  • Optimization of stochastic dynamic system with random coefficients

    Creator:
    Yi, Man Hyung
    Abstract:
    The problem of optimization of stochastic dynamic systems with random coefficients is discussed. Systems with both Wiener processes and uncertain random-process disturbances are dealt with in this dissertation, and these include certain bilinear stochastic systems. It is the purpose of this thesis to study the optimal control and, to some...

  • Periodic Orbits and Disturbance Growth for Baroclinic Waves

    Creator:
    Samelson, R. M.
    Abstract:
    The growth of linear disturbances to stable and unstable time-periodic basic states is analyzed in an asymptotic model of weakly nonlinear, baroclinic wave–mean interaction. In this model, an ordinary differential equation for the wave amplitude is coupled to a partial differential equation for the zonal-flow correction. Floquet vectors, the eigenmodes...

  • Use of the exergy concept for design improvement of heat exchangers and heat exchanger networks

    Creator:
    Ranasinghe, Jatila
    Abstract:
    The second law of thermodynamics, through the exergy concept, allows us to quantify and rationally cost the consumption of exergy (irreversibility) used to drive the heat exchange process and the effluent losses of exergy in a heat exchanger For systems with a network of heat exchangers, the exergy concept recognizes...

  • Weighted vest exercise improves functional ability in women over 75 years of age

    Creator:
    Protiva, Karen W.
    Abstract:
    The purpose of this study was to determine the effects of long-term weighted vest exercise on hip bone mass, functional ability and static balance in elderly women. This was a within subject exercise intervention study and included a 6-month control period. Twenty-three subjects (age 85 ± 6) were recruited and...

  • Dietary riboflavin and the production of clubbed down in chick embryos

    Creator:
    Brean, Suzanne E.
    Abstract:
    Two experiments were conducted to determine the effects of riboflavin and pantothenic acid deficiency on the production of clubbed down embryos in Single Combed White Leghorn (SCWL) and Rhode Island Red (RIR) hens. In experiment 1, sixteen SCWL and eight RIR hens were assigned to one of four diets calculated...

  • Effects of maturity and blanching on carbohydrate components of frozen normal sweet (su) and supersweet (sh₂) corn

    Creator:
    Su, Shanghe
    Abstract:
    Three varieties of sweet corn (Zea mays L.) , including two supersweet (Crisp 'N Sweet 710 and Rogers 3376) and one normal sweet (Jubilee), were harvested at six stages of maturity (80-72% moisture for supersweet and 75-68% moisture for normal sweet) at three days intervals. Changes in physical and chemical...

  • Evolution of a coupled marine ice sheet-sea level model

    Creator:
    Gomez, Natalya, Pollard, David, Mitrovica, Jerry X., Huybers, Peter, and Clark, Peter U.
    Abstract:
    We investigate the stability of marine ice sheets by coupling a gravitationally self-consistent sea level model valid for a self-gravitating, viscoelastically deforming Earth to a 1-D marine ice sheet-shelf model. The evolution of the coupled model is explored for a suite of simulations in which we vary the bed slope...

  • Design of a heat exchanger network to challenge controller design methods

    Creator:
    Pashak, Jeffrey J.
    Abstract:
    A simple heat exchanger network has been studied as an example of a dynamically interactive process. The process is relatively simple, requiring only temperature measurements and flow rate manipulations. Equations are presented for the design of a physical process having a specified steady-state Relative Gain Array and specified dynamic characteristics....

  • Accelerating moderately stiff chemical kinetics in reactive-flow simulations using GPUs

    Creator:
    Niemeyer, Kyle E. and Sung, Chih-Jen
    Abstract:
    The chemical kinetics ODEs arising from operator-split reactive-flow simulations were solved on GPUs using explicit integration algorithms. Nonstiff chemical kinetics of a hydrogen oxidation mechanism (9 species and 38 irreversible reactions) were computed using the explicit fifth-order Runge–Kutta–Cash–Karp method, and the GPU-accelerated version performed faster than single- and six-core CPU...
