Journal of Marine Science and Engineering, 2022 Generally, wave energy resource assessment and characterization are performed based on an entire wave spectrum, ignoring the detailed energy features that belong to wave systems, i.e., wind waves and swells. In reality, the energy is separately possessed

On the Hughes model and numerical aspects [PDF]
2016 IEEE 55th Conference on Decision and Control (CDC), 2016 We study a crowd model proposed by R. Hughes and we describe a numerical approach to solve it. The Hughes model comprises a Fokker-Planck equation coupled with an eikonal equation with Dirichlet or Neumann data. First, we establish a priori estimates for the solutions. Second, we study radial solutions and identify a shock formation mechanism.

Tidal resonance in the Gulf of Thailand [PDF]
Ocean Science, 2019 The Gulf of Thailand is dominated by diurnal tides, which might be taken to indicate that the resonant frequency of the gulf is close to one cycle per day.

Resolving Gas Bubbles Ascending in Liquid Metal from Low-SNR Neutron Radiography Images
Applied Sciences, 2021 We demonstrate a new image processing methodology for resolving gas bubbles travelling through liquid metal from dynamic neutron radiography images with an intrinsically low signal-to-noise ratio.

Discrete element method and its application to the analysis of penetration into granular media
Journal of Civil Engineering and Management, 2004 Application of discrete element method (DEM) to keel penetration in granular media is investigated. The basic relations for viscoâ€elastic granular media composed of spherical particles are presented, together with 5th order Gear predictorâ€corrector ...

Journal of Civil Engineering and Management, 2000 For the numerical simulation of engineering problems, the finite element method (FEM) is among the most popular approaches. One of the main concerns in a finite element analysis is the adequacy of the finite element grid.
