Air pollution indicators in Brazil, Russia, India and China (BRIC) countries

Over the past several decades, the amount of attention given to various countries’ environmental impact has greatly increased. Brazil, Russia, India and China (BRIC) have been drawing special attention due to the pollution emissions released into the atmosphere by their increasing number of industries and their exaggerated consumption of products. This article aims to elucidate and analyze the evolution of some of...

Interval study of convergence in the solution of 1D Burgers by least squares finite element method (LSFEM) + Newton linearization

This paper aims to apply the least squares finite element method (LSFEM) in conjunction with the linearization technique known as Newton method. For this, the application chosen was the traditional 1D Burgers equation. From two numerical applications and an error analysis based on knowledge of the exact solution, will be possible to present convergence ranges for this proposal.   Key words: Least squares...
