We study two models for competitive deposition and evaporation of particles from rough surfaces. The process of deposition is carried out for two models, one according to the ballistic deposition (BD) and the other according to the random deposition with a surface relaxation (RDSR). The process...

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....

Recent interest in the use of thermoelectric generators (TEGs) to recover waste heat in large-scale applications calls for precise simulation to appropriately design complicated and dynamic systems. The aim of this work is to develop a computer tool to accurately simulate the thermal and...
