Audiomobiles, Sculptures and Conundrums
No full textRoberto Gerhard was a pioneer of electronic music in England creating a number of substantial concert, theatre and radio works from as early as 1954. Gerhard’s electronic music is one of the richest repositories for understanding the development of the composer’s late compositional technique. Apart from the Symphony no.3, ‘Collages’, none of Gerhard’s electronic music is published. This paper will discuss aspects of Gerhard’s electronic music, focusing on Audiomobiles (1958-59) and Sculptures (1963)
Roberto Gerhard’s Sound Compositions: A Historical-Philological Perspective. Archive, Process, Intent and reenactment
No full textThis research advances the current state of knowledge in the field of early tape music both empirically and methodologically. The purpose of this study is to evaluate the impact that the electronic medium exerted in the musical thinking of Roberto Gerhard, one of the most outspoken, prolific and influential composers in the Spanish diaspora whose musical legacy, for the most part unknown, is a major landmark in the early history of electroacoustic music. Gerhard’s personal tape collection, one of the largest historical archives of its kind reported in the literature, is exceptional for both its antiquity (50+-year-old tapes) and its abundance of production materials. Through the digitisation and analysis of the composer’s tape collection this research argues that the empirical study of audio documents sets out a basis for a broader understanding of textual processes. More specifically, the research demonstrates that the reconstruction of works based on magnetic tape sketches is a powerful method to advance the understanding of early tape music. This research also examines Gerhard’s sound compositions in relation to the post-war context in which they were composed. Finally, this research presents performance documentation that proposes an approach to the electroacoustic music repertoire in which creativity is not at odds with rigor and critical discernment demonstrating that archival study can be closely aligned to the concept of re-enactment
Lost in Translation. About the Castilian Gloss on Giles of Rome’s De regimine principum
No full textThe paper shows how deep are the changes that Giles of Rome's de regimine principum undergoes in the so-called Castilian Gloss. the traditional attibution to the Franciscan friar Juan Garcia de Castrojeriz has been challenged. The paper claims, however, on internal evidence, that the author must have been a Franciscan friar. The book is edited by G. Briguglia and T. Ricklin
G.G. Rizzo, Il giardino privato di Roberto Burle Marx, Il Sítio. Sessant’anni dalla fondazione. Cent’anni dalla nascita di Roberto Burle Marx, Roma, Gangemi, 2009
Full text linkThe Sítio, a garden of 40 hectares, was founded by Roberto Burle Marx in 1949, at Guaratiba (Rio de Janeiro). It is also the center of the friendship between its author and Giulio G. Rizzo. In the book, Giulio Rizzo recalls its birth, the different phases of realization, the scientific and artistic components, the goals, the loving attention of its creator. He also condemns the absurdo actual management that makes it a intact ruin

Abstract: Study objective-The aim was to link individual demographic and medical records into sibships to obtain the sibling distribution of biopsies and cancers, and thereby calculate heritability and recurrence risks in families, thus aiding early diagnosis and prevention of cancers.
Design-The 157 823 individual records of the inhabitants of the town of Ferrara in Italy were automatically linked into 106 821 sibships. A 10% sample (10 842 sibships) was then extracted from the distribution of sibships and tabulated, for linkage to medical records.
Patients-The biopsy records at the Institute of Pathological Anatomy of the University of Ferrara were manually linked to cancer records and then to sibships. It was possible to construct the distribution of 2062 biopsies and of 829 cancers in sibships.
Results-From the distribution of biopsies and tumours in sibships, it was possible to estimate the incidence of tumours in the population (0.052) and in siblings of affected (0.083), and to apply to such distributions current methods for the estimate of heritability (h2 = 0.246) and of recurrence risks of tumours in sibships, age independent.
Conclusions-The study shows that the procedure resulting in the estimation of incidences and recurrence risks for tumours could be completely automated, and extended to whole populations and homogeneous subgroups in post industrial cultures
Lisbon 'Fado': the European Union under reform.
Full text linkTo address the uncertainties surrounding the
Treaty of Lisbon, this book examines several issues
from various angles. Regardless of the results
of the second referendum in Ireland and the
pending ratifications in Poland, the Czech
Republic and Germany, the European Union (EU)
will not be the same after the Lisbon Treaty.
If it comes into effect, Europeans will enter into
a new stage in the deepening of the integration
process; if it is rejected, the first decade
of the 21st Century will represent a period of
institutional stagnation in Europe’s integration.
Nonetheless, the chapters in this book share the
consensus that, despite its limitations,
the Lisbon Treaty will make the EU decision
making process more efficient, enhance regional
democracy and strengthenits international voice
Similar fillings and isolation of cusps of hyperbolic 3-manifolds
No full textIn this paper we deepen the analysis of certain classes M_{g,k} of hyperbolic 3-manifolds that were introduced in a previous work by B. Martelli, C. Petronio and the author. Each element of M_{g,k} is an oriented complete finite-volume hyperbolic 3-manifold with compact connected geodesic boundary of genus g and k cusps. We study small deformations of the complete hyperbolic structure of manifolds in M_{g,k} via a close analysis of their geodesic triangulations. We prove that several elements in M_{g,k} admit non-homeomorphic hyperbolic Dehn fillings sharing the same volume, homology, cusp volume, cusp shape, Heegaard genus, complex length of the shortest geodesic, length of the shortest return path, and Turaev-Viro invariants. Manifolds which share all these invariants are called geometrically similar, and were first studied by C. D. Hodgson, R. G. Meyerhoff and J. R. Weeks. The examples of geometrically similar manifolds they described are commensurable with each other. We show here that many elements in M_{g,k} admit non-commensurable geometrically similar Dehn fillings.
The notion of geometric isolation for cusps in a hyperbolic 3-manifold was introduced by W. D. Neumann and A. W. Reid and studied by D. Calegary, who provided explanations for all the previously known examples of isolation phenomena. We show here that the cusps of any manifold M_{g,k} are geometrically isolated from each other. Apparently, isolation of cusps in our examples arises for different reasons from those described by Calegari.
We also show that any element in M_{g,k} admits an infinite family of hyperbolic Dehn fillings inducing non-trivial deformations of the hyperbolic structure on the geodesic boundary
The deconstruction of politics in Roberto Esposito
No full textPartiendo de los seis textos centrales de la obra de Roberto Esposito, de los cuales se recogen sus principales elementos, este trabajo se centra en esclarecer la dirección que sigue el autor en su itinerario deconstructivo. Asimismo, también se enfoca en descifrar la conexión existente entre las principales categorías políticas que él trabaja –impolítico, communitas, inmunidad, biopolítica e impersonal– y en desenmascarar una lógica oculta, que se logra advertir en la profundidad de lo político. Esto permite dilucidar, que se ha acentuado una disposición hacia el cerramiento que afecta al léxico y las disposiciones políticas en general y la cual puede ser contrarrestada al abrir el horizonte de lo político a una perspectiva más amplia. (Texto tomado de la fuente).Taking in consideration the six central texts of Roberto Esposito's work, from which its main elements are collected, this work focuses on clarifying the direction that the author follows in his deconstructive itinerary. Likewise, this work also focuses on deciphering the connection between the main political categories that he works with –impolitical, communitas, immunity, biopolitics and impersonal– and on unmasking a hidden logic, which can be found in the depths of the political. This enables to elucidate that a disposition towards closure has been accentuated upon the political lexicon and dispositions, which can be counteracted by pushing the horizon of politics to a broader perspective.MaestríaMagíster en FilosofíaFilosofía PolíticaFilosofía Hermenéutic

Full text linkBehavioral modeling of GaN-based power amplifiers: impact of electrothermal feedback on the model accuracy and identification
Full text linkIn this article, we discuss the accuracy of behavioral models in simulating the intermodulation distortion (IMD) of microwave GaN-based high-power amplifiers in the presence of strong electrothermal (ET) feedback. Exploiting an accurate self-consistent ET model derived from measurements and thermal finite-element method simulations, we show that behavioral models are able to yield accurate results, provided that the model identification is carried out with signals with wide bandwidth and large dynamics
