The National Conference on Undergraduate Research will bring nearly 4,000 additional students from across the country to the UK campus where they will present their research and creative endeavors while meeting other like-minded students.
Title: On a thermodynamically consisted Stefan problem with variable surface energy
Abstract: Given a filtration of a simplicial complex we can construct a series of invariants called the persistent homology groups of the filtration. In this talk we will give a basic introduction to the theory of persistence and explain how these ideas can be used in data analysis.
Title: Universal wave patterns
Abstract: A feature of solutions of a (generally nonlinear) field
theory can be called "universal" if it is independent of side conditions like initial data. I will explain this phenomenon in some detail and then illustrate it in the context of the sine-Gordon equation, a fundamental relativistic nonlinear wave equation. In particular I will describe some recent results (joint work with R. Buckingham) concerning a universal wave pattern that appears for all initial data that crosses the separatrix in the phase portrait of the simple pendulum. The pattern is fantastically complex and beautiful to look at but not hard to describe in terms of elementary solutions of the sine-Gordon equation and the collection of rational solutions of the famous inhomogeneous Painlev\'e-II equation.
Proto-Indo-European, which Dr Byrd studies, is the prehistoric ancestor of hundreds of languages, including English, Spanish, Greek, Farsi, Armenian, and more.
Title: Automating and Stabilizing the Discrete Empirical Interpolation Method for Nonlinear Model Reduction
Abstract: The Discrete Empirical Interpolation Method (DEIM) is a technique for model reduction of nonlinear dynamical systems. It is based upon a modification to proper orthogonal decomposition which is designed to reduce the computational complexity for evaluating reduced order nonlinear terms. The DEIM approach is based upon an interpolatory projection and only requires evaluation of a few selected components of the original nonlinear term. Thus, implementation of the reduced order nonlinear term requires a new code to be derived from the original code for evaluating the nonlinearity. I will describe a methodology for automatically deriving a code for the reduced order nonlinearity directly from the original nonlinear code. Although DEIM has been effective on some very difficult problems, it can under certain conditions introduce instabilities in the reduced model. I will present a problem that has proved helpful in developing a method for stabilizing DEIM reduced models.
Public lecture by Dr. Benor is Associate Professor of Contemporary Jewish Studies at Hebrew Union College – Jewish Institute of Religion (Los Angeles). Her book, Becoming Frum: How Newcomers Learn the Language and Culture of Orthodox Judaism, was published in 2012.
Just recently, the Linguistics Program's Andrew Byrd was interviewed by the BBC's Newsday radio series. The interview served to highlight Byrd's work studying the "Proto-Indo-European" language which dates back thousands of years. In the interview, Byrd gives listeners a glimpse of the language's history and a chance to hear the language given breath.
Emancipation, New Sensibility, and the Challenge of a New Era: Theory, Practice, and Pedagogy.
Sessions all day Thursday, Friday & Saturday in the UK Student Center with scholars and students from around the world.
It was an excellent summer for the Department of English as six faculty members published books in highly-regarded presses.
