Acknowledgements
In first place, I would like to express my gratitude to my thesis advisors,
Dr. Albert Turon and Dr. Josep Costa. Their wise advice in our many
profitable discussions has been one of the cornerstones of this thesis, but
even more valuable has been the trusting and collaborative treating they
have offered me. I also acknowledge the AMADE research group for giving
me the chance to collaborate in many research projects during these years
and for setting up a rich environment for the development of this thesis.
During the development of this Ph.D. thesis, I have been given the op-
portunity to perform two research stays. I would like to acknowledge Dr.
Frank A. Leone and Dr. Carlos G. D´avila from NASA Langley Research
Center (Hampton, VA, USA) and Dr. Joris J. C. Remmers from the Eind-
hoven University of Technology (Eindhoven, The Netherlands) for giving
me the opportunity to carry out these research stays and enriching the
content of this thesis with useful discussions.
No vull deixar d’agrair l’amistat i el suport rebut per part dels meus
companys del grup de recerca AMADE. El seu tracte afable i proper acom-
panyat d’un gran sentit de l’humor (cadascu´ a la seva manera, aix`o s´ı) han
fet que aquest cam´ı hagi estat ple de bons moments dels quals en guardar´e
sempre un gran record.
El meu agra¨ıment m´es profund el dedico a la meva fam´ılia i amics.
Amb tots ells he tingut la sort de gaudir de magn´ıfiques estones i sentir-me
recolzatentotmoment. Enespecial,vullagrairlapaci`enciaielsuportdela
meva dona, l’Alba, qui t´e la virtut, per a mi inprescindible, de dotar-me de
confian¸ca en tot allo` que faig. Tamb´e vull agrair al meu germa` A`lex la seva

estima i els bons moments que m’ha fet passar des de ben petit, aix´ı com
al meu oncle Joan, per esperonar-me en tot moment a seguir endavant en
aquest cam´ı. Tinc clar que mai no podr´e agrair prou el suport que sempre
m’han ofert els meus pares Antoni i Ma Carmen, aix´ı com els valors que
han sabut inculcar-me i que conformen la persona que so´c avui. L’orgull
que senten pel que faig aquestes poques - pero` imprescindibles - persones
´es un dels factors que m´es em motiven a continuar endavant. Finalment,
vull recordar en aquestes l´ınies i expressar el meu agra¨ıment a la meva a`via
Pepita. La seva ensenyanc¸a esta` reflectida en aquesta tesi, i el record dels
seus consells de ben segur que romandr`a en tots aquells que vam tenir el
plaer de gaudir-ne.

The work contained in this Ph.D. thesis was conducted in the AMADE
researchgroup(DepartmentofMechanicalEngineeringandIndustrialCon-
struction, University of Girona, Spain). The thesis was carried out under
the grant AP2010-0977 from the FPU program from the Spanish Ministe-
rio de Educacio´n, Cultura y Deporte and partially funded by the Spanish
Government through the Ministerio de Econom´ıa y Competitividad under
the contracts DPI2012-34465 and MAT2012-37552-C03-03.
Part of the research presented in this thesis was developed during the
Ph.D. candidate’s stay at the NASA Langley Research Center (Hampton,
VA, United States of America) and in the Eindhoven University of Tech-
nology (Eindhoven, The Netherlands), which were respectively funded by
AMADE research group of the University of Girona and the Spanish Min-
isterio de Educacio´n, Cultura y Deporte through the grant EST13/00902.
