State Traffic Volume Systems Count Estimation Process, Doug Kreis, Angie Quigley

Kentucky Transportation Center Research Report

The Kentucky Transportation Cabinet has an immense traffic data collection program that is an essential source for many other programs. The Division of Planning processes traffic volume counts annually. These counts are maintained in the Counts Database (CTS), which contains over 20,000 separate station locations and some traffic counts from as early as 1963.

The Division of Planning currently collects traffic volume counts for all non-interstate routes on a revolving three year basis. Years wherein actual counts are not performed are supplemented with estimates generated by a FORTRAN program. Estimates are projected using prior actual counts by weighted linear regression …

System For Valuing Changes To Historic And Environmental Amenities, Eric C. Thompson, Jennifer M. Burnett, Anna L. Stewart

Kentucky Transportation Center Research Report

This model provides a tool that transportation officials can use to examine any project’s impact on historic or environmental amenities.

The model allows transportation officials to design their analysis for a particular highway project. Officials simply select the …

Using Wind To Power A Groundwater Circulation Well—Preliminary Results, Andrew Curtis Elmore, Ron Gallagher, K. David Drake

United States Environmental Protection Agency: Publications

In areas of the country where the U.S. Department of Energy has classified the available wind resources as Class 3 or greater, the use of wind turbines to provide power to relatively small remediation systems such as groundwater circulation wells may be technically and economically feasible. Groundwater circulation wells are a good candidate technology to couple with renewable energy, because the remediation system removes contamination from the subject aquifer with no net loss of the groundwater resource, while the wind turbine does not create potentially harmful air emissions. Wind data collected in the vicinity of the former Nebraska Ordnance Plant …

Cs 410/610: Theoretical Foundations Of Computing, Thomas Sudkamp

Computer Science & Engineering Syllabi

This course is an introduction to one of the fundamental topics in the theory of computer science: computability theory. Computability theory is concerned with determining whether there is an algorithmic solution to a problem. The study of computability uses the Turing machine as the basic computational model. A Turing machine is a random access, read-write, finite state automaton. The Church-Turing thesis asserts that any problem that can be solved in any algorithmic manner can be solved by a Turing machine.

Eaf Voltage Flicker Mitigation By Facts/Ess, Li Zhang, Yilu Liu, Michael R. Ingram, Dale T. Bradshaw, Steve Eckroad, Mariesa Crow

Electrical and Computer Engineering Faculty Research & Creative Works

One of the problems caused by an electrical arc furnace (EAF) is voltage fluctuation from the variations of the active and reactive furnace load, which are known as voltage flickers. In this paper, voltage flicker mitigation results by different FACTS and energy storage systems (ESS) were presented. The system X/R ratio looking from the point of common coupling, which has a special impact on the effectiveness of active compensation, was discussed. The study has clarified the misunderstanding of how the system X/R ratio should be calculated. The study showed that FACTS with ESS could play a better role than reactive …

Evaluating Conduction Loss Of A Parallel Igbt-Mosfet Combination, Jonathan W. Kimball, Patrick L. Chapman

Electrical and Computer Engineering Faculty Research & Creative Works

A variety of power devices are available to designers, each with specific advantages and limitations. For inverters, typically an IGBT combined with a p-i-n diode is used to obtain high current density. Recent developments in high-voltage MOSFETs support other alternatives. For example, a MOSFET can be paralleled with an IGBT to reduce losses at low currents, while the IGBT carries the load at high currents. The current work evaluates conduction losses in this configuration, showing applicability to generic inverters.

Landmine Detection And Discrimination Using High-Pressure Waterjets, Daryl G. Beetner, R. Joe Stanley, Sanjeev Agarwal, Deepak R. Somasundaram, Kopal Nema, Bhargav Mantha

Electrical and Computer Engineering Faculty Research & Creative Works

Methods of locating and identifying buried landmines using high-pressure waterjets were investigated. Methods were based on the sound produced when the waterjet strikes a buried object. Three classification techniques were studied, based on temporal, spectral, and a combination of temporal and spectral approaches using weighted density distribution functions, a maximum likelihood approach, and hidden Markov models, respectively. Methods were tested with laboratory data from low-metal content simulants and with field data from inert real landmines. Results show that the sound made when the waterjet hit a buried object could be classified with a 90% detection rate and an 18% false …

Probabilistic Balancing Of Fault Coverage And Test Cost In Combined Built-In Self-Test/Automated Test Equipment Testing Environment, Shanrui Zhang, Minsu Choi, Nohpill Park, Fabrizio Lombardi

Electrical and Computer Engineering Faculty Research & Creative Works

As design and test complexities of SoCs ever intensify, the balanced utilization of combined built-in self-test (BIST) and automated test equipment (ATE) testing becomes desirable to meet the required minimum-fault-coverage while maintaining an acceptable cost overhead. The cost associated with combined BIST/ATE testing of such systems mainly consists of 1) the cost induced by the BIST area overhead and 2) the cost induced by the overall testing time. In general, BIST is significantly faster than ATE, while it can provide only limited fault-coverage, and driving higher fault-coverage from BIST means additional area cost overhead. On the other hand, higher fault-coverage …

Multi-D Cfd Modeling Of Free-Piston Stirling Convertor At Nasa Grc, Scott D. Wilson, Rodger W. Dyson, Roy C. Tew, Mounir B. Ibrahim

Mechanical Engineering Faculty Publications

A high efficiency Stirling Radioisotope Generator (SRG) is being developed for possible use in long duration space science missions. NASA s advanced technology goals for next generation Stirling convertors include increasing the Carnot efficiency and percent of Carnot efficiency. To help achieve these goals, a multidimensional Computational Fluid Dynamics (CFD) code is being developed to numerically model unsteady fluid flow and heat transfer phenomena of the oscillating working gas inside Stirling convertors. Simulations of the Stirling convertors for the SRG will help characterize the thermodynamic losses resulting from fluid flow and heat transfer between the working gas and solid walls. …

Sagittal Plane Biomechanics Cannot Injure The Acl During Sidestep Cutting, Scott G. Mclean, Xuemei Huang, Anne Su, Antonie J. Van Den Bogert

Mechanical Engineering Faculty Publications

Background. Knee joint sagittal plane forces are a proposed mechanism of anterior cruciate ligament injury during sport movements such as sidestep cutting. Ligament force magnitudes for these movements however, remain unknown. The need to examine injury-causing events suggests elucidation via model-based investigations is possible. Using this approach, the current study determined whether sagittal plane knee loading during sidestep cutting could in isolation injure the anterior cruciate ligament.

Methods. Experiments were performed on subject-specific forward dynamic musculoskeletal models, generated from data obtained from 10 male and 10 female athletes. Models were optimized to simulate subject-specific cutting movements. Random perturbations …
