In this paper, we discuss various techniques for the efficient organization of a temporal coherency preserving dynamic data dissemination network. The network consists of sources of dynamically changing data, repositories to replicate this data, and clients. Given the temporal coherency properties of the data available at various repositories, we suggest methods to intelligently choose a reposi...

This paper presents work on piggyback cache validation (PCV), which addresses the problem of maintaining cache coherency for proxy caches. The novel aspect of our approach is to capitalize on requests sent from the proxy cache to the server to improve coherency. In the simplest case, whenever a proxy cache has a reason to communicate with a server it piggybacks a list of cached, but potentially...

this paper proposes a novel approach for coherent generators online clustering in a large power system following a wide area disturbance. an interconnected power system may become unstable due to severe contingency when it is operated close to the stability boundaries. hence, the bulk power system controlled islanding is the last resort to prevent catastrophic cascading outages and wide area bl...

The work of adhesion of bimaterial interfaces is commonly computed using quantum mechanical methods in which the two materials are strained into coherency. There is no relaxation of the coherency by the formation of an array of interfacial misfit dislocations, contrary to what is commonly observed for essentially all systems other than very thin films. In this paper, we investigate the errors i...

For many applications of scalable multicomputers with distributed memory it is desirable to provide transparent shared virtual memory. For such applications, the hardware and system software must maintain coherency among the local memories. Most existing coherency schemes for multicomputers manage memory uniformly at a single granularity of fixed size pages or cache blocks, leading to unnecessa...

Long used as a framework for abstract modelling of genetic regulatory networks, the Random Boolean Network model possesses interesting robustness-related behaviour. We introduce coherency, a new measure of robustness based on a system’s state space, and defined as the probability of switching between attraction basins due to perturbation. We show that this measure has both upper and random-case...
