Reproducible Edge-to-Cloud ECG Stress Detection with Embedded Telemetry and Hardware-in-the-Loop Validation

10,000-Packet Physical HIL Validation • 4D Hyperchaotic Stream Cipher • 15-Fold LOSO Benchmark

Mitigated inter-subject baseline variability across 15 WESAD benchmark subjects using relative baseline calibration: X* = (X - Bs) / (|Bs| + ε). Validated with bare-metal STM32G474RE ARM Cortex-M4 edge DSP, continuous 4D hyperchaotic stream cipher (M-4DCHS), and a physical 10,000-packet zero-loss HIL testbed.

Second-Order Memristor Circuit Emulator & Hopfield Dynamics

Emulated a dual-state active memristor in LTspice using CFA/multiplier stages and verified frequency-dependent pinched hysteresis from 5–80 kHz; modeled a 5D memristive Hopfield network in MATLAB, reproducing a 4-butterfly chaotic attractor (M = 2).
