APPM+CS Postdoc Seminar - Jeffrey Hokanson

Dec. 14, 2018

In many applications throughout science and engineering, model reduction plays an important role replacing expensive large-scale linear dynamical systems by inexpensive reduced order models that capture key features of the original, full order model. One approach to model reduction is to find reduced order models that are locally optimal approximations...

Spatiotemporal Dynamics of Neocortical Seizure Activity Seizures are defined as sudden, abnormal electrical disturbances in the brain. Patients diagnosed with epilepsy have chronic, recurrent seizures and often require clinical intervention to prevent these episodes. Unfortunately, a large portion of epilepsy patients do not respond to current treatment options, in part...

Robert W Easton - Spacecraft Mission Design

June 5, 2018

Spacecraft Mission Design Newton’s laws are used to design spacecraft missions to explore our solar system. Onboard controls are used to change the velocity and orientation of a spacecraft. Mission design must combine dynamics, control theory, and computation. When Newton’s equations of motion are formulated as a Hamiltonian system, the...

Beyond sparsity: compressed sensing with deep generative priors Over the last several decades, sparsity and compressed sensing has been a dominant theme in signal recovery, leading to significant improvements in MRI imaging and new algorithms in a wide range of fields. We'll begin by seeing some exciting recent algorithms for...

Data Science Meets Geometry Every minute, the humankind produces about 2000 Terabytes of data and learning from this data has the potential to improve many aspects of our lives. Doing so requires exploiting the geometric structure hidden within the data. Our overview of different models in data and computational sciences...

APPM Graduate Recruitment - Keith Julien

March 10, 2017

Event Description: Keith Julien, Department of Applied Mathematics, University of Colorado Boulder Asymptotic strategies for modeling geophysical and astrophysical flows Geophysical and astrophysical fluid flows occur on scales that are often strongly influenced by forces such as buoyancy, rotation, magnetic and shear. In many cases it is typical that one...

APPM Graduate Recruitment - Ian Grooms

March 3, 2017

Event Description: Ian Grooms, Department of Applied Mathematics, University of Colorado Boulder Multiscale Methods in Ocean Modeling Equations describing the motions of the ocean are reasonably well known, but numerical ocean models are unable to resolve all length scales. Rather than view numerical ocean models as hopelessly inaccurate approximations to...

Special Seminar

Feb. 7, 2017

Event Description: Daniel Appelö, Department of Applied Mathematics, University of New Mexico High order accurate methods for time dependent problems The defining feature of waves is their ability to carry information over long distances relative to their wavelength. This intrinsic feature is what makes high order accurate methods errors so...

Special Seminar

Feb. 2, 2017

Event Description: James Brannick, Department of Mathematics, Penn State University Algebraic Multigrid: Theory and Practice This talk gives an overview of recent progress made in the design and analysis of algebraic multigrid methods. The focus is on the setup algorithm that automatically constructs the multilevel hierarchy used in the solve...
