Design of optimal Earth pole-sitter transfers using low thrust propulsion [PDF]

, 2011
Recent studies have shown the feasibility of an Earth pole-sitter mission using low-thrust propulsion. This mission concept involves a spacecraft following the Earth's polar axis to have a continuous, hemispherical view of one of the Earth's poles.

Reconstruction of incomplete X-ray diffraction pole figures of oligocrystalline materials using deep learning

Scientific Reports, 2023
X-ray diffraction crystallography allows non-destructive examination of crystal structures. Furthermore, it has low requirements regarding surface preparation, especially compared to electron backscatter diffraction. However, up to now, X-ray diffraction

Generalized pole figures from post-processing whole Debye–Scherrer patterns for microstructural analysis on deformed materials

Journal of Synchrotron Radiation, 2022
Debye–Scherrer patterns, obtained from X-ray diffraction experiments using synchrotron light in transmission geometry, were analysed to construct generalized pole figures, and further used as input for an orientation distribution function inversion ...

3D MORPHOLOGICAL ANALYSIS OF COMPOSITE MATERIALS WITH AGGREGATES OF SPHERICAL INCLUSIONS

Image Analysis and Stereology, 2011
Composite materials containing aggregates of spherical inclusions are studied from 3D images obtained by X-ray microtomography. Using two point statistics in different directions, and the empirical distribution of orientations of pairs of inclusions ...

Changer in the texture orientation of electrolytic nickel by cold air plasma

Литьë и металлургия, 2020
The effects of cold air plasma influence on the change in the microstructure, stress state and texture of the cathode nickel brand H-1 were studied. By the method of target metallography it has been established that the microstructure does not change ...

Race to the Pole: Matthew Henson, Arctic Explorer

American Studies in Scandinavia, 2022
In his memoir, A Negro Explorer at the North Pole (1912), Matthew Henson describes the toll of his and Peary’s race to the Pole. This record of the 1908-09 Arctic expedition complicates established understandings of the “Dash to the Pole” and his own ...
