## Fair use rationale for File:Amc solo logo.svg

Thanks for uploading File:Amc solo logo.svg. You've indicated that the image meets Wikipedia's criteria for non-free content, but there is no explanation of why it meets those criteria. Please go to the image description page and edit it to include a fair use rationale. If you have any questions, please post them at Wikipedia:Media copyright questions.

Thank you for your cooperation. NOTE: once you correct this, please remove the tag from the image's page. STBotI (talk) 02:56, 31 December 2008 (UTC) free fall.com stupid — Preceding unsigned comment added by 206.131.59.154 (talk) 19:22, 11 February 2013 (UTC)

## belated answer to question you posted on fractional calculus

Multiple integration can be seen as measuring the volume of a solid, the area of a surface, the length of a curve, etc. By extension, fractional integration can be seen as measuring the volume/area/length/whatever of a fractal.

Note, 1st-order integration on a volume will give you a surface of lengths, 2nd-order will give you a curve of areas, and 3rd-order will give you a point of volume. The same holds true for fractional integration.

In a way, integrating over an R-dimensional region is just projecting an N-dimensional function onto an N-R dimensional space. think of shining light through a translucent (3D)object onto a (2D)piece of paper. the darkness at a point on the (2D)surface of the paper is equal to the (1D)thickness("length") of the object at that point. 2D+1D=3D The "region of integration" in this example are the (1D)rays cast through the object. (The rays accumulate opacity.) (Really opacity multiplies (50% opaque* 50% opaque = 25% penetration), but the principle is the same. And besides, you can just take the natural log of the darkness to convert it to a sum.)

Thus, for example, if you do a fractional integration on coral, of order equal to the fractal dimension of the coral, you might get some (0D)growth parameter such as the rate of calcium deposition.

Now if you integrate to a lower order you might get from that a "surface" of growth rates, or something like that (though it might not be a 2-dimensional "surface"). If you look at a point in a region not on the surface of the coral, you might very well get a growth rate that's "locally undefined" - which is all perfectly logical because there's no coral there.

You also might want to consider blowing up a fractal balloon. It a twist on the oft-cited related rates problem, and the solution is just about as straightforward. The important point is that the intuition is just as applicable, and most of nature's balloons are fractal.

You see, since nature has to follow the laws of mathematics and vice-versa, even very high-level math usually has very simple and intuitive explanations. Which is why visualizing the problems, mathematical operations, etc. can often make math MUCH easier than just using a purely formal/symbol approach. (And more useful.) Perhaps not too surprisingly, this was Benoit Mandlebrot's approach.

If I still haven't answered your question: "At what fractional does the fractional derivative does the non-smoothness make the fractional derivative locally undefined?" - then let me just say that it's the same as non-fractional integration. You're really not doing anything different, spatially speaking. And the formalism only describes what's going on spatially, so if you try to measure the volume of a surface or something like that, you'll have problems. Just so long as you realize what you're actually doing, there should be no surprises. And one more thing: notice that integration has a region of integration, but differentiation doesn't. That's why you have to add that "C"(integration constant) back in when you reverse it (and why the "C"'s on the other side of the equation). Same holds true for fractional integration, only the "C" might be a function of fractional dimension. (In a way, the "C" represents information lost in the projection.) NASA invented an "initialized fractional calculus" to deal with this. You might find it interesting. Kevin Baastalk 17:53, 14 January 2009 (UTC)

## En dash

As the editor who added the bit to the Wikipedia Manual of Style about en dashes being used in compound adjectives for which neither part of the adjective modifies the other, I thought you might be interested in knowing that a couple editors are now disputing that in part over at Wikipedia talk:Manual of Style#en dashes vs hyphens. (As a side note, WikiBlame rocks.) --Wulf (talk) 06:18, 15 March 2009 (UTC)

## Singleton pattern revision

I understand that you wanted to clean up the samples and consolidate into one language (Java), but as a developer myself, I enjoyed seeing the different examples.

The C# sample comes in handy, and it was interesting to see how simple it is to implement in Ruby.

Is trimming the samples really the best solution? Not everyone has a Java background.

Makotosan (talk) 15:25, 9 April 2009 (UTC)

It may be handy, but I don't see how it helps explain the singleton pattern. Let's discuss this at Talk:Design_pattern_(computer_science)#Extraneous Examples. —Ben FrantzDale (talk) 15:42, 9 April 2009 (UTC)

## Traction (engineering)

I've reverted your bold changes , reasons

• There is a proposal (see the talk page to merge 2 other articles into the page) please read that - adding both would go to form a fairly broad article.
• The article had clear (and numerous references) to the commonly accepted meaning of the word "traction" including dictionary and engineering handbook definitions. When I found the article it read " traction is a vector vector field defined over the surface of an object describing the force distribution over the surface" if there is an alternative definition such as this please bring it up on the talk page - don't delete the other obvious meanings - the pressure definition seems to be describing "traction force distribution" or "traction pressure"FengRail (talk) 16:02, 14 April 2009 (UTC)

Please excuse my swearing in the edit summmary.

As far as I can tell what you describe may be the "traction vector" [1]

I'd suggest an addition something like "In tensor analysis the meaning of traction is further extended to be the force exerted per unit area, with units of pressure, and named the traction vector.

Personally I think there may be a good case for a separate article and disambig - with a page Traction (tensor) or Traction (finite element), or maybe Traction (finite element, engineering) - as the two definitions are quite different in scope of topic. Again please discuss on talk page of traction. Thanks.FengRail (talk) 16:25, 14 April 2009 (UTC)

I think probably traction tensor (engineering) is the best title, which would be well worth writing, and useful to link to for me. (as it is important in discussions of wheel/rail stress/force analysis) - which in turns relates to the much more basic topic of "traction (pulling force)".FengRail (talk) 16:29, 14 April 2009 (UTC)

I've added a disambiguation description to Traction, but no article. Please check. Thanks.FengRail (talk) 17:00, 14 April 2009 (UTC)

## Gaussian copulas

I read the article and don't understand why/how copulas are useful. I can represent the covariance of a multivariate Gaussian distribution with a covariance matrix; this is very natural. What do I gain by transforming a random variable to a multivariate random uniform and then using a copula? It seems like added complexity? What do I gain by this complexity? —Ben FrantzDale (talk) 14:02, 15 April 2009 (UTC)

Use of a Gaussian copula doesn't mean the marginal distributions are Gaussian. But I don't know the details of how these are used in finance. Michael Hardy (talk) 21:15, 19 May 2009 (UTC)

## Fair use rationale for File:Kung Fu-From Dark Angel.png

## Speedy deletion nomination of Alcas Corporation

A tag has been placed on Alcas Corporation requesting that it be speedily deleted from Wikipedia. This has been done under section A7 of the criteria for speedy deletion, because the article appears to be about a company or corporation, but it does not indicate how or why the subject is important or significant: that is, why an article about that subject should be included in an encyclopedia. Under the criteria for speedy deletion, such articles may be deleted at any time. Please see the guidelines for what is generally accepted as notable, as well as our subject-specific notability guideline for companies and corporations.

If you think that this notice was placed here in error, you may contest the deletion by adding {{hangon}} to the top of the page that has been nominated for deletion (just below the existing speedy deletion or "db" tag), coupled with adding a note on the talk page explaining your position, but be aware that once tagged for speedy deletion, if the page meets the criterion it may be deleted without delay. Please do not remove the speedy deletion tag yourself, but don't hesitate to add information to the page that would render it more in conformance with Wikipedia's policies and guidelines. Lastly, please note that if the page does get deleted, you can contact one of these admins to request that they userfy the page or have a copy emailed to you. Cutno (talk) 16:33, 15 July 2009 (UTC)

## Notation for matrix transpose

Note that the Manual of style (Mathematics) gives explicit guidance on the notation to be used for matrix transposes:

For a matrix transpose, use

please, therefore, stop using X^\top, and revert those texts you've changed to it. Jheald (talk) 22:06, 17 November 2009 (UTC)

${\displaystyle X^{\top }}$ is indeed a monstrous apparition, but don't use ${\displaystyle X^{\mathrm {T} }}$ either. ${\displaystyle X^{T}}$ is perfectly acceptable. ObsessiveMathsFreak (talk) 14:07, 18 November 2009 (UTC)

## Nice job

Nice job on the lead of covariance and contravariance of vectors. It is very nice altogether, but I have a couple of fussy little questions (of very little actual consequence) about the edit:

1. First of all, I noticed that you got rid of the "system of rigid rods" in favor of just calling it a basis. As a lecturer, I have found the rigid rods analogy to be quite helpful in communicating to students of different backgrounds. So I am somewhat reluctant to abandon this analogy altogether from the lead, in the interests of making the article as accessible as possible, but I defer to your judgment if you think otherwise. (I admit, the new version reads much more cleanly.)

2. The idea flow of the first two sentence of the "vectors" bullet point seems a little backwards to me. Would it be possible to say that the components of the vector vary oppositely, followed by saying that they contra-vary? This would seem to make the point clearer.

--Sławomir Biały (talk) 22:05, 3 December 2009 (UTC)

Re (1): I seriously doubt someone will be able to understand covariance and contravariance effectively without being comfortable with the word "basis". (I could see arguments against this, but one certainly couldn't have a deep 2+-dimensional understanding of the topic without it.) That's why I dropped it. I'm open to discussion, though :-)
Re (2): The intro really needs some diagrams. Feel free to try rewording; I agree that throwing "contra-vary" in before defining it is sub-optimal. I was having trouble describing varying the "other way" clearly and not incorrectly. —Ben FrantzDale (talk) 01:37, 4 December 2009 (UTC)

## WikiProject Industrial design and Design Portal

I recently posted the following text on Wikipedia regarding the creation of a new Visual arts/Technology-related project in Wikipedia:

WikiProject Industrial design is a Wikipedian community that aims to better organize information in articles related to Industrial design (also called Product design).

• If I'm cor-rec-to, there are about 900 articles on Industrial design in Wikipedia...
• At least, it's more than for Typography, and there IS a Typography WikiProject...
• And it's more than the Fashion WikiProject with 482 articles...
• There is also an Urban studies and planning project and a Video games portal so...
• Now you can also see a proposal for the Design Portal. (that portal would be for Industrial design AND Graphic design/Interior design)

Please support this initiative,

## Silly title

Hi,

there is a possibility to change the title of Eigenvalue, eigenvector and eigenspace. We will not be able to call it "Eigenanalysis", as you suggested, as our only possibility to get consensus (and to avoid other changes in the future) is to follow the literature, which almost always uses "Eigenvalues and eigenvectors" for similar articles or textbook chapters.

Would you mind to give us your opinion? Do you agree to use "Eigenvalues and eigenvectors", the same title used in the literature? Without your support, the title would probably remain as silly as it was when MarcelB612 wrote it was silly. Please answer in Talk:Eigenvalue, eigenvector and eigenspace. Thank you

## Pruning code examples

I'd like to share with you my displeasure in the pruning of code examples from numerous different articles - specifically from articles in the software design pattern category.

• The best examples were not necessarily selected to be retained
• No attempt to gather consensus for such sweeping changes were made
• Implementation and limitations of design patterns in different languages are no longer demonstrated or discussed
• Numerous contradictions and errors to several articles were introduced due references to specific examples not being thoroughly cleaned up
• Articles were not removed from categories that are no longer applicable to the articles due to removal of examples (e.g. 'Articles with example %s code')
• As a result, the changes were degrading to the quality of several of the articles.

Although I certainly appreciate your intent and agree that just listing examples for the sake of listing examples isn't help... I think your implementation left a lot to be desired. Instead of bringing the hammer down to knock a bunch of content from multiple articles based strictly on mechanical criteria that isn't necessarily accepted communal editorial policy, make specific and well thought out edits that take into account the benefit of your change in the context of that specific article. —Preceding unsigned comment added by 67.193.73.21 (talk) 03:54, 29 January 2011 (UTC)

I agree the changes were draconian; in truth, I was intentionally being harsh. Consensus was developed earlier and a cleanup was done making the design-patterns pages not be a compendium of examples. Unfortunately, these pages are a magnet for everyone's favorite language, which isn't appropriate. While some pages definitely deserve mention across a range of languages, most are designed primarily to solve specific problems in strongly-typed object-oriented garbage-collected languages, so anything beyond Java (which I've actually never used so it's not my bias) is extraneous. I would argue that, while I did leave things dangling, I improved the pages from being a rat's nest of pet languages. My hope is that, having started Wikibook pages for each, that will act as a sink to satisfy people's passion for providing examples in Objective Scala.NET On Rails or whatever. —Ben FrantzDale (talk) 14:25, 31 January 2011 (UTC)

For example, a pixel may have 10432 electrons in it out of a possible 25000 electrons, so after A2D conversion you'd get an 8-bit digital number of 106. —Ben FrantzDale (talk) 13:57, 4 March 2011 (UTC)
The output of an A2D is a digital number, there is no argument about that, but I still struggle to see the sense of redirecting it to A2D. The output of an air pump is air, but we would not redirect air to that article. A reader typing digital number into the search box is rather more likely to be looking for numerical digit or decimal number. I suggest a redirect to one of those articles is more appropriate. SpinningSpark 16:42, 4 March 2011 (UTC)
I disagree. "Digital number" has a very particular meaning; I doubt you'd inadvertently go searching for it. I already bolded digital number in the intro on analog-to-digital converter, isn't that enough? —Ben FrantzDale (talk) 17:08, 4 March 2011 (UTC)
Bolding is certainly the right thing to do for a redirect, but I'm really disputing that it ought to be redirected to A2D at all. I'll open a discussion on the article page to see what others think. SpinningSpark 20:21, 4 March 2011 (UTC)
I reworked the lead of Analog-to-digital converter and removed your boldface before seeing this discussion. I was merely trying to make improvements. I would not like to see these improvements reverted. I did look for redirects and didn't see one; still do not see one. You may wish to restore the boldface but probably best to wait until we finish the redirect discussion. --Kvng (talk) 18:56, 5 March 2011 (UTC)

## Digital number listed at Redirects for discussion

## Changes to Screw Theory

I have been working to revise the article on screw theory and because you made contributions over the years I thought it would be a good idea to let you know. What started as small changes are slowly growing in scale. I hope you find the additions to be useful. Prof McCarthy (talk) 05:46, 29 June 2011 (UTC)

## Eigenvalue perturbation

Hi,

I stumbled upon the page Eigenvalue_perturbation that you wrote; it's very useful to me and I'd like to use it in my thesis. On Talk:Eigenvalue_perturbation you wrote that it comes from your old notes from a course. I would like to get more information... Do you remember if the course had some kind of textbook that I can get from my local library? Maybe you can give the name of the professor so I could ask him by email?

Thanks, Alex --132.67.192.131 (talk) 12:47, 12 July 2011 (UTC)

Hi Alex. The course itself didn't have any text. I put the page up several years after graduating after visiting the professor, Philip Cha of Harvey Mudd College. He gave me the reference that I think I put on that wikipage. If you want more info, we can take this to emial: [Wikipedia username] at gmail dot com. —Ben FrantzDale (talk) 13:24, 13 July 2011 (UTC)
Thanks. I found a couple of sources that discuss the subject of the article, but they're talking about the simple eigenvalue problem, not the generalized one (not Ax = λBx). I'll update the page if I find something relevant. Alex 77.127.65.95 (talk) 03:44, 18 July 2011 (UTC)

## Undoing vandalism.

Be careful about using undo to fix vandalism. If the vandal made more than one edit, not only do you fail to fix all of it, but you make the fact that the article was vandalized less obvious to other editors who have it watchlisted.--Srleffler (talk) 16:48, 15 September 2011 (UTC)

## CFD for Category:Album-cover and concert-poster artists

Hello Ben. The category above is being nominated for deletion (by another editor) here. After doing some digging, I found that this category was originally created by you under the name Category:Music-related visual artists back in 2006. It's been through a few renames since, which is why I got notified about the discussion and not you. Anyway, if you'd like to comment, there's the link. Happy editing!

## Speedy deletion nomination of Rowe Furniture

If this is the first article that you have created, you may want to read the guide to writing your first article.

You may want to consider using the Article Wizard to help you create articles.

A tag has been placed on Rowe Furniture requesting that it be speedily deleted from Wikipedia. This has been done under section A7 of the criteria for speedy deletion, because the article appears to be about an organization or company, but it does not indicate how or why the subject is important or significant: that is, why an article about that subject should be included in an encyclopedia. Under the criteria for speedy deletion, such articles may be deleted at any time. Please see the guidelines for what is generally accepted as notable.

If you think that the page was nominated in error, contest the nomination by clicking on the button labelled "Click here to contest this speedy deletion" in the speedy deletion tag. Doing so will take you to the talk page where you can explain why you believe the page should not be deleted. You can also visit the page's talk page directly to give your reasons, but be aware that once a page is tagged for speedy deletion, it may be removed without delay. Please do not remove the speedy deletion tag yourself, but do not hesitate to add information that is consistent with Wikipedia's policies and guidelines. If the page is deleted, you can contact one of these administrators to request that the administrator userfy the page or email a copy to you. -- Alan Liefting (talk - contribs) 20:07, 10 March 2012 (UTC)

## Visitor pattern Motivation paragraph

Hi BenFrantzDale!

I've added a section on the Talk page of the Visitor pattern article. Since you've added quite a lot of comments on that page I thought you'd be interested in hearing that I'm trying to formulate a Motivation section, right now as a section on the Talk page. I'd be really interested in hearing your feedback since you seem to understand the Visitor pattern judging by your answers. --Objarni (talk) 08:59, 10 April 2012 (UTC)

## Gauss–Newton algorithm

Hello Ben. You have added the derivation of Gauss-Newton method with this edit. I removed it, because the derivation is already present, in a section towards the end of the article. I think it makes more sense to start with the statement of the method, then an example, then only later to go in the full derivation. Otherwise it becomes too much for readers to take. Let me know what you think. Thanks. Oleg Alexandrov (talk) 05:33, 13 January 2013 (UTC)

## entry for PTC

Hello, Ben. In the past, you've made comments on the talk page for PTC (and perhaps edits to the page itself). I work at PTC (FULL DISCLOSURE), and have noticed some out-of-date information. I placed some suggested/requested edits on the talk page, but will not make them on my own due to POC and COI rules. I'm letting you know here on your talk page that some edits are suggested there - I thought you might want to see them, since you had (have?) an interest in the page, given your past edits.

Thanks! -Alan (abelniak)

p.s.: PTC recently officially changed its name to PTC (from Parametric Technology Coropration), if you are interested: http://investor.ptc.com/releasedetail.cfm?ReleaseID=735554
