    Annotated Bibliography by Daniel Koll

  2. 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...

  3. Realistic modeling and analysis of synchronization dynamics in power-grid networks

    08 May 2015 | Presentations | Contributor(s): Mary Lou Zeeman

    An imperative condition for the functioning of a power-grid 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...

  4. Sea Ice Physics and Biology

    18 Mar 2015 | Educational Materials

    Bibliography by S.F.Ackley to accompany tutorial lecture on Biology/Physics Interface in Sea Ice at the 2011 MBI Workshop on Ocean Ecologies and their Physical Habitats in a Changing Climate

  5. 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 Navier-Stokes equations. The inherent uncertainties in coastal ocean models are a...

  6. 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...

  9. Toward a hybrid particle-ensemble 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 3-26-15Abstract:We discuss a recently proposed hybrid particle-ensemble Kalman filter for assimilating Lagrangian data, and apply it to a high-dimensional quasi-geostrophic ocean model. Effectively the hybrid filter applies a particle filter to the highly nonlinear,...

  10. Vegetation patterns in mathematical models, and vegetation patterns in Horn of Africa

    21 Apr 2016 | Presentations

    Visually striking large-scale spatial patterns of vegetation have been observed in semi-arid regions in the Americas, Africa and Australia. These have led to suggestions by theoretical ecologists that certain characteristics of the patterns may serve as early-warning signs of desertification....

  11. Where's the Math in Climate Science?

    09 Nov 2015 | Presentations | Contributor(s): Laura Slivinski

    Abstract: Climate science is dominated by the use of large-scale 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...
