This research presents development of L1 adaptive output-feedback control theory for a class of uncertain, nonlinear, and non-square multivariable systems. The objective is to extend the L1 adaptive control framework to ...

When trying to predict how and where ice will accrete on an aircraft, engineers first need to be able to track the path and concentration of water particles; this will allow for a better representation of water impingement ...

A large eddy simulation method for compressible channel flow simulations is developed and validated. The method separates the resolvable scale motions from the unresolvable (subgrid) scales by applying a spatial filter to ...

The study of aircraft icing is necessary to ensure the safety of commercial, military, and general aviation aircraft. The certification of modern commercial transports requires manufacturers to demonstrate that these ...

The correlation between the evolution of crystallite orientation in aramid fibers during loading and their mechanical and failure behavior were investigated. Three types of as-spun aramid fibers and a heat-treated type ...

The study on the effect of nanospheres on the mechanical property improvement of epoxies pointed to the fact that nanostructured materials provide improvements mainly on the toughness of an epoxy. In this regard, local ...

A pulse-forming electrical circuit is developed to reduce energy losses in the storage capacitor, and greater than 85% of the initial stored energy is transferred to the arc in a unipolar pulse. A high current diode installed ...

The Lower Atmosphere Ionosphere Coupling Experiment (LAICE) is a NanoSatellite which will be performing in-situ measurements of neutral and ion densities in the mesosphere, lower thermosphere, and ionosphere and correlating ...

In this thesis, multiple problems concerning the equilibrium and stability properties of thin deformable objects are considered, with particular focus given to the analysis of thin elastic rods. The problems considered can ...

In LiDAR Simultaneous Localization and Mapping (SLAM), probability distribution approximations of point clouds, such as the Normal Distribution Transform (NDT), can be leveraged for compact map storage and fast lookup. ...
