The difference between the reciprocals of the radii of curvature of the two surfaces of a lens. McGraw-Hill Dictionary of Scientific & Technical Terms, 6E, Copyright © 2003 by The McGraw-Hill Companies, Inc. The following article is fromThe Great Soviet Encyclopedia(1979). It might be outd...
understand the concepts of lens formula, magnification and power of lens concave lenses when an object is placed at infinity, a virtual image is formed at the focus. the size of the image is highly diminished and point size. when an object is placed at a finite distance from the lens, a...
curvature between two brain regions considers the strength of connection between those two brain regions in the context of the rest of the brain. This measurement takes into account the context of a brain region pair and serves as a useful lens through which to analyze the robustness of the ...
We note that a convergence result for the curvature of also can be obtained after changing variables (see also Theorem 3.12 for the meaning of the convergence). The convergence also will be proved in the proof of Theorem 1.2. As we mentioned, Shimojo and the author [21] proved the uniform...
Establishing the refraction of the eye during surgery, i.e. intraoperatively, is of importance in a number of types of eye surgery. Examples thereof include the working of the corneal surface by means of laser beams to correct defective vision and cataract operations, in which the lens of the...
Scanner 116 passes the 8 mm beam through a two-axis galvanometer and then focuses the beam on back surface 22 through a flat-field objective lens. The two-axis galvanometer includes a set of two mirrors that allow planar x-y motion of the focused beam on the work surface of slider 10...
Involves the conversion of non-numeric values to numeric values, a process commonly applied to categorical features representing qualitative data without inherent mathematical meaning. While easily comprehensible to humans, such data poses challenges for computers. Consequently, all categorical data are trans...
By combining both quantities, our measure can account for a long path in a small “radius”, meaning a long path that stays in the vicinity of the starting word. When the “radius” quantity stays constant, the contribution of path length is the reverse of what occurs in the greedy approa...
Note that the additive term − 1 / λ in the above definition of G λ , f ( x ) = 1 λ ( e λ f ( x ) − 1 ) is not necessary; it is included so that lim λ → 0 G λ , f ( x ) = f ( x ) , meaning that in the limiting case of zero-convexity is just ...
From the angle of supervision the paper applies the modern quality management meaning and mainly introduces the supervision measure and method of pushing axis control by shield with small curvature radius. 该文从监理的角度,运用现代质量管理手段着重介绍了小曲率半径盾构推进轴线控制的监理措施和方法。 更...
