Numerical Integration Of Linear And Nonlinear Wave Equations, Laura Lynch Dec 2004

Numerical Integration Of Linear And Nonlinear Wave Equations, Laura Lynch

Dissertations, Theses, and Student Research Papers in Mathematics

We begin our study with an analysis of various numerical methods and boundary conditions on the well-known and well-studied advection and wave equations, in particular we look at the FTCS, Lax, Lax-Wendroff, Leapfrog, and Iterated Crank Nicholson methods with periodic, outgoing, and Dirichlet boundary conditions. We will then extend our study to the nonlinear equation gtt = gxx – gt2/g, introduced by Khoklov and Novikov. The nonlinearities are similar to those seen in General Relativity, and thus our analysis establishes the effects of numerical integration and boundary condition choices on the long-term stability of gravitational wave simulations.

Stressing Concepts And Teaching In The Classroom: A Low-Technology Approach Using Concept Tests And Classroom Polls, Walter S. Borowski Nov 2004

Stressing Concepts And Teaching In The Classroom: A Low-Technology Approach Using Concept Tests And Classroom Polls, Walter S. Borowski

EKU Faculty and Staff Scholarship

Electronic student response technologies can be used effectively to increase learning in the classroom. Although these systems are not terribly expensive, their purchase may be out of reach for many departments and institutions. Here we model a low-technology approach that stresses active learning, peer teaching, and testing student understanding of key concepts by using think-pair-share sessions and in-class responses to key concept-test questions.

Questions used in class are chosen carefully to emphasize a concept essential to understanding some aspect of geoscience in an introductory geology course. Each class involves the introduction of a key concept question or questions followed by ...
