Research paper thumbnail of A financial and technological model for public regional broadband infrastructure

Networks 2008 - The 13th International Telecommunications Network Strategy and Planning Symposium, 2008

All the operators that wish to offer services to companies and private citizens can take advantage of this network, which allows them keeping their own operative independence while reaching the marginal areas in an effective way. This paper describes both financial and technological aspects of the successful development plan for a regional broadband infrastructure in Regione Friuli Venezia Giulia, Italy, evaluating costs and benefits of such long-term investments. Analyzing the regional project from a macro-economic point of view, the model appears to be attractive for all the involved stakeholders. Public intervention makes also the Region attractive to ICT operators, and more in general to investors.

Indeed, conventional authentication methodologies, consisting of knowledge-based systems that make use of something you know (e.g., username and password) and token-based systems that make use of something you have (e.g., identification card), are not able to meet the strict requirements of reliable security applications. Conversely, biometric systems make use of behavioral (extrinsic) and/or physiological (intrinsic) human characteristics, overcoming the security issues affecting the conventional methods for personal authentication. This book chapter provides an overview of the most commonly used biometric traits along with their properties, the various biometric system operating modalities as well as various security aspects related to these systems. In particular, it wi...

The introduction of new technologies for supporting crop management allows the efficiency and quality of production to be improved and, at the same time, reduces the environmental impact. Common strategies to disease control are mainly oriented on spraying pesticides uniformly over cropping areas at different times during the growth cycle. Even though these methodologies can be effective, they present a negative impact in ecological and economic terms, introducing new pests and elevating resistance of the pathogens. Therefore, consideration for new automatic and accurate along with inexpensive and efficient techniques for the detection and severity estimation of pathogenic diseases before proper control measures can be suggested is of great realistic significance and may reduce the likelihood of an infection spreading. In this work, we present a novel system-theoretic approach for ...

Research paper thumbnail of Bandwidth Estimation Algorithms For The Dynamic Adaptation Of Voice Codec

We present a new algorithm to control the resource utilization and to optimize the voice codec selection during SIP call setup on behalf of the traffic condition estimated on the network path. The most suitable methodologies and the tools that perform realtime evaluation of the available bandwidth on a network path have been integrated with our proposed algorithm: this selects the best codec for a VoIP call in function of the instantaneous available bandwidth on the path. The algorithm does not require any explicit feedback from the network, and this makes it easily deployable over the Internet. We have also performed intensive tests on real network scenarios with a software prototype, verifying the algorithm efficiency with different network topologies and traffic patterns between two SIP PBXs. The promising results obtained during the experimental validation of the algorithm are now th...

The former takes into account the quite stable and long lasting bandwidth occupation, whereas the latter takes into account the large number of packets routed along the same path. Many techniques have been proposed and standardized to face these requirements, but their application is often complex, expensive and sometimes limited by the need of agreements between network managers of the many networks and Autonomous Systems. This paper introduces IMFM (Integrated Multimedia Flows Management), an innovative, scalable, and extremely lightweight technique to provide routers deterministic and dynamic resource reservation and a fast forwarding table lookup. It is based on a distributed linked data structure that allows direct (searchless) access to entries in the routers ’ tables, extending the resource reservation algorithm REBOOK. Unlike conventional virtual circuits,...

Starting from a formal description of the lessons, the running code of the multimedia application is generated in standard formats, and provides a consistent and easy-to-navigate hypermedia structure. Automatic link generation provides reusability of the multimedia material after it is organized in the lesson structure. This approach will allow authors to create different context-based presentations starting from the expected skill of the target users. Advanced indexing schemes will be further available for dynamic and interactive hypermedia generation. The MTEACH research project is also developing a stable workspace for almost real-time multimedia production. Interfacing the teacher’s console with a multimedia processing unit, lessons and knowledge models can be directly...
