Fluid dynamic mechanisms of power augmentation in vertical axis wind turbines
Alexander, Aaron (2018-07)Using computational fluid dynamics (CFD) simulations, this study examines passive flow control in drag-based and lift-based vertical axis wind turbines (VAWT). In drag based VAWTs (D-VAWT) such as the Savonius wind turbine, ... -
Holistic indoor scene understanding by context supported instance segmentation
Guo, Lin (2020-12)Intelligent robots require advanced vision capabilities to perceive and interact with the real physical world. While computer vision has made great strides in recent years, its predominant paradigm still focuses on building ... -
Ice Accretion on Small Unmanned Aircraft
Avery, Alyssa Shearon (2019-07)Aircraft icing is an important and complex problem. Small unmanned aerial systems are becoming increasingly common in high quality operations. The hazards of icing on these smaller aircraft are significant and primarily ... -
Identification of weather information gaps for general aviation and uncrewed operations
Wallace, J. W. (2022-07)Uncrewed Aircraft Systems (UAS) represent a rapidly growing industry, with a market value of $20.8 billion in 2021 projected to grow to half a trillion dollars in 2028, and Urban Air Mobility is projected to grow from $3 ... -
Impact of vibrations on mobile infrasound sensing and the development of a custom sensor package
Lindsey, Bryce B. (2023-05)Acoustic frequencies below 20 Hz, referred to as "infrasound", are emitted by various phenomena. Events such as volcanoes, tornadoes, earthquakes, industrial processes, detonations, and bolides, can be analyzed via the ... -
Intent Communication Between Autonomous Vehicles and Pedestrians
Matthews, Milecia (2016-05-01)When pedestrians encounter vehicles, they typically stop and wait for a signal from the driver to either cross or wait. What happens when the car is autonomous and there isn't a human driver to signal them? This paper seeks ... -
Investigation of Low-Profile Vortex Generators via Computational Methods
Wilson, Trevor (2019-07)A unique low-profile vortex generator, termed the Conformal Vortex Generator (CVG), has recently been discovered to provide fuel saving of greater than 1% on commercial aircraft. The CVG is an adhesive backed film that ... -
Investigation of Low-Profile Vortex Generators via Experimental Methods
KC, Real (2019-07)A novel low-profile vortex generator has recently demonstrated fuel savings of 1% on commercial aircraft. It has been termed a Conformal Vortex Generator (CVG) and consists of a backward facing step where the chord position ... -
Locomotion of a cylindrical rolling robot with a shape changing outer surface
Puopolo, Michael Gerald (2017-03)A cylindrical rolling robot is developed that generates torque by changing shape (eccentricity) of its elliptical outer surface. Shape change commences four times per revolution, whenever one of four elliptical axes rotates ... -
Model-data fusion in digital twins of large scale dynamical systems
Ahmed, Shady E. (2022-07)Digital twins (DTs) are virtual entities that serve as the real-time digital counterparts of actual physical systems across their life-cycle. In a typical application of DTs, the physical system provides sensor measurements ... -
Modeling and failure analysis of composite I-beams for UAV wing spar design
Watkins, Zachary Taylor (2021-05)In unmanned aerial systems (UAS), the composite I-beam using carbon fiber caps and a cross-grain balsa shear web is often used for the main spar. This manufacturing method is underdeveloped in analysis causing engineers ... -
Modeling web handling systems and a method for determining feedback controller gains
Reish, Benjamin David (2020-07)Modeling the longitudinal dynamics and control of web handling systems requires accurate models of the primitive elements involved, and an understanding of the processes used for speed and tension control. Primitive elements ... -
