"Gentlemen, I'm not happy" : Divagazioni su "Commento/Tormento"
No full textIn a paper published in "Eikasmos" 2005, pp. 409-418, "Commento/Tormento: eccessi antichi e moderni nell'esegesi dei classici", Mario Geymonat investigated the existing typologies of commentaries to the Classics, from Late Antiquity to our days. In this paper, the author examines the classification proposed by Geymonat, and draws attention to the possibilities of a new type of commentary in the Age of Internet
International Standards for the Induction Motor Efficiency Evaluation: a Critical Analysis of the Stray-Load Losses Determination
No full textMotor efficiency has to be measured or calculated in accordance with international standards. The most important standards are the IEEE 112-B, IEC 34-2, and JEC 3 . In this paper, a comparison of the measurement procedures defined by these international standards is reported, together with some comments on the prescribed methodologies. The comparison is based on experimental results obtained by tests on four general-purpose three-phase induction motors. The stray-load loss measurement represents a critical key for the correct evaluation of the motor efficiency. For this reason, a critical analysis of this type of losses has been performed. In particular, in order to understand which are the most critical quantities that influence their evaluation, the stray-load loss sensitivity to the measurement errors is analyzed. In the final part of the paper the temperature influence, on the conventional iron losses, is experimentally analyzed. The performed tests show that the temperature difference between the no-load test and the motor real operative conditions is not negligible
Un nuovo disegno di Mario Asprucci per il Museo dei Gabi in Villa Borghese
No full textL'autore ricostruisce le vicende della progettazione del Museo dei Gabi in Villa Borghese a Roma alla luce di un inedito, quanto importante, disegno di presentazione attribuito a Mario Asprucci. Le vicende, legate alla musealizzazione delle statue ritrovate a Gabi da Gavin Hamilton nel Pantano dei Grifi, permette di precisare la complessità dell'elaborazione del linguaggio neoclassico da parte dell'architetto Asprucci. Inoltre l'autore analizza l'album dei disegni del Museo dei Gabi del Museo di Roma di Palazzo Braschi, già attribuito a Giuseppe Valadier, attribuendolo più correttamente a Cristoforo Unterpregher.The author reconstructs the events of the design of the Gabi Museum in the Villa Borghese in Rome in the light of an unpublished, yet important, presentation drawing attributed to Mario Asprucci. The events, related to the musealisation of the statues found in Gabi by Gavin Hamilton in the Pantano dei Grifi, allow us to clarify the complexity of architect Asprucci's elaboration of neoclassical language. In addition, the author analyses the album of drawings in the Gabi Museum of Rome's Palazzo Braschi, formerly attributed to Giuseppe Valadier, attributing it more correctly to Cristoforo Unterpregher
Tra Darwin e Habermas. Sul caso e l'"indisponibilità" dell'individuo
No full textThis Essay is a follow up of a previous contribution to the study of some consequences of Darwin's thought in Moral Philosophy (Darwinismo morale, Pisa, 2002). Habermas' apprehension of a darwinian liberalism in our age is disputed, but the author agrees with him about the necessity of philosophically envisaging one important implication of contemporary technological development —namely, the implication of biotechnological possession, after the notion of «Körper haben» put forward by Helmut Plessner. This leads the author to reconsider a natural prerequisite of our idea of individual freedom (a prerequisite pretty much similar to the darwinian concept of chance), i. e. the asymmetry in responsibility between parents and their offspring, an asymmetry which is obviously affected by the possibility of pre–determining at least some features of it

Modelling soil-water interaction with the Material Point Method. Evaluation of single-point and double-point formulations
No full textMany problems in geotechnical engineering involve large deformations and soil-water interactions, which pose challenging issues in computational geomechanics. In the last decade, the Material Point Method (MPM) has been successfully applied in a number of large-deformation geotechnical problems and multi-phase MPM formulations have been recently proposed. In particular, there exist two advanced coupled hy-dro-mechanical MPM approaches to model the interaction between solid grains and pore fluids: the single-point and the double-point formulation. The first discretizes the soil-water mixture with a single set of ma-terial points (MP) which moves according to the solid velocity field. The latter uses two sets of MP one for the fluid phase and the other for the solid phase and they move according to the respective velocity field. The aims of this work is to present and compare the two theories, to emphasize their limitations and poten-tialities, and to discuss their applicability in the geotechnical field. To this end, the results of two numerical examples carried out by using both formulations are presented: a 1D-consolidation problem and a saturated column collapse problem
