Atterburg Limits
(2014-02-06)
Atterberg Limits describe the water contents at which clays change behavior. The water content indicating the division between the liquid and plastic state is the liquid limit. The Liquid Limit is determined using a brass ...
The Role of Breccia Lenses in Regolith Generation From the Formation of Small, Simple Craters: Application to the Apollo 15 Landing Site
(2023-01-18)
Impact cratering is likely a primary agent of regolith generation on airless bodies. Regolith production via impact cratering has long been a key topic of study since the Apollo era. The evolution of regolith due to impact ...

(2017-10-26)
Team 3 consists of six members working together to design and build a fully autonomous shopping cart. The purpose of the cart is to perform as a personal shopping assistant to the user as he/she shops in different environments. ...
Automatically identifying, counting, and describing wild animals in camera-trap images with deep learning
(2020-07-27)
Having accurate, detailed, and up-to-date information about the location and behavior of animals in the wild would improve our ability to study and conserve ecosystems. We investigate the ability to automatically, accurately, ...
Discrimination experiments with the U.S. Army's standard metal detector
(2022-10-25)
[1] Discrimination experiments with the U. S. Army's standard hand-held metal detector (AN/PSS-12) are described. An appendix describes the functioning of the device as a metal detector, and the body of the paper discusses ...
Forest restoration as a strategy to mitigate climate impacts on wildfire, vegetation, and water in semiarid forests
(2020-05-18)
Climate change and wildfire are interacting to drive vegetation change and potentially reduce water quantity and quality in the southwestern United States, Forest restoration is a management approach that could mitigate ...
No Change in the Recent Lunar Impact Flux Required Based on Modeling of Impact Glass Spherule Age Distributions
(2020-05-27)
The distributions of Ar-40/Ar-39-derived ages of impact glass spherules in lunar regolith samples show an excess at <500 Ma relative to older ages. It has not been well understood whether this excess of young ages reflects ...
