Proofs of the undecidability of stegananalysis techniques
(SpringerCH, 2020)
Steganalysis comprises a set of techniques that strive to find concealed information within diverse types of digital media. On the contrary, Steganography involves a group of methods that, by manipulation of a cover object, ...
Sistemas peculiares de galaxias :
(2009-03)
Se presenta un estudio estadístico sobre grupos compactos y fósiles identificados en simulaciones numéricas combinadas
con diferentes modelos semianalíticos de formación de galaxias. Los resultados fueron también confrontados ...
Iterative methods and their dynamics with applications: A contemporary study
Iterative processes are the tools used to generate sequences approximating solutions of equations describing real life problems. Intended for researchers in computational sciences and as a reference book for advanced ...
Interacciones Planeta-Disco : desarrollo y utilización de un código numérico
(2015)
La fuerza gravitatoria de un protoplaneta sumergido en un disco protoplanetario genera estructuras de densidad asimétricas que ejercen un torque neto sobre él. Este torque puede alterar de forma drástica la órbita del ...
Bayesian framework to quantify uncertainties in piezoelectric energy harvesters
(American Society of Mechanical Engineers (ASME), 2018)
The interest of this work is to describe a framework that allows the use of the well-known dynamic estimators in piezoelectric harvester (deterministic performance estimators) but taking into account the random error ...
Arquitectura y evolución de sistemas planetarios en resonancias de dos cuerpos
(2017-12)
En esta tesis se estudia de forma analítica y numérica el movimiento de una partícula de prueba perturbada en un potencial central. Se encuentran dos límites que permiten relacionar diferentes criterios de estabilidad, los ...
Sliding mode for detection and accommodation of computation time delay fault
(Elsevier B.V., 2009-10-01)
Computation time delay in digital control systems reduces its robustness as well as degrades its performance. In this paper, the computation time delay is assumed to be constant and smaller than the sampling time and is ...
Construction of a repertoire of analog form-finding techniques as a basis for computational morphological exploration in design and architecture
(SPRINGER, 2018-01-01)
The article describes the process of constructing a repertoire of analog form-finding techniques, which can be used in evolutionary computation to (i) compare the techniques among them and select the most suitable for a ...

Computation time delay in digital control systems reduces its robustness as well as degrades its performance. In this paper, the computation time delay is assumed to be constant and smaller than the sampling time and is ...
Controlling collapse in Bose-Einstein condensates by temporal modulation of the scattering length
(2003-01-01)
A study was conducted on the dynamics of 2D and 3D Bose-Einstein condensates in the case when the scattering length in the Gross-Pitaevskii (GP) equation which contains constant (dc) and time-variable (ac) parts. Using the ...
