(Universidad de Chile, 2016)El objetivo de este trabajo es caracterizar y determinar el origen petrogenético de la Unidad Guanaco, que corresponde al primer registro de actividad volcánica de edad Cretácico Tardío en la Cordillera Principal de Chile ...
-
(Universidad de Chile, 2008)A partir del año 2001 la División andina de CODELCO Chile comenzó la puesta en práctica de una estructuración sobre la base de unidades de negocio autónomas. La existencia de dichas unidades de negocio autónomas ha ...

(Taylor & Francis, 2015)In this paper we consider a smooth bounded domain < subset of>(N) and a parametric family of radially symmetric kernels K-epsilon: (N)(+) such that, for each epsilon (0, 1), its L-1-norm is finite but it blows up as epsilon ...
-
(Springer, 2020)We consider the Robin boundary value problem div(A del u) = div f + F in Omega, a C-1 domain, with (A del u - f) . n + alpha u = g on Gamma, where the matrix A belongs to VMO(R-3), and discover the uniform estimates on ...
-
(MDPI, 2022)The Levelized Cost of Driving (LCOD) calculates how much it costs to drive a vehicle, per kilometer, over the vehicle lifespan, and it is typically measured in USD/km. LCOD has been widely applied to assess and compare ...
-
(SPRINGER, 2008-04)We consider the problem of nding a singularity of a vector eld X on a complete Riemannian manifold. In this regard we prove a uni ed result for local convergence of Newton's method. Inspired by previous work of Zabrejko ...
-
(IOP Publishing, 2020)In this work, the impact of different HfO2/Al2O3-based multilayer dielectric stack (DS) configurations on the electrical characteristics and on the resistive switching (RS) performance of Ni/Insulator/Silicon devices has ...
-
(ELSEVIER, 2006-05-01)We analyze the inverse problem of the identification of a rigid body immersed in a fluid governed by the stationary Boussinesq system. First, we establish a uniqueness result. Then, we present a new method for the partial ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008-09-01)In this article we prove that the semi-linear elliptic partial differential equation -Delta u + u = u(p) in Omega u > 0 in Omega. u = 0 on partial derivative Omega possesses a unique positive radially symmetric ...
-
(Elsevier, 2019)The rise of repetitive datasets has lately generated a lot of interest in compressed self-indexes based on dictionary compression, a rich and heterogeneous family of techniques that exploits text repetitions in different ...
-
(Pergamon-Elsevier, 2016)Indexing highly repetitive collections has become a relevant problem with the emergence of large repositories of versioned documents, among other applications. These Collections may reach huge sizes, but are formed mostly ...
-
(AMER PHYSICAL SOC, 2008-02)A universal analytical expression for the supercritical bifurcation shape of transverse one-dimensional (1D) systems in the presence of additive noise is given. The stochastic Langevin equation of such systems is solved ...
-
(Institute of Electrical and Electronics Engineers, 2020)Motivated from the fact that universal source coding on countably infinite alphabets (infinity-alphabets) is not feasible, this work introduces the notion of "almost lossless source coding". Analog to the weak variable-length ...
-
(American Physical Society, 2015)We experimentally study the critical properties of the nonequilibrium solid-liquid-like transition that takes place in vibrated granular matter. The critical dynamics is characterized by the coupling of the density field ...
-
(SPRINGER-VERLAG BERLIN, 2006)Simultaneous Broadcast protocols allow different parties to broadcast values in parallel while guaranteeing mutual independence of the broadcast values. The problem of simultaneous broadcast was suggested by Chor et al. ...
-
(Universidad de Chile, 2015)Las iniciativas provenientes de las universidades regionales para impactar el desarrollo económico local son diversas en sus diseños, gestión y resultados, por lo que identificar las características deseables que deben ...
-
(Oxford University Press, 2018)We present the discovery of NGTS-3Ab, a hot Jupiter found transiting the primary star of an unresolved binary system. We develop a joint analysis of multi-colour photometry, centroids, radial velocity (RV) cross-correlation ...
-
(American Chemical Society, 2017)The electronic structure of self-assembled monolayers (SAMs) formed by thiols of different lengths and dithiol molecules bound to Au(111) has been characterized. Inverse photoemission spectroscopy (IPES) and density ...
-
(Elsevier, 2020)Water contaminated by arsenic is a tremendous risk for health and environment due to its toxic and carcinogenic nature thus asking for more advanced and efficient removal strategies. Therefore, the aim of this study is to ...
