Characterizing the Statistical Properties of SAR Clutter by Using an Empirical Distribution
International Journal of Antennas and Propagation, Volume 2013, Issue 1, 2013., 2013 The performances on the applications of synthetic aperture radar (SAR) data strongly depend on the statistical characteristics of the pixel amplitudes or intensities. In this paper, a new empirical model, called simply āš¢o, has been proposed to characterize the statistical properties of SAR clutter data over the wide range of homogeneous, heterogeneous,

New Flexible Regression Models Generated by Gamma Random Variables with Censored Data [PDF]
, 2016 We propose and study a new log-gamma Weibull regression model. We obtain explicit expressions for the raw and incomplete moments, quantile and generating functions and mean deviations of the log-gamma Weibull distribution.

A Note on Fractional Order Derivatives and Table of Fractional Derivatives of Some Special Functions
Abstract and Applied Analysis, Volume 2013, Issue 1, 2013., 2013 The purpose of this note is to present the different fractional order derivatives definition that are commonly used in the literature on one hand and to present a table of fractional order derivatives of some functions in RiemannāLiouville sense On other the hand. We present some advantages and disadvantages of these fractional derivatives. And finally

On some combinatorial identities and harmonic sums
, 2017 For any $m,n\in\mathbb{N}$ we first give new proofs for the following well known combinatorial identities \begin{equation*} S_n(m)=\sum\limits_{k=1}^n\binom{n}{k}\frac{(-1)^{k-1}}{k^m}=\sum\limits_{n\geq r_1\geq r_2\geq...\geq r_m\geq 1}\frac{1}{r_1r_2 ...
