Electrospray thrusters provide small, precise thrust with high power efficiencies and variable specific impulses from less than 1000s to over 4000s. The miniaturization and clustering of many emitters together is essential ...

The purpose of the work in this thesis was to develop a finite element model of a helmet with various additional protective devices and to investigate how the personal protective equipment system affects the mechanical ...

The piston ring pack friction is a major contributor to the internal combustion engine mechanical friction loss. The oil control ring decides the oil supply to the top two rings in addition to being the major friction ...

It is an undeniable fact that autonomous systems are simultaneously becoming more common place, more complex, and deployed in more inhospitable environments. Examples include smart homes, smart cars, Mars rovers, unmanned ...

This thesis presents a path planning and control strategy that enables an unmanned non-holonomic vehicle to intercept a fast moving object. The path planning is performed under model uncertainty, with respect to the vehicle's ...

State of the art CubeSats such as ExoplanetSat require pointing precision for the science payload on the order of arcseconds. ExoplanetSat uses dual stage control to achieve the pointing requirement. Reaction wheels provide ...
