Autonomous Multirotor Landing on Landing Pads and Lava Flows [PDF]
arXiv, 2022 Landing is a challenging part of autonomous drone flight and a great research opportunity. This PhD proposes to improve on fiducial autonomous landing algorithms by making them more flexible. Further, it leverages its location, Iceland, to develop a method for landing on lava flows in cooperation with analog Mars exploration missions taking place in ...

, 1999 Animating lava flowing down the slopes of a volcano brings several challenges: modeling the mechanical features of lava and how they evolve over time depending on temperature; computing, in a reasonable time, the interactions inside the flow, and between the flow and a complex terrain data-base; and lastly, rendering the visual aspect of the flow.

Could fresh lava be (warm) dark matter? [PDF]
arXiv, 2022 Dark matter models can be classified according to their impact on the properties of galaxies, including cold dark matter (CDM), warm dark matter (WDM), self-interacting dark matter (SIDM) and fuzzy dark matter (FDM). In celebration of April Fool's Day, and also of the 1-year anniversary of the start of the 2022 volcanic eruption at Fagradalsfjall here ...

Deep Underground Science and Engineering, EarlyView.The present study uses the Modified Mohr‐Coulomb true‐triaxial failure criterion (MMC_TT), which predicts the strength of rock better than the MGC criterion in laboratory true‐triaxial tests to overcome the limitations. Moreover, based on the data from previously published five vertical wells in the Krishna‐Godavari basin (K‐G basin), an empirical ...

LAVA: Language Audio Vision Alignment for Contrastive Video Pre-Training [PDF]
arXiv, 2022 Generating representations of video data is of key importance in advancing the field of machine perception. Most current techniques rely on hand-annotated data, which can be difficult to work with, expensive to generate, and hard to scale. In this work, we propose a novel learning approach based on contrastive learning, LAVA, which is capable of ...

InfoMat, EarlyView.We printed various 3D conductive microdome geometries using a single direct printing method. Hierarchical dome structures provide linear and sensitive pressure sensing. We applied the hierarchical dome‐structured pressure sensor to a robotic finger, demonstrating its effectiveness in shine muscat harvesting, fine needle sensing, and droplet control ...

Experimental constraints on the rheology, eruption and emplacement dynamics of analog lavas comparable to Mercury's northern volcanic plains [PDF]
J. Geophys. Res. Planets, 122, doi:10.1002/2016JE005181, 2017 We present new viscosity measurements of a synthetic silicate system considered an analogue for the lava erupted on the surface of Mercury. In particular, we focus on the northern volcanic plains (NVP), which correspond to the largest lava flows on Mercury and possibly in the Solar System.
