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.

"Davis Bottom: Rare History, Valuable Lives" reveals the fascinating history of a working-class neighborhood established in Lexington after the Civil War. Davis Bottom is one of about a dozen ethnic enclaves settled primarily by African-American families who migrated to Lexington from the 1860s to the 1890s in search of jobs, security and opportunity. 

The documentary is part of the Kentucky Archaeology and Heritage Series, produced by Voyageur Media Group, Inc. for the Kentucky Archaeological Survey and the Kentucky Heritage Council. The series is distributed by Kentucky Educational Television (KET) to viewers, teachers and students throughout the state. Wednesday's advance screening, part of the first-ever Kentucky Archaeology Month activities, is free and open to the public.

The UK Appalachian Center, Appalachian Studies, and the Graduate Appalachian Research Community (GARC) seek to promote interdisciplinary dialogue on issues in Appalachia. We are proud to follow up our first four successful symposia with the 2014 UK Appalachian Research Symposium and Arts Showcase.

Invisible War (2011), an Academy Award-nominated documentary, will be shown for free this Saturday morning, April 20, 2013,  at 10 AM at the Kentucky Theater.  This film documents the lives of women and men who have been sexually assaulted while serving in the U.S. military.  Several of the survivors have roots in Kentucky, and some of them will be at the screening to answer questions.  Come out, see the film, hear their stories.

Swati Chattopadhyay is an architect and architectural historian specializing in modern architecture and urbanism, and the cultural landscape of British colonialism. She is interested in the ties between colonialism and modernism, and in the spatial aspects of race, gender, and ethnicity in modern cities that are capable of enriching post-colonial and critical theory. She has served as a director of the Subaltern-Popular Workshop, a University of California Multi-campus Research Group, and is the current editor of the Journal of the Society of Architectural Historians (JSAH). She is the author of Representing Calcutta: Modernity, Nationalism, and the Colonial Uncanny (Routledge, 2005; paperback 2006), and Unlearning the City: Infrastructurein a New Optical Field (Minnesota, 2012 forthcoming). Her current work includes a new book project, "Nature's Infrastructure," dealing with  the infrastructural transformation of the Gangetic Plains between the 17th and 19th centuries.

Tom Conley is Lowell Professor in the Departments of Romance Languages and Visual and Environmental Studies at Harvard University. Conley studies relations of space and writing in literature, cartography, and cinema. His work moves to and from early modern France and issues in theory and interpretation in visual media. In 2003, Dr. Conley won a Guggenheim Fellowship for his work in topography and literature in Renaissance France.
