The Burdens Of Capability, Jean P. Peterson

Department of Educational Studies Faculty Publications

I once specialized in counseling talented and gifted children. Before that, I taught these students in my high school English classes for many years, and they taught me about themselves through their writings and discussions. Motivated by what I had learned from my most memorably talented students, I began discussion groups for them when I became a "gifted education teacher" in the 1980s. I knew there was a need for affective support. I also knew that educators, coaches, and even parents sometimes forgot that these bright and complex students were more than just potential fulfillers of adults' dreams, more than …

Development Of A 3-D Finite Element Program For Pavement Analysis, Volume I: Introduction And Appendix 1, 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 ¶metric 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 …

An Integrated Transportation Use Modeling System For Indiana, Andrew Ying-Ming Yen, Jon D. Fricker

JTRP Technical Reports

The principle objective of this research was to develop an integrated model to represent the interrelationships between land use and transportation, subject to the requirements of the ISTEA of 1991 and the CAAA of 1990. The integrated model includes two major parts: a land-use allocation module and a travel demand module. An interface module has also been built to transform data between these two modules. The land-use allocation module consists of a residential location model, an employment location model, a land use potential model, and a land consumption model. One unique feature of the residential and employment location models is …

Strength And Durability Of Concrete: Effects Of Cement Paste-Aggregate Interfaces, Part Ii: Significance Of Transition Zones On Physical And Mechanical Properties Of Portland Cement Mortar, Turng-Fang F. Lee, Menashi D. Cohen

JTRP Technical Reports

This research was based on a two-part basic research investigation studying the effects of cement paste-aggregate interfaces (or interfacial transition zones-HZ) on strength and durability of concrete. Part I dealt with the theoretical study and Part II dealt with the experimental. Part I, the theoretical part, illustrates the effect of ITZ on the concrete properties by assuming its elastic moduli to be varied continuously in the region. A four-phase composite model is employed and three functions are chosen to model the moduli variation in the ITZ. A theoretical solution for an n-layered spherical inclusion model is used to estimate the …

Integration Of Real-Time Air Pollution Parameters Into The Decision Making Process Regarding Highway Construction Work Zone Traffic Flow Requirements (Phase 1), Ouattara Fatogoma, Todd A. Premo, Robert Bertram Jacko

JTRP Technical Reports

The Midac Fourier Transform Infrared air monitoring system was used to measure real-time vehicular exhaust emission concentrations of carbon monoxide (CO) and hydrocarbons (HCs) during the Purdue Vehicle Emission Monitoring and Modeling Project (PVEMP) conducted in spring and summer 1997. The experiments took place on the Borman Expressway, in Gary. Indiana and on 1-65, south of Lafayette, Indiana Concurrently, two speed-readings were acquired from the passing vehicles in the vicinity of the air monitoring system using a hand-held laser gun. The speeds were integrated to determine the speeds and accelerations of the passing vehicles at the spectrometer. An 8-mm camcorder …

Modeling And Optimization Of The Indiana Lane Merge Control System On Approaches To Freeway Work Zones, Part I, 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: …

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 …
