Angular Dependence of ${\cal K}$ -Distributed Sonar Data [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2007
Backscattered signal statistics are widely used for target detection and seafloor characterization. The K-distribution shows interesting properties for describing experimental backscattered intensity statistics. In addition to the fact that its probability distribution function accurately fits actual sonar data, it advantageously provides a physical ...

Optimal location of logistics distribution centres with swarm intelligent clustering algorithms.

open access: yesPLoS ONE, 2022
A clustering algorithm is a solution for grouping a set of objects and for distribution centre location problems. But the common K-means clustering algorithm may give local optimal solutions. Swarm intelligent algorithms simulate the social behaviours of

Bayesian estimation ofg-and-k distributions using MCMC [PDF]

open access: yesComputational Statistics, 2005
The generalized \(g\)-and-\(k\) distribution can be characterized by it's quantile function \[ Q(u)=A+B\left( 1+c{1-e^{-gz_u}\over 1+e^{-gz_u}} \right)z_u(1+z_u^2)^k, \] where \(A\) and \(B\) are location and scale parameters, \(g\in R\) is a measure of skewness, \(k>-0.5\) is a measure of kurtosis, \(c=0.8\), and \(z_u\) is the \(u\)-th quantile of ...

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

open access: yesRemote 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

open access: yesLeida 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]

open access: yesThe 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
