This study, with the help of minimum temperature data, has addressed the prediction of frost during 21 years period by means of neural network in Kermanshah province. In order to forecast frost, data were converted to the values between 0 and 1 by means of a subjective and one to one (injective) function. We have used feed-forward neural network by one hidden interior layer with number of chang...
Tea trees are the main economic crop in Zhejiang Province. However, spring cold is a frequent occurrence there, causing frost damage to valuable tea buds. To address this, regional frost-hazard early-warning system needed. In this study, area was estimated based on topography and meteorology, as well longitude latitude. Based support vector machine (SVM) artificial neural networks (ANNs), multi...
Recently, a western white pine protein, Pin m III, was shown to be associated with overwintering and frost hardiness of western white pine foliage. To examine whether Pin m III is directly involved in frost hardiness by functioning as an antifreeze protein, work is underway to clone the gene encoding this protein and to assess the function of this gene in freezing tolerance by incorporating the...
Under the background of intensifying global change, frequent occurrence agrometeorological disasters has an adverse impact on social economy. Low-temperature weather in spring is one main Xinjiang. Studying spatial and temporal characteristics low temperatures Xinjiang great significance. However, research spatiotemporal variation frost arid areas currently lacking, which limits our understandi...
