Optimal Spacing of Soil Conservation Barriers

Soil Erosion and Conservation

Optimal arrival traffic spacing via dynamic programming∗

We present the application of dynamic programming to a combinatorial optimization problem to achieve proper arrival runway spacing, which appears in the process of assigning speed during the transition to approach and approach phases of flight. We apply the algorithm to data from a fast-time simulation developed under NASA’s Advanced Air Transportation Technologies Project for investigating new...

Optimal Wire Spacing Under Cross Talk Constraints

Risk spreading, connectivity, and optimal reserve spacing.

Two important processes determining the dynamics of spatially structured populations are dispersal and the spatial covariance of demographic fluctuations. Spatially explicit approaches to conservation, such as reserve networks, must consider the tension between these two processes and reach a balance between distances near enough to maintain connectivity, but far enough to benefit from risk spr...
