Measurement of the Cotton Mouton effect of water vapour

, 2013
In this paper we report on a measurement of the Cotton Mouton effect of water vapour. Measurement performed at room temperature ($T=301$ K) with a wavelength of 1064 nm gave the value $\Delta n_u = (6.67 \pm 0.45) \cdot 10^{-15}$ for the unit magnetic ...

Subterranean Mine Inspection Using the Prometheus Re‐Configurable Drone

Journal of Field Robotics, EarlyView.
ABSTRACT This paper describes the design, development, and real‐world testing of an autonomous drone for subterranean exploration, known as “Prometheus.” Driven by requirements from industry that the drone be able to be deployed through areas of restricted access, Prometheus was designed to be directly deployed through a 150 mm aperture.

Doing More With Less: Cutting Food Loss and Waste in the EU and Its Impact on Food Security

Sustainable Development, EarlyView.
ABSTRACT In September 2025, the European Parliament and Council signed the law of the Revision of the EU waste framework directive, which includes also reductions for food loss and waste (FLW). This comes at a time of concern over the EU's strategic autonomy for its agrifood sector.

A modified partitioned‐stator flux‐switching permanent magnet machine for enhancing torque‐density in electric vehicle powertrains

IET Electric Power Applications
This study proposes a modified partitioned‐stator flux‐switching permanent magnet (PS‐FSPM) machine and reduces the permanent magnet usage in conventional PS‐FSPM machines. To achieve this goal, the stators of the conventional PS‐FSPM with outer‐armature/
