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

arXiv, 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.

Estabelecimento do Conceito de Temperatura como uma grandeza derivada da Energia e da Entropia [PDF]

arXiv, 2002
Temperature is introduced as a derived concept from energy and entropy. We consider two sub-systems in equilibrium for several configurations. The equality of temperature of the sub-systems is obtained from the equilibrium condition. The isothermal transformation is defined for several configurations and from this definition we obtain the Clausius ...

The end of the Galactic spectrum [PDF]

arXiv, 2007
We use a diffusion galactic model to analyze the end of the Galactic cosmic ray spectrum and its mixing with the extragalactic cosmic ray flux. We analyze the transition between Galactic and extragalactic components using two different extragalactic models.

Modelagem de uma turbina radial para o ciclo de Rankine orgânico pelo método da linha média

CQD Revista Eletrônica Paulista de Matemática, 2017
A procura por novas fontes de energia útil tem suscitado o uso de fontes de baixo potencial térmico, como solar, geotérmica e térmica residual dos processos industriais. Nesse contexto, o uso de sistemas de geração de energia elétrica operando segundo o

Galactic neutrino background from cosmic ray interaction with the ISM content [PDF]

arXiv, 2007
We use a diffusive model for the propagation of Galactic cosmic rays to estimate the charged pion production in interactions with protons of the interstellar medium. Cosmic ray nuclei from proton to iron are considered and the corresponding contribution to the neutrino secondary flux produced as a result of spallation is also estimated.
