  • A landslide susceptibility model using the analytical hierarchy process method and multivariate statistics in perialpine Slovenia
  • For the purpose of landslide susceptibility assessment the study area in the central Slovenia was divided to 78 365 slope units for which 24 statistical variables were calculated. For the land-use and vegetation data, multi-spectral high-resolution
  • images were merged using Principal Component Analysis method and classified with an unsupervised classification. Using multivariate statistical analysis (factor analysis), the interaction between factors and landslide distribution were tested

  • Geomorphology ; Hungary ; Loess ; Magnetic susceptibility ; Sedimentology ; Statistical analysis
  • The geological method, the AMS to be presented in this paper has been applied to solve the problem of the direction of transportation in sedimentology since 1960. The redeposited and the wind blown loess can be distinguished by statistical analysis

  • As a basic form of pattern analysis, the parameters of dune spacing, defect density, crest orientation and crest length are measured from remote images and treated statistically for dunes at White Sands in New Mexico, the Algodones in California

  • Demographic change ; Peripheral region ; Regional disparities ; Slovenia ; Statistical analysis ; Years 1960-69 ; Years 1990-99
  • Considering its small territorial and population size, Slovenia nevertheless has a considerable geographic, economic and social variety. Not surprisingly, there are significant regional disparities. A resarch study analysed statistical data

  • We determined changes in the settled areas of rural settlements by means of aerial photos and orthophotos, statistical data, and data obtained through field research. The expert sample comprised 14 rural settlements with 500 to 1100 inhabitants from
  • a variety of Slovene natural and statistical regions which in the past ten-year period have shown positive growth in the number of inhabitants, jobs, and houses. We identified how the following categories changed in settled areas in the period from 1991
