Dyno Articles

First off I am not asking how a dyno works. I am not trying to be rude but we all know that if this were the question this post would last for a month and someone woulkd flame someone else and blah blah blah.....

So, all I am asking is if anyone knows of any good articles/ sources on the web concerning dynomometers and emissions testing? Stuff I can use in a scholarly paper. Citing Automotive Forums doesn't quite cut it.

Thanks
