The aim of this thesis is two-fold. First it provides a general methodology for applying image deconvolution to wide-field CCD imagery. Second, two new CCD observational techniques and two data analysis ...
Bosch i Ramon, Valentí (Date of defense: 2006-04-27)
Microquasars are X-ray binary systems that present relativistic radio jets.<br/>These systems consist on a normal star and a compact object, where the latter accretes matter from the former powering the ...

La predicció de l'índex UV consisteix a determinar la irradiància biològicament efectiva que incidirà en un temps posterior a partir del coneixement dels factors que hi intervenen: l'ozó, l'angle zenital, ...
Àgueda Costafreda, Neus (Date of defense: 2008-04-28)
We have developed a Monte Carlo model to simulate the transport of solar near-relativistic (NR; 30-300 keV) electrons along the interplanetary magnetic field (IMF), including adiabatic focusing, pitch-angle ...
