An absolute continuity for positive operators on Banach lattices

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1991
For positive operators on a Banach lattice, absolute contnuity conditions are considered. An operator absolutely continuous with respect to T is compared to sums of compositions of T together with orthomorphisms or in special cases projections ...

Casimir interaction: pistons and cavity [PDF]

open access: yesJ.Phys.A41:164007,2008, 2007
The energy of a perfectly conducting rectangular cavity is studied by making use of pistons' interactions. The exact solution for a 3D perfectly conducting piston with an arbitrary cross section is being discussed.

Trickle-down racism: Trump's effect on whites’ racist dehumanizing attitudes

open access: yesCurrent Research in Ecological and Social Psychology, 2023
Reported hate crimes against Black people surged following Trump's election. While only a relatively small fraction of Americans committed these abhorrent actions, we show that Trump's victory had broader effects on the attitudes of the larger white ...

Experimental Investigation of Oil Transport during Low Load to High Load Transient in Internal Combustion Engines

open access: yesLubricants, 2023
Reducing the Lubricating Oil Consumption (LOC) has been a critical focus for engine manufacturers. LOC not only depends on engine operating condition but also the history of the operating condition variations.

Piston rotation and frictional forces between piston and cylinder of piston and motor

open access: yesProceedings of the JFPS International Symposium on Fluid Power, 1993
The influence of the piston rotation on the frictional forces between the piston and the cylinder has been studied experimentally for a swash plate type piston pump and motor. In order to measure the rotational speeds of the piston, the capacitance detecting method have been employed for the piston with the slits.

Design Sensitivity Studies on a Hydroacoustic Projector Using an Experimentally Validated Easy-to-Build Model [PDF]

open access: yesArchives of Acoustics, 2022
Hydroacoustic projectors are useful for generating low frequency sounds in water. Existing works on hydroacoustic projectors require two significant enhancements, especially for designers. First, we need to understand the influence of important projector
