introduction: ground water as a dynamic and recyclable natural resource in fractured rock terrains are characterized by single and double fracture porosity models. due to the heterogeneous nature of the medium hydraulic properties of these rocks are mainly controlled by fracturing and influenced by multivariate parameters. this heterogeneity is due to various compactions , density of fractures ...

This study describes crash causes, conditions, and distribution of accident hot spots along with an analysis the risk factors that significantly affect severity levels crashes their effects on pedestrian safety using machine learning (ML) techniques. Supervised ML algorithm–random forest decision tree–based algorithm-AdaBoost algorithms are applied compared to predict level future based road el...

‘Orchard meadows’ refers to the combination of extensively managed fruit trees in with fields and pastures. In many regions, among others Germany, Austria Switzerland, they are a landscape-defining element particular ecological, economic social importance. However, numbers orchard meadows have been decreasing for quite some time. Current detailed data that allow identification suitable coun...

A yield estimation method by remote sensing was used to estimate the yield of winter wheat in Jiangsu province, China. The first step of this study was to extract the planting area of winter wheat from environmental satellite images and land -use map of Jiangsu province, meanwhile, correlation analyses were performed by using 8-day of composite Leaf Area Index (LAI) data from Moderate Resolutio...
