Entropy production in a heat conduction problem Produção de entropia e o problema da condução do calor

Heat conduction along an isolated bar placed between two reservoirs at different temperatures is studied. The entropy production is considered in detail with two different approaches. In the first one, the whole system (the bar and the two reservoirs) is analysed in the steady state with the help of standard thermodynamics. In the second one, the bar is divided into n cells and a simple finite ...

Algoritmos para o problema do subgrafo acíclico máximo sob restrições disjuntivas

In this work we tackle the Maximum Acyclic Subgraph problem under Negative Disjunctive Constraints (MASNDC) and the Maximum Acyclic Subgraph problem under Positive Disjunctive Constraints (MASPDC), both belonging to the NP Hard class. Disjunctive constraints can be negative, in which a certain pair of entities cannot be contained simultaneously in a feasible solution; or positive in that, given...

O Problema do Subgrupo Oculto em uma Classe de Produto Semidireto de Grupos

We present an efficient quantum algorithm for the hidden subgroup problem (HSP) on the semidirect product of cyclic groups Zpr oφ Zps , where p is any odd prime number and r and s are any positives integers such that r ≥ 2s. This quantum algorithm is exponentially more efficient than any classical algorithm for the same purpose. Resumo. Neste trabalho, apresentamos um algoritmo quântico eficien...

Neuropsicologia E O Paradigma Do Cérebro Social

The aim of this review is to discuss the social nature of the brain and to argue about neuropsychology's potentiality to understand this phenomenon. Weconsider that the brain has a social nature, that is comprised of both biological and environmental dimensions,both relevant to the subject. Also, we introduce the notion of plastic brain and neuronal plasticity. We also discuss new scientific de...
