In the last decades, the development trends of high efficiency and compact electric drives on the motor side focused on Permanent Magnet Synchronous Machines (PMSMs) equipped with magnets based on the rare-earth elements. ...
Delgado, Laura (Date of defense: 2017-10-09)
En los últimos años muchas novas- ocho clásicas y dos recurrentes- han sido detectadas por Fermi/LAT a E$>$100 MeV. En la mayoría de los casos esta emisión se observa pronto después de la explosión, alrededor del máximo ...
Torres i Albà, Núria (Date of defense: 2019-10-14)
This thesis has as an objective the study of very energetic phenomena in the central regions of active galaxies. Intense star formation is triggered by mergers of galaxies, and the funneling of large quantities of gas ...
Munar i Adrover, Pere (Date of defense: 2014-03-28)
The high energy astrophysics, specifically the gamma-ray astrophysics, studies the processes that cannot be caused by hot matter but by other mechanisms colled non thermaland processes, which involve matter with energies ...
