Estimating the parameters of K-distribution using higher-order and fractional moments [PDF]

, 1999
We propose a method for estimating the parameters of the K- distribution on a manner which significantly reduces computational requirements when compared with existing approaches. additionaly, the method yields paramter estimates with lower variance when

Digital particle image velocimetry measurements of the downwash distribution of a desert locust Schistocerca gregaria [PDF]

, 2006
Actuator disc models of insect flight are concerned solely with the rate of momentum transfer to the air that passes through the disc. These simple models assume that an even pressure is applied across the disc, resulting in a uniform downwash ...

Non-Dominated Sorting Genetic Algorithm II (NSGA2)-Based Parameter Optimization of the MSMGWB Model Used in Remote Infrared Sensing Prediction for Hot Combustion Gas Plume

Remote Sensing
The Multi-Scale Multi-Group Wide-Band (MSMGWB) model was used to calculate radiative transfer in strongly non-isothermal and inhomogeneous media such as the remote infrared sensing of aircraft exhaust system and jet plume scenario.

Modeling of Compound Gaussian Sea Clutter Based on Inverse Gaussian Distribution

Leida xuebao, 2013
The Compound-Gaussian (CG) distribution is widely used for modeling the non-Gaussian clutter, and its texture component describes the non-Gaussian properties of clutter. In this paper, a CG model with an inverse Gaussian texture distribution is proposed,

Limit Theorems for Lower-Upper Extreme Values from Two-Dimensional Distribution Function [PDF]

The Egyptian Statistical Journal, 1988
The limiting distribution of the random vector(V̅_(k,k^':n) - b̅_n) / a̅_n = (X_(1,k:n) - b₁ₙ) / a₁ₙ, (X_(2,n-k^'+1:n) - b₂ₙ) / a₂ₙ k and k' being constants, are investigated, necessary and sufficient conditions for waking convergence of the distribution

Generalized Hypergeometric Factorial Moment Distribution of Order k

, 2000
Here we introduce the generalized hypergeometric functional moment distribution of order k (GHFMD (k)) in the distribution of the random sum [Formula: see text] having Hira no's k-point distribution, where N, independent of X j's, has the generalized ...

Factorial moments of the Poisson distribution of order $k$ [PDF]

, 2023
The factorial moments of the standard Poisson distribution are well known. The present note presents an explicit combinatorial sum for the factorial moments of the Poisson distribution of order $k$. Unlike the standard Poisson distribution (the case $k=1$
