Event Description: Nicholas Featherstone, Department of Applied Mathematics, University of Colorado Boulder Rise to the Sun: A Modeler's Perspective on the Solar Dynamo Problem The Sun reverses its large-scale magnetic polarity once every roughly eleven years through a process known as the solar dynamo. Understanding the source of this dynamo...
Event Description: Aaron Clauset, Department of Computer Science, University of Colorado Boulder Safe Leads and Lead Changes in Competitive Team Sports In this talk, we will investigate the time evolution of lead changes within individual games of competitive team sports. Exploiting ideas from the theory of random walks, we first...
Event Description: Daniel J Scheeres, Department of Aerospace Engineering Sciences, University of Colorado Boulder New relative equilibria and their implications in the Full 3-Body Problem In the gravitational 3-body problem, if the bodies are assumed to be rigid, spherical and of finite density, there are 28 distinct relative equilibria which...
Thursday, April 28, 2016 2:00 PM - 3:00 PM Main Campus - Engineering Office Tower - 226: Applied Math Conference Room Hui-Shun Kuan, Department of Physics, University of Colorado Boudler Nonlinear dynamics and phase space flows to understand molecular motor motion on antiparallel lanes Motor protein motion on biopolymers can...
Event Description: Behrouz Touri; Department of Electrical, Computer, and Energy Engineering; University of Colorado Boulder Distributed Convex and Nonconvex Optimization Over Time-varying Networks In this talk, we discuss distributed optimization over time-varying networks. We revisit some of the recently developed distributed optimization techniques including averaging-based methods, saddle-point-based dynamics, and push-sum-based...
Event Description: Carrie Morrill , National Oceanic and Atmospheric Association (NOAA), Boulder, CO Climate surprises in the paleoclimate record Paleoclimate archives such as ice cores and ocean sediments contain numerous examples of complex and non-linear behaviors of the climate system. Feedback and threshold processes in the coupled atmosphere-ocean-sea ice system...
Event Description: Hector Lomelí, Department of Mathematics , University of Texas at Austin ON HAMILTONIAN FLOWS WHOSE ORBITS ARE STRAIGHT LINES We say that a Hamiltonian $H$ is affine-integrable if its flow is linear in time. Trivial examples are Hamiltonians $H(q; p)$ that do not depend on the coordinate $q$...
Event Description: Andrew Jackson , Department of Earth Sciences , ETH Zürich Numerical models of the Earth's magnetic field: From conventional to magnetostrophic The last 25 years has seen great progress in 3D self-consistent numerical models of the geodynamo. In particular, thermal driving is able to create fluid motion that...
Event Description: Juan Restrepo , Department of Applied Mathematics, University of Colorado Boulder Synchronization of interacting quantum dipoles Arrays of synchronized oscillators are ubiquitous in biological, physical and engineering systems. Although there has been significant progress in the study of synchronization in classical systems, the understanding of the same phenomenon...
