  • Hydrogen abstractions from arylmethanes

    Creator:
    Unruh, Jerry Dean
    Abstract:
    The relative rates of hydrogen abstraction from a series of 13 arylmethanes by the trichloromethyl radical were determined at 70°. The attacking radical was generated from bromotrichloromethane us ing benzoyl peroxide as the initiator. The solvent was benzenebromotrichloromethane. An excellent correlation, with a coefficient of 0.977, was obtained when the...

  • Dynamics and control of continuous crystallizers

    Creator:
    Leu, Lii-ping
    Abstract:
    The theoretical analysis of an unseeded, isothermal mixed-suspension mixed-product-removal (MSMPR) crystallizer with a fines trap is developed. The lumped parameter system equations are presented for a homogeneous nucleation and a number-dependent secondary-nucleation model. Linear stability analysis and system simulations are used to investigate the system's dynamic behavior. Modal control algorithms...

  • Non parametric c-sample tests for arbitrarily censored data

    Creator:
    Hirunraks, Anek
    Abstract:
    Consider the c- sample testing problem with null hypothesis H[subscript]o : F₁(x) = ... = F[subscript]c(x), where F[subscript]j(x), j = 1 ..., c, represent absolutely continuous distribution functions for failure distributions. Furthermore, consider arbitrarily (right) censored samples, which may arise from putting the (censored) experimental units on test at different...

  • Inference procedures for pairs of distributions with proportional failure rate functions

    Creator:
    McRae, Kenneth Bruce
    Abstract:
    Some nonparametric maximum likelihood estimation procedures are developed for the class of pairs of distributions which have proportional failure rate functions. Special consideration is given to the case in which the shape of the failure rate functions are assumed to be either increasing or decreasing. Estimators of the proportionality constant,...

  • Goodness of fit tests under random censorship

    Creator:
    Chen, Jiin-chiang
    Abstract:
    The classical chi-square goodness of fit test and the Neyman smooth tests are generalized for arbitrarily right-censored samples. The test statistics are shown to have limiting chi-square distributions under completely specified (simple) null hypotheses and random censorship. Limiting distributions of the generalized chi-square goodness of fit tests are also established...

  • Statistical estimation for initiative petitions and performance of the decision rule for Oregon state petitions

    Creator:
    Smith-Cayama, Rubén A.
    Abstract:
    Two topics concerning statistical sampling of initiative petitions are considered in this dissertation. The first concerns statistical estimation of the number of distinct valid signatures in a petition, and the second evaluates the statistical decision rule used by Oregon for determining certification of state initiative and referendum petitions. In several...

  • Bootstrap prediction and tolerance intervals for the Weibull regression model with censored data

    Creator:
    Abdelhafez, Mohamed Elwy Mahran
    Abstract:
    The problems of constructing prediction and tolerance intervals were considered for Weibull regression models. On the extreme value distribution scale, the models have the linear form y = Xβ + σ z , =NM where y is the transformed random response vector, X is the nxq matrix containing values of...
