Concrete Roughness Characterization Using Laser Profilometry For Fiber-Reinforced Polymer Sheet Application, Norbert H. Maerz, Poornima Chepur, John J. Myers, Justin Linz

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

The failure of a reinforced concrete member strengthened with fiberreinforced polymer (FRP) laminates may be caused by crushing of concrete, rupture of FRP laminates, or delamination of the FRP sheet. Therefore, the effectiveness and failure mode of FRP sheets applied to beams and columns is related to the degree of adhesion of the epoxy to the concrete surface. When a peeling or delamination failure can be avoided, a more effective engagement of the FRP sheet occurs, which results in more efficient use of the material. One of the principal factors affecting the bond behavior between the concrete and epoxy is …

The management of data in the mobile computing environment offers new challenging problems. Existing software needs to be upgraded to accommodate this environment. To do so, the critical parameters need to be understood and defined. We have surveyed some problems and existing solutions

A Case Study Of The Beneficial Reuse Of Treated Groundwater, Andrew Curtis Elmore, Thomas Graff

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

The future disposal of treated groundwater at the former Nebraska Ordnance Plant (NOP) Superfund site has been a topic of interest to the local property owners, the U.S. Army Corps of Engineers, and the local regulatory agencies. The Record of Decision for the site includes the extraction, treatment, and disposal of almost 3,000 gpm of groundwater with an estimated restoration time period exceeding 100 years. Interest from property owners and the Nebraska agency charged with regulating groundwater supply prompted the Corps of Engineers to consider several strategies for beneficially reusing the treated water. Alternatives included the establishment of a rural …

Design And Installation Of Horizontal Wick Drains For Landslide Stabilization, Paul Michael Santi, C. Dale Elifrits, J. A. Liljegren

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

One of the most effective options to stabilize landslides is to reduce the amount of water they contain by installing horizontal drains. A new type of horizontal drain material, geosynthetic wick drains, and a new installation method, driving drains rather than drilling them, were evaluated. Horizontal wick drains offer several advantages over conventional horizontal drains: They resist clogging, are inexpensive, may be deformed without rupture, and may be installed by unskilled laborers with a minimal investment in equipment. More than 100 drains were installed at eight sites in Missouri, Colorado, and Indiana using bulldozers, backhoes, and standard wick drain-driving cranes. …

Experiments On Adaptive Techniques For Host-Based Intrusion Detection, Timothy Draelos, Michael Collins, David Duggan, Edward Thomas, Donald C. Wunsch

Electrical and Computer Engineering Faculty Research & Creative Works

This research explores four experiments of adaptive host-based intrusion detection (ID) techniques in an attempt to develop systems that can detect novel exploits. The technique considered to have the most potential is adaptive critic designs (ACDs) because of their utilization of reinforcement learning, which allows learning exploits that are difficult to pinpoint in sensor data. Preliminary results of ID using an ACD, an Elman recurrent neural network, and a statistical anomaly detection technique demonstrate an ability to learn to distinguish between clean and exploit data. We used the Solaris Basic Security Module (BSM) as a data source and performed considerable …

Applying The Method Of Moments And The Partial Element Equivalent Circuit Modeling Techniques To A Special Challenge Problem Of A Pc Board With Long Wires Attached, Yun Ji, Bruce Archambeault, Todd H. Hubing

Electrical and Computer Engineering Faculty Research & Creative Works

This paper investigates a canonical printed circuit board (PCB) problem using both a method of moments (MoM) and a partial element equivalent circuit (PEEC) modeling technique. The problem consists of a PCB populated with three traces. One trace is a signal line and the other two are I/O lines that couple to the signal line and extend beyond the boundary of the board. Although the MoM code was a frequency domain code and the PEEC code was a time-domain code, good agreement was achieved in both the time-domain and the frequency-domain

Permeability Performance Of High-Performance Concrete Subjected To Various Curing Regimes, John J. Myers

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Concrete technology has continued to advance throughout the years to meet the demands of designers and innovative structural systems. Traditionally, the most common means to specify durable concrete has been via specifying a maximum water-to-cementitious material ratio or a minimum cement content. With the advent of high-performance concrete (HPC), which often has higher contents of cementitious materials and a variety of admixtures, questions about permeability performance and alternative methods to specify durable concrete have arisen. The study conducted herein comments on the applicability of prescriptive specifications for HPC and investigates the influence of curing regimes and concrete temperature development during …

The Status Of Dance Education Programs In Public Leisure Service And Non-Profit Youth Serving Organizations In The State Of Iowa, Ranae Elaine Keane-Bamsey

Graduate Research Papers

The purpose of this exploratory descriptive study was to investigate the status and scope of dance education programs offered by public leisure service organizations and non-profit youth agencies in the State of Iowa. In addition, the study was directed toward discerning the number of participants in existing dance programs provided by the aforementioned types of organizations. This research study was intended to provide a baseline of information to add to the general body of knowledge regarding the provision of dance education programs within the State of Iowa.

The Inventory of Iowa's Dance Programs, consisting of 31 questions, was distributed to …

A Comparison Of Health Curricula At Selected Rural Iowa Secondary Schools To A Recommended Model, Lowen Paul Anderson

Graduate Research Papers

The importance of educating the youth of today about healthy lifestyles cannot be overstated. In the United States the top four causes of death in 1998, each lifestyle-related, were (1) heart disease - 724,859 deaths, (2) cancer - 541,532, (3) stroke - 158,448, and (4) chronic obstructive pulmonary disease - 112,584, as reported by the Centers for Disease Control and Prevention (CDC, 2001 ). Fifteen years ago Kolbe (1986) identified the same top three leading causes of death and reported that they develop mainly from lifestyle habits.

The first encounter youth usually have with formal health education is in school. …

A Critical Linguistic Analysis Of A Popular Comic Genre In Japan, Angela Rawson

Theses: Doctorates and Masters

This research will focus on the issue of power and gender in the language of Japanese comics (manga). Comics in Japan are enormously popular and are read by a wide audience. They are aimed at specific audiences and it is my argument that the language of manga helps to reinforce certain social stereotypes - particularly the inferiority of women and the dominance of males. The language of children's manga will be analyzed using the framework of Critical Discourse Analysis (CDA), which concerns itself with the relation between ideology and power in discourse. The analysis will be at various levels including …

An Evaluation Of The Orientation Program For Newly Appointed Catholic Primary Principals, Samuel G. Fontaine

Theses: Doctorates and Masters

The structure and operation of Catholic schools in Western Australia have been in a process of change since the early 1970’s. Prior to 1971, most Catholic primary schools were administered by religious orders and much of the religious character of the school reflected the charisma of the particular religious order that operated the school. In the Year 2000 most Catholic primary schools former part of a state-wide system in which the Catholic Education Office (CEO) plays a major administrative and co-ordinating role.
