Self-Consistent Dielectric Response Of A Quasi-One-Dimensional Metal At High Frequencies, P. F. Williams, Aaron N. Bloch

P. F. (Paul Frazer) Williams Publications

We present the results of a calculation of the frequency- and wave-vector-dependent longitudinal dielectric function of a quasi-one-dimensional electron gas. The electrons are taken to be localized to the chains and both the tight-binding and free-electron extremes are considered along the chain axis. Local-field effects are included. Dispersion curves for plasmons and single-particle-excitation spectra are presented. We find that the plasmon modes are not Landau damped and that for long wavelengths these modes have eigenfrequencies ranging continuously from the usual three-dimensional plasma frequency for propagation along the chain axis to zero for propagation perpendicular to it. Finally, we discuss the …

Optimal Highway Safety Improvement Investments By Dynamic Programming [Aug. 1974], Jerry G. Pigman, Kenneth R. Agent, Jesse G. Mayes, Charles V. Zegeer

Kentucky Transportation Center Research Report

The process of determining which projects to implement under a given budget, and which to defer until later, is central to the planning and management of highway systems. With a limited budget for construction, maintenance, and safety improvements, investments which will produce the optimal benefits must be chosen. This is often impossible to accomplish without the aid of a computer because of the complexity of the problem. Dynamic programming has been tested and verified as an efficient method for selecting priority projects to derive maximum benefits.

There are several approaches to priority programming as it is related to the capital …

Optical Excitation Of Plasmons In A Quasi-One-Dimensional Conductor, P. F. Williams, M. A. Butler, D. L. Rousseau

P. F. (Paul Frazer) Williams Publications

We have carefully determined the optical spectrum of K₂Pt(CN) ₄Br_0.3 - 3H₂O near the reflectivity edge. Our data reveal, in addition to the expected monotonic background, a broad peak in ε₂ (ω) above a threshold coinciding with the zero of ε₁ (ω) near 16000 cm^-1. We assign this band to indirect excitation of plasmons. Details of the excitation of plasmons are discussed with particular attention being paid to the problems presented by the one-dimensional character of the material. It is concluded that the electronic structure of this material cannot be …

"Before" Evaluation Of Economic Growth Center Developmental Highway (Ky 55, Campbellsville-Lebanon), Joseph T. Farmer, Jerry G. Pigman

Kentucky Transportation Center Research Report

Before-and-after impact studies were selected as the means of determining the effect of reconstructing a 4.813-mile (7.744-kilometer) section of KY 55 between Campbellsville and Lebanon. The area, though still depressed in terms of per capita income and employment, has many resources available for growth. The study area is predominantly an agriculturally-oriented economy. However, manufacturing employment has increased in recent years, mainly because of industrial sites made available by local industrial commissions.

Overall, social services appear to be adequate and very near statewide averages. Recreational facilities are not highly developed and are primarily of the summer outdoor type.

Temperature Distributions In Asphaltic Concrete Pavements, Herbert F. Southgate

Kentucky Transportation Center Research Report

The straight-line relationship between temperatures at a given depth and the surface temperatures combined with 5-day average air temperatures appears to be as valid for upper New York State and Arizona as it was for Maryland. The main differences were in the ranges and mean temperatures. Values given herein are for straight-line equations for all 24 hours and for the depths of 2, 4, 6, 8, 10, and 12 inches (5.1, 10.2, 15.2, 20.3, 25.4, and 30.5 cm). The original concept appears to be valid and may be used with confidence for estimating pavement temperatures at other latitudes and longitudes.

A Biquadratic Realization Using A Distributed-Lumped-Active Rc Network., James Lee Jorgensen

Electrical and Computer Engineering ETDs

A common method used to realize high-order active filters is to cascade second-order (biquadratic) and first-order filter sections, to achieve the desired voltage transfer function. First-order sections are easily realized by simple passive sections; the basic building block in this method is, therefore, a network that realizes a general biquadratic voltage transfer function (BVTF).

Water Salvage Potentials In Utah, Volume I. Open Water Evaporation And Monolayer Suppression Potential, Trevor C. Hughes, E. Arlo Richardson, James A. Franckiewicz

Reports

An estimate of the potential in Utah for evaporation suppression by the monolayer film method is presented. The model estimates evaporation suppression as a function of wind speed, a four parameter exposure factor, and reservoir size. The estimated suppression factors vary from 0 to 30 percent and average 11 percent of the statewide total annual evaporation. Estimates of May to October evaporation and suppression potential are calculated for each of the 227 impoundments in the surface water inventory. A forthcoming report in this series will examine the potential for evaporation suppression by thermal destratification. This procedure, which is already being …

The Effect Of Unreinforced Cutouts On The Buckling Of Thin Conical Shells Loaded By Central Axial Compression, Garla Arjuna

Mechanical & Aerospace Engineering Theses & Dissertations

Analytical trends for the linear bifurcation buckling of thin isotropic right-circular-conical shells with unreinforced cutouts are investigated. Clamped, constant-thickness conical shells with homogeneous, isotropical material properties are analyzed for uniform axial compression. The buck­ ling loads are obtained by the use of the STAGS (Structural Analysis of General Shells) computer program which is based on a finite difference numerical approach. Variables defining the geometry of the cutout and the cone are nondimensionalized and the relationship between the nondimensional buckling load and nondimensional cutout parameter is established. A range of the cutout sizes is investigated for which linear bifurcation buckling results …

Application Of Boundary Layer Theory To Suction Through Streamwise Slots In Wind Tunnel Walls, Michael Harold Berger

Mechanical & Aerospace Engineering Theses & Dissertations

A theoretical investigation at Mach 6 and 8 has been conducted on a model of a wind tunnel sound shield. The flat plate model consists of interchangeable circular and wedge shaped longitudinal rods with gaps between the rods for boundary layer removal. One­ dimensional gas dynamics results have been applied to model the pressure distribution for the array of cylinders. Comparisons with experimental pressure distributions and numerical potential flow solutions indicate good agreement. It has been demonstrated that stagnation line heat transfer can be accurately predicted for laminar and-turbulent flow for circular cylinders. The flow around the wedge rods was …

Design Of I-Shaped Beams And Columns With Diaphragm Bracing, S. J. Errera, T. V. S. R. Apparao

CCFSS Library (1939 - present)

Cold-formed steel panels often are used as wall sheathing, roof decking or floor decking in steel framed buildings or pre-engineered metal buildings. Diaphragms formed by interconnecting these panels have considerable in-plane shear resistance, and can be utilized as bracing against buckling for individual members of a steel frame. For wall columns the diaphragm may be either directly attached or connected to girts which in turn are connected to the columns. A procedure is presented for the design of I-section beams and columns with diaphragm or diaphragm-girt bracing. The procedure is based on the ultimate load capacity of fully braced members, …

The Theory Of Multiple Measurements Techniques In Distributed Parameter Systems, Babajimi Claudius Okunseinde

Dissertations

A comprehensive theory of multiple measurements for the optimum on-line state estimation and parameter identification in a class of noisy, dynamic distributed systems, is developed in this study. Often in practical monitoring and control problems, accurate measurements of a critical variable are not available in a desired form or at a desired sampling rate. Rather, noisy independent measurements of related forms of the variable may be available at different sampling rates. Multiple measurements theory thus involves the optimum weighting and combination of different types of available measurements. One of the contributions of this work is the development of a unique …

A Study Of An Adiabatic Tubular Reactor For The Multiple Chlorination Of Methane, Richard L. Braun

Theses

A computer program has been developed which simulates the multiple chlorination of methane in an adiabatic, tubular reactor. Euler's method is used to approximate the solutions of the programs differential equations.

The program is designed to determine the amount of an inert diluent required in the feed stream to attain some specified conversion of methane in a safe and efficient temperature range. Particular emphasis is put on determining the amount of diluent required to attain 98% conversion of methane at an outlet temperature of 723°K. The program also determines the reactor volume necessary to achieve the specified conversion, and the …

The Steady State Heat And Temperature Distribution Of A Hot Sphere Within An Infinite Wedge, David W. Horwat

Theses

This thesis presents a mathematical model of the steady state heat and temperature distributions of a hot sphere located along the midplane of an infinitely long wedge of any arbitrary central angle. The heat and temperature distributions of this geometric configuration are of immense value, since through the use of this model as a wedge shaped unit cell the description of any number of hot spheres, arranged in a regular planar array can be immediately determined.

The method of reflections is used to solve Laplace's equation , V²T=O , analytically using the sphere and the wedge walls as …

The model system sodium nitrate ? water on an ion retardation resin adsorbate was employed. Equations defining maximum values of certain important parameters such as the bottom product flow rate and reservoir displacement rate were developed by extending previous theories of parametric pumping. Experimental runs were carried out using parameters whose values were both less than and greater than the maximum values predicted for optimal …

The Determination Of An Optimum Plant Capacity In A Dynamic Economy, Frederick Louis Monesmith

Theses

A. Monte Carlo computer program has been developed in which the optimum plant capacity is determined by comparing calculated profitability criterions for various plant capacities. The estimates for input variables are developed into probability distributions. This data is then used to calculate a probability distribution for a-profitability criterion. In this thesis approximately thirty input variables are developed into beta distributions. Each variable must be estimated with a ninety percent probability estimate, a most likely probability estimate and a ten percent probability estimate. The three level estimates for each variable completely describe the beta distribution. Approximately half of the beta distributions …
