Global Kilometer‐Scale Climate Storylines Using Spectral Nudging
Abstract Effective climate adaptation benefits from detailed, actionable information on how specific extreme events are influenced by climate change. Here we present the first global, kilometer‐scale coupled modeling framework that enables counterfactual reconstructions of recent weather events, including extremes, in different climates.

Star formation, which drives the evolution of baryonic matter in the universe, occurs in the densest regions of the interstellar medium. As a result much of the emergent short wavelength radiation, UV to near IR, is absorbed by intervening dust and ...

Testing the Strength of Buried Surface Hoar Weak Layers Under Combined Compression and Shear Loading
Abstract We experimentally determined the multiaxial strength of weak layers of buried surface hoar using displacement‐controlled tests under combined normal and shear loading on a custom testing machine. We tested 63 samples from three different weak layers, with strengths ranging from 1 to 10 kPa with considerable scattering. While shear strength was

Enhanced Operation Mode Design and Motion Control of a Dual-Redundancy Electro-Hydrostatic Actuator
In dual-redundancy electro-hydrostatic actuators (EHAs), the dual pumps are mainly designed for safety, where the cylinder is controlled mainly by one pump while the other one is standby for redundancy. However, such a strategy is basically like a single-

Dynamic Analysis of Electro Hydrostatic Actuation System
AbstractMore electric aircraft initiative has led to Fly-By-Wire (FBW) and Power-By-Wire (PBW) technologies. PBW technology has several advantages and has potential for weight reduction and energy saving compared to conventional hydraulic system. Recent development in aviation technology have combined the electric and hydraulic system and arrived at ...

Numerical and Experimental Analysis of Composite Hydraulic Cylinder Components
Due to a number of advantages, such as the high power-to-weight ratio of the system, the possibility of easy control and the freedom of arrangement of the system components on the machine, hydrostatic drive is one of the most popular methods of machine ...

Hydrostatic actuation for wearable robotics
Exoskeletons require energy efficient actuators of low mass and volume (to increase wearability) with controlled output force, sufficient for full gait support. The main research objective of this work was to develop such an actuator.First, the concept of the passive return electro-hydrostatic actuator (PREHydrA) was developed.
