[edit] Orphaned fair use image (Image:Blackjack 2007.jpg)

I think that you are being a little overzealous here - maybe you should give me a few minutes before suddenly declaring something an orphaned image - as I was just in the process of editing the page on which I was going to place the image - I think that maybe you should at least wait for 24 hours before deciding something is an orphaned image Dan arndt 00:52, 20 February 2007 (UTC)

Sorry, just ran across it and didn't notice. Atropos235 00:54, 20 February 2007 (UTC)

[edit] your data

Here are examples of the kind of graphs I can make. Is this at all like what you want? On the left is a "clean" graph without grid lines on the body of the graph. On the right there are some grid lines. Which do you like? Please let me know if you have any other preferences and suggestions. I see values for pka on the spread sheet for lab 8. Can you explain where those values came from...did your software automatically estimate the location of the inflection points? For the final graphs, do you want the plots of the derivatives below the pH plots (as on the spread sheet for lab 7) or do you want the pH and derivative on one graph (as on the spread sheet for lab 8)? --JWSchmidt 05:00, 14 March 2007 (UTC)

Here is a version with two panels. I forgot to indicate that the lower panel is on a log scale. Please provide additional suggestions/corrections. --JWSchmidt 17:06, 14 March 2007 (UTC)

The necessary coefficients are given in Savitzky, A.; Goloy, M. J. E. (1964). "Smoothing and Differentiation of Data by Simplified Least Squares Procedures" Anal. Chem. 36:1527–39; along with the formal derivation. Unfortunately, I don't currently have access to a copy of this article :( The procedure is very easy to put in place once you have an Excel file of the data points.

The name sounds familiar, my univ. library might have a copy I can dig out. -- atropos235 ✄ (blah blah, my past) 18:04, 20 March 2007 (UTC)

[edit] Spring damper

Whoops. My bad. When I build up my tagging momentum, I sometimes miss image descriptions; I've re-tagged it as a 'diagram.' Thanks! MithrandirMageT 13:06, 8 April 2007 (UTC)
