Fortalecimiento de la toma de decisiones en la asignación de requerimientos de compras en Metro S.A. (Universidad de Chile, 2020)Tradicionalmente la gestión de compras es vista como una actividad que busca aportar con la adquisición de bienes y servicios a los mejores precios, con la calidad exigida y en el tiempo requerido. En metro S.A. esto no ...

(Amer Inst Mathematical Sciences-Aims, 2021)This research is concerned with evolution equations and their forward-backward discretizations. Our rst contribution is an estimation for the distance between iterates of sequences generated by forward-backward schemes, ...
-
(Cambridge University Press, 2018)Full-spectrum dependent types promise to enable the development of correct-by-construction software. However, even certified software needs to interact with simply-typed or untyped programs, be it to perform system calls, ...
-
(Association for Computing Machinery, 2017)We survey foundational features underlying modern graph query languages. We first discuss two popular graph data models: edge-labelled graphs, where nodes are connected by directed, labelled edges, and property graphs, ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2011-05)The Semantic Web is based on the idea of a common and minimal language to enable large quantities of existing data to be analyzed and processed. This triggers the need to develop the database foundations of this basic ...

(EDP Sciences, 2019)Twenty years ago, GRB 980425/SN 1998bw revealed that long gamma-ray bursts (GRBs) are physically associated with broad-lined type-Ic supernovae (SNe). Since then more than 1000 long GRBs have been localized to high angular ...

(2010-02-10)We report molecular line and dust continuum observations, made with the Swedish-ESO Submillimeter Telescope, toward four young high-mass star-forming regions associated with highly luminous (L > 6 × 105 L ) Infrared Astronomical ...
-
(2010-02-10)We present sensitive near-infrared (J, H, and K) imaging observations toward four luminous massive star-forming regions in the Norma Spiral Arm: G324.201+0.119, G328.307+0.432, G329.337+0.147, and G330.949−0.174. We ...
-
(EDP Sciences, 2016)Context. Exoplanet searches have revealed interesting correlations between the stellar properties and the occurrence rate of planets. In particular, different independent surveys have demonstrated that giant planets are ...
-
(2002-06)This article is divided into two chapters. The classical problem of homogenization of elliptic operators with periodically oscillating coe cients is revisited in the rst chapter. Following a Fourier approach, we discuss ...
-
Fourier homogenization method and the propagation of acoustic waves through a periodic vortex array (1999)The classical problem of homogenization of elliptic operators in arbitrary domains with periodically oscillating coe cients is considered. As the period goes to zero, an asymptotic analysis of the corresponding sequence ...
-
(Universidad de Chile, 2013)En esta memoria se extiende el resultado de integración de Correa y Hantoute presentado en \cite{Correa1}, que dice que si un espacio de Banach $X$ tiene la propiedad de Radon-Nykod\'ym (RNP), entonces para todo par de ...
-
(Elsevier, 2016)This paper presents a experimentally-validated fractal time thermal model to describe the discharge and cooling down processes of air-cooled cylindrical Lithium-ion cells. Three cases were studied, a spatially isolated ...
