Polynomial Extension Operators. Part Iii, Leszek Demkowicz, Jay Gopalakrishnan, Joachim Schöberl Jan 2011

Polynomial Extension Operators. Part Iii, Leszek Demkowicz, Jay Gopalakrishnan, Joachim Schöberl

Mathematics and Statistics Faculty Publications and Presentations

In this concluding part of a series of papers on tetrahedral polynomial extension operators, the existence of a polynomial extension operator in the Sobolev space H(div) is proven constructively. Specifically, on any tetrahedron K, given a function w on the boundary ∂K that is a polynomial on each face, the extension operator applied to w gives a vector function whose components are polynomials of at most the same degree in the tetrahedron. The vector function is an extension in the sense that the trace of its normal component on the boundary ∂K coincides with w. Furthermore, the extension operator is …

Commuting Smoothed Projectors In Weighted Norms With An Application To Axisymmetric Maxwell Equations, Jay Gopalakrishnan, Minah Oh Jan 2011

Commuting Smoothed Projectors In Weighted Norms With An Application To Axisymmetric Maxwell Equations, Jay Gopalakrishnan, Minah Oh

Mathematics and Statistics Faculty Publications and Presentations

We construct finite element projectors that can be applied to functions with low regularity. These projectors are continuous in a weighted norm arising naturally when modeling devices with axial symmetry. They have important commuting diagram properties needed for finite element analysis. As an application, we use the projectors to prove quasioptimal convergence for the edge finite element approximation of the axisymmetric time-harmonic Maxwell equations on nonsmooth domains. Supplementary numerical investigations on convergence deterioration at high wavenumbers and near Maxwell eigenvalues and are also reported.

Symmetric Nonconforming Mixed Finite Elements For Linear Elasticity, Jay Gopalakrishnan, Johnny Guzmán Jan 2011

Symmetric Nonconforming Mixed Finite Elements For Linear Elasticity, Jay Gopalakrishnan, Johnny Guzmán

Mathematics and Statistics Faculty Publications and Presentations

We present a family of mixed methods for linear elasticity that yield exactly symmetric, but only weakly conforming, stress approximations. The method is presented in both two and three dimensions (on triangular and tetrahedral meshes). The method is efficiently implementable by hybridization. The degrees of freedom of the Lagrange multipliers, which approximate the displacements at the faces, solve a symmetric positive-definite system. The design and analysis of this method is motivated by a new set of unisolvent degrees of freedom for symmetric polynomial matrices. These new degrees of freedom are also used to give a new simple calculation of the …

Balance Systems And The Variational Bicomplex, Serge Preston Jan 2011

Balance Systems And The Variational Bicomplex, Serge Preston

Mathematics and Statistics Faculty Publications and Presentations

In this work we show that the systems of balance equations (balance systems) of continuum thermodynamics occupy a natural place in the variational bicomplex formalism. We apply the vertical homotopy decomposition to get a local splitting (in a convenient domain) of a general balance system as the sum of a Lagrangian part and a complemental "pure non-Lagrangian" balance system. In the case when derivatives of the dynamical fields do not enter the constitutive relations of the balance system, the "pure non-Lagrangian" systems coincide with the systems introduced by S. Godunov [Soviet Math. Dokl. 2 (1961), 947–948] and, later, asserted as …

The (Coming) Social Media Revolution In The Academy, Jessie Daniels, Joe R. Feagin Jan 2011

The (Coming) Social Media Revolution In The Academy, Jessie Daniels, Joe R. Feagin

Publications and Research

A revolution in academia is coming. New social media and other web technologies are transforming the way we, as academics, do our job. These technologies offer communication that is interactive, instantaneous, global, low-cost, and fully searchable, as well as platforms for connecting with other scholars everywhere.

Explicit Constructions Of Rip Matrices And Related Problems, Jean Bourgain, S J. Dilworth, Kevin Ford, Sergei Konyagin, Denka Kutzarova Jan 2011

Explicit Constructions Of Rip Matrices And Related Problems, Jean Bourgain, S J. Dilworth, Kevin Ford, Sergei Konyagin, Denka Kutzarova

Faculty Publications

We give a new explicit construction of n×N matrices satisfying the Restricted Isometry Property (RIP). Namely, for someε > 0, largeN, and any n satisfyingN1−ε ≤ n ≤ N, we construct RIP matrices of order k ≥ n1/2+ε and constant δ = n−ε. This overcomesthe natural barrier k = O(n1/2) for proofs based on small coherence, which areused in all previous explicit constructions of RIP matrices. Key ingredients in ourproof are new estimates for sumsets in product sets and for exponential sums with theproducts of sets possessing special additive structure. We also give a construction ofsets of n complex numbers whose …

Re-Locating Recycling: A Contextual Analysis Of Recycling Behavior In The Usa And Germany, Tsai-Shiou Hsieh Jan 2011

Re-Locating Recycling: A Contextual Analysis Of Recycling Behavior In The Usa And Germany, Tsai-Shiou Hsieh

Dissertations, Theses, and Capstone Projects

While recycling remains a common research topic within environmentally responsible behavior studies, it is little known how contextual factors such as physical environments, social interactions, and cultural backgrounds influence people's attitudes and behavior. This research adopts an ecological framework and conducts a mixed-method qualitative inquiry of whether and how relocation has impacts on people's ecological thinking and behavior in their everyday life. Semi-structured interviews were conducted within two groups of people: Americans who moved to Munich and Germans who moved to New York City. Interviews were conducted in participants' homes or workplaces. Pictures were taken inside the apartments, in common …

Getting Into Character: Cultivating Identities In A Teen-Theatre Peer-Education Program, Valerie A. Futch Jan 2011

Getting Into Character: Cultivating Identities In A Teen-Theatre Peer-Education Program, Valerie A. Futch

Dissertations, Theses, and Capstone Projects

This study investigated the role of community theatre participation on adolescent and young adult identity development. The theatre program, known as The SOURCE, focuses on sex-education through a peer-education model. The experiences of young adults, who are now aged 18-34, were examined through interviews (N=20), identity maps (N=9), and a survey (N=64) in order to understand how participation in this group influenced their development. While much of the literature documents the successes of such programs while youth participate, few document the longer-term impacts of such participation (Saldaña, McCammon, Omasta, & Hines, 2011). Data reveal how such involvement informed the youths' …

The United States Of The World: Human Rights, Political Entrepreneurship, And U.S. Foreign Policy Via Affective And Rational Politics, Marriah Star Jan 2011

The United States Of The World: Human Rights, Political Entrepreneurship, And U.S. Foreign Policy Via Affective And Rational Politics, Marriah Star

Dissertations, Theses, and Capstone Projects

This study examines how Political Entrepreneurs in the United States Congress responded to human rights abuses in six countries during the 1970s and 1980s: Cambodia, El Salvador, South Africa, the Soviet Union, Taiwan, and Uganda. It presents a four-point model for approaching the study of United States human rights policy. The key element in all the cases is bonding social capital, also called affective politics. American policy towards the Soviet Union and Uganda both demonstrate the integration of international, transnational, and domestic politics. Taiwan receives special attention because U.S. Taiwan policy continues to exemplify the integration of international relations, transnational …

Trait Anxiety And Trait Disgust In Spider Phobia, Laura Vernon, Michiyo Hirai Jan 2011

Trait Anxiety And Trait Disgust In Spider Phobia, Laura Vernon, Michiyo Hirai

Psychological Science Faculty Publications

There is evidence for the role of trait anxiety in the specific phobias, and spider phobia in particular. Recently, trait disgust has received attention in relation to specific phobia and researchers and theorists have begun to address its contributions to phobia etiology, maintenance, and treatment processes. There is now strong evidence that a trait or dispositional proneness to experience disgust is related to spider phobia. What is perhaps more important is emerging evidence that both trait anxiety and trait disgust may contribute to spider phobia severity independently of one another. However, the overall picture is far from clear and distinguishing …
