Quasi-stability and Exponential Attractors for A Non-Gradient System---Applications to Piston-Theoretic Plates with Internal Damping

Autor: Howell, Jason S., Lasiecka, Irena, Webster, Justin T.

We consider a nonlinear (Berger or Von Karman) clamped plate model with a {\em piston-theoretic} right hand side---which include non-dissipative, non-conservative lower order terms. The model arises in aeroelasticity when a panel is immersed in a hig

Dual-Mixed Finite Element Methods for the Navier-Stokes Equations

Autor: Howell, Jason S., Walkington, Noel J.

A mixed finite element method for the Navier-Stokes equations is introduced in which the stress is a primary variable. The variational formulation retains the mathematical structure of the Navier-Stokes equations and the classical theory extends natu

Dynamic Modeling of Nontargeted and Targeted Advertising Strategies in an Oligopoly

Autor: Fletcher, Chloe A., Howell, Jason S.

With the growing collection of sales and marketing data and depth of detailed knowledge of consumer habits and trends, firms are gaining the capability to discern customers of other firms from the potential market of uncommitted consumers. Firms with

Prestructuring sparse matrices with dense rows and columns via null space methods

Autor: Howell, Jason S.

Several applied problems may produce large sparse matrices with a small number of dense rows and/or columns, which can adversely affect the performance of commonly used direct solvers. By posing the problem as a saddle point system, an unconventional
