Remote sensing image fusion can effectively solve the inherent contradiction between spatial resolution and spectral of imaging systems. At present, methods remote images based on multi-scale transform usually set rules according to local feature information pulse-coupled neural network (PCNN), but there are problems such as single feature, rule cannot extract information, PCNN parameter settin...

In formal language theory, two very different models sometimes turn out to describe the same class of languages. This usually shows that there is a fundamental concept described by those models. A well-known example is the class of regular languages, which can be characterized by logic (monadic second order (MSO) logic), algebra (syntactic monoids), and many computational models (automata). In ...

The Prairie Pothole Region (PPR) of North America produces about half of the continent's duck population. Predation on hens, young, and eggs severely impacts duck production In the region decreasing fall flights. Recent studies conducted in the region suggest that management efforts to increase duck production need to consider both habitat and predator effects. Research indicates that managing ...
