    Nonlinear control of uncertain systems: Some application-oriented issues 

    Pozo Montero, Francesc (Date of defense: 2005-01-20)

    L'anàlisi i el control de sistemes amb incerteses són un dels problemes més interessants en l'àmbit de la teoria de control. En les últimes dues dècades hi ha hagut un augment important en la recerca dedicada a resoldre ...

    Numerical modelling of complex geomechanical problems 

    Pérez Foguet, Agustí (Date of defense: 2000-12-01)

    La tesis se centra en el desarrollo de técnicas numéricas específicas para la resolución de problemas de mecánica de sólidos, tomando como referencia aquellos que involucran geomateriales (suelos, rocas, materiales ...

    On the consistency of hysteresis models 

    Fuad Mohammad Naser, Mohammad (Date of defense: 2014-01-30)

    Hysteresis is a nonlinear behavior encountered in a wide variety of processes including biology, optics, electronics, ferroelectricity, magnetism, mechanics, structures, among other areas. One of the main features of ...

    On the structure of graphs without short cycles 

    Salas Piñón, Julián (Date of defense: 2012-12-20)

    The objective of this thesis is to study cages, constructions and properties of such families of graphs. For this, the study of graphs without short cycles plays a fundamental role in order to develop some knowledge on ...

    Point-set manifold processing for computational mechanics: thin shells, reduced order modeling, cell motility and molecular conformations 

    Millán, Daniel (Date of defense: 2012-11-12)

    In many applications, one would like to perform calculations on smooth manifolds of dimension d embedded in a high-dimensional space of dimension D. Often, a continuous description of such manifold is not known, and instead ...

    Shape dynamics and lipid hydrodynamics of bilayer membranes: modeling, simulation and experiments 

    Rahmi, Mohammad (Date of defense: 2013-04-09)

    Biological membranes are continuously brought out of equilibrium, as they shape organelles, package and transport cargo, or respond to external actions. The dynamics of lipid membranes are very complex due to the tight ...

    Shock capturing for discontinuous Galerkin methods 

    Casoni Rero, Eva (Date of defense: 2011-10-14)

    Aquesta tesi doctoral proposa formulacions de Galerkin Discontinu (DG) d’alt ordre per la captura de shocks, obtenint alhora solucions altament precises per problemes de flux compressible. En les últimes dècades, la ...

    Sobre l'ordenació de les arrels reals de les derivades de polinomis a coeficients reals. 

    Rubió Massegú, Josep (Date of defense: 2005-02-10)

    Alguns problemes clàssics sobre teoria analítica de polinomis estan relacionats amb un problema més general: determinar com estan ordenades les arrels reals d'un polinomi a coeficients reals i les arrels reals de totes les ...

    The inverse problem on finite networks 

    Araúz Lombardía, Cristina (Date of defense: 2014-06-19)

    The aim of this thesis is to contribute to the field of discrete boundary value problems on finite networks. Boundary value problems have been considered both on the continuum and on the discrete fields. Despite working ...

    Una metodología general para optimización estructural en diseño asistido por ordenador 

    Navarrina Martínez, Fermín (Date of defense: 1987-05-20)

    En aquest treball s'analitza el procés de disseny des d'una perspectiva metodològica general. Aquest enfocament condueix de forma natural al concepte de disseny òptim i a la seva formulació com un problema de Programació ...

    Validation and generation of curved meshes for high-order unstructured methods 

    Gargallo Peiró, Abel (Date of defense: 2014-07-25)

    In this thesis, a new framework to validate and generate curved high-order meshes for complex models is proposed. The main application of the proposed framework is to generate curved meshes that are suitable for finite ...
