Journal ArticleDOI
Nitric/Nitrous Acid Equilibria in Supercritical Water
TL;DR: In this paper, the extinction coefficients of aqueous HNO3 solutions were derived from individual bands corresponding to HNO2 and NO2 up to 400 °C with constrained nonlinear optimization.
Book ChapterDOI
A Multistart Scatter Search Heuristic for Smooth NLP and MINLP Problems
TL;DR: The algorithm described here, called OptQuest/NLP or OQNLP, is a heuristic designed to find global optima for pure and mixed integer nonlinear problems with many constraints and variables, where all problem functions are differentiable with respect to the continuous variables.
Journal ArticleDOI
Piece-by-piece approach to solving large nonlinear water resources management models
TL;DR: This work applies the piece-by-piece method to a large multiperiod nonlinear programming (NLP) model with 13,700 variables, 10,000 equations, and a high degree of nonlinearity (54.3% of the nonzero Jacobian elements are nonconstant), arising from water resources planning and operation in a river basin.
Journal ArticleDOI
A generalized upper bounding algorithm for multicommodity network flow problems
James K. Hartman,Leon S. Lasdon +1 more
TL;DR: An algorithm for solving min cost or max flow multicommodation flow problems is described, a specialization of the simplex method, which takes advantage of the special structure of the multicommodity problem.
Journal ArticleDOI
Modeling and Resolution of the Medium Term Energy Generation Planning Problem for a Large Hydro-Electric System
TL;DR: This paper is concerned with the modeling and resolution of the energy generation planning problem of a large hydroelectric system for a horizon up to two years, with emphasis on hydro plant generation, hydro system aggregation, and objective function modeling.
