Numerical simulation is the main method to solve turbulence problems. As one of the three methods which are commonly used in large-eddy simulation model (LES) is the most effective and promising research method. The basic idea of large-eddy simulation is

Transmission dynamics and optimal control of stage-structured HLB model
Citrus Huanglongbing (HLB) is one of severe quarantine diseases affecting citrus production both in abroad and domestic. Based on the mechanism and characteristics of citrus HLB transmission, we establish a vector-borne model with stage structure and ...

Numerical simulation of optimal transport paths [PDF]
This article provides numerical simulation of an optimal transport path from a single source to an atomic measure of equal total mass. We first construct an initial transport path, and then modify the path as much as possible by using both local and global minimization algorithms.

First-principle-like reinforcement learning of nonlinear numerical schemes for conservation laws [PDF]
In this study, we present a universal nonlinear numerical scheme design method enabled by multi-agent reinforcement learning (MARL). Different from contemporary supervised-learning-based and reinforcement-learning-based approaches, no reference data and special numerical treatments are used in the MARL-based method developed here; instead, a first ...

Investigation of 3D Patterns on EUV Masks by Means of Scatterometry and Comparison to Numerical Simulations [PDF]
EUV scatterometry is performed on 3D patterns on EUV lithography masks. Numerical simulations of the experimental setup are performed using a rigorous Maxwell solver. Mask geometry is determined by minimizing the difference between experimental results and numerical results for varied geometrical input parameters for the simulations.

Proper Selection of Obreshkov-Like Numerical Integrators Used as Numerical Differentiators for Power System Transient Simulation [PDF]
Obreshkov-like numerical integrators have been widely applied to power system transient simulation. Misuse of the numerical integrators as numerical differentiators may lead to numerical oscillation or bias. Criteria for Obreshkov-like numerical integrators to be used as numerical differentiators are proposed in this paper to avoid these misleading ...
