The Physical Durability And Electrical Resistivity Of Indiana Bottom Ash : Executive Summary, 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 …

The Use Of Bottom Ash In Highway Embankments, Subgrades, And Subbases : Executive Summary, Wei-Hsing Huang

JTRP Technical Reports

This research assessed those properties of power plant bottom ash likely to affect its use as highway fill or pavement material, based on laboratory investigation conducted on eleven Indiana bottom ashes. Laboratory tests included: chemical analysis, mineralogical study, microscopic examination of ash particles, specific gravity, grain size distribution, sulfate soundness, Los Angeles abrasion, permeability, shear strength, moisture-density relations, degradation under compaction, compressibility, and California bearing ratio.

The various test values and properties were compared to- those of representative granular soils or appropriate specifications. These comparisons provide information necessary for judging the suitability of bottom ash in Indiana highway construction.

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 …

Basic Studies Of Iii-V High Efficiency Cell Components, M. S. Lundstrom, M. R. Melloch, R. F. Pierret, M. S. Carpenter

Department of Electrical and Computer Engineering Technical Reports

This project’s objective is to improve our fundamental understanding of the generation, recombination, and transport of carriers within III-V homo- and heterostructures. The research consists of fabricating and characterizing solar cell “ building blocks” such as junctions and heterojunctions as well as basic measurements of material parameters. A significant effort is also being directed at characterizing loss mechanisms in high-quality, III-V solar cells fabricated in industrial research laboratories throughout the United States. The project’s goal is to use our understanding of the device physics of high-efficiency cell components to maximize cell efficiency. A related goal is the demonstration of new …

Performance Analysis Of Hardware Barrier Synchronization, M. O'Keefe, H. Dietz

Department of Electrical and Computer Engineering Technical Reports

Synchronization among cooperating processors is a critical issue in the performance of high speed multiprocessors. For current Multiple Instruction stream Multiple Data stream (MIMD) computers synchronization cost is high. Hence, these architectures can execute only large granularity parallelism efficiently. In this report we study a new hardware synchronization technique, known as a hardware barrier. Machines using this technique are known as barrier MIMDs. Analytic and simulation studies are employed to show that hardware barrier synchronization can outperform the more common directed synchronization techniques. Barrier synchronization can be viewed as a static synchronization mechanism similar to the implicit synchronization of Very …

"If You Don't Like It, Neither Do I", Judith A. Myers-Walls

Historical Documents of the Purdue Cooperative Extension Service Archive

Most children do not know about, nor care about, "food value," "vitamins," "minerals," or "food groups,' making it important for parents to provide guidance to their children to help them eat right. This publication will explore the ways in which parents influence children's eating habits and suggest some specific techniques parents can use to guide children as they learn about nutrition. How can parents help children to appreciate and enjoy foods that are good for them?

Vision-Guided Mobile Robot Navigation, C. Lopez-Abadia, A. C. Kak

Department of Electrical and Computer Engineering Technical Reports

This report discusses the use of vision feedback for autonomous navigation by a mobile robot in indoor environments. In particular, we have discussed in detail the issues of camera calibration and how binocular and monocular vision may be utilized for self-location by the robot. A noteworthy feature of monocular vision is that the camera image is compared with a CAD model of the interior of the hallways using the PSEIKI reasoning system; this reasoning system allows the comparison to take place at different levels of geometric detail.

Changes In Expired End-Tidal Carbon Dioxide During Cardiopulmonary Resuscitation In Dogs: A Prognostic Guide For Resuscitation Efforts, Karl B. Kern, Arthur B. Sanders, William D. Voorhees, Charles F. Babbs, Willis A. Tacker, Gordon A. Ewy

Weldon School of Biomedical Engineering Faculty Publications

Expired end-tidal carbon dioxide (PCO2) measurements made during cardiopulmonary resuscitation have correlated with cardiac output and coronary perfusion pressure when wide ranges of blood flow are included. The utility of such measurements for predicting resuscitation outcome during the low flow state associated with closed chest cardiopulmonary resuscitation remains uncertain. Expired end-tidal PCO2 and coronary perfusion pressures were measured in 15 mongrel dogs undergoing 15 min of closed chest cardiopulmonary resuscitation after a 3 min period of untreated ventricular fibrillation. In six successfully resuscitated dogs, the mean expired end-tidal PCO2 was significantly higher than that in nine nonresuscitated dogs only after …

3d Location Of Circular And Spherical Features By Monocular Model-Based Vision, Y. C. Shiu, Shaheen Ahmed

Department of Electrical and Computer Engineering Technical Reports

This paper addresses the mathematics for using monocular model-based vision to find the 3-D positions of circular and spherical model features, and, for the circular case, orientations as well. Monocular model-based vision here refers to the use of a single projective image of modeled objects to solve for the 3-D positions and orientations of the objects in the scene. The mathematics for solving 3-dimensional position and orientation of the object from matched model and image points/lines features are well known. However, no known paper addresses spherical features arid very few papers address the mathematics involving circular model features. This paper …
