Mechanical power and segmental contribution to force impulses in long jump take-off
1979
Changes in total mechanical work, its partitioning into different energy states, mechanical power, force-time characteristics, force impulses of body segments and mass center's pathway characteristics during long jump take-off were investigated on four national and six ordinary level athletes. Both cinematographic and force-platform techniques were used. The data showed that the national level jumpers had higher run-up and higher take-off (release) velocities in horizontal and vertical directions. In addition, they were able to utilize efficiently the elastic energy stored in the leg extensor muscles at take-off impact. This was seen in high support leg eccentric and concentric forces, whic…
The design and implementation of Neuma, a collaborative Digital Scores Library - Requirements, architecture, and models
2012
This paper presents the design and implementation of the Neuma platform, a digital library devoted to the preservation and dissemination of symbolic music content (scores). Neuma is open to musicologists, musicians, and music publishers. It consists of a repository dedicated to the storage of large collections of digital scores, where users/applications can upload their documents. It also proposes services to publish, annotate, query, transform, and analyze scores. The long-term goal of the project is to enable an open and collaborative space where musician communities will be able to share music in symbolic notation. The project is organized around the French IRPMF institute (BnF–CNRS) whi…
La tutela del contraente debole nella platform economy
2018
Negli ultimi anni si è affermato un nuovo modello di attività produttiva nel quale piattaforme digitali mettono in contatto gruppi interdipendenti di agenti economici per facilitare lo scambio di beni e l’erogazione di servizi. Dinanzi a questa trasformazione nell’organizzazione d’impresa, nel coordinamento del lavoro e nella struttura dei mercati, il diffuso appello a stabilire un “terreno di gioco neutrale” diviene la premessa per proporre la deregolamentazione di interi comparti economici valorizzando la capacità di autogoverno delle piattaforme. Mentre le reazioni a queste proposte sono confinate quasi esclusivamente alla questione del lavoro, è mancata finora un’analisi più generale de…
A platform-independent software for the design and analysis of windings of rotating electrical machines
2014
In this paper the Authors present a highly modular and platform-independent software, being based on the MATLAB® programming environment, which is proposed as a valuable aid in the design and analysis of the windings of rotating electrical machines. Unlike the major part of the commercial software, the cases of both symmetric and asymmetric (unbalanced) windings with any number of phases are here considered. The software can perform a considerable amount of calculations in order to determine automatically the optimal structure of the winding starting from its specifications. It is also able to draw the winding map and gives the results of calculation for the harmonic winding factors. The re…
Platform switching on wide-diameter external hex implants: a finite element analysis.
2012
Objectives: The objective of this work was to use finite element analysis to compare the effect of forces coming to bear on abutments 4.1 or 5.0 mm in diameter connected to a 5.0 mm implant (i.e. with or without platform swit - ching). Study design: A 3D CAD model of a 5 x 11.5 mm external hex implant was developed, complete with a connection screw and either of two abutments, one 4.1 and the other 5 mm in diameter, to assess the influence of two loading conditions, i.e. 200 N loaded either axially or off center on the top of the abutment. Results and conclusions: In the symmetrically loaded models, greater stresses were transmitted to the bone in the area below the neck of the implant in t…
Thinking collaborative empowerment as a communication dispositive : the case of collaborative consumption’s online community services in a sustainabl…
2020
This thesis propounds an info-communicational approach of empowerment phenomenon in a market oriented context. In order to do so, we focus on discourses and communicational processes that refer to this very concept in “collaborative consumption” platforms’ framework. Massification of this type of services is accompanied by discourses emphasizing a socioecological “power” they would be carrying for consumers (as a more social and sustainable economy). We underline the gap between this utopia and the organizational reality of empowerment. First part of this thesis proposes to highlight this polysemic concept. The point is to problematize empowerment in tension between political communication …

The structure of western Sicily, central Mediterranean
2002
Western Sicily is part of the Sicilian chain, a sector of the SE-verging Alpine orogenic belt in the central Mediterranean. Interpretation of seismic reflection profiles, boreholes and recent inland geological data, have enabled us to assess the deep structural grain. A wedge of flat-lying Mesozoic–Miocene carbonate and terrigenous rocks (pre-Panormide nappes) is superimposed on NW-trending, 7–8 km thick, Mesozoic–Paleogene carbonate thrust ramps (Trapanese units), arranged in two structural levels extending from the Tyrrhenian coast to western offshore Sicily. Upper Miocene to Pleistocene terrigenous strata, often deformed, fill syntectonic basins above the thrust pile. The main tectonic t…
