Optimal exploitation strategies for an animal population in a stochastic serially correlated environment Optimal exploitation strategies for an animal population in a stochastic serially correlated environment
Optimal exploitation strategies were studied for an animal population in a stochastic, serially correlated environment. This is a general case and encompasses a number of important cases as simplifications. Data on the mallard (Anas platyrhynchos) were used to explore the exploitation strategies and test several hypotheses because relatively much is known concerning the life history and...

Ground control requirements for precision processing of ERTS images Ground control requirements for precision processing of ERTS images
With the successful flight of the ERTS-1 satellite, orbital height images are available for precision processing into products such as 1:1,000,000-scale photomaps and enlargements up to 1:250,000 scale. In order to maintain positional error below 100 meters, control points for the precision processing must be carefully selected, clearly definitive on photos in both X and Y. Coordinates...
