Influence of phase space localization on the energy diffusion in a quantum chaotic billiard [PDF]

open access: yes, 1998
The quantum dynamics of a chaotic billiard with moving boundary is considered in this work. We found a shape parameter Hamiltonian expansion which enables us to obtain the spectrum of the deformed billiard for deformations so large as the characteristic wave length.

Energia solar no tratamento de corante têxtil

open access: yesRevista Verde de Agroecologia e Desenvolvimento Sustentável, 2014
As indústrias utilizam a água em todo o seu processo, desperdiçando enormes volumes de água gerando efluentes com altos índices de produtos químicos, precisando de tratamento para ser reutilizado ou lançado no meio ambiente. Nesse contexto, o presente trabalho foi realizado no Laboratório de Engenharia Ambiental e de Qualidade na Universidade Federal ...

Asymptotic expansion for the models of nonlinear dispersive, dissipative, equations [PDF]

open access: yesarXiv, 2003
Considered herein are the family of nonlinear equations with both dispersive and dissipative homogeneous terms appended. Solutions of these equations that start with finite energia decay to zero as time goes to infinity. We present an asymptotic form which renders explicit the influence of the dissipative, dispersive and nonlinear effect in this decay.

Case study on economic return on investments for safety and emergency lighting in road tunnels [PDF]

open access: yes, 2015
While planning a double-hole road tunnel with a length higher than one km, it is important to pay attention to the safety factor if an accident occurs. If there is a power outage, in order to avoid critical situations that could jeopardize the safety of ...
