La negatività eversiva del canto leopardiano, intervista a Claudio Longhi
No full textContributo teso a portare in luce in forma dialogica le principali direttrici interpretative sottese all’allestimento di “Leopardi”, cabaret filosofico diretto da chi scrive per il Teatro Stabile di Torino sulla base di un montaggio di testi leopardiani curato sempre da chi scrive e debuttato il 9 novembre del 2005 presso il Teatro Vittoria di Torino. Il breve testo chiarisce come al fondo dello spettacolo citato stia una ricognizione sistematica delle diverse declinazioni di quella sorta di filosofia del riso che Leopardi inscrive allegoricamente tra le pieghe della sua opera. Tentando di oggettivare il sinuoso ed ambiguo dispiegarsi del discorso leopardiano tra monologo soggettivo e dialogo, il copione, che assembla frammenti dei “Canti” e delle “Operette Morali” sullo scheletro portante del “Discorso sullo stato presente dei costumi degli italiani”, è letto, nell’intervista, come una sorta di mappa del pensiero dell’autore. La radicale negazione dell’antropocentrismo che innerva tanta parte della prosa e dei versi leopardiani sempre fluttuanti sull’interminata vastità dell’infinito cosmico, la marginalità dello scrittore – che sa scrutare le «magnifiche sorti e progressive» del suo tempo dall’eremo di Recanati e che proprio del suo vivere ai margini sa nutrire, però, la spietata profondità del suo sguardo –, così come l’annichilente ironia del poeta, sono assunti nello scritto come prove della sconvolgente e inattualissima attualità di Leopardi, proposto nello spettacolo quale lancinante profeta della nostra contemporaneità. Il contributo si sofferma infine sull’analisi della complessa relazione esistente tra musica e poesia e sul tentativo di creare un ponte tra la cultura tedesca e Leopardi, per il tramite di reagenti estetici come le composizioni di Schubert e Schumann utilizzate quali proiezioni e matrici musicali della scrittura del poeta marchigiano
Fusion of Radio and Video Localization for People Tracking
No full textIn this paper we introduce a hybrid people tracking system based on the combined use of RFID UWB technology and computer vision techniques. The proposed system takes advantage of the different characteristics of the vision and wireless subsystems to achieve better accuracy and reliability for people tracking. Moreover data gained from the subsystems can be used for a more complex context capture system and can be seen as an enabler of a number of application from video-surveillance to Ambient Intelligence scenarios. Different scenarios have been tested to assess the feasibility and performance of the system. Experimental results demonstrate advantages in people tracking tasks encouraging further researches
THE DEVELOPMENT OF THE KAPTON SIGNAL ROUTER FOR THE SILICON MICROSTRIPS DETECTOR OF L3
No full textA high precision kapton cable to route the signals of the double sided silicon microstrips detector (SMD) to the front-end electronics has been developed. The mechanical and electrical properties of this cable are stable against variations in humidity and temperature and maintain the cross talk between adjacent lines below 3%. Electron beam photolithography and chemical etching have been used to produce a very dense signal router: 744 L shaped strips on a surface of similar or equal to 140 mn X 40 mm, corresponding to a strip pitch of less then 50 mu m. The R&D work to find the correct electroplating parameters for both input and output bonding pads, to allow for automated wire bonding, as well as the results obtained during the SMD mass production are described
Preliminary results of floristic and vegetational surveys in three coastal humid areas in Puglia region (southern Italy).
No full textThis paper presents the preliminary results of an INTERREG project (III A Italy-Greece 2000-2006) concerning the improvement and management of common ecosystems. This project includes several humid areas located within the northwestern regions of Greece and the Italian region of Apulia. Owing to their similar paleogeographical and paleoclimatical accidents these areas exhibits several floristic and coenological peculiarities which lead to their inclusion in the Adriatic Province of the eastern Mediterranean biogeographical sub-region. The project involves making a GIS which permits the acquisition, processing, analysis, storage and feedback in graphic and alphanumeric form of the ecological data collected in three of the most significant coastal humid protected areas of the Apulia region, namely “Torre Guaceto”, “Le Cesine”, and “Saline di Punta della Contessa”. The importance of these humid areas can be inferred simply by observing the high number of Dir. 92/43/EEC habitats they contain. It is well-known that there are many negative factors which are currently threatening the Mediterranean retro-dunal ecosystems such as air and water pollution, urbanization, the impact of mass tourism, coastal erosion, lowering of the ground water table (etc.). These areas therefore urgently require a system of constant monitoring and, where necessary, actions to restore vegetation. All this demands a background of landscape knowledge concerning the small-scale vegetation pattern (actual heterogeneity) and the potential vegetation types (potential heterogeneity) as well. The three Apulian areas in the present study can easily be distinguished from each other from a floristic and coenological point of view. In addition to the slight (but probably crucial) differences in their physical environments, the existing diversity in the vegetation is more closely related to the minor and "unofficial" biogeographical boundaries prevailing in the part of the Apulian region and to the variation of the ecological optimum of several diagnostic species (Quercus ilex, Quercus calliprinos, Erica forskalii, Cladium mariscus, Plantago albicans, Limonium apulum....) than to the effective interruption of their distribution areas

Measurement of D-star Production In Jets From Pbarp Collisions At Square-root-s = 1.8 Tev
No full textThe production rate of charged D* mesons in jets has been measured in 1.8-TeV p»p collisions at the Fermilab Tevatron with the Collider Detector at Fermilab. In a sample of approximately 32 300 jets with a mean transverse energy of 47 GeV obtained from an exposure of 21.1 nb-1, a signal corresponding to 25.0±7.5(stat)±2.0(syst) D*±K events is seen above background. This corresponds to a ratio N(D*++D*-)/ N(jet) =0.10±0.03±0.03 for D* mesons with fractional momentum z greater than 0.1. © 1990 The American Physical Society
Measurement of the B-d(0)-(B)over-bar(d)(0) oscillation frequency RID C-4549-2008 RID C-5719-2008
No full textTime-dependent B-0-(B) over bar(0) mixing is studied using about two million hadronic Z decays registered by L3 in 1994 and 1995. For this study three techniques are used. Tagging of the b-quark charge at decay time is performed by identifying leptons from semileptonic B decays. The flavour of the b quark at production time is determined from the charge of the lepton in the opposite hemisphere or by using a jet-charge technique. The proper time of the B-particle decay is obtained by reconstructing the production and decay vertices or by a measurement of the lepton impact parameter. The combined result for the frequency of B-d(0) meson oscillations is Delta m(d) = 0.444 +/- 0.040 ps(-1)
Search for -meson production in p-p interactions at a centre- of-mass energy of 53 GeV
No full textA search for D(1.87) mesons produced at x approximately 0.1 at the CERN ISR gave a null result. Cross-section upper limits of 9 mu b and 8 mu b at the 95% confidence level were measured for the processes p+p to D/sup 0/+X, D/sup 0/ to K/sup -/+ pi /sup +/, and p+p to D/sup 0 /+X, D/sup 0/ to K/sup +/+ pi /sup -/, respectively. Production of f /sup 0/(1270) was observed with a cross-section of 1.9+or-0.4 mb. (12 refs)
