One of the designs of cellular manufacturing systems (CMS) requires that a machine population be partitioned into machine cells. Numerous methods are available for clustering machines into machine cells. One method involves using a similarity coefficient. Similarity coefficients between machines are not absolute, and they still need more attention from researchers. Although there are a number o...

This paper discusses some aspects of the general convergence behavior of genetic algorithms. Careful attention is given to how different selection strategies influence the progress of genetic diversity in populations. For being able to observe genetic diversity over time measures are introduced for estimating pairwise similarities as well as similarities among populations; these measures allow ...

Genetic variation of 16 white and yellow astragal accessions collected from three protected regions of Isfahan province (Mooteh, Kolah-Ghazi and Ghamishloo) were evaluated using ISSR marker. Nine ISSR primers produced 221 bands in which 204 were polymorphic among astragal accessions. ISSR banding patterns were transformed into binary data of presence–absence and matrices were processed with NTS...

BACKGROUND Research suggests that suicidal behaviour is aggregated in families. However, due to methodological limitations, including small sample sizes, the strength and pattern of this aggregation remains uncertain. METHOD We examined the familial clustering of completed suicide in a Swedish total population sample. We linked the Cause of Death and Multi-Generation Registers and compared su...

Dermatophytes are a group of keratinophilic fungi capable of invading keratinized tissues (skin, hair and nails). They cause dermatophytosis (commonly known as tinea or Ring worm) in human and animals. In this report, DNA similarities and genomic linkage of 40 dermatophytes strains was obtained from different universities, were studied by random amplified polymorphic DNA (RAPD–PCR) using 11 ra...

having knowledge about genetic relationships among accessions is necessary for developing breeding strategies to produce improved cultivars. in present study, genetic diversity and inter-relationship among 29 genotypes of citrus were comparatively analyzed using morphological and rapd markers. significant variability was observed among citrus genotypes for 61 quantitative and qualitative morpho...

in order to study the genetic diversity of the causal agent of fusarium wilting in chickpea, two techniques including rapd and pcr-rflp were used. in rapd-pcr technique, all 14 primers could show the diversity among the isolates. after studding the banding patterns of 14 primers, a dendrogram based on similarity matrix was constructed. the rapd dendrogram analysis could not separate isolates ba...

We define a genetic similarity rule that predicts how genetic variation in a dominant plant affects the structure of an arthropod community. This rule applies to hybridizing cottonwood species where plant genetic variation determines plant-animal interactions and structures a dependent community of leaf-modifying arthropods. Because the associated arthropod community is expected to respond to i...
