Double Helix Structure for Stable Flexural Actuation in Soft Robotics
Advanced Intelligent Systems, EarlyView.This work introduces a double‐helical architecture for soft robotic actuators that enhances twisting resistance, increases output force, and minimizes undesired deformation. Actuators driven by shape‐memory alloy wires exhibit a roughly fivefold higher torsional/flexural stiffness ratio and 50% greater force output.

Urban wind energy conversion: the potential of ducted turbines [PDF]
, 2008 The prospects for urban wind power are discussed. A roof-mounted ducted wind turbine, which uses pressure differentials created by wind flow around a building, is proposed as an alternative to more conventional approaches.

American Journal of Agricultural Economics, EarlyView.Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

Research on the Power Output of Different Floating Wind Farms Considering the Wake Effect
Journal of Marine Science and EngineeringFor floating wind turbines, one of the most interesting and challenging issues is that the movement of the rotor is strongly related to its floating platform, which results in corresponding variations in the wake characteristics of the turbine.

Research on Diaphragm Pump Fault Diagnosis Method Based on Res‐DCB‐Net
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Nonstationary pressure pulsation signals of diaphragm pumps contain strong background noise and coupled characteristics. This makes it challenging to extract incipient fault features and to decouple faults with similar physical mechanisms. To address these limitations, this paper proposes a spatiotemporal fault diagnosis model named Res‐DCB ...
