Emociones y personalidad en la adopción de eWOM, modelo causal y análisis de neuromarketing
2020
El desarrollo de esta tesis, como su título indica, es el análisis del eWOM a través de la personalidad y las emociones en el ámbito del turismo, a través de un a análisis consciente con una encuesta y con un análisis no consciente mediante una herramienta de neuromarketing. La importancia de este trabajo se basa en la progresiva importancia que están teniendo los comentarios online en nuestro día a día, y más concretamente en el sector turístico y en su potencial relación con la personalidad y las emociones a la hora de la reserva en la web. La presente tesis doctoral tiene por finalidad, diseñar y contrastar empíricamente un modelo de relaciones causales, que analiza los efectos en la con…
Latest Developments and Results of Radiation Tolerance CMOS Sensors with Small Collection Electrodes
2020
The development of radiation hard Depleted Monolithic Active Pixel Sensors (DMAPS) targets the replacement of hybrid pixel detectors to meet radiation hardness requirements of at least 1.5e16 1 MeV neq/cm2 for the HL-LHC and beyond. DMAPS were designed and tested in the TJ180 nm TowerJazz CMOS imaging technology with small electrodes pixel designs. This technology reduces costs and provides granularity of 36.4x36.4 um2 with low power operation (1 uW/pixel), low noise of ENC < 20 e-, a small collection electrode (3 um) and fast signal response within 25 ns bunch crossing. This contribution will present the latest developments after the MALTA and Mini-MALTA sensors. It will illustrate the imp…
Tracking oneself for others: communal and self-motivational value of sharing exercise data online
2021
Self-tracking is increasingly popular in recreational sport. Leisure sports practitioners use wearable devices that are connected to online platforms to record, analyse, and share their exercise data. While doing that they interact with a digital system, with themselves, and with peers. This paper examines social-communicative aspects of self-tracking, and the support that these aspects and their associated practices may provide for physical activity behaviour. Data for the study was collected using an online survey and in-depth interviews with Finnish trail runners. The results indicate that sharing exercise data with others on a regular basis can support physical activity behaviour becaus…
Effects of non-tracking solar collector orientation on energy production : photovoltaic systems
2012
Abstract: This Master's thesis proposes a new method for calculating the optimum tilt and orientation angle of a fitted solar collector. In addition to using geographical data, this method takes into account the radiation data and weather statistics of prospective locations. This makes the calculations valid not only for certain latitudes, but also for certain radiation and weather conditions. Calculations were done by estimating the energy production of a given solar array using a sequence of different tilt angles and orientation angles. Special attention was given to shaded solar arrays and arrays made up of photovoltaic modules. Specific radiation and weather data was used for both locat…
Microscopy method and apparatus for optical tracking of emitter objects
2017
Microscopy method and apparatus for determining the posi tions of emitter objects in a three - dimensional space that comprises focusing scattered light or fluorescent light emitted by an emitter object, separating the focused beam in a first and a second optical beam, directing the first and the second optical beam through a varifocal lens having an optical axis such that the first optical beam impinges on the lens along the optical axis and the second beam impinges decentralized with respect to the optical axis of the varifocal lens , simultaneously capturing a first image created by the first optical beam and a second image created by the second optical beam , and determining the relativ…
Error analysis and calibration for a novel pipe profiling tool
2020
Integrity of industrial pipework is ensured through routine inspection. Internal visual inspection tools are capable of characterising degradation in the form of corrosion, pitting, erosion and cracking. The accuracy of such inspection systems has a direct impact on decisions regarding the remaining lifetime of the asset. By minimising error margins, the asset may be operated with confidence for longer, with less uncertainty. This paper considers a probe system consisting of a laser profiler and camera that produces a textured 3D model of the internals of 2 – 6 inch pipework. The accuracy of the system is defined by the ability to extract laser projections from an image as it travels down t…
Estudio y optimización de nuevos catalizadores para la producción selectiva de olefinas ligeras
2017
El cambio climático ha sido calificado como el mayor de los problemas a los que se enfrenta la humanidad actualmente. Sus consecuencias pueden ser extremas y pueden poner en peligro a todas las especies que habitan este planeta. La solución implica necesariamente un esfuerzo global, tanto a nivel político como científico. Afortunadamente, los químicos e ingenieros químicos tienen a su alcance poderosas herramientas con las que contribuir, incluyendo la química sostenible y, en particular, la catálisis. La catálisis permite hacer un uso más eficiente de los recursos que requieren de una transformación química. Los recursos fósiles son la principal reserva de carbono al alcance del ser humano…
Incidence de la clarification des moûts de raisin sur les fermentescibilltés alcoolique et malolactique
1993
<p style="text-align: justify;">Des essais de débourbage en vinification en blanc, réalisés de 1988 à 1992, mettent en évidence le rôle important joué par la teneur en macromolécules solubles dans le moût de raisin. Les moûts de faible turbidité conduisent en effet à des fermentations alcooliques lentes en relation avec de faibles populations levuriennes. Il est également confirmé que la libération de polysaccharides exocellulaires par les levures au cours de la fermentation alcoolique est d'autant plus élevée que le moût de départ a été fortement appauvri en colloïdes de raisin. Par contre, ce sont dans les lots les plus clarifiés que l'on observe la meilleure fermentescibilité malol…
A GEM-TPC in twin configuration for the Super-FRS tracking of heavy ions at FAIR
2018
The GEM-TPC [1] described herein will be part of the standard beam-diagnostics equipment of the Super-FRS [2] . This chamber will provide tracking information for particle identification at rates up to 1 MHz on an event-by-event basis. The key requirements of operation for these chambers are: close to 100% tracking efficiency under conditions of high counting rate, spatial resolution below 1 mm and a superb large dynamic range covering projectiles from Z=1 up to Z=92. The current prototype consists of two GEM-TPCs inside a single vessel, which are operating independently and have electrical drift fields in opposite directions. The twin configuration is done by flipping one of the GEM-TPCs o…
