Approximate network loading and dual-time-scale dynamic user equilibrium [PDF]

Transportation Research Part B: Methodological, 2011
Abstract In this paper we present a dual-time-scale formulation of dynamic user equilibrium (DUE) with demand evolution. Our formulation belongs to the problem class that Pang and Stewart (2008) refer to as differential variational inequalities. It combines the within-day time scale for which route and departure time choices fluctuate in continuous

Computing Dual Time-scale Dynamic User Equilibria [PDF]

, 2010
In this paper we summarize a dual-time scale formulation of dynamic user equilibrium with demand growth due to Friesz et al (2008). This formulation belongs to the problem class that Pang and Stewart (2008) refer to as di§erential variational inequalities.

Stability issues in dual time scale systems

Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2002
The paper presents some results on global exponential stability of linear time invariant systems with different time scales. Once fast and slow subsystems are derived, and controllers synthesized using Reaching Law Approach, global closed loop stability is derived for the whole system using Lyapunov methods.

Dual time scale measurements of the multiexponential fluorescence decay of quinacrine mustard

Optics Communications, 1981
Abstract The fluorescence decay of Quinacrine Mustard has been measured with good accuracy by means of a dual time scale digitizer-averager. Least-squares analysis of the experimental data with appropriate statistical weights has been performed. Values of the time constants for three componets have been obtained.

Subnanosecond fluorescence waveforms measurements with a dual time-scale microprocessor-controlled averager

Review of Scientific Instruments, 1981
This paper presents a microprocessor-controlled apparatus for the measurement of fast fluorescence waveforms. This apparatus features a dual-time scale for the analysis of multiexponential decays. A sampling oscilloscope is used as the sampling device. The sampling time is externally controlled by means of a staircase reference voltage.

Dual-Time-Scale Ion Acceleration Dynamics in Hall Thrusters

Physical Review Letters
We report the first direct observation using a retarding potential analyzer of time-resolved ion energy distribution functions (IDFs) in a Hall thruster (HT) on two distinct time scales corresponding to the breathing mode (∼kHz) and the ion transit time oscillation (ITTO, ∼100  kHz).
