Methods for Experimentally Determining Stiffness of a Multi-Axis Machining Centre
2019
This paper deals with global methods for experimentally determining the static stiffness of multi-axis machining centres. Different devices used for measuring deflection, in specific, are explored, where accuracy and usability are highlighted. The methods were tested on a 3-axis CNC milling machine, 2-axis trunnion table and a 6-DOF industrial robot.
La citoyenneté assignée à résidence. Le rôle du registre national belge dans un contexte d’hypermobilité.
2022
Cet article interroge le lien entre l’existence administrative et l’ancrage par le domicile, depuis la mise en place des registres de population durant la période révolutionnaire, jusqu’au contexte actuel caractérisé par la globalisation et l’hypermobilité. En effet, au cours des dernières décennies, le développement des moyens de transports et de communication ont amené une augmentation de la mobilité humaine. Pourtant, depuis ses prémices, la citoyenneté a toujours élu domicile.
A Saturation Model of the Synchronous Reluctance Motor and its Identification by Genetic Algorithms
2018
This paper proposes a complete saturation model of the Synchronous Reluctance Motor (Syn1231), accounting for both the self-saturation and cross-saturation effects. This model is based on an analytical relationship between the stator flux and current components, and is characterized by parameters presenting an interesting physical interpretation, differently from many other saturation model in the scientific literature. It proposes also an identification technique of such a model based on stand-still tests, without the need of locking the rotor. The proposed saturation model permits the complete description of the magnetic behaviour of the machine with 8 parameters, fewer than those require…
Oxygen consumption of F0 and F1 larval and juvenile European seabass Dicentrarchus labrax in resonse to ocean acidification and warming
2022
Ongoing climate change is leading to warmer and more acidic oceans. The future distribution of fish within the oceans depends on their capacity to adapt to these new environments. Only few studies have examined the effects of ocean acidification (OA) and warming (OW) on the metabolism of long-lived fish over successive generations. We therefore aimed to investigate the effect of OA on larval and juvenile growth and metabolism on two successive generations of European sea bass (Dicentrarchus labrax L.) as well as the effect of OAW on larval and juvenile growth and metabolism of the second generation. European sea bass is a large economically important fish species with a long generation time…
Identification and validation of quasispecies models for biological systems
2009
An identification procedure for biological systems cast as quasi-species models is proposed. Their identification is a challenging problem because of the bilinear dependence on the parameters and their physical constraints. The proposed solution is within the framework of set-membership identification. %The bilinear dependence on parameters of the model and their physical constraints make the present issue challenging. We determine an estimate of the model parameters together with their interval of variability (Uncertainty Intervals), taking into account all the physical constraints. Invalidation/validation is performed on the basis of the predictive capability of the estimated models. The …
Yeast ecology of vineyards within Marsala wine area (western Sicily) in two consecutive vintages and selection of autochthonous Saccharomyces cerevis…
2012
In this work, the yeast ecology associated with the spontaneous fermentation of Grillo cultivar grapes from 10 vineyards was analyzed from grape harvest till complete consumption of must sugars. The microbiological investigation started with the plate count onto two culture media to distinguish total yeasts (TY) and presumptive Saccharomyces (PS). Yeasts were randomly isolated and identified by a combined genotypic approach consisting of restriction fragment length polymorphism (RFLP) of 5.8S rRNA gene and 26S rRNA and sequencing of D1/D2 domain of the 26S rRNA gene, which resulted in the recognition of 14 species belonging to 10 genera. The distribution of the yeasts within the vineyards s…
Una > forma di detenzione per l'identificazione dei migranti. Note a margine del d.l. n. 13/2017
2017
L'articolo esamina il d.l. n. 13 del 17 febbraio 2017, convertito, con modifiche, nella l. 13 aprile 2017, n. 46, che ha introdotto una nuova forma di detenzione per i migranti che rifiutino di essere identificati. La riforma continua a porre numerose problematiche sul versante della tutela dei diritti umani.

An integrative approach to unravel the Ceratitis FAR (Diptera, Tephritidae) cryptic species complex: a review
2015
Abstract This paper reviews all information gathered from different disciplines and studies to resolve the species status within the Ceratitis FAR (Ceratitis fasciventris, Ceratitis anonae, Ceratitis rosa) complex, a group of polyphagous fruit fly pest species (Diptera, Tephritidae) from Africa. It includes information on larval and adult morphology, wing morphometrics, cuticular hydrocarbons, pheromones, microsatellites, developmental physiology and geographic distribution. The general consensus is that the FAR complex comprises Ceratitis anonae, two species within Ceratitis rosa (so-called R1 and R2) and two putatitve species under Ceratitis fasciventris. The information regarding the lat…
Identifier et évaluer les compétences dans le système éducatif : quels apports pour la recherche en education ?
2007
07077 - 176 p.; Après un bref rappel sur la fonction de production scolaire, nous nous attacherons à montrer l'intérêt de mieux en spécifier les résultats, en termes de compétences développées par les élèves notamment. Nous reviendrons, pour cela, sur la recherche d'une éventuelle définition de la notion de compétence, pour s'attarder plus particulièrement sur les mesures de la compétence proposées par les acteurs du système à différents niveaux : local, national ou international (chapitre I). Ceci nous amènera à mettre en parallèle, d'un point de vue méthodologique, les outils dont dispose le praticien avec ceux mis à la disposition du chercheur, qui s'avèrent peut-être plus complets, mais…
