An Investigation of Influence of Windshield Configuration and Train Length on High-Speed Train Aerodynamic Performance [PDF]
Journal of Applied Fluid Mechanics, 2022 The aerodynamic performance of four train models with different windshield configurations (i.e., internal and/or external) in three train marshalling modes (i.e., 3, 6 and 8-car groups) was numerically investigated in this study.

Regional distribution of transpulmonary pressure [PDF]
Annals of Translational Medicine, 2018 The pressure across the lung, so-called transpulmonary pressure (PL), represents the main force acting toward to provide lung movement. During mechanical ventilation, PL is provided by respiratory system pressurization, using specific ventilator setting settled by the operator, such as: tidal volume (VT), positive end-expiratory pressure (PEEP ...

Pressure distribution on spline couplings [PDF]
EPJ Web of Conferences, 2010 Spline couplings are mechanical devices commonly used to join two shafts. Accordingly to the type of spline (straight teeth, crowned teeth, etc ) and gap between the teeth, joined shafts may have certain positioning errors, as misalignments or inclinations.

Diffusion, Peer Pressure, and Tailed Distributions [PDF]
Physical Review Letters, 2002 We present a general, physically motivated non-linear and non-local advection equation in which the diffusion of interacting random walkers competes with a local drift arising from a kind of peer pressure. We show, using a mapping to an integrable dynamical system, that on varying a parameter, the steady state behaviour undergoes a transition from the ...

Microhardness Distribution of Long Magnesium Block Processed through Powder Metallurgy
Journal of Manufacturing and Materials Processing, 2022 Powder metallurgy is a popular method of making raw powders into specific shaped samples. However, the pressure distribution and the microhardness difference within the sample are nonnegligible and unclear when the sample is long or exceeds a specific ...
