If I had to choose only one person to thank for the support received during the preparation of this document, I would be committing a great injustice, since my path has been enlightened by different estimated collaborators. Nevertheless, I truly have a debt of gratitude with:Dr. Luis Sánchez de León, my dear colleague, because without his unwavering support, his natural born intellectual brilliance, and his complete dedication during these past long years of preparation, even under extremely difficult personal circumstances that still impress me, this work would not have been possible.Dr. José Manuel Vega, master, mentor, and top-class researcher, who provided an enormous support, with his expertise, mindset, generosity, and advice during the sometimes difficult, but still rewarding, elaboration of this thesis. He showed to me the way to follow, he took me under his wings during difficult moments, being a personal and academic reference, while sharing selflessly, even after extremely worrying health circumstances, his vast knowledge regarding the different topics treated in this document.Other brilliant colleagues at ETSIAE-UPM, like Dr. Ángel Velázquez and Dr. Francisco Sastre, have also contributed remarkably to the development of the proposed research line by showing innovative ways to improve results. They provided an unvaluable support during critical moments.And last, but not least, I must thank to the director of this thesis, Dr. José Luis Montañés, master, mentor, and friend since many years, his leading and focused technical approach, his clarity, his passion on everything he endeavors, his smart vision, his continuous support by being always accessible and the pilar upon everything was elevated, and the faith he inexplicably always had in me. I wish I could deserve one day just a fraction of it. He gave me the tools to achieve all the goals I had so far in my life, and he transmitted to me the respect and consideration for the Engineering, the Science, and for our Alma Mater.They are the model or, better said, the mirror in which I wish to contemplate myself in the future. As an engineer, and as a person.Climbing on their shoulders, I could see beyond.
