High‐Entropy Energy for Self‐Powered Systems

SmartSys, Volume 1, Issue 2, June 2025.
ABSTRACT In energy constrained application scenarios, self‐powered systems (SPSs) are gradually emerging as a core technological pathway for enabling distributed intelligent sensing. High‐entropy energy, such as micro‐wind, vibrations, water motion, and human activity, is widely available but difficult to harness due to its low density, randomness, and

On a fair and risk‐averse urban air mobility resource allocation problem under demand and capacity uncertainties

Naval Research Logistics (NRL), Volume 72, Issue 1, Page 111-132, February 2025.
Abstract Urban air mobility (UAM) is an emerging air transportation mode to alleviate the ground traffic burden and achieve zero direct aviation emissions. Due to the potential economic scaling effects, the UAM traffic flow is expected to increase dramatically once implemented, and its market can be substantially large.

A Resilience‐Driven Concept to Manage Drone Intrusions in U‐Space

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
With the U‐space revolution, drones are not only going to reshape both the physical space and the cyberspace of the future urban environment but are also introducing new multi‐domain risks. This work proposes a concept for improving the U‐space resilience through a novel service, named DARS (drone attack resilience service), relying on an artificial ...
