The goal of this thesis has been the development of a new class of advanced solid-state photonic sources for the mid-infrared (mid-IR) spectral regions, where there exists a severe shortage of practical coherent laser ...
The weight of electric and electronic components of cars has been uninterruptedly increasing through the last decades, and thus the weight of their wiring harnesses. This fact has awakened the interest of car manufacturers ...
This Thesis aims at the development of two novel families of inorganic phosphate cements with suitable characteristics for clinical applications in hard tissue regeneration or replacement. It is organized in two distinct ...
A prerequisite for safe and stable operation of an electric power system is the accurate and reliable measurement of the system parameters, in particular, current and voltage. Conventionally, this has been achieved on High ...
The cell membrane is the encompassing protective shield of every cell and it is composed of a multitude of proteins, lipids and other molecules. The organization of the cell membrane is inextricably intertwined with its ...
The mid-infrared (mid-IR) spectral region coincides with fundamental rotational-vibrational transitions of a large number of molecules in the gas phase. The strong interaction between mid-IR light sources and these gaseous ...
In everyday life the impact of light on the motion of mechanical objects is negligible. However, modern experiments making use of high quality optical resonators are able to observe significant effects originating from the ...
We are facing a global climate crisis that is demanding a change in the status quo of how we produce, distribute and consume energy. In the last decades, this is being redefined through Smart Grids(SG), an intelligent ...
Spatial vision features play a key role in human vision quality, which in turn depends on the retinal image quality and posterior neural processing. The retinal image is affected by three optical phenomena: diffraction, ...
The rate of annual data generation grows exponentially. At the same time, there is a high demand to analyze that information quickly. In the past, every processor generation came with a substantial frequency increase, ...
(English) This thesis addresses the development and evaluation of novel tools and strategies for Environmental Management Systems (EMS) implementation in ports for water quality. Integrating computer vision-based systems ...
(English) During the last years, electro-acoustic technology has been a key factor in the development of portable devices thanks to its high performance and very compact filtering structures. Such a technology has enabled ...
As the rate of annual data generation grows exponentially, there is a demand to manage, query and summarise vast amounts of information quickly. In the past, frequency scaling was relied upon to push application throughput. ...
La trompa d'aigua o trompa dels Pirineus és el giny hidropneumàtic pel qual s'introduïa aire al forn en el procediment català d'obtenció directa del ferro a partir dels seus minerals, o de la Farga Catalana. En aquest ...
Ens proposem fer girar tubs de material conductor (coure o alumini) de diferents llargades i diàmetres. Aquest tub que hom vol fer girar és el secundari d'una màquina elèctrica d'inducció, i actua de rotor o part ...
Titanium (Ti) and its alloys are currently the materials chosen for many dental applications, mainly due to their optimum biocompatibility and excellent mechanical properties. Despite the success rates of dental implants, ...
L'estudi del senyal electrocardiogràfic (ECG) obtingut mitjançant elèctrodes de superfície és una prova mèdica freqüent que té una gran significació en el diagnòstic de l'activitat cardíaca. <br/>Des de la incorporació ...
The nowcasting of rainfall based on the extrapolation of the radar precipitation field is a common technique used in different operational and research centers. However, this deterministic forecasting technique is subject ...
This doctoral thesis is focused on what nowadays is known as the Mesoamerica Project (MP). The Integration and Development Mesoamerica Project arises due to the need not only to the regional integration but also to the ...
The impact of work when constructing a building between party walls is always a concern for the adjoining residents. The buildings are subject to more than just the impact of the vibrations caused by the use of machinery. ...
