Design and trade-offs of a pole-sitter mission [PDF]
This paper provides a mission analysis and systems design of a pole-sitter mission, i.e. a spacecraft that is continuously above an Earth Pole, and can provide real-time, continuous and hemispherical coverage of the polar regions.

Mission analysis and systems design of a near-term and far-term pole-sitter mission [PDF]
This paper provides a detailed mission analysis and systems design of a near-term and far-term polesitter mission. The pole-sitter concept was previously introduced as a solution to the poor temporal resolution of polar observations from highly inclined,

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

A database of plagioclase crystal preferred orientations (CPO) and microstructures – implications for CPO origin, strength, symmetry and seismic anisotropy in gabbroic rocks [PDF]
This study presents a unique database of 172 plagioclase Crystallographic Preferred Orientations (CPO) of variously deformed gabbroic rocks. The CPO characteristics as a function of the deformation regime (magmatic or crystal-plastic) are outlined and ...
