A multipurpose experimental facility for advanced X-ray Spectrometry applications
(2014)
Motivation, Ultra High Vacuum Chamber (UHVC) project: To support/enhance the training of scientists/engineers from developing countries in the operation of synchrotron radiation instrumentation; To provide beam time access ...
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.
A Tool for GIXRF/XRR simulation and data analysis
(2014)
The IAEA has developed a beamline end-station facility that it is currently installed at the newly developed XRF beamline of Elettra Sincrotrone Trieste, ItalyThe end-station called Ultra High Vacuum Chamber (UHVC) is ...
Diurnal patterns in lightning activity over South America
(2014)
Satellite and ground network observations of lightning flash distribution data are used to examine the diurnal cycle of lightning activity over the tropical and subtropical regions of South America. The results show in ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
