Protection Of Our Fragile Upper Atmosphere, Clayton Clark

Faculty Honor Lectures

Termination of U.S. government support for the Supersonic Transport, SST, may eventually cost the United States its leadership in aviation and billions of dollars in international trade losses, yet if the world wide SST program is allowed to continue, the costs to mankind as a result of damage to environmental resources could be much higher. The decision to terminate the project was heavily based upon concern for possible changes in the properties of the upper atmosphere as a result of SST operations in that realm, with consequent danger to plant and animal life on the Earth below. Briefly, the concern …

Ionization‐Enhanced Diffusion: Ion Implantation In Semiconductors, J Bourgoin, David Peak, J W. Corbett

All Physics Faculty Publications

A model for the diffusion of implanted interstitials during implantation is introduced and shown to be able to account for the tails observed in ion profiles. It is argued that mechanisms of ionization‐enhanced diffusion can explain some of the anomalous diffusion mechanisms observed in semiconductors. Indications for the existence of such mechanisms in the field of ion implantation in semiconductors are discussed.

Rocket-Borne Radiometric Measurements Of Oh In The Auroral Zone, J. W. Rogers, R. E. Murphy, A. T. Stair Jr., J. C. Ulwick

Space Dynamics Laboratory Publications

An Astrobee D rocket carrying a dual-channel radiometer (1.40- to .1.65-gm and 1.85- to 2.12-gm spectral band passes) was launched on March 6, 1972, at 0200 LT from Poker Flat, Alaska.T he spectrabl and passews ere chosens o that the lower (v -- 2, 3, 4, 5) and upper (v -- 7, 8, 9) vibrational levels of OH in the .Av -- 2 sequence could be monitored simultaneously. Launch criteria were established from groundsbased radiometric observations that indicated a steady.night airglow of 240 kR• in the 1.40- to 1.65-gm band pass 2 hours prior to and throughou•tt he flight.

Wood Production And Kraft Pulping Of Short-Rotation Hardwoods In The Pacific Northwest, Fred L. Schmidt, Dean S. Debell

Aspen Bibliography

For decades foresters and fiber-using industries throughout the world have been concerned with the problem of future procurement of wood fiber. Research has progressed on several promising approaches to this problem, including fertilization, genetic improvement, better control of competition, and more complete utilization. Recently another alternative has been suggested --- the production of hardwood fiber on very short rotations with coppice regrowth. The concept was first proposed by McAlpine et al. (1966) under the name, "silage sycamore". Since that time, tests of "silage" forestry have been initiated with other hardwood species in many regions of the United State and Canada …

Aspen Bibliography

A study was made to investigate the potential of several local puckerbrush or weed trees and shrubs as sources of fiber for papermaking. It is an extension of previous studies which were reported in Technical Bulletin 49 of the Life Sciences and Agriculture Experiment Station, University of Maine at Orono.

Computer Programs Supporting The Teaching Of Statistics, Chien-Hwa Liu

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

During the past few years there has been an increasing interest in developing computer packages to enhance the teaching of elementary statistics. The conventional ways of teaching statistics have used such devices as desk calculators, tables of functions, short-cut calculating formulas and electronic calculators, etc. to manipulate the involved computations. Electronic computers, in the past decade, have been broadly used in universities and colleges in many ways. It is only natural to extend the use of computers to the teaching function. Remote terminals can now be installed in any classroom and bring the computer to the students.

The Evaluation Of Glasser's Maximum Likelihood Method On Missing Data In Regression, Gayle M. Yamasaki

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Missing data in regression is often a problem to research workers because standard regression methods are applicable only to complete data sets. At present there are three general methods for solving the problem of missing data.

At first, the reduced data method, reduces the incomplete data set to a complete data set before analyzing. Although this method is very simple to apply, substantial amounts of information are sometimes lost when data is eliminated. This results in less precise estimates of the regression parameters.

The second method, generalized least squares, estimates the missing values through least squares techniques, thus obtaining a …

A Water Resource Management Model, Upper Jordan River Drainage, Utah, Bi-Huei Wang, James I. Felix, Rick L. Gold, Craig T. Jones, J. Paul Riley

Reports

As demands upon available water supplies increase within a river basin, there is an accompanying increase in the need to assess the downstream consequences resulting from changes at specific locations within the hydrologic system. This problem is approached in this study by digital computer simulation of the hydrologic system. Modeling concepts are based upon basic relationships which describe the various hydrologic processes. Within a hydrologic system these relationships are linked by the continuity-of-mass principle which requires a mass balance at all points. Spatial resolution is achieved by considering the modeled area as a series of subbasins. The time increment adopted …

Modification Of A Continuous Ice Crystal Replicator, Paul D. Thornley

Reports

A continuous ice-crystal replicator was modified by the addition of a gear drive to the cating wheel. This modification utilizes a positive drive force on the coating wheel rather than the friction force between the coating wheel and the film. The coating wheel operates successfully for at least 12 hours without slippage or damage to the film. Studies have uncovered several deficiencies in the replicator design which could be corrected. The correction of these deficiencies would lead to an improved quality of ice-crystal replicas. The need for continued studies in the fluid properties of Formvar solution is pointed out. Information …

A Streamflow Simulation Model For A Semi-Arid Region, Adnan A. Saad, L. Douglas James

Reports

A streamflow simulation model which would reproduce the essential feature of the hydrologic regime of a semi-arid region, in this case Jordan, was developmed and described. The model is intended to fit conditions which exist in such a region. The hydrologic processes components which represent the evaporation and the base flow distinguish the Jordan model from others. Development of each function of the model and its constants was based on all the minimal amount of data available. one year of data was used to calibrate the model for Wadi Zerqa watershed. The model was then applied to simualte four years …

Hydraulic Tests On Model Of Manifold Of The Pumps Of The 1974 Extension Of The Yorktown Power Station With All Combinations Of One And Two Branches Taken Out Of Operation, Roland W. Jeppson, Calvin G. Clyde, Charles Kincaid

Reports

Introduction: A description of the fabrication of the manifold model and the design of the facilities constructed to test the model under various steady state flow conditions is given in the previous report. All tests included in the last report were with equal flows occurring in each of the five branches. Since the operation of the prototype manifold will necessitate that one, and possibly two pumps, be taken out of operations when the demand for cooling water is at a minimum, Browth & Root, Inc. requested taht the performance of the manifold model be determined under steady-state conditions with: (1) …

Head Losses Due To Ring-Tite Filament Wound Elbows And Tees And Frictional Losses In Pipes Of Polyvinylchloride, Roland W. Jeppson

Reports

This study consists of collecting and analyzing experimental data to determine the Darcy-Weisbach friction factor for 6-inch and 4-inch PERMASTRAN® pipes and the head losses due to RING-TITE filament-wound 6-inch 90° elbows, a 6 x 6-inch tee under several modes of operation, and a 6 x 6 x 4-inch tee with the flow entering a 6-inch branch and leaving through the 4-inch branch. The test program consisted of 8 series of individual tests with each series giving data for flow rates for each series ranging from 150 gpm to either 1200 gpm or 1500 gpm depending upon the series. The …
