Replication is a powerful technique for increasing availability of a distributed service. Algorithms for replicating distributed services do however face a dilemma: they should be (1) efficient (low latency), while (2) ensuring consistency of the replicas, ...
The purpose of the paper is to present our approach for specifying system behavior. Our approach is based on operation schemas and a system interface protocol (SIP). Operation schemas describe the functionality of system operations by pre- and post-conditi ...
We present new interaction and visualization paradigms relying on free form surfaces for studying and exploring human anatomy. We propose an interface for building three-dimensional anatomical scenes incorporating 3D anatomical organ models, freely orienta ...
The limitations of client/server systems become evident in an Internet-scale distributed environment. Peer-topeer (P2P) systems offer an interesting alternative to traditional client/server systems: Every node acts both as a client and a server and “ ...
Despite advances in implementation technologies of distributed systems during the last few years, little progress has been made on specification techniques for describing distributed systems in software development practice. The contribution of this paper ...
Presents a new architecture for simulating virtual humans in complex urban environments. The approach is based on the integration of six modules. Four key modules are used in order to manage environmental data, simulate human crowds, control interactions b ...
Window based network flow control protocols, such as TCP, modulate the number of unacknowledged packets the protocol is allowed to have outstanding. Such protocols change the window size when they receive positive or negative acknowledgments, where the lat ...
Window based network flow control protocols, such as TCP, modulate the number of unacknowledged packets the protocol is allowed to have outstanding. Such protocols change the size when they receive positive or negative acknowledgements, where the latter ki ...
By extending the system theory under the (min,+)-algebra to the time varying setting, we solve the problem of constrained traffic regulation and develop a calculus for dynamic service guarantees. For a constrained traffic regulation problem with maximum to ...
An optical method based on fluorescence spectroscopy was developed for in-situ non-destructive, real time, org. pollutant detection and quantification in soil. Optical fiber-based light-induced fluorescence probes allowing in-situ specific chem. detection ...
