Design and monitor a BFR protocol: AOP/LOP-based cuff pressure (40–80%), 20–40% 1RM loads, the classic 30-15-15-15 scheme, volume reduction, elastic-vs-pneumatic guidance, a week-by-week ramp, and a contraindication screen.

Media

Transcribe a music performance into engraved sheet music: Basic Pitch note detection, grid quantization, Krumhansl–Schmuckler key finding, then MusicXML and ABC notation (plus optional MIDI) in one ZIP.

Media

Snap off-pitch vocal notes to a selected scale: pitch tracking, note segmentation, and per-note correction with before/after cents measurements.

Media

Pull the bass line out of any full mix as isolated audio, a MIDI transcription, or both — powered by local neural stem separation.

Cryptography

Simulate BLS12-381 BLS signatures end to end: Joint-Feldman DKG ceremonies, t-of-n threshold signing with Lagrange interpolation, the rogue-key attack and its proof-of-possession defense, and Ethereum 2 attestation aggregation.

Media

Add single-ended tube-preamp coloration: an asymmetric waveshaper whose bias control sets the even-harmonic warmth, with drive, tone tilt, dry/wet mix and output trim.

Media

Fold everything below your crossover to mono while keeping the stereo image above it — the elliptical-EQ move that protects vinyl cuts and mono-sub club systems.

Media

Map world tunings — 7-limit just blues, Arabic maqamat (Rast/Bayati/Hijaz/Saba) on 24-EDO quarter tones, the 22-shruti table, gamelan slendro/pelog, 31-EDO, 53-EDO and the A440 harmonic grid — onto nearest-note + RPN fine tuning, MPE 14-bit bends at ±2/±24/±48/±96 semitones, MIDI 2.0 32-bit pitch bend, the MIDI 2.0 Pitch 7.9 note attribute, and a Scala .scl export.

Security

Run a real miniature BFV/CKKS pipeline over Z_q[x]/(xⁿ+1): exact invariant-noise budgets in bits, ciphertext multiplication with relinearization, modulus switching, SIMD slot packing and a bootstrapping refresh.

Astronomy

Fit spectroscopic-binary radial velocities with a Levenberg-Marquardt orbit solver, derive the mass ratio and mass function, analyse eclipse-time O−C residuals, estimate the Rossiter-McLaughlin spin-orbit angle, and preview a geometric eclipse light curve.

ΔT_b = K_b·m·i from a solvent preset table with van't Hoff factor support and custom solvents.

C = I·t both ways — runtime from capacity or capacity from runtime — with optional voltage for Wh and W.
