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...
We introduce geometric comparison inequalities that give bounds on the eigenvalues of a reversible Markov chain in terms of the eigenvalues of a second chain. The bounds are applied to get sharp resul...
Comparison of peak and RMS gains for discrete-time systems
Discrete time system the peak more income signal function
2015/8/13
A convolution system can have a frequency response which is small for all frequencies, yet still greatly amplify the peaks of signals passing through it. For finite-dimensional systems, the authors es...
COMPARISON THEOREMS FOR REVERSIBLE MARKOV CHAINS
Geometry inequality reversible markov chain the characteristic value
2015/7/14
We introduce geometric comparison inequalities that give bounds on
the eigenvalues of a reversible Markov chain in terms of the eigenvalues
of a second chain. The bounds are applied to get sharp r...
COMPARISON OF PARSING TECHNIQUES FOR THE SYNTACTIC PATTERN RECOGNITION OF SIMPLE SHAPES
algorithms vision pattern recognition understanding
2015/6/2
Syntactic Pattern Recognition is a procedure, widely used in Cartography and Remote Sensing, that trusts upon matching of sections
of maps and/or images or 3D models with archetypes or objects (pars...
A Statistical Test on Capability of SNP Microarray Detecting CNVs: A Comparison to Sequence
Statistical Test Sequence
2014/12/5
Copy number variations (CNVs) are gains and losses of DNA se-quence of a genome, which result in the abnormality of the cell or
individual. The data from single nucleotide polymorphism (SNP)
microar...
VOLUME COMPARISON OF CONFORMALLY COMPACT MANIFOLDS WITH SCALAR CURVATURER≥ −n(n−1)
CONFORMALLY COMPACT MANIFOLDS called renormal-ized volume
2014/9/26
In this paper, we present a global invariant, called renormal-ized volume, which can be defined for a large class of conformally compact
manifolds. We use this definition to show a local volume compa...
Thermal modelling for endocardiac radiofrequency ablation: comparison of hyperbolic bioheat equation and Pennes bioheat equation with finite element method
Finite Element Method hyperbolic heat equation Pennes heat equation radiofrequency ablation theoretical model
2012/4/17
The objectives of this study are to model the endocardiac radiofrequency (RF) ablation procedure and to employ the Hyperbolic Bioheat Equation (HBE), which takes the thermal wave behaviour into accoun...
On the Comparison and Uniqueness for Solutions of BSDEs with Continuous Coefficients
Backward stochastic differential equation comparison theorem uniqueness
2011/11/5
As we known that there may be more than one solution for backward stochastic differential equation with continuous coefficients and the comparison theorem for any solutions of two BSDEs does not hold ...
Comparison principles for integro-differential equations with L{é}vy operators - the case of spacial depending jumps -
Integro-differential equation L´ evy-Ito Operator Compari-son principle
2011/1/21
A comparison principle for the integro-differential equation with the L´evy operator corresponding to the spacial depending jump process is presented in this paper. The jump (x, z) at a point x...
A generalization of Osgood's test and a comparison criterion for integral equations with noise
Osgood’s test comparison criterion time of explosion
2011/1/19
In this work, we prove a generalization of Osgood’s test for the ex-plosion of the solutions of initial-value problems. We also establish a comparison criterion for the solution of integral equations ...

Teichm¨uller space Teichm¨uller metric quasiconformal metric
2011/1/20
There are several Teichm¨uller spaces associated to a surface of infinite topological type, after the choice of a particular basepoint ( a complex or a hyperbolic structure on the surface). These spac...
