I would like to thank my advisors Juan F. Llamas and Antonio Hurtado for providing
me the opportunity to start my Ph.D. thesis in Universidad Politécnica de Madrid.
Although they always being busy, they could find time to offer me professional and
financial support.
I would like to express my sincerely appreciation to my tutors ? Sonsoles and
Fernando in CIEMAT. I spent majority time in CIEMAT with them, they were not
only my advisor who helped me to solve the academic issues, to modify my papers
and posters that enlightening my academic career. But also they gave me lots of
supports in normal life, they helped me finished almost all administrative papers that
could let me do not bothering by these stuffs. As a foreigner, no matter how little thing
is, they explained many times until I understand completely. Muchas gracias a
ustedes
