AI‐enabled bumpless transfer control strategy for legged robot with hybrid energy storage system
CAAI Transactions on Intelligence Technology, EarlyView.Abstract Designing Hybrid energy storage system (HESS) for a legged robot is significant to improve the motion performance and energy efficiency of the robot. However, switching between the driving mode and regenerative braking mode in the HESS may generate a torque bump, which has brought significant challenges to the stability of the robot locomotion.

Heat transfer in the tip region of a rotor blade simulator [PDF]
In gas turbines, the blades of axial turbine stages rotate in close proximity to a stationary peripheral wall. Differential expansion of the turbine wheel, blades, and the shroud causes variations in the size of the clearance gap between blade tip and ...

High Voltage, EarlyView.ABSTRACT The breathing system of an oil‐immersed transformer is of vital importance for maintaining equilibrium between internal and external pressures, with any malfunction potentially disrupting the transformer's stable operation. This study develops a thermal–fluid–structure interaction (TFSI) model to simulate the breathing phenomenon in a 110 kV ...

Study of Positive Corona Discharge of Needle Plate Electrodes in Airflow
High Voltage, EarlyView.ABSTRACT For high‐speed moving objects such as aircraft and wind turbine blades, discharge occurs under strong airflow. Research on lightning attachment characteristics has been extensive, whereas the role of corona discharge in pre‐breakdown streamer development has received less attention.

Modeling of Turbine Engine Axial-Flow Compressor and Turbine Characteristics
Engineering Transactions, 1997 The paper describes the concept of modeling the turbine engine axial-flow compressor and turbine characteristics by using the function of two variables. Accuracy of the proposed concept has been verified on the example of the given compressor and turbine

The policy adjacent: How affordable housing generates policy feedback among neighboring residents
American Journal of Political Science, EarlyView.Abstract While scholars have documented feedback effects among a policy's direct winners and losers, less is known about whether such effects can occur among the indirectly affected—“the policy adjacent.” Using 458 geocoded housing developments built between two nearly identical statewide ballot propositions funding affordable housing in California, we

The SCSE Organic Rankine engine [PDF]
, 1981 The engine is the heart of a Power Conversion Subsystem (PCS) located at the focal point of a sun-tracking parabolic dish concentrator. The ORC engine employs a single-stage axial-flow turbine driving a high speed alternator to produce up to 25 kW ...

British Journal of Psychology, EarlyView.Abstract In the media, accurate climate information and climate disinformation often coexist and present competing narratives about climate change. Whereas previous research documented detrimental effects of disinformation on climate beliefs, little is known about how people seek climate‐related content and how this varies between cross‐cultural ...
