Actuation Strategies for Underwater Jet‐Propelled Soft Robots

Journal of Field Robotics, EarlyView.
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.

A Generalized Automated Framework for Thermal Characterization: From Bulk Materials to Complex Heterostructures

Small, EarlyView.
An automated MATLAB framework for inverse photoacoustic analysis enables precise thermal characterization of complex multilayer films. Application to electrodeposited CuxSe reveals a stoichiometry‐dependent thermal conductivity governed by lattice anharmonicity, not grain‐size scattering, in these superionic materials. ABSTRACT Precise determination of

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 ...

Considerations for the Design of Sinusoidal Slug Testing Methods

Groundwater, EarlyView.
Periodic hydraulic tests estimate aquifer properties using controlled groundwater‐level oscillations. Evaluating two sinusoidal slug‐test designs shows large motion errors when transfer‐link and flywheel ratios are high or variable. Rotating‐drive mechanisms are therefore suboptimal; stepper‐motor winches generate more accurate sinusoidal motion ...

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 ...

Modeling of Mixed Friction Interactions Occurring in Axial Piston Pumps

, 2014
Axial piston pumps are integral to a variety of hydraulic systems due to their versatility and reliability, but most attempts to model them for design purposes have failed.

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.

Mathematical Modeling and Experimental Research of Operating Parameters of an Axial Piston Water Hydraulic Pump

, 2021
Mathematical modeling and experimental research of non stationary high dynamic hydraulic processes in the pump cylinder, discharge space and intake and discharge pipe line is the fundamental in developing the piston-axial pumps.
