PBPF FrameworkPublished

Multi-Physics Battery Pack Design in Two Seconds

A Three-Layer Coupled Framework for Integrated Battery Pack Optimisation Across Vehicle Dynamics, Cell Chemistry, and Pack Architecture

Battery pack design for electric vehicles currently takes one to two weeks per iteration. PBPF-IDO solves all three layers: vehicle energy demand, cell chemistry, and pack architecture as a single coupled optimisation in approximately two seconds, with a worked 500 km EV example included.

QRESB FrameworkPublished

Beyond Algorithm Migration

A Six-Dimension Framework for Auditable Cryptographic Security in the Post-Quantum Era

The migration to NIST-standardised post-quantum cryptographic algorithms is necessary but not sufficient. This whitepaper introduces the QRESB framework: a structured method for combining six independent evidence dimensions of cryptographic assurance into a single auditable assessment with a QRESB Assurance Index.

PSMB FrameworkPublished

Physics-Grade Cryptographic Assurance for the Quantum Era

Proving what cannot be broken. Verified, not forecast.

Instead of predicting when a quantum computer will arrive, PSMB measures the limits of what any attacker can ever physically do and expresses the result as a single, clear security margin. A positive margin means the asset is safe; a negative margin means it is provably breakable.

A1-PET · QUDL FrameworkPublished

Sharper Images, Lower Dose

A software calibration method for coincidence discrimination in PET imaging

A software-only calibration that improves how a PET scanner separates true coincidences from random and scattered ones. In simulation, it reduced random coincidence identification error from ~11% to ~1%, enabling either a lower patient dose or sharper images, retrofittable to existing scanners.

QABRE FrameworkPublished

Quantum-AI Blockchain Resilience

A real-time resilience framework defending distributed ledgers against the combined quantum and AI threat

QABRE continuously computes a live resilience score for blockchain validators, wallets, transactions and signing devices. It removes compromised validators from consensus before they can sign a malicious block, acting before damage rather than penalising it afterwards.
