• Beyond the classical Stefan problem 

    Font Martínez, Francesc (Universitat Politècnica de Catalunya, 2014-07-18)
    Tesi
    Accés obert
    In this thesis we develop and analyse mathematical models describing phase change phenomena linked with novel technological applications. The models are based on modifications to standard phase change theory. The mathematical ...
  • Comparison of a size-dependent model for the latent heat of small tin nanoparticles 

    González Esteve, Adrià (Universitat Politècnica de Catalunya, 2016-07)
    Projecte Final de Màster Oficial
    Accés obert
    The classical formulation for the Stefan problem at the nanoscale does not work because the melting temperature and the effective latent heat decrease with the nanoparticle size. In this work, a model for the effective ...
  • Heat transfer at the nanoscale : The hyperbolic heat equation 

    Irastorza Ugalde, Beñat (Universitat Politècnica de Catalunya, 2015-07)
    Treball Final de Grau
    Accés obert
    The interest of taking technology to increasingly small scales has required great changes and advances in science. In particular, the well-known Fourier's law (very useful in large scales) has proved to be not accurate ...
  • Image classification for early detection of lung cancer 

    Morales Muñoz, Maria de Araceli (Universitat Politècnica de Catalunya, 2016-01)
    Treball Final de Grau
    Accés restringit per decisió de l'autor
    Nowadays, only 10 - 15% of people diagnosed with lung cancer survive more than 5 years after the diagnostic. The main cause is the delay in detecting it. One way of early detecting nodules is to use a system over chest ...
  • Mathematical modelling of diffusion processes at the nanoscale 

    Ribera Ponsa, Helena (Universitat Politècnica de Catalunya, 2018-03-16)
    Tesi
    Accés obert
    In this thesis we study diffusion processes of nanoparticle evolution and develop appropriate models with the aim of being able to optimise their functions according to the needs of industry. Two distinct diffusion processes ...
  • Non-Fourier heat conduction: The Maxwell-Cattaneo equations 

    Calvo Schwarzwälder, Marc (Universitat Politècnica de Catalunya, 2015-10)
    Projecte Final de Màster Oficial
    Accés obert
    We study the derivation, properties and solution methods of the classical and the hyperbolic heat transfer equations. Some results to approximate the hyperbolic model with the classical model for small values of the thermal ...
  • Study of the prognosis in the intensive care unit 

    Ribas Ripoll, Vicente Jorge (Universitat Politècnica de Catalunya, 2012-05)
    Projecte Final de Màster Oficial
    Accés restringit per decisió de l'autor
    The research reported in this document deals with the problem of Sepsis data analysis in general and, more specifically, with the problem of survival prediction for patients affected with Severe Sepsis. The tools at the ...
