ICESat-2 Bathymetry Training and Testing Database

Creator:

Ohlwiler, Ellery E., Ghartey, Charles E., McCullough, Ruth M., Parrish, Christopher E., Magruder, Lori A., Dietrich, James T., Holwill, Matthew, and Markel, Jonathan

Abstract:

NASA’s ICESat-2 satellite, which launched in 2018, carries the Advanced Topographic Laser Altimeter System (ATLAS), a green-wavelength, photon-counting lidar. While ICESat-2’s primary mission focuses on measurement of elevation of ice sheets, glaciers, sea ice, and vegetation, ATLAS has also proven remarkably effective at measurement of bathymetry, or water depths. However,...

Sizing Script for an Ox-centered, Jet-A/LOx Pintle Injector Engine

Creator:

Dimas-Harms, Colton R.

Abstract:

This script takes a short list of inputs as design requirements and recommends several possible engine configurations that will fit within the specified criteria. Many of the parameters can be directly solved from the specified inputs via basic relationships and equations; however, some output parameters require iteration across a range...

Creator:

Anderson, Andrew A.

Abstract:

We present a user study to investigate the impact of explanations on non-experts' understanding of reinforcement learning (RL) agents. We investigate both a common RL visualization, saliency maps (the focus of attention), and a more recent explanation type, reward-decomposition bars (predictions of future types of rewards). We designed a 124...
