Flapping Wing Flight Dynamic Modeling
… quasi coordinate Lagrangian scheme while the aerodynamic forces are calculated using quasi-steady potential flow aerodynamics. Trim solutions are calculated using periodic shooting for several different conditions including hover, climb, and forward flight. The stability of the trim is calculated …

Inverse dynamic modeling for characterization of spasticity
… the pendulum knee drop test. Inverse kinematic modeling is implemented to investigate the pathophysiology of spasticity. Using the equilibrium point hypothesis as a conceptual framework to explain disabled and non-disabled neuromuscular control, it has been demonstrated that the equilibrium …

Dynamic modeling and analysis of oscillatory bioreactors
Dynamic modeling of bioreactors is a challenging problem. The complexity of first principle models also make model validation and analysis very difficult and model-based controller design practically intractable. This thesis has focused on finding an effective tool for model dynamic analysis, …

Dynamic Modeling of Soft Robotic Dielectric Elastomer Actuator
… The presented research proposes a model for the dynamical characterization of multilayer DEAs in the mechanical and electrical domain. The analytical model is derived by using free body diagrams and lumped parameters that recreate an analogous system representing the multiphysics dynamics within …

Non-linear dynamic modeling using component mode synthesis
Dynamic simulations provide insight into the operation of complex mechanisms under dynamic loading conditions. These types of analyses are important to understand design margins and assure that a product meets its functional requirements during all operational environments. Rigid body dynamic …

Dynamic Modeling With Implicit Surfaces and Polygonal Meshes
"Morse theory reveals the topological structure of a shape based on the critical points of a real function over the shape. This thesis solves a relaxed form of Laplace's equation to find a ""fair"" Morse function with a user-controlled number and configuration of critical points."

Design and dynamic modeling of waste stabilization ponds
… stage in the city of Tatui, Brazil. An existing dynamic "bio-geo-chemical" waste stabilization pond model is reviewed and modified. The modified model is used to fit data from the anaerobic lagoon of a wastewater treatment facility in Riviera de Sao Lorenco. The model is also fit onto aerated …

Compressible Convection and Subduction: Kinematic and Dynamic Modeling
Subduction is a dynamic and time-dependent process which requires time-dependent models for its study. In addition, due to the very high pressures within the Earth's interior, an evaluation of the role of compressibility in subduction studies should be undertaken. However, most subduction studies …

New components for dynamic modeling of transient thermal systems
This work presents several novel components for the MATLAB Simulink® toolbox THERMOSYS™. The first component is a universal heat exchanger, which can behave either as an evaporator or a condenser as the refrigerant properties dictate. The second component is a liquid-to-solid heat exchanger, which …
