Air cooling is being pushed to its limits in data centres, with racks now pushing tens of kilowatts and localised areas of the accelerator reaching at 100 W cm^-2. The architecture most frequently suggested to replace it is immersion cooling, where electronics are in direct contact with a dielectric liquid. Still, the literature backing this replacement is very disjointed—results are reported at varying spatial scales, reported in different system boundaries, and with incom [...]

Dynamic Positioning (DP) systems are widely used in offshore operations such as drilling, subsea construction, cable laying, offshore renewable energy support, and remotely operated vehicle (ROV) operations. As offshore activities become increasingly dependent on DP capability, failures in DP systems may result in operational disruption, safety concerns, and environmental exposure. Although advances in automation and redundancy have improved DP system reliability, the offshore industry continues [...]

The Internet of Underwater Things (IoUT) has significantly improved underwater communication. However, due to the unique and challenging characteristics of underwater acoustic channels, such as long multipaths, high propagation delay and Doppler variation, and severe energy and bandwidth limitation, IoUT networks are highly vulnerable to security threats. These conditions make conventional Internet of Things (IoT) intrusion detection systems (IDS) less effective. Improving the security of IoUT n [...]
