Mixing Bandt-Pompe and Lempel-Ziv approaches : another way to analyze the complexity of continuous-state sequences
(2014)
In this paper, we propose to mix the approach underlying Bandt-Pompe permutation entropy
with Lempel-Ziv complexity, to design what we call Lempel-Ziv permutation complexity. The principle
consists of two steps: (i) ...
Superficies isoperimétricas estables en Kerr y flujo de curvatura media
(2014-09-12)
Se estudia la evolución de hipersuperficies en datos iniciales de la ecuación de Einstein. Por medio de una ecuación de flujo que involucra principalmente la curvatura media de la hipersuperficie. Se obtiene la evolución ...
Lógicas modales con operadores de cambio de accesibilidad
(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, ...
Modelado matemático de la interacción parásito-sistema inmune durante la enfermedad de Chagas
(2014-12)
En este trabajo se extiende un modelo matemático que describe la interacción competitiva del parásito Tripanosoma cruzi (agente causante de la enfermedad de Chagas) y el sistema inmune de su mamífero vertebrado hospedador ...
Simetrías en razonamiento automático : el caso de las lógicas modales y satisfacibilidad módulo teorías
(2014-03)
En esta tesis investigamos el uso de simetrías en el contexto de lógicas modales y de satisfacibilidad módulo teorías (SMT). Desarrollamos el marco teórico para utilizar las simetrías de
una fórmula modal utilizando el ...
A multipurpose experimental facility for advanced X-ray Spectrometry applications
(2014)
Motivation, Ultra High Vacuum Chamber (UHVC) project: To support/enhance the training of scientists/engineers from developing countries in the operation of synchrotron radiation instrumentation; To provide beam time access ...
Multisolitons with vector mesons on the two-sphere
(2014)
Recent studies have suggested a strong connection between the static solutions of the 3D Skyrme model and those corresponding to its low-dimensional analog (baby-Skyrme model) on a two-sphere. We have found almost identical ...
Spherical functions of fundamental K-types associated with the n-dimensional sphere
(2014)
In this paper, we describe the irreducible spherical functions of fundamental K-types associated with the pair (G, K) = (SO(n + 1), SO(n)) in terms of matrix hypergeometric functions. The output of this description is that ...
Nonmodal linear stability of the Schwarzschild black hole
(2014)
A proof is given that the space L of solutions of the linearized vacuum Einstein equation around a Schwarzschild black hole is parametrized by two scalar fields, which are gauge invariant combinations of perturbed algebraic ...
On nonsingular two-step nilpotent Lie algebras
(2014)
A 2-step nilpotent Lie algebra n is called non-singular if ad X : n → [n, n] is onto for any X /∈ [n, n]. We explore non-singular algebras in several directions, including the classification problem (isomorphism invariants), ...
