  • Bayesian smoothing of rates in small geographic areas
  • Mapping potential evapotranspiration: the smooth interpolation of isolines with a low density station network
  • A smooth ride ? From industrial to creative urbanism in Oshawa, Ontario
  • development. Planners and policymakers that mistake the complexities of economic restructuring for a smooth urban transition put the cities at risk of creating new problems out of efforts to improve local conditions.
  • Runoff and sediment losses from rough and smooth soil surfaces in a laboratory experiment
  • The aim of this study was to measure the effects of initial surface roughness on runoff and erosion under controlled laboratory conditions. Initially, rough and smooth surfaces were exposed to 5 simulated rainfall applications at 5% and 20% slopes
  • Problems associated with smoothing and filtering of geophysical time-series data
  • A synthesis of footloose-entrepeneur new economic geography models : when is agglomeration smooth and easily reversible ?
  • Effects of terrain smoothing on topographic shielding correction factors for cosmogenic nuclide-derived estimates of basin-averaged denudation rates
  • of the elevation data, and terrain smoothing has a potentially large effect on the correction of terrestrial cosmogenic nuclide production rates for skyline shielding. For rough, high-relief landscapes, the effect of terrain smoothing can easily exceed analytical
  • errors, and should be taken into account. Here the AA. demonstrate the effect of terrain smoothing on topographic shielding correction factors for various topographic settings, and introduce an empirical model for the estimation of topographic shielding
  • Smoothing regional maps using empirical Bayes predictors
  • Bayesian areal interpolation, estimation, and smoothing : an inferential approach for geographic information systems
  • Accuracy of an estuarine hydrodynamic model using smooth elements
  • Rough water, smooth water : a comprehensive classification of water-flow characteristics
  • Creation of smooth contours over irregularly distributed data using surface patches
  • Maps that falsify fall into the following categories : political propaganda, map errors, map generalization, map smoothing and enhancement, map simplification with falsification, and disinformation. - (DWG)

  • The work described here has sought to apply the exponential smoothing technique in the description of changes in mean annual air temperatures noted from Szczecin in the years 1949–2008, as well as to attempt to predict the feature in question over
  • the next decade. The starting point for the research was a time series for annual air temperature calculated from monthly values obtained from the meteorological station at Szczecin-Dąbie. The exponential smoothing method after Brown was applied, with use
  • therein made of both additive and multiplicative models, with a linear trend and an 8-year periodic component. It emerged that the exponential smoothing method is effective when it comes to predicting mean annual air temperature over the 60-year period
  • The two-dimensional smoothed power spectrum of the gravity field indicates that the cut-off frequency should be somewhere between 0.01 per km and 0.02 per km or the cut-off wavelength between 50 km and 100 km. Three examples from the set of regional
  • Mapping market areas using nonparametric smoothing
  • as the erosion of an initially smooth surface proceeds. A second approach uses a computational cellular method. The application of the cellular method to problems of geomorphological interest are discussed.
  • The A. suggests an approach for assessing the significance of peaks in the surface that result from the application of the smoothing kernel. The approach may also be thought of as a method for assessing the maximum among a set of suitably defined
