Beyond the classical Stefan problem
(Universitat Politècnica de Catalunya, 2014-07-18)
Tesi
Accés obertIn 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
(Universitat Politècnica de Catalunya, 2016-07)
Projecte Final de Màster Oficial
Accés obertThe 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 ... -
Diffusion processes and nanoparticle growth
(Universitat Politècnica de Catalunya, 2020-09-15)
Tesi
Accés obertEs conocido que muchas propiedades de las nanopartículas, como la luminiscencia, la fotoestabilidad, la eficiencia de la radiación óptica y las propiedades eléctricas, dependen del tamaño. Por lo tanto, la capacidad de ... -
Heat transfer at the nanoscale : The hyperbolic heat equation
(Universitat Politècnica de Catalunya, 2015-07)
Treball Final de Grau
Accés obertThe 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
(Universitat Politècnica de Catalunya, 2016-01)
Treball Final de Grau
Accés restringit per decisió de l'autorNowadays, 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 carbon capture process by sorption
(Universitat Politècnica de Catalunya, 2022-01)
Treball Final de Grau
Accés obertConcern for carbon dioxide emissions have been growing considerably during the last years and this has motivated research in topics like carbon capture. Carbon capture consists in capturing the carbon dioxide that is ... -
Mathematical modelling of diffusion processes at the nanoscale
(Universitat Politècnica de Catalunya, 2018-03-16)
Tesi
Accés obertIn 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-classical thermal transport and phase change at the nanoscale
(Universitat Politècnica de Catalunya, 2019-07-12)
Tesi
Accés obertFor 200 years, Fourier’s law has been used to describe heat transfer with excellent results. However, as technology advances, more and more situations arise where heat conduction is not well described by the classical ... -
Non-Fourier heat conduction: The Maxwell-Cattaneo equations
(Universitat Politècnica de Catalunya, 2015-10)
Projecte Final de Màster Oficial
Accés obertWe 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
(Universitat Politècnica de Catalunya, 2012-05)
Projecte Final de Màster Oficial
Accés restringit per decisió de l'autorThe 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 ...
