An Efficient 2.5-D Finite-Element Approach Based on Transformation Optics for the Analysis of Elliptical Horns
No full textThis paper describes a new method to analyze elliptical horns. The method is based on a coordinate transformation, which maps the elliptical shape to a circular shape, allowing to use the 2.5-D body-of-revolution finite-element method formulation with a greatly improved efficiency over 3-D methods. Applications are shown to the analysis and design of shaped arbitrary axial ratio horns
Los estudios de Renzo de Felice y Emilio Gentile en la historiografía argentina : tres ejemplos
No full textRastreo de la huella que los estudios sobre el fascismo de los historiadores italianos Renzo de Felice (1929-1996) y Emilio Gentile (n. 1946) dejaron en la historiografía argentina. Para cumplir tal objetivo se recurre a las lecturas metodológicas y conceptuales que se verifican en tres intelectuales argentinos: los historiadores Fernando Devoto (n. 1947) y Federico Finchelstein (n. 1975) y el sociólogo Juan José Sebreli (n. 1930).The author traces back the studies on Fascism made by Italian historians Renzo de Felice (1929-1996) and Emilio Gentile (b. 1946) as part of Argentinian historiography. To achieve this objective, the author reviews their methodological and conceptual readings as noted by three Argentinian intellectuals: historians Fernando Devoto (b. 1947) and Federico Finchelstein (b. 1975), and sociologist Juan José Sebreli (b. 1930)
Spatial modulation for generalized MIMO: challenges, opportunities and implementation
No full textA key challenge of future mobile communication research is to strike an attractive compromise between wireless network's area spectral efficiency and energy efficiency. This necessitates a clean-slate approach to wireless system design, embracing the rich body of existing knowledge, especially on multiple-input-multiple-output (MIMO) technologies. This motivates the proposal of an emerging wireless communications concept conceived for single-radio-frequency (RF) large-scale MIMO communications, which is termed as SM. The concept of SM has established itself as a beneficial transmission paradigm, subsuming numerous members of the MIMO system family. The research of SM has reached sufficient maturity to motivate its comparison to state-of-the-art MIMO communications, as well as to inspire its application to other emerging wireless systems such as relay-aided, cooperative, small-cell, optical wireless, and power-efficient communications. Furthermore, it has received sufficient research attention to be implemented in testbeds, and it holds the promise of stimulating further vigorous interdisciplinary research in the years to come. This tutorial paper is intended to offer a comprehensive state-of-the-art survey on SM-MIMO research, to provide a critical appraisal of its potential advantages, and to promote the discussion of its beneficial application areas and their research challenges leading to the analysis of the technological issues associated with the implementation of SM-MIMO. The paper is concluded with the description of the world's first experimental activities in this vibrant research field
Laboratory measurements of super-resolving Toraldo pupils for radio astronomical applications
No full textThe concept of super-resolution refers to various methods for improving the angular resolution of an optical imaging system beyond the classical diffraction limit. Although several techniques to narrow the central lobe of the illumination Point Spread Function have been developed in optical microscopy, most of these methods cannot be implemented on astronomical telescopes. A possible exception is represented by the variable transmittance filters, also known as “Toraldo Pupils” (TPs) since they were introduced for the first time by G. Toraldo di Francia in 1952 (Toraldo di Francia, Il Nuovo Cimento (Suppl.) 9, 426, 1952). In the microwave range, the first successful laboratory test of TPs was performed in 2003 (Mugnai et al. Phys. Lett. A 311, 77–81, 2003). These first results suggested that TPs could represent a viable approach to achieve super-resolution in Radio Astronomy. We have therefore started a project devoted to a more exhaustive analysis of TPs, in order to assess their potential usefulness to achieve super-resolution on a radio telescope, as well as to determine their drawbacks. In the present work we report on the results of extensive microwave measurements, using TPs with different geometrical shapes, which confirm the correctness of the first experiments in 2003. We have also extended the original investigation to carry out full-wave electromagnetic numerical simulations and also to perform planar scanning of the near-field and transform the results into the far-field
Il governo del comico. Nuovi studi sulla narrativa italiana dal tre al cinquecento
No full textIl volume affronta la tradizione narrativa italiana da Boccaccio al secondo Cinquecento, mostrando come la lettura di tale repertorio in chiave esclusivamente comica sia errata, dato che sin dagli inizi, e tanto più nel pieno cinquecento, la novella si confronta con temi patetici e tragici, che raggiungono fama europea per le trasposizioni teatrali di molti raccontiThe volume deals with the italian short fiction tradition, from Boccaccio to Bandello, Giraldi, etc. The author aims to demonstrate that the traditional comic reading of such authors does not correspond with the broad readership of their books, which was strongly attracted by tragic tales, as can be seen with regard to the many theatrical versions of those stories
Second parent adoption e omogenitorialità
No full textThe Author analyses the decision from the European Court of Human Rights, Grand. Chamber, 19-2-2013, n. 19010/07 (X. vs. Austria), according to which the stable relationship of a cohabiting same-sex couple falls within the notion of "family life" pursuant to art. 8 of the ECHR read in conjunction with art. 14 ECHR, in the same way that a couple of different sexes would fall into the same situation. The Austrian law (art.182 ABGB) which allows, with the consent of the other natural parent of the minor, the adoption of the partner's child to unmarried couples, but not to same-sex couples, infringes the art. 14 ECHR in combination with art. 8 of the ECHR, because in this case the difference in treatment, being based only on sexual orientation, turns out to be unjustified. The Author criticizes some aspects of the reasoning of the sentence but investigates what could be the remedies offered by Italian law in similar cases

No full textIl saggio analizza un ciclo di affreschi del primo Cinquecento nel Palazzo Pretorio di Cittadella (Padova) mostrando come esso sia da ricondurre ai Trionfi di Petrarca anche con l'ausilio dei commenti coevi al Poema.The essay analyzes a cycle of frescoes in Cittadella (Padua), and deals with the problem of its sources. The author draws back the cycle to Petrarch's Trionfi
The Proposal for a European Foundation Statute and Its Influence on Italian Legislation
No full textThe essay examines the proposal for a European Foundation Statute presented by the European Commission in February 2012, which has been welcomed by many scholars and institutions as “a major step towards having a new legal tool that will make it easier for foundations to support public-benefit causes across the EU". The Author examines the possible effects of the Regulation (if entered into force) on the national laws with particular reference to Italian legislation
