Since the 2005 demonstration of optimal topological chaos in a particular instance of the 2-sector RSS model, the delineation of the optimal policy function for “small” discount factors has remained open. This paper (i) provides an explicit solution when the discount factor is less than the labor/capital-output ratio, (ii) establishes the existence of optimal topological chaos for a non-negligi...

An analytical equation of state by Song and Mason is developed to calculate the PVT properties ofmercury. The equation of state is based on the statistical-mechanical perturbation theory of hard convexbodies and can be written as a fifth-order polynomial in the density. There exists three temperaturedependentparameters in the equation of state; the second virial coefficient, an effective molecu...

Carbon capture and storage (CCS) has attracted renewed interest in the re-evaluation of equations state (EoS) for prediction thermodynamic properties. This study also evaluates EoS Peng–Robinson (PR) Soave–Redlich–Kwong (SRK) their capability to predict properties CO2-rich mixtures. The investigation was carried out using machine learning such as an artificial neural network (ANN) a classified ...

New isothermal vapor–liquid equilibrium (VLE) data for the carbon dioxide + 1,4-dioxane system are reported at four temperatures (323.15, 333.15, 343.15, and 353.15) K pressures up to 122.7 bar. The critical curve was also measured 158.8 bar 420.15 K. Phase behavior measurements were performed in a high-pressure windowed cell with variable volume, using static-analytical method phases sampling ...

Modeling of the relationship between the pressure and yield of biomaterials is an essential issue in supercritical fluid extraction. In this paper, neural networks are proposed for modeling of supercritical fluid extraction. First a three-layer neural network with a fast learning algorithm is used, and its performance is compared to a conventional model of the Peng-Robinson equation of state. A...

The present work is the successful extension of an improved equation of state (EOS) to refrigerant fluids. The objective is the prediction of isothermal and saturated liquid densities of refrigerants. Two temperature-independent parameters appearing in the modified EOS are closely related to critical point properties of refrigerant fluids. Our results showed that, the proposed EOS can predict w...

the simplified perturbed chain statistical associating fluid theory (spc-saft) equation of state (eos) was proposed to describe the thermodynamic properties of pure ionic liquids (ils). a set of spc-saft parameters for 2 ils was obtained by fitting the experimental liquid densities data over a wide range of temperature at atmospheric pressure. good agreement with experimental density data was o...
