A hypothetical rock whose composition is thought to be similar to the average chemical composition of the outermost 10-mile (16-kilometer) shell of the earth.McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc. ...
The Haversine formula is considered to be accurate to within 0.5% of the true distance between two points. However, this accuracy may vary depending on the distance between the points and the curvature of the Earth's surface in that area.5...
aWe found similar results to earlier studies on contour detection: detection was better for contrast flicker than for orientation flicker, and detection performance was curvature-dependent for orientation flicker but not for contrast flicker W我们发现了近似结果到关于等高侦查的更早的研究: 侦查为对比忽悠...
LOW —a center of pressure surrounded on all sides by higher pressure; also called a cyclone. Cyclonic curvature is the curvature of isobars to the left when you stand with lower pressure to your left. HIGH —a center of pressure surrounded on all sides by lower pressure, also called an ...
On the one hand the determination of the earth radius and oblateness from a few local triangulations, especially in mountainous country, would be wellnigh impossible. On the other hand, given methods that perform suitable averages over the sharp fluctuations of the earth's surface (such as ...
aGandhi and Raval (2006) developed the analytical model to estimate the top roller position as a function of desired radius of curvature, for multiple pass three-roller forming of cylinders, considering real material behavior and change of Young’s modulus of elasticity(E) under deformation and ...
Let EP(f ) ⊂ MP(f ) denote the set of all ergodic measures. A function F : Ω× M → R is called random continuous function, if x → F ... Y Cao - 《Journal of Differential Equations》 被引量: 40发表: 2006年 Convolution, curvature, and combinatorics: a case study The articl...
Abe, et al. further teaches flat surfaces within the device, but these flat surfaces are on the protective cap outer diameter where the cylindrical distortions are of far lesser concern than on the fiber outer diameter and cap inner diameter where the curvature is much higher and the refractive...
During unit-gradient flow, the matric potential corresponding to the mean curvature of the menisci should provide a good approximation of the intrinsic phase average of the matric potential.doi:10.5194/hessd-7-6491-2010G. H. de RooijCopernicus GmbHHydrology and Earth System Sciences Discussions...
LC measures surface curvature. By applying various kernel matrices to the DEM, LC quantifies the convexity or concavity of the terrain: 𝑐𝑜𝑛𝑣=[𝑒𝑙𝑒𝑣]:𝑘𝑒𝑟𝑛𝑒𝑙𝐿𝐶conv=elev:kernelLC (6) where kernelLC is a kernel matrix and conv is the resulting con...
