-
(Springer, 2018)Epi-Lipschitz sets in normed spaces are represented as sublevel sets of Lipschitz functions satisfying a so-called qualification condition. Canonical representations through the signed distance functions associated with ...
-
(Universidad de Chile, 2017)Mass is arguably the most important property of a star: along with the initial distribution of chemical elements, stellar mass is responsible for the evolution and structure of these objects. The only means for calculating ...
-
(Universidad de Chile, 2017)Este trabajo presenta el desarrollo de un modelo de negocios para una start-up tecnológica enfocada en optimizar el proceso de venta de productos alimenticios cercanos a expirar o excedentes de producción, logrando además ...
-
Modelling and implementation of a protocol for partially connected topologies in underground mines (Universidad de Chile, 2017)Establecer canales de comunicación confiables en minas subterráneas es crucial para poder llevar a cabo operaciones eficientes y seguras; sin embargo, las condiciones extremas propias del entorno y la topología de túneles ...
-
(Universidad de Chile, 2017)El presente trabajo de tesis pretende resolver una problemática al interior de Informática en la institución bancaria BCI. El Banco BCI contempla una Gerencia de Informática, la cual está compuesta por diversas unidades ...
-
(Universidad de Chile, 2017)Actualmente el sistema de transporte público Transantiago presenta un alto índice de evasión que se resume en que uno de cada tres chilenos no paga su pasaje. Una parte esencial para estudiar la evasión es estimar correctamente ...
-
(Elsevier SCI Ltd, 2018)Although higher Education Institutions (HEIs) have seen a blossoming of sustainability initiatives of various kinds in recent years, the variety of institutional and socio-economic contexts brings about an equally plural ...
-
(EDP Sciences, 2018)Aims. With the purpose of investigating the radio emission of new ultracool objects, we carried out a targeted search in the recently discovered system VHS J125601.92-125723.9 (hereafter VHS 1256-1257); this system is ...
-
(Springer, 2018)In this work we give an extension of the Brondsted-Rockafellar Theorem, and some of its important consequences, to proper convex lower-semicontinuous epi-pointed functions defined in locally convex spaces. We use a new ...
-
(National Academy of Sciences, 2018)Mineral dust aerosols cool Earth directly by scattering incoming solar radiation and indirectly by affecting clouds and biogeochemical cycles. Recent Earth history has featured quasi-100,000-y, glacial-interglacial climate ...
-
(Elsevier SCI Ltd, 2018)A distribution-free approach is proposed to estimate the fracture size distribution from a given trace length distribution, assuming that the fracture network can be represented by a Poisson-disc model. This approach ...
-
(Elsevier, 2018)In this work, we present the synthesis of Ag doped TiO2 materials. The products are characterized by powder X-ray diffraction, transmission electron microscopy, X-ray photoelectron spectroscopy, nitrogen adsorption, and ...
-
(Springer, 2018)Software engineering research now considers that no system is an island, but it is part of an ecosystem involving other systems, developers, and users. When a framework or a library evolves, its clients often must adapt. ...
-
(Elsevier, 2018)Public transport systems with electronic fare collection devices continuously store data related to trips taken by users, which contain valuable information for planning and policy analysis. However, if the card is not ...
-
(IOP Publishing Ltd, 2018)The construction of affine interval exchange maps (IEMs) with wandering intervals that are semi-conjugate to a given self-similar IEM is strongly related to the existence of the so-called minimal sequences associated with ...
-
(AI Access Foundation, 2018)Bisimulation provides structural conditions to characterize indistinguishability from an external observer between nodes on labeled graphs. It is a fundamental notion used in many areas, such as verification, graph-structured ...
-
(Springer, 2018)Finding low-cost spanning subgraphs with given degree and connectivity requirements is a fundamental problem in the area of network design. We consider the problem of finding d-regular spanning subgraphs (or d-factors) of ...
-
(Japan Antibiotics Research Association, 2018)Bio-guided fractionation of the culture broth extract of Streptomyces asenjonii strain KNN 42.f recovered from an extreme hyper-arid Atacama Desert soil in northern Chile led to the isolation of three new bioactive ...
-
(Elsevier, 2018)In this paper we use a continuum mixture model to solve numerically the momentum and continuity equations associated with the sedimentation dynamics of highly concentrated fluid-solid mixtures in tilted ducts at low ...
-
(EDP Sciences, 2018)Transient surveys have recently revealed the existence of H-rich super-luminous supernovae (SLSN; e. g., iPTF14hls, OGLE-SN14-073) that are characterized by an exceptionally high time-integrated bolometric luminosity, a ...
