Tests Of Methods That Control Round-Off Error, Dale M. Rasmuson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Methods of controlling round-off error in one-step methods in the numerical solution of ordinary differential equations are compared. A new Algorithm called theoretical cumulative rounding is formulated. Round-off error bounds are obtained for single precision, and theoretical cumulative rounding. Limits of these bounds are obtained as the step length approaches zero. It is shown that the limit of the bound on the round-off error is unbounded for single precision and double precision, is constant for theoretical partial double precision, and is zero for theoretical cumulative rounding.

The limits of round-off bounds are not obtainable in actual practice. The round-off error …

Algebraic Properties Of Endomorphisms Of Abelian Groups And Rings, Johnnie George Slagle

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The main objective of the thesis was to extend the definition of an M-Group to what is called an M-Ring. From this extension a system called an expanded ring follows naturally. To facilitate the development of the expanded ring, chapter I is devoted to developing properties on systems that are not quite rings where many interesting examples are constructed. In chapter II the definition of an M-Ring is given and some of its properties are derived. In chapter III some of the properties of expanded rings are proved, and examples of expanded rings are given to show their existence.

The Value Of A Trout Stream Fishery, Archie Allen Dyer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The data analysis indicated that travel distance, user age, and user income level are important determinants of use of trout streams.

These variables were incorporated into regression analysis to develop a use-prediction model.

This use-prediction model was used to determine predicted use levels of sample streams. The predicted use levels combined with travel costs and expenditures on new fishing equipment were used to derive a statistical estimate of the demand schedules for the sample streams.

These statistical demand curves were subjected to consumer surplus procedures to determine the values of the sample streams.

A Study Of Input-Output Adjustments, Charles W. Briggs

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effects of using the United States input-output table to explain Israel's economic structure was studied, by comparing price data generated on the basis of the U. S. tables and prices observed in the two countries. A substantial difference between prices generated and observed led to the conclusion that the technological structure of the United States cannot be used to approximate Israel's structure.

Various adjustments were then applied to the United States coefficient matrix to determine if it could be transformed into a new technological structure which would more closely approximate Israel's economy.

Significant improvements were noted by three of …

An Investigation Of Methods For Estimating Marginal Values Of Irrigation Water, Richard L. Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Marginal values of water used in irrigation are needed if water is to be optimally allocated among alternative uses. Cobb-Douglas production function analysis and linear programming methods were studied in this investigation to find their fruit-fulness in predicting these marginal values. The theoretical properties of both methods indicate that they are conceptually capable of yielding valid marginal value estimates for irrigation water.

Further investigation of the two methods was carried out as an empirical test in the Milford area of Utah. Marginal values of water used for irrigation in that area were estimated by both procedures. Although inviolable criteria for …

Experiments On The Inactivation Of Zinc By The Mineral Fractions Of The Soil, John J. Hassett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Zinc deficiency, in many cases, is closely related to organic matter decomposition. DeRemer and Smith (1964) studied the effects of decomposing sugar beet tops on the reactions of Zn⁶⁵ in a Portneuf soil. They found that with time the Zn⁶⁵ associated with lime minerals, exchangeable, and water soluble fractions of the soil decreased, while that found with the organic and mineral fractions increased. This increase in the mineral fraction is of particular interest, since the majority of the Zn⁶⁵ was found to be with this fraction after a period of time. They also showed that the increase …

A Study Of The Natural Rubber Industry, With Special Reference To Thailand, Suratana Vayagool

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relative share of natural rubber in the world's total rubber consumption had been decreasing from 75 percent in 1948- 1949 to 44.4 percent in 1965. Since the production of natural rubber has been rising over the same period, some predictions have been made indicating that there will be a surplus of production over consumption of natural rubber in the near future.

In the world output of natural rubber industry, Thailand ranks third, being surpassed only by Malaysia and Indonesia. Of all the exports of Thailand, rubber ranks second in value and is exceeded only by rice. Almost all of …
