Velocities of Rotation VS Radius

DOI:

A DOI will help Author(s) easily locate a document from your citation. Think of it like a Social Security number for the article you're citing — it will always refer to that article, and only that one. While a web address (URL) might change, the DOI will never change.

Where can i find DOI:

• In IJSREM journal articles, the DOI will be printed with the article itself, usually on the footer of the page
• If the DOI isn't included in the article, look it up on the website CrossRef.org (use the "Search Metadata" option) to check for an assigned DOI.

Benefits:

• Allows for a quick and precise search.
• Article can always be located.
• Persistent link to its location on the Internet.
• Easier identification of published articles even if the metadata URL is changed.
• Aid in citation tracking, ensuring a researcher has accurate metrics on how and where their research outputs are being used or referenced.
