This paper presents a descending method to classify Boolean functions in 7 variables under the action of affine general linear group. The classification determines number classes, set orbits representatives and generator stabilizer each representative. consists iteration process $$RM(k, m)/RM(r-1, m)$$ from that RM(k, m)/RM(r, m). We namely obtain classifications RM(4, 7)/RM(2, 7) RM(7, 7)/RM(3...

Signature matching, which includes packet classification and content matching, is the most expensive operation of a signature-based network intrusion detection system (NIDS). In this paper, we present a technique to improve the performance of packet classification of Snort, a popular open-source NIDS, based on generating native code from Snort signatures. An obvious way to generate native code ...

this paper is devoted to compiling a site geology map for town of amiriyeh, from seismic macro-zonation point of view using geophysical methods of shallow seismic, down-hole seismic and resistivity surveys. in this map site geology has been classified based on shear wave velocity, according to the criteria for site geology classification offered in the iranian code of practice for seismic resis...

Tire text and geometry detection are used in scanning tires in order to identify the tire type and classify them according to a code printed on the sidewall which is called “DOT Code” then checking the treads whether they are defected or not based on the pattern periodicity of them. Classification is done based on applying some image processing and pattern recognition techniques on both treads ...
