Alignment determination of the Hayabusa2 laser altimeter (LIDAR)

open access: yesEarth, Planets and Space, 2021
In this study, we determined the alignment of the laser altimeter aboard Hayabusa2 with respect to the spacecraft using in-flight data. Since the laser altimeter data were used to estimate the trajectory of the Hayabusa2 spacecraft, the pointing ...

Space exploration in neglect [PDF]

open access: yesBrain, 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

Feature Space Exploration as an Alternative for Design Space Exploration Beyond the Parametric Space

open access: yesCAADRIA proceedings, 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 ...
