Deep technical writing on the math behind our engines — how the classical methods work, where they fall apart, and what changes when the same problem is solved deterministically. Free to read; CC-BY where citation matters.
Selective Harmonic Elimination Explained: From the Equations to a Deterministic Solver
Why classical Newton-Raphson methods miss most solutions, what "every viable solution" really means, and how a deterministic SHE solver changes the engineering workflow for UPS, VFD, and motor drive applications. Covers the math, the five physical optimization objectives, and the textbook verification protocol.
IEEE 519 and Selective Harmonic Elimination: A Practical Compliance Guide
IEEE 519 explained from the limit tables to the field strategy. The four compliance strategies (PWM, passive filter, active filter, SHE), why SHE is structurally the right tool for megawatt-class installations, and what a reproducible verification chain to MATLAB fsolve actually looks like.
Direction-of-Arrival Estimation: When MUSIC and ESPRIT Aren't Enough
Subspace methods explained, the Cramer-Rao Lower Bound, why threshold tuning is fragile under low SNR, and the case for CRB-efficient deterministic DOA estimation. Covers the threshold effect, coherent-source fragility, and how the public Zenodo benchmark dataset lets anyone reproduce the gap themselves.
Phased-Array Synthesis: The Tradeoff Between Null Depth and Sidelobe Level
Why the SLL/null-depth tradeoff has historically been fundamental, how certified per-design proof artifacts change the engineering review cycle, and what verification against MATLAB's Phased Array Toolbox actually proves.
Passive RF Geolocation vs. Active Radar: A Practical Comparison
When passive emitter localization beats active interrogation: counter-UAS, contested airspace, GPS-denied operations, and the role of distributed cognitive EW state machines.
Why Your CRC Retries Are Costing You: Reversible Payload-Layer Error Correction Explained
Software-only payload-layer error correction. How to turn ~86% of CRC retry events into in-place corrections with 100% detection and zero false corrections.
Stage-Edge Contract Verification: How LCRE Finds the First Edge That Broke
Why downstream symptom suppression is the wrong answer, how stage-edge contracts emit structured proof artifacts, and what 1 ms detection looks like in practice.
