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 Delaunay Surfaces with Applications in Capillary Surfaces
Journal of Geometry and Symmetry in Physics, 2022In this paper we survey Delaunay surfaces in $\mathbb{R}^{3}$ spanning two coaxial circles which appear as capillary surfaces supported on different solid supports in the absence of gravity. We classify these surfaces based on contact angles and the geometry of the support. Numerical solutions of the Euler Lagrange equation are provided using numerical

Surface Magnetic Resonance (SMR) Surveys
2022This animation shows how Surface Magnetic Resonance (SMR) Surveys are conducted. It is part of a series of Field Activity Technique Engagement Animations. The target audience are the communities that are impacted by GA's data acquisition activities. There is no sound or voice over. The 2D animation includes a simplified view of what SMR equipment looks

Surfaces that show scale invariance are abundant in Nature and in the literature. There are many ways that such scale invariance may manifest itself and unfortunately this has led to the introduction of many different concepts in the literature. It is the aim of this short review to systematize and clarify the relations between these different concepts.

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.
