Design optimization methods for additively manufactured natural convection heatsinks
(2021-12)
With 3-D printing technology becoming more widely available, designs with complex geometries are now feasible to manufacture. The ability to create complex geometries opens many new possibilities in the optimization field. ...
Measurement and magnitude-based system identification of tornado-associated infrasound
(2021-07)
Recent evidence indicates that acoustic waves at frequencies below human hearing (infrasound) are produced during tornadogenesis and continue through the life of a tornado. The currently available tornadic infrasound data ...
Inflow analysis for multi-rotors and the impact on sensor placement
(2021-07)
As the usage of small multi-rotor unmanned aircraft systems (sUAS) continues to grow there is a need to understand the complex flow-field and its interactions with the propellers and the sUAS airframe. It is particularly ...
This blows?: Evaluation of additive manufactured five hole probes for unmanned system based wind measurements
(2021-07)
A deep understanding of the wind in the atmosphere is becoming valuable as unmanned aerial systems (UAS) are integrated into the National Airspace System. Unmanned vehicles are also becoming a key tool in weather observation ...
Impact of vibration and stochastic resonance electrical stimulation on muscle contraction
(2021-05)
Motivated by possible applications in pain management and improved prognosis, this study looks into the different methods of potential intervention methods to reduce joint contact forces in the upper and lower extremities. ...
Implementation of a local path planning algorithm for unmanned aerial vehicles
(2021-07)
