Numerical evaluation of the electric field induced in a cubic phantom by different antennas at 2.45 GHz2011 International Conference on Electromagnetics in Advanced Applications
No full textPrevious studies evidenced that probes used to measure the electric field in the air are affected by an additional uncertainty, which increases as the field level grows, when measuring numerically modulated signals, such as those typical of the Wi-Fi standard at 2.45 GHz. To reliably evaluate the electromagnetic power absorbed by a body exposed to such signals, the behavior of the probes used for measuring the electric field inside biological media has to be characterized as well. To do this, one must have antennas able to induce high electric field values inside dissipative materials placed in the near field region. In this study numerical simulations have been carried out on two different antenna models (horn and loop) in order to evaluate the electric field distribution inside a cubic phantom. Results indicate that the printed loop antenna is more efficient than the horn one in inducing high values of electric field (tens of V/m) inside the phantom. Therefore, it can be efficiently used for the characterization of the electric field probes in the presence of digitally modulated signals at 2.45 GH
Perspettiva ridotta a perfezione: Glimpses of Daniele Barbaro’s Perspective Theory
No full textThis contribution is intended to identify some textual elements, apparently
secondary in Daniele Barbaro’s treatise on perspective, which either foreshadow
unprecedented developments in the discipline of representation or have
constituted complex critical nodes in the field of perspective. The first of these
is introduced in part V: anamorphosis (though never so called by the author, since
the term was not yet in use), suggesting a quick method to deform any flat image
by means of shadows. Finally, the author mentions two other ‘eccentric’ elements
of interest for the future developments of perspective that originated in Daniele
Barbaro’s text: an optical-projective device first introduced by Giovanni Battista
Vimercato, later developed by Jean François Niceron in his Thaumaturgus
opticus (1646), and the camera obscura
INTRUSION AND PRESENCE OF THE AUTHOR IN SAMUEL BECKETT’S “THE UNNAMABLE” AND B. S. JOHNSON’S “ALBERT ANGELO”
No full textThis article explores the intricate relationship between B.S. Johnson’s novel “Albert Angelo” and Beckett’s “The Unnamable”, both dealing with the issue of the possible presence of the author in his own text. The point of departure for such comparison is Johnson’s incorporation, as an epigraph, of a passage taken from Beckett’s novel. Such passage, intended rather literally by the British author, is employed as a justification not only for the central device at the heart of his novel, but also in support of a larger aesthetic project which will characterise a great part of his oeuvre – which famously stresses the importance of ‘truth’, as opposed to fabulation, and the necessity of the author’s direct presence in his texts. This contribution, in particular, tries to reconstruct the history of Johnson’s involvement with Beckett’s work, demonstrating how Johnson has in fact distorted the master’s message – perhaps intentionally – in order to produce a rather different model of literature, despite moving from very similar premises

No full textDaniele Barbaro and the Foundation of the Botanical Garden for the University of Padua
No full textWhen in the Renaissance the Venetian authorities decided to establish the Botanical Garden at the University of Padua in order to carry out experimental studies directly on plants, they entrusted Daniele Barbaro with the role of administrative supervisor. This essay, by comparing the Garden as built with documentary information and historical records, advances the hypothesis of a role not exclusively focused on economic aspects but also on considerations of design. Although information is scarce, the author reasonably speculates that Daniele Barbaro, probably assisted by other scholars and botanical experts, may have conceived the Hortus Sphaericus of Padua, an original design that was never completed
