Increasingly more commercial products for controlling erosion are being produced nationally and there remains a need to evaluate the effectiveness of these, one against another, in order that potential users may make cost-effective decisions in their use. CONWED recognizes this need and has funded the comparative testing of its own products and some of those of leading competitors throughout the country. The …

The Water Requirements And Pollutant Potential In The Gasification Of Carbonaceous Shales, Jeffery A. Cissell, V. Dean Adams, Joel E. Fletcher, Daniel S. Filip, Dennis B. George

Reports

A laboratory-scale, batch operated gasifier was used to evaluate the heating value, process and cooling water requirements, and water pollution potential of gasification of carbonaceous shales. These potentially valuable fossil fuels are found over large areas of Southern and Eastern Utah and vary widely in quality depending on the amount of intermixed inorganic material. The results indicate that a synthesis gas, consisting primarily of hydrogen and carbon monoxide, can be produced from carbonaceous shales. The total heating values of the synthesis gas from the carbon shales examined ranged from 4 to 62 percent of that of coal. The process water …

A stand-by wintertime cloud seeding program was designed for all sections of the state. An economics model was then used to determine benfits to the state as a result of the seeding program.

Sprinkler Application Of So2 - Treated Groundwater At The Sandarosa Farm, Snowville, Utah, V. Dean Adams, Craig S. Criddle

Reports

Sulfur is recognized as one of the essential elements for plant growth. It has also been used in agriculture for reclamation of saline and sodic soils. During the reclamation process there is the potential benefit of increased availability of phosphorus and certain micro-nutrients for plant uptake. There is also potential for increased infiltration thus increasing water utilization efficiency.

Sulfur has been applied to soils in a flake or nodule form, by the addition of sulfuric acid and most recently by the application of sulfurous acid. The raw sulfur addition technique is accomplished by spreading raw sulfur on the soil and …

Octal-Tree Spatial Sorting And Its Applications, Jeffrey L. Posdamer

All Computer Science and Engineering Research

An octal tree subdivision recursively divides a bounded three-dimensional volume into octanta about an internal division point. This scheme has been used to represent cellular or enumerated voxel models of solid objects. Given one or more sets of points sampled from the surface of a solid, an octal tree may be generated in which each leaf node contains m or less points. By specifying the tree traversal rule, the points are accessed in a sorted order. By defining m=3, a divide-and-conquer surface triangulation algorithm may be developed which does not require special sampling conditions (such as co-planarity) on subsets of …

Robotics And The Conservation Of Human Resources, Robert U. Ayres, Steven M. Miller

Research Collection School Of Computing and Information Systems

Due to rapid expansion in the field of robotics, policy issues have arisen in regard to developing human skills to deal with the new technology and to deal with the obsolescent human skills which are the inevitable result of this growth pattern. Industrialists, educators, union leaders, and government officials must work cooperatively to insure that the coming changes are made with minimum disruption. Improved training methods and courses have to be developed for the skills needed to control, manage and supervise the new machines. Some of the ways in which this can be accomplished are through offering financial incentives for …

On The Uniqueness Of Solution Of Magnetostatic Vector‐Potential Problems By Three‐Dimensional Finite‐Element Methods, O. A. Mohammed, W. A. Davis, B. D. Popovic, T. W. Nehl, Nabeel Demerdash

Electrical and Computer Engineering Faculty Research and Publications

In this paper, particular attention is paid to the impact of finite‐element approximation on uniqueness and to approximations implicit in finite element formulations from the uniqueness requirements standpoint. It is also shown that the flux density is unique without qualifications. The theoretical and numerical uniqueness of the magnetic vector potential in three‐dimensional problems is also given. This analysis is restricted to linear, isotropic media with Dirichlet Boundary conditions. As an interesting consequence of this analysis it is shown that, under usual conditions adopted in obtaining three‐dimensional finite‐element solutions, it is not necessary to specify div Ā in order that Ā …

Glass Surfaces Then And Now, Norbert J. Kreidl

Materials Science and Engineering Faculty Research & Creative Works

A reservoir of efficient instrumentation capable of detailed and quantitative exploration of glass surface features is now available in the face of the recognition of their crucial importance for both surface and bulk properties as well as performance. Yet it may be instructive to glance at what had been learned about glass surfaces by investigators before the advent of these intricate tools. Among such earlier findings are the recognition of the altered composition and structure of the surface layer, the extension of this disturbance to considerable depth, the effect of surface structure on adsorption, adhesion, wetting, finishing, etc. and on …

An Analytical Method For Quantifying The Electrical Space Heating Component Of A Cold Load Pick Up, Walter W. Lang, Max Darwin Anderson, David R. Fannin

Electrical and Computer Engineering Faculty Research & Creative Works

After an extended cold weather outage on a distribution circuit supplying a high saturation of electrical space heating, large transient overcurrent's persist for several hours because of the undiversified heating load. In this paper, the electrical space heating component of enduring demand is characterized by a smooth curve. Expressions are derived for the parameters of the curve in terms of the outage conditions and a statistical description of the residences. A method is suggested for using this characterization to determine the effects of a cold load pick up on the distribution circuit components. Copyright © 1982 by The Institute of …

Measurement Of Neck Development In Tensile Testing Using Projection Moire, Raghavan Srinivasan, C. S. Hartley, C. Raju, J. Clave

Mechanical and Materials Engineering Faculty Publications

The projection moire technique affords an accurate method of measuring the geometry of the necked region in a tensile specimen. Corrections to the measured stress, necessary to account for the triaxiality introduced by the neck, require values for the radius of curvature of the specimen at the minimum section. The spacing of fringes resulting from the interference between a grating projected on the specimen surface and a master grating not only provide information which permits calculation of the radius but also demonstrates any changes in symmetry resulting from plastic deformation. Results obtained by testing specimens of copper and mild steel …
