  • China ; Forecast ; Model ; Neural network ; Space time ; Spatial weighting ; Statistics ; Temperature ; Time series
  • The article presents a hybrid framework combining machine learning and statistical methods to address a modelisation of the nonlinearities and nonstationarities of environmental space-time series. A four-stage procedure is proposed and it is applied

  • Mobility ; Pedestrians ; Space time ; Spatial analysis ; Spatial choice ; Statistics ; Urban area
  • The AA. propose an exploratory statistical approach to detect patterns of movement suspension using a local indicator of spatial association in a vector space representation. Two data sets are used to evaluate the approach in terms of exploring

  • A GIS-based comparative study of frequency ratio, analytical hierarchy process, bivariate statistics and logistics regression methods for landslide susceptibility mapping in Trabzon, NE Turkey
  • Comparative study ; Geographical information system ; Inventory ; Landslide ; Methodology ; Natural hazards ; Statistical analysis ; Thematic mapping ; Turkey ; Vulnerability
  • The aim of this study was to evaluate the susceptibility of the occurrence of landslides in Trabzon province, situated in north east Turkey. This was achieved using the following 5 methods : the frequency ratio model, AHP, the statistical index (Wi

  • Arid area ; Erodibility ; Grain size distribution ; Land use ; Semi-arid area ; Soil erosion ; Soil properties ; Southern Tunisia ; Statistical distribution ; Tunisia ; Wind erosion
  • This paper analyses the statistical parameters of the grain size distributions of soils of South Tunisia where different landscapes coexist, with a graduation from semi-arid to arid and including both natural surfaces and agricultural or pastoral
  • areas. Two different methods were used : the logarithmic method of moments and the use of a combination of log-normal statistical functions. Both methods underline the ubiquitous and dominant presence of a very fine sand population, very well sorted

  • in 2 limestones from Spain. The Fraga and Tudela limestones are from the Ebro basin and are of Miocene age. Permeability mapping and statistical analysis before and after salt accumulation are used to assess changes in the spatial variability
  • of permeability and to correlate these changes with salt movement, porosity change, potential rock deterioration and textural characteristics. Statistical analyses of small-scale permeability measurements are used to evaluate the drivers for decay and hence aid

  • Permafrost is present at multiple elevations with no defined lower limit in the southern Yukon Territory, Canada. Empirical statistical modelling of permafrost probability in the region required the development of equivalent elevation, a new
  • temperatures at nearby climate stations, which permits prediction of equivalent elevation for the entire region. Permafrost probability modelling using equivalent elevation produced statistically significant results in several study areas.
