Dynamic experimental design

The effect of different pai ameters such as temperature, pressure, modifier volume, dynamic and static extraction time on the SFE of the plant were investigated. The orthogonal array experimental design method was chosen to determine experimental plan, (5 ). In this design the effect of five parameters and each at five levels were investigated on the extraction efficiency and selectivity [4]. [Pg.365]

As an example for precise parameter estimation of dynamic systems we consider the simple consecutive chemical reactions in a batch reactor used by Hosten and Emig (1975) and Kalogerakis and Luus (1984) for the evaluation of sequential experimental design procedures of dynamic systems. The reactions are... [Pg.202]

As a second example let us consider the fed-batch bioreactor used by Ka-logerakis and Luus (1984) to illustrate sequential experimental design methods for dynamic systems. The governing differential equations are (Lim et al., 1977) ... [Pg.207]

Our approach was demonstrated by determining multiphase flow functions from displacement experiments. Spatially resolved porosity and permeability distributions can be incorporated to mitigate errors encountered by assuming that the properties are uniform. We developed measures of the accuracy of the estimates and demonstrated improved experimental designs for obtaining more accurate estimates of the flow functions. One of the candidate experimental designs incorporated MRI measurements of saturation distributions conducted during the dynamic experiments. [Pg.382]

It is clear that one of the major challenges in the experimental studies of free radicals is the preparation of radicals. The experimental designs (production of radicals and detection of radicals and photoproducts) are largely dependent on the particular radicals of interest. Nevertheless, many approaches have been taken, as seen in this review, to study the free radical photodissociation, and a great number of systems have been examined during the last couple of years. The sophistication in the experimental studies of free radical photochemistry has reached the level that has been available for the stable molecules. State-to-state photodissociation dynamics of free radicals have been demonstrated for a few small systems. Many more advances in the field of photodissociation dynamics of radicals are expected, and it is hoped that a more systematic and sophisticated understanding of free radical photochemistry can be developed. [Pg.514]

Advances in computational capability have raised our ability to model and simulate materials structure and properties to the level at which computer experiments can sometimes offer significant guidance to experimentation, or at least provide significant insights into experimental design and interpretation. For self-assembled macromolecular structures, these simulations can be approached from the atomic-molecular scale through the use of molecular dynamics or finite element analysis. Chapter 6 discusses opportunities in computational chemical science and computational materials science. [Pg.143]

Traditionally, the progress in dynamics has been achieved by a synergetic experimental-theoretical approach where the questions which were being raised by new experimental capabilities stimulated the development of theoretical tools. In a complementary fashion, suggestions by the theory as to hitherto unexplored effects were addressed by new experimental designs. [Pg.209]

Again due to experimental design variations, the linear dynamic range varies from 102 to 1014 and also varies with the compound examined. [Pg.274]

Max Morris is a Professor in the Statistics Department and in the Department of Industrial and Manufacturing Systems Engineering at Iowa State University. His research interests include the development and application of experimental designs and strategies for computer simulations, problems involving spatial and dynamic systems, and factor screening experiments. [Pg.341]
