In this paper, we use dynamical systems to analyze stability of desynchronization algorithms at equilibrium. We start by illustrating the equilibrium of a dynamic systems and formalizing force components and time phases. Then, we use Linear Approximation to obtain Jaconian (J) matrixes which are used to find the eigenvalues. Next, we employ the Hirst and Macey theorem [1] and Gershgorins theore...

In this paper, we present a new speech perceptual hashing authentication algorithm based on wavelet packet decomposition (WPD) for speech content authentication. Firstly, a wavelet packet coefficients matrix of wavelet reconstruction is generated from an original speech signal after high frequency pre-processing followed by wavelet packet decomposition. Secondly, the wavelet packet coefficients...

In this paper, an image-based method-non-uniform light field mapping is proposed which combines edge-based surface light field partition and non-uniform decomposition of light field matrixes for real-time rendering. Through this method view-dependent appearance of scenes with complex reflectance properties can be rendered in real-time. This method obtains surface light field by resampling the d...

BACKGROUND Real-time PCR is the technique of choice for nucleic acid quantification. In the field of detection of genetically modified organisms (GMOs) quantification of biotech products may be required to fulfil legislative requirements. However, successful quantification depends crucially on the quality of the sample DNA analyzed. Methods for GMO detection are generally validated on certified...

To provide an objective measure of the correlation between the internal energy content of ions generated by matrix-assisted laser desorption/ionization (MALDI) and the matrix properties, a series of well-characterized benzyl-substituted benzylpyridinium salts were used as thermometer molecules (TMs). To determine the internal energy variations of analyte ions, the survival yields of TM molecula...

A generic noncovalent approach for dispersing high concentrations of individual single-walled carbon nanotubes (SWNT) in organic as well as aqueous solutions of synthetic block copolymers is presented. It is suggested that a weak, long-ranged entropic repulsion among polymer-decorated tubes acts as a barrier that prevents the tubes from approaching the attractive part of the intertube potential...

Results are presented from an NMKL (Nordic Committee on Food Analysis) collaborative study of a method for the determination of cholecalciferol (vitamin D3) in foods. The method is based on the addition of an internal standard (vitamin D2), followed by saponification and extraction with n-heptane. The fraction that contains vitamin D2/D3 is separated by preparative normal-phase liquid chromatog...

The paper considers studying influence of a human-oriented info-imprinting on a work function of carriers of the imprinted information – metallic matrixes. The matrix-imprinted information proved its efficiency in a reduction of a thermal impact of a radiation of mobile phones, to which the matrixes were attached. Seebeck effect and Kelvin Probe installations were used and modified for the rese...

An easy to apply multi-criteria technique is the Matrixes Of Weighing (MOW), but many of the professionals that use it, in their respective fields, do it in intuitive fashion. In this regard, applications are rarely reported in specialized literature, which explains how few references exist about them. One of the application areas for MOW is the handling of catastrophes, in particular the pre-c...

in this paper, a stochastic cell formation problem is studied using queuing theory framework and considering reliability. since cell formation problem is np-hard, two algorithms based on genetic and modified particle swarm optimization (mpso) algorithms are developed to solve the problem. for generating initial solutions in these algorithms, a new heuristic method is developed, which always cre...
