Fast Simulation of Facilitated Spin Models

a study on thermodynamic models for simulation of 1,3 butadiene purification columns

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...

Non-equilibrium dynamics of spin facilitated glass models

We consider the dynamics of spin facilitated models of glasses in the nonequilibrium aging regime following a sudden quench from high to low temperatures. We briefly review known results obtained for the broad class of kinetically constrained models, and then present new results for the behaviour of the one-spin facilitated Fredrickson-Andersen and East models in various spatial dimensions. The...

Facilitated spin models, mode coupling theory, and ergodic–nonergodic transitions

Numerical simulation of quantum spin models.

The general application of the projector Monte Carlo method to spin systems is discussed. The purpose of the paper is to present several variants of the method that improve its accuracy and convergence in specific problems and to give numerical examples of the improvements. More detailed application to specific spin models is left for subsequent publications.

Fast Simulation of Markov Modulated Fluid Models

We consider fluid models consisting of finite buffers, constant capacities and input processes modulated by continuous time Markov chains. These models are continuous flow approximations for describing the actually discrete traffic and buffer behaviour in ATM networks. A main issue is to find good estimates of buffer overflow and loss probabilities when they are (very) small, i.e. of the order ...
