HazardNet: Road Debris Detection by Augmentation of Synthetic Models [PDF]
arXiv, 2023 We present an algorithm to detect unseen road debris using a small set of synthetic models. Early detection of road debris is critical for safe autonomous or assisted driving, yet the development of a robust road debris detection model has not been widely discussed.

Dynamics of space debris removal: A review [PDF]
arXiv, 2023 Space debris, also known as "space junk," presents a significant challenge for all space exploration activities, including those involving human-onboard spacecraft such as SpaceX's Crew Dragon and the International Space Station. The amount of debris in space is rapidly increasing and poses a significant environmental concern.

Formation of Phobos and Deimos via a Giant Impact [PDF]
Icarus 252 (2015) 334-338, 2015 Although the two moons of Mars, Phobos and Deimos, have long been thought to be captured asteroids, recent observations of their compositions and orbits suggest that they may have formed from debris generated by one or more giant impacts of bodies with ~ 0.01 x target mass.

Efficient solvers for shallow-water Saint-Venant equations and debris transportation-deposition models [PDF]
arXiv, 2021 This research is aimed at achieving an efficient digital infrastructure for evaluating risks and damages caused by tsunami flooding. It is mainly focused on the suitable modeling of debris dynamics for a simple (but accurate enough) assessment of damages. For different reasons including computational performance and Big Data management issues, we focus

Debris cover and surface melt at a temperate maritime alpine glacier: Franz Josef Glacier, New Zealand [PDF]
, 2012 Melt rates on glaciers are strongly influenced by the presence of supraglacial debris, which can either enhance or reduce ablation relative to bare ice.

Debris cloud of India Anti-Satellite Test to Microsat-R Satellite [PDF]
Heliyon 2020, 2020 Understanding the motion of debris cloud produced by the anti-satellite test can help us to know the danger of these tests. This study presents the orbit status of 57 fragments observed by the CelesTrak and presented in the NORAD Two-Line Element Sets of India Anti-Satellite Test.
