On equivalency of various geometric structures [PDF]
, 2013 In the literature we see that after introducing a geometric structure by imposing some restrictions on Riemann-Christoffel curvature tensor, the same type structure given by imposing same restriction on other curvature tensors being studied.

Estimating the Rut Depth by UAV Photogrammetry
Remote Sensing, 2017 The rut formation during forest operations is an undesirable phenomenon. A methodology is being proposed to measure the rut depth distribution of a logging site by photogrammetric point clouds produced by unmanned aerial vehicles (UAV).

The Lemon Illusion: Seeing curvature where there is none
Frontiers in Human Neuroscience, 2015 Curvature is a highly informative visual cue for shape perception and object recognition. We introduce a novel illusion—the Lemon Illusion—in which subtle illusory curvature is perceived along contour regions that are devoid of physical curvature.

Stability of Curvature Measures [PDF]
, 2008 We address the problem of curvature estimation from sampled compact sets. The main contribution is a stability result: we show that the gaussian, mean or anisotropic curvature measures of the offset of a compact set K with positive $\mu$-reach can be ...

Fiber Microsphere Coupled in a Taper for a Large Curvature Range
Fibers, 2019 This work consists of using an optical fiber microsphere as a sensor for a wide range of curvature radii. The microsphere was manufactured in a standard fiber with an electric arc.

Influence of Surface Curvature on Coanda Effect for Vertical Jet Impacting Horizontal Cylinder [PDF]
Journal of Applied Fluid Mechanics, 2023 The Coanda effect is a tendency of flowing fluid to follow the solid surface rather than to separate under the inertial effect. This paper presents the effects of surface curvature on the Coanda angle and jet deflection for a vertical jet impacting a ...
