The Irrepressible Myth Of Marbury, Michael Stokes Paulsen

Michigan Law Review

Nearly all of American constitutional law today rests on a myth. The myth, presented as standard history both in junior high civics texts and in advanced law school courses on constitutional law, runs something like this: A long, long time ago - 1803, if the storyteller is trying to be precise - in the famous case of Marbury v. Madison, the Supreme Court of the United States created the doctrine of "judicial review." Judicial review is the power of the Supreme Court to decide the meaning of the Constitution and to strike down laws that the Court finds unconstitutional. As …

Investigation Of The Applicability Of Neural-Fuzzy Logic Modeling For Culvert Hydrodynamics, Jonathan M. Lester

Graduate Theses, Dissertations, and Problem Reports (ETD)

As a result of an earlier WV DOH study, the idea came to the forefront of using a completely new approach to analyzing the complex subject of culvert hydrodynamics. The literature indicates that there have been no reports of artificial intelligence, to include neural networks, fuzzy logic, or combined neural-fuzzy logic, used to investigate and predict culvert hydrodynamics.;The scope of this dissertation is to investigate the applicability of using neural-fuzzy logic to predict culvert diameters. To analyze these flows, commercial culvert software was employed to account for all types of flow conditions. This included different slopes, lengths, flow-rates, pipe sizes, …

Southworth, R. Wehlitz, J. Baker, A. C. Hudson, M. Lotrakul, D. Rolles, Wayne C. Stolte, I. Tran, A. Wolska, S. Yu, M. Ya Amusia, K. T. Cheng, L. V. Chernysheva, W. R. Johnson, S. T. Manson

Environmental Studies Faculty Publications

The Xe 5s nondipole photoelectron parameter γ is obtained experimentally and theoretically from threshold to ∼200  eV photon energy. Significant nondipole effects are seen even in the threshold region of this valence shell photoionization. In addition, contrary to previous understanding, clear evidence of interchannel coupling among quadrupole photoionization channels is found.

Effects Of Computer Troubleshooting On Elementary Students' Problem Solving Skills, Anne Todd Ottenbreit

Masters Theses

The lack problem solving skills exhibited by students has generated concerns at national and state levels of education (Coleman, King, and Ruth, 2001). If the educational technology curriculum involved computer troubleshooting, students could possibly increase their problem solving abilities. Because computer troubleshooting follows similar procedures to problem solving, there is possibility of an educational transfer and could be easily included into the educational technology curriculum. The purpose of the research study was to discover if the computer troubleshooting curriculum designed by the researcher affected the elementary students' problem solving abilities. Technology education at the elementary level includes keyboarding and 'practice …

Evaluation Of The Distribution Of Taguchi's Signal-To-Noise Ratio And The Effectiveness Of The Signal-To-Noise Ratio For Detecting Changes In The Mean And/Or Variance, Jinsuk Lee

Masters Theses

The concept of parameter design developed by Taguchi to achieve robust engineering is widely promoted in industry as a means to design a product whose output is largely immune to noise in the system. Taguchi has used the signal-to-noise (S/N) ratio to summarize measures over the noise factor settings at the parameter design and to allow control of the experiment.

The objectives of this investigation are: 1) to infer distributions of S/N ratios (lower-the-better S/N, higher-the-better S/N, and nominal-the-best SIN), and 2) to determine the effectiveness of the S/N ratio as a means for identifying changes in the mean and …

Electrical Conductivity Measurements Of Lithium-Ammonia Solutions, Mariana Constantin Barbu

Masters Theses

The topic covered in this thesis is the study of electronic interactions for liquid metal-ammonia solutions, lithium-ammonia solutions in particular. To obtain a theoretical understanding of so-called correlated electron systems.

The work focuses on sample creation and measurement of electrical conductivity of lithium-ammonia solutions varying with temperature for different concentrations. We have taken measurements in liquid lithium-ammonia mixtures using four-wire method to minimize the contact resistance. We have shown how it is possible to carry out accurate measurements of the electrical conductivity in these systems with the four wire measurements.

Application Of Geochemical Fingerprinting And Isotopes To Identity Landfill Gas Impacts To Groundwater, Eric E. Wallis

Masters Theses

Volatile organic compounds (VOCs) are detected in two groundwater monitoring wells (MW-60 and MW-62S) located along the northern, downgradient property line of the McGill Road Landfill (MRL) in Jackson, Michigan. Potential on-site sources for groundwater impact are two distinct landfill units at the MRL. Leachate chemistry suggested that landfill leachate was not the source of VOCs detected in groundwater. A potential source for VOCs was landfill gas. Sources of landfill gas in the vicinity of the impacted wells included the distinct MRL landfill units as well as the old Jackson County Landfill (JCL), located hydraulically downgradient from the impacted wells. …

Numerical Simulation For Parametric Study Of A Two -Stroke Compression Ignition Direct Injection Linear Engine, Ehab F. Shoukry

Graduate Theses, Dissertations, and Problem Reports (ETD)

A time based numerical simulation program was built at West Virginia University to simulate the operation of a two-stroke compression ignition direct injection linear engine. The two-stroke linear engine consists of two pistons connected together with a yoke and allowed to move freely according to the frequent combustion that takes place in response to fueling and load applied along the full stroke of the internal combustion engine. The simulating program used a series of dynamic and thermodynamic equations that were solved simultaneously to predict the performance and analyze the different factors affecting the operation of the two-stroke compression ignition linear …

Eulerian Subgraphs And Hamiltonicity Of Claw -Free Graphs, Mingquan Zhan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Let C(l, k) denote the class of 2-edge-connected graphs of order n such that a graph G ∈ C(l, k) if and only if for every edge cut S ⊆ E(G) with |S| ≤ 3, each component of G - S has order at least n-kl . We prove that If G ∈ C(6, 0), then G is supereulerian if and only if G cannot be contracted to K2,3, K 2,5 or K2,3(e), where e ∈ E(K2,3) and K2,3(e) stands for a graph obtained from K2,3 by replacing e by a path of length 2. Previous results by Catlin and …

Fast Wavelet Collocation Methods For Second Kind Integral Equations On Polygons, Yi Wang

Graduate Theses, Dissertations, and Problem Reports (ETD)

In this thesis we develop fast wavelet collocation methods for integral equations of the second kind with weakly singular kernels over polygons . For this purpose, we construct multiscale wavelet functions and collocation functionals having vanishing moments. Moreover, we propose several truncation strategies, which lead to fast algorithms, for the coefficient matrix of the corresponding discrete system. Critical issues for numerical implementation of such methods are considered, such as choices of practical truncation strategies, numerical integration of weakly singular integrals, error controls of numerical quadrature and numerical solutions of resulting compressed linear systems. Numerical experiments are given to demonstrate proposed …

A Re-Evaluation Of The Us Epa Radon Risk Categorization For Unicoi County, Tennessee., William Grant Parsons

Electronic Theses and Dissertations

Effective risk communication is based on appropriate risk characterization. A reevaluation of the 1987 US EPA radon risk categorization of Unicoi County Tennessee was conducted using in-home radon concentrations, determined in a long-term monitoring study. Radon concentrations were measured in 69 homes using Electret Passive Environmental Radon Monitors (E-PERM’s), following standard methods. Radon concentrations determined in this study (avg. 4.03 ± 3.04) were significantly higher than those measured in the USEPA study (avg. 1.96 ± 1.08). Using this study’s data, the risk categorization was recalculated with the US EPA Radon Index Matrix Model. The model re-categorized Unicoi County from a …

Mindful Communication In A Crisis: Communication Behaviors Of Shared Mindfulness And Effective Pilot Decision Outcomes In Crisis Situations, Janice L. Krieger

Masters Theses

Despite the high reliability of current aeronautical technology and safety improvements, human error continues to be a factor in 60-80% of all aviation mishaps. Training to diminish potential errors is often based on analysis of faulty procedures, or lack of procedures without a systemic view including human factors such as communication, decision-making and interaction dynamics. This research explores the existence of the psychological construct of shared mindfulness and examines how it is communicatively constructed and enacted in a high reliability environment such as the aviation industry. The present qualitative study examines shared mindfulness in 10 aviation student dyads in a …

Elastic Wave Propagation And Scattering In Solids With Uniaxially Aligned Cracks, Liyong Yang, Joseph A. Turner

Nebraska Center for Materials and Nanoscience: Faculty Publications

In this article, elastic wave propagation and scattering in a solid medium permeated by uniaxially aligned penny-shaped microcracks are studied. The crack alignment refers to the case in which the unit normals of all cracks are randomly oriented within a plane of isotropy. The analysis is restricted to the limit of the noninteraction approximation among individual cracks. Explicit expressions for attenuations and wave speeds of the shear horizontal, quasilongitudinal, and quasishear vertical waves are obtained using stochastic wave theory in a generalized dyadic approach. The ensemble average elastic wave response is governed by the Dyson equation, which is solved in …

Modelling The Tone Reproduction Characteristics Of Digital Printers Using Continuous Tone Model, Prashant Mehta

Theses

Traditional halftone models have been used to characterize the tone reproduction characteristics of digital printers. These models can be corrected to incorporate system parameters like light scattering, softer dot edge etc. This thesis work explores the possibility of applying the modified continuous tone model to characterize the tone reproduction of high addressibility printers. Both the continuous tone model and the modified halftone model will be compared for how well they characterize the tone reproduction characteristics of the printer.

Application Adaptive Bandwidth Management Using Real-Time Network Monitoring., Amit Grover

Electronic Theses and Dissertations

Application adaptive bandwidth management is a strategy for ensuring secure and reliable network operation in the presence of undesirable applications competing for a network’s crucial bandwidth, covert channels of communication via non-standard traffic on well-known ports, and coordinated Denial of Service attacks. The study undertaken here explored the classification, analysis and management of the network traffic on the basis of ports and protocols used, type of applications, traffic direction and flow rates on the East Tennessee State University’s campus-wide network. Bandwidth measurements over a nine-month period indicated bandwidth abuse of less than 0.0001% of total network bandwidth. The conclusion suggests …

Haptic-Geozui3d: Exploring The Use Of Haptics In Auv Path Planning, Rick Komerska, Colin Ware

Center for Coastal and Ocean Mapping

We have developed a desktop virtual reality system that we call Haptic-GeoZui3D, which brings together 3D user interaction and visualization to provide a compelling environment for AUV path planning. A key component in our system is the PHANTOM haptic device (SensAble Technologies, Inc.), which affords a sense of touch and force feedback – haptics – to provide cues and constraints to guide the user’s interaction. This paper describes our system, and how we use haptics to significantly augment our ability to lay out a vehicle path. We show how our system works well for quickly defining simple waypoint-towaypoint (e.g. transit) …

High-Frequency Volume And Boundary Acoustic Backscatter Fluctuations In Shallow Water, Timothy C. Gallaudet, Christian De Moustier

Center for Coastal and Ocean Mapping

Volume and boundary acoustic backscatter envelope fluctuations are characterized from data collected by the Toroidal Volume Search Sonar (TVSS), a 68 kHz cylindrical array capable of 360° multibeam imaging in the vertical plane perpendicular to its axis. The data are processed to form acoustic backscatter images of the seafloor, sea surface, and horizontal and vertical planes in the volume, which are used to attribute nonhomogeneous spatial distributions of zooplankton, fish, bubbles and bubble clouds, and multiple boundary interactions to the observed backscatter amplitude statistics. Three component Rayleigh mixture probability distribution functions (PDFs) provided the best fit to the empirical distribution …

Dowel-Concrete Contact Characteristics, Sri Vani Sirisha Motamarri

Graduate Theses, Dissertations, and Problem Reports (ETD)

In this thesis, the dowel-pulling force and the dowel-concrete coefficient of friction were measured using a novel laboratory setup of vibrating wire strain gauges embedded in both the dowel and concrete. The gages are set to measure the shrinkage strain induced in the concrete that surrounds the dowel as it cures causing the solidified concrete to clamp on the steel dowel. The measurements reveal that radial strain in concrete around the dowel is not uniform along the dowel circumference. As the dowel is pulled out of concrete, both the dowel-pulling force and the elastic strain recovery in concrete are recorded …
