Traffic and related self-driven many-particle systems

by Dirk Helbing , 2000
"... Since the subject of traffic dynamics has captured the interest of physicists, many surprising effects have been revealed and explained. Some of the questions now understood are the following: Why are vehicles sometimes stopped by ‘‘phantom traffic jams’ ’ even though drivers all like to drive fast? ..."

micro-macro link, to aspects of universality, and to other unifying concepts, such as a general modeling framework for self-driven many-particle systems, including spin systems. While the primary focus is upon vehicle and pedestrian traffic, applications to biological or socio-economic systems

Phase transitions in self-driven many-particle systems and related non-equilibrium models: a network approach

by Maximino Aldana, Cristián Huepe - Journal of Statistical Physics, 112(1/2):135-153. [doi:10.1023/A:1023675519930] Breder, C.M , 2003
"... We investigate the conditions that produce a phase transition from an ordered to a disordered state in a family of models of two-dimensional elements with a ferromagnetic-like interaction. This family is defined to contain under the same framework, among others, the XY-model and the Self-Driven Part ..."

qualitatively equivalent phase transition appears whenever even a small amount of long-range interactions are present (or built over time), regardless of other equilibrium or non-equilibrium proper-ties of the system. KEY WORDS: Phase transition; self-driven particles; vectorial network. 1.

Traffic Experiment Reveals the Nature of Car-Following

by Rui Jiang, Mao-bin Hu, H. M. Zhang, Zi-you Gao, Bin Jia, Qing-song Wu, Bing Wang, Ming Yang , 2014
"... As a typical self-driven many-particle system far from equilibrium, traffic flow exhibits diverse fascinating non-equilibrium phenomena, most of which are closely related to traffic flow stability and specifically the growth/dissipation pattern of disturbances. However, the traffic theories have bee ..."

OF SELF-DRIVEN PARTICLES

by Tamás Vicsek, B András Czirók, A Eshel Ben-jacob, C Inon Cohen, Ofer Shochet , 2006
"... A simple model with a novel type of dynamics is introduced in order to investigate the emergence of self-ordered motion in systems of particles with biologically motivated interaction. In our model particles are driven with a constant absolute velocity and at each time step assume the average direct ..."

A tutorial on particle filters for online nonlinear/non-Gaussian Bayesian tracking

by M. Sanjeev Arulampalam, Simon Maskell, Neil Gordon - IEEE TRANSACTIONS ON SIGNAL PROCESSING , 2002
"... Increasingly, for many application areas, it is becoming important to include elements of nonlinearity and non-Gaussianity in order to model accurately the underlying dynamics of a physical system. Moreover, it is typically crucial to process data on-line as it arrives, both from the point of view o ..."

Static Scheduling of Synchronous Data Flow Programs for Digital Signal Processing

by Edward Ashford Lee, David G. Messerschmitt - IEEE TRANSACTIONS ON COMPUTERS , 1987
"... Large grain data flow (LGDF) programming is natural and convenient for describing digital signal processing (DSP) systems, but its runtime overhead is costly in real time or cost-sensitive applications. In some situations, designers are not willing to squander computing resources for the sake of pro ..."

special case of Petri nets. This self-contained paper develops the theory necessary to statically schedule SDF programs on single or multiple proces-sors. A class of static (compile time) scheduling algorithms is proven valid, and specific algorithms are given for scheduling SDF systems onto single

Earthquake Shakes Twitter Users: Real-time Event Detection by Social Sensors

by Takeshi Sakaki, Makoto Okazaki, Yutaka Matsuo - In Proceedings of the Nineteenth International WWW Conference (WWW2010). ACM , 2010
"... Twitter, a popular microblogging service, has received much attention recently. An important characteristic of Twitter is its real-time nature. For example, when an earthquake occurs, people make many Twitter posts (tweets) related to the earthquake, which enables detection of earthquake occurrence ..."

The particle filter works better than other compared methods in estimating the centers of earthquakes and the trajectories of typhoons. As an application, we construct an earthquake reporting system in Japan. Because

Integration of the cognitive and the psychodynamic unconscious

by Seymour Epstein - American Psychologist , 1994
"... Cognitive-experiential self-theory integrates the cognitive and the psychodynamic unconscious by assuming the ex-istence of two parallel, interacting modes of information processing: a rational system and an emotionally driven experiential system. Support for the theory is provided by the convergenc ..."

Practical animation of liquids

by Nick Foster, Dimitri Metaxas - Graphical Models and Image Processing , 1996
"... We present a comprehensive methodology for realistically animating liquid phenomena. Our approach unifies existing computer graphics techniques for simulating fluids and extends them by incorporating more complex behavior. It is based on the Navier-Stokes equations which couple momentum and mass con ..."

Particle Systems - A Technique for Modeling a Class of Fuzzy Objects

by William T. Reeves - ACM Transactions on Graphics , 1983
"... This paper introduces particle systems--a method for modeling fuzzy objects such as fire, clouds, and water. Particle systems model an object as a cloud of primitive particles that define its volume. Over a period of time, particles are generated into the system, move and change form within the syst ..."
