Los infractores reincidentes en el tráfico: análisis de variables sociodemográficas, personalidad y consumo de alcohol de los asistentes a los cursos…
2015
INTRODUCCIÓN Las intervenciones que se pueden realizar ante el problema de la seguridad vial son muy diversas. Pero entre todas las medidas adoptadas en los últimos años, concretamente a raíz de la puesta en marcha del Plan Estratégico de Seguridad Vial 2005-2008 de la Dirección General de Tráfico, destaca, por su repercusión social y legislativa, la puesta en marcha del Sistema de Permiso por Puntos (SPP). El objetivo principal del SPP es mejorar la seguridad vial a través de la reducción de la reincidencia en la comisión de infracciones, promoviendo un cambio de actitudes y comportamientos en las vías públicas. No obstante, aunque el efecto principal del SPP es disuadir a los conductores …
Thin Film CIGS Solar Cells, Photovoltaic Modules, and the Problems of Modeling
2013
Starting from the results regarding a nonvacuum technique to fabricate CIGS thin films for solar cells by means of single-step electrodeposition, we focus on the methodological problems of modeling at cell structure and photovoltaic module levels. As a matter of fact, electrodeposition is known as a practical alternative to costly vacuum-based technologies for semiconductor processing in the photovoltaic device sector, but it can lead to quite different structural and electrical properties. For this reason, a greater effort is required to ensure that the perspectives of the electrical engineer and the material scientist are given an opportunity for a closer comparison and a common language.…
Semiconductors: Growth and Characterization
2018
Semiconducting materials are widely used in several applications such as photonics, photovoltaics, electronics and thermoelectrics, because of their optical and electro-optical features. The fundamental and technological importance of these materials is due to the unique physical and chemical properties. Over the years, numerous methods have been developed for the synthesis of high efficient semiconductors. Besides, a variety of approach and characterization methods have been used to study the numerous and fascinating properties of the semiconducting materials. This book collects new developments about semiconductors, from the fundamental issues to the synthesis and applications. Special at…
On the use of the EMI for the health monitoring of bonded elements
2014
The low weight, robustness and fatigue resistance of adhesive joints make them suitable for structural joints. A fully developed nondestructive evaluation technique however is needed to monitor and assess the quality of bonded joints. In the present paper the application of the electromechanical impedance (EMI) technique is proposed. In the EMI method a piezoelectric transducer (PZT) is attached to the structure of interest. The high sensitivity and low power consumption make the EMI method feasible for real time structural health monitoring. In this study we investigated the sensitivity of the electromechanical response of a PZT to the curing and the quality of the adhesive used for bonded…
Heavy-Ion-Induced Degradation in SiC Schottky Diodes : Incident Angle and Energy Deposition Dependence
2017
Heavy-ion-induced degradation in the reverse leakage current of SiC Schottky power diodes exhibits a strong dependence on the ion angle of incidence. This effect is studied experimentally for several different bias voltages applied during heavy-ion exposure. In addition, TCAD simulations are used to give insight on the physical mechanisms involved. peerReviewed
Tahtipuikon jäljillä - kapellimestarin asiantuntijuuden rakentuminen
2012
Kapellimestariksi kasvaminen vaatii kymmenien vuosien työn, jossa asiantuntijuuden pohjana on kokemus orkesterisoitosta ja oman instrumentin hyvä hallinta. Kasvumatkalle tarvitaan myös erilaisten ihmisten kohtaamista. peerReviewed
Characterization and processability of molecular-based nanoparticles and 2D crystals by scanning probe microscopy
2014
El desarrollo de nuevos dispositivos multifuncionales se basa en la posibilidad de miniaturización de sus componentes así como de su ensamblado de una manera controlada. Conocer el tamaño, la forma y las propiedades de estos nanocomponentes así como poder integrarlos y combinarlos a voluntad son factores cruciales a la hora de diseñar dispositivos inteligentes que integren estas nanoestructuras con macro(nano) electrodos. El reto que se plantea tiene pues dos vertientes: por un lado la caracterización y manipulación de nuevos materiales en la nanoescala, y por otro, su organización en superficies y/o su ensamblado para crear materiales multifuncionales heteroestructurados. En esta tesis se …
Superconducting tunnel junction fabrication on three-dimensional topography based on direct laser writing
2020
Superconducting junctions are widely used in a multitude of applications ranging from quantum information science and sensing to solidstate cooling. Traditionally, such devices must be fabricated on flat substrates using standard lithographic techniques. In this study, we demonstrate a highly versatile method that allows for superconducting junctions to be fabricated on a more complex topography. It is based on maskless direct laser writing and two-photon lithography, which allows writing in 3D space. We show that high-quality normal metal–insulator–superconductor tunnel junctions can be fabricated on top of a 20-lm-tall three-dimensional topography. Combined with conformal resist coating m…
High Bias Voltage CZT Detectors for High-flux Measurements
2017
In this work, we present the performance of new travelling heater method (THM) grown CZT detectors, recently developed at IMEM-CNR Parma, Italy. Thick planar detectors (3 mm thick) with gold electroless contacts on CZT crystals grown by Redlen Technologies (Victoria BC, Canada) were realized, with a planar cathode covering the detector surface (4.1 x 4.1 mm(2)) and a central anode (2 x 2 mm(2)) surrounded by a guard ring electrode. The detectors, characterized by low leakage currents at room temperature (4.7 nA/cm(2) at 1000 V/cm), allow good room temperature operation even at high bias voltages (> 7000 V/cm). At low rates, the detectors exhibit an energy resolution around 4 % FWIEM at 59.5…
Salud vial: ¿el conductor a terapia?
2009
El Instituto Universitario de Investigación en Tráfico y Seguridad Vial (INTRAS) y Attitudes (programa social de Audi), tras la publicación de los libros "Salud vial: Teoría y prácticas de los trastornos físicos y psíquicos en la conducción." y "Salud vial: Diagnóstico de los conductores españoles.", se plantearon como actividad complementaria la realización de unas jornadas que cumplieran los siguientes objetivos: • Permitir avanzar en el conocimiento y la implementación de medidas que contribuyan a una mejora de la seguridad vial. • Servir como foro de expresión para científicos y profesionales con un tono constructivo, plural e integrador. • Tener un componente de difusión tanto al públi…
