In this paper we consider the enumeration of binary trees avoiding non-contiguous binary tree patterns. We begin by computing closed formulas for the number of trees avoiding a single binary tree pattern with 4 or fewer leaves and compare these results to analogous work for contiguous tree patterns. Next, we give an explicit generating function that counts binary trees avoiding a single non-con...

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 ...

This paper brings out the design patterns according to the various services involved in internet banking. The Pattern oriented Software Architecture uses the pattern which eliminates the difficulty of reusability in a particular context. The patterns are to be designed using BPM (Business Process Model) for effective cross cutting on process level. For implementing the above said BPM, the Inter...

Abstract Artificial neural networks use a lot of coefficients that take great deal computing power for their adjustment, especially if deep learning are employed. However, there exist coefficients-free extremely fast indexing-based technologies work, instance, in Google search engines, genome sequencing, etc. The paper discusses the methods pattern recognition. It is shown recognition applicati...
