Abbiamo unito le risorse elettroniche: ACNP e NILDE in Ateneo

L’idea della gestione di un servizio di Document Delivery (DD) sulle risorse elettroniche (ER) non è nuova, ma il modello sperimentato all’Università di Torino presenta delle innovazioni ed ha soddisfatto pienamente tutti i partecipanti. Il servizio è stato strutturato in modo distribuito ma coordinato: l’adesione volontaria e la disponibilità a sottoscrivere una carta comune del servizio, oltre all’impegno a registrare in NILDE tutte le transazioni per agevolarne la misurazione, sono tra le peculiarità del progetto. Il vantaggio del modello è la piena valorizzazione del ruolo delle biblioteche che, scegliendo di aderire, ottengono una riduzione del rischio di forti scompensi di debito sul sistema NILDE, grazie alla disponibilità per il DD dei titoli migrati al solo formato elettronico; hanno altresì una standardizzazione del servizio, la diffusione di buone pratiche e un maggiore rispetto delle licenze d’uso. Tra gli impegni dei partecipanti c’è inoltre l’assunzione di responsabilità sulla stabilità degli accessi ed il controllo delle consistenza su ACNP. Grazie alla gestione del servizio tramite NILDE si è avuta la possibilità di misurare la circolazione delle ER. Il confronto tra due periodi, pre- e post-sperimentazione, dimostra come l’inserimento delle ER nel catalogo ACNP abbia incrementato il numero delle transazioni del nostro Ente. Nonostante l’aumento della mole di lavoro il numero delle biblioteche che hanno deciso di continuare e/o iniziare ad offrire questo servizio per il network è incrementato. L’unica defezione registrata è dovuta a problemi di struttura.The idea of an electronic resource (ER) document delivery (DD) service is not new, but the model developed and tested at Università di Torino contains some new features and fully satisfied all the participants. It was structured as a distributed, but coordinated, service, with a voluntary participation and the availability to subscribe a communal charter of service and the commitment to record all the transactions into NILDE, in order to allow them to be measured. The plus (value ?) of the model is that it fully develops the role of the subscribing libraries, so reducing for them the risk of significant unbalance in NILDE, due to the upcoming unavailability of paper resources translated into electronic format. Moreover, the model standardises the service, so spreading good practices in respecting the clauses of the ER licences. Among the commitments of the participants, there is the responsibility to verify the stability of the access to the ERs and their consistency in ACNP. Recording the ER transactions allowed the ER circulation to be measured. The comparison of the ER transactions during method test period to those of a corresponding previous period shows how including ERs into the ACNP catalogue increased the overall transactions. In spite of the increase in the work load, the number of libraries that decided to continue or enter the project increased. The only leave was due to a structure organisation change

A Method to Support Diagnostics of Dynamic Faults in Networks of Interconnections

The article is devoted to the method facilitating the diagnostics of dynamic faults in networks of interconnection in systems-on-chips. It shows how to reconstruct the erroneous test response sequence coming from the faulty connection based on the set of signatures obtained as a result of multiple compaction of this sequence in the MISR register with programmable feedback. The Chinese reminder theorem is used for this purpose. The article analyzes in detail the various hardware realizations of the discussed method. The testing time associated with each proposed solution was also estimated. Presented method can be used with any type of test sequence and test pattern generator. It is also easily scalable to any number of nets in the network of interconnections. Moreover, it supports finding a trade-off between area overhead and testing time

New Structure of Test Pattern Generator Stimulating Crosstalks in Bus-type Connections

The paper discloses the idea of a new structure for a Test Pattern Generator (TPG) for detection of crosstalk faults that may happen to bus-type interconnections between built-in blocks within a System on a Chip structure. The new idea is an improvement of the TPG design proposed by the author in one of previous studies. The TPG circuit is meant to generate test sequences that guarantee detection of all crosstalk faults with the capacitance nature that may occur between individual lines within an interconnecting bus. The study comprises a synthesizable and parameterized model developed for the presented TPG in the VLSI Hardware Description Language (VHDL) with further investigation of properties and features of the offered module. The significant advantages of the proposed TPG structure include less area occupied on a chip and higher operation frequency as compared to other solutions. In addition, the design demonstrates good scalability in terms of both the hardware overhead and the length of the generated test sequence

Performance Evaluation of Organizational Crisis Cell: methodological proposal at communal level.

International audienceCrisis management has become an essential activity for all public and private organizations. Crisis management is most often based on a specific tool called "crisis cell". This paper aims to implement the precautions of anticipation, vigilance and intervention to meet the targets. Recent studies indicate that for over 50 years, catastrophic events have increased. In France, the crisis management plans are deployed to ensure an optimal state of readiness in case of a crisis. However, these plans do not guarantee optimal performance of crisis units. Crisis cells may become particularly vulnerable, and unable to fulfill their missions according to each event. This article proposes a method, primarily based on systems thinking to understand the vulnerability of the crisis cell and assess the performance of crisis management at the municipal level

Multi-Agents Model Oriented Safety in Maintenance (MAM-SM)

International audienceThis paper proposes an agent-based simulation framework for the development of a decision support system for occupational risks management in a maintenance task. The proposed model is defined as a Multi-Agent system oriented Safety in Maintenance (MAM-SM). This model aggregates many agents, where architecture includes agents Supervisor, Resource, Machine, Environment, Reasoning, Task, Control and Agent Capitalization. Based on a multi-agent simulator, the objective of the proposed approach is to account for the complexity of the maintenance task for better analysis and understanding of risks. It allows orienting the actors to the best decisions in order to minimize risks that may arise. The method is applied to two case studies. The results show that this model can express the behavior of each agent and also the performance of the whole system. In particular, the results demonstrate that the maintenance tasks can be controlled to avoid an accident

Dynamic Analysis of Safety Performance Indicators for CO2 Capture, Transport and Storage Activities

We are grateful to the publisher of Chemical Engineering Transactions, for letting this publication being archived in this Open Access repository. The publication is available at: http://dx.doi.org/10.3303/CET1226025International audienceCapture, Transport and storage of CO2 (CTSC) is a novel technology for mitigating CO2 emissions in the atmosphere and reduce the climate change impacts on ecosystems, human beings and natural resources. However, potential technical, environmental, health, safety and social risks associated with CTSC activities should be studied in order to reassure the stakeholders that CTSC will not have adverse effects on human beings and environment. CTSC can be considered as a complex sociotechnical system, for which traditional risk management approaches are not appropriate. An integrated approach is required for risk management of CTSC. The integrated approach should cover the interactions of capture, transport and storage, as well as the technical, organizational and human aspects of risk. The purpose is to evaluate the performance of safety control system in CO2 Capture, Transport and Storage chain. The idea is to develop a dynamic risk management framework by modeling the principal variables that are significant in terms of safety of CTSC, and study the evolution of these variables over time. These variables can be the ones that are integrated into the Safety Management System (SMS) in order to implement them into a scorecard containing the variation of key performance indicators over time, both in normal operation of the system, and in case of a failure. In this context, system dynamics is used for modeling. The model will allow us to know how the interaction of different variables (technique, organizational or human) may result in variation of performance indicators. The proposed methodology is based on eight steps that will be presented in the paper. The proposed framework is applied to an integrated CTSC project with an enterprise as the owner, and several firms and organizations as operators, designers and stakeholders. In this paper, the approach will be explained in detail and some preliminary results will be presented

Vulnérabilité du territoire: caractérisation et implémentation en gestion de crise

International audienceCe chapitre a pour objectif de présenter les éléments recueillis et analysés pour évaluer la vulnérabilité du territoire s'étendant de Nice à Savona face au risque d'accident de TMD et des conséquences associées. Une définition de la vulnérabilité territoriale est proposée à partir d'une analyse de modèles et d'indice de vulnérabilité. Le premier point s'attache ainsi à définir le concept de vulnérabilité. Le deuxième point aborde les différents seuils de vulnérabilité biophysique caractéristiques des enjeux humains et des structures recueillis auprès d'organismes et centres de recherche nationaux et internationaux réalisant des études toxicologiques et de résistance des matériaux. Le troisième point décrit le territoire d'étude, les flux de marchandises dangereuses qui le traversent sur ses axes routiers et présente les éléments considérés comme vulnérables face aux conséquences d'accidents de TMD à proximités des voies d'accès. Enfin, la dernière partie propose une définition de la vulnérabilité territoriale face au risque de TMD sur laquelle s'appuie le modèle général de réduction de la vulnérabilité proposé et qui sous-tend les travaux de recherche et développement présentés dans les chapitres successifs

Identification et reconnaissance automatique des TMD sur route et aide à la décision - Fiche 3

Rapport disponible sur : http://portail.documentation.developpement-durable.gouv.fr/dri/document.xsp?id=Drast-OUV00002030Etat de l'art de la gestion concertée des transports de matières dangereuses aux niveaux régional et local. Projet d'étude et d'animation d'ateliers : la gestion des risques liés aux transports de matières dangereuses au niveau des agglomérations, élaboration de recommandations et d'outils méthodologiques, sous la coordination de Philippe BLANCHER et Sandrine MAILLET. Programme national de recherche et d'innovation dans les transports terrestres. Lyon : ASCONIT Consultants, Saint-Etienne : CIRIDLe Pôle Cindyniques de l'Ecole des Mines de Paris mène des études sur l'apport de l'imagerie pour l'identification et la reconnaissance automatique des TMD sur route. Dans ce cadre, il collabore avec la société d'autoroute ESCOTA pour le développement d'un prototype sur une barrière de péage (voie " camion "). A partir des images acquises par le prototype et des traitements effectués par le logiciel d'identification et de reconnaissance, il est possible de connaître, à un temps t ou pour une période précise, le nombre et le type de matières dangereuses ayant transité sur le site concerné. Ces informations sont aussi utilisées dans le cadre de simulations pour estimer les dommages (population, bâtiments...) en cas d'accident TMD. Par ailleurs, le Pôle Cindyniques coordonne un projet INTERREG III A Alcotra (TMDNIS) en partenariat avec l'Université de Gênes, concernant la gestion transfrontalière des TMD sur route et les risques associés. La contribution du partenaire italien porte en partie sur l'apport de technologies embarquées (GPS) pour le suivi des véhicules. Ce projet ambitionne aussi le développement conjoint d'un système d'aide à la décision à partir d'un modèle dynamique de risque TMD sur l'axe Nice -Imperia - Savona
