Genetic divergence in 105 genotypes of toria Germ plasm was evaluated by using Mahalanobis's D2 test. Oil content, fatty acid composition and glucosinolate content was estimated and data obtained for various characters were subjected to statistical analysis i.e. analysis of variance, heritability, genetic advance, correlation and measurement of genetic divergence. Analysis of variance indicated...

به طور کلی مدل های پیوند در تحلیل داده های رسته ای در جدول های پیشایندی، به دو گروه مدل های ضربی و غیر ضربی تقسیم می شوند که با وجود اختلاف ذاتی که این مدل-ها با یکدیگر دارند،بعضی از آنها به بعضی دیگر نزدیک هستند. این ملاک نزدیکی را می توان با انواع فاصله ای متریک مناسب سنجید. ما در این پایانامه از معیار اطلاع divergence-?? که فاصله کولبک لیبلر را به عناون یک حالت خاص در بر دارد، برای تعیین مدل...

The fitness consequences of inbreeding and outbreeding have intrigued biologists for a long time. Recently a measure of relatedness of parental haplotypes has been proposed called mean d(2). This measure is based on a stepwise mutational process and therefore is tailored to microsatellite genetic markers. Theoretical work suggests that mean d(2) typically is less suited for measuring fitness co...

In recent times, intuitionistic fuzzy sets introduced by Atanassov has been one of the most powerful and flexible approaches for dealing with complex and uncertain situations of real world. In particular, the concept of divergence between intuitionistic fuzzy sets is important since it has applications in various areas such as image segmentation, decision making, medical diagnosis, pattern reco...

Studies on the evolutionary history of ascomycetes in terms of time scale will help to understand historical patterns that shape their biodiversity. Until now most of dating studies of ascomycetes have focused on major events in fungal evolution but not on divergence events within smaller groups of fungi e.g. within Sordariomycetes. We used molecular dating to estimate the time of separation of...

We apply a recently developed time-dependent Poisson random field model to aligned DNA sequences from two related biological species to estimate selection coefficients and divergence time. We use Markov chain Monte Carlo methods to estimate species divergence time and selection coefficients for each locus. The model assumes that the selective effects of non-synonymous mutations are normally dis...

Tin(II)-ion-selective electrode consisting of dibenzo-18-crown-6 (DB18C6) as an ionophore inPVC matrix was developed. The influences of membrane composition, selectivity, response time,reversibility and temperature on the electrode performance were investigated. The electrodeshowed a near Nernstian response for Sn2+ ions over a concentration range from 1.0× 10-6 – 1.0× 10-2 M with a slope of 27...

Motivated by the method of interpolating inequalities that makes use of the improved Jensen-type inequalities, in this paper we integrate this approach with the well known Zipf-Mandelbrot law applied to various types of f-divergences and distances, such are Kullback-Leibler divergence, Hellinger distance, Bhattacharyya distance (via coefficient), [Formula: see text]-divergence, total variation ...

The divergence criterion has been shown to be helpful in distinguishing between suband supercritical Hopf bifurcations but its applicability is limited to systems whose divergence is sign definite. A step by step computational procedure which allows one to extend the applicability of the divergence criterion is derived by altering the system to an equivalent one with sign definite divergence. T...
