Ocean wave simulation has a wide range of applications in movies, video games and training systems. Wind force is the main energy resource for generating ocean waves, which are the result of the interaction between wind and the ocean surface. While numerous methods to handle simulating oceans and other fluid phenomena have undergone rapid development during the past years in the field of comput...

Amplitude modulation and packet formation of Langmuir waves are commonly observed during a nonlinear interaction between electron beams and plasmas. In this paper, we briefly review the history of Langmuir wave packets as developed by recent spacecraft observations and computer simulations. New one-dimensional electrostatic Vlasov simulations are performed to study their formation processes. It...

Whistler mode chorus emissions with a characteristic frequency chirp are important magnetospheric waves, responsible for the acceleration of outer radiation belt electrons to relativistic energies and also for the scattering loss of these electrons into the atmosphere. A laboratory experiment (Van Compernolle et al 2015 Phys. Rev. Lett. 114 245002, An et al 2016 Geophys. Res. Lett.) in the larg...

Abstract A Monte Carlo simulation of chemotactic bacteria is developed on the basis of the kinetic modeling, i.e., the Boltzmann transport equation, and is applied to a one-dimensional traveling population wave in a microchannel. In this simulation, the Monte Carlo method, which calculates the run-and-tumble motions of bacteria, is coupled with a finite volume method to calculate the macroscopi...

The time histories of stochastic ocean wave-related processes are simulated by means of computatlonally efficient parametric models The parametric models utdlzed here include the autoregresslve and moving averages (ARMA) algorithms for the simulation of wave height fluctuations, discrete convolution models for linear transformations of given time histories, discrete differentlatmn models for ob...

New emerging multimedia standards, like the MPEG-4 standard allow the creation of virtual or synthetic acoustical environments. To auralize an environment from its geometric description, simulation algorithms for acoustic wave propagation are required. The different methods used for computational modeling of room acoustics can be divided into three groups [1]: statistical models, ray-based mode...
