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.

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.

TITLE: Square roots of divergence form operators on L^p spaces

ABSTRACT: An abstract is available online at

http://www.ms.uky.edu/~kott/PDEseminarf13/Haller-Dintelmann.pdf

The University of Kentucky Political Ecology Working Group is hosting the third annual Dimensions of Political Ecology: Conference on Nature Society.

Now in its third year, the 2013 Dimensions of Political Ecology Conference will provide opportunities to engage with contemporary scholarship on the political-economic causes and effects of environmental degradation and ecological change. With an interdisciplinary and international group of presenters, panelists, and keynote speakers, this year's conference will offer considerable insight into pressing contemporary questions relating to sustainability, global climate change, and local environmental conflicts. This year, we have over 200 scheduled presenters, representing a wide variety of geographic and disciplinary affiliations.

The final program can be view here.

 

Listen to a podcast about the Political Ecology Group below.

The dates for the event are 2/28 (5:30 PM) until 3/2 (10:00 PM).

The final program link is here.

The conference website can be found here.

And we also have a podcast.

Networked Humanities: From Within and Without the University

A Digital Humanities Symposium

February 15-16, 2013

The University of Kentucky

Writing, Rhetoric, and Digital Media Program

Keynote Speakers:

Kathleen Stewart, Professor of Anthropology, University of Texas

Malcolm McCullough, Professor of Architecture, University of Michigan

Of all the topics of interest to the digital humanities, the network has received little attention among digital humanities proponents.  Yet, we live in a networked society: texts, sound, ideas, people, movements, consumerism, protest movements, politics, entertainment, academia, and other items circulate in networks that come together and break apart at various moments. While there exist networked spaces of interaction for digital humanities work – such as HASTAC or specific university centers -  we still must consider how networks affect traditional and future goals of humanities work. Have the humanities sufficiently addressed the ways their work, as networks, affect other networks, within and outside of the humanities? What might be a networked digital humanities or what is it currently if it does, indeed, exist? Can an understanding of the humanities as a series of networks affect – positively or negatively - the ways the public perceive its research, pedagogy, and mission?

The University of Kentucky’s Writing, Rhetoric, and Digital Media Program invites proposals for a two day symposium devoted to discussion of the implications of a networked digital humanities. The symposium will bring together academic and professional audiences in order to rethink the taxonomy of humanities so that we emerge with a network of people and ideas beyond the traditional taxonomy of “humanities” work. Thus, talks will not be limited to traditional humanities areas of study. 

Possible topics might include (but are not limited to):

·      Public humanities work

·      Networks among disciplines

·      Ecologies

·      Animal and human networks

·      Online spaces

·      Mapping/Geography

·      Economics and the humanities

·      Labor and the humanities

·      Digital production of texts

·      Community work

·      Workplace organization

·      The university as network

·      Archives and Obsolescence

February 15-16, 2013

Panels, roundtables, performative pieces, and alternative forms of delivery are welcome and encouraged.

No registration fee to attend or present. Please send 250 word proposals to  Jeff Rice j.rice@uky.edu  by September 1, 2012.
