Interview mit Kai Nagel
Eine Verkehrssimulation ist eine Beschreibung eines komplexen Systems. Komplexe Systeme haben mich schon immer interessiert, daher habe ich auch Physik studiert. Aber in der Physik wurden die Teilchen und deren Interaktionen irgendwann so abstrakt, daß man sie vielen Menschen nicht mehr erklären konnte. Mein Interesse gilt eher Systemen, die allgemeinverständlicher darzustellen sind, z.B. sozia...
متن کاملC h d Heterogeneity of A d h h Deficiency
We report adhalin deficiency in 8 patients with clinically diagnosed muscular dystrophy, dystrophic histopathological features, high plasma creatine kinase levels, normal expression of dystrophin, and marked variability of symptoms. Although the distribution of hyposthenia was similar in all 8 patients and predominantly involved muscles in the pelvic girdle, age at onset and rate of disease pro...
متن کاملGödel, Nagel, Minds and Machines
Just fifty years ago, Ernest Nagel and Kurt Gödel became involved in a serious imbroglio about the possible inclusion of Gödel's original work on incompleteness in the book, Gödel's Proof, then being written by Nagel with James R. Newman. What led to the conflict were some unprecedented demands that Gödel made over the use of his material and his involvement in the contents of the bookdemands ...
متن کاملThe Nagel-Schreckenberg model revisited
The Nagel-Schreckenberg model is a simple cellular automaton for a realistic description of single-lane traffic on highways. For the case vmax = 1 the properties of the stationary state can be obtained exactly. For the more relevant case vmax > 1, however, one has to rely on Monte Carlo simulations or approximative methods. Here we study several analytical approximations and compare with the re...
متن کاملVelocity statistics of the Nagel-Schreckenberg model.
The statistics of velocities in the cellular automaton model of Nagel and Schreckenberg for traffic are studied. From numerical simulations, we obtain the probability distribution function (PDF) for vehicle velocities and the velocity-velocity (vv) covariance function. We identify the probability to find a standing vehicle as a potential order parameter that signals nicely the transition betwee...
