Evaluation of Static and Dynamic Characteristics of Bump Metal Mesh Foil Bearing
Tribology OnlineGas foil bearings, which are oil-free and exhibit low energy losses, are used in high-speed rotating machinery. Because gas is used as the working fluid, there is a need to improve damping performance using support structures.

Morphology Scaling of Drop Impact onto a Granular Layer
, 2010 We investigate the impact of a free-falling water drop onto a granular layer. First, we constructed a phase diagram of crater shapes with two control parameters, impact speed and grain size.

Rossby Wave Instability and three-dimensional vortices in accretion disks [PDF]
, 2010 Context. The formation of vortices in accretion disks is of high interest in various astrophysical contexts, in particular for planet formation or in the disks of compact objects. But despite numerous attempts it has thus far not been possible to produce

Moving bumps in theta neuron networks
, 2020 We consider large networks of theta neurons on a ring, synaptically coupled with an asymmetric kernel. Such networks support stable "bumps" of activity, which move along the ring if the coupling kernel is asymmetric.

Evolution of populations expanding on curved surfaces [PDF]
, 2018 The expansion of a population into new habitat is a transient process that leaves its footprints in the genetic composition of the expanding population. How the structure of the environment shapes the population front and the evolutionary dynamics during

Detailed Structure and Dynamics in Particle-in-Cell Simulations of the Lunar Wake [PDF]
, 2001 The solar wind plasma from the Sun interacts with the Moon, generating a wake structure behind it, since the Moon is to a good approximation an insulator, has no intrinsic magnetic field and a very thin atmosphere.

Effect of suspension systems on the physiological and psychological responses to sub-maximal biking on simulated smooth and bumpy tracks [PDF]
, 2006 The aim of this study was to compare the physiological and psychological responses of cyclists riding on a hard tail bicycle and on a full suspension bicycle. Twenty males participated in two series of tests. A test rig held the front axle of the bicycle

Research on Detection of Multiple Types of Speed Bump Defects Based on CRSCCG-YOLOv5s
IEEE AccessSpeed bumps, as a crucial road safety infrastructure, can directly impact the accident rates on specific road sections if they have defects. Therefore, this study proposes a method for detecting speed bump multiclass defects using an improved YOLOv5s ...

Coarse-grained dynamics of an activity bump in a neural field model
, 2006 We study a stochastic nonlocal PDE, arising in the context of modelling spatially distributed neural activity, which is capable of sustaining stationary and moving spatially-localized ``activity bumps''.
