Parameterization of invariant manifolds for difference equations including discrete Lagrangians Hector Lomeli Department of Mathematics, Instituto Tecnológico Autónomo de México Date and time: Thursday, March 31, 2011 - 4:30pm Abstract: We generalize some notions that have played an important role in dynamics (namely invariant manifolds) to the more general context...
A Chaotic Encryption Scheme Based on a 4-Dimensional Chaotic System Ashar Ali Applied Mathematics , University of Colorado Boulder Date and time: Thursday, March 10, 2011 - 4:30pm Abstract: Chaotic systems by definition exhibit sensitive dependence on initial conditions and have the capacity to display seemingly random behavior. Both of...
Why ignoring your Darwinian fitness may be adaptive: Evolutionary dynamics of movement strategies in the presence of realistic constraints Theodore Galanthay Applied Mathematics , University of Colorado Boulder Date and time: Thursday, March 3, 2011 - 4:30pm Abstract: In most theoretical habitat selection models, modelers assume that organisms tend to...
Robust and efficient algorithms for piecewise constant vector field topology Andrzej Szymczak Dept of Mathematical and Computer Science Date and time: Thursday, February 24, 2011 - 4:30pm Abstract: Development of robust methods of extracting stable features from datasets of various types is considered one of the fundamental problems in scientific...
Subcritical percolation on networks Dane Taylor Applied Mathematics , University of Colorado Boulder Date and time: Thursday, February 17, 2011 - 4:30pm Abstract: Percolation on networks has applications ranging from epidemic and information spreading to system robustness. Extending previous results restricted to directed or Markovian networks, we introduce a general...
Using Traits-based Approaches to Understand the Dynamics of Biodiversity and Productivity Colleen Webb Dept of Biology, Colorado State University Date and time: Thursday, February 10, 2011 - 4:30pm Abstract: Predicting changes in community composition and ecosystem function in a rapidly changing world is a major research challenge in ecology and...
Population physiology: an information theory perspective David Albers Dept of Biomedical Informatics, Columbia University Date and time: Thursday, February 3, 2011 - 4:30pm Abstract: In this talk I will introduce the notion of population physiology, or human physiology in the context where both: (i) medium to long time scale dynamics...
Noise-induced phenomena in one-dimensional maps Yuzuru Sato Dept. of Mathematics, Hokkaido University Date and time: Thursday, January 20, 2011 - 4:30pm Abstract: Problems of complex behavior of random dynamical systems are investigated based on numerically observed noise-induced phenomena in Belousov-Zhabotinsky map (BZ map) and modified Lasota-Mackey map with presence of...
Event Description: Colleen Webb, Biology Department, Colorado State University The Role of Spatial Modularity In Ecoststem Robustness In a general context, robustness in complex adaptive systems may be enhanced by intermediate levels of modularization. When thinking about ecosystems and spatial structure, this translates most simply to the level of aggression...
Event Description: Benjamin Jamroz, Research Associate, University of Colorado Boulder Reduced Modeling of the Magnetorotational Instability Accretion is a fundamental process in many astrophysical systems, in particular, black holes at the center of galaxies. There has been debate as to the cause of the angular momentum extraction necessary for accretion...
