Approach: In order to find important associations, an appropriate support threshold has to be specified. The support threshold plays a key role in deciding the interesting itemsets. The rare … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 6,847 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Application of Ionic Liquids in Catholic Coupling of AcetophenonePo-Chung ChengProblem statement: The cathodic coupling of acetophnone was carried out in aqueous solutions containing sodium sulfate and 1-Octyl-3-Methylimidazolium Chloride ([OMIM]Cl) as supporting electrolytes. [OMIM]Cl is an ionic liquid, also serving as a co-solvent to prevent the deposition of products during electrolysis. The products are extracted with ether after electrolyses. Approach: It is shown in this study that the recycling of … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 7,043 accessesView PDFCite

Current methods for XML query processing still suffers from producing large intermediate results and are not efficient in supporting query with mixed types of relationships. We propose the TwigINLAB algorithm to process and optimize the query evaluation. Our TwigINLAB adopts the decomposition-matching-merging approach and focuses on optimizing … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 6,991 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Definition of Extended High-level Timed Petri NetsCheng Guangming, Liao Minghong, Wu XianghuMany extensions of Petri nets have been proposed to model the behaviors and time relations of embedded system, yet these models are all based on some assumptions about the behaviors of embedded systems. Especially they all do not have the actual ability to model interrupt mechanism of embedded system. A new net which is called Extended High Level Timed Petri … …Journal of Computer Science, Vol. 2, Issue 2 · 28 Feb 2006 · 7,042 accessesView PDFCite
