Dust evolution simulation provides an important way to analyze the impact of dust on the environment. Since wind speed plays a key role in dust evolution, multi-scale simulation is applied to simulate the wind speed in order to improve the accuracy of wind speed simulation and reduce the amount of calculation. Through k-means clustering, the virtual campus can be divided by grids with different...

We present a triple-scale simulation of a molecular liquid, in which the atomistic, coarse-grained, and continuum descriptions of the liquid are concurrently coupled. The presented multiscale approach, which covers the length scales ranging from the micro- to macroscale, is a combination of two dual-scale models: a particle-based adaptive resolution scheme (AdResS), which couples the atomic and...

Active structures capable of responding to external stimulii represent the emerging frontier in structural design. Robust and real-time sensing, control, and actuation pose fundamental challenges that must be addressed in this context. As part of an ambitious project funded by the National Science Foundation, researchers at Purdue, Rice, Florida State, and the Catholic (Belgium) Universities ha...

This article provides a review of the computational nanomechanics, from the ab initio methods to classical molecular dynamics simulations, and multitemporal and spatial scale simulations. The recent improvements and developments are briefly discussed. Their applications in nanomechanics and nanotubes are also summarized.

Recently Rajasekaran and Ross [1] presented an algorithm that takes an expected 0(1) time to generate a nonuniform discrete random variate. In this paper we discuss how this algorithm can be employed in the efficient simulation of large-scale telephone networks. In a simulation based upon a standard event-list approach, the generation of a new event in the systems take 0(log n) time. With this ...

Large-scale hybrid networks that include wireless, wired, and satellite-based communications are becoming common in both military and commercial situations. This paper describes a scalable simulation environment that effectively utilizes parallel execution to reduce the simulation time of detailed high-fidelity models of large communication networks. The paper also presents a set of case studie...

Physically-driven methods of simulating fluid dynamics and frequencybased ocean surface synthesis methods are of long-standing interest for the field of computer graphics. However, they have been historically used separately or without any interaction between them. This thesis focuses on the possibility of combining the approaches into one adaptive solution by proposing methods for unified surf...

The ISO/IEC JPEG 2000 image coding standard is a family of source coding algorithms targeting high-resolution image communications. JPEG 2000 features highly scalable embedded coding features that allow one to interactively zoom out to reduced resolution thumbnails of enormous data sets or to zoom in on highly localized regions of interest with very economical communications and rendering requi...

In a previous work, we described a multi-scale protocol for the simulation of the conformation and dynamics of macromolecules that was applied to dendrimer molecules proving its predictive capability by comparison with experimental data. That scheme is now employed in order to predict conformational properties (radius of gyration) and overall hydrodynamic properties (translational diffusion and...
