Wikipedia:WikiProject Deletion sorting/Engineering

This is a collection of discussions on the deletion of articles related to Engineering. It is one of many deletion lists coordinated by WikiProject Deletion sorting. Anyone can help maintain the list on this page.

Adding a new AfD discussion

Adding an AfD to this page does not add it to the main page at WP:AFD. Similarly, removing an AfD from this page does not remove it from the main page at WP:AFD. If you want to nominate an article for deletion, go through the process on that page before adding it to this page. To add a discussion to this page, follow these steps:

Edit this page and add {{Wikipedia:Articles for deletion/PageName}} to the top of the list. Replace "PageName" with the relevant article name, i.e. the one on the existing AFD discussion. Also, indicate the title of the article in the edit summary as it is particularly helpful to add a link to the article in the edit summary. When you save the page, the discussion will automatically appear.
You should also tag the AfD by adding {{subst:delsort|Engineering|~~~~}} to it, which will inform editors that it has been listed here. You may place this tag above or below the nomination statement or at the end of the discussion thread.

There are a few scripts and tools that can make this easier.

Removing a closed AfD discussion

Closed AfD discussions are automatically removed by a bot.

Other types of discussions

You can also add and remove other discussions (prod, CfD, TfD etc.) related to Engineering. For the other XfD's, the process is the same as AfD (except {{Wikipedia:Miscellany for deletion/PageName}} is used for MFD and {{transclude xfd}} for the rest). For PRODs, adding a link with {{prodded}} will suffice.

Further information

For further information see Wikipedia's deletion policy and WP:AfD for general information about Articles for Deletion, including a list of article deletions sorted by day of nomination.

History of the metre

(Find sources: Google (books · news · scholar · free images · WP refs) · FENS · JSTOR · TWL)

Redirect to History of the metric system, merging small amounts that aren't essentially duplicated or better covered there.

This article is functionally a fork of History of the metric system, which includes pretty much everything this article might if fully developed. This article's also exceptional; we don't have "History of" articles for other units like the kilogram, second or ampere.

The forking is something of a wiki-historical accident; this article began as "Redefinition of the Metre in 1983", a redefinition in terms of the speed of light which at least one editor thought very foolish. This article may have been created to corral that issue but long arguments about it continued across many articles leading to Wikipedia:Arbitration/Requests/Case/Speed of light, this article narrowly survived an AfD but its scope was soon expanded to History of the metre, and activity on this article died down. Meanwhile History of the metric system was created, continued to be developed, and was a GA until recently. It already has much well-written well-sourced content about the history of the metre itself and its context, but broadly speaking without the digressions that this article has sometimes included.

As this isn't a new article, it seems (I've not done this before) that WP:ATD-R applies: discuss on talk page first, but if consensus is lacking, go to AfD for discussion with the wider community. Opinion at History of the metre#Redirect to History of the metric system? was divided 2:2 and so though long discussion there just might reach unanimity either way, it seems better to come here as WP:ATD-R's preferred venue.

This should be merged to Metre#History of definition, not redirected to History of the metric system. I actually don't see much duplication between the two history articles at all, I see two distinct topics with very different content. There is a lot of metre-specific history that isn't tied to the metric system as a whole and this could even be expanded. Much of History of the metre#From standard bars to wavelength of light would be out of place at History of the metric system. But for now at least, metre is relatively short and so its history could be merged there, if not kept separate if expanded. I agree with StarryGrandma on the talk page.

Igor Ivitskiy

(Find sources: Google (books · news · scholar · free images · WP refs) · FENS · JSTOR · TWL)

Page on a young Materials Scientist which claims that he is a mathematician, but has only published on polymers. According to this page he was in the Department of Chemical, Polymer and Silicate Engineering described here. While there are claims that he is a Professor, the relevant staff page does not currently verify this. Page makes many claims, for instance 200 scholarly works but he only has an h-factor of 13. (An h-factor of 13 is at about the level of a senior postdoc in Materials Science, to at most a starting assistant professor. If he was truly a mathematician then an h-factor of 13 might be acceptable.) Page has major refbombing and a fair amount of peacock. No indications of anything close to a pass of WP:NPROF on any count, or any other notability criteria. Page was previously PROD by nom, then indirectly challenged by Jars World here.

Delete: As stated in the nom, this appears to be ref-bombed. I'm not convinced by the 30 or so links, my search doesn't bring up much of anything about the person. Oaktree b (talk) 15:25, 26 June 2025 (UTC)[reply]
I find social media, youtube... The name is too common to find anything about this person. Oaktree b (talk) 15:26, 26 June 2025 (UTC)[reply]
Keep - passes GNG because he is a known young mathematician in Ukraine with significant contributions to fluid dynamics, non-Newtonian materials, and advanced computer modeling. He earned a PhD and a habilitation (Dr. Sci.) from the Institute of Mathematics, NAS of Ukraine, with research focused on nonlinear differential equations and Galilean invariance. He holds a professor title granted by the Ukrainian government for his scientific and pedagogical achievements and currently. General notability also comes from the high profile government awards. --Jars World (talk) 14:29, 30 June 2025 (UTC)[reply]

Keep Per WP:NACADEMIC: The person has received a highly prestigious academic award or honor at a national or international level, which in Ivitskiy's case is the President of Ukraine’s Prize for Young Scientists. Antoine le Deuxième (talk) 15:49, 3 July 2025 (UTC)[reply]
Neutral but lean Keep. Mostly commenting that "Young X" awards don't contribute towards WP:PROF notability when they're at the High-School, College, etc. level; they DO contribute, however, when "young" means post-doctoral and early-mid-career level. This one was earned around age 29, so looks more like the later, and can fairly be considered a WP:PROF pass; but the citation count, etc. just doesn't fully pass the "smell-test" expected if the award were really that prestigious, hence staying neutral. -- Michael Scott Asato Cuthbert (talk) 23:03, 6 July 2025 (UTC)[reply]
With apologies Michael Scott Asato Cuthbert, but I think you are misreading WP:NPROF#C2. The text in the notes is quite clear that these need to be major, senior awards. Examples would be the named awards from major national or international societies, in his case an example would be one of the awards of the European Federation of Chemical Engineering, as that is his PhD and academic research field (not mathematics). Junior or mid career awards indicate good progress, but alone rarely to never qualify at AfDs I have seen, particularly outside of mathematics. Since his citations are weak there is not a cumulative pass with a synergistic combination. Ldm1954 (talk) 04:08, 7 July 2025 (UTC)[reply]

Transformer effect

(Find sources: Google (books · news · scholar · free images · WP refs) · FENS · JSTOR · TWL)

Mutual inductance and Inductive coupling already have much more information here. The transformer effect certainly is not the WP:COMMONNAME for this, either. DeemDeem52 (talk) 16:12, 20 June 2025 (UTC)[reply]

Not delete - what are you suggesting should happen? Christian75 (talk) 12:23, 21 June 2025 (UTC)[reply]
I agree with the nom that the term is rarely used. It refers to the effect in which an emf is induced by a time-varying magnetic field. (see [1] and [2]). It is usually discussed in electrodynamics textbooks under the topic Faraday's law of induction. Given this, I propose that we merge to Faraday's law of induction, and create a redirect from the more common term, transformer emf, to that page. The coverage at the target article should also be expanded. Jähmefyysikko (talk) 17:36, 21 June 2025 (UTC)[reply]
I've added discussion about transformer emf to Faraday's law of induction. Jähmefyysikko (talk) 16:36, 23 June 2025 (UTC)[reply]
Merge as suggested. Bearian (talk) 09:23, 23 June 2025 (UTC)[reply]
Redirect to Transformer. There is nothing useful in this article to merge, it is high-school physics without sources. The name is not in common use, and I suspect is a literal translation from another language. It seems to have been created much earlier in WP history when the policy about what to include and verification was more open. I would also be OK with a simple delete, as a Google search mainly brings up pages on Transformer-syle robots. Ldm1954 (talk) 09:08, 24 June 2025 (UTC)[reply]
Redirect to Transformer, as there is not any brilliant prose or even cited content worth preserving via merge. Stepwise Continuous Dysfunction (talk) 17:31, 24 June 2025 (UTC)[reply]
Comment Technically, transformer seems like a wrong target. In those sources that care to define "transformer effect", e.g. this, it includes any effect from changing magnetic flux to a stationary circuit, similar to transformer emf. In particular, it includes the interaction between a circuit and a moving magnet, which is unrelated to what happens in a transformer. That's why I suggested Faraday's law of induction above. If we decide that it generally does not have a well-defined meaning, then we should delete it or link to Electromagnetic induction, which is the broadest article in the topic area. Jähmefyysikko (talk) 18:05, 24 June 2025 (UTC)[reply]
I would be fine with either of those as redirect destinations. Stepwise Continuous Dysfunction (talk) 23:31, 24 June 2025 (UTC)[reply]
Redirect to Inductance#Mutual inductance, where Mutual induction also redirects. In 2006 the first sentence of the first version of this article read The Transformer Effect, or Mutual Induction, describes one of the processes by which an electromotive force (e.m.f.) is induced. So it was meant as an article on what we usually refer to as mutual induction. StarryGrandma (talk) 00:45, 26 June 2025 (UTC)[reply]

Comment on Mutual inductance: The original intent of the author of the WP article does not matter, especially when the assertion that "transformer effect" is synonymous with mutual induction is unsourced. It is more important how the term is used in the literature. L.V. Kite (1974) An introduction to linear electric circuits discusses mutual inductance and says The phenomenon we have discussed here is the is the transformer effect. It occurs in circuits which are fixed in position, and should not be confused with the related phenomenon known as the dynamo effect, which depends for its existence on relative motion. This does not yet tell us whether he considers transformer effect synonymous with mutual inductance or whether it is more general phenomenon. However, he also says later that self induction [...] is obviously an additional manifestation of transformer effect. Here's another source that considers self-inductance in connection with the transformer effect: [3]. This indicates that Mutual inductance is a narrower concept than the transformer effect. Anyway, this is such a niche term that I am not strongly opposed to Mutual inductance as a target if it helps closing the AfD, since mutual inductance does lead the reader to the general topic area.
