Apprentissage implicite de régularités : Mise en évidence d'une différence d'apprentissage entre tâches motrices continues et discrètes
2005
This research is concerned with the implicit learning of regularities in continuous motor tasks (e.g., tracking tasks) and discrete tasks (e.g., Serial Reaction Time tasks). First, a reanalysis of Wulf and collaborator's studies, dealing with implicit motor learning, made it possible to highlight methodological problems and potential biases that provide alternative explanations for the apparent implicit learning obtained in their continuous tracking experiments. Indeed, by respecting a more rigorous methodology, it appears that it is quite difficult to obtain such learning in a continuous task. This led us to try to understand why it was easier to draw benefit from a repetition in a discret…
STRUCTURE, ENVELOPE AND TECHNOLOGICAL INNOVATION The reinforced concrete in the construction of very tall buildings
2014
Until the second half of the nineteenth century, ie until the Industrial Revolution, the building structures played static function and also protective function. In the course of time separating the combination goes. The introduction of iron leads to a progressive "innovation" of building structures. The first application of iron in construction dates back to the mid-nineteenth century. They were first made with cast-iron columns and beams in iron and later with particular types of steel. The architecture of the iron is a true regeneration of the way of building, the cities are filled with sophisticated solid structures and slim at the same time, it enhances the transparency of glass, it in…

Optimal recovery of a radiating source with multiple frequencies along one line
2020
We study an inverse problem where an unknown radiating source is observed with collimated detectors along a single line and the medium has a known attenuation. The research is motivated by applications in SPECT and beam hardening. If measurements are carried out with frequencies ranging in an open set, we show that the source density is uniquely determined by these measurements up to averaging over levelsets of the integrated attenuation. This leads to a generalized Laplace transform. We also discuss some numerical approaches and demonstrate the results with several examples.

Le reti tra avvocati per la partecipazione alle procedure pubbliche di affidamento di servizi legali
2019
L'articolo analizza le principali questioni giuridiche connesse alla possibilità - oggi offerta dall'art. 12 della l. n. 81/2017 - di stipulare contratti di rete tra liberi professionisti, ed in particolare tra avvocati, allo scopo di partecipare alle gare pubbliche di affidamento di servizi legali. L'A. si propone altresì l'obiettivo di valutare se ed in che misura il contratto di rete possa offrire vantaggi competitivi, in termini di partecipazione alle procedure con la pubblica amministrazione, rispetto alle differenti modalita` organizzative attualmente a disposizione degli avvocati (es. società, associazioni, associazioni temporanee, consorzi stabili professionali).
The b-chromatic number of power graphs
2003
The b-chromatic number of a graph G is defined as the maximum number k of colors that can be used to color the vertices of G, such that we obtain a proper coloring and each color i, with 1 ≤ i≤ k, has at least one representant x_i adjacent to a vertex of every color j, 1 ≤ j ≠ i ≤ k. In this paper, we discuss the b-chromatic number of some power graphs. We give the exact value of the b-chromatic number of power paths and power complete binary trees, and we bound the b-chromatic number of power cycles.
A simulation function approach for best proximity point and variational inequality problems
2017
We study sufficient conditions for existence of solutions to the global optimization problem min(x is an element of A) d(x, fx), where A, B are nonempty subsets of a metric space (X, d) and f : A -> B belongs to the class of proximal simulative contraction mappings. Our results unify, improve and generalize various comparable results in the existing literature on this topic. As an application of the obtained theorems, we give some solvability theorems of a variational inequality problem.
Unification of Graphs and Relations in Mizar
2020
Summary A (di)graph without parallel edges can simply be represented by a binary relation of the vertices and on the other hand, any binary relation can be expressed as such a graph. In this article, this correspondence is formalized in the Mizar system [2], based on the formalization of graphs in [6] and relations in [11], [12]. Notably, a new definition of createGraph will be given, taking only a non empty set V and a binary relation E ⊆ V × V to create a (di)graph without parallel edges, which will provide to be very useful in future articles.
