A Logistic System Simulation Model Encompassing Poisson Processes And Normal Or Weibull Life, Willard A. Hansen
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This thesis describes a computer simulation model for determining effective spares stock levels for recoverable items at Air Force bases and depots. The simulation model is based on the following fundamental inventory theory; whenever a demand arises, it is satisfied from stock on hand, and the quantity equal to that demand is recorded immediately; when a demand exceeds stock on hand, the excess demand is backordered immediately and when item life expires procurement action is initiated at depot level. The resulting product of the model cam be used as a guide for the optimum distribution of available spares or as …

A Monte Carlo Study Of Non-Linear Regression Theory, Ya-Ming Liu
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Multiple regression provides the capability of using non-linear functions to fit various curvilinear surfaces. These non-linear functions are, however, linear in the parameters. Non-linear term of the variables such as X2, X3, ln X, X, YX are incorporated in a linear model. For example:
Y = b0 + b1 x1 + b2 x12 + b3 lnx2 + ϵ
Many practical situations require the fitting of mathematical functions which are non-linear in the parameters and perhaps the variables. For example:
Y = b, eb2X + ϵ

The Course Or Behavior Of Applied Zinc To Soil Containing Different Levels Of Freshly Applied Organic Matter, Artnel Samuel Henry
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Soil organic matter consists of a heterogenous mixture of plant, animal, and microbial material in various stages of decomposition. It possesses characteristics which at present are not very well known. Careful studies have been directed towards the behavior of organic matter as it affects plants directly and man indirectly. Consequently, much tire is devoted to its study from the point of metal inactivation and chelation, the earlier investigations failed to produce results worthy of the efforts expended, so a loss of interest in the continued pursuit of knowledge resulted, about two decades ago when it was learned that many polyvalent …

A monopolist, knowing the demand curve for his product, can in a given period produce the quantity of this product which will maximize his profit. Any larger or smaller quantity will result in less profit. When another manufacturer starts producing the same or similar product, a duopoly result. The new manufacturer, in order to maximize his profit, according to Cournot, will choose a quantity that is derived on the assumption that the original manufacturer's quantity will remain fixed.

Stage-Fall-Discharge Relations For Flood Flows Over Highway Embankments, Gaylord V. Skogerboe, M. Leon Hyatt, Lloyd H. Austin
Reports
At Utah State University, considerable effort has been devoted to the analysis of submerged flow at open channel constrictions. A method of analyzing submerged flow was first developed for a trapezoidal flume by Hyatt (1965). Later studies verified the method of analysis for a rectangular flume (Skogerboe, Walker, and Robinson, 1965) and Parshall flumes (Skogerboe, Hyatt, England, and Johnson, 1965). Because of the previous findings, it was felt this method of analyzing submerged flow could be applied to highway embankments.
A highway embankment is a form of broad-crested weir when overtopped by flood waters. Being a weir, the flood discharge …

Measuring Water With Parshall Flumes, Gaylord V. Skogerboe, M. Leon Hyatt, Joe D. England, J. Raymond Johnson
Reports
Preface: As the value of water increases, the extent to which measurement is employed in an irrigation system also increases. Additional flow measurements provide information for improved management of the water supply. Good water management requires accurate measurement. Many devices have been developed for this purpose and are in use. Included among them are weirs, orifices, calibrated gates, Parshall flumes, and current meters. Of these, the Parshall flume is one of the most widely accepted and used. Presented in this publication is a discussion concerning the use of Parshall flumes for measuring water, including the utilization of a new approach …

Subcritical Flow Over Various Weir Shapes, M. Leon Hyatt, Gaylord V. Skogerboe, Lloyd H. Austin
Reports
Submerged flow exists for any given structure when a change in flow depth downstream from the structure causes a change in flow depth upstream from the structure for any given constant value of discharge. The two flow depths, normally measured when submerged flow exists, consist of a depth upstream from the structure, which is used also for free flow conditions, and a depth of flow located any place downstream from the structure. The initial studies in which the submerged flow analysis was developed were made on flat-bottomed flumes (Hyatt, 1965; and Skogerboe, Walker, and Robinson, 1965). Later studies verified the …

Evaluation Of Free And Submerged Flow Data For Large Parshall Flumes, M. Leon Hyatt, Gaylord V. Skogerboe
Reports
Because the accurate measurement of water plays such an important part in water management, such structures as weirs, orifices, calibrated gates f and flumes have been developed. These structures provide the means for reasonable measurement of the smaller flows (1: .. 100 cfs), but for the large flows (100-3,000 cfs) the current meter, large Parshall flume, and various other flumes are commonly used. Where a permanent structure is required, the most widely accepted and utilized method for measurement of large flows is probably the Parshall flume. The purpose of this report has been to collect the existing flow data for …

Application Of Electronic Analog Computer To Solution Of Hydrologic And River Basin Planning Problems: Utah Simulation Model Ii, J. Paul Riley, Duane G. Chadwick, Jay M. Bagley
Reports
As demands upon available water supplies increase, there is an accompanying increase in the need to assess the downstream hydrologic system. At Utah State University this problem is being approached by electronic analog simulation of the hydrologic system. Modeling concepts are based upon the development of basic relationships which describe the various hydrologic processes. Within a system, these relationships are linked by the continuity -of-mass principle which requires a hydrologic balance at all points. Once established, the model is applied to any particular geographic unit by determining the appropriate constants of the hydrologic equations. The analog computer is ideally suited …

Mathematical Hydraulics Of Surface Irrigation, Cheng-Lung Chen
Reports
The general hydrodynamic equations for a spatially varied unsteady flow in a prismatic open channel having an arbitrary cross-sectional shape can be derived from the equations of continuity and momentum. The assumptions based on the general concept of hydrodynamics and the theory of shallow water is introduced. The mathematical models in the surface irrigation can be formulated by these equations of motion with the appropriate initial and boundary conditions prescribed at the singularity point (the origin in the x, t-plane) and at x = 0. Therefore, the flow in the surface irrigation must be described by solving the boundary-value problem …
