Mestres Ridge, Marc (Date of defense: 2002-07-15)
Traditionally, the sea has been considered as the ultimate sink of most pollutions, due to its huge volume and assimilating capacities, and the coastal waters, because of their intermediate position between deep seas and ...
Figueira, Joana (Date of defense: 2023-05-31)
(English) Classical and Recurrent novae are thermonuclear explosions hosted by accreting white dwarfs in stellar binary systems. Material piles up on top of the white dwarf star under mildly degenerate conditions, driving ...
Coulson, Matthew John (Date of defense: 2021-12-13)
We consider some models of random graphs and directed graphs and investigate their behavior near thresholds for the appearance of certain types of connected components. Firstly, we look at the critical window for the ...
Geronta, Antigoni (Date of defense: 2019-07-17)
This thesis emanates from the premise that the impact of an architectural project is manifested not only in the organization of space and, by extension, in the social relationships established therein, but mainly in the ...
Safari, Alaleh (Date of defense: 2017-03-31)
Total hip replacement (THR) has been one of the most successful surgeries in the 21st century. Ultra-high-molecular-weight-polyethylene (UHMWPE) shows favorable mechanical and tribological properties when used as a bearing ...
Pagliazzi, Marco (Date of defense: 2019-10-04)
The non-invasive and, often, continuous measurement of the hemodynamics of the body, and for the main purposes of this thesis, the brain, is desired because both the instantaneous values and their changes over time constantly ...
Pallarés Valls, Oriol (Date of defense: 2016-11-30)
This thesis deals with the development of a time synchronization algorithm for underwater sensor networks. The ease of deployment and maintenance of wireless networks leaded this research to the use of an acoustic communication ...
Panić, Miloš (Date of defense: 2018-05-25)
Critical Real-Time Embedded Systems (CRTES) are in charge of controlling fundamental parts of embedded system, e.g. energy harvesting solar panels in satellites, steering and breaking in cars, or flight management systems ...
Serrano, Maria A. (Date of defense: 2019-03-13)
The recent technological advancements and market trends are causing an interesting phenomenon towards the convergence of the high-performance and the embedded computing domains. Critical real-time embedded systems are ...
Starnini, Michele (Date of defense: 2014-10-24)
The data revolution experienced by social science has revealed complex patterns of interactions in human dynamics, such as the heterogeneity and burstiness of social contacts. The recently uncovered temporal dimension of ...
Aghazadeh Dafsari, Seyed Rasoul (Date of defense: 2022-05-03)
Antenna array systems have a broad range of applications in radio frequency (RF) and ultra-wideband (UWB) communications to receive/transmit electromagnetic waves from/to the sky. They can enhance the amplitude of the input ...
Xing, Congcong (Date of defense: 2021-07-30)
The photocatalytic production of hydrogen from water and biomass derivatives such as ethanol, glycerol and sugars is a highly attractive strategy to generate environmentally benign hydrogen. Ethanol is more easily oxidized ...
