Art Theory & Design Process, Bryce W. Bushman

Undergraduate Honors Capstone Projects

Art is not an object; it is a process that has three components; the individual, the experience, and the expression. The individual is the person creating art and includes all of their unique complexities, recognizing that people are dynamic. The experience includes everything that goes on within and around the individual that results in, and links them to, the expression. The expression is the result of the individual's experience, a manifestation or product, which may be tactile and physical or abstract and psychological, usually both. Only one of the three components need be unique for art to occur. Design process …

Develop Design Data On Pressure Loss Of Large Pipe Fittings, Patrick Dent

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pressure loss coefficients were determined for large radius ells, large concentric pipe reducers, and expansions, as well as large pipe tees. The fittings tested were 12, 16, 20, and 24 inch forged steel weld. Forty individual fittings from four different manufacturers were tested to determine loss coefficient values. Each test fitting was examined at a specified range of pipe velocities to determine mean and variation of loss coefficients. Tees were also examined for mean and variation of loss coefficients over a range of flow distributions.

Currently no data exists for pipe fittings of these larger diameters. This study will provide …

On The Design Of International Environmental Agreements For Identical And Heterogeneous Developing Countries, Amitrajeet A. Batabyal

Economic Research Institute Study Papers

In the 1992 Rio Earth Summit, developing countries (DCs) were adamant that in order to protect the environment for the future, new institutions were needed which would channel resources from the wealthy developed countries to the poor DCs. With this backdrop, I analyze the problem faced by an imperfectly informed supranational governmental authority (SNGA) who wishes to design an International Environmental Agreement (lEA). The SNGA cannot contract directly with polluting firms in the various DCs, and he must deal with such firms through their governments. Further, the SNGA is constrained by limited financial resources available for environmental protection. I study …

The Design Perspective In Resource And Environmental Economics, Amitrajeet A. Batabyal

Economic Research Institute Study Papers

Despite the fact that most regulatory problems in resource and environmental economics are design problems, rarely have resource economists explicitly adopted the design perspective in modeling such problems. In this note I argue that the design perspective should be adopted. I highlight the merits of the design approach by studying an old problem-the regulation of an open access fishery (OAF)-in a new way. I show that the design perspective has important implications for fisheries management.

An Agenda For The Design And Study Of International Environmental Agreements, Amitrajeet A. Batabyal

Economic Research Institute Study Papers

The combination of a general greening of international political debate, and the events of 1992 at the Rio Earth summit have led to great interest in the question of global environmental protection. While it is recognized that international environmental agreements (IEAs) are the means by which the earth's fragile environment is most likely to be protected, this recognition has been recent. Hence, there is very little formal research on the design and study of lEAs. As such, in this paper, I propose and describe a research agenda for the design and study of lEAs. Very generally, I propose that we …

Design And Construction Of An Active Alignment Demonstrator For A Free-Space Optical Interconnect, G. C. Boisset, B. Robertson, Harvard Scott Hinton

Electrical and Computer Engineering Faculty Publications

An x-y active alignment system based on Risley beam steerers is described. The demonstrator features a quadrant detector which detects the misalignment error between the center of a spot of light and the center of the quadrant detector. This misalignment error is then used by a new algorithm to calculate the rotational displacement required for the two Risley beam steerers to steer the spot of light to the center of the quadrant detector. The experimental results indicate that any spot misaligned by up to 160 μm on the quadrant detector will be systematically centered by the demonstrator system.

The Design Of An Augmentative Communications Device, Darren Blaser, Scott Sorenson

Undergraduate Honors Capstone Projects

There is an extremely large number of people in the modem world who have difficulty communicating. Among these are approximately 25 million people with cerebral palsy. Cerebral palsy is a disability that is usually caused during, or shortly after birth. Cerebral palsy usually affects a person's motor skills and sense of balance, often rendering them incapable of speaking clearly enough to be understood well. Because this group of people cannot communicate as effectively as other individuals, many uninformed people suppose they do not have as great a need to speak, to say things like, "How are you?", ''I'm Hungry", "Thank …

The crest of the model spillway was constructed in the shape of a …

The Use Of Object-Oriented Design Methodologies In Systems Design, Rick C. Larkin

Undergraduate Honors Capstone Projects

Object-oriented design methodologies, along with object-oriented programming techniques, have recently gained significant popularity as their advantages have become evident. Traditional methodologies following the structured approach have not been successful in providing an accurate model of the business system.Object-oriented techniques, where an object in the computer system corresponds to a real-world object, have been much more successful in accurately modeling the business system and its environment.

Object-oriented methodologies provide many advantages over structured approaches to systems design. Concepts such as data hiding, encapsulation, inheritance, dynamic binding, and polymorphism help to achieve an accurate and flexible system that is resistant to corruption …

Ultrahigh Vacuum Chamber For Synchrotron X-Ray Diffraction From Films Adsorbed On Single-Crystal Surfaces, John R. Dennison, S. K. Wang, P. Dai, T. Angot, H. Taub, S. N. Ehrlich

All Physics Faculty Publications

An ultrahigh vacuum chamber has been developed for structural analysis of adsorbed films and single‐crystal surfaces using synchrotron x‐ray diffraction. It is particularly well suited for investigations of physisorbed and other weakly bound films. The chamber is small enough to transport and mount directly on a standard four‐axis diffractometer and can also be used independently of the x‐ray diffractometer. A low‐current, pulse‐counting, low‐energy electron diffraction/Auger spectroscopy system with a position‐sensitive detector enables in situ characterization of the film and substrate while the sample is located at the x‐ray scattering position. A closed‐cycle He refrigerator and electron bombardment heater provide controlled …

Effects Of Seeder Design And Seed Placement On Seedling Size And Cull Rates At Western Forest Nurseries, United States Department Of Agriculture, Forest Service

Forestry

Nursery plots sown with the Summit Precision Seeder and the Oyjord Seeder were compared with plots oversown and hand thinned to desired spacings. We studied 26 seedlots of nine conifer species at five Forest Service, U.S. Department of Agriculture, nurseries. Results varied with nursery, species, and seed characteristics. Thinned plots produced less clumping and fewer gaps between seedlings, but showed little or no difference in seedling size, nor in the number of acceptable seedlings.

Mix Design Investigation - Roller Compacted Concrete Construction, Upper Stillwater Dam, Utah, United States Department Of The Interior, Bureau Of Reclamation

Dams

Upper Stillwater Dam will be the first concrete dam constructed by the Bureau of Reclamation utilizing the RCC (roller compacted concrete) construction technique. RCC is concrete with zero slump consistency, which is deposited in horizontal lifts and consolidated in place by a smooth drum vibrating roller. This method of construction was first proposed in the early 1970's [1, 2, 3]* and was demonstrated successfully in emergency spillway repairs at Tarbela Dam, Pakistan [3], in the construction of Shimajigawa Dam, Japan, and Willow Creek Dam, Oregon.

Water For The 21st Century, Will It Be There?, Richard C. Peralta, Ann W. Peralta, Leslie E. Mack

Civil and Environmental Engineering Faculty Publications

One of Arkansas' major water management goals is to provide adequate water for agriculture, the economic mainstay of the state. Effective water management requires inputs from engineering, economics, law, administration, and environmental concern, all in a matrix of public education, participation and communications. Groundwater levels in eastern Arkansas have been dropping for decades as irrigation for rice, other row crops, and fish farming have increased substantially. Additional surface water supplies are available from the adjacent rivers but there are competition, conflict of use, and jurisdictional problems involved. A critical path sequence chart was designed to include all the research steps …

Design And Operating Criteria For Rural Water Systems, James E. Garton, Gary L. Goodwin, Richard C. Peralta

Civil and Environmental Engineering Faculty Publications

Rural homesites in the United States require the availability of high quality water. One means of meeting this need is with the rural water district, a system composed of tank storage and a pipe network serving a number of homes. The tanks are filled by pumping during periods of minimal water use and serve as the immediate water source for homes.

Optimum design requires consideration of not only immediate needs and economic factors but also the possibility of expansion at some future date. Accurate prediction of monthly usage rates is sometimes necessary to set contractural needs. Daily water use per …

Design Criteria For Usu Stilling Basin Pipe Flow To Open Channels, Chi-Yuan Wei

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Criterion have been developed in this study for designing a stilling basin to serve as a transition from pipe flow to open channel flow. The purpose of the structure is to prevent erosion in an open channel. The unsteadiness, or smoothness, of the water surface in the model basin was used as the criterion for evaluating the effectiveness of the structure for energy dissipation.

The introduction of a short-pipe energy dissipater in the stilling basin has proven effective in dissipating energy. The stilling basin was designed for a fully submerged pipe outlet. The inflow pipe and the dissipator pipe were …

Design Optimization Using Model Estimation Programming, Richard Kay Brimhall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Model estimation programming provides a method for obtaining extreme solutions subject to constraints. Functions which are continuous with continuous first and second derivatives in the neighborhood of the solution are approximated using quadratic polynomials (termed estimating functions) derived from computed or experimental data points. Using the estimating functions, an approximation problem is solved by a numerical adaptation of the method of Lagrange. The method is not limited by the concavity of the objective function.

Beginning with an initial array of data observations, an initial approximate solution is obtained. Using this approximate solution as a new datum point, the coefficients for …
