A display was devised for the purpose of studying the information afforded by kinetic optical occlusion (the progressive erasure and replacement of static elements within a display). A microcomputer generated a series of equally spaced light bars on a dark background. The first bar on the left was suddenly blanked and, after a pause of variable duration (an… (More)
Spatially-explicit harvest scheduling models optimize the spatiotemporal layout of forest management actions to best meet management objectives such as profit maximization, even flow of products, or wildlife habitat preservation while satisfying a variety of constraints. This investigation focuses on modeling maximum harvest opening size restrictions whose… (More)
Optimal parameter settings to improve the efficiency of solving harvest scheduling models with adjacency constraints were examined using Ilog's Cplex R 11.2 optimizer tuning tool. A total of 160 randomly generated hypothetical forests were created with either 50 or 100 stands and four age-class distributions. Mixed integer programming problems were… (More)
Thirty-five presentations were given at the Symposium on topics ranging from bio-fuels harvesting logistics to efficiently monitoring the impacts of climate change by speakers Similar as in the previous issue this section contains also two articles. Both articles in this section involve multi-objective management planning for forests. The first paper, by… (More)
It is argued that correspondence strength is a joint function of the relative activity of short-range and long-range processes and not solely a function of a single correspondence process, and this puts Ullman's interpretation of his results in doubt.
