Optimization and homotopy methods for the Gibbs free energy of simple magmatic mixtures
Cassioli, A.; Consolini, L.; Locatelli, M.; Longo, A. - In: Computational Optimization and Applications 55 (2013) 2, pp. 427-457
In this paper we consider a mathematical model for magmatic mixtures based on the Gibbs free energy. Different reformulations of the problem are presented and some theoretical results about the existence and number of solutions are derived. Finally, two homotopy methods and a global optimization...

The thermodynamic properties of the upper continental crust: Exergy, Gibbs free energy and enthalpy
Valero, Alicia; Valero, Antonio; Vieillard, Philippe - In: Energy 41 (2012) 1, pp. 121-127
This paper shows a comprehensive database of the thermodynamic properties of the most abundant minerals of the upper continental crust. For those substances whose thermodynamic properties are not listed in the literature, their enthalpy and Gibbs free energy are calculated with 11 different...

Hierarchy of equations for reduced density matrices in the case of thermodynamic equilibrium
Golovko, V.A. - In: Physica A: Statistical Mechanics and its Applications 230 (1996) 3, pp. 658-702
A hierarchy of equations for s-particle density matrices at thermodynamic equilibrium is obtained, with the equation for the nonequilibrium density matrix as the starting point. When deducing the hierarchy the hypothesis of maximum statistical independence for the density matrices is used. The...

Biomass power for rural development. Quarterly report, July 1--September 30, 1998
Cooper, J.T. - 2008
In this quarter a large amount of time was spent doing project planning and budget preparation for the fiscal years 1998 and 1999. Many issues of long-term strategic planning and budgeting depend on the availability of Federal support, including financial, technical and political. It has become...

Development of an advanced, continuous mild gasification process for the production of co-products
Cohen, L.R.; Hogsett, R.F.; Sinor, J.E.; Ness, R.O. Jr.; … - 2008
The principal finding of this study was the high capital cost and poor financial performance predicted for the size and configuration of the plant design presented. The XBi financial assessment gave a disappointingly low base-case discounted cash flow rate of return (DCFRR) of only 8.1% based on...

Substitute Natural Gas Feasibility Study
Henward, Howard - 2008
High natural gas prices and domestic energy security concerns have led to a resurgent interest in substitute natural gas (SNG). This technology, which dates back several decades, is currently only utilized in one location in the U.S., though perhaps a dozen more are on the drawing board. This...
