Use Of Modulus Of Rupture, Fatigue Resistance And Maturity In Determining Opening To Traffic Time For Concrete Pavements, J. Olek, Menashi D. Cohen, Charles F. Scholer, Deepak R. Mandrekar

JTRP Technical Reports

The main objective of this experimental and analytical research project was to develop maturity-based guidelines for early opening-to-traffic of concrete pavements in the state of Indiana. Currently, the Indiana Department of Transportation (INDOT) specifies that pavements can be opened to traffic when the concrete reaches the strength of at least 3.8 MPa (550 psi). During this study modulus of rupture (MOR) and maturity data were collected and strength gain characteristics were analyzed. Also, fatigue experiments were performed at different stress levels and ages. Based on the experimental results, modulus of rupture of concrete was correlated with corresponding fatigue life for …

Locked In Inequality: The Persistence Of Discrimination, Daria Roithmayr

Michigan Journal of Race and Law

In this Article, the author argues that the practice of charging school fees to attend public school is an example of locked-in discrimination that persists over time, even in the absence of intentional discrimination. Exploring the lock-in model of discrimination in the unique context of South Africa, Roithmayr makes two central points. First, discriminatory practices often become locked into institutional structures because high switching costs-the costs of moving from a discriminatory practice to an inclusive one—make it too difficult for an institution to discontinue discriminating. Even when institutional actors are fully committed to eradicating racial disparity, they may be constrained …

The Role Of Temperature In Testing Deep Submicron Cmos Asics, Ethan Schuyler Long

Dissertations and Theses

Among the many efforts to improve the IC test process are tests that attempt to differentiate between healthy and defective or low reliability ICs by manipulating the operating conditions of the IC being tested. This thesis attempts to improve the common understanding of multiple and targeted temperature testing by evaluating work published on the subject to date and by presenting previously unpublished empirical observations. The empirical observations are made from SCAN and LBIST based MinVDD measurements, Static IDD measurements, as well as parametric measurements of transistor characteristics. The test vehicles used are 0.25μm and 0.18μm CMOS ASICs fabricated by LSI …

Thrombus Formation: Direct Real‐Time Observation And Digital Analysis Of Thrombus Assembly In A Living Mouse By Confocal And Widefield Intravital Microscopy, A. Celi, G Merrill-Skoloff, P. Gross, Shahrokh Falati, D. S. Sim, R. Flaumenhaft, B. C. Furie, B. Furie

Articles & Chapters

We have developed novel instrumentation using confocal and widefield microscopy to image and analyze thrombus formation in real time in the microcirculation of a living mouse. This system provides high-speed, near-simultaneous acquisition of images of multiple fluorescent probes and a brightfield channel, and supports laser-induced injury through the microscope optics. Although this imaging facility requires interface of multiple hardware components, the primary challenge in vascular imaging is careful experimental design and interpretation. This system has been used to localize tissue factor during thrombus formation, to observe defects in thrombus assembly in genetically altered mice, to study the kinetics of platelet …

Development Of An Aggregation Methodology For Risk Analysis In Aerospace Conceptual Vehicle Design, Trina Marsh Chytka

Engineering Management & Systems Engineering Theses & Dissertations

The growing complexity of technical systems has emphasized a need to gather as much information as possible regarding specific systems of interest in order to make robust, sound decisions about their design and deployment. Acquiring as much data as possible requires the use of empirical statistics, historical information and expert opinion. In much of the aerospace conceptual design environment, the lack of historical information and infeasibility of gathering empirical data relegates the data collection to expert opinion.

The conceptual design of a space vehicle requires input from several disciplines (weights and sizing, operations, trajectory, etc.). In this multidisciplinary environment, the …

[Introduction To] By The Hand Of Mormon: The American Scripture That Launched A New World Religion, Terryl Givens

Bookshelf

With over 100 million copies in print, the Book of Mormon has spawned a vast religious movement, but it remains little discussed outside Mormon circles. Now Terry L. Givens offers a full-length treatment of this influential work, illuminating the varied meanings and tempestuous impact of this uniquely American scripture.

Givens examines the text's role as a divine testament of the Last Days and as a sacred sign of Joseph Smith's status as a modern-day prophet. He assesses its claim to be a history of the pre-Columbian peopling of the Western Hemisphere, and later explores how the Book has been defined …

An Experimental Study Of Flow Control Techniques On A Multi-Element Airfoil, Ira James Walker

Mechanical & Aerospace Engineering Theses & Dissertations

The results of a wind tunnel experiment are reported, which investigated two different flow control techniques that demonstrated the potential of increasing the lift coefficient on a multi-element airfoil. The data also indicated that boundary-layer separation on the trailing-edge flap could be reduced significantly. Results of the investigation revealed that for some test conditions an increased amount of suction occurred on the upper surface of the main element where the flow was attached. One of the techniques that was tested in this investigation involved the use of a pair of piezoelectric devices attached to the model to provide oscillatory motion …

Numerical Study Of Two-Dimensional Secondary Injection Into A Mach 3.5 Freestream, Stephen C. Coghill

Mechanical & Aerospace Engineering Theses & Dissertations

Upstream interaction within a dual-mode scramjet engine is investigated numerically. The upstream interaction is investigated by increasing the freestream-to-injector pressure ratio. The constant area duct and sudden expansion geometries are used to achieve these results. Analysis using the symmetry boundary condition is compared to the full boundary condition for the constant area duct. Numerical analysis of the Mach 3.5 freestream is conducted using normal sonic injection of nitrogen gas to create the upstream interaction. Comparisons, where applicable, are made to experimental results. Due to the high speed of the flowfield, oblique shockwaves are present causing numerical convergence difficult to achieve. …

Two-Dimensional Numerical Simulation And Design Of Fully Grouted Bolts For Underground Coal Mines., Asmaa Mohamed Yassien

Graduate Theses, Dissertations, and Problem Reports (ETD)

The fully grouted bolt is a passive support. It occupied the greatest portion of the annual roof bolt consumption in the U.S. There are three components of the fully grouted bolt; steel rebar (bolt), resin annulus, and rock/grout interaction. Fully grouted bolts are loaded in three ways: axial load, shear load and bending moment. Moreover, vertical shear stress is developed along the grout/rock interface. Using ABAQUS 5.8, finite element models were developed to simulate the components of the fully grouted bolt and its interaction with the surrounding roof strata. Several models were conducted in order to investigate the effect of …

Three-Dimensional Numerical Simulation And Design Of Tensioned Roof Bolting For Underground Coal Mines., Yunqing Zhang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Tensioned bolts work in different mechanisms from the fully grouted resin bolts and are believed to be effective for certain types of roof strata. A 3-D finite element model using ABAQUS has been developed for the tensioned bolting design. In this model, the physical process of the tensioned bolting including entry excavation sequence, roof bolting components, bolt installation procedure and pre-tension is modeled realistically. Bedding planes and in-situ horizontal stresses are also considered in the model. A case study of a well-instrumented intersection of entry/crosscut was used to compare the results from the modeling with field measurements in terms of …

Linking Intellectual Property Rights In Developing Countries With Research And Development, Technology Transfer, And Foreign Direct Investment Policy: A Case Study Of Egypt's Pharmaceutical Industry, Sahar Aziz

Faculty Scholarship

This Note focuses on TRIPS' impact on the pharmaceutical industry as well as health care in developing nations. By using Egypt as a case study, this Note aims to emphasize that the benefits of TRIPS for developing nations depends on the linkage between intellectual property rights (IPR) and other legal regimes, particularly drug regulation, technology transfer, and foreign direct investment (FDI) policies. The failure to adopt a holistic approach to the creation of effective and beneficial intellectual property rights regimes will merely increase the western pharmaceuticals' market share and increase drug prices in developing nations.6 By asking whether Egypt, versus …

Highways Of The Mind: The Haunting Of The Superhighway From The World's Fair To The World Wide Web., Helen J. Burgess

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation investigates the way in which the rhetorical construction of the highway has been haunted, first by narratives of promise and progress and then of decay and death. Highways are figured as technological wonders marking the advent of a better future in the 1939 World's Fair and the advertising campaigns of the 1950s, and then as wired-up networks of death in science fictional accounts from the 60s to the 90s. At stake in this project is the very status of metaphor in the analysis of technology. The highway is a compelling 20th-century metaphor that reveals anxieties we have about …

Development Of A Regional Curve To Relate Discharge And Drainage Area To Hydraulic Geometry For The Red River Of The North Basin, Melanie H. Johnson

Theses and Dissertations

Restoration of riparian corridors and stream channels is important for many reasons, including preserving water quality, maintaining channel stability and controlling floods. Regional hydraulic geometry curves allow estimation of stable hydraulic geometry relationships that are necessary to engineer successful restoration projects. These curves can also be used to approximate discharge data for ungaged streams with lmown hydraulic geometry and drainage area. Hydraulic geometry data were collected in the field for twenty-five stream gage sites in the Red River of the North Basin. Recurrence intervals for bankfull ranged from 1.2 to 1.6 years, with an average recurrence interval of 1.4. Discharge …
