Feb. 3, 2011

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...

Dynamical Systems Seminar: Yuzuru Sato

Jan. 20, 2011

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...

Computational Math Seminar: Hari Rajaram

Jan. 18, 2011

Overview of Ice Sheet and Glacier Flow and Modeling Hari Rajaram Department of Civil, Environmental, and Architectural Engineering, CU Boulder Date and time: Tuesday, January 18, 2011 - 3:45pm Abstract: In this talk, I will present the basic equations for ice sheet and glacier modeling. Typically, the three equations are...

Colloquium: Bengt Fornberg

Jan. 15, 2010

Radial Basis Function Methods for Solving Partial Differential Equations Bengt Fornberg Applied Mathematics , University of Colorado Boulder Date and time: Friday, January 15, 2010 - 4:30pm Abstract: For the task of solving PDEs, finite difference (FD) methods are particularly easy to implement. Finite element methods are more flexible geometrically,...

APPM Department Colloquium - Elizabeth Bradley

Nov. 16, 2007

Event Description: Elizabeth Bradley, Department of Applied Mathematics, University of Colorado Boulder Dynamics of data assimilation Numerical solvers cannot track unmodelled effects like noise, and this becomes a particularly serious issue in complex nonlinear systems like fluid flows. One way to address this problem is to use observations of the...

APPM Dynamics Seminar - Colleen Webb

Nov. 15, 2007

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...

Computational Math Seminar - Chris Woods

Nov. 13, 2007

Event Description: Chris Woods, Department of Applied Mathematics, University of Colorado Boulder Exploration of mechanistic changes in vascular structure associated with pulmanary hypertension modeled with CFD Physiological simulation of cardiovascular flow is highly dependent on proper implementation of boundary conditions. Recognition of patient specific pulmonary vascular structure and patient specific...

APPM Department Colloquium - François G Meyer

Nov. 9, 2007

Event Description: François G Meyer, Department of Electrical and Computer Engineering, University of Colorado Boulder We can read your mind: the decoding of fMRI datasets Very recently, functional Magnetic Resonance Imaging (fMRI) has been used to infer subjective experience and brain states of subjects immersed in natural environments. These environments...

APPM Department Colloquium - Mike Wakin

Nov. 2, 2007

Event Description: Mike Wakin, Assistant Professor, University Michigan The Geometry of Compressed Sensing Compressed Sensing (CS) is a rapidly emerging field based on the revelation that signals obeying sparse models can be recovered from small numbers of nonadaptive (even random) linear measurements. In this talk I will survey some of...

APPM Dynamics Seminar - Benjamin Jamroz

Nov. 1, 2007

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...
