Analysis of passive and active discrete-distributed linear dynamical systems using Green's function methods
… of a large class of linear passive discrete-distributed mechanical systems has been performed, unifying and extending previous results in the field. A distributed parameter system, represented by the Green's function of its governing differential equation, and a multiplicity of arbitrarily …

Modeling, Approximation, and Control for a Class of Nonlinear Systems
… estimation, and control for classes of nonlinear systems whose state evolves in space $mathbb{R}^n times H$, where $mathbb{R}^n$ is a n-dimensional Euclidean space and $H$ is a infinite dimensional Hilbert space. Specifically, two classes of nonlinear systems are studied in this dissertation. The …

Parameter identification in distributed structures
… two new techniques for the identification of parameters in distributed-parameter systems. The first technique identifies the physical parameter distributions such as mass, damping and stiffness. The second technique identifies the modal quantities of self-adjoint distributed-parameter systems. …

A method for approximating and controlling the distributed parameter model of a MIMO chemical diffusion system
… is an important factor in many biological systems. Chemotaxis, the directed movement of an organism in response to chemical in its environment, is known to be a prominent driver in the directed growth of new blood vessels from pre-existing ones, a phenomenon called angiogesis. In order to …

New Models for Crowd Dynamics and Control
… relationship, while the other three models are systems of hyperbolic partial differential equations. For one of the system models presented, we show how it can be derived independently from a microscopic crowd model. The models are nonlinear, time-varying, hyperbolic partial differential …

A Wavelet-Based Rail Surface Defect Prediction and Detection Algorithm
… consisting of operating conditions and physical parameters. To generate this training data, a dynamic wheel-rail interaction model was developed that relates defect geometry to the side frame vertical acceleration signature. The model was generated by using combined systems dynamic modeling, and …
