Multifractal behavior of polynomial Fourier series

We prove non-trivial upper and lower bounds for the "Spectrum of Singularities" of Fourier Series with polynomial frequencies. The Spectrum of Singularities of a function f gives the Hausdorff dimension of the set of points with a given H\"older exponent for f.Comment: 36 pages, 2 figures. Submitted for publicatio

From explicit prohibition to ambiguity in prohibiting

El trabajo fue presentado en la sección monográfica sobre lenguaje tabú en el mencionado congreso.This contribution will deal with two topics closely related and intermingled. I firstly will try to show how one of the salient features of euphemisms is their ambiguity and/or vagueness (Grondelaers and Geeraerts, 1998) to the extent that even sentences in which lexicalised euphemisms are used can become dysphemistic if they are not ambiguous. This means that ambiguous and/or vague sentences play a fundamental, cognitive role (Tuggy, 2006). This is the case of a well-known excerpt from Somerset Maugham in which, in spite of the fact that all the nouns used are euphemisms, the excerpt itself can be considered dysphemistic. Conversely, I will show two instances from two songs in which female pudenda are euphemistically and ambiguously alluded to. Secondly, I will try to apply my previous reflections to politically correct language. In order to do so I will take as a starting point the fact that political correctness spread across the western countries in the same decade (1960-1970) in which the motto “Il est interdit d’interdire” got also trendy (Hughes, 2006 and 2010). As a result of the fact that the noun ‘prohibition’ (and its cognates, derivatives and synonyms) became “prohibited” as a politically incorrect word, prohibition itself has to be phrased in ambiguous sentences. For instance, instead of the (currently) politically incorrect notice “No Smoking” or “Smoking is prohibited”, we frequently find the politically correct one “Thank you for not smoking”, where the sentence meaning is pretty different from what the author of the notice tries to mean; since the sentence meaning is that someone thanks you for not smoking, while what the author of the notice intends to mean that smoking is prohibited.Universidad de Málaga.

Solar UAV for long endurance flights

The project have been done during the four months stay in Lithuania by Marc Olmo and LLibert Chamizo. The aim of the project was to obtain an Unmanned Aerial Vehicle powered by solar energy that was able to flight for as long as possible it within the limitations which are the budget, the time and the technological limitations. During the limited time, the team have been working in all the necessary phases to build a real scale and fully functional Solar UAV. This phases were the following; Theoretical Calculations, Design, Simulation, Building, Tests of the Airframe, Solar Energy Circuit Design and Building 2nd phase tests and Conclusion Obtaining. Through all the process several technical and engineering decisions have been made leading the team to obtain a fully functional 4,4m wingspan fixed wing UAV with a TOW of 5,5 Kg which is perfectly pilotable The final achievements have been a UAV capable of long endurance flight within daytime. The model achieved was able to maintain level, climb and turn perfectly using just the power gathered by the solar cells in its wing. During the development of the project the possibility of the multiday flight have been discussed leading to the conclusion that it's viable but not within the frame of this project. There have been done several tests under actual mission parameters loading the plane with the weight it would be carried during the missions that are most likely solar uav related such as mapping or surveillance. The final result have been correct and lead to an optimistic opinion about the whole Solar UAV paradigm and about the prototype modification and improvement in the near future to achieve even better results (which have been overviewed and planned in the actual report). A fatal error drove the airplane to a nosedive fall with disastrous consequences, the whole project feels and success though it's undoubtable
