This paper presents a model to estimate the solar radiation under clear sky conditions over stationary, moving as well as flying objects. For the latter it is important to predict the peak solar irradiance under clear sky condition to calculate maxi
Largest prime factor Everybody knows any number can be combined by the prime number. Now, your task is telling me what position of the largest prime factor. The position of prime 2 is 1, prime 3 is 2, and prime 5 is 3, etc. Specially, LPF(1) = 0. Ea
量化交易多因子模型。A five-factor model directed at capturing the size, value, profitability, and investment patterns in average stock returns performs better than the three-factor model of Fama and French (FF, 1993). The five-factor model's main problem is it
In the last post we performed several steps in downloading and analyzing the fund performance data. We used the Fama French’s 3 factor model to analyze Fidelity Contrafund Fund (FCNTX). In this post we will repeat the same steps without all the expla
Based on the theory of semiconductor laser pattern and the non-paraxial vectorial moment theory of light beam propagation, the beam quality factor M^(2) of TE_(0) propagating mode is analyzed and calculated. The result shows that when both core layer
