In this paper we describe an innovative system providing services for tourism based on Near Field Communication technology. This work is part of the SIESTA project, co-funded by the Tuscany Region in Italy, to develop applications relying on mobile phones to support tourists visiting cities of art. Near Field Communication mixes the functionalities of RFID systems with the communication capabilities...
In this article we discuss the realization of antenna gate structures for inductively coupled passive HF RFID systems. Antenna gates are currently used in several applications, from industrial tracking to access control: in these structures the identification process is realized with the use of more antennas disposed in a configuration that makes them similar to doors. Nowadays these structures can...
Coastal erosion represents one of the most significant environmental emergencies, due to the fact that it affects locations distributed all over the world, including tourist sites and urban centers. Several solutions have been studied during the last years, including the use of gravel beaches as shore protections against the effects of waves. These solutions seem to provide a good protection, but...
The IEEE 802.11e standard introduces QoS features for delivering multimedia applications in a WLAN environment. However, under heavy traffic loads, network saturation is easily achieved and consequently QoS performance are inevitably degraded. In this paper an admission control algorithm for resource sharing in a wireless LAN environment is proposed, with the aim at enhancing QoS support for real-time...
In the heterogeneous scenario of standards supporting the deployment of Interactive Television, interoperability seems to be the key issue to grant a deeper market penetration of the digital television in everyday life as well as adequate return of investments to the actors involved in the value chain. This paper presents an innovative architecture to support application interoperability across different...
The project foresees the erection of a 12 MWe hydrogen-fed gas turbine cycle able to couple high efficiency fuel utilization with low nitrogen-oxide emissions. The project will be put into practice at Enel's coal-fired Fusina power plant. The aim of a first demonstrative phase is to verify the correct operation of the gas turbine with pure hydrogen as fuel and to acquire know-how of hydrogen combustion,...
This paper shows how an innovative service for the consultation of cartographical data was realized, based on GIS technology and mobile phones through a packet-switched mobile network and interconnected to the Internet. In particular some e-government institutional services tourism-oriented, able to provide geo-referenced information, have been implemented
During the last years, 3G standardization activities lead to new directions both in network and service provisioning architecture. As a result, new concepts of service portability have been defined (i.e., virtual home environment - VHE) and new topics related to security issues are gaining a significant impact. Taking into account such an input, we moved to promote the development of a new generation...
