Relation-changing modal logics
(2014)
En esta tesis investigamos operadores modales dinámicos que pueden cambiar el modelo durante la evaluación de una fórmula. En particular, extendemos el lenguaje modal básico con modalidades que son capaces de invertir, ...
A high performance biometric system based on image morphological analysis
(2014)
At present, many of the algorithms used and proposed for digital imaging biometric systems are based on mathematical complex models, and this fact is directly related to the performance of any computer implementation of ...
Landau-Zener and Rabi oscillations in the spin-dependent conductance
(2014)
We describe the spin-dependent quantum conductance in a wire where a magnetic field is spatially modulated. The changes in direction and intensity of the magnetic field acts as a perturbation that mixes spin projections. ...
Considering correlation properties on statistical simulation of clutter
(2015)
Statistical properties of image data are of paramount importance in the design of pattern recognition technics and the interpretation of their outputs. Image simulation allows quantification of method?s error and accuracy. ...
d-Dimensional KPZ equation as a stochastic gradient flow in an evolving landscape : interpretation and time evolution of its generating functional
(2017)
The deterministic KPZ equation has been recently formulated as a gradient flow. Its non-equilibrium analog of a free energy—the “non-equilibrium potential” Φ[h], providing at each time the landscape where the stochastic ...
Structural and magnetic properties of nanocrystalline Bi1-xLaxFeO3 (0.0 ≤ x ≤ 0.4) synthesized by a mechanochemical route
(2017)
Bi1-xLaxFeO3 (0.0 ≤ x ≤ 0.4) powders were prepared by means of a solid acid-base reaction induced by mechanochemical energy. Bi, La and Fe chlorides were high-energy ball-milled with NaOH, yielding a mixture of Bi1-xLaxFeO3 ...
