Polar POLICRYPS Diffractive Structures Generate Cylindrical Vector Beams
Domenico Alj,Sathyanarayana Paladugu,Giovanni Volpe,Roberto Caputo,Cesare Umeton
Physics , 2015,
Abstract: Local shaping of the polarization state of a light beam is appealing for a number of applications. This can be achieved by employing devices containing birefringent materials. In this article, we present one such device that permits one to convert a uniformly circularly polarized beam into a cylindrical vector beam (CVB). This device has been fabricated by exploiting the POLICRYPS photocuring technique. It is a liquid-crystal-based optical diffraction grating featuring polar symmetry of the director alignment. We have characterized the resulting CVB profile and polarization for the cases of left and right circularly polarized incoming beams.
An Overview of Westinghouse Realistic Large Break LOCA Evaluation Model
Cesare Frepoli
Science and Technology of Nuclear Installations , 2008, DOI: 10.1155/2008/498737
Abstract: Since the 1988 amendment of the 10 CFR 50.46 rule in 1988, Westinghouse has been developing and applying realistic or best-estimate methods to perform LOCA safety analyses. A realistic analysis requires the execution of various realistic LOCA transient simulations where the effect of both model and input uncertainties are ranged and propagated throughout the transients. The outcome is typically a range of results with associated probabilities. The thermal/hydraulic code is the engine of the methodology but a procedure is developed to assess the code and determine its biases and uncertainties. In addition, inputs to the simulation are also affected by uncertainty and these uncertainties are incorporated into the process. Several approaches have been proposed and applied in the industry in the framework of best-estimate methods. Most of the implementations, including Westinghouse, follow the Code Scaling, Applicability and Uncertainty (CSAU) methodology. Westinghouse methodology is based on the use of the WCOBRA/TRAC thermal-hydraulic code. The paper starts with an overview of the regulations and its interpretation in the context of realistic analysis. The CSAU roadmap is reviewed in the context of its implementation in the Westinghouse evaluation model. An overview of the code (WCOBRA/TRAC) and methodology is provided. Finally, the recent evolution to nonparametric statistics in the current edition of the W methodology is discussed. Sample results of a typical large break LOCA analysis for a PWR are provided.
Per una pedagogia dello sport: riflessioni dall'Italia
Educación y Educadores , 2009,
Abstract: the current image of sports is fundamentally negative. however, the connection between education and sports should be reinforced, while recognizing it as being hypothetic rather than automatic, and subject to the necessary educational controls. each sport has its own perfection and can contribute to the moral, social, intellectual and ethical development of human beings. the analysis considers some of the areas where that development occurs and underscores a few of the more relevant problems (early competition, education for life, impact of the mass media, etc.) to be addressed for the sake of establishing progress later on.
Identity, Flexibility and Sustainability for the new Social Housing
Cesare Sposito
Techne : Journal of Technology for Architecture and Environment , 2012,
Abstract: Pubblica (lit. Public Residential Construction), undergone over the last sixty years in Italy, have brought about new lines of thought with regard to places to live. The high cost of renewal and re-functionalization of the E.R.P. areas, the absence of services, which have transformed them into dormitory suburbs, have led us to rethink new urban environments as places possessing a sense of identity, in which to provide communal services and spaces for neighborly relations. Moreover, the social, economic and political dynamics of the last few years have modified not only life styles, but also the typology of householder, ever more sensitive to the quality of product and environmental issues. This contribution discusses several principles as a point of departure for a new Social Housing.
Appunti per una lettura di Cléopatre (1829) di Hector Berlioz Notes for a reading of Cléopatre (1829) by Hector Berlioz
Cesare Fertonani
Lanx , 2011, DOI: 10.6092/2035-4797/1264
Abstract: Hector Berlioz compone la sua Cléopatre su un tema indicato per il Prix de Rome del 1829, che era certo di vincere. Proprio per questo motivo, musicando un breve testo di poca ispirazione di Vieillard, ma avendo in mente il monologo della Giulietta shakespeariana sulla sepoltura, Berlioz si sente libero di condurre la sua sperimentazione verso novità audaci in linea con quella poetica del teatro ideale e della memoria che svilupperà in seguito, realizzando l’opera più significativa della sua giovinezza, ma scontentando la giuria del premio. Hector Berlioz composed Cléopatre to compete for 1829 Prix de Rome. He was so sure to win the prize that – setting a short Vieillard’s text to music having in mind Shakespeare’s Juliet monologue about sepulture – he allowed himself to indulge in formal experimentations perfectly coherent with his research about an ideal theater and the theme of memory, both developed in his later years. This is the reason why Cléopatre displeased the jury but remains young Berlioz’s best achievement.
Ensayo analítico sobre el contrabando

De la tortura (1764).
Cesare Beccaria
Revista de la Asociación Espa?ola de Neuropsiquiatría , 1999,
Abstract: He aquí uno de los capítulos más certeros, más famosos y más eficaces del libro de Beccaria.Poco importa el lector no erudito que parte de los datos y argumentos encerrados en estos párrafos procedan (como afirman algunos críticos italianos actuales) de Pietro Verri, el mentor de Beccaria. En todo caso, quien los divulgó, quien construyó con ellos un capítulo coherente, apasionado, sintético y noblemente efectista, fue Beccaria. Otro acierto suyo consistió en no desgajar la censura contra la tortura de idéntico juicio condenatorio contra todo el sistema procesal penal. Era imposible sustituir la tortura por otras pruebas más objetivas, sin sustituir al mismo tiempo todo el proceso penal ‘ofensivo’ –como lo llama Beccaria en el cap. XL– por otro de carácter meramente ‘informativo’. Beccaria fue, quizá, el primero en comprenderlo así y en así escribirlo. En este punto su vehemente y razonada condena supera en mucho al comentario que sobre la tortura escribió Montesquieu, de quien tantas otras ideas tomó Beccaria . Esta es la nota a De los delitos y las penas que pone su traductor Francisco Tomás y Valiente, gran ilustrado de nuestro presente inmediato, autor de La tortura en Espa a, otro libro indispensable.
