La cuestión filosófica de la expansión del universo
(Pontificia Universidad Católica Argentina. Facultad de Filosofía y Letras, 2006)
Resumen: En la primera mitad del siglo xx, diversos astrónomos y cosmólogos
propusieron la teoría de la expansión uniforme del universo. Las investigaciones debidas a Friedmann, Hubble, Humanson, Lemaltre y otros
autores ...
Synthesis Of Spatio-temporal Models By The Evolution Of Non-uniform Cellular Automata
(Springer Verlag, 2009)
The thermohydrodynamical picture of a charged Brownian particle
(Sociedad Mexicana de Fisica, 2002-12-01)
We study a charged Brownian gas with a non uniform bath temperature, and present a thermohydrodynamical picture. Expansion on the collision time probes the validity of the local equilibrium approach and the relevant ...

Normality in non-integer bases and polynomial time randomness
(Academic Press Inc Elsevier Science, 2015-04)
It is known that if x ∈ [0, 1] is polynomial time random (i.e. no polynomial time computable martingale succeeds on the binary fractional expansion of x) then x is normal in any integer base greater than one. We show that ...
"Afundamentos de tensão no contexto da expansão dos sistemas elétricos: proposta de índices considerando dados do sistema de detecção de descargas atmosféricas"
(Universidade Federal de Minas GeraisUFMG, 2009-02-20)
The impact of voltage sags to power utilities and consumers has been remarking this event as a relevant phenomenon to address in power system studies. It is considered one of the most frequent sources of power-supply ...
Análise de uma metaestrutura elástica com sistemas localmente ressonantes não uniformes
(Universidade Estadual Paulista (Unesp), 2021-08-02)
This work is based on the analysis of an elastic metamaterial with locally resonant systems, which consists of a cantilever beam with allocation of five equidistant resonators (spring-mass systems). Although typically the ...
First-passage times for pattern formation in nonlocal partial differential equations
(American Physical Society, 2015-10)
We describe the lifetimes associated with the stochastic evolution from an unstable uniform state to a patterned one when the time evolution of the field is controlled by a nonlocal Fisher equation. A small noise is added ...
Orthogonal Polynomial Projection Error Measured in Sobolev Norms in the Unit Disk
(2017)
We study approximation properties of weighted -orthogonal projectors onto the space of polynomials of degree less than or equal to N on the unit disk where the weight is of the generalized Gegenbauer form . The approximation ...
