Algorithm series (18) using astronomical method to calculate Shiber (lower)

the coefficient less than 0.0003 in the IAU1980 nutation theory, so there are only 63 items. Each cycle term includes the calculation of the sine coefficient (phase Huang) of the Motion (Δψ), calculates the (Δε) cosine coefficient (phase Wei Xiang coefficient) of the intersection nutation and the linear combination coefficients of the 5 basic angular distances (m, M, D, F, Ω) for calculating the angle of convergence. The formula for calculating 5 basic angular distances is: Angle (angular dist

MACD, BOLL, KDJ Three combination of precision grasp the trend and trading!

Look first, is the Bollinger bands 3 tracks, the other is the stock price movementFigure 1Stock prices, which operate between the upper and lower Bollinger bands. Precisely, this is illogical, not the first track, and then the stock price in accordance with the track movement. Because the track is changing at the same time as the stock price. However, the price fluctuation range is between the upper and lower tracks. So, if you go to 5, or 13, out of orbit

The relationship between cloud computing and distributed, parallel processing, and grid computing

Yunshan. "Cloud computing" (Cloud Computing) is the development of distributed processing (distributed Computing), parallel processing (Parallel Computing) and Grid computing (grid Computing), or the business implementation of these computer science concepts. Many companies in the multinational information technology industry, such as IBM, Yahoo and Google, are using cloud computing to sell their products and services. The term cloud computing may be borrowed from the "electronic cloud" in qu

from several kilometers to dozens of kilometers and can overlap with each other. Because NMDS/LMDS features higher bandwidth and two-way data transmission, it can provide a variety of broadband interactive data and multimedia services to overcome the bottleneck of the traditional local loop, it can meet users' increasing demands for high-speed data and image communication. Therefore, it is a powerful tool to solve the communication network access problem. 6. Wireless LAN Access Technology DBS s
