Using Hybird Genetic Algorithm In Audio Steganography [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية, 2013
In this paper, a proposed method for hiding secret data in audio file (.WAV) is introduced. Genetic algorithm has been hybridized with conjugate gradient algorithm which is one of the methods for solving nonlinear unconstrained minimization problem, the ...

Channel Estimation for RIS-Aided mmWave MIMO Systems via Atomic Norm Minimization [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2020
A reconfigurable intelligent surface (RIS) can shape the radio propagation environment by virtue of changing the impinging electromagnetic waves towards any desired directions, thus, breaking the general Snell’s reflection law.

A Matrix-Field Weighted Mean-Square-Error Model for MIMO Transceiver Design [PDF]

open access: yesIEEE Communications Letters, 2013
We investigate the multiple-input multiple-output (MIMO) transceiver design using a weighted mean-square-error (MSE) minimization approach. A novel weighted MSE model is proposed, and it is defined as a linear matrix function with respect to the ...

Privacy in Quantum Estimation

open access: yesProceedings, 2019
We introduce the notion of privacy in quantum estimation by considering an one-parameter family of isometries taking one input into two output systems.

Plug-in Bandwidth Selection for Kernel Density Estimation with Discrete Data

open access: yesEconometrics, 2015
This paper proposes plug-in bandwidth selection for kernel density estimation with discrete data via minimization of mean summed square error. Simulation results show that the plug-in bandwidths perform well, relative to cross-validated bandwidths, in ...

A significant minimization of Pearson’s X2 statistics in 2x2 contingency tables: preliminary results for small samples

open access: yesEpidemiology, Biostatistics and Public Health, 2018
The Pearson’s chi-square test or X2 test represents a nonparametric test more used in Medicine, Biology and Social Sciences, but it introduces some error for 2x2 contingency tables, therefore Yates introduces a continuity correction.

Asymptotic Integrated Mean Square Error Using Least Squares and Bias Minimizing Splines

open access: yesThe Annals of Statistics, 1980
Let $S^d_k$ be the set of $d$th order splines on $\lbrack 0, 1 \rbrack$ having $k$ knots $\xi_1 < \xi_2 \cdots < \xi_k$. We consider the estimation of a sufficiently smooth response function $g$, using $n$ uncorrelated observations, by an element $s$ of $S^d_k$.

MRDPGA: a multiple restart dynamic population genetic algorithm for scheduling road traffic

open access: yesJournal of Electrical Systems and Information Technology, 2023
A genetic algorithm is a biologically inspired stochastic approach to finding solutions to optimization problems. However, unlike its deterministic counterpart, it cannot guarantee a globally optimal solution since it may be trapped within a local ...
