this experiment was conducted to investigate and evaluate the phenotypic and genotypic diversity of a population including of 94 doubled-haploids lines, their parents and five iranian local bread wheat (triticum aestivum l.) cultivars. thirteen agronomic and morphologic traits were recorded including; grain yield per unit area, harvest index, spike length, seed number per spike, spikelet densit...

The boundaries of oral lesions in color images were detected using a live-wire method and compared to expert delineations. Multiple cost terms were analyzed for their inclusion in the final total cost function including color gradient magnitude, color gradient direction, Canny edge detection, and Laplacian zero crossing. The gradient magnitude and direction cost terms were implemented so that t...

Cashmere is only produced from Maraz (Kurdi) goat breed in Iraqi Kurdistan Region. The objective of this study was to assess the genetic diversity of different Maraz color types, black goat and Shami breeds using random amplified polymorphic DNA (RAPD) markers. Fourteen primers were used and nine out of them were selected based on their number of bands (NB) and polymorphic characteristics. Thes...

Areca nut, commonly known locally as Semen Arecae (SA) in China, has been used as an important Chinese herbal medicine for thousands of years. The raw SA (RAW) is commonly processed by stir-baking to yellow (SBY), stir-baking to dark brown (SBD), and stir-baking to carbon dark (SBC) for different clinical uses. In our present investigation, intelligent sensory technologies consisting of compute...

to study breeding resource of kabuli chickpea lines of national plant gene bank of iran, two separate experiments were conducted during 2010 and 2011. in this study, 57 lines of kabuli type chickpeas- selected from primary evaluation experiments, out of 1500 accessions were planted at farm of seed and plant improvement research institute in karaj, iran, according a randomized complete block des...

A type of representation of the spectral bidirectional reflectance distribution function (BRDF) is proposed that distinctly separates the spectral variable (wavelength) from the geometrical variables (spherical coordinates of the irradiation and viewing directions). Principal components analysis (PCA) is used in order to decompose the spectral BRDF in decorrelated spectral components, and the w...

We develop an approach to utilize anisotropic metamaterials to solve one of the fundamental problems of modern plasmonics--parasitic scattering of surface waves into free-space modes, opening the road to truly two-dimensional plasmonic optics. We illustrate the developed formalism on the examples of plasmonic refractor and plasmonic crystal, and discuss limitations of the developed technique an...
