Complex Surface Fabrication Via Developable Surface Approximation: A Survey
IEEE Transactions on Visualization and Computer GraphicsComplex surfaces are commonly observed in various applications and have significant value in enhancing comfort, aesthetics, and functionality. However, their fabrication often involves complex and costly processes. To simplify the fabrication difficulty, significant research has focused on using 3D developable surfaces to approximate target 3D surfaces.

Survey on Discrete Surface Ricci Flow
Journal of Computer Science and Technology, 2015Ricci flow deforms the Riemannian metric proportionally to the curvature, such that the curvature evolves according to a nonlinear heat diffusion process, and becomes constant eventually. Ricci flow is a powerful computational tool to design Riemannian metrics by prescribed curvatures.

A borehole‐to‐surface electromagnetic survey
GEOPHYSICS, 1995The results of a limited field trial confirm the usefulness of borehole‐to‐surface electromagnetic (EM) measurements for monitoring fluid extraction. A vertical EM profiling experiment was done at the University of California Richmond Field Station, where we simulated a brine spill plume by creating a saline water injection zone at the depth of 30 m ...

Leveling airborne and surface gravity surveys
Applied Geomatics, 2021For both airborne gravimetric and airborne magnetic surveys, systematic residual errors usually remain in the data after standard data processing. In the literature, the mismatches at the crossover points are used to either adjust the processing procedures or directly adjust the results. This is usually called crossover adjustment.

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 ...

A Survey on Implicit Surface Polygonization
ACM Computing Surveys, 2015Implicit surfaces (IS) are commonly used in image creation, modeling environments, modeling objects, and scientific data visualization. In this article, we present a survey of different techniques for fast visualization of IS. The main classes of visualization algorithms are identified along with the advantages of each in the context of the different ...

A Survey of Pluto’s Surface Composition
2018Pluto was discovered less than 100 years ago (in 1930) by Clyde Tombaugh at Lowell Observatory in Flagstaff, AZ. The founder of the observatory, Percival Lowell, had initiated a systematic search of the sky to find the putative Planet X in 1905 (Tombaugh 1960).

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.
