Characteristic of Bennett’s acceptance ratio method

open access: yesPhysical Review E, 2009
A powerful and well-established tool for free-energy estimation is Bennett's acceptance ratio method. Central properties of this estimator, which employs samples of work values of a forward and its time reversed process, are known: for given sets of measured work values, it results in the best estimate of the free-energy difference in the large sample ...

The Dual Characteristic-Galerkin Method

open access: yesComptes Rendus. Mathématique
The Dual Characteristic-Galerkin method (DCGM) is conservative, precise and experimentally positive. We present the method and prove convergence and $L^2$-stability in the case of Neumann boundary conditions. In a 2D numerical finite element setting (FEM)

Determination of traffic flow parameters in different traffic flow interaction cases [PDF]

open access: yesTransport, 2007
Modelling of straight road section consisting of one traffic line gives the opportunity to simulate “follow the car” system. In general it looks like a line of vehicles, going one after another.

The existence and uniqueness of solutions of a nonlinear toxin-dependent size-structured population model

open access: yesMathematics in Applied Sciences and Engineering, 2022
In this paper, we study a toxin-mediated size-structured population model with nonlinear reproduction, growth, and mortality rates. By using the characteristic method and the contraction mapping argument, we establish the existence-uniqueness of ...
