Honeycomb materials possess high energy absorption characteristics and are useful for the impact protection of structural members. Various honeycomb configurations are being developed for a variety of applications. Analytical ...

This research involved the design of a position control system, based on a new method of observer-adaptive friction compensation, for a fuel valve that controls the flow of gas in large turbines. This fuel valve is ...

This dissertation presents the results of an investigation into the corrosion resistance of friction stir welding (FSW) for aerospace structures. Two of the most common aerospace aluminum alloys, 2024 and 7075, were ...

Among the different load conditions on a mechanical system, impact loading and its contribution to the design process require special consideration. The static methods of stress, strain, and deflection analyses are ...

Dynamic aircraft seat regulations are identified in the Code of Federal Regulations 1(CFR), 14 CFR Parts 23.562 and 25.562 for crashworthy evaluation of a seat in a dynamic environment. The regulations specify full-scale ...

Skin cancer affects many people worldwide and is life threatening without treatment. People with light skin, genetic diseases, and high exposure to ultraviolet radiation (UVR) are at a high risk of developing skin cancer. ...

This work is concerned with semi-globally and globally exponential observer/controllers for robotic plants. This dissertation work culminated in the following six [6] journal publications: 1. Malagari, S. and Driessen, ...

Thermal, rheological, and mechanical properties of a polymer composite cured at different one-stage and two-stage cure cycles were studied in this dissertation. A commercial carbon-fiber prepreg, Cycom 977-2 UD, was used. ...
