Spurious phase in a model for traffic on a bridge
David W. Erickson, Gunnar Pruessner, B. Schmittmann +1
We present high-precision Monte Carlo data for the phase diagram of a two-species driven diffusive system, reminiscent of traffic across a narrow bridge. Earlier studies reported t…
Fluctuations and Correlations in Lattice Models for Predator-Prey Interaction
Mauro Mobilia, Ivan T. Georgiev, Uwe C. Tauber
Including spatial structure and stochastic noise invalidates the classical Lotka-Volterra picture of stable regular population cycles emerging in models for predator-prey interacti…
Growth of relatively hyperbolic groups
Xiangdong Xie
We show that a relatively hyperbolic group either is virtually cyclic or has uniform exponential growth.
Will jams get worse when slow cars move over?
B. Schmittmann, J. Krometis, R. K. P. Zia
Motivated by an analogy with traffic, we simulate two species of particles (`vehicles'), moving stochastically in opposite directions on a two-lane ring road. Each species prefers…
Local and Global Analysis: Complementary Activities for Increasing the Effectiveness of Requirements Verification and Validation
Lester Lobo, James D. Arthur
This paper presents a unique approach to connecting requirements engineering (RE) activities into a process framework that can be employed to obtain quality requirements with reduc…
Anomalous nucleation far from equilibrium
Ivan T. Georgiev, Beate Schmittmann, Royce K. P. Zia
We present precision Monte Carlo data and analytic arguments for an asymmetric exclusion process, involving two species of particles driven in opposite directions on a …
