Surface charges in helium (a survey)
Soviet Journal of Low Temperature Physics, 1975A survey is made of theoretical and experimental results obtained so far pertaining to the characteristics of surface charges at the helium liquid-vapor interphase boundary. The electron states above a plane helium surface are described; the theory of interaction between surface electrons and thermal surface excitations in liquid helium is presented ...

Survey of Lunar Surface Mobility Systems
IFAC Proceedings Volumes, 1970Abstract Many devices for lunar surface mobility have been proposed and some are currently being developed. This paper briefly describes the various concepts, presents expected performance capabilities, and discusses characteristics peculiar to each mobility system. The lunar environment in which transporters must operate is also described.

Mapping—Surface or Ground Surveys
1984Preparation of vegetation maps from ground surveys as the first step in a field study is discussed. Depending upon the degree of accuracy required, various types of equipment are suggested for use in a mapping survey. Details are presented on station or point selections with a discussion of procedures and calculation of angles and distances using an ...
