Logistic Curves, Extraction Costs And Peak Oil, Robert J. Brecha

Physics Faculty Publications

Debates about the possibility of a near-term maximum in world oil production have become increasingly prominent over the past decade, with the focus often being on the quantification of geologically available and technologically recoverable amounts of oil in the ground. Economically, the important parameter is not a physical limit to resources in the ground, but whether market price signals and costs of extraction will indicate the efficiency of extracting conventional or nonconventional resources as opposed to making substitutions over time for other fuels and technologies. We present a hybrid approach to the peak-oil question with two models in which the …

The Unstructured Grid Incompressible Navier-Stokes Algorithm For Convective Heat Transfer Based On Artificial Compressibility, Jessica Elaine Kress

Masters Theses and Doctoral Dissertations

The development of an explicit unstructured grid finite-volume scheme for solving the full incompressible Navier-Stokes equations along with the energy equation in a strongly coupled manner is presented. The Boussinesq approximation is utilized to account for thermal buoyancy. The method of artificial compressibilty is used to solve the resulting equations in a time marching fashion. Roe's approximate Riemann solver is used for the construction of the numerical flux. An eigensystem is derived for the flux Jacobian matrix, which is used in the evaluation of the numerical flux and the characteristic variable boundary conditions. The resulting algorithm is validated by simulating …

Activity Of The Beta-Cyanoalanine Synthase Pathway Is Associated With The Response To Abiotic Stress By Arabidopsis Thaliana., Marylou Machingura

Dissertations

Cyanide is produced throughout a plant's life cycle alongside the hormone ethylene by oxidation of 1-aminocyclopropane-1-carboxylic acid. Production increases during certain developmental stages such as seed germination, seedling elongation, fruit ripening and senescence. Abiotic stresses increase ethylene production giving rise to `stress cyanide'. Cyanide also comes from metabolism of cyanogenic compounds. Cyanide is however, a toxic chemical which readily binds to metallo-enzymes inhibiting primary metabolic processes. Plants have mechanisms to maintain cyanide homeostasis such as the β-cyanoalanine pathway whereby cysteine reacts with cyanide forming β--cyanoalanine, mediated by β-cyanoalanine synthase and cysteine synthase. A dual nitrilase 4 enzyme then converts the …

Synergy And Its Limits In Managing Information Technology Professionals, Thomas W. Ferratt, Jayesh Prasad, Harvey Enns

MIS/OM/DS Faculty Publications

We examine the effects of human resource management (HRM) practices (e.g., career development, social support, compensation, and security) on IT professionals‟ job search behavior. Job search is a relatively novel dependent variable in studies of voluntary withdrawal behavior, in general, and for IT professionals, in particular. From a universalistic perspective, HRM practices individually and in combination exhibit independently additive effects on job search behavior. Our study contrasts this perspective with configurational theory, hypothesizing that proposed idealtype configurations of HRM practices have synergistic effects on job search behavior. We contribute to the IT and broader HRM literature by theoretically explicating and …

The Effect Of Pause Duration On Intelligibility Of Non-Native Spontaneous Oral Discourse, Ryan Frederick Lege

Theses and Dissertations

Pausing is a natural part of human speech. Pausing is used to segment speech, negotiate meaning, and allow for breathing. In oral speech, pausing, along with other suprasegmental features, plays a critical role in creating meaning as comprehensible speech is seen as a goal for language learners around the world. In order to be comprehensible, language learners need to learn to pause correctly in their speaking. Though this notion is widely accepted by applied linguists and many language teachers, the effect of pausing on intelligibility of spontaneous oral discourse has not been established by empirical data. This study isolates pause …

When Pages Collide: Dissecting The Words Of Mormon, Jack M. Lyon, Kent R. Minson

BYU Studies

Careful readers of the Book of Mormon have probably found verses 12-18 of the Words of Mormon to be a bit of a puzzle. For stylistic and other reasons, they do not really fit with verses 1-11, so commentators have tried to explain their presence as a sort of "bridge" or "transition" that Mormon wrote to connect the record of the small plates with his abridgment from the large plates. This paper proposes a different explanation: Rather than being a bridge into the book of Mosiah, these verses were originally part of the book of Mosiah and should be included …

Asynchronous Ultrasonic Trilateration For Indoor Positioning Of Mobile Phones, Viacheslav Filonenko (Thesis)

Theses

Spatial awareness is fast becoming the key feature on today‟s mobile devices. While accurate outdoor navigation has been widely available for some time through Global Positioning Systems (GPS), accurate indoor positioning is still largely an unsolved problem. One major reason for this is that GPS and other Global Navigation Satellite Systems (GNSS) systems offer accuracy of a scale far different to that required for effective indoor navigation. Indoor positioning is also hindered by poor GPS signal quality, a major issue when developing dedicated indoor locationing systems. In addition, many indoor systems use specialized hardware to calculate accurate device position, as …

Seepage And Stability Of A Dam In An Artesian Setting, Sean A. Parks

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Willow Creek Dam is located in a unique region on the boundary of a confined aquifer, where artesian conditions exist. Recently, groundwater levels have exceeded the elevation of the downstream berm well above anticipated piezometric elevations. It was presumed from limited evidence that these high piezometric levels resulted from pressure in the aquifer rather than from seepage out of the reservoir. The purpose of this investigation was to determine the relative contributions of the reservoir and the regional groundwater to observed piezometric levels and how these levels affect seepage exit gradients and slope stability of the dam.

Modeling Of Yeast Pheromone Pathway Using Petri Nets, Abhishek Majumdar

School of Computing: Dissertations, Theses, and Student Research

Yeast (Saccharomyces cerevisiae) is one of the most widely studied single celled organisms. Mating of yeast cells occur between cells of opposite mating types a and alpha. Pheromone secretion by a cell alerts the corresponding opposite type cell about its presence and eventually facilitates the process of mating between them. The details of how pheromones affect cells can be studied from the pheromone response pathway in a yeast cell. A response pathway typically depicts the chain of interactions that happens between the different proteins in the cells in response to the pheromone. In this thesis we model the …

Identification Of Tcp Protocols, Juan Shao

School of Computing: Dissertations, Theses, and Student Research

Recently, many new TCP algorithms, such as BIC, CUBIC, and CTCP, have been deployed in the Internet. Investigating the deployment statistics of these TCP algorithms is meaningful to study the performance and stability of the Internet. Currently, there is a tool named Congestion Avoidance Algorithm Identification (CAAI) for identifying the TCP algorithm of a web server and then for investigating the TCP deployment statistics. However, CAAI using a simple k-NN algorithm can not achieve a high identification accuracy. In this thesis, we comprehensively study the identification accuracy of five popular machine learning models. We find that the random forest model …

Dynamic Data Race Detection And Healing, Du Li

School of Computing: Dissertations, Theses, and Student Research

Perpetual availability is an important operational goal in today's computer systems. However, achieving this goal is challenging because modern software systems contain faults that can cause them to fail. For example, multi-threading is widely used in modern software to fully utilize the computing capability of multicore processors. However, employing multi-threading can lead to concurrency faults such as deadlock and data race that are notoriously difficult to to isolate, detect, and repair.Data races, which involves two concurrent accesses to the same data where at least one is a write, are the most common concurrency faults.

As our first step, we investigate …

Do Credit-Based Transfer Programs Have An Impact On Intellectual Development From Secondary Education To Post-Secondary Education?, James Uhlenkamp

Department of Educational Administration: Dissertations, Theses, and Student Research

This descriptive, retrospective quantitative study identified the influence that credit-based transfer programs have on the intellectual development positions of college matriculates at a private, residential, church-affiliated master’s degree granting university in the Midwest. This determination presents a better success measure for credit-based transfer programs than the measures used in previous studies: academic momentum, persistence rate, college grade point average, and degree attainment. People transitioning through intellectual development positions gain critical thinking skills and adopt more of the habits of mind and of working that characterize a well-educated person.

Thermalization And Initial State-Recurrence In Discrete Kdv-Like Lattices, Garrett Taylor Nieddu

Theses, Dissertations and Culminating Projects

Three discretizations of the Korteweg de-Vries equation are studied; convergence rate, initial state-recurrence, and the energy distribution of the three schemes are all considered. For each discrete scheme over 300 lattices with varying grid sizes were investigated, and the solutions were compared with other lattices from the same scheme, as well as solutions from the other two. It is found that the two schemes that are least accurate display the best recurrence at intermediate grid sizes, away from convergence. This is a notable result because the best recurrence is expected to be found in the most accurate, and converged lattices. …

Monitored Disclosure: A Way To Avoid Legislative Supremacy In Redistricting Litigation, Mark Tyson

Washington Law Review

The Speech or Debate Clause of the U.S. Constitution protects members of Congress from testifying about “legislative acts” or having “legislative acts” used against them as evidence. U.S. Supreme Court decisions delineating the scope of what constitutes a “legislative act” have an episodic feel and have failed to create a readily applicable test for new factual scenarios. One such scenario occurs when members of Congress communicate with state legislators regarding congressional redistricting. Courts must know how to handle instances where members of Congress assert legislative privilege in the redistricting context, and specifically when members of Congress assert the privilege in …

Perceptions Of Mental Illness In The Legal System, Krista Wallace

Criminal Justice

Previous research suggests that there are stereotypes and misperceptions about the mentally ill population which affect juror’s decision making in cases where the insanity defense is raised. Many individuals believe it to be a “loophole” in the criminal justice system for offenders to escape punishment (Skeem and Golding, 2002). This study explores community perceptions of schizophrenia and personality disorders in a legal context. Results support that individuals are significantly less confident of their verdict decisions when the offender has a mental illness than when the offender has no mental illness. In addition, the presence of a mental illness significantly affects …

Imagining What Eve Would Have Said After Cain’S Murder Of Abel: Rhetorical Practice And Biblical Interpretation In An Early Byzantine Homily, Kevin Kalish

Bridgewater Review

Why does the story of Cain and Abel leave out what we would consider essential details? Is there a reason for this silence? Works of fiction that imagine a historical event from an untold perspective are as popular as ever, and recent years have seen an influx of fiction that gives voice to silent characters in older works of fiction. By imagining what other characters might have said, we also come to a deeper understanding of the text.

Evidence-Based Policy For Asymptomatic Bacteriuria In The Institutionalized Elderly, Anna Rachel Olson

Doctoral Scholarly Projects & Capstones

The practice of mistaking asymptomatic bacteriuria (ASB) for urinary tract infections (UTI) is widespread in nursing homes and is contributing to patient overtreatment and adverse side effects such as clostridium difficile and multi-drug resistant microorganisms. The purpose of this DNP capstone project was to (a) write evidence-based policy and procedures (P&Ps) for evaluating institutionalized elders with clinical status changes when UTI was suspected, (b) utilize nursing leadership teams (NLT) in four northern Colorado nursing homes to implement evidence-based practice (EBP), and (c) evaluate implementation methods for their success in changing practice.
