We investigate an optimal velocity car-following model for n cars on a circular singlelane road, where reaction time delay of drivers is taken into account. The stability of the uniform-flow equilibrium is studied analytically, while bifurcating periodic solutions for different wave numbers are investigated with numerical continuation techniques. This reveals that the periodic solution with the...

This article summarises three years of studying game jams. Rooted in extensive field work — participating, organising, and discussing jams multiple methods, we have explored different digital non-digital jamming formats to apply educational settings, especially the Finnish context general formal teaching for 16–19 year olds. paper sums up our main findings arranged thematically. We claim that i...

In response to sonar-guided attacking bats, some tiger moths make ultrasonic clicks of their own. The lepidopteran sounds have previously been shown to alert bats to some moths' toxic chemistry and also to startle bats unaccustomed to sonic prey. The moth sounds could also interfere with, or "jam," bat sonar, but evidence for such jamming has been inconclusive. Using ultrasonic recording and hi...

This introductory paper reviews the current state-of-the-art scientific methods used for modelling, analysing and controlling the dynamics of vehicular traffic. Possible mechanisms underlying traffic jam formation and propagation are presented from a dynamical viewpoint. Stable and unstable motions are described that may give the skeleton of traffic dynamics, and the effects of driver behaviour...

Gas and dust in inclined orbits around binaries experience precession induced by the binary gravitational torque. The difference between gas alters radial drift of weakly coupled leads to density enhancements where is minimised. We explore this phenomenon using 3D hydrodynamical simulations investigate prominence these `dust traffic jams' evolution resulting sub-structures at different disc inc...
