Talk:Process window index

Issues

Just minutes ago I found in this article a passage that read as follows:

---

${\text{PWI}}=100\times \max _{i=1\dots N \atop j=1\dots M}\left\{\left|{\frac {measured\_value_{[i,j]}-average\_limits_{[i,j]}}{range_{[i,j]}/2}}\right|\right\}$

Where:

i = 1 to N (number of thermocouples)

j = 1 to M (number of statistics per thermocouple)

measured_value [i,j] = the [i,j]^th statistic's value

average_limits [i,j] = the average of the [i,j]^th high and low limits of the statistic

range [i,j] = the [i,j]^th high limit minus the low limit of the statistic

---

I changed it to say this:

---

${\text{PWI}}=100\times \max _{i=1\dots N \atop j=1\dots M}\left\{\left|{\frac {{\text{measured value}}_{[i,j]}-{\text{average limits}}_{[i,j]}}{{\text{range}}_{[i,j]}/2}}\right|\right\}$

Where:

i = 1 to N (number of thermocouples)

j = 1 to M (number of statistics per thermocouple)

measured value [i, j] = the [i, j]^th statistic's value

average limits [i, j] = the average of the [i, j']^th high and low limits of the statistic

range [i, j] = the [i, j]^th high limit minus the low limit of the statistic

One lesson is that whatever it takes to get nominated to be a "Good Article", it doesn't required much attention to standard Wikipedia style conventions. Then I corrected two links in the opening section in which every word began with an incorrectly capitalized initial letter.

So now I'm wondering: why does every word in the title phrase begin with a capital letter? Michael Hardy (talk) 04:01, 26 December 2008 (UTC)

Hi Michael, thank you for the fixes and article review. The text was in capitals because I had initially thought these were proper nouns – at least in some of the books I have with me, they were. Now that you mention it, I did verify them, and have changed these to lower case. Regards, Zithan (talk) 15:06, 26 December 2008 (UTC)

Hello. When I said "the title phrase", I meant the phrase that is the title of the article: Process Window Index. Why do those three words have capital initial letters? Michael Hardy (talk) 18:22, 26 December 2008 (UTC)

Not sure. That's what the sources say. Zithan (talk) 18:37, 2 January 2009 (UTC)
