Using Motor Electrical Signature Analysis to Determine the Mechanical Condition of Vane-Axial Fans
… monitor motor rotor and attached axial fan for mechanical motion. The proof was to determine whether bearing faults and fan imbalances could be detected in vane-axial fans using Motor Electrical Signature Analysis (MESA). The data was statistically analyzed to determine if the MESA systems could …

Electrical characterization of carbon black filled rubber
… and capacitance have been measured under various conditions in an effort to electrically characterize and make electrical-mechanical correlations for 15 carbon black filled rubber samples. Resistance, conductance and capacitance have been monitored as functions of uniaxial compressive stress, …

CNC router modernization
… to bring the router online for use in the mechanical engineering curriculum. The router was cleaned and inspected; it was determined that the router was in sound mechanical condition. The stepper motors, control system, and power supply were also functional, but the CNC interface software …

Condition Monitoring Techniques for Wind Turbines
This thesis focuses on practical condition monitoring of wind turbines. With offshore wind playing an increasing part in UK electricity generation, prompt fault detection leading to preventative maintenance is gaining in importance. This work describes the development of a condition monitoring test …

Molecular Dynamics Simulations of Structural Transitions in Crystalline and Amorphous Inorganic Compounds
… in silica glass, depending on the thermo-mechanical condition at which the transitions take place. Macroscopically, reversible transitions are manifest in the anomalous thermo-mechanical behaviors of silica glass, such as an increase of the mechanical moduli upon expansion. Irreversible …
