Evaporation kinetics in swollen porous polymeric networks
(2014)Polymer matrices with well defined structure and pore sizes are widely used in several areas of chemistry such as catalysis, enzyme immobilization, HPLC, adsorbents or controlled drug release. These polymers have pores in ... -
Excitación de electrones K del Li a baja transferencia de momento por dispersión inelástica de rayos X en LiH
(2015)Se presenta un estudio del espectro de excitaciones de electrones de coraza K del Li en LiH mediante dispersión inelástica de rayos x medido en alta resolución. La contribución de los electrones de coraza se extrae del ... -
External visual interface for a Nikon 6D autocollimator
(2014)The goal of this paper is to describe the potential of a visual interface applied to a Nikon 6B/6D autocollimator in order to replace human operator within a laboratory grade measurement. The optical interface implemented ... -
Identificación por espectroscopia de ESR de especies magnéticas de Fe depositadas por un método post-síntesis en materiales del tipo Mcm-41
(2014-09)Se prepararon silicatos mesoporosos del tipo MCM41 modificados con Fe, mediante el método de impregnación húmeda. Se evaluó la influencia del contenido de Fe mediante caracterización estructural y espectroscópica de los ... -
Licentia : a tool for supporting users in data licensing on the web of data
(2014)Associating a license to data is a fundamental task when publishing data on the Web. However, in many cases data producers and publishers are not legal experts, and they usually have only a basic knowledge about the possible ... -
Lightning activity in the Southern Coast of Chile
(2014)Based on eight years of lightning data (from January 2005 to December 2012) from the World Wide Lightning Location Network (WWLLN) we describe the spatial distribution and temporal variability of lightning activity over ... -
Longitudinal gradient-coil with improved uniformity within the volume of interest
(2014)We present a longitudinal magnetic fieldgradient-coil with optimized uniformity within the volume ofinterest (VOI). The accuracy of the optimization algorithm wasconfronted with measurements of the spatial dependence of ... -
Mining human interactions to construct a virtual guide for a virtual fair
(Association for Computational Linguistics, 2014)In this paper we describe how we mine interactions between a human guide and a human visitor to build a virtual guide. A virtual guide is an agent capable of fulfilling the role of a human guide. Its goal is to guide ... -
A Natural Language Instructor for pedestrian navigation based in generation by selection
(Association for Computational Linguistics, 2014)In this paper we describe a method for developing a virtual instructor for pedestrian navigation based on real interactions between a human instructor and a human pedestrian. A virtual instructor is an agent capable ... -
New geometries for the characterization of dark matter phenomena
(2014)We present some new geometries with spheroidal symmetry, with and without mass, that involve new kind of energy momentum tensors, and which are suitable for the description of dark matter phenomena. -
Pd/Ti electrocatalysts intechnological significance reactions
(2014)Nuestro objetivo es presentar sistemas, tecnológicamente importantes, que operen como futuros electrocatalizadores en la detección de contaminantes o en celdas de combustible. Así, nanoelectrodos de Pd/Ti, se aplican ... -
Un proyecto basado en educación matemática crítica para prevenir contaminación por falta de red cloacal
(2014)En este trabajo se reflexiona a partir de una experiencia áulica con un proyecto pedagógico que, atendiendo a una Educación Matemática Crítica, busca generar un auténtico escenario de investigación. El proyecto se ejecuta ... -
Sistema de realidad acústica virtual en tiempo real: AVRS
(2014)En este trabajo se presenta un sistema experimental dinámico e interactivo de realidad acústica virtual. El sistema, llamado AVRS, es de código abierto, flexible, escalable y modular. Funciona en una computadora estándar ... -
Structural and magnetic changes induced by electron and ion irradiation on HOPG
(2015)In recent decades, many studies reported magnetism in carbon-based materials. This phenomenon was attributed to structural defects within the sample. Many authors showed an increase of magnetization in HOPG (Highly Oriented ... -
Variación de las propiedades magnéticas y estructurales de nanohilos de Ni en función de su diámetro
(2014)Se estudiaron las propiedades de histéresis magnética de arreglos ordenados de nanohilos de Ni, electrodepositados éstos en una membrana de alúmina con un arreglo hexagonal de poros cilíndricos. Se analizó el efecto de la ...
