This repository is intended to be credible to engineers. Credibility requires:
- primary sources where possible,
- vendor datasheets for components,
- clear separation of what is measured vs assumed,
- and strict avoidance of copying copyrighted text.
This file defines how we cite and how we keep references clean.
You must cite a source when you:
- reference a known thermoacoustic concept, equation set, or design guideline beyond basic definitions,
- propose performance ranges that are not directly measured in this repo,
- specify a component capability (bandwidth, accuracy, operating temperature, pressure rating),
- claim a material property or a standard (outgassing, vacuum compatibility, etc.),
- reference industry practices (e.g., measurement methods, calibration standards).
Preferred order:
- Peer-reviewed papers and textbooks (primary technical sources)
- Government/standards documents (NASA, NIST, ISO, IEC, etc.)
- Manufacturer datasheets (for parts and sensors)
- Reputable technical articles (only if primary sources are unavailable)
Avoid:
- unsourced blog claims
- marketing-only pages without numbers or datasheets
- “mystery” forum posts unless they link to primary sources
- Use a short, consistent format in markdown:
- Author(s), Title, Venue/Publisher, Year, DOI/URL (if available)
- If the citation supports a specific statement, place it immediately after that statement.
Example:
Thermoacoustic engines can convert a temperature gradient into acoustic power under appropriate impedance conditions.

- Do not paste large sections from papers, books, or datasheets.
- Do not paste vendor drawings unless explicitly permitted.
- Summarize in your own words and cite the source.
Rule of thumb:
- If you need the exact text, quote only a short excerpt and keep it minimal.
- Prefer paraphrase + citation.
- Any numeric claim should be one of:
- measured in this repo (with dataset + method),
- a stated assumption (explicitly labeled),
- or a cited value (with source and context).
- If you can’t cite it and you didn’t measure it, label it as an assumption and provide a test plan to verify.
When adding part numbers:
- include a linkable datasheet reference (manufacturer preferred)
- record key specs used:
- temperature rating,
- pressure rating,
- sensor bandwidth,
- accuracy/tolerance,
- electrical ratings.
If a vendor does not provide a real datasheet, do not use the part as a baseline recommendation.
- Keep a running list of references in
docs/REFERENCES.md. - When a doc section relies on a reference, add it to
docs/REFERENCES.mdand cite it in the doc. - Avoid “citation dumping.” Cite only what supports the claim.
A reviewer should be able to:
- trace each key assertion to either (a) measurement, (b) assumption, or (c) citation,
- reproduce the model outputs from
models/, - and reproduce the test workflow from
test/.
If that chain breaks, the repo loses credibility.
If a new reference contradicts an old one:
- keep both in
docs/REFERENCES.md, - and update the affected section with a clear note explaining the difference.
