El objetivo del presente trabajo es realizar un comparativo estudio de la implantación de un plan de pensiones de jubilación por parte de la empresa demandante GEMASA a favor de sus empleados. Para ello, con base en un análisis del colectivo trabajador así como del plan de pensiones diseñado específicamente para la empresa, se medirá la capacidad de motivación de los empleados y su capacidad de generación de beneficios ante mejoras salariales. Mediante la creación de diferentes escenarios, se llevará a cabo un análisis financiero de las cuenta de la compañía.

[ES] En este trabajo se ha realizado un estudio del funcionamiento del mercado inmobiliario de la Comunidad de Andalucía en comparación con el territorio español durante el periodo 2000-2014. El presente análisis pretende dar una visión global de la situación del mercado inmobiliario e implícitamente del entorno económico en el último decenio y de las dificultades de acceso a una vivienda en la actualidad. La vivienda es un elemento relevante para la sociedad y la economía del país tanto en lo relacionado con el sector de la construcción como para el bienestar de las personas ya que supone la mayor inversión para la gran parte de las familias españolas. Se han llevado a cabo estudios de series de datos estadísticos de los diferentes indicadores y factores para ver los efectos que han tenido tanto en el periodo de boom como en la posterior crisis y exponer resultados y conclusiones en base a ello. La crisis ha generado un problema de carácter social relacionado con el mercado de la vivienda: el difícil acceso a una vivienda y los desahucios, que también se han abordado en este estudio y se han expuesto las políticas de ayuda que se están implantando en la Comunidad Andaluza.

Reaching the strong coupling regime of light-matter interaction has led to an impressive development in fundamental quantum physics and applications to quantum information processing. Latests advances in different quantum technologies, like superconducting circuits or semiconductor quantum wells, show that the ultrastrong coupling regime (USC) can also be achieved, where novel physical phenomena and potential computational benefits have been predicted. Nevertheless, the lack of effective decoupling mechanism in this regime has so far hindered control and measurement processes. Here, we propose a method based on parity symmetry conservation that allows for the generation and reconstruction of arbitrary states in the ultrastrong coupling regime of light-matter interactions. Our protocol requires minimal external resources by making use of the coupling between the USC system and an ancillary two-level quantum system.

Cloud chambers were essential devices in early nuclear and particle physics research. Superseded by more modern detectors in actual research, they still remain very interesting pedagogical apparatus. This thesis attempts to give a global view on this topic. To do so, a review of the physical foundations of the diffusion cloud chamber, in which an alcohol is supersaturated by cooling it with a thermal reservoir, is carried out. Its main results are then applied to analyse the working conditions inside the chamber. The analysis remarks the importance of using an appropriate alcohol, such as isopropanol, as well as a strong cooling system, which for isopropanol needs to reach −40ºC. That theoretical study is complemented with experimental tests that were performed with what is the usual design of a home-made cloud chamber. An effective setup is established, which highlights details such as a grazing illumination, a direct contact with the cooling reservoir through a wide metal plate, or the importance of avoiding vapour removal. Apart from that, video results of different phenomena that cloud chamber allow to observe are also presented. Overall, it is aimed to present a physical insight that pedagogical papers usually lack.

Circuit quantum electrodynamics, consisting of superconducting artificial atoms coupled to on-chip resonators, represents a prime candidate to implement the scalable quantum computing architecture because of the presence of good tunability and controllability. Furthermore, recent advances have pushed the technology towards the ultrastrong coupling regime of light-matter interaction, where the qubit-resonator coupling strength reaches a considerable fraction of the resonator frequency. Here, we propose a qubit-resonator system operating in that regime, as a quantum memory device and study the storage and retrieval of quantum information in and from the Z(2) parity-protected quantum memory, within experimentally feasible schemes. We are also convinced that our proposal might pave a way to realize a scalable quantum random-access memory due to its fast storage and readout performances.

The present work is focused on the measurement of workers exposure to nano-TiO2 in the life cycle steps of depollutant mortars. It has been done in the framework of the SCAFFOLD project, which aims at the management of potential risks arising from the use of manufactured nanomaterials in construction. Main findings can be summarized as follows: (1) The occupational exposure to nano-TiO2 is below 0.3 mg/m(3) for all measured scenarios. The highest concentrations were measured during the cleaning task (in the nano-TiO2 manufacturing process) and during the application (spraying) of depollutant coatings on a wall. (2) It was found a high release of particles above the background in several tasks as expected due to the nature of the activities performed. The maximum concentration was measured during drilling and during adding powder materials (mean total particle concentration up to 5.591E+04 particles/cm(3) and 5.69E+04 particles/cm(3)). However, considering data on total particle concentration released, no striking differences have been observed when tasks have been performed using conventional materials in the sector (control) and when using materials doped with nano-objects.
