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
Recensione di Daniele Vecchiato: Versi per dopodomani. Percorsi di lettura nell’opera di Durs Grünbein
No full textDaniele Vecchiato offers a clear excursus on the reception of Durs Grünbein. This is the first study in Italy about this famous contemporary author that was also influenced greatly by Italian culture and literature
Daniele 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

Design of an efficient 900 GHz antenna in standard CMOS technology for imaging arrays
No full textThis paper describes and addresses the challenges that are encountered while designing a 900 GHz antenna for FET detectors using a standard submicron CMOS technology. The reduced metal stack, the problem of surface waves and technology-related rules are taken into account in order to properly design an efficient antenna, with the objective to couple it to field-effect transistor (FET) detectors in a focal-plane array configuration. Simulations on a 0.15-μm standard CMOS technology show that up to 58% efficiency with responsivity in the several kV/W range can be achieved.Accepted author manuscriptTera-Hertz Sensin

Turbulent-boundary-layer trailing-edge noise reduction technologies including porous materials
No full textNoise reduction is one of the major challenges to the societal acceptance of wind turbines. Aerodynamic noise sources are the dominant ones, assuming that mechanical noise can be reduced by correct insulation and periodic maintenance of the gearbox and drive train and by adding insulating material in the wind-turbine nacelle. The dominant aerodynamic noise source is turbulent boundary layer trailing edge noise, caused by the scattering of the pressure fluctuations beneath the turbulent boundary layer at the trailing edge of an airfoil. In order to reduce this source of noise, several strategies have been proposed such as: optimized airfoil design for noise performances; installation of add-ons such as brushes or trailing-edge serrations; and recently, permeable materials at the trailing edge. In this chapter, after a brief introduction to the aerodynamic noise sources, the noise reduction physical mechanisms of trailing-edge serrations, as an industrial state-of-the-art solution, and of porous materials, as an innovative noise reduction strategy, will be discussed.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Wind Energ
In cerca di Giovanni Francesco Crivelli
No full textA partire da un dipinto firmato, raffigurante la "Madonna col Bambino in trono e due angeli", l'articolo restituisce corpo alla problematica personalità del pittore Giovanni Francesco Crivelli, attivo in area adriatica a cavallo tra XV e XVI secolo. La ricerca sull'artista, avviata da Federico Zeri, si è incrementata grazie alle precisazioni recate dall'Autore.Starting with a signed painting depicting the "Madonna and Child Enthroned and Two Angels", the article gives body to the problematic personality of the painter Giovanni Francesco Crivelli, active in the Adriatic area at the turn of the fifteenth and sixteenth centuries. The research on the artist, started by Federico Zeri, has increased thanks to the clarifications brought by the author
Google Maps Timeline: An open-access digital tool to monitor walking abilities in people with multiple sclerosis
No full textIntroduction: Gait impairment is common in multiple sclerosis (MS), but difficult to evaluate in clinical practice. In this proof-of-concept observational study, we compared walking ability recorded by Google Maps Timeline to conventional clinical measures in people with MS. Methods: We used open-access Google Maps Timeline to record the total number of days with walking activity, walking distance, walking time, and walking speed. Each Google Maps Timeline variable was included in a different stepwise linear regression model including all conventional clinical variables. Results: We included nine people with MS (age 43.1 ± 6.6 years; females 55.6%; disease duration 12.7 ± 3.1 years; median Expanded Disability Status Scale 3.0 (range 1.0-5.5)). Higher percentage of days with recorded walking was associated with lower Fatigue Severity Scale (p = 0.01), and higher MS Walking Scale (p = 0.04). Longer average daily walking distance was associated with shorter Timed-25 Foot Walking Test (p = 0.02), lower Expanded Disability Status Scale (p = 0.01), and higher Euro-Quality of Life (p = 0.04). Longer average daily walking time was associated with shorter Timed-25 Foot Walking Test (p = 0.03). Higher walking speed was associated with lower Fatigue Severity Scale (p = 0.04). Conclusion: Google Maps Timeline parameters provide actual estimates of daily walking activities in MS
