The integration of physical systems through computing and networking has become pervasive, a trend now known as Cyber Physical Systems (CPS). Functionality in CPS emerges from the interaction of networked computational and physical objects. System design and integration are particularly challenging because fundamentally different physical and computational design concerns intersect. The impact ...

When a networked virtual reality system handles composite media audio and video as well as three dimensional computer graphics, the quality of the virtual space is also greatly affected by the currently available network and end system resources. In this paper, we discuss the architecture of a networked virtual reality system C3. We propose a new criterion called IoP(Importance of presence) for...

As networked multimedia systems have evolved over the recent years, sophisticated multimedia applications have emerged. Through this, a revolution in the transmission of multimedia information over wired and wireless communication technologies has transpired. Society is now becoming more dependent on such technologies, and these are used in almost every aspect of our daily lives, including: com...

With the continuing trend towards globalization and focusing on high value with low volume, the manufacturing system architecture is evolving from traditional centralised model to the distributed model and to the recent networked model. In the modern manufacturing environment, the manufacturing systems are in networked framework via a variety of networking communication systems integrating the ...

* Supported by the Netherlands Organisation for Scientific Research (NWO), project 638.003.407 (Value-based Business-IT Alignment) One of the main purposes of collaborative networks is to satisfy specific consumer needs, which one company cannot satisfy alone. With the opening of the internet in the 1990s the number of companies that collaborate by means of computer networks increased rapidly. ...

Over the years, research on software architecture has identified architectural styles. In this paper we consider five of such styles, and analyze whether these styles can also be found in business value models for networked enterprises. To this end, we analyze 17 evalue models, as discussed in 29 academic papers or book chapters. We also consider whether the quality attributes related to the so...

The performance of a networked control system (NCS) is affected directly and indirectly by time delays generated in network communication. This paper addresses these time delays, their effects on system performance, and the measures taken in an NCS design. For a time delay which is random but less than one sampling interval T, we model the system as a time-invariant control system with constant...

In the globalized economies e-permeation has become a basic condition in our everyday lives. ICT can no longer be understood solely as artefacts and tools and computer-related literacy are no longer restricted to the ability to operate digital tools for specific purposes. The network society, and therefore also eLearning are characterized by fluidity and the key competence for social actors in ...

Many techniques for the enhancement of the quality of control have been studied in the networked control systems based on differentiated services, synchronization or dynamic aproaches. By controlling the resources of the network, a compromise between the offered quality of service and the required quality of control can be established. In the case of a multi hop control loop, using IEEE 802.15....
