MFD models and time delays; some consequences for identification

Adaptive identification of time delays in nonlinear dynamical models.

This paper develops an adaptive synchronization strategy to identify both discrete and distributed time delays in nonlinear dynamical models. In contrast with adaptive techniques for parameter estimation in the literature, the adaptive strategy developed here for time-delay identification invites more precise results that have physical and dynamical importance. It is analytically and numericall...

Some Queueing Models of Airport Delays

Air traffic delays presently cost the nation over 3 billion dollars per year. Models of the behavior of delays around airports can be used to direct improvements to areas that will have the greatest positive effect. They can also help in avoiding the creation of new or more restrictive bottlenecks in the sensitive areas of the air traffic system. Models can predict the effect on delays of chang...

Delay-Scheduled Controllers for Inter-Area Oscillations Considering Time Delays

Unlike the existing views that was introduced the existence of delay caused by the transmission of wide area measurement system data (WAMS) into the controllers input of the power oscilation damping (POD) by communication networks as a reason for poor performance of the POD controllers. This paper shows that the presence of time delay in the feedback loop may improve the performance of a POD co...

Some Models for Scheduling Parallel Programs with Communication Delays

The aim of this paper is to present and analyze models for designing parallel programs. In the context of some extensions of the most popular execution models (precedence graphs, dataflow, PRAM), we describe scheduling techniques which take into account the communication delays. We illustrate all these models by two families of representative precedence graphs, namely, grids and complete trees.
