Particle filters for geophysical applications
30 Apr 2015  Presentations  Contributor(s): Mary Lou Zeeman
Avoiding degeneracy is a crucial challenge for particle filters. Results have shown that the number of particles scales exponentially with respect to the number of independent observations. In this talk I will review attempts to counteract this phenomenon by exploiting proposal densities. I will...

Realistic modeling and analysis of synchronization dynamics in powergrid networks
08 May 2015  Presentations  Contributor(s): Mary Lou Zeeman
An imperative condition for the functioning of a powergrid network is that its power generators remain synchronized. Disturbances can prompt desynchronization, which is a process that has been involved in large power outages. In this talk I will first give a comparative review of three leading...

Statistical Data Assimilation For Parameter Estimation In Costal Ocean Hydrodynamics Modeling
30 Apr 2015  Presentations  Contributor(s): Mary Lou Zeeman
Coastal ocean models are used for a variety of applications, including modeling tides and hurricane storm surge. These models numerically solve the shallow water equations, which are derived by depth integrating the NavierStokes equations. The inherent uncertainties in coastal ocean models are a...

Synchronization in power grid networks
07 May 2015  Presentations  Contributor(s): Laura Slivinski
This survey discusses Master Stability Function (MSF) analysis for determining stability of synchronization of coupled oscillators on network. In addition, we briefly discuss the derivation of the Swing equation that determine the dynamics of a node in power grid network, and...

Toward a hybrid particleensemble Kalman filter for assimilating data from Lagrangian instruments into high dimensional models
30 Apr 2015  Presentations  Contributor(s): Mary Lou Zeeman
Presented by Elaine Spiller on 32615Abstract:We discuss a recently proposed hybrid particleensemble Kalman filter for assimilating Lagrangian data, and apply it to a highdimensional quasigeostrophic ocean model. Effectively the hybrid filter applies a particle filter to the highly nonlinear,...

Vegetation patterns in mathematical models, and vegetation patterns in Horn of Africa
21 Apr 2016  Presentations
Visually striking largescale spatial patterns of vegetation have been observed in semiarid regions in the Americas, Africa and Australia. These have led to suggestions by theoretical ecologists that certain characteristics of the patterns may serve as earlywarning signs of desertification....

Where's the Math in Climate Science?
09 Nov 2015  Presentations  Contributor(s): Laura Slivinski
Abstract: Climate science is dominated by the use of largescale models, of which there are only 30 or so around the world. It might then seem that the need for mathematics is limited to areas that directly support the operation of such models. I will explain, by digging into the way the models...
