METROPOLIS network

With respect to data quality control in water, a European thematic network, METROPOLIS (2004), has identified a few typical problem areas, for example ... 

To model the fluidity of the membrane, tethers can be flipped between the two possible diagonals of two adjacent triangles. A number xjfNh of bond-flip attempts is performed with the Metropolis Monte Carlo method [173] at time intervals AtBF. where Nh = 3 Nmh - 2) is the number of bonds in the network, and 0 < yr < 1 is a parameter of the model. Simulation results show that the vertices of a dynamically triangulated membrane show diffusion, i.e., the squared distance of two initially neighboring vertices increases linearly in time.
