In an ongoing research, 24 cultivated and wild cultivars of barley were evaluated for morphological characteristics of grain, pollen, and stomata. Traits of interest included length, width, and area. Results of variance analysis showed that all samples were differed in traits of stomata, grain, and pollen at probability levels of 1 and 5%, suggesting remarkable genetic variation among studied s...

Mitral regurgitation (MR) severity is routinely assessed by Doppler color flow mapping, which is subject to technical and hemodynamic variables. Vena contracta width may be less influenced by hemodynamic variables and has previously been shown to correlate with angiographic estimates of MR severity. This study was performed to compare mitral vena contracta width by multiplane transesophageal ec...

This study presents statistical evaluation of the dot area and line width on thermally developed CtP flexo printing plates using image analysis software PerfectEye v4.03. The aim of the study was to determine whether the dot area and line width when different processing parameters are applied (different main exposure time and different number of rotations of developing drum during developing pr...

In this paper we address the following shape optimization problem: find planar domain of least area, among sets with prescribed constant width and inradius. literature, problem is ascribed to Bonnesen, who proposed it in [3]. present work, give a complete answer problem, providing an explicit characterization optimal for every choice These are particular Reuleaux polygons.

Normal human observers compared either the width, height or area of two simultaneously-presented shapes (the standard and the test), with a cue to indicate which decision had to be made. On 'area' trials, test width was a random variable, ensuring that neither shape (aspect ratio), width nor height by themselves was a reliable signal. Weber fractions for width and height of both ellipses and re...

abstract- the evaluation of leaf area and leaf nutritional value is important for crop growth modeling and estimations of its performance. the purpose of this study was to use image processing techniques to develop an economical method to ease the assessment of nutrient status and leaf area (la) of plants and to compare the outcomes of this method with linear models. leaf area and leaf chloroph...

introdouction: the aim of the present study was to investigate image magnification in digital panoramic radiography and assess the effect of anatomical sites on the magnification in both males and females. materials and methods: in this retrospective study, digital panoramic radiographs of 48 patients with 202 implants were investigated. implant diameter and length were measured on panoramic ra...

dry drainage could be considered as a natural system which evaporates water from fallow areas to control water table depth and soil salinity in neighboring cropped area. the technique requires the retirement of part of the irrigated land. one of the most notable design criteria for this system is to estimate the ratio of cropped to fallow strip width. a plexiglas physical model with the dimensi...
