This thesis analyses the effects of two-photon interference in a polarisation squeezed state under two different points of view: on one hand, it presents a new method to obtain the temporal wavefunction of a state of two ...
The work presented in this thesis, mostly experimental, is based on three main pillars: the concepts of entanglement, Bell's inequalities and coherence. Entanglement is a very special type of correlation that can exist ...
(English) Since last decade, tourism in Chilean Patagonia has grown rapidly, largely promoted by State policies and encouraged by privately held companies, whose objective is to turn this region into a pole of attraction ...
This doctoral thesis aims the theoretical and exploratory study of methodologies and mechanisms for automating 4D modeling, applied in the processes planning of volumetric construction in steel. We assume that in architecture, ...
El objetivo de esta tesis es el estudio de la dinámica de los láseres de semiconductor (LS) con realimentación óptica, tanto desde el punto de vista experimental como numérico. La reflexión de la luz emitida por el láser, ...
The motivation for the research starts from the interest in understanding the rules of urban composition and the attributes of urbanity that blossom in the Franco’s Colonization oeuvre developed during the period 1944-1965, ...

This thesis covers investigation of the surface phenomena of Ti-6Al-4V and Ti-6Al-2Sn-4Zr-2Mo alloys related with oxidation at elevated temperature and corrosion during chemical treatment in hydrofluoric-nitric acid (HF/HNO3) ...
The main objective of this PhD thesis is the study of coal mine dust patterns produced by different types of mining operations and different types of coal. In addition, the potential links between oxidative potential (OP) ...
(English) Agriculture not only contributes to more than a quarter of all global greenhouse gas emissions but is also the number one anthropogenic source of nitrogen emissions and a danger to nearly half of threatened ...
Due to the continuously increasing energy demand and the environmental concerns about climate changes raised by international community, alternative energy resources have been put under intense investigation for the past ...
(English) The availability of energy is a fundamental ingredient for the development of society. However, the intense consumption of fossil fuels as an energy resource since the second industrial revolution has caused a ...
In a global context of population ageing, many research are conducted to improve the quality of life of older people living in assisted living facilities, but few of these works develop an architectural approach .This ...
La celulosa es el polímero más abundante en la Tierra y en los últimos años ha ganado un amplio interés como fuente de nuevos productos con requisitos de procesamiento y de calidad diferentes a los procesos convencionales ...
In the current scenario of growing environmental concerns, the search for innovative, renewable, non-polluting materials has never been as intensive as it is today. Cellulose, being the most abundant polymer on earth, ...
