The InSight HP³ Penetrator (Mole) on Mars: Soil Properties Derived From the Penetration Attempts and Related Activities
(2021)arXivThe NASA InSight Lander on Mars includes the Heat Flow and Physical Properties Package HP3 to measure the surface heat flow of the planet. The package uses temperature sensors that would have been brought to the target depth of 3--5 m by a small penetrator, nicknamed the mole. The mole requiring friction on its hull to balance remaining recoil from its hammer mechanism did not penetrate to the targeted depth. Instead, by precessing about ...Working Paper -
Human Gait-labeling Uncertainty and a Hybrid Model for Gait Segmentation
(2021)TechRxivMotion capture systems are widely accepted as ground-truth for gait analysis and are used for the validation of other gait analysis systems.To date, their reliability and limitations in manual labeling of gait events have not been studied. Objectives: Evaluate human manual labeling uncertainty and introduce a new hybrid gait analysis model for long-term monitoring. Methods: Evaluate and estimate inter-labeler inconsistencies by ...Working Paper
