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.

Uncovering renewable energy policy impact channels on land values, the local farm structure, and farmland heterogeneity

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 ...

Design and testing of a contra-rotating tidal current turbine [PDF]

, 2005
A contra-rotating marine current turbine has a number of attractive features: nearzero reactive torque on the support structure, near-zero swirl in the wake, and high relative inter-rotor rotational speeds.

Separation and Valorization of Chlorine From Tail Gas Streams

Angewandte Chemie International Edition, EarlyView.
A commercially available ion exchange resin was found to adsorb chlorine gas selectively in the presence of other gases reversibly forming the corresponding trichloride species [IEx][Cl3]. This discovery was telescoped to an efficient process for the recycling and valorization of chlorine from industrially abundant tail gas streams to base chemicals ...

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 ...

Application of particle image velocimetry to wind turbine wakes [PDF]

, 1993
Wind turbine performance is critically dependent on the geometry of the rotor wake. Acquisition of detailed wake data is of major importance for further development of wind turbine studies.

Hybrid Inertial–Centrifugal Gas–Liquid Separator: CFD‐Driven Optimization Using Coupled Discrete Phase and Wall‐Film Modeling With Response Surface Methodology

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Efficient removal of liquid aerosols from compressed gas streams is essential in chemical and energy processes. Conventional separators relying on a single mechanism (inertial or centrifugal) struggle to capture both fine and coarse droplets simultaneously.

Pneumatized inferior turbinate (concha bullosa of inferior turbinate)

Malawi Medical Journal
The nasal cavity structures are prone to different anatomical variations; one of these is concha bullosa, which best known as pneumatization of the nasal turbinate. This pneumatization is a rare phenomenon to in the inferior turbinate. We report the case of an incidental finding of inferior turbinate concha bullosa in a 30- year-old female who ...
