ASME V&V 40-style in-silico trial for a repurposed closed-loop hemodynamic device -- Windkessel virtual population, verified against analytical steady state, validated against real blood-pressure data

Validated 2D/3D compressible SIMPLE/LTNE CFD solver for TPMS (Diamond/Gyroid) heat exchangers — Darcy–Forchheimer surrogate, dual air/water Nusselt closures, qNEHVI optimization, ASME V&V 20 (MMS/GCI). Shanghai 16-case: air-side Q 1.71%, grid-converged 3D Δp ≈12% / Q ≈3% (gamma_df). PySide6 GUI.

POC Vehicle Management Unit (VMU) for a power-split hybrid powertrain. This supervisory ECU coordinates the ICE and electric motor, selecting EV, ICE, hybrid, and regenerative modes based on driver demand, vehicle speed, battery SOC, and system limits, while applying basic protections for smooth, efficient operation.

Verified finite-difference solver for an axisymmetric Helmholtz resonator - MMS order 2.03, GCI ~2%, cross-validated against a second solver and published measurements.

Reproducibility package for a deterministic multigroup photon-transport verification study

5SIM Login Review 2026: activation speed, pricing, and stability tests

SecureFabric is a secure, low-latency messaging fabric designed for verified senders and end-to-end confidentiality.

Physics-informed surrogates with calibrated error bounds for nonlinear transient conjugate heat transfer. Sole-authored preprint: JAX, seed-replicated ablations, split-conformal safety bound, 104/104 claims machine-audited, reproduces in under two core-hours.

Measuring the complexity of SysML Models

IX-Style is an assured-autonomy reference architecture for aerospace systems: runtime assurance, FDIR, trust-aware degraded modes, recovery gating, operator decision support, and tamper-evident evidence for why safety-critical decisions were made.

Field-trial statistics for test and evaluation: success-run sample sizes, Wilson intervals, rule of three, Pd/Pfa/PPV with base rates, CEP50/R95, TRL evidence gates. Tested Python, standard library.

Runs declarative test sequences against a bench abstraction (simulated bench included, real-rig adapters pluggable), emits JUnit XML and regression diffs between runs.

Adjudicate, do not just reproduce. Open-source agent Skills + Python SDK for the SwarmLabs physics-informed engine, including vv-gate: a zero-dependency fail-closed verification gate that scores your predictions on published held-out sets and returns PROCEED / PROCEED_WITH_HUMAN_CHECK / BLOCK_AUTONOMOUS_ACTION. MIT.

A 101-item ground test readiness review checklist for aerospace test programs. Covers test stand readiness, instrumentation and DAQ, safety, procedures, and GSE. Free to use and adapt under CC BY 4.0.

System-level V&V portfolio project for a simplified flight control system

System Integration & V&V project for an EO/IR gimbal payload within an ISR aircraft mission system

Published held-out test sets for 62 SwarmLabs scientific scenarios (ASME V&V 10-2019). Score your own model: POST predictions to /v3/verify and get an independent R2/coverage/kappa verdict plus a fail-closed PROCEED|BLOCK gate. Static JSON, digest-anchored.
