A beamforming approach to the self-calibration of phased arrays

In this paper, we propose a beamforming method for the calibration of the direction-independent gain of the analog chains of aperture arrays. The gain estimates are obtained by cross-correlating the output voltage of each antenna with a voltage beamformed using the other antennas of the array. When the beamforming weights are equal to the average cross-correlated power, a relation is drawn with the StEFCal algorithm. An example illustrates this approach for few point sources and a 256-element array

Estructura del alma en el fedro

El presente artículo trata de recoger la caracterización del alma humana que Platón ofreceen el diálogo Fedro. Para ello, hemos centrado nuestra atención en el símil del carro aladode la palinodia, atendiendo a su contexto dramático y extrayendo los aspectos más relevantes.El resultado no es desdeñable: el Académico, conocido por su ascetismo y su esfuerzoconstante por privilegiar la razón y el intelecto, ofrece una novedosa imagen delalma humana, fijando el éros como su núcleo y principio vital. En esencia, el alma humanaes deseo, y, análogamente, su parte más excelsa, a saber, el intelecto, es deseo de conocimiento.This paper aims to summarize the characterization of the human soul given by Plato’sPhaedrus. To this end we have focused on the allegory of the winged chariot depicted inthe palinode, considering its dramatic context and analyzing it in detail. The result isdefinitely significant: the founder of the Academy, well-known for his asceticism and hiscontinuous effort to favor reason and the intellect, offers an original image of the humansoul, which sets éros as its core and as its vital principle. Substantially, the human soul isdesire and, similarly, its most preeminent part, i.e. the intellect, is desire for knowledge

The Prayer to Pan of Plato’s Phaedrus (279b8–c3): An Exhortation to Exercise the Philosophical Virtue

The current article offers a new reading of Socrates’ prayer to Pan in Plato’s Phaedrus. By means of a comprehensive approach, the paper shows that the prayer not only gathers together the most relevant topics dealt with during the conversation, but it also exhorts us to engage in the way of life depicted by Socrates’ character, namely that of philosophy, which can be clearly distinguished from that of traditional rhetoric. To this extent, eros and logos, two elements closely related to Pan, show themselves to be of primary relevance. Besides these issues, we discuss the puzzling nature of the prayer, defending the idea that it was authored with the same writing method as the full dialogue. Socrates’ psychagogic attempt with Phaedrus is analogous to Plato’s didactic effort to engage the reader in philosophy: instead of supplying a straight message which must be learnt by heart by Phaedrus or the reader, both Socrates and Plato offer friendly logoi intended to promote active research in the receivers.Fundació Universitària Agustí Pedro i Pon

Epistemological struggle, power struggle: from tetelesménon to dókos

The significant role of the translator: an illustration of the analytical and documentary work to be developed in the translation of a specialized medical text

The aim of this undergraduate dissertation is to claim the significance of the translator’s role, as well as to exemplify the analytical and documentary work to be developed in specialized medical translation. In order to achieve this purpose, the translator’s dilemma has been briefly discussed, noting the underestimation and criticism typically associated with this profession. Furthermore, medical language has been covered in depth to illustrate potential translation problems. Before translating, an analysis of the main features of the ST has determined the communicative context at issue. The methodology followed for the subsequent translation has been based on documentation, particularly on the consultation of Spanish parallel texts. Finally, some examples regarding translation procedures and medical language have been spotted and commented after the elaboration of the TT. These results have provided a work model for medical translators and have confirmed the complexity of specialized professional translation.El objetivo de este proyecto es defender la importancia del traductor y ejemplificar el trabajo analítico y documental a desarrollar en la traducción médica especializada. Para conseguir dicho propósito, se ha tratado brevemente el dilema del traductor, haciendo hincapié en la infravaloración y la crítica que suelen asociarse a esta profesión. Asimismo, se ha hablado con detalle del lenguaje médico para poner de manifiesto posibles problemas de traducción. Antes de traducir, un análisis de las principales características del TO ha determinado el contexto comunicativo en cuestión. La metodología utilizada durante la traducción se ha basado en documentación, concretamente en la consulta de textos paralelos españoles. Tras la elaboración del TM, se han comentado algunos ejemplos relacionados con los procedimientos de traducción y el lenguaje médico. Estos resultados han proporcionado un modelo de trabajo para traductores médicos y han constatado la complejidad de la traducción profesional especializada.Departamento de Filología InglesaGrado en Estudios Inglese

Antilogy, dialectic and dialectic’s objects in Plato’s Phaedrus

Plato’s Phaedrus is a dialogue in which rhetoric is not only discussed, but also displayed. The first half of the plot depicts a rhetorical contest in which Socrates himself offers two opposite speeches on love, a kind of dissoi logoi. The current paper tries to explain that the second half of the dialogue offers the necessary keys to understand that for Plato true rhetoric is nothing but dialectic and that beyond the apparent antilogic exercise carried out by Socrates there can be found philosopher’s dialectical practice itself. Last but not least, the article defends that dialectic does not necessarily deal with Forms

A complementary observation to determine Phaedrus’ age in Plato’s Phaedrus

This paper deals with the problem of determining Phaedrus’ age in the eponymous dialogue. The vocatives ὦ νεανία and ὦ παῖ, in Pl. Phdr. 257c8 and 267c6, could suggest that Plato depicts him as a teenager. However, most scholars believe that Phaedrus is an adult and that the vocatives point at his passive and childish character. I will first summarize the evidence given for supporting the latter thesis. Then, I offer complementary evidence, showing that those vocatives mockingly compare his passiveness with that of a young beloved in a homoerotic context

Fight for Nothing: Fight Club and Nihilism in Capitalist Society

This paper analyses the movie Fight Club (1999) from the philosophical point of view. We reflect on the split personality of the protagonist, showing how the former represents the subject of the modern society, who, unable to find completion in ceaseless consumerism, embarks upon a personal journey towards the annihilation of every value of his world. This process of annihilation, which at first takes the form of a closed group of people, evolves into an expansive way of annihilation. The latter symbolizes modern society’s evolved subject’s will to destroy the foundations of capitalist society
