Simulation tools for biomechanical applications with PGD-based reduced order models
(Universitat Politècnica de Catalunya, 2018-03-12)
Tesi
Accés obertNumerical simulation tools are generally used in all modern engineering fields, especially those having difficulties in performing large number of practical experiments, such as biomechanics. Among the computational methods, ... -
Spontaneous parametric down-conversion sources for generation of atom-resonant quantum light
(Universitat Politècnica de Catalunya, 2018-03-19)
Tesi
Accés obertThis thesis studies different designs of optical parametric oscillators as sources of atom-resonant quantum light resonant with the rubidium D1 line.We analyze the mode structure and filtering techniques in a conventional ... -
Fluid-electro-mechanical model of the human heart for supercomputers
(Universitat Politècnica de Catalunya, 2018-03-22)
Tesi
Accés obertThe heart is a complex system. From the transmembrane cell activity to the spatial organization in helicoidal fibers, it includes several spatial and temporal scales. The heart muscle is surrounded by two main tissues that ... -
Dynamic modelling and control schemes for current-source resonant converters
(Universitat Politècnica de Catalunya, 2018-10-09)
Tesi
Accés obertThis thesis focuses on the control methods applied to current source resonant converters, especially in two different applications of switching power supplies and wire-less power transfer systems. In fact, the existing ... -

Tesi
Accés obertThis work has focused on the study and development of hierarchically, flexible electrodes and lightweight capacitor using as a source of flexibility. the y-polyglutamic acid (y-PGA) and as an electroactive polymer the ... -
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 ... -
Investigation of continuous-wave range-resolved lidar systems for gas detection and concentration measurement
(Universitat Politècnica de Catalunya, 2011-07-27)
Tesi
Accés obertThe techniques for detection of the atmosphere constituents and their distribution in the space have evolved in the last years driven by needs in the environmental, meteorological and climate science fields and backed by ... -
Assessment of dynamic aerosol-radiation interaction in atmospheric models
(Universitat Politècnica de Catalunya, 2018-03-07)
Tesi
Accés obertIn this thesis an assessment of the parameterization of the Aerosol-Radiation Interaction (ARI) in online integrated meteorology-chemistry models has been conducted. The model estimates of ARI radiative effects are still ... -
Comparison and coupling of continuous and hybridizable discontinuous Galerkin methods : application to multi-physics problems
(Universitat Politècnica de Catalunya, 2018-03-21)
Tesi
Accés obertThis thesis proposes a coupled continuous and hybridizable discontinuous Galerkin formulation to solve conjugate heat transfer problems. This model is then used to find the thermal response of Glass Fiber Reinforced Polymer ... -
