almond is one of the most valuable horticultural nut crops in the world with iran being amongst the most important regions of its distribution. rapd markers were employed to evaluate the diversity levels and relationship among some 56 collected genotypes of the crop. through sixteen rapd primers a number of, 171 dna bands were produced, 168 of which were polymorphic. the samples which according...

it is important to identify the genetic diversity and phylogenic relationships for achieving desirable citrus cultivars. in present investigation rapd markers were used to determine genetic diversity among 29 citrus genotypes. from 19 used primers, 248 polymorphic bands were amplified. primers opa-07 and opa-05 (with 19 and 8 amplified bands), produced maximum and minimum polymorphic bands, res...

In order to measure the similarity between two partitions coming from the same data set, we study extensions of the RV-coefficient, the kappa coefficient proposed by Cohen (in case of partitions with same number of classes), and the D2 coefficient proposed by Popping. We find that the RV coefficient is identical to the Janson and Vegelius index. We compare the result coming from kappa’s coeffic...

How to manage conflict is still an open issue in Dempster-Shafer evidence theory. The correlation coefficient can be used to measure the similarity of evidence in Dempster-Shafer evidence theory. However, existing correlation coefficients of belief functions have some shortcomings. In this paper, a new correlation coefficient is proposed with many desirable properties. One of its applications i...

There are two methods for GIS similarity measurement problem, one is cross-coefficient for GIS attribute similarity measurement, and the other is spatial autocorrelation that is based on spatial location. These methods can not calculate subzone similarity problem based on universal background. The rough measurement based on membership function solved this problem well. In this paper, we used ro...

A number of different markers (proteins, isoenzymes and RAPDs) have been used to settle taxonomic disputes and to assess genotype variability in populations of the genus Prosopis, in order to select highly productive phenotypes. In this study the genetic variability of two wild populations of Prosopis laevigata located in the Mexican states of Guanajuato (population 1) and Hidalgo (population 2...

Machine translation translates a speech of text from the source language to target language. This paper introduces machine translation evaluation by calculating the semantic textual similarity between the machine translated sentences. The similarity score varies by using different values of alpha, beta and ranges semantic similarity [0,5]. The experiment is carried out on SemEval 2017 datasets....

With the increasing influence of Business Process Management, large process model repositories emerged in enterprises and public administrations. Their effective utilization requires meaningful and efficient capabilities to search for models that go beyond text based search or folder navigation, e.g., by similarity. Existing measures for process model similarity are often not applicable for eff...

In this paper, a new method for solving classification problems based on prototypes is proposed. When using similarity relations for granulation of a universe, similarity classes are generated, and a prototype is constructed for each similarity class. Experimental results show that the proposed method has higher classification accuracy and a satisfactory reduction coefficient compared to other ...

The goal of the study was to determine which similarity coefficient and statistical method to use to produce the highest rate of correct assignment (RCA) in repetitive extragenic palindromic PCR-based bacterial source tracking. In addition, the use of standards for deciding whether to accept or reject source assignments was investigated. The use of curve-based coefficients Cosine Coefficient an...
