Modeling heterogeneous sources on multiple time scales

Proceedings of IEEE INFOCOM '96. Conference on Computer Communications, 2002
We develop parameters and results for a set of traffic models which emulate the traffic patterns at the packet and buffer levels. We show that traffic models at these levels are dependent on the network capacity as well as source-induced bottlenecks such as buffer reads and writes. We propose a pragmatic approach which uses three variations of a simple

On Multiple Time Scales and Collapsibility

Lifetime Data Analysis
In this anniversary issue I briefly review some work on the notion of collapsibility and indicate some lingering questions.

Multiple Integration on Time Scales

2016
Let \({\mathbb {T}}_i\), \(i\in \{1,2,\ldots ,n\}\), be time scales. For \(i\in \{1,2,\ldots ,n\}\), let \(\sigma _i\), \(\rho _i\), and \(\varDelta _i\) denote the forward jump operator, the backward jump operator, and the delta differentiation, respectively, on \({\mathbb {T}}_i\).

A multiple time scale minimum variance beamformer

IEEE International Conference on Acoustics Speech and Signal Processing, 1993
Expressions for mean output power and mean squared error are derived for the multiple time scale minimum variance beamformer in terms of adaptive degrees of freedom (DOF) and adaptation time scale when the same input data block is used to update weights and output.

A multiple time scale modularized adaptive beamformer

IEEE Transactions on Signal Processing, 1994
This paper analyzes the cascaded equivalent form of the minimum variance distortionless response (MVDR) beamformer. A unique feature of the modularized MVDR (M/sup 2/VDR) beamformer is the ability to distribute adaptive degrees of freedom (DOF) among beamformer stages.

Multiple Time Scale Systems, Time and Modeling

IFAC Proceedings Volumes, 1997
Abstract Time is analyzed from the point of view of time-varying dynamic systems and modeling. New time - light speed relationships are discovered. Comparisons with the Einstein principle and the Lorentz transformation are given. The new relationships appear inherent for time scaling of multiple time scale systems such as singularly perturbed systems.

Analysis of multiple time scales in a transistor amplifier

Physical Review E, 2005
It was shown previously in an experiment that when high frequency signals (on the order of 1 MHz) were injected into this low frequency amplifier, the nonlinearities of the pn junctions caused period doubling, chaos, and very low frequency oscillations (on the order of 1 Hz).

Multiple time scales for recurrences of Rydberg states

Physical Review A, 1993
An initially localized Rydberg wave packet, with [Delta][ital n][much lt][ital n], spreads uniformly over its entire classical orbit within a time much larger than the classical period [ital T][sub cl]. However, it eventually reassembles, with a hierarchy of recurrence times: ([ital n]/3+1/2)[ital T][sub cl], ([ital n][sup 2]/4+1/2)[ital T][sub cl ...

Multiple time scales and subsystem embedding in the learning of juggling

Human Movement Science, 2004
To gain insight into the multiform dynamics and integration of remote yet pertinent subsystems into the performance of complex perceptual-motor skills, we recently conducted a series of longitudinal and cross-sectional experiments on the acquisition of 3-ball cascade juggling in which we measured, next to the ball trajectories, postural sway, eye and ...
