Event Description: Meredith Plumley, Department of Applied Mathematics, University of Colorado Boulder The effects of Ekman pumping on rotating Rayleigh-Bénard convection Rotating Rayleigh-Bénard convection is the canonical framework for investigating the fundamental dynamics of stars, planetary interiors, and terrestrial oceans. To understand these turbulent and rapidly rotating systems, several techniques...
Event Description: Paul Krause, Climate and Global Dynamics Laboratory , University Corporation for Atmospheric Research (UCAR) Influence sampling, strong predictability and analysis of non-observable trailing variables A novel sampling scheme for the state of an evolutive system of ordinary differential equations (o.d.e.), the Influence Sampling (IS) scheme, is presented for...
Event Description: Sebastián Ferrer Martinez , Departamento de Matematica Aplicada , University of Murcia , Spain On the N-Extended Euler System. Generalized Jacobi Elliptic Functions We study the integrable system ω i (υ)ʹ = α i ∏ ω j (υ), α 2 ∈ℝ, (1≤ i; j ≤ N) j≠i of...
Geophysical turbulence; beyond slow vortices and fast waves Peter Bartello Department of Atmospheric and Oceanic Sciences , McGill University Date and time: Thursday, December 10, 2015 - 2:00pm Location: ECCR 257 Abstract: A major achievement of mid-twentieth century meteorology and oceanography was to simplify the Navier-Stokes equations considerably (using two...
Rigorous Symbolic Dynamics and Entropy via Conley Index Theory Rafael Frongillo Department of Computer Science, University of Colorado Boulder Date and time: Thursday, November 19, 2015 - 2:00pm Location: ECCR 257 Abstract: Computers have helped us prove many theorems, which like the four-color theorem are mostly combinatorial or discrete in...
Hysteresis, reentrance, and glassy dynamics in systems of self-propelled rods Matthew Glaser Department of Physics , University of Colorado Boulder Date and time: Thursday, November 12, 2015 - 2:00pm Location: ECCR 257 Abstract: Non-equilibrium active matter made up of self-propelled particles with short-range repulsive interactions is a useful minimal system...
Impacts of Non-Divergence-Free Flows On The Coalescence of Initially Distant Buoyant Scalars on a Turbulent Free Surface Kenneth Pratt Department of Civil, Environmental, and Architectural Engineering , University of Colorado Boulder Date and time: Thursday, November 5, 2015 - 2:00pm Location: ECCR 257 Abstract: Lagrangian Coherent Structures (LCS) have been...
Computational Topology Techniques for Characterizing Time Series Data Liz Bradley Department of Computer Science , University of Colorado Boulder Date and time: Thursday, October 29, 2015 - 2:00pm Location: ECCR 257 Abstract: Full and accurate reconstruction of dynamics from time-series data - e.g., via delay-coordinate embedding - is a real...
