Modeling crowd dynamics through coarse-grained data analysis
2018
International audience; Understanding and predicting the collective behaviour of crowds is essential to improve the efficiency of pedestrian flows in urban areas and minimize the risks of accidents at mass events. We advocate for the development of crowd traffic management systems, whereby observations of crowds can be coupled to fast and reliable models to produce rapid predictions of the crowd movement and eventually help crowd managers choose between tailored optimization strategies. Here, we propose a Bi-directional Macroscopic (BM) model as the core of such a system. Its key input is the fundamental diagram for bi-directional flows, i.e. the relation between the pedestrian fluxes and d…
First demonstration of active plasmonic device in true data traffic conditions: On/off thermo-optic modulation using a hybrid silicon-plasmonic asymm…
2012
We demonstrate the first system-level evaluation of an active plasmonic device in 10Gb/s data traffic conditions. Thermo-optic ON/OFF modulation with 3μs response time and 10mW power consumption is presented using an asymmetric MZI silicon-plasmonic gate.
A Rule-Based Multi-agent System for Local Traffic Management
2009
Road Traffic presents a high dynamism which makes necessary the development of traffic management and control strategies to improve traffic flows and more important, road safety. So it is needed the use of intelligent systems to support traffic organizations and road operators to cope with incidents. In this paper we introduce a local autonomous system for traffic management. This way, though there could be a breakdown in the communications between the local system and the TCC, the local system will be able to warn the road users in case of incidents. The system uses multiagent technology to work with the specific characteristics of traffic domain. The expert MAS system is ruled-based that …
Protection of trafficked people in Italy: policies, limits and challenges
2015
Purpose– The purpose of the article is to analyse the Italian anti-trafficking system by examining its effectiveness in the protection of trafficked people.Design/methodology/approach– The article examines the protection of trafficked people in Italy, focusing in particular on the implementation of Article 18 of the “Consolidated Act of Measures Governing Immigration and Norms on the Condition of Foreign Citizens” (Legislative Decree n. 286/1998), which provides victims with protection and a residence permit independent of their cooperation with the competent authorities in criminal proceedings against offenders.Findings– The article demonstrates that, though the Italian legal framework on …
I traffici illeciti nel Mediterraneo. Persone, stupefacenti, tabacco. Report Germania
2019
Il Report analizza il diritto penale tedesco relativo a quattro diversi tipi di traffico: il traffico di migranti, la tratta di esseri umani, il traffico di stupefacenti e il contrabbando di sigarette. Il Report fa parte di una più ampia ricerca ("The New Era of Smuggling in the Mediterranean Sea", NESMeS) volta ad analizzare i suddetti traffici illeciti nell'area del Mediterraneo, con particolare riguardo ai seguenti paesi: Germania, Grecia, Italia, Portogallo e Spagna. Insieme al Rapporto tedesco e ai Report dei singoli ordinamenti giuridici interessati, la ricerca NESMeS ha prodotto un Report criminologico e un libro finale ("I traffici illeciti nel Mediterraneo. Persone, stupefacenti, t…
An empirically grounded agent based model for modeling directs, conflict detection and resolution operations in air traffic management
2017
We present an agent based model of the Air Traffic Management socio-technical complex system that aims at modeling the interactions between aircrafts and air traffic controllers at a tactical level. The core of the model is given by the conflict detection and resolution module and by the directs module. Directs are flight shortcuts that are given by air controllers to speed up the passage of an aircraft within a certain airspace and therefore to facilitate airline operations. Conflicts resolution between flight trajectories can arise during the en-route phase of each flight due to both not detailed flight trajectory planning or unforeseen events that perturb the planned flight plan. Our mod…
Trafficking and labour exploitation in domestic work and the agricultural sector in Italy
2016
In Italy, as in many European countries, agriculture and domestic work are sectors characterised by high levels of irregular work without contract and with no respect of minimum pay, humane living conditions or access to basic services. Generalised informality however sometimes leads to cases of sever exploitation and outright human trafficking. This report focuses on the conditions that can lead from irregular work to abuse and trafficking in agriculture and domestic work – we question the cultural and economic aspects that make such situations possible. We also review the relevant legislation punishing exploiters and protecting victims with a view of identifying existing gaps and make sug…
Modèle dynamique multiniveau et holonique pour la simulation d'un système complexe à grande échelle avec environnement spatial : Application à la sim…
2020
Nowadays, with the emergence of connected objects and cars, road traffic systems become more and more complex and exhibit hierarchical behaviours at several levels of detail. The multilevel modeling approach is an appropriate approach to represent traffic from several perspectives. Multilevel models are also an appropriate approach to model large-scale complex systems such as road traffic. However, most of the multilevel models of traffic proposed in the literature are static because they use a set of predefined levels of detail and these representations cannot change during simulation. Moreover, these multilevel models generally consider only two levels of detail. Few works have been inter…

Interferenze e convergenze fra prostituzione e tratta nelle recenti proposte di incriminazione del cliente
2017
Il sesso a pagamento è un fenomeno fortemente eterogeneo: se la prostituzione volontaria è rivendicata come scelta dai c.d. sex worker, proprio lo sfruttamento sessuale costituisce una delle principali attività di lucro per i gruppi criminali che operano nel traffico di esseri umani. Di recente, in Europa, sembra riscuotere un certo successo la convinzione che l’incriminazione del cliente possa scoraggiare la « domanda » di persone da utilizzare nel mercato dello sfruttamento sessuale: oltre al modello svedese che punisce il cliente tout court, nella direttiva anti-trafficking si invitano gli Stati membri ad introdurre norme penali contro il cliente consapevole della condizione di soggiogam…
