Matlab and Python implementation of Different Information Theoretical Bounds: Shannon limit, Sphere Packaging Bound, Polyanskiy bound, Union Bound, Converse, Cramer-Rao

Reproducible code for the paper "Limits of Manifold Projection in Calibrated Channel and Clutter Estimation": when projecting a calibrated channel or clutter estimate onto a specular manifold helps, when it makes the error worse, and the partial projection that never does.

Estimator or experiment? A Cramér–Rao accounting of parameter recovery by physics-informed neural networks (PINNs) and neural–mechanistic hybrids in a WNT–retinoic acid–HOX model of colorectal cancer: code, saved runs, paper and posters.

Code accompanying "Transmit and Receive Sensor Selection Using the Multiplicity in the Virtual Array" by Ids van der Werf, Costas A. Kokke, Richard Heusdens, Richard C. Hendriks, Geert Leus, and Mario Coutino

TOA/TDOA target localisation & tracking: least-squares initialiser + EKF validated against the posterior Cramér–Rao bound, with a real-time interactive simulator.

Does an IEEE C57.91 cumulative-ageing model beat "peak load" at ranking which distribution transformers fail? No — uplift +0.014 AUC against a pre-registered 0.05 threshold. A killing experiment run in two days, before building the product. Six of eight predictions hit; two informative misses.

Companion Julia code for computing time-dependent two-point correlation functions in the transverse-field Ising chain and evaluating the exact finite-temperature quantum Fisher information and its thermodynamic bounds.

Simulation study of Rydberg-atom EIT RF electrometry: Cramér-Rao-limited model fit vs MLP vs a 4-qubit data re-uploading VQC under coupling-laser drift and detection noise (3 seeds, 4-level Lindblad model).

DJCSR: D3QN-based Joint Communication-Sensing Resource Optimization xApp for O-RAN. Dynamically optimizes subcarrier allocation, power splitting, and sensing subcarrier interleaved spacing across eMBB, URLLC, and radar sensing services.

Identify the four IEC 60076-7 thermal parameters from load, ambient and top-oil telemetry, with Cramer-Rao bounds, and convert them into a dynamic loading envelope. Synthetic validation only - no field data yet.

Spectral smile estimation.

Completed research: MLE vs spectral estimation for noisy AM signals, threshold effects, CRB, and Monte Carlo.

Internal temperature of a lithium-ion cell reconstructed from surface data alone, validated against a real core thermocouple. Three estimators on identical information: a one-line algebraic relation wins at 0.141 K, the inverse PINN loses at 0.614 K. The negative result is the headline.
