Col : A Data Collection Protocol for Vanet
2012
International audience; In this paper, we present a protocol to collect data within a vehicular ad hoc network (VANET). In spite of the intrinsic dynamic of such network, our protocol simultaneously offers three relevant properties: (1) It allows any vehicle to collect data beyond its direct neighborhood (i.e., vehicles within direct communication range) using vehicle-to-vehicle communications only (i.e., the infrastructure is not required); (2) It tolerates possible network partitions; (3) It works on demand and stops when the data collection is achieved. To the best of our knowledge, this is the first collect protocol having these three characteristics. All that is chiefly obtained thanks…

Statistical properties of general Markov dynamical sources: applications to information theory
2004
In \textitDynamical sources in information theory: fundamental intervals and word prefixes, B. Vallée studies statistical properties of words generated by dynamical sources. This is done using generalized Ruelle operators. The aim of this article is to generalize sources for which the results hold. First, we avoid the use of Grotendieck theory and Fredholm determinants, this allows dynamical sources that cannot be extended to a complex disk or that are not analytic. Second, we consider Markov sources: the language generated by the source over an alphabet \textbfM is not necessarily \textbfM^*.
Il piano economico finanziario nelle concessioni di servizi
2021
The motivational system contained in the sentence of the Council of State of 13 October 2020, n. 6168 suggests reflecting on the function performed by the economic and financial plan in the matter of service concession contract as well as on its possible qualification as an integral element of the economic offer presented by the economic operator
Gli operatori economici nel labirinto dei gravi illeciti professionali e il periodo triennale di esclusione dalla gara dall’accertamento definitivo
2019
In the presence of a difficult system, such as that of serious professional offences, art. 80, paragraph 5, lett. c), Legislative Decree no. 50 of 2016, this work aims, first of all, to identify possible solutions suitable for avoiding choices of exclusion from the tender, potentially arbitrary, by the station contractor and to ensure a tender procedure based on compliance with the principle of certainty of law and on the constitutional principles referred to in Articles 3, 41 and 117, paragraph 2 lett. e), Constitution. We then focus on the issue of the temporal relevance of serious professional offences, such as significant deficiencies in the execution of a previous procurement contract,…
Regularization Preserving Localization of Close Edges
2007
International audience; In this letter, we address the problem of the influence of neighbor edges and their effect on the edge delocalization while extracting a neighbor contour by a derivative approach. The properties to be fulfilled by the regularization operators to minimize or suppress this side effect are deduced, and the best detectors are pointed out. The study is carried out in 1-D for discrete signal. We show that among the derivative filters, one of them can correctly detect our model edges without being influenced by a neighboring transition, whatever their separation distance is and their respective amplitude is. A model of contour and close transitions is presented and used through…
