Random Laser Action in Nd:YAG Crystal Powder Jon
(MDPI, 2016-05-13)
This work explores the room temperature random stimulated emission at 1.064 mu m of a Nd:YAG crystal powder (Neodymium-doped yttrium aluminum garnet) in a very simple pump configuration with no assistance from an internal ...
Literatura, ciudad e imaginarios urbanos: el País Vasco y la literatura francesa
(2018)
El presente trabajo analiza la evolución de la representación literaria del País Vasco, comparando la imagen que Pierre Loti construyó a finales del siglo XIX con la imagen del País Vasco que aparece en obras literarias ...
Fabrication and Characterization of Polymer Optical Fibers Doped with Perylene-Derivatives for Fluorescent Lighting Applications
(MDPI, 2017-08)
Four different dye-doped polymer optical fibers (POFs) have been fabricated following a two-step fabrication process of preform extrusion and fiber drawing, using poly-(methyl methacrylate) (PMMA) as host material and dye ...
Polymer-Optical-Fiber Lasers and Amplifiers Doped with Organic Dyes
(MDPI, 2011-09)
Polymer optical fibers (POFs) doped with organic dyes can be used to make efficient lasers and amplifiers due to the high gains achievable in short distances. This paper analyzes the peculiarities of light amplification ...
TrhOnt: building an ontology to assist rehabilitation processes
(Biomed Central, 2016-10-04)
Background: One of the current research efforts in the area of biomedicine is the representation of knowledge in a structured way so that reasoning can be performed on it. More precisely, in the field of physiotherapy, ...
Traduire dans une société multilingue: l'autotraduction littéraire au Pays Basque
(Société des Hispanistes Français, 2018)
Les sociétés multilingues, où plusieurs langues et littératures se partagent un espace commun et entretiennent des relations hiérarchiques complexes et dynamiques, se sont révélées à plusieurs reprises être un point de ...
Characterization of Chromatic Dispersion and Refractive Index of Polymer Optical Fibers
(MDPI, 2017-12-20)
The chromatic dispersion and the refractive index of poly(methyl methacrylate) polymer optical fibers (POFs) have been characterized in this work by using a tunable femtosecond laser and a Streak Camera. The characterization ...
Pitch Angle Misalignment Correction Based on Benchmarking and Laser Scanner Measurement in Wind Farms
(MDPI, 2018-12-01)
In addition to human error, manufacturing tolerances for blades and hubs cause pitch angle misalignment in wind turbines. As a consequence, a significant number of turbines used by existing wind farms experience power ...
Nature and origin of white efflorescence on bricks, artificial stones, and joint mortars of modern houses evaluated by portable Raman spectroscopy and laboratory analyses
(Elsevier, 2015-02-05)
Bricks and mortar currently constitute one of the most important building materials used in the
construction of most modern facades. The deterioration of these materials is caused primarily by the
impact of numerous ...
Fabrication of Active Polymer Optical Fibers by Solution Doping and Their Characterization
(MDPI, 2018-12-31)
This paper employs the solution-doping technique for the fabrication of active polymer optical fibers (POFs), in which the dopant molecules are directly incorporated into the core of non-doped uncladded fibers. Firstly, ...
