Pattern recognition have been a topic of active research during the 30 years, due to the high performance that these schemes presents, when they have been used in the solution of many practical problems in several fields of science, medicine and engineering. The efficiency of pattern recognition algorithms strongly depends in an accurate features extraction scheme that be able to represent the ...

This paper presents an approach for the automated extraction of process patterns from Event-driven Process Chain (EPC) models in engineering domains. The manually extraction of process patterns (semantically described reference building blocks) is a labor-intensive, tedious and cumbersome task. The introduced approach comprises the three stages knowledge acquisition, process pattern extraction ...

In this paper, we discuss the performance of crosslingual information extraction systems employing an automatic pattern acquisition module. This module, which creates extraction patterns starting from a user’s narrative task description, allows rapid customization to new extraction tasks. We compare two approaches: (1) acquiring patterns in the source language, performing source language extrac...

the purpose of this study is to investigate the performance and efficiency of moringa seeds from different sources on turbidity. a protein analysis test was done for each source; then two different methods of extraction were compared to examine the coagulation activity for the moringa's active ingredient. the results of sodium chloride (naci) extraction in comparison to distilled water ext...

Amongst organophosphate pesticides, the one most widely used and common environmental contaminant is diazinon; thus methods for its trace analysis in environmental samples must be developed. Use of diazinon imprinted polymers such as sorbents in solid phase extraction, is a prominent and novel application area of molecular imprinted polymers. For diazinon extraction, high performance liquid chr...

The effects of different solvents, temperature conditions, solvent-solid ratios and particle sizes on solid-solvent extraction of the total phenolics, proanthocyanidins and flavonoids herein also referred to as antioxidant from pomegranate marc peel (PMP) was studied. Water, methanol, ethanol, acetone, and ethyl acetate extraction efficiencies at extraction times of 0.17 to 10 min, extraction t...

a rapid and reproducible method is described that employs solid phase extraction (spe) using dichloromethane, followed by gas chromatograph-mass spectrometry for the determination of toxic toluene, xylene and cumene (txc) from different lake water of dhaka mega city of bangladesh. the method was applied to detect and quantify txc in water samples collected from surface and 30 cm depth of water....

the purpose of this study, determining the optimal cultivation pattern by using interval mathematical programming approach among the farmers of esfarayen county before and after targeting the subsidies. for this purpose, farmers based on water resources classified in three group of using the river water, deep wells water and rainfed cultivation. the required data for this study has been obtaine...
