Brown Bag Seminar
The brown bag seminar is a weekly meeting organized by and for graduate students. The goal of the brown bag is to encourage students to practice presenting their work by giving talks to each other in a casual setting.
Space-Periodic Behavior of Laminar Flames near the Extinction point
DateFriday, November 2, 2018 - 12:00pm
AbstractIn this talk, I summarize a proof claiming that the asymptotic behavior of the free boundary of a laminar flame converges to a sphere near its extinction point. This is a two-part problem: we seek to identify the initial conditions that make the above statement true. This problem is motivated by the Stefan Problem which takes form of a Free Boundary Value Problem. We will discuss what the Stefan Problem is, state the Free BVP, describe the initial condition of the flame in detail and outline a constructive geometric proof of the movement of the boundary of the laminar flame in space time as the flame extinguishes.
Computational Hyperspectral Imaging: Math, Methods, and Mayhem
DateFriday, November 16, 2018 - 12:00pm
AbstractHyperspectral imaging has many applications, including food quality and safety, cancer screening, crop assessments in agriculture, and fake currency detection, though hyperspectral imaging systems can be excessively complex and expensive. To simplify these optical systems, computational methods are used to calculate hyperspectral data from specially encoded optical signals. We will break down the mathematical structuring of a patented optical encoding system, explore some deconvolution methods to calculate hyperspectral information from encoded signals, and discuss the implications of different real-world training data sets.
