Exploring Space Exploring Earth [PDF]
Eos, Transactions American Geophysical Union, 2003 The preface of Exploring Space Exploring Earth states that its objective is “…to explore the impact of space flight on geology and its subsurface counterpart, geophysics…” As promised, some of the book's chapters deal with geophysics—space geodesy, satellite studies of geomagnetism, and remote sensing. Others cover geology—impact cratering, terrestrial

HAC Explore: Accelerating Exploration with Hierarchical Reinforcement Learning [PDF]
arXiv, 2021 Sparse rewards and long time horizons remain challenging for reinforcement learning algorithms. Exploration bonuses can help in sparse reward settings by encouraging agents to explore the state space, while hierarchical approaches can assist with long-horizon tasks by decomposing lengthy tasks into shorter subtasks. We propose HAC Explore (HACx), a new

An Exploration into Fern Genome Space [PDF]
Genome Biology and Evolution, 2015 Ferns are one of the few remaining major clades of land plants for which a complete genome sequence is lacking. Knowledge of genome space in ferns will enable broad-scale comparative analyses of land plant genes and genomes, provide insights into genome evolution across green plants, and shed light on genetic and genomic features that characterize ...

RACER: Rapid Collaborative Exploration with a Decentralized Multi-UAV System [PDF]
arXiv, 2022 Although the use of multiple Unmanned Aerial Vehicles (UAVs) has great potential for fast autonomous exploration, it has received far too little attention. In this paper, we present RACER, a RApid Collaborative ExploRation approach using a fleet of decentralized UAVs.

Estimation of Mode Transition in a Supersonic Combustor
Journal of Thermal Science and Technology, 2013 A quasi-one dimensional calculation was carried out to figure out supersonic combustor performances. Three flow tubes were considered in the combustor region. Those were an air-flow-tube, a combustion-flow-tube and a fuel-flow-tube.

Systematic design space exploration by learning the explored space using Machine Learning [PDF]
arXiv, 2023 Current practice in parameter space exploration in euclidean space is dominated by randomized sampling or design of experiment methods. The biggest issue with these methods is not keeping track of what part of parameter space has been explored and what has not.

Insights into the formation and evolution of extraterrestrial amino acids from the asteroid Ryugu
Nature Communications, 2023 Amino acid concentrations from 2 particles returned from different touchdown sites on the surface of Ryugu are reported. Differences in chemistry suggest different levels of aqueous alteration are recorded at the 2 sampled locations.
