Crush Testing, Characterizing, And Modeling The Crashworthiness Of Composite Laminates, David M. Garner

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

Research in the field of crashworthiness of composite materials is presented. A new crush test method was produced to characterize the crush behavior of composite laminates. In addition, a model of the crush behavior and a method for rank ordering the energy absorption capability of various laminates were developed. The new crush test method was used for evaluating the crush behavior of flat carbon/epoxy composite specimens at quasi-static and dynamic rates. The University of Utah crush test fixture was designed to support the flat specimen against catastrophic buckling. A gap, where the specimen is unsupported, allowed unhindered crushing of the …

Checking Design Constraints At Run-Time Using Ocl And Aspectj, Yoonsik Cheon, Carmen Avila, Steve Roach, Cuauhtemoc Munoz

Departmental Technical Reports (CS)

Design decisions and constraints of a software system can be specified precisely using a formal notation such as the Object Constraint Language (OCL). However, they are not executable, and assuring the conformance of an implementation to its design is hard. The inability of expressing design constraints in an implementation and checking them at runtime invites, among others, the problem of design drift and corrosion. We propose runtime checks as a solution to mitigate this problem. The key idea of our approach is to translate design constraints written in a formal notation such as OCL into aspects that, when applied to …

Temperature Compensation Of Auxin Dependent Developmental Patterning, Nicholas J. Kaplinsky

Biology Faculty Works

The establishment of localized auxin gradients plays a central role in developmental patterning in plants. Auxin levels and responses have been shown to increase with temperature although developmental patterning is not affected. This suggests the existence of a homeostatic mechanism that ensures that patterning occurs normally over a range of temperatures. We recently described the cloning and characterization of BOBBER1 (BOB1), an Arabidopsis gene which encodes a small heat shock protein. BOB1 is required for the establishment of auxin gradients and for normal developmental patterning. BOB1 is also required for organismal thermotolerance and localizes to heat shock granules at elevated …

Fluorescent Protein Markers To Tag Collagenous Proteins: The Paradigm Of Procollagen Vii, Hye J. Chung, Andrzej Steplewski, Jouni Uitto, Andrzej Fertala

Department of Dermatology and Cutaneous Biology Faculty Papers

Fluorescent proteins are powerful markers allowing tracking expression, intracellular localization, and translocation of tagged proteins but their effects on the structure and assembly of complex extracellular matrix proteins has not been investigated. Here, we analyzed the utility of fluorescent proteins as markers for procollagen VII, a triple-helical protein critical for the integrity of dermal-epidermal junction. DNA constructs encoding a red fluorescent protein-tagged wild type mini-procollagen VII α chain and green fluorescent protein-tagged α chains harboring selected mutations were genetically engineered. These DNA constructs were co-expressed in HEK-293 cells and the assembly of heterogeneous triple-helical mini-procollagen VII molecules was analyzed. Immunoprecipitation …

Human Error In Mining: A Multivariable Analysis Of Mining Accidents/Incidents In Queensland, Australia And The United States Of America Using The Human Factors Analysis And Classification System Framework, Jessica Patterson

All Dissertations

Historically, mining has been viewed as an inherently high-risk industry. Nevertheless, the introduction of new technology and a heightened concern for safety has yielded marked reductions in accident and injury rates over the last several decades. In an effort to further reduce these rates, the human factors associated with incidents/accidents need to be addressed. A modified version of the Human Factors Classification and Analysis System (HFCAS-MI) was used to analyze lost time accidents and high-potential incidents from across Queensland, Australia and fatal accidents from the United States of America (USA) to identify human factor trends and system deficiencies within mining. …

Observations Of Very High Energy Gamma-Ray Emission From Supernova Remnants With Veritas, Mark Theiling

All Dissertations

The nature and source of cosmic rays has been at the core of particle astrophysics since their discovery almost a century ago. The cosmic ray spectrum is best described by a broken power law, and can be better understood as three distinct parts. Theory holds that cosmic rays up to ∼1015 eV – those below the “knee” or steepening in the spectrum – are produced in the shocks of supernova remnants. Direct detection of cosmic rays produced in supernova remnant shocks is impossible, however, as cosmic rays below ∼1018 eV are deflected by the Galactic magnetic field and cannot be …

Job Offer Expectancies: An Analysis Of Antecedents, Outcomes And Moderated Effects, Matthew Millard

All Dissertations

Restricted by limited time and resources, job applicants are often required to make decisions based on their own estimations of an organization's likelihood to extend a job offer. These estimations, or offer expectancies, may be linked to several applicant attitudes and behaviors that have yet to be examined fully in the literature (e.g., job pursuit or information seeking behaviors, search expansion, etc.). We know relatively little about how these perceptions are formed. In this study, actual job applicants were asked to report their perceptions of and behavioral intentions towards organizations that they are currently applying to but have not yet …

A Cognitive Model For Problem Solving In Computer Science, Jennifer Parham

All Dissertations

According to industry representatives, computer science education needs to emphasize the processes involved in solving computing problems rather than their solutions. Most of the current assessment tools used by universities and computer science departments analyze student answers to problems rather than investigating the processes involved in solving them. Approaching assessment from this perspective would reveal potential errors leading to incorrect solutions.
This dissertation proposes a model describing how people solve computational problems by storing, retrieving, and manipulating information and knowledge. It describes how metacognition interacts with schemata representing conceptual and procedural knowledge, as well as with the external sources of …

Production And Characterization Of Novel Shaped Fibers For Fluid Sorption And Transport, Lisa Fuller

All Dissertations

This work investigated the production and characterization of novel shaped fibers for fluid adsorption and transport. Shaped fibers such as Y, H, and octolobal, as well as conventional round fibers, were extruded using a research melt extruder. The fibers were extruded from 18 melt flow index (MFI) polypropylene (PP) and blends of 18 MFI PP and 400 MFI PP. Hydrophilic spin finish Bozzetto Favorol SF2 was applied to the surface of extruded fibers and hydrophilic polyester additive LB-100 was included in the blend of some H fibers to increase the hydrophilicity of the fiber surface. The geometric shape retention of …

An Investigation On The Use And Flexibility Of Genetic Algorithms For Logistic Regression, Sara Yoder

All Dissertations

Social scientists and other users of large data sets often desire a model to predict the probability that some condition exists, such as the probability that a person has diabetes or that a credit card transaction will be fraudulent. In general, this can be done by data mining techniques, which allow multiple records of data composed of numerous independent variables and one dependent variable to be examined in a statistical fashion to make a predictive model. One particular technique used is logistic regression. Logistic regression forms a predictive model based on a set of independent variables by assigning coefficients to …

An Evaluation Of Potential Technologies For A Web Based Development Environment For Cs1 Students, Manuel Garcia

Computer Science and Software Engineering

The goal of this senior project was to design a web-based integrated development environment that would incorporate Web-CAT. Web-CAT is an automated testing tool designed by Stephen Edwards at Virginia Tech University, to help beginning students learn test-driven development. This tool runs on a server where a professor assigns usernames and passwords to students so they can submit code. This program can assist professors in grading, and students in showing errors in code. The development environment design waskept simple to create less confusion for beginning programming students. This development environment will be online to give all students universal access and …

Session Initiation Protocol Server Implementation For Linksys Routers, Matthew Duder

Computer Science and Software Engineering

Session Initiation Protocol (SIP) is a signaling protocol used for network-based media interaction. SIP Servers are required to process and forward requests and responses between end clients. Once connection setup is complete, the end clients utilize some other protocol (such as Real-Time Transport Protocol) to complete their task.

Such a server may be implemented and installed on routers. Unlike the SIP protocol, however, router development currently remains without standards. For this project, Linux-based residential-grade routers had their kernels replaced with an open source version. This allowed for installation of open-source development, such as a SIP server implementation.

This project led …

Redesigning Src2pkg, A Linux Package Creation Toolkit, Timothy Goya

Computer Science and Software Engineering

Package managers ease installation and removal of applications. However, as the name indicates, in order for a package manager to be useful, they need packages created from upstream sources to manage. This is the purpose of src2pkg, a toolkit written in Bash shell script which automates many package creation tasks. src2pkg, however, suffers from major design flaws that cripple its ability to package some exotic upstream sources. src2pkg-ng is a prototype redesign of src2pkg that eliminates these flaws. src2pkg-ng fully supports creating packages for Slackware and Slackware-compatible variants for at least 21 upstream sources with various levels of complexity. Debian …

Deadly Dilemmas Ii: Bail And Crime, Larry Laudan, Ronald J. Allen

Chicago-Kent Law Review

This is another in a series of papers examining the interaction between the implications of the deadly dilemma of governing that virtually all governmental action involves unavoidable conflict between equally laudatory goals and the conventional way of thinking about social errors. Typically the pursuit of any particular goal has as its consequence precisely the kind of harm that is desired to be avoided. For example, serious felons are sent to prison in part to protect innocent parties from their future predations, but those same felons often prey upon fellow prisoners, including murder. Moreover, felonies committed in prison only begin the …

The Roberts Court's Failed Innocence Project, Janet C. Hoeffel

Chicago-Kent Law Review

In this article, Professor Hoeffel discusses the Roberts Court's obvious struggle with its actual innocence jurisprudence. It is a struggle that was only theoretical in the days before DNA exonerations. While the Court had two opportunities to clarify the role of wrongful convictions in the criminal justice system, it has declined to do so. In House v. Bell, the Court ratcheted up the standard of proof for freestanding constitutional claims of innocence to a level no petitioner could understand, much less meet. Then, in District Attorney's Office for the Third Judicial District v. Osborne, the Court held that …

Taking Reasonable Doubt Seriously, Arnold H. Lowey

Chicago-Kent Law Review

In recent years, we have discovered a spate of factually innocent people who have been convicted. In this article, Professor Loewy contends that the failure of juries to take reasonable doubt seriously contributes to this phenomenon. Professor Loewy via an illustrative fictitious case explains that juries might be reluctant to give the defendant the benefit of a reasonable doubt because of their concern about putting dangerous criminals back on the street. He then asks whether we really want juries to take reasonable doubt seriously. Concluding that we do, he examines how we can do that. Loewy concludes that the best …

Second Thoughts On Damages For Wrongful Convictions, Lawrence Rosenthal

Chicago-Kent Law Review

After the DNA-inspired wave of exonerations of recent years, there has been widespread support for expanding the damages remedies available to those who have been wrongfully accused or convicted. In this article, Professor Rosenthal argues that the case for providing such compensation is deeply problematic, whether advanced in terms of no-fault or fault-based liability. Although a regime of strict liability is sometimes thought justifiable as a means of creating an economic incentive to scale back such liability-producing conduct to optimal levels, this rationale has little application to the criminal justice system. Instead, a regime of strict liability would operate as …

Intentional Wrongful Conviction Of Children, Victor Streib

Chicago-Kent Law Review

Intentional wrongful convictions in cases involving child offenders may occur when judges have insufficient evidence proving any crime by the child but feel a strong need for the courts to intervene in the child's life and behavior. They believe that the negative factors attached to such a status are worth suffering if the child gains entry into a desired state program. This is wrongfully convicting the child "for the child's own good." Juvenile court judges too often receive knowledge of the child's background and previous record prior to any trial or hearing in order to devise the best result for …
