APPM Department Colloquium - Mike Breed

Dec. 1, 2006

Event Description: Mike Breed, Department of Ecology and Evolutionary Biology, University of Colorado Boulder Nestmate recognition and perceptual dimensions in honey bees Honey bees discriminate nestmates from non-nestmates using pheromonal signals. Bees must be able to generate enough unique signals to differentiate colonies within a population. In this talk I...

APPM Department Colloquium - John Boyd

Nov. 17, 2006

Event Description: John Boyd, Department of Atmospheric, Oceanic and Space Science, University of Michigan Exponentially accurate Rung-free approximation from samples on an evenly-spaced grid for non-periodic functions Approximating a function from its values at a f(xi) set of evenly spaced points xi through ( N +1)-point polynomial interpolation often fails...

APPM Department Colloquium - Richard Rotunno

Nov. 10, 2006

Event Description: Richard Rotunno, Earth and Sun Systems Laboratory, NCAR A generalization of Lorentz’s model for the predictability of flows with many scales of motion The idea that there is an inherent finite range of predictability for certain fluid flows originates with Lorenz (Tellus, 1969). This idea is based on...

APPM Department Colloquium - Greg Lyng

Nov. 3, 2006

Event Description: Greg Lyng, Department of Mathematics, University of Wyoming The secondary caustic in the semiclassical limit for the focusing nonlinear Schrödinger equation We consider the cubic focusing nonlinear Schrödinger equation in one space dimension, with fixed initial data, in the semiclassical limit when a dispersion parameter analogous to Planck’s...

APPM Department Colloquium - Jim Keener

Oct. 27, 2006

Event Description: Jim Keener, Distinguished Professor of Mathematics, Adjunct Professor of Bioengineering, University of Utah How cells make measurements A fundamental problem of cell biology is to understand how cells make measurements and then make behavior decisions in response to these measurements. The full answer to this question is not...

APPM Department Colloquium - Ying Lu

Oct. 20, 2006

Event Description: Ying Lu, Department of Sociology, University of Colorado Boulder Verbal autopsy methods with multiple causes of death Verbal autopsy procedures are widely used for estimating cause-specific mortality in areas without medical death certification. Data on symptoms reported by caregivers along with the cause of death are collected from...

APPM Department Colloquium - Congming Li

Oct. 13, 2006

Event Description: Congming Li, Department of Mathematics, University of Colorado Boulder Dynamic stability of the 3-D axi-symmetric Navier-Stokes equations with swirl I will present the joint work with Tom Hou on “Dynamic stability of the 3D axi-symmetric Navier-Stokes equations with swirl” and some related equations. I will briefly describe the...

APPM Department Colloquium - Michael Rempe

Oct. 6, 2006

Event Description: Michael Rempe, Applied Mathematics, Northwestern University Efficient computational strategies for simulating neural activity on branched structures Ever since Hodgkin and Huxley developed their foundational mathematical model of neuronal activity, the field of computational neuroscience has been growing rapidly. THis system of differential equations has been used to simulate...

APPM Department Colloquium - Roseanna Neupauer

Sept. 29, 2006

Event Description: Roseanna Neupauer, Department of Civil, Environmental, and Architectural Engineering, University of Colorado Boulder Wavelet analysis to characterize hydraulic properties of porous media Hydraulic properties of porous media, such as permeability and porosity, control subsurface flow and the movement of chemicals dissolved in groundwater. Typically, these properties are spatially...

APPM Department Colloquium - Anne Sheehan

Sept. 22, 2006

Event Description: Anne Sheehan, CIRES and Department of Geological Sciences, University of Colorado Boulder Seismic imaging of the earth’s crust and mantle Much like a medical CT scan, seismic waves can be used to make detailed images of the Earth’s interior. Most seismic processing involves time series analysis and enhancement...
