Omnetpy: integración del lenguaje Python en el entorno de simulación OMNeT++
(2022-03)En este trabajo elaboramos un paquete que permite el desarrollo de módulos Python para la herramienta de simulación de redes OMNeT++. También analizamos el estado del arte en el uso de Python para la simulación de redes. ... -
On a mathematical theory of complex systems on networs with application to opinion formation
(2014)This paper presents a development of the so-called kinetic theory for active particles to the modeling of living, hence complex, systems localized in networks. The overall system is viewed as a network of interacting nodes, ... -
On Dirichlet problems with singular nonlinearity of indefinite sign
(2015)Let Ω be a smooth bounded domain in RN , N ≥ 1, let K, M be two nonnegative functions and let α, γ > 0. We study existence and nonexistence of positive solutions for singular problems of the form −Δu = K(x)u−α − λM (x)u−γ ... -
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 ... -
On Lifetimes of Dusty Debris Disks around A-type Stars

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), ... -
On stochastic spatial patterns and neuronal polarity
(2014)Polarization refers to asymmetric changes in cellular organization that occur in response to external or internal signals. Although neurons can spontaneously establish and maintain asymmetric distributions of signalling ... -
On structural completeness versus almost structural completeness problem : a discriminator varieties case study
(2015)We study the following problem: determine which almost structurally complete quasivarieties are structurally complete. We propose a general solution to this problem and then a solution in the semisimple case. As a consequence, ... -
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 ... -
On the linear stability of the extreme Kerr black hole under axially symmetric perturbations
(2014)We prove that for axially symmetric linear gravitational perturbations of the extreme Kerr black hole, there exists a positive definite and conserved energy. This provides a basic criteria for linear stability in axial ... -
On the nature of defects in liquid-phase exfoliated graphene
(2014)Liquid-phase exfoliation is one of the most promising routes for large-scale production of multilayer graphene dispersions. These dispersions, which may be used in coatings, composites, or paints, are believed to contain ... -
On the redshift of the gamma-ray blazar PKS 0447-439: Optical spectroscopy using Gemini observations with high S/N ratio
(Centro Brasileiro de Pesquisas Físicas (CBPF), 2013) -
On the relationship between trade agreements and institutional and political factors
(2015-11)The present paper focuses on the importance that institutional and political factors play on Latin American (LA) economic integration, where there is an increasing heterogeneity among countries. By focusing on both a ... -
On the robustness of standalone referring expression generation algorithms using RDF data
(2016)A sub-task of Natural Language Generation (NLG) is the generation of referring expressions (REG). REG algorithms are expected to select attributes that unambiguously identify an entity with respect to a set of distractors. ... -
On the theorem of the primitive element with applications to the representation theory of associative and Lie algebras
(2014)We describe all finite dimensional uniserial representations of a commutative associative (resp. abelian Lie) algebra over a perfect (resp. sufficiently large perfect) field. In the Lie case the size of the field depends ... -
On – Off : activación de sectores pericentrales, detención de crecimiento periurbano
(2021)Se observa que el crecimiento de la mancha urbana de Córdoba hacia los sectores peri-urbanos y la baja densidad de sus sectores peri-centrales. Denota una falla en el comportamiento urbano, generada por el problema del ... -
Onda Minera. La radio escolar: ¿por qué y para qué? Experiencias de trabajo en la Escuela de Minería de José de la Quintana
(2017)Este Trabajo Final de Licenciatura es el resultado de una Investigación en el campo realizada en una escuela secundaria de José de la Quintana (Provincia de Córdoba), entre los meses de junio y noviembre del año 2016. Ésta ... -
Ondas mecánicas
(2021-03)El presente informe da cuenta del avance que se dio en la materia Metodología, Observaciones y Prácticas de la Enseñanza correspondiente al cuarto año de la carrera de Profesorado de Física en la Facultad de Matemática, ... -
One-dimensional singular problems involving the p-Laplacian and nonlinearities indefinite in sign
(2016)Let Ω be a bounded open interval, let p > 1 and γ >, and let m : Ω → ℝ be a function that may change sign in Ω. In this article we study the existence and nonexistence of positive solutions for one-dimensional singular ... -
One-hour social and reproductive behavioral time series of Japanese quail in diverse social environments
(2022)We favor the conformation of divergent social environments by using the preselecting animals based on a combination of the 4 behavioral tests described in the project description. Social groups composed of three adult ...
