Neste trabalho, nós estudamos alguns problemas teóricos na teoria de corpos finitos e que são de interesse para várias aplicações, bem como em teoria de códigos, criptografia e áreas relacionadas. Em particular, nós estudamos ...

Strong couplings between the mechanical, electric, magnetic, fluidic and thermal fields exist in the behaviour laws describing microsystems. Also, due to the large surface/volume ratio, surface forces such as the electrostatic ...

This paper presents a methodology to evaluate the technical state of a Francis turbine by shaft rotor dynamic simulation. There are several rotor dynamic criteria that define the technical state of a turbo-machine. To feed ...

The conditions for the operation of railway systems are closely related to the increase of the commercial demand; as a consequence, the performance of the structural elements of railways changes. The present paper focuses ...

This work investigates the use of dynamical decoupling to shield quantum discord from errors introduced by the environment. Specifically, a two-qubit system interacting with independent baths of bosons is considered. The ...

This work aims to analyze the heat transfer in concrete structures. It is estimated thataround R$ 750M is lost annually due to fires involving concrete structures in Brazil.The main goal of the present work is perform the ...

In this paper, we propose a method to describe the many-body problem of electrons in honeycomb materials via the introduction of random fields which are coupled to the electrons and have a Gaussian distribution. From a ...
