Advanced services for critical infrastructures protection
No full textIn this paper an overview of the first results of FP7 CIPRNet project is presented. Particularly, we demonstrate CIPRNet services for critical infrastructure protection (CIP) stakeholders. The role of the proposed services is to support decisions in the CIP domain. Moreover, those services are expected to serve as the underpinnings for the European Infrastructures Simulation and Analysis Centre (EISAC) which, similarly to the US NISAC, should provide operational services on CIP, for the benefits of CI operators, stakeholders and the Public Authorities committed to CIP. © 2015, The Author(s)
Human vulnerability mapping facing critical service disruptions for crisis managers
No full textSocieties rely on the exchange of essential goods and services produced by Critical Infrastructures (CI). The failure of one CI following an event could cause “cascading effects” on other CI that amplifies the crisis. Existing tools incorporate modelling and simulation techniques to analyze these effects. The CIPRNet tools go a step further by assessing the consequences on population in a static manner: people are located at their census home; their sensibility to a resource lack varies during the day. This paper improves human impacts assessment by mapping people mobility thanks to the DEMOCRITE project methodology. It focuses on location of people with regards to their activities and the time period (night/day, holidays), and discuss their sensibility to the lack of key infrastructure services. Human vulnerability maps of Paris area during periods of a working day time show the importance to take into account people mobility when assessing crisis impacts. © 2017, Springer International Publishing AG
“Hybrid orders” between terrorism and organized crime: The case of Al Qaeda in the Islamic maghreb
No full textThis article analyzes the “nexus” between terrorism and organized crime in the Sahel. The arguments animating recent debates can be grouped into two distinct positions: the apocalyptic approach, which tends to exaggerate the threat of terrorism and its links with organized crime, and the conspiratorial approach, which reveals how the specter of terrorism comes to be manipulated by a range of actors for their own particular interests. This study offers an alternative view: thus far the region has not been subject to the spread and consolidation of Islamist ideology but rather to hybrid orders that are a complex dynamic of instrumental adaptation on the part of Islamist terrorists, criminal organizations, and the local population
PROSIDIS: A special purpose processor for protein similarity discovery
No full textThis work presents the architecture of PROSIDIS, a special purpose processor designed to search for the occurrence of substrings similar to a given 'template string' within a proteome. The paper recalls the basis of the PHG tool, developed within the framework of the HADES project, which automatically designs a parallel hardware starting from recurrence equations. In this work we present a special purpose processor, designed by PHG, which faces the protein similarity discovery problem. Some results are given, reporting the time spent by several microprocessors and by the PROSIDIS processor to solve the same protein analysis problem. © 2003 IEEE
The contribution of NEISAS to EP3R
No full textThis paper summarises key attributes of the National and European Information Sharing and Alert System and its contribution to the European Public-Private Partnership for Resilience project, sponsored by the European Commission's Directorate-General Home Affairs as part of its European Programme for Critical Infrastructure Protection. © 2013 Springer-Verlag
High level synthesis for programmable devices: The HADES project
No full textFPGAs allow the implementation of very complex designs (∼1million of gates); they are good candidates to host special purpose systems designed to boost conventional computing architectures. Several computationally intensive algorithms are poorly supported by standard computing architectures, so the design of dedicated devices implementing the intensive parts of such algorithms could significantly speedup the overall performances. (Re-)programmability, allowing the reusing of the same chip for different applications and avoiding the costly and cumbersome design of ASIC systems, is a key issue for the design of specialized computing architectures. Further crucial factors for the success of FPGA based coprocessors are both the possibility of achieving significantly larger performances than those attainable with conventional processors and the ability to produce a working prototype in very short times. This work presents the results achieved in the HADES (HArdware DEsign in Scientific applications) project, aimed at automatically extracting parallelism from affine iterative algorithms and at generating the synthesizable VHDL which describes the parallelized version of the algorithm. In the paper, along with the global HADES design flow, we present two cases, from the signal processing and the proteomic domains, in which FPGA based designs allowed to significantly increase the overall system performances. Thanks to the nearly global automation of all the steps of the design flow, in both cases, a working prototype has been realized in one working week. © 2002 IEEE
Parallel tight-binding molecular dynamics code based on integration of HPF and optimized parallel libraries
No full textIn this paper we describe the parallelization of a molecular dynamics code, based on a Tight-Binding Hamiltonian, on a DMMP parallel platform. The data-parallel implementation has been carried out within the HPF framework, and tested on IBM SP2 architectures. The integration of an optimized parallel library routine (PESSL) for the full diagonalization of large symmetric matrices is also described. The scalability of this approach, the performance of the parallel code and that of the PESSL routine are shown. © Springer-Verlag Berlin Heidelberg 1998
