Half an hour, an hour, an hour and a half elapsed, and during this period of anguish, Edmond leaned over his friend, his hand applied to his heart, and felt the body gradually grow cold, and the heart's pulsation become more and more deep and dull, until at length it stopped; the last movement of the heart ceased, the face became livid, the eyes remained open, but the eyeballs were glazed.
The authors determined that crankshaft-driven positive displacement pumps generate a fluctuating volumetric flow rate, which, depending on the hydraulic response of the connected system, generates pressure pulsations.
The aim of this study was to investigate the hydraulic characteristics of pulsating flows in pressure lines piston pumps of liquefied gas, as well as the study of the effectiveness of the dampers and pressure pulsations and conformity of their parameters to calculation.
The IntegraGuard screen is setting benchmarks for minimal pressure pulsations with maximum screening efficiency.
Third, given the population of stars expected to exist in M87, and given how those stars' pulsations would add together in the light we see, they predicted how the brightness of individual pixels in an image of the galaxy would change over time.
proposed that the discharge port was an important parameter influencing the gas pulsations and the gas pulsations amplitude can be reduced by optimization of the port shape [5].
This has driven the development of better and more sophisticated time-based methods of pulsation and vibration modeling and analysis, as well as additional pulsation control "tools" and suggested practices for damping, de-tuning or canceling pulsations.
