Simulation of High Density Pedestrian Flow: Microscopic Model [PDF]

open access: yes, 2015
In recent years modelling crowd and evacuation dynamics has become very important, with increasing huge numbers of people gathering around the world for many reasons and events.

Microscopic Models for Chemical Thermodynamics [PDF]

open access: yesJournal of Statistical Physics, 2005
We introduce an infinite particle system dynamics, which includes stochastic chemical kinetics models, the classical Kac model and free space movement. We study energy redistribution between two energy types (kinetic and chemical) in different time scales, similar to energy redistribution in the living cell.

Development of a Pedestrian Capacity Using a Movement Simulation Model in Malioboro, Yogyakarta, Indonesia

open access: yesASM Science Journal, 2022
The activity of pedestrian movement can be predicted by a pedestrian model. Pedestrian model would assign pedestrian lane characteristic, especially for capacity.

A Microscopic Heterogeneous Traffic Flow Model Considering Distance Headway

open access: yesMathematics, 2022
The intelligent driver (ID) model characterizes traffic behavior with a constant acceleration exponent and does not follow traffic physics. This results in unrealistic traffic behavior. In this paper, a new microscopic heterogeneous traffic flow model is

A combined mathematica--fortran program package for analytical calculation of the matrix elements of the microscopic cluster model [PDF]

open access: yesComput.Phys.Commun. 104 (1997) 259-274, 1993
We present a computer code that analytically evaluates the matrix elements of the microscopic nuclear Hamiltonian and unity operator between Slater determinants of displaced gaussian single particle orbits. Such matrix elements appear in the generator coordinate model and the resonating group model versions of the microscopic multicluster calculations.

Capillarity of soft amorphous solids: a microscopic model for surface stress. [PDF]

open access: yesPhysical review. E, Statistical, nonlinear, and soft matter physics, 2013
The elastic deformation of a soft solid induced by capillary forces crucially relies on the excess stress inside the solid-liquid interface. While for a liquid-liquid interface this "surface stress" is strictly identical to the "surface free energy," the

Derivation of the Boltzmann Equation for Financial Brownian Motion: Direct Observation of the Collective Motion of High-Frequency Traders [PDF]

open access: yesPhys. Rev. Lett. 120, 138301 (2018), 2017
A microscopic model is established for financial Brownian motion from the direct observation of the dynamics of high-frequency traders (HFTs) in a foreign exchange market. Furthermore, a theoretical framework parallel to molecular kinetic theory is developed for the systematic description of the financial market from microscopic dynamics of HFTs.

Congested traffic states in empirical observations and microscopic simulations [PDF]

open access: yesPhysical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 2000
We present data from several German freeways showing different kinds of congested traffic forming near road inhomogeneities, specifically lane closings, intersections, or uphill gradients. The states are localized or extended, homogeneous or oscillating.
