Accuracy limitations and the measurement of errors in the stochastic simulation of chemically reacting systems
This paper introduces the concept of distribution distance for the measurement of errors in exact and approximate methods for stochastic simulation of chemically reacting systems. Two types of distance are discussed: the Kolmogorov distance and the histogram distance. The self-distance, an important property of Monte-Carlo methods that quantifies the accuracy limitation at a given resolution fo...
متن کاملChemically-resolved aerosol volatility measurements from two megacity field studies
The volatilities of different chemical species in ambient aerosols are important but remain poorly characterized. The coupling of a recently developed rapid temperature-stepping thermodenuder (TD, operated in the range 54–230C) with a High-Resolution Time-of-Flight Aerosol Mass Spectrometer (HR-ToF-AMS) during field studies in two polluted megacities has enabled the first direct characterizatio...
متن کاملParallel studies for chemically reacting systems
Parallel computing code can be applied to solve chemically reacting systems. In a well stirred chemical system, the number of molecules for each species can be solved by implicit tau method, and the histogram of the method is used to compare with the exact simulation called SSA. In this report, the parallel code will be implemented in both SSA and implicit tau, with the discussion that how rand...
متن کاملApproximate Stochastic Models for Chemically Reacting Systems
In the stochastic formulation of chemical reactions, the time evolution of the first M order statistical moments for the number of molecules of the different species involved is generally not closed, in the sense that they depend on moments of order higher than M. For analysis purposes, the time evolution of the first M order moments is often made to be closed by approximating the higher order ...
