Crit Callebs (Eastern Band Cherokee descendant) is a traditional hunter, food gatherer, and fire-tender and lives on the Yakama Nation Indian Reservation. He is completing his Master’s Degree at Central Washington University (CWU) in Cultural Resource Management with an expertise in treaty rights concerning Indian hunting and fishing. He served as the Native American Liaison at the Center for Diversity and Social Justice and was a very popular guest lecturer for the American Indian Studies program. Crit is a trainer for the “Since Time Immemorial” tribal sovereignty and history curriculum implemented in K-12 classrooms in Washington State. As an active member of the Northwest Indian Storytelling Association he has been a featured storyteller for the Tseil-Waututh Nation, CWU Museum of Culture and Environment, Colville Tribes Youth “Warrior Camp” and is the 2014 Alaska Spirit of Reading storyteller. Crit is also a professional survival trainer and former instructor for the world renowned Boulder Outdoors Survival School. One of his great passions is teaching youth and adults how to be self-reliant in the wilderness. Using his gift of storytelling, he travels throughout the U.S. and Canada sharing traditional stories, teaching cultural camps and conducting workshops that promote self-awareness, ancestral skills, and Indigenous values.
The National Conference on Undergraduate Research is an annual student conference dedicated to promoting undergraduate research, scholarship, and creative activity in all fields of study. Unlike meetings of academic professional organizations, this gathering of young scholars welcomes presenters from institutions of higher learning from all corners of the academic curriculum. This annual conference creates a unique environment for the celebration and promotion of undergraduate student achievement, provides models of exemplary research and scholarship, and helps to improve the state of undergraduate education.
Title: On the ground state of the magnetic Laplacian in corner domains
Abstract: I will present recent results about the first eigenvalue of the magnetic Laplacian in general 3D-corner domains with Neumann boundary condition in the semi-classical limit. The use of singular chains show that the asymptotics of the first eigenvalue is governed by a hierarchy of model problems on the tangent cones of the domain. We provide estimations of the remainder depending on the geometry and the variations of the magnetic field. This is a joint work with V. Bonnaillie-Nol and M. Dauge.
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.
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.
