In many pattern classification problems, an intelligent neural system is required which can learn the newly encountered but misclassified patterns incrementally, while keeping a good classification performance over the past patterns stored in the network. In the paper, an heuristic pattern correction scheme is proposed using adaptively trained generalized regression neural networks (GRNNs). The...

introduction: nowadays virtual colonoscopy has become a reliable and efficient method of detecting primary stages of colon cancer such as polyp detection. one of the most important and crucial stages of virtual colonoscopy is colon segmentation because an incorrect segmentation may lead to a misdiagnosis.  materials and methods: in this work, a hybrid method based on geometric deformable models...

Flood stress on crops severely constrains food production. From 2011 to 2018, a plot test was conducted investigate the effects of flooding duration and growth stage soybean plant height, number solid pods, 100-grain weight, yield, dry matter mass, their interannual variation. The results showed that indicators were significantly influenced by year, stage, interaction. Under same smallest mass ...

Activities of NAD(+)-dependent sorbitol dehydrogenase (SDH), sorbitol oxidase (SOX), sucrose synthase (SS), acid invertase (AI), and neutral invertase (NI) in 'Encore' peach (Prunus persica L.) fruits and developing shoot tips were assayed during the growing season to determine whether carbohydrate metabolizing enzymes could serve as indicators of sink strength. In fruit flesh, SS activity was ...

Not enough attention has been paid to the comparison in yield performance and N responsiveness between hybrid rice inbred using large number of new cultivars released after 2000 under machine transplanting. Field experiments were conducted 2017 2018; 48 widely planted included four groups, namely indica hybrids (IHs), japonica inbreds (JIs), indica-japonica (IJHs), (IIs) that transplanted by wi...

supplementary irrigation is a key factor in dryland production of lentil (lens culinaris medik.). in order to study the effects of supplementary irrigation on phenological and morphological characters of three lentil (lens culinaris medik.) cultivars, a trial carried out as split block based on randomized complete block design with three replications at research field of agricultural college, f...
