abstract- this study aims to model optimal cultivation pattern based on the maximization of importing virtual water and social net income of major crops in marvdasht, iran. for this purpose, a linear programming model was developed considering constraints of virtual water and land limitations followed by other models to include employment restrictions. based on the findings, wheat and tomato we...

In information extraction systems, pattern marchers are widely used to identi~q infof mat|on of interest in a scntcncc. In this paper, pattern matching in the Tt:XTRACT information extraction system is described. It comprises a conccpt search which |dent|-tics key words representing a concept, and a template pattern search which identifies patterns of words and phrases. TI'JXTI~,A(;T using thc ...

Phase extraction pattern recognition is a special case of nonlinear matched filtering. The phase extraction procedure is executed on the input function's Fourier transform as well as on the filter function's Fourier transform, both of which are manipulated for correlation purposes. This novel process is examined theoretically, by computer simulations and laboratory experiments. The implementati...

Searching for patterns is one of the main goals in data mining. Patterns have important applications in many KDD domains like rule extraction or classiication. In this paper we present some methods of rule extraction by generalizing the existing approaches for the pattern problem. These methods, called partition of attribute values or grouping of attribute values, can be applied to decision tab...
