Casas Prat, Mercè (Data de defensa: 2014-01-20)
Climate change is a hot research topic due to the consequent impacts on our environment in the near future. The last report of the International Panel on Climate Change' the leading international body ...
Núñez González, Francisco (Data de defensa: 2012-07-20)
In this thesis, the interaction between flow and sediment in alluvial channels is studied from an empirical approach, for conditions close or pertaining to supercritical flow, and for four types of ...
Ritter, Josias Manuel Gisbert (Data de defensa: 2021-07-16)
Flash floods are one of the most devastating natural hazards, claiming numerous lives and tremendous economic losses. One of the main reasons for their catastrophic potential is the limited time available ...
Abdollahi, Amir (Data de defensa: 2012-10-18)
The unique electro-mechanical coupling properties of ferroelectrics make them ideal materials for use in micro-devices as sensors, actuators and transducers. Nevertheless, because of the intrinsic ...
Planas Badenas, Ramon (Data de defensa: 2013-11-25)
Magnetohydrodynamics (MHD) is the physics branch that studies electrically conducting fluids under external magnetic fields. This thesis deals with the numerical approximation using stabilized finite ...
Espinoza Román, Héctor Gabriel (Data de defensa: 2015-05-08)
The present work is a compilation of the research produced in the field of wave propagation modeling. It contains in-depth analysis of stability, convergence, dispersion and dissipation of spatial, ...
Khadivipanah, Peiman (Data de defensa: 2022-02-03)
The main objective of this thesis is to describe and implement a rate-dependent (viscoplastic) constitutive equations for copper based canister using a single internal state variable and use it for ...
Barbat Vlad, Gabriel (Data de defensa: 2021-02-11)
The numerical modelling of fracture has been an active topic of research for over five decades. Most of the approaches employed rely on the use of the Finite Element Method, which has shown to be an ...
Avila, Matías (Data de defensa: 2012-11-16)
The general description of a fluid flow involves the solution of the compressible Navier-Stokes equations, a very complex problem whose mathematical structure is not well understood. It is widely accepted ...
Reyes Sotomayor, Ricardo (Data de defensa: 2020-03-23)
This thesis presents the a stabilized projection-based Reduced Order Model (ROM) formulation in low speed fluid flows using a Variational Multi-Scale (VMS) approach. To develop this formulation we use ...
