Euler‐Top Gaussian Modes: Structured Beams From Quadratic Angular Momentum Dynamics
Nanophotonics, Volume 15, Issue 9, 13 May 2026.A new family of structured Gaussian light beams are introduced: Euler‐top Gaussian modes. Their ray‐orbital paths on the Gaussian Poincaré sphere correspond to the polhodes of the Euler top in classical angular momentum theory. This geometric and algebraic construction reveals a nonseparable mode family extending the familiar Hermite‐, Laguerre‐ and ...

Experimental investigation on ducted counter-rotating axial flow fans [PDF]
, 2011 An experimental study on counter-rotating axial-flow fans was carried out. The fans of diameter D = 375 mm were designed using an inverse method. The counter-rotating fans operate in a ducted-flow configuration and the overall performances are measured ...

Subterranean Mine Inspection Using the Prometheus Re‐Configurable Drone
Journal of Field Robotics, Volume 43, Issue 3, Page 1646-1660, May 2026.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.
