physical characteristics of agricultural products are the most needed parameters in the design of grading, handling, processing and packing systems. among physical characteristics; dimensions, mass, volume, projected area as well as surface area are the important factors in sizing systems. for an assessment of morphological and physical characters in walnut, four genotypes of sizable kernels, l...

For the unitary ensembles of N × N Hermitian matrices associated with a weight function w there is a kernel, expressible in terms of the polynomials orthogonal with respect to the weight function, which plays an important role. For example the n-point correlation function and the spacing probabilities have nice representations in terms of this kernel. For the orthogonal and symplectic ensembles...

Purpose. Identification of spring barley promising breeding lines with combination adaptive traits under conditions the central part Ukrainian Forest-Steppe. Methods. Field trial, laboratory-field analysis drought tolerance, statistical and graphical experimental data. Results. The variance AMMI model showed that largest contribution to general variation (85.78%) had environmental (years resear...

In this paper, a model is proposed for the kernel in the generalized mixing rule recently formulated by Anderssen and Mead (1998). In order to derive such a model, it is necessary to take account of the rheological significance of the kernel in terms of the relaxation behaviour of the individual polymers involved. This leads naturally to consider a way how additional physical effects, which dep...

THIS PAPER DERIVES CONDITIONS for the consistency of kernel estimators of the covariance matrix of a weighted sum of vectors of dependent heterogeneous random variables. This is a problem that has been studied recently by, among others, Newey and West Ž . Ž . Ž . Ž . 1987 , Gallant and White 1988 , Andrews 1991 , Potscher and Prucha 1991b , An̈ Ž . Ž . drews and Monahan 1992 , and Hansen 1992 . ...

Wheat (Triticum aestivum L.) is one of the most successful domesticated plant species in the world. The majority of wheat carries mutations in the Puroindoline genes that result in a hard kernel phenotype. An evolutionary explanation, or selective advantage, for the spread and persistence of these hard kernel mutations has yet to be established. Here, we demonstrate that the house mouse (Mus mu...

In the spring of 1916, Prof. H.D. Hughes, of the Iowa Experiment Station, asked a number of experienced corn judges to score some five hundred ears of corn on the basis of what they thought the relative yields would be. These five hundred ears of corn were field run, varying from only three or four inches in length to more than ten inches. The variety was the college strain of Reid. In addition...

The k-nearest neighbors (knn) is a simple but effective method of classification. In this paper we present an extended version of this technique for chemical compounds used in High Throughput Screening, where the distances of the nearest neighbors can be taken into account. Our algorithm uses kernel weight functions as guidance for the process of defining activity in screening data. Proposed ke...

Barley (Hordeum vulgare L.) is the preferred crop in arid regions, particularly for farmers with limited agricultural resources and low income. Typically, it utilized human consumption, animal feed, malting. The discovery of natural (organic) sources biostimulants has attracted a great deal interest productivity enhancement. Using randomized complete block design three main blocks, was our aim ...
