    A compartmental dispersion model for the analysis of mixing in tube networks (1977)
    Hoboken, NJ : Wiley-Blackwell

    Notes: A compartmental dispersion model of longitudinal mixing in tube networks has been developed. The ability of this model to predict the impulse response of helium, benzene vapor, and sulfur hexafluride tracer gases in two and in five generation symmetric network models of the large airway system of the lung has been tested over an air flow range of 1 to 400 ml/s.The results imply that velocity profile distortion and secondary flows in branching regions have only a small effect upon the overall longitudinal mixing when flow is directed toward the higher-order generations. On the other hand, accurate prediction of the data requires adequate treatment of the finite rate of evolution of the Taylor dispersion occurring in these tube networks.

    Notes: Tracer gas dispersion was measured for laminar flow through three different tube constrictions, at orifice Reynolds numbers between 10 and 5000 and Schmidt numbers of 0.213 and 0.769. Each constriction generates a confined jet which significantly enhances axial dispersion at intermediate Reynolds numbers ranging from 100 to 1000.

    Habituating control strategies for process control (1995)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 41 (1995), S. 604-618 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering

    Notes: By “reverse engineering” the functions of a specific biological system, habituating control strategies are developed for process control applications. A habituating control system has the distinguishing property of more more manipulated inputs than controlled outputs; with the inputs differing significantly in their dynamic effect on the outputs and in the relative costs of manipulating each one. A habituating controller coordinates the use of all the available inputs to achieve high-performance output objectives while simulatneously minimizing the cost of taking control action.The “baroreceptor reflex,” the control system responsible for short-term blood pressure regulation, provides the biological paradigm for the analysis and design of the habituating control structure. Its main characteristics are discussed from a process control perspective, indicating that the robust, high-performance control, characteristic of biological systems is partly due to such habituating control architectures. The broad range of potential process applications is illustrated with two examples. Two basic strategies are presented for the design of habituating controllers for linear systems with two inputs and one output: the direct synthesis approach and the model predictive approach. Compared to previous techniques for multiple-input, single-output systems, the direct synthesis strategy is straightforward and systematic. Simulation results demonstrate the superior performance of habituating control compared to conventional techniques for which the number of inputs and outputs are equal.

    Notes: The use of another air operated extreme pressure hydraulic pump fitted with either a needle valve or a simple microbore tube is described, together with the figures obtained for the soluble protein released from suspensions of commercially obtained baker's yeast (Saccharomyces cerevisiae). The theory of the mechanism is also discussed.

    Dynamics of mixed populations having complementary metabolism (1975)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: The dynamics of a system of two microbial populations having complementary metabolism are investigated by means of simple mathematical models of growth. Complementary metabolism as used here means that each population produces a substance - not present in the initial or feed medium - required by the other for growth. The simple models indicate that (1) something other than lack of the substrate or growth factor produced by its partner must limit the growth of at least one population and (2) the coexistence steady state of such populations in continuous culture is not stable with respect to large perturbations, though it is stable with respect to a wide range of perturbations.

    Notes: The salt rejection properties of cellophanes are substantially increased, and permeation rates decreased, by pretreatment with certain metal ions or presence of these ions at low concentration in feed solutions. In a typical case, a cellophane which initially rejected about 20% of salt from a 0.05M NaCl solution rejected over 70% in Presence of 10-3M ThCl4. Permeation rates were decreased, usually be a factior of 2 or 3. Additives found to have a marked effect were Fe(III), Th(IV), U(VI), Cu(II), and hydrolyzed pb(II). Mg(II), Ba(II), La(III), and unhdrolyzed Pb(II) had little effect. The mechanism by which the additives affect the cellophane is not clear.
