Language and Collective Identity in Buñuel. Propaganda in the Film «España 1936»

En la memoria colectiva de los europeos, la Guerra Civil española ocupa un lugar destacado. El lenguaje cinematográfico y la representación fílmica de esa contienda forman un ámbito relevante en el que estudiar algunos rasgos de la matriz cultural europea. El presente trabajo selecciona parte de la producción fílmica de propaganda del gobierno republicano, en concreto los filmes de montaje supervisados por Luis Buñuel. Al inicio de la contienda el cineasta aragonés vuelve a París siguiendo las indicaciones del Ministerio español de Asuntos Exteriores para colaborar, en la embajada española en la capital francesa, en diversas labores de contraespionaje y propaganda. Entre ellas y principalmente, Buñuel se ocupa de reunir, organizar y montar diverso material fílmico prorrepublicano. A diferencia de otras producciones proyectadas en España, los filmes parisinos de propaganda republicana se caracterizaron, en términos generales, por estar dirigidas a públicos de distintos países europeos con el objetivo de romper la doctrina de no intervención en el conflicto y se inscriben dentro de las teorías y concepción de Buñuel sobre el documentalismo filmado, donde primaba lo reflexivo y los recursos psicológicos que motivaran a la acción o a la toma de conciencia individual. El presente texto se ocupa, en ese contexto, de la descripción y el análisis del lenguaje y las prácticas fílmicas en esos años. De todas ellas, el filme «España, 1936» (1937), es a la vez un ejemplo emblemático y singular

Quantum Physics and Signal Processing in Rigged Hilbert Spaces by means of Special Functions, Lie Algebras and Fourier and Fourier-like Transforms

Quantum Mechanics and Signal Processing in the line R, are strictly related to Fourier Transform and Weyl-Heisenberg algebra. We discuss here the addition of a new discrete variable that measures the degree of the Hermite functions and allows to obtain the projective algebra io(2). A Rigged Hilbert space is found and a new discrete basis in R obtained. The operators {O[R]} defined on R are shown to belong to the Universal Enveloping Algebra UEA[io(2)] allowing, in this way, their algebraic discussion. Introducing in the half-line a Fourier-like Transform, the procedure is extended to R^+ and can be easily generalized to R^n and to spherical reference systems.Comment: 12 pages, Contribution to the 30th International Colloquium on Group Theoretical Methods in Physics, July 14-18, 2014, Gent (Belgium

Polar coding for confidential broadcasting

A polar coding scheme is proposed for the Wiretap Broadcast Channel with two legitimate receivers and one eavesdropper. We consider a model in which the transmitter wishes to send the same private (non-confidential) message and the same confidential message reliably to two different legitimate receivers, and the confidential message must also be (strongly) secured from the eavesdropper. The coding scheme aims to use the optimal rate of randomness and does not make any assumption regarding the symmetry or degradedness of the channel. This paper extends previous work on polar codes for the wiretap channel by proposing a new chaining construction that allows to reliably and securely send the same confidential message to two different receivers. This construction introduces new dependencies between the random variables involved in the coding scheme that need to be considered in the secrecy analysis.Peer ReviewedPostprint (published version
