This institution really taught me a lot of values, objectives and gave me the pillars to keep growing.Secondly, as this work was initially supported by National Founding from the FCT (Fun dação para a Ciência e a Tecnologia), I would like to thank Labcom for the opportunity to work in the Re/media.Lab project.
