Abstract LiDAR point clouds contain measurements of complicated natural scenes and can be used to update digital elevation models, glacial monitoring, detecting faults and measuring uplift detecting, forest inventory, detect shoreline and beach volume changes, landslide risk analysis, habitat mapping, and urban development, among others. A very important application is the classification of the 3D cloud into elementary classes. For example, it can be used to differentiate between vegetation, man-made structures, and water.
The past two decades has witnessed a dramatic burst of applications of topological thinking and theorems in the applied sciences, ranging from statistics to sensor networks, neuroscience, and more, to be surveyed here. Several challenges remain, including: (1) how to compute topological quantities efficiently; (2) how to extend the set of current applications and methods; and, perhaps most importantly, (3) how to educate end-users in the meaning and proper use of homological tools.This talk will demonstrate why homology is one of the most exciting new tools in applied mathematics.
Estimation of ground-level geoelectric fields has been identified by the electrical power industry as a key
capability in assessment and mitigation of the impacts of space weather on electrical power infrastructure. In
response to this societal need, an operational system to produce locally relevant geoelectric fields is being
developed by the NOAA's Space Weather Prediction Center and the USGS Geomagnetism Program. The first version of
the NOAA-USGS Geoelectric Field Maps data product became operational in Fall 2020, and an improved version is in
A new faculty learning community that focuses on antiracist teaching practices is being planned for Spring 2021. Organized by Raven Chakerian, Filix Maisch, Shawn Massoni, Dan Rockwell, Rachael Cate, and Liddy Deter, this new community of practice (COP) will create a safe space where instructors and GTAs will have agency and feel empowered to explore antiracism in a community of peers of similar ranking. The COP is co-sponsored by the Office of Faculty Affairs and the Center for Teaching and Learning. More details, including how to participate, will follow soon....
