Application of multibody dynamics techniques to the analysis of human gait

Pàmies Vilà, Rosa (Date of defense: 2012-12-21)

La tesi que es presenta tracta l’estudi cinemàtic i dinàmic de la marxa humana mitjançant tècniques de dinàmica de sistemes multisòlid. Per a aquest propòsit, s’utilitzen dos models biomecànics: un model pla format per 11 ...

Contribució a l'estudi dels conjunts extensionals de les relacions d'indistingibilitat i la seva aplicació a la representació d'imatges de ressonància magnètica

Mattioli Aramburu, Gabriel (Date of defense: 2016-03-17)

This thesis can be summarized in the following sentence: All scientific models, for instance structural atlases of brain MRI, can be read in terms of fuzzy extensional sets. The work done in this doctoral thesis backs up ...

Contribution to prognostics and health management of complex systems. Application to energy systems

Al Mohamad, Ahmad (Date of defense: 2021-10-22)

(English) This thesis presents contributions to model-based Prognostics and Health Management (PHM) for online Remaining Useful Life (RUL) forecasting of degraded systems. The major issue in such a prognostics approach is ...

Development of nonlinear techniques based on time-frequency representation and information theory for the analysis of EEG signals to assess different states of consciousness

Melia, Umberto (Date of defense: 2014-12-03)

Electroencephalogram (EEG) recordings provide insight into the changes in brain activity associated with various states of anesthesia, epilepsy, brain attentiveness, sleep disorders, brain disorders, etc. EEG's are complex ...

Identifiability and calibration of water network models

Pérez Magrané, Ramon (Date of defense: 2003-07-21)

El control i supervisió de processos es basa generalment en la utilització de models. Models que han de ser tan acurats com sigui possible. Processos complexes com les xarxes de distribució d'aigua no escapen d'aquesta ...

Interacción en sistemas biológicos mediante nuevos índices basados en la dinámica no lineal

Alonso López, Joan Francesc (Date of defense: 2011-09-29)

Most biological systems are complex and consist of several interconnected parts whose links can contain additional information which can be hidden from the observer. As a result of the interactions between elements, emergent ...

Mathematical models and multiscale simulations of cellular secretion processes

González-Vélez, Virginia (Date of defense: 2011-07-26)

Exocytosis is the cellular process whereby a product such as a hormone or a neurotransmitter is released as a response to stimulation. There are a lot of exocytotic cells in mammals, and each cell type has their specific ...

Methods and models in signal processing for gait analysis using waist-worn accelerometer : a contribution to Parkinson’s disease

Sayeed, Taufique (Date of defense: 2015-07-16)

Parkinson's disease (PD) is a neurodegenerative disease that predominantly alters patients' motor performance and compromises the speed, the automaticity and fluidity of natural movements. After some years, patients fluctuate ...

Modeling and control for a fuel cell system

Xing, Yashan (Date of defense: 2021-07-01)

(English) Fuel cells are electrochemical devices to covert hydrogen and oxygen into electrical energy and heat. However, the degradation during the operation can reduce a fuel cell lifetime which is the major obstacle for ...

Multiple cue integration for robust tracking in dynamic environments: application to video relighting

Moreno Noguer, Francesc (Date of defense: 2005-09-01)

L'anàlisi de moviment i seguiment d'objectes ha estat un dels pricipals focus d'atenció en la comunitat de visió per computador durant les dues darreres dècades. L'interès per aquesta àrea de recerca resideix en el seu ...
