Aligning Upper Ontologies for Defence Digital Twins
US & West ·
Researchers aligned three upper ontologies used in UK and NATO defence data infrastructure, including HQDM underlying the National Digital Twin, for the first time. A manually curated 17-correspondence crosswalk was promoted to OWL, and reasoning over the merged ontologies was performed with HermiT. The results are believed to matter beyond this specific pair.
Why it matters
Ontology alignment is crucial for data integration and building digital twins in complex organisational systems.
A concept for a digital twin of a mouse is proposed as an embodied dynamical system unifying neural activity, biomechanics, sensory feedback, and environmental interactions. Construction relies on CT, anatomical sections, and Scx-GFP imaging, along with Bonhoeffer-van der Pol neural dynamics.
A prototype system has been developed where EPICS controls beam optics simulations for the CEBAF injector, with the simulation running locally or remotely. The system models a beamline with dozens of magnets and diagnostic devices.
Investigates how many training pilots are needed when a digital twin of a wireless channel is used for channel estimation. The twin is treated as a complementary measurement fused with pilot observations. For the first time, this trade-off is formalized and quantified.
