    • Engineering patterns of wrinkles and bubbles in supported graphene through modeling and simulation 

      Zhang, Kuang (Universitat Politècnica de Catalunya, 2015-06-10)
      Tesi
      Accés obert
      Graphene deposited on a substrate often exhibits out-of-plane deformations with different features and origins. Networks of localized wrinkles have been observed in graphene synthesized through CVD, as a result of compressive ...

    • Machine learning in multiscale modeling and simulations of molecular systems 

      Hashemian, Behrooz (Universitat Politècnica de Catalunya, 2015-05-08)
      Tesi
      Accés obert
      Collective variables (CVs) are low-dimensional representations of the state of a complex system, which help us rationalize molecular conformations and sample free energy landscapes with molecular dynamics simulations. ...

    • Estimación bayesiana de cópulas extremales en procesos de Poisson 

      Ortego Martínez, María Isabel (Universitat Politècnica de Catalunya, 2015-02-04)
      Tesi
      Accés obert
      The estimation of occurrence probabilities of extremal quantities is essential in the study of hazards associated with natural phenomena. The extremal quantities of interest usually correspond to phenomena characterized ...

    • Decomposition techniques for computational limit analysis 

      Rabiei, Nima (Universitat Politècnica de Catalunya, 2014-10-27)
      Tesi
      Accés obert
      Limit analysis is relevant in many practical engineering areas such as the design of mechanical structure or the analysis of soil mechanics. The theory of limit analysis assumes a rigid, perfectly-plastic material to model ...

    • The inverse problem on finite networks 

      Arauz Lombardía, Cristina (Universitat Politècnica de Catalunya, 2014-06-19)
      Tesi
      Accés obert
      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 ...

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

      Gargallo Peiró, Abel (Universitat Politècnica de Catalunya, 2014-07-25)
      Tesi
      Accés obert
      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 ...

    • Continuous-discontinuous modelling for quasi-brittle failure: propagating cracks in a regularised bulk 

      Tamayo Mas, Elena (Universitat Politècnica de Catalunya, 2013-12-05)
      Tesi
      Accés obert
      A new strategy to describe failure of quasi-brittle materials -concrete, for example- is presented. Traditionally, numerical simulation of quasi-brittle failure has been tackled from two different points of view: damage ...

    • Efficient models for building acoustics : combining deterministic and statistical methods 

      Díaz Cereceda, Cristina (Universitat Politècnica de Catalunya, 2013-11-15)
      Tesi
      Accés obert
      Modelling vibroacoustic problems in the field of building design is a challenging problem due to the large size of the domains and the wide frequency range required by regulations. Standard numerical techniques, for instance ...

    • On the structure of graphs without short cycles 

      Salas Piñón, Julián (Universitat Politècnica de Catalunya, 2012-12-20)
      Tesi
      Accés obert
      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 ...

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

      Rahmi, Mohammad (Universitat Politècnica de Catalunya, 2013-04-09)
      Tesi
      Accés obert
      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 ...
