Markov Gamma Model
Gamma—Gamma模型是目前无线光通信中常用的光强闪烁模型。针对其参数模型较为复杂,各种近似模型 的使用无参考依据的问题,在高斯光束下,通过仿真计算的方法,分别研究了波形条件、孔径尺寸、传输距离、内外尺 度、湍流强度以及波长六方面因素对Gamma—Gamma模型的影响情况。结果表明:波形条件、孔径直径、传输距离、 ...

Phase measuring profilometry is a method of structured light illumination whose three-dimensional reconstructions are susceptible to error from nonunitary gamma in the associated optical devices. While the effects of this distortion diminish with an increasing number of employed phase-shifted patterns, gamm...

Particle-Antiparticle Mixing, epsilon_K, Delta Gamma_q, A_SL^q, A_CP(B_d -> psi K_S), A_CP(B_s -> psi phi) and B -> X_{s,d} gamma in the Littlest Higgs Model with T-Parity We present a number of correlations between the observables in question and study the implications...
Understanding the Gamma Pricing Model While theBlack-Scholesoption pricing model is the best known in the financial world, it does not actually provide accurate pricing results under all situations. In particular, the Black-Scholes model assumes that the underlying instrument has returns that are norm...
hydrologic time series in general, and stream-flow series, in particular, are dependent and not normally distributed, use of the classical autoregressive and moving average (ARMA) models to represent such series requires transformation of the original series into normal before applying the model.
