Hypsometric and geometric controls on hydrodynamics, tidal asymmetry, and sediment connectivity in shallow estuarine systems
… elucidation of some of the relationships between geometric parameters and forcing mechanisms applicable to many shallow coastal systems.

Error analysis for harmonic tracking algorithm using geometric control
Geometric Control Theory was initiated in the beginning of the 1970's and has now became a well established approach in addressing problems of tracking and disturbance rejections of time independent and dependent signals. This thesis describes the error analysis for time-dependent harmonic signal …

Design, Analysis, and Optimization of Vibrational Control Strategies
… the problem to a constrained optimization one. Geometric control theory provides powerful tools for studying the control properties of control-affine systems. Using the concepts of vibrational and geometric controls and averaging tools, a closed-loop control strategy for trajectory tracking of a …

Controlling the collective dynamics in systems of active oscillators through geometry and hydrodynamic entrainment
… cilium by a rigid sphere that is driven by a geometrically updated force. The simplicity of the model lends itself to generic results that could be observed in many systems with hydrodynamic coupling. This thesis is broken into two main parts. The first focuses on developing an analytical …

Multiphase Flow Dynamics in Confined Domains—A DNS Study of Bubbly, Thermal and Riblet-Induced Turbulence
… (HBR) and length blockage ratio (LBR) as key geometric controls, systematically mapping transition thresholds. The results reveal that increasing riblet height or decreasing riblet spacing lowers the critical Reynolds number, with nonlinear destabilization observed for $0.2 \leq HBR \leq …
