Given the square matrices A,B,D,E and the matrix C of conforming dimensions, we consider
the linear matrix equation A\mathbfXE+D\mathbfXB=C in the unknown matrix \mathbfX. Our …

This paper presents a general state-space realization of the unsteady vortex-lattice method
together with a bespoke model-order reduction strategy. The aim is to provide a …

This research paper describes a study of the student professional competency development
as experienced by students in an upper-division project-based learning (PBL) curriculum …

Feedback control problems involving autonomous quadratic systems are prevalent, yet very
few software tools are available for approximating their solution. This paper represents a …

Vortex meandering is often characterized by seemingly stochastic motions of the vortex core.
An elucidation of the underlying mechanisms of core movement aids not only in …

We consider two algorithms to approximate the solution Z of a class of stable operator
Lyapunov equations of the form AZ+ ZA*+ BB*= 0. The algorithms utilize time snapshots of …

This paper presents a methodology for optimizing sample point selection in the context of
model order reduction (MOR). The procedure iteratively selects samples from a large …

This paper considers the problem of controlling a von Kármán vortex street (periodic
shedding) behind a circular cylinder using cylinder rotation as the actuation. The approach …

In this paper we describe a flexible and efficient new algorithm for model order reduction of
parameterized systems. The method is based on the reformulation of the parametric system …

Wakes of upswept afterbodies are often characterized by a counter-rotating streamwise
vortex pair. The unsteady dynamics of these vortices are examined with a spatio-temporally …
