Rapid developments in networking technology over the past few years have lead to the emergence of distributed applications which incorporate continuous media data types such as digital video and audio. Such applications have stringent real-time synchronisation requirements which have been documented in the literature. However, little research has been carried out into suitable mechanisms to sup...

Many systems consist of a signal processing and a control dominated part. The interaction of the data processing functions and a large variety of system-level control functions are often complex and with far reaching consequences. Thus, an early analysis and assessment of this interaction in a system level model is desirable. We propose a heterogeneous cosimulation environment with Matlab for t...

This paper presents a 3D-distributed virtual environment, which allows for the creation of applications to enable multiple users to collaboratively interact in, and communicate about, a virtual world. This virtual environment is used to primarily support a flight simulator application by providing communications routines and networking synchronisation between the client and the server. Four ser...

In Electronic Support, it is well known that periodic search strategies for swept-frequency superheterodyne receivers (SHRs) can cause synchronisation with the radar it seeks to detect. Synchronisation occurs when the periods governing the search strategies of the SHR and radar are commensurate. The result may be that the radar is never detected. This paper considers the synchronisation problem...

Parallel programs running on shared memory multiproces sors coordinate via shared data objects structures To en sure the consistency of the shared data structures programs typically rely on some forms of software synchronisations Unfortunately typical software synchronisation mechanisms usually result in poor performance because they produce large amounts of memory and interconnection network c...

Many coordination phenomena are based on a synchronisation process, whose global behaviour emerges from the interactions among the individual parts. Often in Nature, such self-organising mechanism allows the system to behave as a whole and thus grounding its very first existence, or expected functioning, on such process. There are however cases where synchronisation acts against the stability o...

We extend the π-calculus with polyadic synchronisation, a generalisation of the communication mechanism which allows channel names to be composite. We show that this operator embeds nicely in the theory of π-calculus, we suggest that it permits divergence-free encodings of distributed calculi, and we show that a limited form of polyadic synchronisation can be encoded weakly in π-calculus. After...

− The accurate measurement of many power quality parameters using digital sampling techniques relies on synchronisation between the sampling system and the signal under analysis. If synchronisation is not available measurement errors result due to the difference in frequency of the digitised signal and that expected and based on the sampling clock of the measurement system. A method is presente...
