We address the long-time behavior of a non-rotational von Karman plate in an inviscid potential flow. The model arises in aeroelasticity and models the interaction between a thin, nonlinear panel and a flow of gas in which it is immersed [6, 21, 23]. Recent results in [16, 18] show that...
We analyze the well-posedness of a flow-plate interaction considered in [22, 24]. Specifically, we consider the
Kutta-Joukowski boundary conditions for the flow [20, 28, 26], which
ultimately give rise to a hyperbolic equation in the half-space (for the flow) with mixed
boundary conditions. This boundary condition has been considered previously...
We consider the well-posedness of a model for a flow-structure interaction. This model describes the dynamics of an elastic flexible plate with clamped boundary conditions immersed in a supersonic flow. A perturbed wave equation describes the flow potential. The plateʼs out-of-plane displacement can be modeled by various nonlinear plate equations...
We consider flow-structure interactions modeled by a modified wave equation coupled at an interface with equations of nonlinear elasticity. Both subsonic and supersonic flow velocities are treated with Neumann type flow conditions, and a novel treatment of the so called Kutta-Joukowsky flow conditions are given in the subsonic case. The...
In Fall 2006, a faculty member in George Washington University's University Writing 20 (UW20) program began incorporating service learning into her theme-based first-year writing course. Along with her librarian partner, they linked two research assignments to the service work of the students. An end-of-semester survey was administrated over three semesters...
This article describes a grant-funded project with the final goal of creating information literacy collaborative partnerships among academic, school, and public libraries. The objectives of the grant as well as an overall description of the project are stated. The emphasis of the article is on the process followed to create...
Assessing students' information literacy skills can be difficult depending on the involvement of the librarian in a course. To overcome this, librarians created an assignment called the Paper Trail, where students wrote a short essay about their research process and reflected on what they would do differently. Through reviewing and...
Self-harm, which consists of non-suicidal self-injury and attempted suicide, is a public health problem that is not well understood. There is conflicting evidence on the role of gender in predicting self-harm. Abuse history also is a potentially relevant factor to explore, as it is related to both gender and self-harm....
OBJECTIVES: To improve understanding of factors that may influence disclosure of complementary and alternative medicine (CAM) use in the U.S.
DESIGN: Cross-sectional survey.
METHODS: Data are from the 2001 Health Care Quality Survey (HCQS), a nationally representative study of adults aged 18 and older living in the continental United States....
In this paper dynamic von Karman equations with localized interior damping supported in a boundary collar are considered. Hadamard well-posedness for von Karman plates with various types of nonlinear damping are well known, and the long-time behavior of nonlinear plates has been a topic of recent interest. Since the von...
