Applications in Plant Sciences, EarlyView.Abstract Premise There is a knowledge gap regarding how foliar injury and restricted water uptake can be detected by measuring root dielectric response. This pot study nondestructively evaluated the efficiency of real‐time dielectric measurement to monitor the effects of glyphosate spraying.

A coupled hydraulic and mechanical system simulation for hydraulic excavators
Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 2019The hydraulic system of an excavator consists of a central hydraulic power source and multiple actuator circuits. The numerical stiffness of the hydraulic system model, the complex hydraulic circuits of the excavator, and the coupling of the dynamics associated with the hydraulic system and mechanical manipulator have been major barriers to developing ...

New Hydraulic System Modelling
Journal of Vibration and Control, 2004The efficient design of hydraulic systems requires fast simulation methods. In most simulation programs, the hydraulic components are coupled by compressible joints. Since the compressibility of oil is very small, this leads to stiff differential equations.

Design of the hydraulic absorber for hydraulic catapult system
Proceedings of 2011 International Conference on Fluid Power and Mechatronics, 2011Hydraulic catapult is a high speed fluid power based launching system and the actuator is a 3-level telescopic cylinder. Limited by the traveling distance of the cylinder, There is no much room left for the cushion process, which leads to the impossible apply of the traditional hydraulic absorber.

The hydraulic vortex - an autocatakinetic system
International Journal of General Systems, 2006Experiments were performed to provide a phenomenological explanation of how a hydraulic (water) vortex forms. Experimental observation and results gathered from this work also provided a possible explanation as to why such a vortex forms. The data and interpretations presented are intended to support the classification of the hydraulic vortex as a self-
