Irreducibility of Hurwitz spaces of coverings with monodromy groups Weyl groups of type W(B_d)
2007
Let Y be a smooth, connected, projective complex curve of genus ≥0. R. Biggers and M. Fried [J. Reine Angew. Math. 335, 87–121 (1982; Zbl 0484.14002), Trans. Am. Math. Soc. 295, No. 1, 59–70 (1986; Zbl 0601.14022)] proved the irreducibility of the Hurwitz spaces which parametrize coverings of ℙ 1 whose monodromy group is a Weyl of type W(D d ). Here we prove the irreducibility of Hurwitz spaces that parametrize coverings of Y with monodromy group a Weyl group of type W(B d ).
Hybrid Observer for Indoor Localization with Random Time-of-Arrival Measurments
2018
In this work an indoor position estimation algorithm will be proposed. The position will be measured by means of a sensor network composed by fixed beacons placed on the indoor environment and a mobile beacon mounted on the object to be tracked. The mobile beacon communicates with all the fixed beacons by means of ultra wide-band signals, and the distance between them is computed by means of time of flight techniques. Moreover, inertial measurements will be used when the position measurements are not available. Two main problems will be considered in the proposed architecture: the fact that the beacons work with a lower update rate than the IMU, and that the mobile beacon can comunicate wit…
LOCAL MICROWAVE HYPERTHERMIA AND INTRAVESICAL CHEMOTHERAPY AS BLADDER SPARING TREATMENT FOR SELECT MULTIFOCAL AND UNRESECTABLE SUPERFICIAL BLADDER TU…
1998
Purpose: The role of a combined regimen of local hyperthermia and topical chemotherapy in patients with multifocal and recurrent superficial bladder tumors not curable by transurethral resection was evaluated in a neodjuvant organ sparing clinical study. Materials and Methods: A total of 19 patients with multifocal, superficial grades 1 to 3 bladder tumors that recurred after intravesical chemoprophylaxis or immunoprophylaxis underwent local combined administration of microwave induced hyperthermia and intravesical chemotherapy as a debulking approach. Due to extensive superficial involvement of the bladder walls complete transurethral resection of all tumors seemed technically unfeasible i…
Seismic Network Evaluation through Simulation: An Application to the Italian National Seismic Network
2011
Abstract A properly organized seismic network is a valuable tool for monitoring seismic zones and assessing seismic hazards. In this paper we propose a new method (seismic network evaluation through simulation, SNES) to evaluate the performance of hypocenter location of a seismic network. The SNES method gives, as a function of magnitude, hypocentral depth, and confidence level, the spatial distribution of the number of active stations in the location procedure and their relative azimuthal gaps, along with confidence intervals in hypocentral parameters. The application of the SNES method also permits evaluation of the magnitude of completeness ( M C ), the background noise levels at the sta…
Comparing local structures of spatio-temporal point processes on linear networks
2022
We employ the Local Indicators of Spatio-Temporal Association (LISTA) functions on linear networks to build a statistical test for local second-order structure. This allows to identify differences in the spatio-temporal clustering behaviour of two point patterns, a point pattern of interest and a background one, both occurring on the same linear network. We illustrate the proposed methodology analysing a traffic-related problem.
Inscrire les contrats en alternance dans une logique de parcours sécurisé : rapport d'évaluation
2012
Document en ligne sur le site de l'IREDU; Les avantages de l'apprentissage ne doivent pas masquer la réalité de ce mode de formation et les difficultés des jeunes qui peuvent apparaître dès le début du choix de l'alternance, ou au cours de leur cursus, et entraîner un abandon. Une action de tutorat externe et neutre menée par trois Missions locales auprès des apprentis et des employeurs peut contribuer à la sécurisation des parcours d'apprentissage, comme le montre l'expérimentation réalisée durant près de deux ans en Côte-d'Or, une expérience randomisée sous certaines conditions. Les publics ciblés étaient les jeunes entrés dans la vie active par le biais d'un contrat d'apprentissage dans …

Analysis of the IEEE 802.11e EDCA Under Statistical Traffic
2006
Many models have been proposed to analyze the performance of the IEEE 802.11 distributed coordination function (DCF) and the IEEE 802.11e enhanced distributed coordination function (EDCA) under saturation condition. To analyze DCF under statistical traffic, Foh and Zukerman introduce a model that uses Markovian Framework to compute the throughput and delay performance. In this paper, we analyze the protocol service time of EDCA mechanism and introduce a model to analyze EDCA under statistical traffic using Markovian Framework. Using this model, we analyze the throughput and delay performance of EDCA mechanism under statistical traffic.
Analisi dei rapporti tra finanza innovativa e distretti tecnologici. Il contributo delle banche locali nei distretti Italiani
2011
Questa Capitolo s’inserisce nell’ambito delle ricerche sui sistemi regionali di innovazione ed in particolare sui distretti tecnologici cercando di approfondire il ruolo che in essi svolge la finanza innovativa. La prima parte propone una rassegna della letteratura più recente volta a delineare un quadro interpretativo dei distretti tecnologici. La seconda parte contiene un’analisi econometrica di tipo panel su un campione di banche locali per individuare quali componenti afferenti alla struttura, alla rischiosità della loro clientela, all’efficienza tecnico-operativa e alla loro solvibilità abbiano avuto maggiori ricadute sulla capacità di diversificare il sistema di offerta. La terza par…
