Fly Ash As A Soil Amendment In The Northern Red River Valley, Amy Decker

Undergraduate Theses and Senior Projects

Combustion of coal occurs worldwide to produce energy for numerous residential and industrial processes. During coal combustion, byproducts including fly ash, bottom ash and slag are formed (Lafarge, 2004). By standard regulations, power plants in the United States and many other countries must effectively capture and dispose of these byproducts. Over 118 million tons of combustion byproducts are produced and captured each year in the United States alone. Disposal of this extraordinary amount of waste is difficult and costly. Finding ways to turn this waste into a resource has been necessary, and at times, profitable.

The past fifty years has …

Gain-Bandwidth Product Optimization Of Heterostructure Avalanche Photodiodes, Oh-Hyun Kwon, Majeed M. Hayat, Joe C. Campbell, Bahaa E.A. Saleh, Malvin Carl Teich

Electrical and Computer Engineering Faculty Research and Publications

A generalized history-dependent recurrence theory for the time-response analysis is derived for avalanche photodiodes with multilayer, heterojunction multiplication regions. The heterojunction multiplication region considered consists of two layers: a high-bandgap Al/sub 0.6/Ga/sub 0.4/As energy-buildup layer, which serves to heat up the primary electrons, and a GaAs layer, which serves as the primary avalanching layer. The model is used to optimize the gain-bandwidth product (GBP) by appropriate selection of the width of the energy-buildup layer for a given width of the avalanching layer. The enhanced GBP is a direct consequence of the heating of primary electrons in the energy-buildup layer, which …

Theoretical Investigation Of Quantum-Dot Avalanche Photodiodes For Mid-Infrared Applications, Sanjay Krishna, Oh-Hyun Kwon, Majeed M. Hayat

Electrical and Computer Engineering Faculty Research and Publications

A novel midinfrared sensor, called the quantum-dot avalanche photodiode (QDAP), is proposed which is expected to have improved signal-to-noise ratio (SNR) in the presence of Johnson noise over its quantum-dot (QD) counterpart. In the QDAP, an intersubband QD detector is coupled with a thin, low-noise GaAs avalanche layer through a tunnel barrier. The avalanche layer provides the necessary photocurrent gain required to overcome Johnson noise and nearly achieve the dark-current-limited SNR of the QD detector. In the proposed three-terminal device, the applied biases of the QD-detector and the avalanche-photodiode sections of the QDAP are controlled separately. This feature permits the …

A Study Of The Relationships Between End-User Information Systems Problems And Helpdesk Critical Success Factors In Higher Education, Richard Dale Parrott

CCAC Theses and Dissertations

In the last fifteen years, information technology (IT) customer support has increased in importance within higher education. The pervasiveness of computers and technology on the campus has allowed students, staff, and faculty to perform a multitude of tasks by controlling their own environments and setting their own priorities. Qualified professional system and user support services have lagged demand. The problem investigated in this study was end-users' satisfaction levels of the higher education helpdesk and how end-users' satisfaction levels affected a helpdesk manager's critical success factors performance and goals. In this study, the first goal was to identify the critical success …

M2mi Service Discovery Middleware Framework, Joel Donado

Theses

M2MI has been thought of as a paradigm for applications running on ad hoc networks of fixed and mobile wireless proximal devices. For this to function, so far, we have relied on the human configuration of the devices sharing the same application. This includes, setting up the M2MI layer through Java, and starting the M2MI application. M2MI has worked fine under this scheme. A more general approach is to join a network and automatically discover any services available, in the case we have the M2MI layer already started. Afterwards, we can choose the service that we want to use. For …

Elgamal-Type Signature Schemes In Modular Arithmetic And Galois Fields, Gerard Nealon

Theses

A digital signature is like a handwritten signature for a file, such that it ensures the identity of the person responsible for the file and prevents any unauthorized changes to the original file. Digital signatures use the same technology as most public key cryptosystems in which there is a public and private key. Most mathematical operations are done over a field Zp where p is some large prime. It is possible to do the same operations over other finite fields. My project explains and studies the different finite fields that can be used as well as ways to implement and …

Policy Options To Enhance Technology Diffusion: Modeling The Greenhouse Gas Reduction Potential Of Solid-State Lighting, Amanda Slocum

Theses

Solid-state lighting (SSL) is an emerging technology that is projected to provide substantial energy savings over conventional lighting sources by 2025. There is a growing concern over the consequences of climate change, largely attributed to anthropogenic emissions of carbon dioxide (CO2; a greenhouse gas) from fossil fuel combustion. Currently fossil-fuel combustion accounts for 70% of electricity produced in the U.S., and end-use lighting applications alone consume approximately one-fifth of this electricity. Therefore, replacing conventional lighting sources with energy-efficient SSL has the potential to significantly reduce electricity consumption which can in turn reduce CO2 emissions. However, previous research has shown there …

Computer-Supported Rehabilitation Management A Case Study Of Using Virtual Reality Technology In Ambulatory Training For Post-Acute Stroke Patients, Felix O. Akinladejo

CCAC Theses and Dissertations

This study investigated the use of virtual reality (VR) technology in ambulatory training for post-acute stroke patients, and sought to determine whether skills gained in virtual environments transfer to real-world conditions. Patients with stroke typically suffer dysfunctions that impair the complex set of motions involved in walking. The limited amount of therapy and resources offered by the current health care system does not provide the frequency and intensity of training needed for functional recovery of the walking skills in patients following stroke assaults. This study, therefore, developed and investigated an alternative intervention technique capable of providing the frequency and intensity …

The Wto, Export Subsidies, And Tax Competition, Reuven S. Avi-Yonah

Book Chapters

From its beginnings late in the 19th century, the modem state has been financed primarily by progressive income taxation. The income tax differs from other forms of taxation (such as consumption or social security taxes) in that in theory it includes income from capital in the tax base, even if it is saved and not consumed. Because the rich save more than the poor, a tax that includes income from capital in its base is more progressive (taxes the rich more heavily) than a tax that excludes income from capital (e.g., a consumption tax or a payroll tax). However, the …

A Child's Journey Through The Child Welfare System, Sue Badeau `, Sarah Gesiriech, Ann M. Haralambie, Amanda George Donnelly, Donald N. Duquette

Book Chapters

Once a child is known to the child welfare agency, the child and his or her family become subject to a series of decisions made by judges, caseworkers, legal representatives, and others, all of whom have an important role to play. A child may encounter dozens of other new adults, including foster parents, counselors, and doctors. Most children (60 percent) enter foster care when removed from their homes by a child protective agency because of abuse or neglect, or both. Others (17 percent) enter care because of the absence of their parents, resulting from illness, death, disability, or other problems. …

Representing Children And Youth, Donald N. Duquette, Marvin Ventrell

Book Chapters

Quality legal representation of all parties is essential to a high-functioning dependency court process. Quality legal representation of children in particular is essential in obtaining good outcomes for children. An adversarial court process that depends on competing independent advocacy to provide information will not produce good outcomes for litigants who lack competent advocates. Dependency court decisions are as good as the information on which the decisions are based. In order to promote the welfare of children in dependency court, therefore, children must be provided with competent independent legal representation.

Establishing Legal Permanence For The Child, Donald N. Duquette

Book Chapters

This chapter is intended to identify options for legal permanency that state law and the federal Adoption and Safe Families Act (ASFA) commonly recognize to better serve children in foster care. Ideally, the child will ultimately return safely to his or her home of origin. But when a return home is not possible, the child welfare legal process should result in a safe and legally secure alternative permanent placement for the child. The emphasis on legally secure permanent placement is meant to provide the child with psychological stability and a sense of belonging, and limit the likelihood of future disruption …

The Right Of States To Repatriate Former Refugees, James C. Hathaway

Articles

Armed conflict often results in the large-scale exodus of refugees into politically and economically fragile neighboring states. The burdens on asylum countries can be extreme, and may only be partly offset by the arrival of international aid and protection resources. Moreover, difficulties inherent in the provision of asylum have been exacerbated in recent years by the increasing disinclination of the wealthier countries that fund the United Nations High Commissioner for Refugees (UNHCR) and most other assistance agencies to meet the real costs of protection. In such circumstances, it is unsurprising that as conflicts wind down, host countries ordinarily seek to …

Procedural Incrementalism: A Model For International Bankruptcy, John A. E. Pottow

Articles

The headline-grabbing business failures of late have brought increased attention to the relatively unresolved area of multinational bankruptcies. Parmalat, Global Crossing, and United Airlines are among the few international juggernauts that have foundered. In the financial meltdowns of these cross-border institutions, assets and creditors are dispersed throughout commercial environments that rarely end neatly at national borders. There has been heated debate, both in scholarly literature and the practical battlefield, over how best to resolve these transnational insolvencies, and there is nothing yet approaching a consensus. Reform efforts of various stripes have almost uniformly failed to gain meaningful international support. At …

Confrontation After Crawford, Richard D. Friedman

Articles

The following edit excerpt, drawn from "The Confrontation Clause Re-Rooted and Transformed," 2003-04 Cato Supreme Court Review 439 (2004), by Law School Professor Richard D. Friedman, discusses the impact, effects, and questions generated by the U.S. Supreme Court's ruling in Crawford v. Washington last year that a defendant is entitled to confront and cross-examine any testimonial statement presented against him. In Crawford, the defendant, charged with attacking another man with a knife, contested the trial court's admission of a tape-recorded statement his wife made to police without giving him the opportunity to cross-examine. The tiral court admitted the statement, and …

Earl Warren: Law Enforcement Leads To Defendants' Rights, Yale Kamisar

Articles

Before becoming governor of California, Earl Warren spent 22 years in law enforcement: five as a deputy district attorney (1920- 25); thirteen as head of the Alameda County district attorney's office (1925-38); and four as state attorney general (1939-42). My thesis is that Warren's many years in law enforcement significantly affected his work as Chief Justice of the United States.

The Silver Lining: The International Tax Provisions Of The American Jobs Creation Act - A Reconsideration, Reuven S. Avi-Yonah

Articles

The American Jobs Creation Act of 2004, passed by the US Congress on 12 October and signed into law by President Bush on 22 October 2004, has been greeted by general dismay by various critics. The Act has been described as overloaded with “pork” and giveaways to special interest groups like tobacco farmers. The critics contend that the only achievement of the Act, the repeal of the “extraterritorial income” (ETI) regime that was ruled by the WTO to be a prohibited export subsidy, is dwarfed by 633 pages of special interest legislation. Even the Bush Administration distanced itself from the …

The Problem Of New Uses, Rebecca S. Eisenberg

Articles

Discovering new uses for drugs that are already on the market seems like it ought to be the low-lying fruit of biopharmaceutical research and development (R&D). Firms have already made significant investments in developing these drugs and bringing them to market, including testing them in clinical trials, shepherding them through the FDA regulatory approval process, building production facilities, and training sales staff to market them to physicians. By this point, the drugs have begun to enjoy goodwill among patients and physicians and casual observations in the course of clinical experience may point to potential new uses. One might expect that …

Evaluation Of Ecotourism In Armenia, Narine Yeghoyan

Theses

Over the last decades ecological tourism has become very popular all around the world. Ecotourism has emerged as a development tool, which aims to protect the natural area and cultural diversity by attracting the ecotourists and generating benefits for the local community without harming nature. Good interpretation services, cultural sensitivity and involvement with local community are three characteristics that differentiate ecotourism from other types of tourism. Ecotourism can bring many benefits, but if it is not organized properly, it can have very serious environmental consequences. Therefore evaluation of ecotourism product in a destination is important. It can help policy makers …

Damage Caps: Recent Trends In American Tort Law, Mark K. Osbeck

Articles

Damage caps and other limitations on damages have become increasingly important in American tort law during the past thirty years. This trend shows no signs of abating; in fact, it has gained increasing momentum since President Bush took office in 2001. This chapter traces the evolution of damage caps and other limitations on damages and provides a summary of recent developments in this area.

Regulation Of Companies With Publicly Listed Share Capital In The People's Republic Of China, Nicholas C. Howson

Articles

Mr. Chairman, colleagues, and friends: It is a great honor for me to be able to address this group of experts and legislators, and many colleagues and friends, on a topic I care deeply about-the regulation of so-called public companies, both outside of China and, since the early 1990s, inside of China. First, and with many of the others invited to participate in this conference today and tomorrow, I thank the Office of Legislative Affairs ("OLA") of the State Council of the People's Republic of China ("PRC") as well as the China Securities Regulatory Commission ("CSRC") for convening this very …
