While global climate modeling algorithms are able to capture the mean behavior of the earth's climate system, sub-scale processes are usually unable to be resolved. In particular, Sea Surface Temperature (SST) anomalies can represent information that is not captured in model climatologies or reveal unaccounted changes in climate dynamics. Historically, these anomalies have been studied in a Linear Inverse Model (LIM) framework with some success in analyzing monthly, regional anomaly predictability. In this framework, parameters and uncertainties have typically been given point estimates.
The 20th Northwest Probability Seminar, a one-day mini-conference organized by the University of Washington, the Oregon State University, the University of British Columbia, the University of Oregon, and Microsoft Research, will be held on October 20, 2018. The conference will be hosted at Microsoft, supported by Microsoft Research and the Pacific Institute for the Mathematical Sciences (PIMS).
Locomotion and perception are a common thread between robotics and biology. Understanding these phenomena at a mechanical level involves nonlinear dynamics and the coordination of many degrees of freedom. In this talk, I will discuss geometric approaches to organizing this information in two problem domains: Undulatory locomotion of snakes and swimmers, and vibration propagation in spider webs.
We consider a certain two-parameter family of automorphisms of the affine plane over a complete, locally compact non-Archimedean field. Each of these automorphisms admits a chaotic attractor on which it is topologically conjugate to a full two-sided shift map, and the attractor supports a unit Borel measure which describes the distribution of the forward orbit of Haar-almost all points in the basin of attraction. We also compute the Hausdorff dimension of the attractor, which is non-integral.
Azhar Alhammali, Choah Shin, and Joe Umhoefer received travel support from SIAM to attend and present at the SIAM Geosciences conference to be held in March 2019 in Houston. Congratulations!
Tevian Dray is heading to Bénin to teach a 3-week course on differential geometry and general relativity. The invitation comes from the Institut de Mathématiques et de Sciences Physiques through the Volunteer Lecturer Program of the International Mathematical Union. He hasn't yet been told whether he will be teaching in English or French (or, more likely, both)...
