Registro de imágenes de teledetección espacial
(2014)
El registro de imágenes se ha transformado en una de los procesos de mayor interés e importancia en el procesamiento de las mismas. Podemos observar que gran parte del registro, se sigue realizando de manera manual, lo ...
The cohomology of filiform Lie algebras of maximal rank
(2014)
We describe the structure of the cohomology of the filiform Lie algebras and as a module over their (2-dimensional) torus of derivations. Our approach relies on the fact that both filiform algebras have an ideal of codimension ...
On homogeneous Ricci solitons
(2014)
We study the evolution of homogeneous Ricci solitons under the bracket flow, a dynamical system on the space Hq,n ⊂ Λ2g∗ ⊗ g of all homogeneous spaces of dimension n with a q-dimensional isotropy, which is equivalent to ...
Inequality between size and angular momentum for bodies
(2014-01-31)
A universal inequality that bounds the angular momentum of a body by the square of its size is presented
and heuristic physical arguments are given to support it. We prove a version of this inequality, as
consequence of ...
Estudio teórico de la estabilidad de flavinas sobre superficies de Ag(111)
(Universidad Nacional del Sur, 2014)
Recientemente se estudió mediante técnicas electroquímicas y ópticas no lineales la adsorción de flavinas sobre superficies monocristalinas de Ag(111). Las flavinas presentan estructura ordenadas, las cuales, en algunos ...
On the evolution of the momentarily static radiation free data in the Apostolatos - Thorne cylindrical shell model
(2014-02-24)
In this paper we study the evolution of the 'Momentarily Static and Radiation Free' (MSRF) initial data for the Apostolatos–Thorne cylindrical shell model. After briefly reviewing the equations of motion, the definition ...
Permutation entropy applied to the characterization of the clinical evolution of epileptic patients under pharmacological treatment
(2014)
Different techniques originated in information theory and tools from nonlinear systems theory have been applied to the analysis of electro-physiological time series. Several clinically relevant results have emerged from ...
Benchmarking y optimización de algoritmos criptográficos
(2014)
El presente trabajo presenta los resultados de la optimización de algoritmos criptográficos en procesadores que disponen de las nuevas instrucciones AES, desarrolladas por Intel. En particular se trabajó sobre AES-CPFB y ...
Invertible bimodule categories over the representation category of a Hopf algebra
(2014-02-12)
For any finite-dimensional Hopf algebra H we construct a group homomorphism
BiGal (H) → BrPic(Rep(H)), from the group of equivalence classes of H-biGalois
objects to the group of equivalence classes of invertible exact ...
PEF: Python Error Finder
(2014-12)
La verificación del correcto funcionamiento de los sistemas es uno de los aspectos más importante
del desarrollo de software, y a su vez, uno de los más costosos de llevar a cabo. El testing tradicional
y la verificación ...
