Nevot Cercós, Javier (Date of defense: 2000-03-17)
En la presente tesis se desarrolla un sistema de control de la mezcla de aire y gasolina en un motor alternativo de cuatro tiempos, basado en redes neuronales. Para que el catalizador logre un grado de depuración aceptable ...
Llusà Serra, Aleix (Date of defense: 2015-12-04)
Nowadays, it is possible to acquire a huge amount of data, mainly due to the fact that it is easy to build monitoring systems together with big sensor networks. However, data has to be managed accordingly, which is not so ...
Navarro López, Eva Maria (Date of defense: 2002-06-28)
El propósito de la presente tesis es el estudio de la disipatividad en sistemas no lineales discretos. Dicho trabajo de investigación presenta nuevas contribuciones en la teoría de control no lineal discreto basado en ...
Rojas, Nicolàs (Date of defense: 2012-06-20)
This thesis addresses the kinematic analysis of mechanisms, in particular, the position analysis of kinematic chains, or linkages, that is, mechanisms with rigid bodies (links) interconnected by kinematic pairs (joints). ...
Javalera Rincón, Valeria (Date of defense: 2016-04-07)
This thesis describes a methodology to deal with the interaction between MPC controllers in a distributed MPC architecture. This approach combines ideas from Distributed Artificial Intelligence (DAI) and Reinforcement ...
Villamizar Vergel, Michael Alejandro (Date of defense: 2012-09-18)
La visión por computador y más específicamente el reconocimiento de objetos han demostrado en los últimos años un impresionante progreso que ha llevado a la aparición de nuevas y útiles tecnologías que facilitan nuestras ...
Igelmo Ganzo, Manuel (Date of defense: 2016-01-28)
The first objective proposed in the research of this thesis was the select and develop a (preferably simple) model for graphs, thus, the results obtained through the model may be extrapolated to the modeled objects: graphs. ...
Fargas Marquès, Andreu (Date of defense: 2016-01-22)
Plenty of Micro-electro-mechanical Systems (MEMS) devices are actuated using electrostatic forces, and specially, parallel-plate actuators are extensively used, due to the simplicity of their design. Nevertheless, ...
Trulls Fortuny, Eduard (Date of defense: 2015-02-20)
Local features have become an essential tool in visual recognition. Much of the progress in computer vision over the past decade has built on simple, local representations such as SIFT or HOG. SIFT in particular shifted ...
Aguilar Castillo, Wilbert Geovanny (Date of defense: 2015-09-04)
Micro Aerial Vehicles (MAVs), a subset of Unmanned Aerial Vehicles (UAVs), also known as drones, are becoming popular for several applications and gaining interest due to advantages as manufacturing and maintenance cost, ...
Castillo Pérez, Esteban del (Date of defense: 2013-09-30)
Desde hace varias décadas los robots industriales han demostrado su eficiencia para tareas desarrolladas en entornos perfectamente conocidos. No obstante, surgen importantes complicaciones operativas en entornos limitadamente ...
Avilés Rivero, Angélica Ivone (Date of defense: 2017-05-18)
Estimating and understanding motion from an image sequence is a central topic in computer vision. The high interest in this topic is because we are living in a world where many events that occur in the environment are ...
