Numerical simulation driven Cycle-GAN for domain generalization-based fault diagnosis of axial piston pumps

Engineering Science and Technology, an International Journal
Deep learning models have been extensively employed for the fault diagnosis of axial piston pumps but they require abundant labeled fault data for model training.

Actuation Strategies for Underwater Jet‐Propelled Soft Robots

Journal of Field Robotics, Volume 43, Issue 6, Page 3868-3892, September 2026.
ABSTRACT This review article examines jet‐propulsion mechanisms in underwater soft robotic systems, focusing exclusively on physically fabricated and experimentally validated robots. Covering research published from 2013 to 2025, this study classifies and evaluates jet‐propulsion robots based on their actuation mechanisms.

Resource reallocation across successive systemic innovations: How Rolls‐Royce shaped the evolution of the turbojet, turboprop, and turbofan

Strategic Management Journal, EarlyView.
Abstract Research Summary Despite the importance of resource reallocation in shaping a variety of strategic outcomes, strategy scholars have paid only limited attention to the processes by which firms reallocate their resources across successive systemic innovations.

In situ mapping of iron oxidation in laminar metal fuel flames using X‐ray absorption spectroscopy

Journal of Synchrotron Radiation, EarlyView.
For the first time an iron metal flame has been mapped by in situ X‐ray absorption spectroscopy. Strong gradients in oxidation state and phase composition across the metallic core and the flame front were found with FeO peaking at the visible flame front and Fe3O4 forming further beyond.Metal fuels such as iron are promising carbon‐free energy carriers

4D imaging of a porous carbonate rock under triaxial loading: quantitative correlation between local porosity and strain

Journal of Synchrotron Radiation, EarlyView.
A 4D X‐ray computed tomography experimental campaign was carried out on a porous carbonate rock to investigate the link between initial porosity and deformation modes. This paper presents the experiment and the methods used to explore this relationship.The study of the mechanical behaviour of carbonate rocks has benefited from the evolution of ...

Isometric training at longer muscle–tendon complex lengths: A potential countermeasure to impaired neuro‐muscle–tendon function during space travel

Experimental Physiology, EarlyView.
Abstract Manned space exploration to distant destinations, including Mars, continues to be an aspiration of humankind. Space travel does, however, present many challenges to the body, amongst which adaptation to microgravity is perhaps the largest. For instance, both short and long manned spaceflight missions have shown substantial deleterious effects ...

Impaired Windkessel function and proximal aortic stiffness: Linking vascular ageing to cognitive decline

Experimental Physiology, EarlyView.
Abstract Central arterial stiffening, particularly of the proximal aorta, is increasingly recognised as a pivotal contributor to cardiovascular disease, dementia, and mild cognitive impairment. Loss of Windkessel function amplifies pulsatile pressure, reduces diastolic perfusion and accelerates microvascular damage in the brain.

Research on the Influence of Piston Pair Wear on Pump Output Characteristics of Axial Piston Pump Under Multiple Working Conditions

Machines
To clarify the nonlinear degradation of volumetric performance caused by piston–cylinder wear in axial piston pumps under multiple operating conditions, this study develops an integrated framework linking local wear-induced leakage to whole-pump output ...

A computational model of axial piston swashplate pumps

Energy Procedia, 2017
Abstract Variable displacement hydraulic machines offer a very promising alternative and energy saving solution for many applications in mobile machines, mobile robots and other applications. In the present paper an axial piston swashplate pump will be theoretically analyzed and explained using the software AMESim in order to estimate the piston ...
