# Events for 09/26/2019 from all calendars

## Student/Postdoc Working Geometry Seminar

**Time:** 3:00PM - 4:00PM

**Location:** BLOC 628

**Speaker:** A. Harper, TAMU

**Title:** *Mukai 6.2 cont'd*

## Maxson Lecture Series

**Time:** 4:00PM - 5:00PM

**Location:** BLOC 117

**Speaker:** David A. Cox, Amherst College

**Title:** *Maxson Lecture #2: Geometric Modeling, Rees Algebras, and Rational Normal Scrolls*

**Abstract:** In the first part of the lecture, I will consider a parametrized quartic curve in the projective plane from three perspectives: • Geometric modeling, where we find the implicit equation using moving curves. • The Rees algebra, where we consider its defining equations. • Curves on rational normal scrolls, where we get insight into the Rees algebra. The goal is to link the algebra and geometry. The second part of the lecture will focus on the role of singularities and end with an unsolved problem about sextic plane curves with 10 double points. This is join work with Teresa Cortadellas and Carlos D’Andrea of the University of Barcelona.

## Industrial and Applied Math

**Time:** 5:15PM - 6:15PM

**Location:** Bloc 220

**Speaker:** Weston Baines, Texas A&M

**Title:** *Filtering Shot Noise in Lidar Data*

**Abstract:** Light Detection and Ranging (Lidar) is a remote sensing method used to produce 3D terrain maps. Lidar scans are expensive and time consuming, sometimes requiring several passes of a scene to obtain acceptable data fidelity. For a low number of scene passes lidar data is primarily corrupted by shot noise. It is desirable to filter the shot noise to increase data efficiency. In this talk I will discuss the basic operation of lidar systems and the work I did at the Geospatial Research Laboratory this past summer in removing shot noise from Lidar data.
