Flow versus pressure control of pumps in mobile hydraulic systems
This work studies an innovate working hydraulic system design for mobile applications, referred to as flow control. The fundamental difference compared to load sensing systems is that the pump is controlled based on the operator’s command signals rather than feedback signals from the loads. This control approach enables higher energy efficiency since the pressure difference between pump and loa...
متن کاملStarling resistor versus compliance. Which explains the zero-flow pressure of a dynamic arterial pressure-flow relation?
Arterial pressure at zero flow (Pz = 0) that is higher than venous pressure (Pv) in dynamic pressure-flow relations has been explained by the presence of an arteriolar Starling resistor (SR) mechanism (i.e., vascular waterfall) or the discharge of vascular capacitance. To determine which was predominant, I studied in vivo hind limbs of 18 anesthetized dogs in which femoral arteries were cannula...
متن کاملMicrofluidic flow focusing: drop size and scaling in pressure versus flow-rate-driven pumping.
We experimentally study the production of micrometer-sized droplets using microfluidic technology and a flow-focusing geometry. Two distinct methods of flow control are compared: (i) control of the flow rates of the two phases and (ii) control of the inlet pressures of the two phases. In each type of experiment, the drop size l, velocity U and production frequency f are measured and compared as...
متن کاملComparison of expiratory isovolume pressure-flow curves with the stop-flow versus the esophageal-balloon method.
BACKGROUND Expiratory isovolume pressure-flow curves allow determination of flow limitation and airway resistance, but obtaining an isovolume pressure-flow curve requires placing an esophageal balloon. The stop-flow method of obtaining isovolume pressure-flow curves is easy and noninvasive. OBJECTIVE To compare the stop-flow and esophageal-balloon methods by measuring the differences between ...
متن کاملAmbulatory versus home versus clinic blood pressure.
Ambulatory Versus Home Versus Clinic Blood Pressure To the Editor: There is growing evidence that blood pressure (BP) monitoring and home BP monitoring are useful for predicting hypertensive target organ damage and the risk of cardioand cerebrovascular events. Ambulatory BP monitoring and home BP monitoring have been reported to be better predictors than clinic BP in many population studies. In...
