Focusing on Large Eddy Simulation (LES) in the scalar field, this work has threefoldachievement:The development, validation and application of a new anisotropy subgrid scale (SGS)model that is designed to better describe the behavior of SGS scalar flux transportIn the frame of LES, a new developed anisotropy model is proposed and implemented.Unlike the isotropic SGS scalar f...

This paper describes the field tests of a simulation based game aiming at raising awareness and creating a deeper understanding of the dynamics of the comprehensive approach (CA). The setting of this game is that of a failed state where an UN intervention takes place after massive conflict that requires a CA to stabilize the situation. That is, the civil and military actors need to collaborate ...

An efficient computational scheme based on the first-principles pseudopotential method is proposed for the electron emission from nanostructures under an applied electric field. The emission rate of the electron through the potential barrier is calculated by integrating the time-dependent Schrödinger equation for the states residing initially inside the emitter. Our approach takes into account ...

The field is expanded in a wavelet series and the wavelet coefficients are varied in a simulation of the 2D φ 4 field theory. The drastically reduced autocorrelations result in a substantial decrease of computing requirements, compared to those in local Metropolis simulations. The improvement is shown to be the result of an additional freedom in the choice of the allowed range of change at the ...

Ultrasim is an interactive, menu-oriented simulator for finding the sound field from transducers. It is a tool for design of transducer arrays and transducer geometry, and will increase the user’s understanding of acoustic wave propagation. The simulator has primarily been developed for medical ultrasound, but has also been used for sonar analysis and non-destructive testing. The simulator has ...

We review a family of local algorithms that permit the simulation of charged particles with purely local dynamics. Molecular dynamics formulations lead to discretizations similar to those of “particle in cell” methods in plasma physics. We show how to formulate a local Monte-Carlo algorithm in the presence of the long ranged Coulomb interaction. We compare the efficiencies of our molecular dyna...

This work represents a literature review of the current state of simulation in adult education. The use of simulation and games in adult education has a considerable history. They have played a supporting role in the more objectivist approaches to knowledge that has pervaded adult education for the last two centuries. They do so by representing a systematic illustration of a universal truth wit...

This paper describes a novel approach, called Force Field Simulation, to multi robot mapping that works under the constraints given in autonomous search and rescue robotics. Extremely poor prealignment, lack of landmarks, and minimal overlap between scans are the main challenges. The presented algorithm solves the alignment problem of such laser scans utilizing a gradient descent approach motiv...
