Taghvaee, Hamidreza (Date of defense: 2021-07-21)
Sixth Generation (6G) of wireless networks will be even more heterogeneous and dense as compared to Fifth Generation (5G) and other legacy networks. Thus, the 6G architecture will need to be adapted to serve the ever-evolving ...
Apolonia, Nuno (Date of defense: 2018-09-21)
Internet coverage in the world is still weak and local communities are required to come together and build their own network infrastructures. People collaborate for the common goal of accessing the Internet and cloud ...
Gómez Crespo, Constantino (Date of defense: 2022-05-23)
The landscape of High Performance Computing (HPC) system architectures keeps expanding with new technologies and increased complexity. To improve the efficiency of next-generation compute devices, architects are looking ...
Ferrer Cid, Pau (Date of defense: 2023-05-08)
(English) Nowadays, authorities monitor the concentrations of regulated air pollutants in order to assist in decision-making processes, e.g., for the implementation of traffic restrictions, and mitigate the effects of air ...
Maroñas, Marcos (Date of defense: 2021-02-17)
High Performance Computing (HPC) systems have been evolving over time to adapt to the scientific community requirements. We are currently approaching to the Exascale era. Exascale systems will incorporate a large number ...
Ratković, Ivan (Date of defense: 2016-12-14)
Vector processors are a very promising solution for mobile devices and servers due to their inherently energy-efficient way of exploiting datalevel parallelism. While vector processors succeeded in the high performance ...
Milutinovic, Suzana (Date of defense: 2019-12-18)
Over the last years, we are witnessing the steady and rapid growth of Critica! Real-Time Embedded Systems (CRTES) industries, such as automotive and aerospace. Many of the increasingly-complex CRTES' functionalities that ...
Gelado Fernández, Isaac (Date of defense: 2010-07-02)
