(Universidad de Chile, 2011)En Chile, el 37,6% de establecimientos educacionales pertenecen al ámbito de la ruralidad; no obstante sólo el 9,32% de los alumnos viven en zonas rurales. Muchas de las escuelas rurales son pequeñas, con un solo profesor ...
-
(Universidad de Chile, 2018)Este trabajo presenta un sistema de Localización y Mapeo Simultáneo (SLAM) de robots humanoides basado en la fusión del sistema ORB-SLAM con información propioceptiva. El objetivo es desarrollar una metodología que permita ...
-
(Universidad de Chile, 2011)Los establecimientos educacionales del área rural de Chile presentan algunas ineficiencias: infraestructura deficiente, cursos multigrados, relación alumno-profesor muy baja y una localización que obliga a los alumnos a ...
-
(Universidad de Chile, 2023)El estudio de la Materia Condensada es el área de la Física con más investigadores(as) a nivel mundial. En general los fenómenos de localización y transporte son de gran relevancia en esta área de estudio, los cuales tienen ...
-
(Amer Physical Soc, 2020)We consider a two-dimensional octagonal-diamond network with a fine-tuned diagonal coupling inside the diamond-shaped unit cell. Its linear spectrum exhibits coexistence of two dispersive bands (DBs) and two flat bands ...
-
(ELSEVIER SCIENCE BV, 2005-10-01)he existence, stability properties, dynamical evolution and bifurcation diagram of localized patterns and hole solutions in one-dimensional extended systems are studied from the point of view of front interactions. An ...
-
(American Physiological Society, 2015)We investigate the formation of a localized plateau beam in the transverse section of a nonlinear optical ring cavity filled with a metamaterial and a nonlocal medium such as a nematic liquid crystal. We show that, far ...
-
(ELSEVIER, 2010)A time-periodic magnetic field applied transversally to the hard axis of an extended easy-plane ferromagnetic sample can produce parametric resonance. For the 2:1 resonance, the prototype orderparameter- equation derived ...
-
(AMER PHYSICAL SOC, 2008-05)We study theoretically a family of localized states which asymptotically connect a uniform oscillatory state in the magnetization of an easy-plane ferromagnetic spin chain when an oscillator magnetic field is applied ...
-
(AMERICAN PHYSICAL SOC, 2006-06)We present a unifying description close to a spatial bifurcation of localized states, appearing as large amplitude peaks nucleating over a pattern of lower amplitude. Localized states are pinned over a lattice spontaneously ...
-
(Springer, 2017)Driven damped coupled oscillators exhibit complex spatiotemporal dynamics. An archetype model is the driven damped sine-Gordon equation, which can describe several physical systems such as coupled pendula, extended Josephson ...
-
(2005)We study numerically a prototype equation which arises generically as an envelope equa- tion for a weakly inverted bifurcation associated to traveling waves: The complex quintic Ginzburg{Landau equation. We show six di ...
-
(American Physical Society, 2015)We investigate the formation of localized structures with varying widths in one- and two-dimensional systems. The mechanism of stabilization is attributed to strongly nonlocal coupling mediated by a Lorentzian type ...
-
(EPL ASSOCIATION, EUROPEAN PHYSICAL SOCIETY, 2012-02)The pattern formation in a magnetic wire forced by a transversal uniform and oscillatory magnetic field is studied. This system is described in the continuous framework by the Landau-Lifshitz-Gilbert equation. We find ...
-
(Springer, 2023)In Stackelberg security games, a leader locates security resources to protect a set of targets from strategic adversaries that aim to attack these targets after observing the leader’s strategy. In this setting, the leader ...
-
(2016)Location privacy is a concern in mobile networks monitoring systems. We propose a model using homomorphic encryption, where researchers can compute aggregations, learning nothing more about users' location than the result ...
-
(Nature Research, 2021)As the novel coronavirus (COVID-19) pandemic spread across the world over the past year, many countries imposed lockdowns in the form of stay at home requirements on their citizens to mitigate its spread. We analyze mobility ...
-
(Oxford University Press, 2016)We test the assumption of hydrostatic equilibrium in an X-ray luminosity selected sample of 50 galaxy clusters at 0.15 < z < 0.3 from the Local Cluster Substructure Survey (LoCuSS). Our weak-lensing measurements of M500 ...
-
(Oxford University Press, 2018-07)Galaxy clusters are expected to form hierarchically in a Lambda cold dark matter (Lambda CDM) universe, growing primarily through mergers with lower mass clusters and the continual accretion of group-mass haloes. Galaxy ...
-
(IOP Publishing, 2015)We present a study of the spatial distribution and kinematics of star-forming galaxies in 30 massive clusters at 0.15 < z < 0.30, combining wide-field Spitzer 24 mu m and GALEX near-ultraviolet imaging with highly complete ...
