[edit] CMRR

[1] Why 1/2 As instead of just As? — Omegatron 15:07, 26 February 2007 (UTC)

This is what I understood from the -- somewhat obscure -- explanation that was originally on the page: As is the amplification factor for a voltage Vsin that is on both inputs. So if V+ = V- = Vs, then Vs = (V+ + V-)/2. It could be that the original definition was wrong, I didn't check that. I agree that the equation looks kind of asymmetric with the factor 1/2. It would make 6 dB difference (on typically 90 dB) if you leave out the factor 1/2. Han-Kwang 18:36, 26 February 2007 (UTC)

Oh, I see. It depends on the circuit model you are using. [2] [3] — Omegatron 00:42, 3 March 2007 (UTC)

[edit] Chicken (food) article

On your user page, it says your interests include adding nutritional information to food articles. The chicken (food) article does include nutritional facts on a broiler chicken with skin, it'd be excellent if the article would address the nutrition of skinless chicken breast and perhaps if there's any difference nutritionally between white meat and dark meat. Anyway, just thought it'd suggest it as a possible project; I'd appreciate it. Thanks.--Grendlefuzz 10:22, 1 March 2007 (UTC)

Thanks for the feedback. I'm rather busy these days, which means that I have no time for intensive wikipedia editing (and watchlist monitoring). So far I haven't received a lot of feedback on these templates, but I certainly have no problem if you make a WP project out of it. I've mainly added data on vegetables and fruits because meats and processed products are too inconsistent. For example, on the beef page you would need separate tables for all different parts of the cow, which would clog up the page too much. But if you find a way of presenting data that won't cause controversies I'd say go for it. Most data comes from the USDA nutrient database. Han-Kwang 15:21, 1 March 2007 (UTC)

[edit] MIIPS

Thank you very much for your comments. As most others, I started to use Wikipedia so frequently, then, I think that I should share with others the knowledge I know. That's the point of my starting with MIIPS. It is an exciting technology to further push the power of ultrashort pulse to application through pulse characterization and phase modulation.Xipeng 17:50, 26 March 2007 (UTC)

[edit] Yerba Maté

The New Oxford American Dictionary, the Oxford English Dictionary, the American Heritage Dictionary of the English Language and the Merriam-Webster's Online Dictionary all spell it yerba maté with an accent. You can check them all if you wish. This spelling is even stated in the Wikipedia article. Hey, I don't like it either. I speak Spanish natively and find it totally silly, but that's the way things are and our "duty" is to inform what's documented. —☆ CieloEstrellado 11:27, 1 April 2007 (UTC)

[edit] Laser

Sorry, I didn't notice you had re-written the intro. I saw the previous user's vandalism, and reverted to the last version I could recongnize as familiar; unfortunatly, I did not notice it was not the vandal who had changed the text, rathern than you. My apologies. · AO Talk 17:54, 7 April 2007 (UTC)

[edit] Svenska?

Hej, var bara tvungen att fråga, varför kan du svenska? :) Jack Daw 22:45, 7 April 2007 (UTC)

Jag jobbade på Lunds Universitet några år. :-) (och jag har också varit körledare till en svensk kör här i Nederländerna en stund, när deras dirigent hade uppsagt sig. Men jag tror inte att det är typiskt. Detta för att svara på din fråga på Talk:Conducting. :) Han-Kwang 23:06, 7 April 2007 (UTC)

[edit] Re: your recent comment at Talk:Laser

I'm putting this on your Talk page because its just nitpicking, and not relevant to the discussion going on there. You wrote "Also in telecom, lasers have a fairly large bandwidth because they are pulsed lasers." Compared to other lasers, semiconductor lasers might be fairly broadband, but that's as much because of the short cavity as the modulated) operation. And in telecom applications its definitely preferred to have a narrow laser linewidth, to maximize the achievable fiber bandwidth. I thought for long distance systems, they're usually CW (with an external modulator) for that reason; or is that all out-of-date information and the modulation itself is nowadays enought to make the linewidth "broad" by some definition? -- The Photon 02:46, 13 April 2007 (UTC)

A friend of mine has been working in optical communications research, and explained his work to me, but I'm not an expert myself and it was a while ago. Now that I'm thinking of it, I believe you're right and it was rather multiple narrowband lasers which drive the same fiber. But along the fiber, optical amplifiers (which amplify by stimulated emission) can be used to amplify the whole bandwidth in a single gain medium. Han-Kwang 07:13, 13 April 2007 (UTC)

[edit] FASOR

Greetings. I want to get your opinion on FASOR (laser physics) since you have been involved with it a bit. As I posted on the talk page, I don't think this is even a real legitimate term. There is only one reference to FASOR as a term that I can find, and it is a conference paper. I certainly don't think that it is notable as a term. I mean, lasers generated by diference frequency aren't called FSSORs are they? I am just not sure I am buying the FASOR thing. Let me know what you think! --Chuck Sirloin 18:19, 3 May 2007 (UTC)

(crossposted to article talk page) The description makes sense, but I didn't consider notability. I created this article because I thought the elaborate descriptions with all articles that included Image:Starfield Optical Range - sodium laser.jpg and in laser were not in place there. I believe the image description originally stated that it was a dye laser, which turned out to be wrong. I think Deglr6328 (talk · contribs) digged up the information, as in this edit. Maybe Deglr6328 knows more. If you are right, it might be more appropriate to put it at the image description, or maybe at the starfire Optical Range page. Han-Kwang 20:14, 3 May 2007 (UTC)

[edit] You were there, only you can understand it better

If there is anybody who can understand half of what I went through with BiggyP and Voy7, that's you. I'd like to invite you to read this at the Community Sanction Noticbeboard [4]. I thank you for your time.Jrod2 17:44, 8 May 2007 (UTC)

I had a look at it, although I didn't dig up all discussions. What I saw were pretty heated discussions. In any case, BiggyP and sockpuppets are all blocked forever. Certainly I can understand very well how angry the attacks made you, but if you find yourself in such a situation again, it's beter if you take a deep breath and try to compose a diplomatic answer rather than trying to retaliate. When I read back a dialogue on a talk page, I tend not to take the party that is screaming and behaving very emotionally very seriously. Han-Kwang 20:43, 8 May 2007 (UTC)

Hey! Nice that you replied and you are doing the rounds! Thanks for the advise, the problem with Biggy P was that, he was slandering and smearing a living person's good name and thus, I was forced to confront him. He made a choice to destroy me, so I just defended myself. In the end, Justice does prevail sometimes.Jrod2 00:40, 16 May 2007 (UTC)

[edit] Yoghurt

I want to start out by saying I'm really sorry that this happened - I did my best to stop it (since the discussion has happened so many times), but sadly I have been overruled by 4 people who are obsessed with name changing (regardless of whether or not I agree with them). There is a new debate on the Yoghurt talk page about the move - I just felt it would be best if most people who had voted in the past knew about this.danielfolsom 00:04, 16 May 2007 (UTC)

Have a look at Wikipedia:Canvassing. I feel tempted to vote for yogurt just to discourage spam-like behavior. Han-Kwang 15:53, 16 May 2007 (UTC)

[edit] Dietary reference intake merge

Hello, I think you made two mistakes in the merge. First, you only waited two days for comments, which I think is too short, and second, you merged a large article with a long history into a stub by copy/paste. In such cases an administrator should do a page merge that actually preserves the page history. I think you should revert your actions and do it again following the appropriate procedure. Han-Kwang 07:14, 18 June 2007 (UTC)

Well I am an administator, and I can tell you that it is not possible to merge two articles with existing text by doing a page move. A cut-and-paste or cut-and-rewrite is necessary, though for copyright reasons you should note the from/to article in your edit summary, which I did. There were already comments on Talk:Reference Daily Intake in support of a merger in 2006, so I assumed that this merge was not controversial. Do you have an actual objection to the merger? -- Beland 07:23, 18 June 2007 (UTC)
I'm sorry, I was thinking of Wikipedia:How to fix cut and paste moves, but this is apparently the conventional procedure for merging. Regarding support: the discussion you're referring to was about Daily Values, not Dietary reference intake. I agree that there was a lot of overlap between the articles, but didn't see a discussion about which term was the appropriate article title. For now, it's best to leave it alone unless someone else has more to say about it. Han-Kwang 08:41, 18 June 2007 (UTC)
