Relación de magnitud de coda para El oriente venezolano
(Universidad de Oriente, 2010)
On the stability of certain perturbed systems of differential equations and the relationship with the magnitude of the perturbationSobre la estabilidad de ciertos sistemas perturbados de ecuaciones diferenciales y sus relaciones con la magnitud de la perturbación
(2010-04-16)
In this work we consider a class of polytopes of third order squarematrices, studied early. We obtain a condition to guarantee Hurwitzstability of each of elements of the polytope. This condition is moresimples than one ...
Completitud del catálogo de la red sismológica nacional y distribución espacio-temporal de la sismicidad de Costa Rica (1975-2014)
(2017)
En este artículo se evalúa la estabilidad de la tasa media de ocurrencia de sismos y la distribución temporal de la sismicidad en Costa Rica a partir del método de Stepp, con el fin de determinar la magnitud de completitud ...
Algunas observaciones sobre la noción kantiana de simultaneidad
(Universidad de Santiago de Compostela. Facultad de Filosofía, 2014-07)
Se comparan los análisis sobre la simultaneidad que Kant efectúa en la “Tercera Analogía de la Experiencia” (KrV) y en la “Analítica de lo sublime” (KU) con el fin de comprender las diferencias entre ambos enfoques. Se ...
Blue upconversion enhancement by a factor of 200 in Tm 3+-doped tellurite glass by codoping with Nd 3+ ions
(2002-11-15)
We investigated near-infrared-to-blue upconversion from thulium (Tm 3+) doped in tellurite glasses upon continuous wave excitation near 800 nm. We observed an enhancement of over two orders of magnitude of the upconverted ...
A new empirical relation between surface wave magnitude and rupture length for turkey earthquakes
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2014-12-11)
Many practical problems encountered in quantitative oriented disciplines entail finding the best approximate solution to an over determined system of linear equations. In this study, it is investigated the usage of different ...
The Evolution of Modularity in the Mammalian Skull I: Morphological Integration Patterns and Magnitudes
(SPRINGER, 2009)
Morphological integration refers to the modular structuring of inter-trait relationships in an organism, which could bias the direction and rate of morphological change, either constraining or facilitating evolution along ...
A relação entre o social e o natural nas abordagens de hazards e de desastres
(ANPPAS - Revista Ambiente e Sociedade, 2001-12-01)
O artigo aborda as teorias dos Hazards e dos Desastres. Nos últimos anos estas duas tradições teóricas têm recebido novos impulsos pela renovação de seus marcos de referência conceitual. Construídas em torno de uma longa ...
Higher-order theories from the minimal length
(2016-06-10)
We show that the introduction of a minimal length in the context of noncommutative space-time gives rise (after some considerations) to higher-order theories. We then explicitly demonstrate how these higher-derivative ...
