Distributions of Pulse Heights of Pre-Onset Burst Pulse Corona in Air at Atmospheric Pressure

Nanosecond pulse plasma assisted ignition simulations at atmospheric pressure

Ignition assistance by a pulsed applied voltage is investigated in a canonical one-dimensional configuration. An incipient ignition kernel, formed by localized energy deposition into a lean mixture of methane and air at atmospheric pressure, is subjected to sub-breakdown electric fields by a DC potential applied across the domain, resulting in non-thermal behavior of the electron sub-fluid form...

Investigation of Pressure Pulse Distribution in Porous Media

  Diffusivity equation commonly used for pressure distribution prediction in porous media results from substituting equation of state and continuity equation in Navier-Stokes momentum equation. From mathematical point of view this equation format shows infinite propagation speed for pressure pulse through porous media, which is physically impossible. This issue may caused by numerous assumption...

Estimation of pulse heights and arrival times

Pulse pressure and risk of new-onset atrial fibrillation.

CONTEXT Atrial fibrillation (AF) is responsible for considerable morbidity and mortality, making identification of modifiable risk factors a priority. Increased pulse pressure, a reflection of aortic stiffness, increases cardiac load and may increase AF risk. OBJECTIVE To examine relations between pulse pressure and incident AF. DESIGN, SETTING, AND PARTICIPANTS Prospective, community-based...

Determinants of pulse pressure.

We have searched to define the major arterial parameters that determine aortic systolic (Ps) and diastolic (Pd) pressure in the dog. Measured aortic flows were used as input to the 2-element windkessel model of the arterial system, with peripheral resistance calculated as mean pressure divided by mean flow and total arterial compliance calculated from the decay time in diastole. The windkessel ...
