Lateral Deflections And Stress Analysis Of Plate Girder Webs Subjected To Horizontal Loads, Hong-To Lam

Electronic Theses and Dissertations

In a routine design of a plate girder bridge, the structural engineer is mainly concerned with the gross area of the flange due to bending and the gross area of the web due to shear. The web deflections and stresses due to horizontal loads resulting from the bracket during construction are not considered. The object of this thesis is to establish a mathematical solution which permits the prediction of structural behavior of the web for lateral loads. The web deflection and stress which occur as a result of using temporary construction brackets are primarily studied. In this investigation, a partial …

Vulnerability Analysis Of Two Water Treatment Utilities To The Effects Of Fallout Contamination, Richard R. Bell

Electronic Theses and Dissertations

The general objective of this study was to determine the vulnerability to the effects of nuclear detonation of two selected representative water treatment utilities in order to assess the overall preparedness of South Dakota Water utilities. Some specific questions of the investigation were these:
1) Is adequate protection from radioactivity available in the area of the treatment plant for the operators to function safely during a fallout period? Could the operators continue to operate the plant?
2) Will the source of water yield uncontaminated water during a fallout period?
A. Can an adequate source of water be derived from a …

A Study Of The Properties Of Parametric Programming, Arjun Kumar Batr

Electronic Theses and Dissertations

Programming is defined as the planning of activities for the sake of optimization. When linear constraints are ·assumed, together with a linear objective function, the optimization is defined as solving a linear programming problem. Linear programming was originally developed by Dantzig, Wood and (others for the U.S. Air Force. Since it was first published in 1947, it has been used widely in industrial as well as military situations.

Examples of specific exotic and straight forward applications of the linear programming technique can be found in text books, monographs and technical papers in the several fields in which it has been …

Classification Error Of Gaussian And Transformed Gaussian Variates, John E. Boyd

Electronic Theses and Dissertations

As indicated by the title and by the large proportion of pages devoted to the subject, transformation of variables is the primary topic of this thesis. The transformation of partially overlapping, correlated, two-dimensional, Gaussian distributed random variates to partially overlapping, independent, one-dimensional, Cauchy distributed random variates involves a reduction in dimensionality by one. Consequently, the equation defining the receiver is simplified, and the expressions for predicting the classification error are easier to formulate. The equation required to effect this transformation is z=Y₁/Y₂ , where Y₁ , Y ₂ are the standardized correlated Gaussian variates and z …

Analysis Of The Phase-Angle Method When Applied To An Actual Power System, Neal D. Drefke

Electronic Theses and Dissertations

Determining the optimum generation schedule for a power system has been a basic problem in the electrical power industry for many years. The computations needed to determine the optimum generation schedule are becoming more complex and the need for greater accuracy increases, for a percentage savings represents total dollar savings on the ever-growing power systems. The most accurate method for determining the optimum generation schedule has come to be known as the phase-angle method. This method gives an optimum generation schedule for minimum fuel input where the fuel input is expressed in monetary units per unit of time. The only …

Partial Cooling Of The Environment In Free Stalls For Sows During Farrowing And Lactation, Thomas R. Gannon

Electronic Theses and Dissertations

Many of the technological advances in the swine industry have resulted in increased capital requirements for buildings and equipment. This has made multiple farrowing, including summer farrowing, a near necessity. Hog farmers recognize the problem of sow mortality due to severe heat stress during periods of high ambient temperatures, and hog producers utilizing the free stall farrowing system recognize yet another problem, that of poor stall occupancy. Sows in this type of system tend to seek relief by leaving their stalls and lying in moist or breezy areas. This decreased stall occupancy has resulted in pigs being severely neglected, reduced …

Selected Physiological Changes In College Men And Women Participating In Social Dance, Barbara Dale Bovee

Electronic Theses and Dissertations

The purpose of this investigation was to study the physiological effects of social dance on selected bodily responses of freshman male and female students at South Dakota State University. The selected bodily responses investigated were dynamic balance, static balance, trunk flexibility, agility, leg power, and leg strength.

Prediction Of Beef Palatability Factors And Relationships Between Live And Carcass Traits, Richard J. Berns

Electronic Theses and Dissertations

The agricultural industry or South Dakota is primarily based on the beer cow and her products. Cattle feeders had 275, 000 head of cattle and calves on feed on July 1, 1970, a 2 percent increase over July 1, 1969. South Dakota has about 1, 719, 000 beef cows which is 38 percent more than a decade ago. The state can continue to increase beef production in many ways such as retaining mare cows to produce feeders, increasing calving percentage, using crossbreeding, or feeding cattle to heavier weights. Increased carrying capacity through irrigation and management may be another avenue to …

A Theoretical Investigation Of Shock Wave Stability In Sonic Inlets, Assem A. Fathy

Electronic Theses and Dissertations

A theoretical investigation of the shock wave stability applicable to "sonic" and supersonic inlets is presented. It is assumed that the boundary layer remains attached and that the principal sources of instability are the acoustic wave reflections from the shock wave and the face. The analysis is based on linearized one-dimensional flow theory and involves the solution of the wave equation with variable coefficients. The solution is obtained by series expansion. The results suggest that shock stability is mainly dependent on the shock strength and to a certain extent on the area distribution. For a given geometry, increasing the shock …

Fracture Initiation In Viscoelastic Solids, James A. Elsing

Electronic Theses and Dissertations

The subject of this paper is to derive generalized analytical expressions to predict fracture in viscoelastic polymer materials. To aid in understanding behavioral characteristics of viscoelastic materials, a basic background of viscoelastic models and their responses are presented and briefly discussed. Fracture from two types of cracks are considered; the first 1s a penny-shaped crack in a three-dimensional solid and the second is a crack the thickness of the material in a two-dimensional solid. Except for the constants, the same equations describe fracture in both 2-D and 3-D solids. The fracture equations were developed using expressions from Sneddon, Wnuk, Griffith …
