  • Selling and buying in a distributed virtual market place

    Creator:
    Bella, Ravi
    Abstract:
    We present a model for a distributed virtual market place that can be con­structed on the Internet to support selling and buying requests, such as those found as classified advertisements. One requirement for a transaction to take place in the virtual market place is that a sell request and a...

  • A study on the oxidation of sulfides in estuarine waters

    Creator:
    Korpalski, Thomas Paul
    Abstract:
    Waters of various salinities were secured from the Umpqua estuary, the Umpqua River, and the open ocean near the mouth of the estuary. The rate of oxidation of sulfides in these various waters was investigated to assess the potential longevity of free sulfides in estuarine waters. The rate of disappearance...

  • Spatial, diel and seasonal variations in dissolved oxygen and temperature within a stratified lake

    Creator:
    Smith, Stanley Allan
    Abstract:
    Spatial, diel and seasonal variations in dissolved oxygen and temperature were measured in Triangle Lake, Oregon. Spatial dissolved oxygen and temperature variations measured in the stratified lake are presented to illustrate the horizontal uniformity of the lake and to demonstrate the applicability of the one dimensional assumption for sampling and...

  • Modeling estuary pollution by computer simulation

    Creator:
    Grenney, William J.
    Abstract:
    A digital computer model was developed to simulate the time and space distribution of a dissolved pollutant in an estuary. The program is basically a one-dimensional finite-difference model, but two dimensions can be represented by attaching together several one-dimensional channels. The influence of convection, dispersion and decay are included in...

  • Analysis of dichotomous response models for low-dose carcinogenic risk estimation

    Creator:
    Tabesh, Taraneh
    Abstract:
    Several dichotomous-response models of carcinogenesis are discussed and their implications for low-dose risk estimation are examined. In addition, a pharmacokinetic model incorporating non-linear kinetics is studied and the results are investigated with respect to multiple-pollutant exposures. None of these models appears to suggest the existence of "thresholds". The analysis of...

  • The effect of mixing on the oxygen uptake rate of estuarine bottom deposits

    Creator:
    Martin, Duane Collins
    Abstract:
    A study of the effect of mixing on the oxygen uptake rate of estuarine bottom deposits is presented. The method of study involved the mixing of samples of bottom deposits with the overlying water to result in concentrations of suspended matter in the same order as observed in the estuary....

  • In situ measurement of the benthal oxygen requirements of tidal flat deposits

    Creator:
    Crook, Gene Ray
    Abstract:
    In situ light and dark planktonic and benthal respirometers were used to measure the oxygen requirements of Yaquina estuary water and benthal deposits. Respirometer devices were constructed so that actual conditions of mixing could be simulated and benthal deposit disturbance would be minimized. A mathematical model of a benthal respirometer...

  • Signed Digit Representation of Numbers

    Creator:
    Venkatachalapathy, Savithri
    Abstract:
    "A non-redundant number system has the digit set limited ranging from 0 to radix -1. While the Signed digit numbers have digit set consisting of more than radix r values. Hence it is also called redundant number system. Furthermore, the advantage of redundant number system lies in its application for...

  • Team Bella : reimagining character portrayals and engaging with social constructions of power in Twilight fanfiction

    Creator:
    Rost, Coral
    Abstract:
    Online fanfiction communities have received attention for providing spaces of creativity and individual empowerment. Yet as critics have sought to establish fanfiction as a worthy object of study, many have not grappled with the ways that fanfictions not only trouble, but also reinforce various discourses and ideas of gender and...

  • A token caching waiting-matching unit for tagged-token dataflow computers

    Creator:
    Traylor, Roger L.
    Abstract:
    Computers using the tagged-token dataflow model are among the best candidates for delivering extremely high levels of performance required in the future. Instruction scheduling in these computers is determined by associatively matching data-bearing tokens in a Waiting-Matching Unit (W-M unit). At the W-M unit, incoming tokens with matching contexts are...
