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 …

Automation And Standardization Of Measuring Moisture Content And Density Of Soil Using The Technique Of Time Domain Reflectometry, Wei Feng, Chih-Ping Lin, Richard J. Deschamps, Vincent P. Drnevich

JTRP Technical Reports

The methodology developed by Siddiqui and Drnevich (1995) for measuring soil water content and density using Time Domain Reflectometry (TDR) was extended for routine use in the quality control testing of compacted soils. The objectives of the study were to develop computer software to automate data interpretation and data reduction, develop prototype equipment for field use, compare the results of the TDR method with the sand cone and nuclear density methods on actual construction sites and develop draft specifications for ASTM and AASHTO. New prototype equipment was developed for compaction quality control testing. Waveform interpretation and data reduction were automated …

Supremum Distribution Of Gaussian Processes And Queueing Analysis Including Long-Range Dependence And Self-Similarity, Jinwoo Choe, Ness B. Shroff

Department of Electrical and Computer Engineering Technical Reports

In this report we study the supremum distribution of a general class of Gaussian processes {Xt : t 2 0) having stationary increments. This distribution is directly related to the steady state queue length distribution of a queueing system, and hence its study is also important for various applications including communication network analysis. Our study is based on Extreme Value Theory and we show that log P({s~p~X:>t ~> x)) + asymptotically grows at most (on the order of) log x, where m, corresponds to the reciprocal of the maximum (normalized) variance of Xt. This result is considerably stronger than …

Strategic Planning For Activation And Operation Of The North Central Superpave Center (Ncsc): Interim Report, Jan Olek, Rebecca Mcdaniel

JTRP Technical Reports

The North Central Superpave Center (NCSC) was established to serve the needs of the states and industry in ten states and two Canadian provinces as they implement the Superpave system. Accomplishing this goal requires the cooperation and active support of a number of people and organizations. Organizational and operational issues related to infrastructure, personnel, equipment and finances also needed to be resolved. This project was designed to address those issues, develop a comprehensive strategic plan and initiate a number of activities of the North Central Superpave Center (NCSC).

This report summarizes the efforts in the following areas:

1 . Personnel …

On The Suprema Distribution Of Gaussian Processes With Stationary Increment And Drift, Jinwoo Choe, Ness B. Shroff

Department of Electrical and Computer Engineering Technical Reports

In this report we study the suprema distribution of a class of Gaussian processes having stationary increments and negative drift using key results from ~Txtrerne Value Theory. We focus on deriving an asymptotic upper bound to the tail of the suprema distribution of such processes. Our bound is valid for both discrete- and continuous-time processes. VVe discuss the importance of the bound, its applicability to queueing problems, and show numerical examples to illustrate its performance.

New Bounds And Approximations Using Extreme Value Theory For The Queue Length Distribution In High-Speed Networks, Jinwoo Choe, Ness B. Shroff

Department of Electrical and Computer Engineering Technical Reports

Statistical multiplexing is very important in high-speed ATM type of networks, since it allows applications to efficiently share valuable network resources. However, statistical multiplexing can also lead to congestion which must be effectively controlled in order to provide users satisfactory quality of service. In this report we study a fundamental measure of network congestion, the tail of the steady state queue length distribution at an ATM multiplexer. In particular, we focus on the case when the aggregate traffic to the multiplexer can be characterized by a Gaussian process. In our approach, an ATM multiplexer is modeled by a fluid queue …

Posteriori Probability Estimation And Pattern Classification With Hadamard Transformed Neural Networks, Peter G. Gulden, Okan Ersoy

Department of Electrical and Computer Engineering Technical Reports

Neural networks, trained with the backpropagation algorithm have: been applied to various classification problems. For linearly separable and nonseparahle problems, they have been shown to approximate the a posteriori probability of an input vector X belonging to a specific class C. In order to achieve high accuracy, large training data sets have to be used. For a small number of input dimensions, the accuracy of estimation was inferior to estimates using the Parzen density estimation. In this thesis, we propose two new techniques, lowering the mean square estimation error drastically and achieving better classification. In the past, t:he desired output …
