Landrum, J. L. (1989). Simplification methods for the World Vector Shoreline. Naval Ocean Research and Development Activity, NSTL Station, MS (USA).
Zusammenfassung: The fractal nature of the coastline makes it desirable to sample the World Vector Shoreline (WVS) data base in a manner related to the map scale at which it will be displayed. A survey of US Navy users has determined that several resolutions of the WVS are required. This report shows the relationship among vector data-base resolution, display device resolution, and map scale, then presents three simplification algorithms. These algorithms provide means of reducing the data-base resolution to that which is appropriate for a particular map scale and display device resolution. The discussion is supplemented with a series of maps illustrating the output of the simplification algorithms at several map scales.

Krivan, V., & Seda, J. (1989). Application of a guaranteed regression model to trophic interaction in an aquatic system (Vol. 49).
Zusammenfassung: The method of guaranteed estimation is used to estimate the unknown parameters of two nonlinear regression models. The first describes the relations between the body size structure of zooplankton and the biomass of planktivorous fish. The second estimates time-lag between the dynamics of cladoceran egg production and dynamics of phytoplankton.
