Aportes Metodológicos para el Estudio de los Entornos Alimentarios en Población Escolar
En su mayoría, las intervenciones para disminuir la prevalencia de la obesidad y promover la adopción de patrones de alimentación y hábitos saludables en población escolar, se han basado en incentivar cambios conductuales ...
Apoyo social percibido en pacientes con cáncer
Desde los inicios de la psico-oncología se propone un acercamiento holístico e integral para el tratamiento del cáncer, que se propicia desde el modelo bio-psico-social. La teoría del buffering-stress, entiende el ...
Appearance-based Loop Closure Detection and its Application to Topological Mapping and Image Mosaicing
Mapping and localization are two essential processes in autonomous mobile robotics since they are the basis of other higher level and more complex tasks, such as obstacle avoidance or path planning. Mapping is the process ...
Appearance-based mapping and localization using feature stability histograms for mobile robot navigation
This work proposes an appearance-based SLAM method whose main contribution is the Feature Stability Histogram (FSH). The FSH is built using a voting schema, if the feature is re-observed, it will be promoted; otherwise it ...
The appliance of the concept of sustainability in human resource management in the corporate sector in Germany
Decline of resources, increasing expectation of stakeholders and radical transparency imposed by new technologies urges multinational enterprises to define sustainability as an important driver, which affects Strategic and ...
Applicability of deterministic global optimization to the short-term hydrothermal coordination problem
Esta Tesis esta motivada por el interés en aplicar procedimientos de optimización global a problemas del mundo real. Para ello, nos hemos centrado en el problema de Coordinación Hidrotérmica de la Generación Eléctrica a ...
The applicability of in vitro models of the intestinal barrier for the risk assessment of engineered nanomaterials used as food additives
Los avances en el campo de la nanotecnología han permitido desarrollar una gran diversidad de nanomateriales sintetizados artificialmente (NMs), los cuales presentan nuevas y prometedoras aplicaciones en diversas industrias. ...
Applicability of microextraction techniques for the etermination of synthetic musk fragrances in environmental samples
Aquesta Tesi doctoral se centra en el desenvolupament de mètodes analítics alternatius, més respectuosos amb el medi ambient, per la determinació de fragàncies sintètiques en mostres mediambientals tals com aigües residuals, ...
Applicability of wireless injectable microstimulators based on volume conduction for high density neuromuscular stimulation
This thesis was conducted within the framework of the eAXON project that is aimed at developing injectable wireless sub-millimetric single-channel addressable microstimulators based on volume conduction called eAXONs ...
Application and use of quality metrics for the prediction of grasp success and evaluation of artificial hands
Artificial manipulation has been one of the main areas of interest in robotics for decades. Finding a proper grasp to seize objects and design robotic hands capable of such grasps are two of the main problems in such ...
An application framework for the systematic construction of multimedia-based Collaborative Complex Learning Resources
Aquest treball de tesi proposa aportar una infraestructura de programari per donar suport a nous tipus de metodologies i recursos d'aprenentatge col·laboratiu augmentats pedagògicament i a través d'una plataforma d'aplicació ...
Application of advanced mass spectrometric techniques for the identification, metabolic characterisation and toxicological analysis of new psychoactive substances
This Doctoral Thesis presents an in-depth investigation on NPS from the analytical chemistry point of view, being structured in three blocks. The first is focused on the analytical characterisation of different compounds, ...
Application of Advanced Oxidation Processes in the Reclamation of Wastewaters from the Oil & Gas Sector
Aquesta tesi s'emmarca dins de dos projectes relacionats amb la recuperació (tractament + reutilització) d'aigües residuals generades per la indústria de petroli i gas. L'objectiu del primer projecte va ser la reutilització ...
Application of analytical and chemometric methodologies to study complex bioanalytical processes involving DNA i-motif structures
The i-motif is a DNA structure formed by cytosine-rich sequences that consists of parallel- stranded duplexes held together by intercalated base pairs. The in vitro formation of this structure in DNA sequences corresponding ...
