De Angelis difusor de Vico: examen de un paradigma indiciario
No full textEl autor trata de determinar si la recepción de G. Vico en el contexto de la cultura rioplatense decimonónica se debió directamente a De Angelis o Michelet, aparentemente influido a su vez por De Angelis. Si la primera idea es plausible, dada la estancia del mismo italiano en la Argentina, entonces la conclusión parece clara: el verdadero papel de De Angelis en la difusión decimonónica de Vico no es un hecho, sino algo desconocido. Sin embargo, el hecho de que algo no se encuentre mostrado por la evidencia documental no impide su existencia ficcional.The author tries to determinate if the reception of G. Vico in the context of the River Plate Culture of the nineteenth century was due directly to De Angelis, or to Michelet, apparently influenced in turn by De Angelis. If the first idea is plausible, through the stay of the Italian himself in the Argentine, then the conclusion seems clear: the true rôle of De Angelis in the spread of Vico in the nineteenth century is an unknown, and not a fact. However, the fact that something is not shown by documentary evidence does not prevent it being fictionally suppoused
Archeologie postmoderne. Critici e narratori nella Bologna del Settantasette
No full textIl presente lavoro si propone di indagare uno spazio-tempo specifico e rappresentativo al tempo stesso, quello del Settantasette bolognese, che diviene il centro da cui poter osservare: i moventi e le pratiche del movimento di contestazione; le ricerche che in quegli anni portavano avanti i professori all’interno dell’università; la produzione narrativa di due generazioni, quella di Umberto Eco e Gianni Celati da una parte e quella di Enrico Palandri, Pier Vittorio Tondelli e Claudio Piersanti dall’altra. All’interno di questo panorama, l’archeologia rappresenta la metafora operativa scelta per tentare di ricostruire il catalogo delle idee e degli “artefatti” d’un periodo storico segnato dal capitalismo avanzato, una società del controllo e dello spettacolo e una logica culturale postmoderna.
È in risposta a questo nuovo assetto sociale che si possono spiegare le pratiche creative del movimento (del collettivo A/traverso in particolare) basate sul decentramento della contestazione nei campi del linguaggio e dei media. Dalle piazze ci sposteremo all’interno dell’università e al periodo che ricopre il decennio precedente il Settantasette, per approfondire due linee di ricerca significative: l’indagine archeologica – che si sviluppa intorno al progetto di una rivista, «Alì Babà», cui partecipano Celati, Guido Neri, Carlo Ginzburg, Enzo Melandri e, fuori dal contesto universitario, Italo Calvino – che vuole recuperare il “rimosso storico” e per cui ci sarà particolarmente utile il contributo di Ginzburg sul paradigma indiziario e le sue implicazioni epistemologiche; e la cultura popolare – a partire dall’analisi che ne fa Bachtin nel libro dedicato a Rabelais – che indaga (nelle diverse declinazioni disciplinari) i soggetti, le pratiche e i saperi che sono stati ridotti al silenzio dalla storia ufficiale. Approfondiremo poi l’opera saggistica di Eco (ricostruendone le diverse teorie dell’interpretazione, applicate al segno, ai testi e alla cultura di massa) e di Celati (in particolare le riflessioni sul novel e sul comico), ponendoli in dialogo negli spazi di ricerca convergenti. Tratteremo infine l’opera narrativa di Celati ed Eco – rappresentanti di due diverse posture all’interno del panorama postmoderno, che fa del “recupero” la sua cifra estetica – e dei “giovani scrittori” che di quel Settantasette erano stati protagonisti, concentrandoci unicamente sui testi pubblicati negli anni Settanta e Ottanta.This work aims to investigate a space-time that is specific and representative at the same time, that of Bologna in 1977, which becomes the centre from which to observe: the motives and practices of the protest movement; the research carried out in those years by professors within the university; the narrative production of two generations, that of Umberto Eco and Gianni Celati on the one hand and that of Enrico Palandri, Pier Vittorio Tondelli and Claudio Piersanti on the other. Within this panorama, archaeology represents the operational metaphor chosen to attempt to reconstruct the catalogue of ideas and “artefacts” of a historical period marked by advanced capitalism, a society of control and spectacle, and a postmodern cultural logic.
It is in response to this new social order that the creative practices of the movement (of the A/traverse collective in particular) based on the decentralisation of contestation in the fields of language and media can be explained. From the streets we will move to the university and to the period covering the decade prior to the 1970s, in order to investigate two significant lines of research: the archaeological investigation – which is developed around the project of a magazine, “Alì Babà”, in which Celati, Guido Neri, Carlo Ginzburg, Enzo Melandri and, outside the university context, Italo Calvino participate – which aims to recover the “historical removed” and for which Ginzburg's contribution on the circumstantial paradigm and its epistemological implications will be particularly useful; and popular culture – starting from Bachtin's analysis of it in the book dedicated to Rabelais – which investigates (in the various disciplinary declinations) the subjects, practices and knowledge that have been reduced to silence by official history. We will then delve into the non-fiction work of Eco (reconstructing his various theories of interpretation, applied to the sign, texts and mass culture) and Celati (in particular his reflections on the novel and the comic), placing them in dialogue in the converging spaces of research. Lastly, we will deal with the narrative work of Celati and Eco – representatives of two different positions in the post-modern panorama, which makes “recuperation” its aesthetic mark – and of the “young writers” who were the protagonists of 1977, concentrating only on the texts published in the 1970s and 1980s.Ce travail se propose d’enquêter sur un espace-temps à la fois spécifique et représentatif, celui de Bologne en 1977, qui devient le centre d’où l’on peut observer: les motifs et les pratiques du mouvement contestataire; les recherches menées dans ces années-là par les professeurs de l’université; la production narrative de deux générations, celle d’Umberto Eco et de Gianni Celati d’un côté et celle d’Enrico Palandri, de Pier Vittorio Tondelli et de Claudio Piersanti dans l’autre. Dans ce panorama, l’archéologie représente la métaphore opérationnelle choisie pour tenter de reconstruire le catalogage des idées et des « artefacts » d’une période historique marquée par le capitalisme avancé, une société de contrôle et du spectacle, et une logique culturelle postmoderne.
C’est en réponse à ce nouvel ordre social que s’expliquent les pratiques créatives du mouvement (du collectif A/traverso en particulier) fondées sur la décentralisation de la contestation dans les domaines du langage et des médias. Ensuite, nous nous déplacerons vers l’université et vers la période couvrant la décennie précédant le 1977, afin d’étudier deux lignes de recherche importantes: l’enquête archéologique – qui se développe autour du projet d’une revue, «Alì Babà», à laquelle participent Celati, Guido Neri, Carlo Ginzburg, Enzo Melandri et, hors du contexte universitaire, Italo Calvino – qui vise à récupérer le « refoulé historique » et pour laquelle la contribution de Ginzburg sur le paradigme indiciaire et ses implications épistémologiques sera particulièrement utile; et la culture populaire – à partir de l’analyse qu’en fait Bachtin dans son livre sur Rabelais – qui enquête (dans ses diverses déclinaisons disciplinaires) sur les sujets, les pratiques et les connaissances qui ont été réduits au silence par l’histoire officielle. Nous nous plongerons ensuite dans l’œuvre non romanesque d’Eco (en reconstruisant ses différentes théories de l’interprétation, appliquées au signe, aux textes et à la culture de masse) et de Celati (notamment ses réflexions sur le novel et le comique), en les faisant dialoguer dans les espaces convergents de la recherche. Enfin, nous aborderons l’œuvre narrative de Celati et d’Eco – représentants de deux postures différentes dans le panorama postmoderne, qui fait de la « récupération » sa marque esthétique – et des « jeunes écrivains » protagonistes du 1977, en nous concentrant uniquement sur les textes publiés dans les années 70 et 80
Validation and comparison of circular coils’ inductive coupling models
No full textIn this paper, modeling of inductive coupling between circular coils is analyzed. We present a system for measuring the mutual inductance and the magnetic flux between resonant coils. We investigate the accuracy and precision against data obtained through the FastHenry2 simulation software and through experiments, when these are available (Pasku et al., 2017). The theoretical background is discussed, theoretical models are presented, and their properties are compared to those of other published models. A practical implementation is illustrated and employed to validate the considered numerical models. Obtained results demonstrate that the proposed modeling and experimental setup provide high-accuracy measurements of the induced voltage. Field measurements validate the considered numerical models with a discrepancy of less than 10% with respect to measurement results

Parallel PN code acquisition for wireless positioning in CDMA handsets
No full textThis paper proposes a simplified acquisition system for finding and identifying Base Stations (BSs) in visibility in the framework of a CDMA wireless positioning system, based on IS-95 cellular standard. The problem of having more than one BS in the same PN code acquisition system makes it necessary to discriminate between correct detection and false alarm events. Since IS-95 uses the same PN sequence for all BSs, but with different code offsets, it is possible to use a cross-correlation technique to estimate both code and frequency offsets of several BSs at once. Time-Difference-Of-Arrival (TDOA) technique is used by the Mobile Station (MS) to geolocate itself. The positioning estimate is found to be stable in time and with a precision compatible with that required by emergency services, such as Enhanced 911 (E911)
Mean spherical model for strongly coupled dusty plasmas
No full textA solution of the mean spherical model is presented for particles interacting with a pair potential which is repulsive at short-range and attractive at long-range. The solution can be used for the description of the structure of strongly-coupled dusty plasmas, represented as one component systems of dust particles with an interaction potential determined by the plasma dynamics; a screened Coulomb repulsive interaction at short distances and a long-range attraction due to a screened “shadow effect” on the plasma fluxes to the dust particles. A comparison with recent experimental results shows a better agreement when the attractive potential is present
