustained Spheromak Physics Experiment
(AIP Publishing, 2017)Nonlinear, numerical computation with the NIMROD code is used to explore magnetic self-organization during multi-pulse coaxial helicity injection in the Sustained Spheromak Physics eXperiment. We describe multiple distinct ... -
Stress concentration around a rectangular cuboid hole in a three-dimensional elastic body under tension loading
(Springer, 2018-05-29)Stress concentration caused by holes can be investigated by numerical and analytical methods. Current analytical methods can only solve two-dimensional problems. This paper proposes an analytical study on a three-dimensional ... -
A Theoretical Method to determine unstressed off-rate from multiple bond force spectroscopy
(Elsevier B.V, 2012-06-15)Using dynamic force spectroscopy to measure the kinetic off-rates of intermolecular bonds currently requires the isolation of single molecules. This requirement arises in part because no tractable analytic method for ... -
Towards High-order Accurate Numerical Simulation of Unsteady Flow Physics over Domains with Large Deformation
(AIAA, 2019)This paper presents the development of a high-order flux reconstruction (FR) formulation for unsteady flow simulation with dynamic grid algorithms. Specifically, the high-order FR formulation for the Navier-Stokes equations ... -
Understanding Unsteady Flow Physics of Two Types of Vertical Axis Wind Turbines with a Fluid-Structure Interaction Approach
(AIAA SciTech Forum, 2017)Unsteady flow physics of two types of vertical axis wind turbines (VAWTs), namely, a modified Savonius turbine and a hybrid Darrieus-modified-Savonius (HDMS) turbine, are numerically studied using a fluid-structure interaction ...
