Spectral profiles, transformed divergence values, and feature space derived from Landsat Thematic Mapper (TM) data were used to analyze the ability of four false color composites to discriminate between different classes of salt-affected soils. To compare the spatial distribution of salt-affected soil classes, maps were generated for each false color...
Networks are a structure common to many disciplines. Research on
networks has taken different forms in domains such as graph theory, sociology,
vascular networks, small-world networks, geomorphology, ecology, evolution and
engineering. Networks may be modeled as non-spatial networks (unvalued
graphs), which contain only topological information, or as spatial networks (valued...
Real time delivery of products is the context of stochastic demands and multiple vehicles is a difficult problem as it requires the joint investigation of the problems in inventory control and vehicle routing. We model this problem in the framework of Average reward Reinforcement Learning (ARL) and present experimental results...
Oregon has 45 species of birds that nest in holes (cavities) in
rotting or dead trees (snags). But, though they are very valuable for
wildlife, many snags in urban areas are cut down
and removed for aesthetic reasons or because they
are considered a hazard. If you have some dead...
Bats play an important role in controlling insect populations. In North America, bats are the primary predators of night-flying insects. Some species of bats can capture several hundred insects an hour, including insect species that can devastate valuable plants or crops.
Intact core tetraether membrane lipids of marine planktonic Crenarchaeota were quantified in water column-suspended particulate matter obtained from four depth intervals (~70, 500, 1,000 and 1,500 m) at seven stations in the northwestern Arabian Sea to investigate the distribution of the organisms at various depths. Maximum concentrations generally occurred at...
