Industry In Harper's Ferry, West Virginia, 1861-1865., Coral L. N. Totten

Graduate Theses, Dissertations, and Problem Reports (ETD)

Harperís Ferry, West Virginia began its existence as a small settlement in the Northern Neck of colonial Virginia. Originally it was a point of departure for westward expansion, but due to its geographical location, the cultural background of the immigrants who settled there, and technological advancements in transportation, communication and manufacturing, it became a model of industrial development in the nineteenth century. Although it possessed all the factors necessary for continued growth, unwise land management practices, due in part to the Civil War, as well as the consequences of war itself, and technological advancements in steam power, led to the …

Fragm: A Blasting Fragmentation Model Of Rocks., Sergey Victorovych Zagreba

Graduate Theses, Dissertations, and Problem Reports (ETD)

Fragmentation is a major concern of any blasting operation. Information on the degree and size distribution of fragments within a blasted rock mass is essential for efficient rock loading and crushing operations. Detailed literature review shows that majority of the previous researchers estimated blast fragmentation by considering four basic variables, i.e. rock properties, explosive properties, drilling pattern and bench geometry. However, when considering the effect of burden on rock fragmentation, simplified assumptions were made and its variability along the bench height was often ignored. In reality, because of the non-uniform burden along the bench height, the actual powder factor in …

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 …

Spsm And Spc For Software Process And Project Management, Omar F. El-Gayar

Research & Publications

Software process simulation modeling (SPSM) provides a platform for process and project management. On the other hand, statistical process control (SPC) provides the means to assess a process for stability and capability through visualization. This paper provides a framework for integrating SPSM and SPC. The framework realizes their synergy by leveraging the investment in supporting software measurement processes, ensuring the stability of the underlying development process, and enhancing simulation output using visualization techniques made possible through SPC. The paper illustrates the framework by integrating SPC to an existing SPSM. The integrated model is then used to evaluate the underlying process …

How Should We Theorize Class Interests In Thinking About Professional Regulation: The Early Naacp As A Case Example, Susan Carle

Scholarly Articles in Law Reviews & Journals

INTRODUCTION The Editors of the Cornell Journal of Law and Public Policy have specifically requested that I address in this essay some research I finished quite a while ago, but to which I hope to return in the near future, concerning the history of the first national legal committee of the National Association for the Advancement of Colored People (NAACP). (1) Therefore, I plan to raise a big picture question left unanswered by that earlier research here: how should we understand lawyers' class interests in relation to their involvement in the development of legal ethics rules concerning public interest law …

Study Of A Growth Instability Of Γ-In[Sub 2]Se[Sub 3], C. Amory, J. C. Bernede, S. Marsillac

Electrical & Computer Engineering Faculty Publications

γ-In[sub 2]Se[sub 3] thin film are deposited for various substrate temperatures in the range of 523–673 K. This study shows that at 573 and 673 K the thin films are well crystallized with grains aligned along the c axis. Between these temperatures, a domain of instability appears where the γ-In[sub 2]Se[sub 3] thin films have a randomly orientation and the c-lattice parameter increases. The presence of the metastable phase κ-In[sub 2]Se[sub 3], during the growth, can explain the existence of this domain of instability. The insertion of Zn during the preparation process allows us to stabilize the phase κ at …

Compact Supercell Method Based On Opposite Parity For Bragg Fibers, Wang Zhi, Ren Guobin, Lou Shuquin, Liang Weijun, Shangping Guo

Electrical & Computer Engineering Faculty Publications

The supercell- based orthonormal basis method is proposed to investigate the modal properties of the Bragg fibers. A square lattice is constructed by the whole Bragg fiber which is considered a supercell, and the periodical dielectric structure of the square lattice is decomposed using periodic functions (cosine). The modal electric field is expanded as the sum of the orthonormal set of Hermite-Gaussian basis functions based on the opposite parity of the transverse electric field. The propagation characteristics of Bragg fibers can be obtained after recasting the wave equation into an eigenvalue system. This method is implemented with very high efficiency …

Numerical Techniques For Excitation And Analysis Of Defect Modes In Photonic Crystals, Shangping Guo, Sacharia Albin

Electrical & Computer Engineering Faculty Publications

Two numerical techniques for analysis of defect modes in photonic crystals are presented. Based on the finite-difference time-domain method (FDTD), we use plane wave incidences and point sources for excitation and analysis. Using a total-field/scattered-field scheme, an ideal plane wave incident at different angles is implemented; defect modes are selectively excited and mode symmetries are probed. All modes can be excited by an incident plane wave along a non-symmetric direction of the crystal. Degenerate modes can also be differentiated using this method. A proper arrangement of point sources with positive and negative amplitudes in the cavity flexibly excites any chosen …

Simple Plane Wave Implementation For Photonic Crystal Calculations, Shangping Guo, Sacharia Albin

Electrical & Computer Engineering Faculty Publications

A simple implementation of plane wave method is presented for modeling photonic crystals with arbitrary shaped ‘atoms’. The Fourier transform for a single ‘atom’ is first calculated either by analytical Fourier transform or numerical FFT, then the shift property is used to obtain the Fourier transform for any arbitrary supercell consisting of a finite number of ‘atoms’. To ensure accurate results, generally, two iterating processes including the plane wave iteration and grid resolution iteration must converge. Analysis shows that using analytical Fourier transform when available can improve accuracy and avoid the grid resolution iteration. It converges to the accurate results …

A Preliminary Study Of Sustainable Eco-Industrial Partnerships In The State Of Iowa, Kathleen L. Hennings

Dissertations and Theses @ UNI

The proliferation of industry around the globe, coupled with concerns about the dwindling supply of raw materials, has fostered the emergence of a new manufacturing ideology. In contrast to the linear manufacturing model, raw material in and finished product out, precision manufacturing takes waste material in and provides a new product out. Companies in this study who participated in precision manufacturing were identified as partners when one company sold or traded a waste product to a separate company who used the waste in their primary production. This study was initiated to determine the factors present in successful waste exchange partnerships …

First Measurement Of Transferred Polarization In The Exclusive →E P → E'K+ →Λ, M. Bektasoglu, K. V. Dharmawardane, G. E. Dodge, T. A. Forest, C. E. Hyde-Wright, A. V. Klimenko, S. E. Kuhn, R. A. Niyazov, L. M. Qin, L. B. Weinstein, J. Yun

Physics Faculty Publications

The first measurements of the transferred polarization for the exclusive ^→ep → e'K+ ^→Λ over right arrow reaction have been performed at Jefferson Laboratory using the CLAS spectrometer. A 2.567 GeV beam was used to measure the hyperon polarization over Q² from 0.3 to 1.5 (GeV/c)², W from 1.6 to 2.15 GeV, and over the full K⁺ center-of-mass angular range. Comparison with predictions of hadrodynamic models indicates strong sensitivity to the underlying resonance contributions. A nonrelativistic quark-model interpretation of our data suggests that the s ^-s quark pair is produced with spins predominantly …

Criminal Defenders And Community Justice: The Drug Court Example, William H. Simon

Faculty Scholarship

The Community Justice idea and its core institution – the Community Court – is an ambitious innovation intended to generate new solutions and practices. It thus inevitably calls for adaptation of the established roles associated with the court system, and especially the criminal justice system. It asks practitioners to learn new skills, to accept new conventions, and to participate in the elaboration of a rapidly evolving experiment.

It is thus not surprising that many lawyers are anxious about the system. It remains an interesting question, however, whether their anxiety represents something more than the discomfort that change and challenge typically …

Novel Concepts For Monitoring The Stability Of Open Pit Mine Highwalls Using Radar Interferometry And Spectral Imaging, Jami Girard Dwyer

Masters Theses

"Ground control problems at surface mining operations can occur for a variety of reasons. The geologic setting, rock strengths, joint spacing, orientation, pore pressures, and many other factors contribute to slope instabilities that range from small rock falls to massive slides of material. While much of this ground movement can be predicted or controlled, each year many completely unexpected failures occur. This poses serious safety and economic issues for the mining industry, since any unanticipated movement of the ground increases the potential for significant property damage, injuries, and even death. In the United States alone, 70 people died in slope …

What Happened To The Skeptical Environmentalist, David Schoenbrod, Christi Wilson

Articles & Chapters

This essay focuses on the critical reaction to Bjorn Lomborg's book, The Skeptical Environmentalist. After the book was glowingly reviewed in the Washington Post, the Economist, and other influential publications, it was critically reviewed in Scientific American, Nature, and Science and criticized by environmental organizations. The criticism went beyond trying to show him wrong on environmental policy to claim that he should be disqualified as a participant in debates on environmental policy. The basis for the disqualification was that he does not understand the science or was disingenuous in his treatment of it. In analyzing this effort to disqualify him, …

Legal Services In The Doha Round, Sydney M. Cone Iii.

Articles & Chapters

As a subcategory of professional services and a sub-subcategory of business services, legal services, when supplied transnationally, are the subject of negotiation in the current round of multilateral trade negotiation known as the Doha Round. The negotiations on legal services that take place in the Doha Round have considerable potential for affecting the economics and activities of lawyers and law firms, and for influencing the content of local professional rules governing the practice of law. This article examines that potential.

The Shape Of The Universe: The Impact Of Unpublished Opinions On The Process Of Legal Research, William R. Mills

Articles & Chapters

Unpublished appellate judicial opinions present formidable challenges for modern legal researchers, from both practical and ethical points of view. The practice of selective publication of court opinions, and attendant court rules that restrict citation of unpublished opinions, have long been the subject of debate within legal profession. The recent case of Anastasoff v. United States, 223 F.3d 898 (8th Cir. 2000), vacated as moot 235 F.3d 1054 (8th Cir. 2000), has rekindled this debate, giving it a new constitutional dimension, and placing it squarely within the context of judicial accountability and the appropriate separation of powers among our branches 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 …
