Surrogate‐Optimized Flow‐Guided Miniature Condenser for Rapid Exhaled Glucose Detection
Advanced Materials Technologies, EarlyView.A surrogate‐optimized miniature condenser guides humid exhaled flow toward cold surfaces to accelerate exhaled breath condensate collection. By improving vapor access within a compact footprint, the design increases sample yield. This enables post‐collection enrichment and rapid colorimetric glucose detection from dilute exhaled biomarkers within a 5 ...

Stall Flutter Control of a Smart Blade Section Undergoing Asymmetric Limit Oscillations
Shock and Vibration, 2016 Stall flutter is an aeroelastic phenomenon resulting in unwanted oscillatory loads on the blade, such as wind turbine blade, helicopter rotor blade, and other flexible wing blades.

Analysis of Dynamic Stall on a Pitching Airfoil with Spectral Proper Orthogonal Decomposition [PDF]
, 2022 The onset of dynamic stall on helicopters pitching blades produces massive excursions in the aerodynamic loads that may couple with structure dynamics and cause its earlier failure.

Advanced Robotics Research, EarlyView.Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...

Investigations of dynamic stall and dynamic stall control on helicopter airfoils
, 2016 Investigations into dynamic stall and dynamic stall control on airfoils are detailed using pitching airfoil experiments and numerical investigations at Mach 0.3, 0.4 and 0.5 on the airfoils EDI-M109, EDI-M112 and OA209. Two-dimensional dynamic stall was investigated, and the effects of the wind tunnel interference, rotation and the finite wing on the ...
