Orient-Occident Croisements lexicaux et culturels. Actes des Quatrièmes Journées italiennes des Dictionnaires, Naples, 26-28 février 2009
No full textLo studio del lessico, misura di ogni cosa secondo Alain Rey, permette di registrare il ritmo dell’evoluzione della società, esprimerne le conoscenze, comunicare le nuove esperienze. A partire da questa premessa, il volume presenta una ricerca sulla lessicologia e sulla lessicografia, due scienze che proprio il lessico hanno in oggetto, sebbene con fini e metodi diversi, complementari e interagenti. Si tratta del primo risultato delle ricerche condotte su tali assunti

Giovanni Fusco musicista per il cinema di Antonioni

Possibilistic Network. Social Polarization in the Metropolitan Area of Marseille (France).
No full textThis R-script builds and executes a possibilistic network which has the same structure as the Baysesian network proposed by F. Scarella [2] in order to model social polarization in the metropolitan area of Marseille (France). The model can be used to infer a trend scenario of social polarization of the 439 municipalities in the metropolitan area of Marseille (France) in a 10 year time. Within the model, a valorized municipality is defined as a municipality where executives and professionals are overrepresented within its resident population; a devalorized municipality is defined as a municipality where the unemployed are overrepresented within its resident population.
The initial data for the study area were elaborated for 2009 and are in the Data_Marseille_2009.txt file. Other auxiliary files are:
- DependentVariables.txt containing the dependency structure of the possibilistic network
- VariableModalities.txt containing the values of each variable of the network
- VariableModalities_PlainEnglish.txt gives plain English names to variables and modalities, but is not used by the R-script.
- ModelStructure.png visualizes the DAG structure of the possibilistic network
The network is build using uncertain logical gates ([3], [4]), which are the possibilistic counterpart of the noisy logical gates used in Bayesian networks [2]. More thorough presentations of the model and of the model results are available in [5] and in [6].
Model results and comparison with Bayesian network results can be explored through an interactive data-visualization at the following address: https://public.tableau.com/profile/fusco#!/vizhome/RepresentingUncertainFutures/Story1

No full textRobust feedback stabilization by means of Lyapunov-like functions determined by Lie brackets
No full textWe use Lie brackets of unbounded vector fields to consider a dissipative relation that generalizes the differential inequality which defines classic control Lyapunov functions. Under minimal regularity assump- tions, we employ locally semiconcave solutions of this extended relation, called in the following degree-k control Lyapunov functions, in order to design degree-k Lyapunov feedbacks, i.e. particular discontinuous feedback laws that stabilize the underlying system to a given closed target with compact boundary, in the sample and hold sense. We also prove that this feedback construction is robust when small measurement errors and external disturbances occur
Gap Phenomena in Optimal Control with State Constraints
No full textWhen existence of minimizers of an optimal control problem is not guaranteed, it is a common practice in Control Theory to extend the set of admissible solutions, so that to construct an auxiliary optimization problem that admits minimizers. The first fundamental requirement of such an auxiliary problem for it to be well posed is the density (e.g. in the L∞-norm) of the set of trajectories of the original system into that of the auxiliary one. Nevertheless, due to the presence of constraints, it might happen that the minimum of the auxiliary problem is strictly smaller than the infimum of the original one. We refer to this phenomenon as infimum gap.
In the literature, sufficient conditions for no gap are sometimes expressed in terms of normality of the sets of multipliers of the Maximum Principle. However, in the common situation of active state constraints at the initial point, there always exist degenerate – consequently, abnormal – sets of multipliers.
In this thesis, we establish a gap-abnormality relation for a general auxiliary prob- lem that comprehends as special cases both the compactification of the control set and the convexification of the dynamics in a novel unified framework. Furthermore, we provide refined no infimum gap conditions in order to deal with the presence of state constraints. In particular, under a suitable constraint qualification condition, we prove that if the minimizer of the auxiliary problem is a nondegenerate normal extremal, i.e. it is normal in the subset of nondegenerate multipliers only, then there is no infimum gap.
We highlight the relevance and novelties of our results with several examples, and we analyze in detail the special case of control-polynomial impulsive optimization problems.When existence of minimizers of an optimal control problem is not guaranteed, it is a common practice in Control Theory to extend the set of admissible solutions, so that to construct an auxiliary optimization problem that admits minimizers.
