Study Of Sheltered Evaporation In Colombia, Guillermo Pardo-Bonilla

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Equations, tables, and graphs for estimating evaporation from sheltered evaporimeters were developed, based on data from 20 stations in Colombia.

Computer programs and plottings were the basic tools to work out the equations. The form of the simplified final equation is

Ev = kC_VPDC_T

in which

• Ev is the evaporation in millimeters per day
• K is a constant
• C_VPD is the vapor pressure deficit coefficient
• C_T is the temperature coefficient

Statistical parameters were determined to compare the measured evaporation with the Christiansen-Guillen formula and the newly developed formulas.

Linear Programming Applied To Sheep Ranching In Utah, William R. Flint

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The study was initiated to determine how sheep ranches were physically and economically organized in 1964 and to select range and livestock management alternatives which would be profitable to sheep ranches. With data collected from the ranches three model ranches, representing the three most prominent strata, were constructed. These strata were determined by number of breeding ewes that were on the ranch and by the season of grazing on government land, i.e., winter, summer, or year around. After the building of these three ranches, each of them was linear programmed to find the profit maximizing combination of resources both before …

Systemic Studies Of The Genus Gila (Cyprinidae) Of The Colorado River Basin, Paul Bernard Holden

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three Hundred and nine specimens of Gila from the Colorado River basin were studied. A form of numerical taxonomy, taximetrics, was used to help classify the specimens. The data from these fish indicate that many of the present hypotheses concerning their taxonomy are not valid. The concept of ecosubspecies or ecological subspecies does not fit the Colorado basin Gila. The roundtail and bonytail chubs, G. robusta Baird and Girard and G. elegans Baird and Girard respectively, currently treated as subspecies, are well separated morphologically, ecologically and reproductively and therefore are better considered two valid species. The relationship between G. …

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.
