Asynchronous discrete event schemes for PDEs

Asynchronous discrete event schemes for PDEs

A new class of asynchronous discrete-event simulation schemes for advectiondiffusion-reaction equations is introduced, based on the principle of allowing quanta of mass to pass through faces of a (regular, structured) Cartesian finite volume grid. The timescales of these events are linked to the flux on the face. The resulting schemes are self-adaptive, and local in both time and space. Experim...

Asynchronous parallel discrete event simulation

AbstructComplex models may have model components distributed over a network and generally require significant execution times. The field of parallel and distributed simulation has grown over the past fifteen years to accommodate the need of simulation the complex models using a distributed versus sequential method. In particular, asynchronous parallel discrete event simulation (PDES) has been w...

Distributed and Asynchronous Discrete Event Systems Diagnosis1

shows three interconnected supervision domains. Each domain is a networked system, in which alarms are collected at a single sensor (figured by a small black dot) and processed locally by the supervisor (shown as a larger grey circle). The different domains are interconnected by a network, figured by the popular “IP-cloud”. Communications are asynchronous, both within each domain and between do...

Fault Diagnosis for Distributed Asynchronous Dynamically Reconfigured Discrete Event Systems

Diagnosis of concurrent and asynchronous systems, such as large telecommunication or information systems, requires powerful mathematical models. The use of Petri net unfoldings allows to formalize diagnosis using partial order semantics, a generalization from the global state model imposed by the use of automata. If, in addition to asynchronicity and distribution, the network topology itself is...
