Applied Math Seminar – Wei Zhu, University of Alabama

228 Gordon Palmer Hall Tuscaloosa, AL, United States

Title: New augmented Lagrangian method for a curvature dependent segmentation model Abstract: Augmented Lagrangian methods (ALMs) have proved to be successful for the minimization of curvature dependent functionals in image processing. However, those ALM based algorithms often suffer from choosing appropriate penalty parameters in the numerical implementation. In this talk, we will discuss our recent

Applied Math Seminar – Aijun Song, UA Dept. of Electrical and Computer Engineering

228 Gordon Palmer Hall Tuscaloosa, AL, United States

Title: Time reversal acoustic communication in the ocean Abstract: The global marine ecosystem is undergoing significant changes due to human activities and natural processes. These changes call for enhanced capabilities to sample and communicate in the oceans. With this background, underwater acoustic communication has attracted much attention across multiple disciplines, as this key subsea technology

Applied Math Seminar – Lin Mu, Oak Ridge National Laboratory

228 Gordon Palmer Hall Tuscaloosa, AL, United States

Title: A Priori and a posteriori error estimate for weak Galerkin finite element method on polygonal meshes Abstract:  Polygonal mesh has advantages including lower DOFs requirement for the same level of accuracy and more flexibility in generating mesh, and better mesh quality over standard discretization with quad mesh or triangular mesh. Also the hanging nodes

Applied Math Seminar – Kevin Curtin, UA Department of Geography

228 Gordon Palmer Hall Tuscaloosa, AL, United States

Title: Determining Optimal Police Patrol Areas…and More: a Research Program in Quantitative Human Geography Abstract:  My research program is rooted in the Quantitative Revolution in Geography that began in the 1950s, and that has culminated in the broad acceptance and use of Geographic Information Systems. More specifically, my research lies in the use of quantitative methods

Applied Math Seminar – Kyle Mandli (Columbia University)

Title of talk:  Computational Challenges to Prediction and Mitigation of Coastal Hazards Abstract: Coastal flooding due to severe storms is one of the most widespread and damaging hazards faced around the world.  The threat of these events has grown not only due to increased population and economic reliance on coastal regions but also due to

Applied Math Seminar – Vishesh Vikas (University of Alabama)

228 Gordon Palmer Hall Tuscaloosa, AL, United States

Title: Applied Mathematics for Soft Robotics Abstract: Soft materials are a bulk or composite collection of matter that undergoes deformations of similar or greater magnitude than the deformation of the environment, either plastically or elastically, within the force regime applied by its environment. For roboticists, soft materials can withstand impacts, are elastic and highly deformable,

Colloquium – Maria Laura delle Monache (Inria Grenoble – Rhône Alpes)

346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United States

Topic:  Control of traffic flow: from ramp metering to autonomous vehicles Abstract: In this talk, we will consider different control frameworks for traffic flow. In particular, we will show the evolution of traffic control from classical strategies (for example ramp-metering) to more modern approaches using autonomous vehicles. We will introduce different ways to describe mathematically
