In-cylinder flow field characteristics and evolution mechanism of unthrottled gasoline engine with Early Intake Valve Closure (EIVC) under different operating conditions

open access: yesCase Studies in Thermal Engineering
The efficiency improvement of traditional gasoline engines is hindered by a limited compression ratio due to knock and severe pumping losses caused by fixed valve lift. Unthrottled technology has emerged as a solution relying on variable valve mechanisms.

Influence of hydraulic brakes typical parameters on the process of recoiling mass breaking

open access: yesVojnotehnički Glasnik, 1998
The mathematical model for providing typical parameters of the process of breaking of recoiling mass on an artillery gun is presented. The model of hydraulic brakes with some discrete distribution of orifice surfaces in the cylinder is defined.

Radiation Loading on Pistons and Arrays of Pistons [PDF]

open access: yesThe Journal of the Acoustical Society of America, 1956
Expressions are presented whereby the radiation load on a piston or an array of pistons may be determined from physical principles and factors illustrated by various types of well-known radiating surfaces, wave guides, and conical horns. On the assumption that the radiation loading on a piston may be defined sufficiently by its low- and high-frequency ...

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 ...

Comparison of Triply Periodic Minimal Surface Energy Absorbers Under Uniaxial Compressive Loading

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates LCD 3D printed Triply Periodic Minimal Surface (TPMS) structures as mechanical energy absorbers. By comparing various base designs and layered combinations under uniaxial compression, it identifies that a Diamond‐Gyroid sandwich structure offers superior performance.
