The Effects Of Bag House Fines And Incomplete Combustion Products In A Drum Drier On The Characteristics Of Asphalt Paving Mixtures, Phase Ii, Jyh-Dong Lin, Leonard E. Wood

JTRP Technical Reports

An extensive laboratory study of the asphalt paving mixtures containing baghouse fines has been conducted through seven sets of experimental designs to characterize the performance of pavement. Marshall size specimens of asphalt paving mixtures with different kinds and amounts of baghouse fines were fabricated using the gyratory testing machine. The following techniques were used to evaluate the influence of the various variables upon mechanical properties such as: gyratory parameters, resilient modulus, indirect tensile strength, indirect creep, and Hveem stability tests to evaluate their mechanical properties. In addition, in the asphalt paving mixtures, asphalt cement was replaced with baghouse fines in …

The Physical Durability And Electrical Resistivity Of Indiana Bottom Ash, Te-Chih Ke

JTRP Technical Reports

This research assessed the long-term performance (durability) and the environmental effect (corrosiveness to adjacent metal structures) of Indiana bottom ashes, based mainly on laboratory investigation. The 5-cycle sodium sulfate soundness tests and the 50-cycle freeze-thaw tests were conducted to examine the physical durability. Four electrochemical characteristics (electrical resistivity, pH, soluble chloride, and soluble sulfate) were used to estimate the corrosion potential of Indiana bottom ashes.

Evaluation criteria for durability and corrosiveness of bottom ash, based on appropriate specifications for aggregates and past experiences for soils, were developed. The comparison of test results and the above criteria shows that Indiana bottom …

Evaluation Of The Cost-Effectiveness Of Pavement Surface Maintenance Activities, Ibrahim Moussa Mouaket, Abdullah Al-Mansour, Kumares C. Sinha

JTRP Technical Reports

This study covers pavement surface maintenance on three surface types: rigid, flexible and composite (asphalt overlay on rigid pavement). It addresses 3 main issues as follows: 1) Do routine maintenance activities make a difference in terms of pavement serviceability? If yes, how much? 2) Are chip and sand seal coating cost-effective? What is their optimal timing? 3) What management criteria should be used as a guide to make seal coating decisions on specific roadways? In resolving Issue #1, a stratified 2-stage sample of observational data was used in a statistical before/after comparison. SAS-General Linear Model was used due to its …

On The Average-Case Running Time Of The Boyer-Moore Algorithm, Russell W. Quong

Department of Electrical and Computer Engineering Technical Reports

The Boyer-Moore algorithm (BM) is a fast, compact algorithm for finding all occurrences of a pattern string in a text string. Previous papers have addressed the worst-case running time of BM, which occurs rarely in practice. In this paper, we derive an approximation to Φ (BM) the average number of character probes made by BM. Let M = pattern length, N = text string length, α = the alphabet size, q = 1 /α and q= I — q. By modeling BM as a probabilistic finite automaton, we show that Φ(BM) h when M < α and that Φ(BM ) N q(l + g V ) when M > α. An immediate consequence is that …

Robust Techniques For Bearing Estimation In Contaminated Gaussian Noise, R. L. Kashyap, David D. Lee, N. Srinivasa

Department of Electrical and Computer Engineering Technical Reports

The problem of estimating directions-of-arrival (DOA) of radiating sources from measurements provided by a passive array of sensors is frequently encountered in radar, sonar, radio astronomy and seismology. In this study various robust methods for the DOA estimation problem are developed, where the term robustness refers to insensitivity against small deviation in the underlying Gaussian noise assumption. The first method utilizes an eigenvector method and robust reconstruction of the correlation matrix by time series modeling of the array data; Secondly, a decentralized processing scheme is considered for geographically distributed array sites. The method provides reliable estimates even when a few …

Simulation Of Heterojunction Bipolar Transistors In Two Dimensions, Paul Emerson Dodd

Department of Electrical and Computer Engineering Technical Reports

This work describes the formulation and, development of a two-- dimensional drift-diffusion simulation program for accurate modeling of heterojunction bipolar transistors (HBT's). The model described is a versatile tool for studying HBT's, allowing the user to determine the terminal characteristics and physical operation of devices. Nonplanar structures can be treated, response to transient conditions can be computed, and the high frequency characteristics of transistors may be projected. The formulation of an electron energy balance equation is presented and included in the model in an attempt to more accurately compute high-field transport characteristics. The model is applied to some common design …
