Regular time-reproductive solutions for generalized Boussinesq model with Neumann boundary conditions for temperature
(2005)
The aim of this work is to prove existence of regular time reproductive solutions for a generalized Boussinesq model (with nonlinear diffusion for velocity and temperature). The main idea is to obtain higher regularity ...

Interaction potentials from periodic density-functional theory calculations: Molecular-dynamics simulations of Au clusters deposited on the TiN (001) surface
(AIP Publishing, 2005-12)
Molecular-dynamics simulations of gold particles deposited on a TiN 001 surface have been accounted for through classical pair potentials describing the atom force field. The interaction between Ti–N, Ti–Ti, N–N, Au–Au, ...

P Systems with Active Membranes, Without Polarizations and Without Dissolution: A Characterization of P
(Springer, 2005)
We study the computational efficiency of recognizer P systems with active membranes without polarizations and without dissolution. The main result of the paper is the following: the polynomial computational complexity ...

On Descriptive Complexity of P Systems
(Springer, 2005)
In this paper we address the problem of describing the complexity of the evolution of a P system. This issue is is specially hard in the case of P systems with active membranes, where the number of steps of a computation ...

Cálculo de los factores de intensificación de tensiones generalizados en uniones adhesivas metal-composite
(AEMAC (Asociación Española de Materiales Compuestos), 2005-06)
Las uniones adhesivas entre materiales metálicos y compuestos generan puntos críticos donde la geometría y/o las propiedades de los materiales cambian bruscamente. El estado tensional que predice la Teoría de la Elasticidad ...

Construcción del conocimiento y discurso educativo. Una aproximación al estudio del discurso de profesores y alumnos en la universidad
(Universidad del Rosario, 2005)
Este trabajo se encuentra claramente influenciado por los instrumentos conceptuales y metodológicos provenientes de la orientación de la construcción del conocimiento, la psicología discursiva, la teoría sociocultural y ...

A Study of the Robustness of the EGFR Signalling Cascade Using Continuous Membrane Systems
(Springer, 2005)
Many approaches to anticancer treatment have had a limited success. A fundamental hurdle to cancer therapy is the robustness of the signalling networks involved in tumourgenesis. The complexity of net- works of biological ...

Analytical approach to soliton ratchets in asymmetric potentials
(2005)
We use soliton perturbation theory and collective coordinate ansatz to investigate the mechanism of soliton ratchets in a driven and damped asymmetric double sine-Gordon equation. We show that, at the second order of the ...

Three-body continuum discretization in a basis of transformed harmonic oscillator states
(American Physical Society, 2005-01-01)
The inclusion of the continuum in the study of weakly bound three-body systems is discussed. A transformed harmonic oscillator basis is introduced to provide an appropriate discrete and finite basis for treating the ...
