Effects Of The Energy Crisis On Traffic In Kentucky, Kenneth R. Agent, Donald R. Herd, Rolands L. Rizenbergs

Kentucky Transportation Center Research Report

The Arab oil embargo in mid-October 1973 curtailed availability of gasoline. Fuel conservation measures resulted in reduced travel and decreased traffic speeds. On March 1, 1974, posted speed was set at 55 mph on rural highways in Kentucky. Traffic volumes, speeds, and accidents for the rural highway during the period known as the "energy crisis" and its after effects were compared to the corresponding period a year earlier.

Traffic volumes began to decline in December 1973 but began to rise again in March 1974. Total travel in the seven months through June 1974 decreased by 3.5 percent; traffic increased by …

Skid Resistance Studies In Kentucky (An Overview – 1974), James H. Havens, James L. Burchett, Rolands L. Rizenbergs

Kentucky Transportation Center Research Report

"To free Kentucky of slick roads" is the high goal toward which Kentucky has been striving since 1950's. A very capable fellow engineer used to say that there was more satisfaction in being able to take down a Slippery When Wet sign than in erecting one.

Considerable effort has been devoted to the development and adaptation of improved methods of skid resistance testing and to the standardization of testing devices (1, 2, 3, 4). Methods of tests have included the NCSA friction wheel (bicycle wheel), automobile deceleration, skewed-wheel (skewed front-wheels of an automobile), skidding automobile, and the skid-test …

The Interpretation Of Infrared And Raman Spectra Using Pattern Recognition, John Martin Comerford

Dissertations

An automatic classification of chemical compounds by computer processing of digitized spectral data is presented. The classification system is based on a branch of artificial intelligence known as supervised learning, and used binary linear classifiers to identify compounds as alcohols, esters, ethers, ketones or compounds containing double bonds.

Each of the 1117 spectra in volume one of Sadtler's Standard Raman Spectra was coded using a scale from 0 to 9 in the range from 4000 to 200 cm^-1. One hundred and twelve readings were taken on each spectrum. These data were then examined using pattern recognition techniques, and …

A Rock Classification Schema, Robert C. Deen, C. D. Tockstein, M. W. Palmer

Kentucky Transportation Center Research Report

The need for engineering data on earth materials for use in site selection, design, construction, and maintenance of major engineering structures is generally accepted. Probably the most pressing need is for such data to use in preliminary considerations of site selection and design alternatives. Maps and(or) surveys giving the areal distribution of earth materials and their characteristics, together with topographic maps available for many areas, would permit much preliminary work on engineering structures to be done without the engineer ever having to leave his office.

"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.

Reconstruction of KY …

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).

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 …

Industrialized-Subsidized Housing In The Hackensack Meadowlands, Andrew Carl Gildersleeve

Theses

New Jersey as well as the rest of the nation is beginning to feel the pinch of what has been termed the housing crisis. The products of the World War II baby-boom are now reaching the age where they require homes of their own, making the demand for good quality low-cost housing very high. At the same time, the demand for good public housing continues to grow and we are learning that our previous efforts in this field have been far from satisfactory.

In the course of this study I have looked into the possibilities of solving a portion of …

The Effect Of Dry-Blending High Density Polyethylene On Final Product Properties, Charles H. Klestadt

Theses

The incentives for Dry-Blending Polyethylenes of varying property type may be economic gain, improved product quality, or both. The manufacturers' latest mode of operation involves seeking to meet their customers' needs with a product line made by using one catalyst system and operating at maximum capacity, while varying the fewest possible control parameters. Off-spec materials and on-spec materials not fitting customers' requirements are two prime targets for additional profits with proper dry blending techniques. The approach used in solving the problem involved starting with an existing product line and converting these products into a number of experimental blends. The blends …

The model is used to compute cost differentials in transit system options. These alternatives of expanding, abandoning or modifying service depend upon the service frequency, fleet size and other system attributes …

Design For A Developing Consortium, Henry A. Mauermeyer

Theses

The number of consortia in American higher education expanded rapidly from only ten in 1960 to eighty in 1973. Many do not have an organized method of developing interinstitutional cooperation, structuring their internal management, or preparing to meet future expansion.

The design of an organizational process appropriate to consortia in general has been developed in this thesis. The design is based on an analysis of various materials: (1) literature on the consortium movement; (2) data gathered from a nationwide survey conducted by the author; (3) visits with directors of consortia and experts in the consortium field; (4) actual working experience …

The Design And Implementation Of A Time-Shared Computer Based Construction Cost Estimating System For An Electric Utility, Thomas Arnold Westphal

Theses

The work of the distribution department of an elec tric utility involves a great deal of medium to heavy construction. This work is vital to serve the energy needs of the public. An electric utility constantly builds, reinforces, and repairs electric distribution facilities. The material and labor used to accomplish this construction is expensive. Money in sufficient amounts is seldom, if ever, available to finance all proposed construction projects. Therefore, the cost of proposed projects must be estimated in advance, so that management may decide on an economic basis which projects will be authorized.

The need for accurate construction cost …

Design Of Multipass Fractionating Trays, Paul W. Becker

Theses

Multipass fractionating trays are vapor-liquid contacting devices with high liquid handling capabilities which can be economically used in large fractionating towers. However, process design engineers in the chemical and petroleum industries seem to have an aversion to specifying multipass trays for their tower designs. This thesis presents the case for using multipass trays as well as methods for their design.

Because multipass trays are not symmetrical, as one and two pass trays are, the liquid and vapor need not split equally between the three or four passes. Equations are developed which enable the vapor and liquid flowrate for each pass …

An Evaluation Of In-Stream Structures Designed To Provide Fish Habitat, Charles H. Call Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In-stream concrete structures were studied through model tests and river tests. The model studies indicated that four designs provided good habitat in the model stream. These structures were the inverted weir, the "V" structure, the slab with legs and the cylinder. Through the river studies it was determined that these structures did not influence enough of the total river area to be effective in providing good fish habitat. Also an appreciable amount of yearly maintenance would be required to free the structures from silting in, debris, and vandalism. The slab with legs was the only promising structure.

Finite Difference Solution For Drainage Of Heterogeneous Sloping Lands, Fahd Salih Natur

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The two-dimensional problem of tile drainage on sloping heterogeneous lands was considered. The land surface and the impermeable boundaries of the problem were of a general shape. The flow in both the saturated and unsaturated zones was considered and the system was treated as one composite system. The problem was solved by a finite difference numerical method using the successive over-relaxation iterative (SOR) method for the steady state case with no local recharge, and a combined Newton inner iteration and successive over- relaxation outer iteration for the transient state case with local recharge. Both the rising water table and the …

Phosphorus Budget Of The Hyrum Reservoir - Little Bear River System, William A. Luce

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Phosphorus concentrations in the water of the Hyrum Reservoir - Little Dear River Watershed were determined by collecting 12 samples every two weeks over a seven month period and analyzing them for dissolved orthophosphate, total dissolved phosphorus, and total unfiltered phosphorus.

The concentrations obtained were used in conjunction with a water budget to determine a phosphorus budget. Apparent major inputs of phosphorus to the reservoir included a trout farm and runoff from agricultural land in the watershed.

Statistical analyses of the data were made to determine what effect precipitation, streamflow, and mileage downstream had on the concentrations of phosphorus in …

Operational Characteristics Of Lane Drops, Don L. Cornette, Robert C. Deen, James H. Havens

Kentucky Transportation Center Research Report

Traffic behavior studies were conducted at seven lane-drop locations, representing three lane-drop classes. These studies consisted of conflict observations (that is, erratic movements and brakelight applications), spot-speed observations, and lane volume counts. Such a study was made before and after each different traffic control device installation in an attempt to determine which device was the most effective in minimizing conflicts at existing lane drops. A study of conflict deviations indicates that no single type of traffic control device studied was significantly effective in reducing erratic movement and brakelight rates at all seven lane-drop locations. Rather, it appears that different traffic …
