Spreading control with speed constraints

42nd IEEE International Conference on Decision and Control (IEEE Cat. No.03CH37475), 2004
This paper investigates spreading control under speed constraints on the spreads. By an approach, which combines feedback theory and set-valued analysis, spreading control laws under speed constraints are derived by a selection procedure and their optimality with respect to norm is examined.

Spreading Speeds in Slowly Oscillating Environments

Bulletin of Mathematical Biology, 2010
In this paper, we derive exact asymptotic estimates of the spreading speeds of solutions of some reaction-diffusion models in periodic environments with very large periods. Contrarily to the other limiting case of rapidly oscillating environments, there was previously no explicit formula in the case of slowly oscillating environments.

Spreading speeds as slowest wave speeds for cooperative systems

Mathematical Biosciences, 2005
It is well known that in many scalar models for the spread of a fitter phenotype or species into the territory of a less fit one, the asymptotic spreading speed can be characterized as the lowest speed of a suitable family of traveling waves of the model. Despite a general belief that multi-species (vector) models have the same property, we are unaware

Seasonal influences on population spread and persistence in streams: spreading speeds

Journal of Mathematical Biology, 2011
The drift paradox asks how stream-dwelling organisms can persist, without being washed out, when they are continuously subject to the unidirectional stream flow. To date, mathematical analyses of the stream paradox have investigated the interplay of growth, drift and flow needed for species persistence under the assumption that the stream environment ...

Estimating the Persistent Spreads in High-Speed Networks

2014 IEEE 22nd International Conference on Network Protocols, 2014
The persistent spread of a destination host is the number of distinct sources that have contacted it persistently in predefined t measurement periods. A persistent spread estimator is a software/hardware component on a router that inspects the arrival packets and estimates the persistent spread of each destination.
