Radiation efficiency of a distribution of baffled pistons with arbitrary phases.

open access: yesJournal of the Acoustical Society of America, 2022
The radiation resistance and efficiency of a collection of circular pistons, randomly placed on a plane and vibrating with arbitrary phases, are expressed as a combination of the self- and mutual-radiation components.

SEMITRANSPARENT PISTONS [PDF]

open access: yesQuantum Field Theory Under the Influence of External Conditions (QFEXT09), 2010
We consider semitransparent pistons in the presence of extra dimensions. It is shown that the piston is always attracted to the closest wall irrespective of details of the geometry and topology of the extra dimensions and of the cross section of the piston. Furthermore, we evaluate the zeta regularized determinant for this configuration.

Capped piston: A promising design to reduce compressibility effects, pressure ripple and cavitation for high-speed and high-pressure axial piston pumps

open access: yesAlexandria Engineering Journal, 2023
Raising rotational speed and operating pressure is an effective way to increase the power density of axial piston pumps. However, the axial piston pump with standard hollow pistons suffers from problems of volumetric losses, pressure ripple, and ...
