From a systems theory of sociology to modeling the onset and evolution of criminality
(2015)
This paper proposes a systems theory approach to the modeling of onset and evolution of criminality in a territory. This approach aims at capturing the complexity features of social systems. Complexity is related to the ...
Study of the characteristic parameters of the normal voices of Argentinian speakers
(2014)
The voice laboratory permits to study the human voices using a method that is objective and noninvasive. In this work, we have studied the parameters of the human voice such as pitch, formant, jitter, shimmer and harmonic-noise ...
Normal holonomy of orbits and Veronese submanifolds
(2015)
It was conjectured, twenty years ago, the following result that would generalize the so-called rank rigidity theorem for homogeneous Euclidean submanifolds: let Mn, n ≥ 2, be a full and irreducible homogeneous submanifold ...
Playing against fair adversaries in stochastic games with total rewards
(2022)
We investigate zero-sum turn-based two-player stochastic games in which the objective of one player is to maximize the amount of rewards obtained during a play, while the other aims at minimizing it. We focus on games in ...
Search for gravitational radiation from intermediate mass black hole binaries in data from the second LIGO-Virgo joint science run
(2014)
This paper reports on an unmodeled, all-sky search for gravitational waves from merging intermediate mass black hole binaries (IMBHB). The search was performed on data from the second joint science run of the LIGO and Virgo ...
Tailoring optical fields emitted by nanometric sources
(2014)
In this work we study a simple way of controlling the emitted fields of sub-wavelength nanometric sources. The system studied consists of arrays of nanoparticles (NPs) embedded in optical active media. The key concept is ...
First-principles studies of lithium storage in reduced graphite oxide
(2014-09)
The present work performs a first-principles study of the lithiation of graphite oxides with low oxygencontent, which resemble reduced graphite oxide materials. The chemical nature of the Li structure formedis analysed, ...
Narrow-band search of continuous gravitational-wave signals from Crab and Vela pulsars in Virgo VSR4 data
(2015)
In this paper we present the results of a coherent narrow-band search for continuous gravitational-wave signals from the Crab and Vela pulsars conducted on Virgo VSR4 data. In order to take into account a possible small ...
Search for gravitational waves associated with gamma-ray bursts detected by the InterPlanetary Network
(2014)
We present the results of a search for gravitational waves associated with 223 γ-ray bursts (GRBs) detected by the InterPlanetary Network (IPN) in 2005-2010 during LIGO´s fifth and sixth science runs and Virgo´s first, ...
Adapting a Fourier pseudospectral method to Dirichlet boundary conditions for Rayleigh–Bénard convection
(2015)
We present the adaptation to non–free boundary conditions of a pseudospectral method based on the (complex) Fourier transform. The method is applied to the numerical integration of the Oberbeck–Boussinesq equations in a ...
