The performance of several widely-known methods for analyzing data utilizing nonlinear mixed effects models are evaluated via simulation in two settings. Each setting is a hierarchical mixed effects model in which repeated observations on a subject are modeled by subject-specifi…

The objectives of this research work are to develop direct and indirect adaptive control strategies for discrete-time nonlinear systems and to investigate the applicability of the proposed schemes to adaptive tracking control of a flexible-link manipulator. The first problem con…
The two-photon absorption (TPA) coefficient is measured in indium phosphide (InP) using femtosecond pulses to be 45cm/GW at 1.32μm. Nanosecond pulses are subsequently used to find the free-carrier refractive index cross-section, σ_r, and the free-carrier absorption coefficient, …
Longitudinal optical binding refers to the light induced self organisation of micro particles in one dimension. In this thesis I will present experimental and theoretical studies of the separation between two dielectric spheres in a counter-propagating (CP) geometry. I will expl…
Most engineering systems encountered in practice exhibit significant nonlinear behavior. For control of systems exhibiting nonlinearities, the normal design procedure is to construct a linearized approximation of the process model followed by the application of a linear control …
