Accurately calculate the curvature on the ball Earth. Uses a cosine function, works for all distances in both kilometers and miles. Open source on Github.
a real-life scenario, our calculator might be slightly wrong in some cases. Why does this happen? Does it mean the Earth is flat and doesn't curve at all? Of course not! It just means that our calculator doesn't account for the phenomenon of refraction. When light travels through a ...
In the present study, a curved line is assumed to be the information source, and the macroscopic shape information is the entropy, expected angle variation, and curvature variation of the curve. These values are described below. 2.1. Angle Variation The entropy and expected angle variation are ...
Also, lenses generally exhibit field curvature: focal points for incidence from different directions lie on a curve rather than a plane. Further, there are image distortions, e.g. in the form of barrel, pincushion or mustache distortions. Chromatic aberrations arise from the chromatic dispersion ...
Points corresponding to curve coefficients are arranged in a Hough space by a Hough conversion means 5. Positions of points arranged in this Hugh space are obtained by a Hough conversion curve detection means 6, and formulas on the image face of white lines on the road are calculated.YASUI ...
圆弧弯道 1. This article introduced one kind of entire station survey meter,together with the CASIO series programmable calculator,which carries on to the tunnel circular arc curve is surveys. 介绍了一种利用全站仪,结合CASIO系列可编程计算器进行隧洞圆弧弯道测设的新方法。补充...
I must admit that I am a bit of a battleship junkie. I have been reading some old US Navymanualson battleship fire control, which discuss the various effects that must becorrectedfor to ensure accurate fire (Figure 1). In this post, I want to examine how the curvature of the Earth ...
The method, with total station or range instruments and calculator, is not only quick and convenient, but also results in higher precision in the measure of count positions of long combination curve in the construction of highways. 介绍了利用线路平面控制网的控制点测设道路工程中组合曲线中线桩点位...
Shape-generation method using curvature entropy - Ujiie, Matsuoka - 2000 () Citation Context ...entropy, while Section 4 improves the proposed entropy in an effort to evaluate the continuity of a curve and to analyze the difference between the two proposed entropies. Based on our previous ...
A calculator circuit (4) is connected to the shunt to calculate the first (I') and second (I'') derivatives of the current flow as a function of time. These values (I, I', I'') are compared in an analyser circuit (5) with amplitude and sign reference values for the power line....
