Investigation of Using Sky Openness Ratio as Predictor for Navigation Performance in Urban-like Environment to Support PBN in UTM

Sensors, 2022
One of the causes of positioning inaccuracies in the Unmanned Aircraft System (UAS) is navigation error. In urban environment operations, multipaths could be the dominant contributor to navigation errors.

Weaponising the Supply Chain: Yemen's Blockade and the Contradictions of Maritime Logistics Capital

Antipode, Volume 58, Issue 1, January 2026.
Abstract This paper examines the 2023–2025 naval blockade imposed by Yemen in the Red Sea. It argues that the blockade's success in disrupting global trade stemmed from the potent confluence of asymmetric military tactics and the structural vulnerabilities inherent within global maritime logistics capitalism.

RRT and Velocity Obstacles-based motion planning for Unmanned Aircraft Systems Traffic Management (UTM)

, 2023
In this paper, an algorithm for Unmanned Aircraft Systems Traffic Management (UTM) for a finite number of unmanned aerial vehicles (UAVs) is proposed. This algorithm is developed by combining the Rapidly-Exploring Random Trees (RRT) and Velocity Obstacle (VO) algorithms and is referred to as the RRT-VO UTM algorithm.
