Fernández Canti, Rosa Ma. (Date of defense: 2013-02-07)
In the Control Engineering field, the so-called Robust Identification techniques deal with the problem of obtaining not only a nominal model of the plant, but also an estimate of the uncertainty associated to the nominal ...
Salvador, Amaia (Date of defense: 2019-06-27)
In the past decade, deep neural networks have revolutionized computer vision. High performing deep neural architectures trained for visual recognition tasks have pushed the field towards methods relying on learned image ...
Kumar, Dhiraj (Date of defense: 2012-07-16)
The increasing need for range-resolved aerosol and water-vapour atmospheric observation networks worldwide has given rise to multi-spectral LIDARs (Light Detection and Ranging, a synonym of laser radar) as advanced remote ...
Alonso Arroyo, Alberto (Date of defense: 2016-11-10)
This PhD thesis researches the use of passive remote sensing techniques using signals transmitted from the navigation satellites (GNSS) in order to retrieve different geophysical parameters. The thesis consists of two ...
Cardoso Duarte, Amanda (Date of defense: 2022-06-27)
Signed languages are complete and natural languages used as the first or preferred mode of communication by millions of people worldwide. However, they, unfortunately, continue to be marginalized languages. Designing, ...
Amézaga, Adrià (Date of defense: 2020-11-25)
Synthetic Aperture Radar (SAR) has proven a valuable tool in the monitoring of the Earth, either at a global or local scales. SAR is a coherent radar system able to image extended areas with high resolution, and finds ...
Nadal Reixats, Laia (Date of defense: 2014-11-21)
Due to the increasing global IP traffic and the exponential growing demand for broadband services, optical networks are experimenting significant changes. Advanced modulation formats are being implemented at the Digital ...
Ardanuy Della, Antoni (Date of defense: 2020-12-14)
This thesis aims at exploring the limits of low peak-power, low-cost, all-semiconductor, compact lidars (laser radars) for range-resolved remote sensing of atmospheric aerosols and clouds. The systems investigated are based ...
Oikonomakou, Maria (Date of defense: 2019-04-10)
During the recent years, a huge augmentation of the data traffic volume has been noticed, while a further steep increase is expected in the following years. As a result, questions have been raised over the years about the ...
Espinosa Duró, Virginia (Date of defense: 2013-06-14)
Face recognition (FR) has been extensively studied, due to both scientific fundamental challenges and current and potential applications where human identification is needed. FR systems have the benefits of their non ...
Egido Egido, Alejandro (Date of defense: 2013-07-05)
Soil moisture and vegetation biomass are two essential parameters from a scienti c and economical point of view. On one hand, they are key for the understanding of the hydrological and carbon cycle. On the other hand, soil ...
Garrido Ostermann, Luís (Date of defense: 2002-06-14)
Este trabajo estudia la utilidad de representaciones jerárquicas basadas en regiones para el procesado de imagen y de secuencias de vídeo. Las representaciones basadas en regiones ofrecen una forma de realizar un primer ...
Devanthéry Arasa, Núria (Date of defense: 2014-10-31)
Persistent Scatterer Interferometry (PSI) is a group of advanced differential interferometric SAR techniques that are used to measure and monitor terrain deformation. Different PSI techniques have been proposed in the last ...
Suau Cuadros, Xavier (Date of defense: 2013-12-04)
