  • Mathematics and measurement.
  • Multiregional mathematical demography: themes and issues
  • Some mathematical models for permafrost
  • A review of fundamental new results in mathematical theory of geocryological problems obtained in the Institute of Mechanics in Moscow State University. The problems of temperature regime and phase state of permafrost, formation and evolution
  • of thermokarst are analyzed. In this paper the mathematical models of these problems, computer programs for the models and some numerical calculations for concrete objects and districts are suggested.
  • The study of complexity-some ideas from mathematical modelling in Climatological extremes in the mountains, Physical background, geomorphological and ecological consequences.
  • One of the simple lessons from mathematical modelling is that complex behaviour need not have a complex cause. The A. tries to demonstrate this point by elaborating on some of these novel mathematical ideas, described under the headings catastrophes
  • Spatial mathematical modeling and regional science
  • Expansion method ; Mathematics ; Modelling ; Regional science ; Spatial analysis
  • Choice of mathematical models in geographic research considering alternatives.
  • This Ph. D. thesis is a first attempt to explore the gap between mathematics and geography. The human geographer or social scientist usually speaks a different language than the mathematician. Concepts such as entropy, diffusion and allometry play
  • Ein mathematisches Okosystemmodell für eutrophe Flachgewässer. (A mathematical ecosystem model of eutrophic shallow lakes)
  • In order to allow forecasting and control of water quality, a mathematical ecosystem model has been set up for shallow lakes of Berlin.
  • Physical principles of climate mathematical modelling
  • Atmospheric circulation ; Climate ; Climatic variability ; Forecast ; Global change ; Human impact ; Mathematical model ; Model
  • In this paper the nature, state and variability of the climate system are described briefly. Of particular importance in open systems such as components of the climatic system is feedback. Mathematical models provide a new way to not only understand
  • Introduction to multistate mathematical demography in Essays in multistate mathematical demography| special IIASA issue.
  • A mathematical programming approach to elementary school facility decisions
  • Public sector projects in a mathematical modeling course
  • A mathematical model for scheduling screening tests for progressive diseases
  • Developments in mathematical programming models and their impact on the spatial allocation of educational resources
  • Cartographical display ; Correlation ; Mathematics ; Teaching of geography ; United States of America
  • This article explains how students can acquire a solid basis for building connections between mathematics and geography by studying correlations on maps and by making scatter diagrams. - (DWG)
  • A mathematical theory of migration. H. Hotelling (1895-1973)
  • Multistate demography and its data: a comment in Essays in multistate mathematical demography| special IIASA issue.
  • Eugenics and the rise of mathematical statistics in Britain in Demystifying social statistics.
  • A CO-climate sensitivity study with a mathematical model of the global climate
  • Distribution of points ; Mathematics ; Spatial analysis
  • Standard deviational ellipse is not at all an ellipse. The main focus of the paper is to clarify mathematically the actual shape of this curve and to discuss its applications in spatial analysis. This shape changes from a single circle to double
  • Mathematical partitioning of the receiver operating curve: a diagnostic tool for medical decision making
