Riba Porras, Sergi (Data de defensa: 2022-06-14)
Over the last 40 years, in Europe in general and in many mountainous regions in particular, there have been major instances of severe flood episodes (more than 100) which have resulted in more than 700 deaths and billions ...
Regalado López, Francisco Javier (Data de defensa: 2022-06-22)
The constant and rapid population growth goes hand in hand with an increased demand for services that governments have the duty to satisfy with the problem of limited financial resources. Transport infrastructure is one ...
Valdés Alonzo, Gabriel Rolando (Data de defensa: 2022-06-03)
Identifying the constitutive relations of materials is an essential task to understand their behavior. Classical methods like testing can be effective in understanding these relationships, but introducing models can lead ...
Cavaliere, Fabiola (Data de defensa: 2022-04-06)
In order to be worldwide competitive, the automotive industry is constantly challenged to produce higher quality vehicles in the shortest time possible and with the minimum costs of production. Most of the problems with ...
Delgadillo Ayala, Rick Milton (Data de defensa: 2022-03-23)
In recent years the scientific community has been developing new techniques in structural health monitoring (SHM) to identify the damages in civil structures specially in bridges. The bridge health monitoring (BHM) systems ...
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 modelling disposal schemes ...
Hashemi, Mohammad Reza (Data de defensa: 2022-02-22)
In numerous applications, two-phase liquid-gas transport at sub-millimeter length scales plays a substantial role in the determination of the behavior of the system at hand. As its main application, the present work focuses ...
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 for precautionary ...
Palacios Pierluissi, Andrea Viviana (Data de defensa: 2021-09-16)
Seawater intrusion (SWI) consists in the movement of seawater (SW) into freshwater (FW) aquifers, contaminating drinking water resources. SWI, along with the parallel reduction of Submarine Groundwater Discharge may lead ...
