Feature space exploration as an alternative for design space exploration beyond the parametric space [PDF]
arXiv, 2023 This paper compares the parametric design space with a feature space generated by the extraction of design features using deep learning (DL) as an alternative way for design space exploration. In this comparison, the parametric design space is constructed by creating a synthetic dataset of 15.000 elements using a parametric algorithm and reducing its ...

Dispelling the myth of robotic efficiency: why human space exploration will tell us more about the Solar System than will robotic exploration alone [PDF]
Astronomy and Geophysics, Vol. 53, pp. 2.22-2.26, 2012, 2012 There is a widely held view in the astronomical community that unmanned robotic space vehicles are, and will always be, more efficient explorers of planetary surfaces than astronauts (e.g. Coates, 2001; Clements 2009; Rees 2011). Partly this is due to a common assumption that robotic exploration is cheaper than human exploration (although, as we shall ...

A newly revised estimation of bulk densities and examination of the shape of individual Ryugu grains
Earth, Planets and Space, 2023 The bulk density of grains from a celestial body is a fundamental property related to its composition and structure, contributing to the understanding of its evolutionary history. In this study, we provide the bulk density of 637 grains returned from the

Numerical Simulation of the Lunar Polar Environment: Implications for Rover Exploration Challenge
Aerospace, 2023 The lunar polar regions are key areas for future exploration due to the long-term continuous illumination and persistently shadowed regions that can cold trap abundant water and other volatiles.

Space exploration in neglect [PDF]
Brain, 1998 The present study investigated the gaze as well as the head and the eye-in-head movements of neglect patients while they were exploring their surroundings. A random configuration of letters was presented on the inner surface of a sphere that surrounded the subject, requiring free exploratory eye and head movements. The subjects were requested to search
