Cross-validation is Insufficient for Model Validation

In this report, we review the foundations of cross-validation and draw attention to common, but underappreciated, assumptions.

A Description of a New Model of Sporadic E for JORN

This paper describes a new fully automatic data driven real-time model of the morphology of Es, and describes the associated expected propagation characteristic that should reduce the need for manual intervention. It has been adapted to work with JORN ionospheric sounder data in real time and tested with years of data.

A Study of Relativistic Bounds on Clock Synchronisation on Earth

In this report we investigate the extent to which a high-precision clock might be able to synchronise another to its own time, when they are part of a network that requires time-stamping events to a very high precision.
