Evaluating Water Policy Options By Simulation, Ann W. Peralta, Richard C. Peralta, Keyvan Asghari

Civil and Environmental Engineering Faculty Publications

Computer simulation models are used to predict the effects of three sample water policy decisions on selected conjunctive water use/sustained groundwater yield strategies for the Arkansas Grand Prairie. The three applications illustrate the facility of the target objective approach in providing an interface for legal, economic and engineering analysis. The approach is used to evaluate potential water management decisions at the judicial, legislative and water management district levels

Conjunctive Use/Sustained Groundwater Yield Design, Richard C. Peralta

Civil and Environmental Engineering Faculty Publications

Assuring the sustained availability of groundwater from all parts of an aquifer system is analogous to assuring that the potentiometric surface does not change over the long term. Such a steady-state surface is maintained by a specific spatially distributed pattern of groundwater withdrawal. The finite difference form of the linearized Boussinesq equation for steady two-dimensional flow through porous media is used in models that design optimal regional potentiometric surfaces and the conjunctive water use/sustained yield strategies that maintain them. Presented objectives of such models include minimization of unmet water needs. minimization of the regional cost of attempting to satisfy water …

Spontaneous Coherent Pulsations In Ring-Laser Oscillators: Stability Criteria, Lee W. Casperson

Electrical and Computer Engineering Faculty Publications and Presentations

The stability criteria implied by a simplified semiclassical laser model are considered in detail. It is found that two types of criteria must be distinguished. The first concerns the smallest pump rate for which infinitesimal perturbations of the steady-state solution will increase with time, and the second concerns the smallest pump rate for which large amplitude modulations will not damp away.

Putting The Lid On Spares : A New Estimating Concept, George Zahodnick

Theses

Government standards and regulations, such as the CASB and FAR can be used as a guide by Contractors in preparation for negotiating orders for spare parts. More recently, in response to bad publicity involving spares, Contractors and Government officials have shown a trend toward greater micromanagement in the military acquisition process.

Spares proposal preparation, which was already often time consuming relative to dollars proposed for parts, has become an extremely serious subject often requiring additional levels of internal review and comprehensive supporting documentation. As a result, a considerable amount of new business expenditures can be associated with preparing proposals for …

Application Of Manufacturing Resources Planning To Repetitive Manufacturing Environments, Irma L. Yuen

Theses

Most of the methodology for Manufacturing Systems has been devoted to Job Shops. Frequently the assumption has been made that, because Job Shops are the most complicated their methodology should fit Repetitive Manufacturing as well.

For years the Repetitive producers had been ignored as Production and Inventory Control Techniques were developed, implemented and refined to assist discrete Job Shops environments with Material Planning problems.

The application of modern Production and Inventory Control Techniques especially MRP II in the Repetitive Manufacturing Industries is receiving increasing attention from experts in the Production and Inventory Control field.

During the research for this Thesis …

Human Factors In The Design Of Computer Graphics Input/Output Interfaces, Michael Uche Amadi

Theses

Computers are used for solving problems of various kinds and therefore, if the users are to fully benefit from the systems, they must be considered during the earliest stages of the system development. There are three major classes of computer users namely: naive, managerial, and scientific-technical. These users have different characteristics that the designer must consider within his/her system. Only by including such distinctions will these user groups each be able to perform at their respective optimum levels. Just as there are different users, there are also numerous applications to which computers can be applied. This thesis will be restricted …

An Examination Of The Power Spectral Density Function, James Edward Coleman

Theses

The power spectral density (PSD) function is a characterization of an (ideal) signal or set of signals. It is usually associated with a stationary random process, but it need not be. In fact, to study its properties it is desirable to divorce the power PSD from any extraneous structure that may conceal its properties. Specifically, it is desirable to study Sτ(f) = | Xτ(f)|²/2T and determine how it approximates the power spectrum of a power signal S (f) = τ[R(τ)].

It is shown that it cannot be concluded (contrary to what some of the literature has reported) that …

Measuring R And D Productivity, Richard A. Pappas, Donald S. Remer

All HMC Faculty Publications and Research

Measuring the productivity of an R&D organization is extremely tricky. Productivity is usually defined as a ratio of an output, like number of cars produced on an assembly line, to an input, like the wages paid the workers. While R&D may have a measurable input, the output is often intangible and difficult to quantify. This is further complicated because the return from an R&D department may not be realized for one or two decades,which means the time lag is much higher than in factory measurements. Furthermore, many researchers believe that this kind of measurement may be counterproductive,since the mere act …
