Signal Processing Techniques for Chipless UWB RFID Thermal Threshold Detector Detection.

This letter presents signal processing techniques to detect a passive thermal threshold detector based on a chipless time-domain ultrawideband (UWB) radio frequency identification (RFID) tag. The tag is composed by a UWB antenna connected to a transmission line, in turn loaded with a biomorphic thermal switch. The working principle consists of detecting the impedance change of the thermal switch. This change occurs when the temperature exceeds a threshold. A UWB radar is used as the reader. The difference between the actual time sample and a reference signal obtained from the averaging of previous samples is used to determine the switch transition and to mitigate the interferences derived from clutter reflections. A gain compensation function is applied to equalize the attenuation due to propagation loss. An improved method based on the continuous wavelet transform with Morlet wavelet is used to overcome detection problems associated to a low signal-to-noise ratio at the receiver. The average delay profile is used to detect the tag delay. Experimental measurements up to 5 m are obtained.

Los orígenes de las reivindicaciones autonomistas catalanas y sardas a través de la prensa periódica del siglo XIX (1840-1890)

The purpose of the thesis for obtaining this PhD diploma is a comparative research between the origin of the Catalonian national movement and the Sardinian national one through the analysis of the 19th century periodicals as well as through a bibliography obtained by extracting them from consulted newspapers and magazines. Not only are both realities compared because of the Aragonese-Catalan influence over the Sardinian culture during its conquer but also because both movements had their origin during the 1840s and developed concurrently along that century presenting some differences, though. The political and cultural scene in Sardinia in those years was characterized by the spread of a discomfort feeling among the population after the acceptance of the “ Fusione perfetta” in 1848 and the following rollout of the “Statuto Albertino” in the island, representing this last regulation an attempt to unify the different Italian provinces in an administrative and legislative way, together with the previous “Feliciano” code from 1827. Therefore, this is how it began to be defined the set of political, economic, and cultural theme that forms the central point of the “questione sarda” (this term and its whole connotation were used for the first time in 1867 in an article published in the Cagliaritano weekly-publication La Cronaca). The singularity of this Sardinian nationalistic movement is related to the origin of the first regional demands expressed during those same years in some European regions and, more specifically, in Catalonia. Actually in this region, in those same years, we find the origin of a cultural movement called RenaixenÇa whose initial claim was the linguistic and cultural Catalonian renaissance and which adopted a more political meaning along the 19th century...

Avel·lí Artís i Balaguer (1881-1954), comediógrafo e impresor-editor. Entre la plenitud del cambio de siglos y el exilio

This thesis has its origin in a previous work: “The Catalan theatrical life in the magazine ‘El Teatre Català’ (1912-1917)” (DEA, UCM, 2004-2005), focused on the history, description and the indexes of that magazine. Among the historical and literary references ordered there, we chose a figure that would make a monographic work resulting in the present Doctoral Thesis. The choice fell on Avel·lí Artís i Balaguer (1881-1954), whose personality and literary corpus, allow additional possibilities for research. The cultural and literary reach of his life and his work covers a whole historical cycle in Catalan culture and literature, which moves from its contemporary consolidation towards the drama of its temporal dislocation, between the Spanish Civil War and the exile experience. This e historical itinerary is represented by Avel·lí Artís i Balaguer, being a playwright and a publisher. He’s been considered a comedy playwright since his editions bear titles such as “comedy”, “pas comedy”, “sainet” “quadro”, “farce” or “dialogue”, at most we find the word “Drama” once and “tragicomedy” twice, and we can find all this, in a series of texts for the representation ranging from 1909 to 1938. Secondly, as a professional fully involved in printing and publishing, thereby covering since its first steps as a compositor in the late nineties of the 19th century until his activity as a crucial character for magazines and other publishing projects, from the first decade of the 20th century until the last year of his Mexican exile...

I Jornadas sobre Arte, Ecología y Uso Público de Espacios Naturales Protegidos

Publicación de las Jornadas que celebró el mes de marzo de 2016, en el Parque Nacional Las Tablas de Daimiel, la asociación Cultura de Ribera con el objetivo de hacer de la cultura y el arte elementos para la conservación de nuestros Espacios Naturales Protegidos. Además de dar unas nociones sobre el paisaje y el territorio de La Mancha Húmeda, en la obra, se traza un panorama histórico sobre Las Tablas y su importancia como el primer Parque Nacional que fue declarado, en gran medida, gracias a la presión ciudadana y del, por entonces, incipiente movimiento ecologista. También se puede encontrar una visión ética de la conservación medioambiental, los antecedentes históricos y experiencias actuales del arte como vector para la conservación de los Espacios Naturales Protegidos y una reflexión sobre el papel del arte y las humanidades en el contexto de la crisis ecológica global. La obra se cierra con un artículo sobre la figura de Ignacio Meco, artista que en su obra aunaba arte y conservación del medio y que tuvo su casa taller en la Zona de Protección de Las Tablas.
