In this paper, the similarity solution of turbulent boundary layer flow on the flat plate with zero pressure gradients is presented. By employing similarity variables the governing partial differential equations are transformed to ordinary ones with inconsistent coefficients and solved numerically with the use of Runge–Kutta and shooting methods in conjunction with trial and error procedure. Fo...

Microarray time-series data provides us a possible means for identification of transcriptional regulation relationships among genes. Currently, the most widely used method in determining whether or not two genes have a potential regulatory relationship is to measure their expressional similarity using Pearson’s correlation coefficient. Although this traditional correlation method has been succe...

We use the finite lattice method to calculate the radius of gyration, the first and second area-weighted moments of self-avoiding polygons on the square lattice. The series have been calculated for polygons up to perimeter 82. Analysis of the series yields high accuracy estimates confirming theoretical predictions for the value of the size exponent, ν = 3/4, and certain universal amplitude comb...

A framework for the unification of statistical and structural information for pattern retrieval based on local feature sets is presented. We use local features constructed from coefficients of quantized block transforms borrowed from video compression which robustly preserving perceptual information under quantization. We then describe statistical information of patterns by histograms of the lo...

Measuring the similarity between documents is an essential task in Document Clustering. This paper presents a new metric that is based on the number and the category of the Named Entities shared between news documents. Three different feature-weighting functions and two standard similarity measures were used to evaluate the quality of the proposed measure in multilingual news clustering. The re...

in this study, the genetic diversity of 25 iranian saffron genotypes from three species (crocus speciosus, crocus cancellatus and crocus sativus) has been evaluated using 16 morphological traits and rapd marker. c. sativus was different with speciosus in the leaf number per plant, tepal length, flower weight, inflorescence stem height and the stigma length, but had no significant difference wit...

The capacity of a wireless network with fractal and hierarchical social communications is studied in this paper. Specifically, we mathematically formulate the self-similarity of a fractal wireless network by a power-law degree distribution P (k), and we capture the direct social connection feature between two nodes with degree k1 and k2 by a joint probability distribution P (k1, k2). Firstly, f...

Reflection of a shock from a solid wedge is a classical problem in gas dynamics. Depending on the parameters either a regular or a irregular (Mach-type) reflection results. We construct regular reflection as an exact self-similar solution for potential flow. For some upstream Mach numbers MI and isentropic coefficients γ, a solution exists for all wedge angles θ allowed by the sonic criterion. ...

A crucial dimension of Content-based music management systems is their ability to compute automatically similarities between music titles. We propose a technique that allows users to find music titles that sound similar to songs they like. The technique relies on a modelling of the timbral characteristics of a music signal by distributions of Cepstrum coefficients. The resulting models are then...

This article focuses on the importance of the precise calculation of similarity factors between papers and reviewers for performing a fair and accurate automatic assignment of reviewers to papers. It suggests that papers and reviewers’ competences should be described by taxonomy of keywords so that the implied hierarchical structure allows similarity measures to take into account not only the n...
