(Universidad de Chile, 2012)Los solitones hidrodinámicos no propagativos son estructuras no lineales localizadas que aparecen en la superficie libre de un líquido cuasi-unidimensional que está sujeto a cierto tipo de inyección de energía, en particular, ...
-
(Universidad de Chile, 2020)La presente tesis se enmarca en la teoría de la optimización no suave y trata con problemas de la teoría de juegos. La tesis está dividida en cuatro partes, de las cuales en la primera se presenta la introducción, la ...

(MDPI, 2020)Microgrids have the potential to provide security and flexibility to power systems through the integration of a wide range of resources, including distributed energy storage, usually in the form of batteries. An aggregation ...
-
(London Mathematical Society, 2013)Existence of a positive, decaying radial solution to the problem Δu − u + up + λuq = 0 in RN, when λ > 0 and 1 < q < p < (N + 2)/(N − 2) has been known for a long time. For λ = 0, it is well known that this solution is ...
-
(Elsevier B.V., 2018)The problem of universality of critical exponents in complex networks is studied based on networks built from seismic data sets. Using two data sets corresponding to Chilean seismicity (northern zone, including the 2014 ...
-
(EDP Sciences, 2015)Several studies discussing imaging polarimetry observations of protoplanetary disks use the so-called radial Stokes parameters Q and U to discuss the results. This approach has the advantage of providing a direct measure ...
-
(SPRINGER, 2006-08)In this paper we proved a nonconvex separation property for general sets which coincides with the Hahn-Banach separation theorem when sets are convexes. Properties derived from the main result are used to compute the ...

-
(IOP Publishing, 2014)We study nonequilibrium quantum phase transitions in the XY spin 1/2 chain using the C* algebra. We show that the well-known quantum phase transition at a magnetic field of h = 1 also persists in the nonequilibrium setting ...
-
(American Physical Society, 2019)The rheology of semidilute bacterial suspensions is studied with the tools of kinetic theory, considering binary interactions, going beyond the ideal gas approximation. Two models for the interactions are considered, which ...
-
(JOHN WILEY & SONS INC, 2008-04-15)Syndiotactic polypropylenes and their copolymers with 1-olefins were synthesized using two metallocene/MAO catalytic systems, and the effect of the different microstructures on nonisothermal crystallization and subsequent ...
-
(Universidad de Chile, 2009)A escala diaria, el viento es el principal agente externo que entrega la energía suficiente a un lago estratificado para generar el movimiento del fluido y mezclar la columna de agua. Bajo este escenario, la dinámica ...
-
(Royal Soc., 2016)Using the classical theory of invariants for the specific class of graphene's symmetry, we constitutively characterize electro-magneto-mechanical interactions of graphene at continuum level. Graphene's energy depends on ...
-
(Wiley, 2017)Nonlinear finite element (FE) modeling has been widely used to investigate the effects of seismic isolation on the response of bridges to earthquakes. However, most FE models of seismic isolated bridges (SIB) have used ...
-
(Elsevier, 2017)In this paper, nonlinear finite element model updating (FEMU) is performed to study the prediction accuracy of a state-of-the-art finite element (FE) model of a seismic isolated bridge (SIB). The seismic isolator model ...
-
(SAGE, 2013)Two variational principles for nonlinear magnetoelastostatics are studied, considering a magnetosensitive body completely surrounded by free space extending to infinity. The functionals depend on the deformation function ...
-
(2010-04)We study the boundary stabilization of the wave equation by means of a linear or nonlinear Neumann feedback. The rotated multiplier method leads to new geometrical cases concerning the active part of the boundary where ...
-
(Universidad de Chile, 2013)En esta tesis definimos dos adaptaciones no-lineales del análisis de componentes principales, para el estudio de la variabilidad de datos conformados por medidas de probabilidad y por imágenes. En el Capitulo 2 introducimos ...
-
(GAUTHIER-VILLARS/EDITIONS ELSEVIER, 2005)We prove existence of nonnegative solutions to -Delta u + u = 0 on a smooth bounded domain Omega subject to the singular boundary derivative condition partial derivative u/partial derivative v = -u(-beta) + lambda f (x, ...
