Their invaluable expertise made me able to do things right at the first time where I would have otherwise lost so much time or even the right way. I also want to extend my gratitude to the rest of the Grupo de Ciencias Planetarias (GCP) team at the UPV-EHU, and in particular to Ricardo Hueso for his countless hours devoted to the development of the pipeline PLAYLIST as well as countless images processing, and José Felix Rojas for his support based on a deep expertise in all the technology relevant to PlanetCam. Making a PhD while having a different full time job is not an easy task, but within the GCP team, 'standing on the shoulders of giants', everything became much easier. In fact, I doubt I would have otherwise made the decision to go for a PhD in my circumstances. I thank Drs. Asuncion Illarramendi and Dr. Iñaki Bikandi from UPV/EHU for their continuous support during laboratory measurements and Javier Lopez from the Universidad Carlos III for his stellar spectrum synthetic models. I also want to remember our friend and outstanding astrophysicist Javier Gorosabel, who supported PlanetCam team and was also there at Calar Alto during our GRB afterglow detection in 2013. His decease is the only thing I would like to forget from all my PhD experience. Of course all this work would have been impossible without the observation 'missions' performed from 2012 to 2017 at Pic-du-Midi, Instituto de Astrofísica de Canarias and, in particular, Calar Alto observatories. Special thanks to the staff at Calar Alto for their support in so many long nights throughout these years, making easy to me even the remote connections and other information technology stuff. And, after all, the food up there was not so bad. My family also had to suffer my absence not only during my trips to the observatories but also for many hours devoted to this work when I was expected to be with them, so somehow this work is also theirs.

This paper provides a summary of the work done within Phase III of the Offshore Code Comparison, Collaboration, Continued, with Correlation and unCertainty project (OC6), under International Energy Agency Wind Task 30. This phase focused on validating the aerodynamic loading on a wind turbine rotor undergoing large motion caused by a floating support structure. Numerical models of the Danish Technical University 10-MW reference wind turbine were validated using measurement data from a 1:75 scale test performed during the UNsteady Aerodynamics for FLOating Wind (UNAFLOW) project and a follow-on experimental campaign, both performed at the Politecnico di Milano wind tunnel. Validation of the models was performed by comparing the loads for steady (fixed platform) and unsteady wind conditions (harmonic motion of the platform). For the unsteady wind conditions, the platform was forced to oscillate in the surge and pitch directions under several frequencies and amplitudes. These oscillations result in a wind variation that impacts the rotor loads (e.g., thrust and torque). For the conditions studied in these tests, the system mainly described a quasi-steady aerodynamic behavior. Only a small hysteresis in airfoil performance undergoing angle of attack variations in attached flow was observed. During the experiments, the rotor speed and blade pitch angle were held constant. However, in real wind turbine operating conditions, the surge and pitch variations would result in rotor speed variations and/or blade pitch actuations depending on the wind turbine controller region that the system is operating. Additional simulations with these control parameters were conducted to verify the fidelity between different models. Participant results showed in general a good agreement with the experimental measurements and the need to account for dynamic inflow when there are changes in the flow conditions due to the rotor speed variations or blade pitch actuations in response to surge and pitch motion. Numerical models not accounting for dynamic inflow effects predicted rotor loads that were 9 % lower in amplitude during rotor speed variations and 18 % higher in amplitude during blade pitch actuations.

This paper describes an approach and ICT tool developed for manufacturing process energy efficiency optimization, in particular focused on the heat treatment process of steel casting parts. Traditionally this manufacturing process is designed based on experts experience selecting a predefined temperature-time curve provided customer specifications for the resulting steel parts. However this curve can actually be optimised in terms of energy consumption while keeping required mechanical properties. This improved design is what the tool here described provides, using knowledge based approach for process design and multivariate optimisation and simulation techniques for process optimisation.

Esta nueva herramienta consta de dos modulos diferentes: modulo de reconocimiento de entornos interiores y modulo de comandos tactiles. El primero de ellos permite el reconocimiento de entornos interiores (oficinas, casas, etc.) mediante el tacto y con ayudas de audio, reconociendo las formas, tamano y textura de los objetos que los componen. El modulo de comandos tactiles permite el control de las aplicaciones mediante paneles de comandos/botones a los que el usuario puede acceder con el tacto, evitando de esta forma el procedimiento actual de raton-iconos que no es valido para las personas ciegas.

The work here described is related to the enhancement of existing manufacturing process design methodology and tools with a set of ICT components developed allowing process knowledge based design, simulation and optimisation in terms of energy efficiency. In particular the work described is focused on the heat treatment process of steel casting parts. This process design traditionally consists of a suitable predefined temperature-time curve selection based on personal experience and given customer requirements (material and mechanical properties), yet this curve can actually be optimised in terms of energy consumption and maintenance cost, while keeping required mechanical properties.
