We propose an experimental way to test theories concerning DNA evolution mechanisms, through computer simulations.

We propose the Langevin-type microscopic equations of motion for magnetic fluids. Magnetic fluids are modeled as an ensemble of interacting ferromagnetic nanoparticles suspended in a viscous fluid. The present model is described in terms of position vectors of nanoparticles and orientation...

We present a model equation that describes nucleation and growth of hemispherical nanoclusters or islands deposited on a substrate for the small surface coverage case. The model is formulated in terms of a set of rate equations for the island sizes, combined with the time-dependent behavior of...

Street demonstrations occur across the world. In Rio de Janeiro, in June/July 2013, they reach beyond one million people. A wrathful reader of O Globo, a leading newspaper in the same city, published a letter (Ferreira (2011)  [10]) where many social questions are stated and answered Yes or No....

In this article, we describe simulation-based decision support techniques for evaluation of operational plans within effects-based planning. Using a decision support tool, developers of operational plans are able to evaluate thousands of alternative plans against possible courses of events and...
