Comparison of Wavelet and FFT Based Single Channel Speech Signal Noise Reduction Techniques
DWT DWPT wavelet wavelet packet FFT noise control speech enhancement noise cancellation filter
2015/9/29
This paper compares wavelet and short time Fourier transform based techniques for single channel speechsignal noise reduction. Despite success of wavelet denoising of images, it has not yet been widel...
DESTRUCTION OF INVARIANT CURVES IN THE RESTRICTED CIRCULAR PLANAR THREE-BODY PROBLEM BY USING COMPARISON OF ACTION
INVARIANT CURVES RESTRICTED CIRCULAR PLANAR THREE-BODY PROBLEM
2015/9/25
The classical principle of least action says that orbits of mechanical systems extremize action; an important subclass are those orbits that minimize action. In this paper we utilize this principle al...
Average Minimum Transmit Power to achieve SINR Targets: Performance Comparison of Various User Selection Algorithms
Average Minimum Transmit Power SINR Targets Performance Comparison of Various User Selection Algorithms
2011/1/17
In multi-user communication from one base station (BS) to multiple users, the problem of minimizing the transmit power to achieve some target guaranteed performance (rates) at users has been well inve...
Comparison on modelling the relative risk estimation: Bayesian study
hierarchical Bayesian models relative risk potential scale reduction
2010/11/1
The estimation of the disease incidents was previously analyzed using a classical approach. However, this approach features large outlying relative risks and considered as misleading due to several ma...

A comparison of various influential points diagnostic methods and robust regression approaches: Reanalysis of interstitial lung disease data
robust regression methods local influence likelihood displacement
2010/9/25
In a linear regression model, the estimation of regression parameters by ordinary least squares method is affected by some anomalous points in the data set. Thus, detection of these abnormal points is...
Comparison of Spearman's rho and Kendall's tau in Normal and Contaminated Normal Models
Spearman's rho Kendall's tau in Normal Contaminated Normal Models
2010/11/15
This paper analyzes the performances of the Spearman's rho (SR) and Kendall's tau (KT) with respect to samples drawn from bivariate normal and bivariate contaminated normal populations. The exact ana...
Numerical solution to Belousov朲habotinskii model and a comparison with the finite difference method
Traveling wavelets method reaction- diffusion system
2010/9/10
In this work, we find a numerical solution to Belousov – Zhabontinskii system, we use the traveling wavelets method. It is well known that this model describes a chemical reaction. The results obtaine...
A comparison of the effect size estimators in meta-analysis
Meta-analysis effect size estimator fixed effects model
2010/9/13
The objective of a meta-analysis is usually to estimate the overall treatment effect and make inferences about the difference between the efffects of the two treatments. This article presents several ...
A Monte Carlo comparison between ridge and principal components regression methods
Multicollinearity ridge regression principal component regression
2010/9/15
A basic assumption concerned with general linear regression model is that there is no correlation (or no multicollinearity) between the explanatory variables. When this assumption is not satisfied, th...
