Digital Twin‐Based Optimization of Service Availability in LEO Mega Constellations Considering Handover Delays in Open RAN

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT As non‐terrestrial networks (NTNs) become integral to future 6G systems, ensuring seamless connectivity and service continuity over low Earth orbit (LEO) satellite constellations is essential. This work investigates the impact of open radio access network (RAN) functional splits on handover performance in NTNs, focusing on minimizing service ...

Scale‐aware impact modelling for atmospheric releases of radioactive material

Weather, EarlyView.
Since the Fukushima nuclear power plant disaster in 2011, the UK has developed the process of Joint Agency Modelling (JAM), which provides advice to government in case of atmospheric releases of radioactive material. The timely deployment of JAM requires a prior estimate of the extent to which impacts could reach. Thus, to develop a fast pre‐calculator
