the initial step in any breeding program including the breeding of walnut is an evaluation of the genetic diversity of its population and on identification of its superior and promising genotypes. this research was carried out during 2009-2010 growing seasons to evaluate the walnut genotypes, population grown in the vicinities of eghlid city, as one of the richest walnut population regions in t...

this study was carried out to investigate the important characteristics in some cultivars/genotypes of persianwalnut (juglans regia l.), black walnut (j. nigra l.), and walnut inter-specific hybrids: paradox (j. hindsii × j.regia) and royal (j. hindsii × j. nigra) in kamalshahr research station in karaj in 2011-2012. in the study,vegetative vigor was evaluated based on trunk cross-sectional are...

We present a new single-chip texture classifier based on the cellular neural network (CNN) architecture. Exploiting the dynamics of a locally interconnected 2D cell array of CNNs we have developed a theoretically new method for texture classification and segmentation. This technique differs from other convolution-based feature extraction methods since we utilize feedback convolution, and we use...

In thiswork, anewalgorithm isproposed for fast estimationofnonparametricmultivariate kernel density, based on principal direction divisive partitioning (PDDP) of the data space.The goal of the proposed algorithm is to use the finite support property of kernels for fast estimation of density. Compared to earlier approaches, this work explains the need of using boundaries (for partitioning the sp...

Juglans regia, commonly known as the Walnut tree, is a type of deciduous tree. The tree has many important parts, seed, bark, husk, leaves, oil, shell fruit and kernel. plant been used in its crude form since ages. kernel holds nutritional value. leaves contain an essential oil which extracted used. husk contains steroids vitamins amongst other useful compounds. are topically antipyretic, analg...

The microstructures of different groups of molluscs are characterized by preferential orientations of crystallites (texture), leading to a significant anisotropy of the physical properties of the shells. A complementary characteristic, usually neglected, is the distribution of the residual stresses existing within the shell wall. By means of X-ray diffraction, we study the distribution of stres...

The traditional gray level co-occurrence matrix (GLCM) is in two-dimensional form. Because hyperspectral imagery in the feature space has the characteristic of volumetric data, it has a great potential for three-dimensional texture analysis. Previous studies have successfully extended traditional 2D GLCM to a 3D form (Gray Level Co-occurrence Matrix for Volumetric Data, GLCMVD) for extracting f...
