‎The first variable Zagreb index of graph $G$ is defined as‎ ‎begin{eqnarray*}‎ ‎M_{1,lambda}(G)=sum_{vin V(G)}d(v)^{2lambda}‎, ‎end{eqnarray*}‎ ‎where $lambda$ is a real number and $d(v)$ is the degree of‎ ‎vertex $v$‎. ‎In this paper‎, ‎some upper and lower bounds for the distribution function and expected value of this index in random increasing trees (rec...

Since the publication of the Cooley-Tukey algorithm a variety of related algorithms for fast Fourier transforms have been suggested by Gentleman/Sande, Stockham, Pease, Johnson/Burrus and others. These algorithms diier mainly in the way they store and access their data. From a numerical point of view, they use splitting which is related to a factorization of the complex Fourier transform matrix...

Using the integrable nonlinear Schrödinger equation (NLSE) as a channel model, we describe the application of nonlinear spectral management for effective mitigation of all nonlinear distortions induced by the fiber Kerr effect. Our approach is a modification and substantial development of the so-called "eigenvalue communication" idea first presented in A. Hasegawa, T. Nyu, J. Lightwave Technol....

Acoustic noise canceller (ANC) is currently the technology emergent in the field of communications system. However quality of voice communications is one of the major aspects of communications system due to the concurrence in this field. In this paper we designed, developed and implemented on a fixed point DSP C6713 of a low cost adaptive acoustic noise canceller for improving the quality of th...

This paper presents a variant of the Discrete Fourier Transform (DFT) that is particularly destined for the implementation in embedded applications, which are characterized by limited resources in terms of memory and computing speed. Often these applications are highly specialized and require therefore an optimal relationship between costs and performance. It surely is of great interest to disp...

Objective The main purpose of this article is to choose the best predictive model for IVF/ICSI classification and to calculate the probability of IVF/ICSI success for each couple using Artificial intelligence. Also, we aimed to find the most effective factors for prediction of ART success in infertile couples. MaterialsAndMethods In this cross-sectional study, the data of 486 patients are colle...

Abstract Analysis of the dynamic response a complex nonlinear system is always difficult problem. By using Volterra functional series to describe system, its analysis can be similar Fourier/Laplace transform and linear transfer function method analyse system's response. In this paper, for systems based on developed. Firstly, recursive formula least square established solve kernel vector, corres...
