No full textThe pictorial wit of Domenico Tiepolo
No full textThis thesis takes a new approach to Domenico Tiepolo’s (1727-1804), Divertimento Per li Regazzi (c.1795-1804), it is arguably the artists most enigmatic graphic work, which features the commedia dell’arte character Pulcinella. The drawings have hitherto been subject to rigorous connoisseurial analysis. Indeed, in his introduction to ten of the drawings in a catalogue of Italian Eighteenth-Century Drawings in The Robert Lehman Collection at the Metropolitan Museum of Art, New York, James Byam Shaw states that this particular series of drawings has now become so famous ‘that it is hardly necessary to add to the literature of the series.’1 In my opinion it would be a great pity if future generations of scholars were discouraged by this remark, for I believe the drawings still have much to ‘tell’ the contemporary art historian and would further benefit from increasingly interpretative readings. Previously, scholars have regarded Domenico Tiepolo as an imitator of his father, Giambattista Tiepolo (1696-1770), and interpreted the re-appropriation of motifs in the Divertimento as signs of old age and fatigue. I suggest, on the contrary, that in this series of drawings in particular, Domenico was an innovator.
This project carves out new territories within the study of the series in that it focuses on the playful nature of the drawings, and how the suite can be understood in relation to contemporary theory concerning games and play, and ludic musical/improvisatory forms. Additionally, the drawings are discussed as a case history in a now popular emerging dialectic on the late works of aged artists: here I consider how these drawings, often funny, poignant, sensitive and delicate reveal how the elderly painter reconciles himself not only to the passing of his own life and the extinction of his family line but to an entire political, cultural and visual tradition
A Self-Consistent Model of the OCVD Behaviour of Si and 4H-SiC P+-N-N+ Diodes
No full textA comprehensive analytical model of the open-circuit voltage-decay (OCVD) response for a generic diode, switched from an arbitrary forward-bias condition, is proposed. To properly account for the steady-state conditions of the diode, the dynamic model incorporates an accurate description of the static I- V curves, which turns also useful for better understanding the influence of physical parameters on voltage transitory. As shown from comparisons with simulations and experiments, the model accurately describes the spatial-temporal variation of carriers and currents along the whole epilayer and allows one to resolve some ambiguities reported in the literature, such as the stated inapplicability of the OCVD method on thick epilayers, the reasons of the observed nonlinear decay of the voltage with time, and the effects of junction properties on voltage transient

Experimental measurements of Majority and Minority Carrier Lifetime Profile in Si- epilayers by the use of an improved OCVD method
No full textIn this letter, the first experimental results of a recently proposed technique for measuring the carrier lifetime profile are presented. The technique makes use of a four-terminal bipolar test structure to electrically define the epilayer volume where recombination occurs and employs the open circuit voltage decay method for lifetime parameters extraction. For the capability of the test structure to depurate measurements from the parasitic ohmic effects, the technique is able to measure the ambipolar and minority carrier lifetime along epilayer at high and low injection levels respectively. Comparisons of measurements with numerical simulations are reported to confirm the validity of the proposed technique
Domenico Venier's Poetics and Petrarchism in Sixteenth-Century Veneto
No full textreservedIl presente elaborato si propone di indagare il fenomeno del petrarchismo cinquecentesco in area veneta, concentrandosi in particolare sulla figura di Domenico Venier, tra i più rappresentativi interpreti della lirica petrarchesca nel contesto veneziano del XVI secolo. Attraverso un’analisi delle principali istanze tematiche e stilistiche rintracciabili nella sua produzione poetica, la tesi intende delineare un profilo letterario dell’autore che tenga conto non solo della tradizione petrarchesca, ma anche delle caratteristiche culturali e sociali del contesto lagunare. Particolare attenzione è riservata al cenacolo venieriano, luogo privilegiato di scambio intellettuale e di sperimentazione poetica, che svolse un ruolo significativo nella diffusione e nella rielaborazione del canone lirico stabilito da Pietro Bembo nella prima metà del Cinquecento. La tesi prende inoltre in esame la ricezione critica della poesia di Venier, con l’obiettivo di ricostruire le diverse prospettive interpretative che hanno contribuito a delineare l’immagine letteraria del poeta nel corso dei secoli.This thesis aims to investigate the phenomenon of sixteenth-century Petrarchism in the Veneto region of Northern Italy, with a particular focus on the figure of Domenico Venier, one of the most prominent exponents of Petrarchan lyric poetry of the time. Through an analysis of the main thematic and stylistic features that characterize his poetic production, the study seeks to outline a literary profile of the author, considering not only the Petrarchan tradition but also the cultural and social characteristics of the Venetian context. Special attention is given to Venier’s social circle, a privileged space for intellectual exchange and poetic experimentation, which played a significant role in the dissemination and reworking of the lyric canon established by Pietro Bembo in the first half of the sixteenth century. The thesis also examines the critical reception of Venier’s poetry, aiming to reconstruct the various interpretative perspectives that have contributed to shaping the poet’s literary image throughout the centuries
A Novel Measurement Method of the Spatial Carrier Lifetime Profile Based on the OCVD Technique
No full textUsing an original test structure we show by numerical simulations that the open circuit voltage decay (OCVD) method can be improved to obtain the spatial profile of the /spl tau//sub PO/, /spl tau//sub NO/ lifetime parameters along the epilayer of n-n+ wafers. The test structure consists of a surface diode including an additional n/sup +/ region, where the diode is used to inject minority carriers within the epilayer, the sense region allows one to measure the diode voltage without the series resistance effect, and finally a positive voltage applied to the n+ substrate is used to electrically control the epilayer volume where carriers recombine
