UAV perception for safe flight under physical interaction
The control of autonomous flying vehicles with navigation purposes is a challenging task. Complexity arises mainly due to the non-linearity and uncertainty inherently present in the flight mechanics and aircraft-air ...
Ubiquitin ligases involved in the regulation of Snail1
Epithelial to mesenchymal transition (EMT) is a process by which epithelial cells acquire a mesenchymal phenotype. It is characterized by the down-regulation of the adherens junction protein E-cadherin, and it is important ...
Ubiquitous supercomputing : design and development of enabling technologies for multi-robot systems rethinking supercomputing
Supercomputing, also known as High Performance Computing (HPC), is almost everywhere (ubiquitous), from the small widget in your phone telling you that today will be a sunny day, up to the next great contribution to the ...
“UCI extendida” Seguimiento de los pacientes críticos al alta del servicio de medicina intensiva del Hospital del Mar
La mejora en la atención y el cuidado del paciente crítico es un tema que al médico intensivista preocupa, con el objetivo de aumentar la efectividad y eficacia en el manejo de estos pacientes han surgido distintos programas ...
Ulrich bundles and varieties of wild representation type
The subject of this thesis lies at the junction of mainly three topics: construction of large families of Arithmetically Cohen-Macaulay indecomposable vector bundles on a given projective variety X, the shape (i.e, the ...
Ultra low-power, high-performance accelerator for speech recognition
Automatic Speech Recognition (ASR) is undoubtedly one of the most important and interesting applications in the cutting-edge era of Deep-learning deployment, especially in the mobile segment. Fast and accurate ASR comes ...
Ultra-endurance triathlon: heart rate-based intensity profile, energy balance, muscle damage and race performance
This thesis presents the results of two research studies related to the physiological demands, the energy balance and the muscle damage induced by an ultra-endurance triathlon. The first study of this thesis examined the ...
Ultra-high pressure homogenisation of milk: effects on cheese-making
El objetivo de la tesis fue evaluar la aptitud tecnológica de la leche tratada por ultra alta presión homogenización (UHPH) como alternativa a la pasteurización en el tratamiento de higienización de la leche para la obtención ...
Ultra-high resolution environmental and climatic reconstruction using oxygen and carbon isotopes of diatom frustules
Calcareous microfossils are not always present in marine or lacustrine sediments owing to unfavourable ecological or post-depositional conditions. These non-carbonated sediments sometimes contain abundant biogenic silica, ...
Ultra-low power circuits based on tunnel FETs for energy harvesting applications
There has been a tremendous evolution in integrated circuit technology in the past decades. With the scaling of complementary metal-oxide-semiconductor (CMOS) transistors, faster, less power consuming and more complex chips ...
