Event Description: Michael Wakin , Department of Electrical Engineering and Computer Science , Colorado School of Mines Slepian Sequences and Subspace Models for Signal Processing Low-dimensional subspace models offer a convenient representation for many high-dimensional signals; such models form the backbone of least-squares signal processing and many common compression techniques...

Joel Zylberberg, Department of Physiology and Biophysics, University of Colorado School of Medicine Mathematical and Computational Principles Underlying Robust Perception and Memory The nervous system is a surprisingly noisy place. For example, if one presents the exact same stimulus to an animal many times, and records the activities of their...

Time: Friday, December 11, 2015 - 4:00pm Location: ECCR 150 Topology of configuration spaces of hard spheres Joint Talk with Department of Mathematics Matthew Kahle Department of Mathematics , Ohio State University Abstract: Hard spheres are routinely studied as model particles in statistical mechanics. However, the underlying phase space or...

Paul Constantine Department of Applied Mathematics and Statistics , Colorado School of Mines Date and time: Friday, December 4, 2015 - 3:00pm Location: ECCR 245 Abstract: Scientists and engineers use computer simulations to study...

Chain reactions Tadashi Tokieda Poincaré Distinguished Visiting Professor, Stanford University Date and time: Friday, November 6, 2015 - 3:00pm Location: ECCR 245 Abstract: To every action, there is an equal and opposite reaction. However, there turn out to exist in nature situations where the reaction seems to be neither equal...

Blowup Criteria for 3D Navier-Stokes Equation: the Vector Potential as a Possible Blowup Criterion Koji Ohkitani School of Mathematics and Statistics , University of Sheffield Date and time: Friday, October 30, 2015 - 3:00pm Location: ECCR 245 Abstract: We consider basic regularity issues of the Navier-Stokes equations, which is potentially...

Requiem for Moore's Law Vladimir Rokhlin Department of Computer Sciences , Yale University Date and time: Friday, October 9, 2015 - 3:00pm Location: ECCR 245 Abstract: Moore's law states that every 18 months, the speed and memory of one's computer are doubled, assuming constant price. This observation was made in...

Computational and Mathematical Challenges in Numerical Weather Prediction Yuanfu Xie Earth Systems Research Laboratory , National Oceanic and Atmospheric Administration Date and time: Friday, October 2, 2015 - 3:00pm Location: ECCR 245 Abstract: Numerical weather prediction is not only scientific research but has strong socio impact, such as predictions of...
