Radiative Lifetime Of The B ²Σˉ State Of Ch, Richard A. Anderson, Jerry Peacher, David M. Wilcox

Physics Faculty Research & Creative Works

The radiative lifetimes of the N'=3 to 15 rotational states of the v'=0 level of the B ²Σ^- state of CH were measured. Emission lines were observed to N'=15, but no lines above this rotational state were observed. This result agrees with previous studies. The lifetimes of all rotational states were between 300 and 400 ns. Previous measurements have indicated that the N'=15 level might have a lifetime as short as 100 ns.

Computer Manpower In The United States - Supply And Demand, John Wesley Hamblen

Computer Science Faculty Research & Creative Works

At a time when new departments of computer science, data processing, information science, information systems, etc. are being created and existing departments are trying to grow and compete with more established disciplines for scarce resources, it seems imperative that we attempt to keep abreast of the needs of industry and government for the graduates of these programs. This need must be monitored and matched against the production of graduates at all appropriate levels. The author has assembled extensive data on the latter over the past eight years while at the Southern Regional Education Board in Atlanta, GA (USA) during the …

Inelastic Reserve Capacity Of Cold-Formed Beams With Stiffened Compression Elements, Hans Peter Reck, George Winter, Teoman Peköz

CCFSS Library (1939 - present)

PREFACE The present Report No. 356 deals with the inelastic reserve strength of cold-formed beams with stiffened compression flanges. The usual elastic design criterion regards the initiation of yielding in the outer fibers as defining failure. This criterion is used in Part I of the A.I.S.C. Specification and in the A.I.S.I. Specification for the design of steel structures. On the other hand, for so-called compact sections, as defined in the A.I.S.C. Specification, it is known that the actual maximum moment of a cross-section exceeds the initial yield moment and is reached only when yielding spreads over the entire section (complete …

The Energy Conservation Implications Of Master Metering Of Electric Service In Apartments, Gordon Gross

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

A study has been made of the difference in electricity usage between residents of "Electricity included" apartments and those tenants who pay individual "light bills." The factors which influence owners' and builders' choices of metering service are discussed in detail.

Data taken from over 100 apartment buildings or complexes in 10 major U.S. metropolitan areas and from over 50 major electric power companies are used as the basis for the reported results. Contractors estimates of the costs to convert building service from master to individual meter and some bases for these costs are presented.

The energy conservation potential which might …

Choosing Alternative Energy Systems Under Conditions Of Uncertainty, Dennis Costello

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

A methodology for simulating the decision process of an investor deciding between alternative energy systems is presented. The approach assumes the investor bases his decision on cost (or rate of return) and risk. Risk is treated directly in the model and not reduced to a certainty equivalent. The rate of return-risk characteristics of many system combinations allows them to be eliminated as viable choices to the investor without reference to his personal attitude toward risk.

Planned Reduction In Electrical Energy Use In Nashville - Davidson County, Tennessee: A Preliminary Assessment, Barry D. Lichter, William F. Flanagan, Robert S. Goodrich, James K. Sebenius, C. Paul Beach

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

An assessment was carried out of the impacts of the various alternative strategies designed to reduce the rate of electrical energy use in the Nashville-Davidson County area, in the light of a potential crisis in supply. Seven strategies were identified among the major categories of voluntary reduction, price regulation, and mandatory reduction. Thirty-three sub-sectors were identified among residential, commercial and industrial users, and the consequences of imposing the strategies were assessed using a cross-impact matrix. The value of the methodology as an aid to public policy formulation lies in its possible extension to allow direct participation of various affected publics.

Coal Conversion Technology, Karen A. Dollar, Henry Allen Wiebe

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

Energy consumption is rapidly increasing throughout the world and the United States is no exception. Efforts to reduce the dependence on oil imports have focused on utilization of our coal resources. This paper examines various coal conversion processes and presents a method for evaluating their contribution to energy production.

Self-Consistency In Estimating Future Electrical Energy Consumption, W. D. Devine Jr., C. C. Calligan, O. D. Osborne

UMR-MEC Conference on Energy / UMR-DNR Conference on Energy

A socio economic computer simulation model for the State of Oregon is described. The Oregon State Simulation Model (OSSIM) includes a thirty-seven sector model of electrical energy consumption. Coupling between this model and the OSSIM ensures self-consistent scenarios of socio economic phenomena which underlie energy consumption. One of the purposes of this effort is to help state-level decision makers understand the determinants of electricity consumption within a context of changing economic conditions.

Flow Visualization Studies Of Check Valve Vibrations, D. S. Weaver, F. A. Adubi

Symposia on Turbulence in Liquids

A swing-type hydraulic check valve was found to vibrate continuously when a damper was applied to prevent slamming. A research program was conducted to develop an understanding of the phenomenon and thereby determine a method of alleviation. This paper describes the flow phenomena observed during flow visualization studies of a two dimensional full scale model of the valve. Such observations give insight into the mechanism of vibration.

Separation Of Low Reynolds Number Flows Around A Corner, T. Matsui, M. Hiramatsu, M. Hanaki

Symposia on Turbulence in Liquids

It was shown experimentally that low Reynolds number flows around a sharp corner do not separate at the corner, and separation points move downstream from the corner with decrease in Reynolds number. For the flow in a channel with a backward-facing step, the experimental results showed a good agreement with those of numerical calculation for the position of separation points and the length of standing vortices.

Turbulent Pressure Spectrum Measurements On A Compliant Surface, R. N. Brown

Symposia on Turbulence in Liquids

Experimental results obtained by measuring the drag, wall pressure fluctuations, and radiated sound from a compliantly coated cylinder, 21 inches in diameter, and rotating in water are described. The compliant layer was a 1/4-inch thick closed cell, air-filled neoprene which was mounted on the 3/8-inch thick aluminum cylinder walls. Results are presented for four speed conditions; one condition is below the speed where a sudden increase in drag is obtained, and the other speed conditions are at and above this critical speed. In general, the results indicate a surface which becomes increasingly more roughened as the critical speed is exceeded.

Characteristics Of Laser Anemometer Signals And Frequency Demodulators For Highly Seeded Flows, R. V. Edwards

Symposia on Turbulence in Liquids

An analysis of the general characteristics of laser anemometer signals for liquid flows is made. Three detection schemes are analyzed:
(1) Spectral analysis of the photodetector output,
(2) frequency trackers, and
(3) counters
Where known, the strengths and weakness of each method are analyzed.

Periodic And Random Excitation Of Streamlined Structures By Trailing Edge Flows, W. K. Blake

Symposia on Turbulence in Liquids

This paper is an examination of semi-empirical techniques which are shown to be effective in predicting the response of hydrofoils to flow excitation. Examples are given for buffeting by inflow turbulence, excitation by the boundary-layer pressures on the hydrofoil, and linear and non-linear excitation by vortex street formation in the wake. Co-ordinated aerodynamic and hydrodynamic measurements are used in Reynolds number - scaled experiments to determine both the flow induced forces and the hydro-elastic behavior on cantilever struts. An analytical formulation based on normal mode theory is used to combine the results.

An Investigation Of The Criteria Controlling Sustained Self-Excited Oscillations Of Cylinders In Flowing Water, R. King

Symposia on Turbulence in Liquids

In this paper, water channel experimental data are discussed and compared with conventional wind-tunnel data. Stability criteria are proposed for the cross-flow and flow directions of oscillation. Fluctuating drag force coefficients are deduced from a linear mathematical representation of the cylinder located in flowing water and oscillating in the flow direction.

Intrinsic Viscosity Of Stiff Dumbbells From Time Correlation Functions, Gerald Wilemski

Physics Faculty Research & Creative Works

The intrinsic viscosity of a suspension of stiff dumbbells is evaluated by a time correlation function method. The required moments of the internal coordinates are calculated directly from the diffusion equation, without explicit evaluation of the Green's function. For the rigid dumbbell, the correct high frequency limit is obtained, disposing of recent doubts over this possibility. The interplay of dumbbell stiffness and shearing frequency is also illustrated.

Energy And Angular Distribution Of Electrons Ejected From Helium By Fast Protons And Electrons: Theory And Experiment, Steven Trent Manson, Larry H. Toburen, Don H. Madison, Nikolaus Stolterfoht

Physics Faculty Research & Creative Works

A comprehensive study of the angular and energy distributions of electrons ejected in collisions of fast electrons and protons with He is presented. New experimental results for 300-keV, 1-MeV, and 5-MeV proton impact are reported along with theoretical results for 2-keV electron impact and 100-keV, 300-keV, 1-MeV, and 5-MeV proton impact. The theoretical results, based upon Born approximation with Hartree-Slater initial discrete and final continuum wave functions, show excellent agreement with experimental electron-impact results. Serious discrepancies are found between theory and experiment in the angular distribution of ejected electrons for forward angles for 100- and 300-keV proton impact; the discrepancies …
