Soft robotic systems can offer several advantages including a decreased risk of injury from human-robot interactions, especially for medical robots, decreased risk of critical failure from impacts or crashes, and an ability to perform much more complex interactions with fluid surroundings, to name a few. However, these

MS Plan B Defense: Estimating marine atmospheric boundary layer stratification with synthetic aperture radar data
Jonathan B. Chapman, PE Department of Ocean & Resources Engineering University of Hawai‘i at Mānoa Location Information **This defense will be held both in person (Kuykendall Hall 101) and over Zoom** Meeting ID: 914 1679 5922 Passcode: 808795 https://hawaii.zoom.us/j/91416795922 Uncertainties in the lower atmosphere’s stratification, which is the balance between buoyancy and shear, lead to large uncertainties when determining air-sea fluxes. Previous works show that synthetic aperture radar (SAR) sea surface roughness images show atmospheric phenomena that are known to be related to stratification. In this project, we hypothesize that physics-guided neural networks (PGNNs) can be used to estimate

‘Artificial Intelligence’ for Flow Control and Data Analysis
https://hawaii.zoom.us/j/96162222366 Passcode: OREseminarDr. Siddhartha Verma, Assistant Professor Department of Ocean and Mechanical Engineering Florida Atlantic University Location Information **This seminar will be held over Zoom only** Meeting ID: 961 6222 2366 Passcode: OREseminar https://hawaii.zoom.us/j/96162222366 'Artificial Intelligence' has made tremendous gains in recent years, and it is increasingly finding promising uses in various practical and scientific applications. But despite our optimistic outlook, the underlying algorithms do not possess 'intelligence' in the true sense of the word. Instead, they are extremely adept at identifying non-linear patterns in high-dimensional datasets. I will highlight how we have leveraged such algorithms to discover optimal control laws in
