Stats, Optimization, and Machine Learning Seminar - Alec Dunton

Oct. 22, 2019

Alec Dunton, Department of Applied Mathematics, University of Colorado Boulder Learning a kernel matrix for nonlinear dimensionality reduction (Weinberger et. al. 2004) We investigate how to learn a kernel matrix for high dimensional data that lies on or near a low dimensional manifold. Noting that the kernel matrix implicitly maps...

Nonlinear Waves Seminar - S. Chakravarty

Oct. 22, 2019

S. Chakravarty, Department of Mathematics, University of Colorado Colorado Springs A class of rational solutions of the KPI equation I will revisit a class of KP "lump" solutions which were studied by Ablowitz & Villarroel as rational potentials of the non-stationary Schroedinger equation. Unlike other KPI lump solutions (simple lumps)...

Applied Math Colloquium - Manuchehr Aminian

Oct. 18, 2019

Manuchehr Aminian, Department of Mathematics, Colorado State University Using mathematical tools to understand the immune system How soon after exposure can we identify that you're infected with the flu? Can this be done prior to the onset of symptoms? Why do some animals tolerate bacterial infections better than others? It...

Math Bio Seminar - Lewis Baker

Oct. 15, 2019

Lewis Baker, Department of Applied Mathematics, University of Colorado Boulder Inference of Diffusion Coefficients from Single Particle Trajectories Membrane-targeting proteins are understood to diffuse on the surface of cells and occasionally associate with macromolecules integrated in the cell membrane. This association initiates reaction cascades within the cell, while introducing a...

Stats, Optimization, and Machine Learning Seminar - Purnendu

Oct. 15, 2019

Purnendu, ATLAS Institute, University of Colorado Boulder The mathematical secrets of Computational Origami Origami is the Japanese name for the centuries-old art of folding paper into representations of birds, insects, animals, plants, human figures, inanimate objects, and abstract shapes. In the purest form of origami, the figure is folded from...

Applied Math Colloquium - Steve Sain

Oct. 11, 2019

Steve Sain Jupiter Intelligence, Boulder CO Data Science @ Jupiter In 2017, the US faced over $300 billion in loses from hurricanes, severe weather, flooding, drought, fire, etc. These national catastrophes are placing an increasing burden on the public and are projected to worsen in the future. Jupiter Intelligence provides...

Computational Math Seminar - Xiangxiong Zhang

Oct. 10, 2019

Xiangxiong Zhang, Department of Mathematics, Purdue University Monotonicity in high order accurate schemes for diffusion operators with applications to compressible Navier-Stokes equations For gas dynamics equations such as compressible Euler and Navier-Stokes equations, preserving the positivity of density and pressure without losing conservation is crucial to stabilize the numerical computation...

Math Bio Seminar - Sabina Altus

Oct. 8, 2019

Sabina Altus, Department of Applied Mathematics, University of Colorado Boulder Multi-Structured Population Dynamics in Cyanobacteria Cyanobacteria are photosynthetic microorganisms with promising applications in renewable energy and agriculture as they are able to convert light energy into more stable forms of chemical energy, such as biomass, as well as kinetic energy...

Nonlinear Waves Seminar - Patrick Weidman

Oct. 8, 2019

Patrick Weidman Department of Mechanical Engineering, University of Colorado Boulder Steady flow of one uniformly rotating fluid layer above another immiscible uniformly rotating fluid layer. The steady laminar flow of two immiscible, uniformly rotating fluid layers is studied and exact similarity solutions of the axisymmetric Navier-Stokes equations in cylindrical polar...
