Development Of A 3-D Finite Element Program For Pavement Analysis, Volume 2: Appendix 2, Tatsaba Nilaward, Chiang Shih, Thomas D. White, E. C. Ting

JTRP Technical Reports

A three dimensional finite element program is developed for the analysis of pavement systems. An explicit approach of the finite element analysis is adopted. This approach results in a vector formulation of the equation of motion. Large displacement is considered through the use of a co-rotational approach which considers small deformations and large rotations of the elements. For the convenience of application a two dimensional finite element program is also developed. An eight-node isoperimetric solid element is used for the three dimensional analysis, and a four-node element for the two dimensional analysis. Loading conditions are verified for static ramp and …

Geotechnical Performance Of Highway Embankment Constructed Using Waste Foundry Sand, Patrick J. Fox, David G. Mast

JTRP Technical Reports

The purpose of this study was to evaluate the use of waste foundry sand (WFS) as a highway embankment material in a fullscale field demonstration project. This evaluation included geotechnical concerns, such as deformation, strength, hydraulic conductivity, and ease of construction. The report presents an introduction and previous research concerning WFS use in highway construction. A geotechnical laboratory testing program characterized the WFS used in the project, which was a waste product of Auburn Foundry, Inc., located in Auburn, Indiana. This study was also a part of the FHWA Priorities Technology Program. The project site was a 275 m section …

Identification And Quantification Of Radionuclides In Coal Ash, James E. Alleman, Franklyn M. Clikeman, Thomas Skronski

JTRP Technical Reports

One of the important environmental issues raised recently in regard to coal ash reuse for highway construction purposes (e.g., embankment development) is that of worker, and public, exposure to radiation which might possibly be emitted by these types of residuals. Radiation emission is, in fact, a natural phenomenon for most materials, both natural and man-made, but in the case of coal ash residuals the process of combustion produces an inevitable concentration of radionuclides from the original virgin coal. INDOT’s corresponding environmental concern consequently focuses on the following basic question: does this magnification of radionuclides found within these coal ash residuals …

Modeling And Optimization Of The Indiana Land Merge Control System On Approaches To Freeway Work Zones, Part I: Implementation Report; Part Ii: Manual Of The Indiana Lane Merge Control System (2 Volumes), Andrzej P. Tarko, Sreenivasulu R. Kanipakapatnam, Jason S. Wasson

JTRP Technical Reports

Severe traffic turbulence on entry sections of freeway work zones increases the delays and risk of crash. A new Indiana Department of Transportation system called Indiana Merge Lane System (IMLS) creates a dynamic no passing zone on the approach to the freeway work zone through the sequence of DO NOT PASS signs. The system is thought to encourage drivers to switch lanes well upstream of the discontinuous lane taper where the merging maneuver is safer and less intrusive. The IMLS is expected to impact drivers’ behavior, their perception of the traffic conditions, and traffic safety. This research is focused on: …

Performance Evaluation Of A Highway Embankment Constructed Using Waste Foundry Sand, Barry K. Partridge, James E. Alleman

JTRP Technical Reports

Over 9 million Mg of waste foundry sands (WFS) are produced annually in the United States as a by-product of the metal casting industry. The majority of WFS are deposited in restricted or sanitary waste landfills. Considerable savings is available to the metal casting industry through the development of reuse applications for their WFS and generators are often willing to provide WFS to a job site at no cost to the end user. Laboratory investigations have indicated that WFS from ferrous foundries can provide the necessary engineering properties for a highway embankment and that the MicrotoxTM bioassay test can be …

Sensory Changes In Adults With Unilateral Transtibial Amputation, Judith B. Kosasih, Barbara Silver-Thorn

Biomedical Engineering Faculty Research and Publications

The purpose of this study was to describe the sensory changes in adults with unilateral transtibial amputation

(TTA), as any loss of sensation may have significant impact on the successful use of a prosthesis. Sensory modalities of light touch, deep pressure, vibration, and superficial pain (pinprick) were examined on the residual and contralateral limbs of 16 veterans with TTA. Six subjects demonstrated normal sensation on the contralateral limb and impaired sensation of superficial pain, vibration, and/or light touch on the residual limb. Superficial pain was the most frequently impaired sensation, and vibration and superficial pain sensation appeared to be age-dependent, …

Integrating Security Into The Curriculum, Cynthia E. Irvine, Shiu-Kai Chin, Deborah Frincke

Electrical Engineering and Computer Science - All Scholarship

The number of skilled practitioners of computer security who are able to address the complexities of modern technology and are familiar with successful approaches to system security is very small. People want security but are faced with two difficulties. First, they do not know how to achieve it in the context of their enterprises. They may not even know of a way to translate organizational procedures into policies, much less implement a set of mechanisms to enforce those policies. Second, they have no way of knowing whether their chosen mechanisms are effective. The recent US Presidential Commission on Critical Infrastructure …

Nitrogen Transformations In Coal During Pyrolysis, Simon R. Kelemen, Martin L. Gorbaty, P J. Kwiatek, Thomas H. Fletcher, Mathew Watt, Mark S. Solum, Ronald J. Pugmire

Faculty Publications

X-ray photoelectron spectroscopy (XPS) was used to identify and quantify the changes in organically bound nitrogen forms present in the tars and chars of coals after pyrolysis. For fresh coal, pyrrolic nitrogen is the most abundant form of organically bound nitrogen, followed by pyridinic, quaternary, and amino types. Some of the quaternary nitrogen species initially present in coal are lost upon mild pyrolysis, prior to hydrocarbon devolatilization. These quaternary species are attributed to pyridinic or basic nitrogen species associated with hydroxyl groups from carboxylic acids or phenols. A portion of the quaternary nitrogen species is lost at the very earliest …
