Mobile multimedia in vesper virtual home environment

Authors
Oliveira, JM; Roque, R; Carrapatoso, E; Portschy, H; Hovanyi, D; Berenyi, I;

Publication
IEEE INTERNATIONAL CONFERENCE ON MULTIMEDIA AND EXPO, VOL I AND II, PROCEEDINGS

Abstract
This paper presents the most innovative aspects of a middleware architecture that enables the provision of advanced personalized services in a Virtual Home Environment context. Multimedia considerations to extend the architecture to support mobile multimedia in a ubiquitous access terminal and network environment are also included.

Service provision & resource discovery in the VESPER VHE

Publication
2002 IEEE INTERNATIONAL CONFERENCE ON COMMUNICATIONS, VOLS 1-5, CONFERENCE PROCEEDINGS

Abstract
In VESPER1, the concept of VHE is being implemented and validated through the provision of a VHE system and various services to make use of it. This paper describes one of these services and presents how it validates VHE architecture aspects related with service adaptation to terminals and network, connection establishment, service personalization, session continuity/mobility and service advertisement. The paper also discusses some VHE usage scenarios of the resource discovery feature, showing how it plays an important role particularly in what concerns the ubiquitous service availability through the VHE platform.

Supporting internet protocols in master-slave fieldbus networks'

FIELDBUS SYSTEMS AND THEIR APPLICATIONOS 2001 (FET'2001)

Abstract
In this paper we describe how to integrate Internet protocols (TCP/IP) into a typical hierarchical master-slave fieldbus network, supporting a logical ring token passing mechanism between master stations. The integration of TCP/IP in the fieldbus protocol rises a number of issues that must be addressed properly. In this paper we particularly address the issues related to the conveyance of IP Datagrams in fieldbus frames (fragmentation/de-fragmentation) and on how to support the symmetry inherent to the TCP/IP protocols in fieldbus slaves, which lack communication initiative.

SARATOV FALL MEETING 2002: OPTICAL TECHNOLOGIES IN BIOPHYSICS AND MEDICINE IV

Abstract
Spectronephelometric measurement techniques are :in the order of the day. We can apply these techniques to monitor the production of consumable fluids and to verify their quality. Products like Wine, Beer and Olive Oil for instance, are widely consumed over the world. These products do have a major role in people's dietary habits and their quality is of greater concern from day to day. If we can make use of a monitoring system that is able to perform measurements in situ, on line and in real time, then we will obviously have the capacity to improve quality. Particles that are suspended in consumable fluid samples interact with radiation by scattering it in almost all directions. If we can detect this scattered radiation, then we have information on the suspended particles. Making use on some Physical relations, we can transpose this information to physical parameters like Color and Turbidity.
