    Gibert Gutiérrez, Ferran (Date of defense: 2016-02-23)

    The LISA Pathfinder project is an ESA/NASA technology demonstrator mission that must test the critical instrumentation required for a future space-borne gravitational wave observatory based on the LISA design. The satellite, ...

    Three-dimensional SPH simulations of the interaction between the nova ejecta and the companion star 

    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 ...

    Traffic synchronization with controlled time of arrival for cost-efficient trajectories in high-density terminal airspace 

    Sáez García, Raúl (Date of defense: 2021-10-01)

    The growth in air traffic has led to a continuously growing environmental sensitivity in aviation, encouraging the research into methods for achieving a greener air transportation. In this context, continuous descent ...

    Ubiquitous supercomputing : design and development of enabling technologies for multi-robot systems rethinking supercomputing 

    Camargo Forero, Leonardo (Date of defense: 2019-10-25)

    Supercomputing, also known as High Performance Computing (HPC), is almost everywhere (ubiquitous), from the small widget in your phone telling you that today will be a sunny day, up to the next great contribution to the ...
