Microscopic insights into pedestrian motion through a bottleneck, resolving spatial and temporal variations
Jack Liddle, Armin Seyfried, Bernhard Steffen +4
The motion of pedestrians is subject to a wide range of influences and exhibits a rich phenomenology. To enable precise measurement of the density and velocity we use an alternativ…
Analysis of bottleneck motion using Voronoi diagrams
Jack Liddle, Armin Seyfried, Bernhard Steffen
Standard definitions of the density exhibit large fluctuations when the size of the measurement area is comparable with the size of a pedestrian. An alternative measurement method…
An Experimental Study of Pedestrian Congestions: Influence of Bottleneck Width and Length
Jack Liddle, Armin Seyfried, Wolfram Klingsch +3
The placement and dimensioning of exit routes is informed by experimental data and theoretical models. The experimental data is still to a large extent uncertain and contradictory.…
The deconfining phase transition in D=2+1 SU(N) gauge theories
Jack Liddle, Michael Teper
We study the deconfining transition of SU(N) gauge theories in 2+1 dimensions for N ranging between N=2 and N=8. We confirm that the transition is second order for N<4 and first or…
The spatial string tension and dimensional reduction in QCD
Bielefeld Collaboration, Jack Liddle
The spatial string tension for 3+1 dimensional QCD at finite temperature is measured. The gauge configurations we re generated with two light and one heavier strange quark on latti…
The deconfining phase transition for SU(N) theories in 2+1 dimensions
Jack Liddle, Mike Teper
The critical temperatures for the 2+1 dimensional gauge theories are calculated, for . The transition is shown to be first order for . The critic…
