KavithaA data warehouse is a collection of data gathered and organized so that it can easily be analyzed, extracted, synthesized and also be used for the purpose of further understanding data. Peer to Peer networks are used for distribution and sharing of documents. In traditional techniques, when aggregate functions like average, sum and count are encountered, the aggregate operation is … …Journal of Computer Science, Vol. 10, Issue 7 · 18 Feb 2014 · 6,908 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEffects of Environmental Noises on Fundamental Frequency Contours of Thai Expressive SpeechSuphattharachai Chomphan, Chutarat ChompunthProblem statement: The expressive speech of Thai had been studied for a short period of time. An important feature of speech was fundamental frequency (F0) which defines the human speech prosody. It could be used to distinguish the difference between several types of expressive speech. The environmental noises affect the F0 contour for Thai dialects as concluded in the previous … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 28 Jun 2012 · 6,907 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordIntubation using the Video LaryngoscopeBen H. Boedeker, W. Bosseau Murray, Thomas A. NicholasProblem statement: Inadequate airway management is a major contributor to morbidity and mortality in the prehospital and out-of-operating room hospital settings. Difficulties that occur during airway management are usually related to the intubator not being able to achieve an adequate view of the glottic opening to allow insertion of an endotracheal tube. Approach: Obtaining an adequate glottic view is technically … …Current Research in Medicine, Vol. 3, Issue 2 · 3 Apr 2012 · 7,527 accessesView PDF Cite
