This doesn't read like an encyclopedia entry. The (home-made?) diagrams don't fit the Wikipedia style/format. The article is unnecessary unless it is to be annexed to the similar existing articles on this subject.
I put this article together from a PowerPoint presentation, since my ‘encyclopaedia’ entry was removed due to an accusation of plagiarism. I had copied it from a previous article I had written myself. [Guilty as charged but although I gave myself permission to use it, this was still not enough to resolve the issue] This article is meant to be a brief alternative introduction, which may be of benefit to the neophyte, rather than being aimed at those who are already knowledgeable in the subject. The diagrams are “home made” to avoid any further plagiarism dispute and I feel that they unfortunately need to be that size, since some of the original PowerPoint text would otherwise not be clear enough. 89.240.95.93 16:39, 24 December 2006 (UTC)
There are already articles on this subject, so this article should be merged with them or deleted. Since it was created from a presentation rather than being written as an encyclopedia entry, perhaps it would be better suited for Wikiversity.Nimrand 18:22, 27 June 2007 (UTC)
