A Schooling On Their Implications For Software Engineering [Trends], Ann K. Miller

Electrical and Computer Engineering Faculty Research & Creative Works

A discussion is presented on trends in software engineering. This can be done by simply extrapolating some of the popular, current trends. And, in fact, we examine a few of these obvious indicators. However, software engineering has had new approaches that are more revolutionary than evolutionary. In particular, we try to discern trends in software engineering based on trends in delivered software systems.

Parasitoids Of The Bean Leaf Beetle (Coleoptera: Chrysomelidae) Found In Nebraska Soybean Fields, Stephen D. Danielson, James R. Brandle, Laurie Hodges

Department of Agronomy and Horticulture: Faculty Publications

The bean leaf beetle, Cerotoma trifurcata (Forster) (Coleoptera: Chrysomelidae), is the major insect pest of soybean in Nebraska and throughout much of the midwestern United States. Natural enemies of the bean leaf beetle have been reported in other states, but none have been reported in Nebraska. In this study, bean leaf beetle adults were obtained by aspirating those found on soybean plants early in the season and by sweep net once plants were in the V4 stage (approximately 0.33 meter tall). Sampling was done in 1997 and 1998 in soybean fields at the University of Nebraska Agricultural Research and Development …

Awareness Of Hazard Analysis Critical Control Points, Gayle Brosseau

Theses

This study was an attempt to identify the awareness of principles of Hazard Analysis Critical Control Point (HACCP) by individuals who completed an eight-hour food handlers' class at Los Angeles Mission College. A six-item questionnaire was distributed to one hundred eighty individuals enrolled in the food handlers' classes during the winter of 1999-2000. One hundred twenty-five questionnaires were returned and tabulated during the spring 2000. Data analysis revealed that there is limited awareness of HACCP principles by trainees. The study, coupled with the literature review, indicates that there is a need for HACCP training. Other research showed a correlation between …

The Evolution Of Internet Interconnections, Sean Butler

Theses

In 1995, the NSF officially shut down the NSFNet backbone, thereby ending the nascent Internets early architecture as a single backbone network. Today, the Internet is a group of loosely interconnected networks run by many diverse companies. These interconnections are in no way controlled by any industry or government agency, and are therefore held together only by the market demands of the Internet community. Although the FCC has traditionally maintained a stance of "unregulation" of all information and computer networks, they have increasingly show interest in ensuring the rapid deployment of Internet access. In addition, as more and more critical …

The Causes And Effects Of Job Dissatisfacation Among Emergency Room Nurses, Karen Shuptar

Theses

Statistics point to the fact that there is a nursing shortage. The number of people entering the field of nursing is declining and the number of nurses leaving the field is increasing. According to past studies, one of the reasons nurses are leaving the field is due to job dissatisfaction. This paper focuses on emergency room nurses at Strong Memorial Hospital, in Rochester, New York. The causes of their job dissatisfaction are studied as well as the effect their dissatisfaction has on their nursing careers. The results of this study indicate that emergency department nurses at Strong do not want …

Ethylene Production, Cluster Root Formation, And Localization Of Iron(Iii) Reducing Capacity In Fe Deficient Squash Roots, Brian M. Waters, Dale G. Blevins

Department of Agronomy and Horticulture: Faculty Publications

Dicots and non-graminaceous monocots have the ability to increase root iron(III) reducing capacity in response to iron (Fe) deficiency stress. In squash (Cucurbita pepo L.) seedlings, Fe(III) reducing capacity was quantified during early vegetative growth. When plants were grown in Fe-free solution, the Fe(III) reducing capacity was greatly elevated, reached peak activity on day 4, then declined through day 6. Root ethylene production exhibited a temporal pattern that closely matched that of Fe(III) reducing capacity through day 6. On the 7th day of Fe deficiency, cluster root morphology developed, which coincided with a sharp increase in the root Fe(III) …

Illusory Coerrelations In School Psychologists' Diagnoses Of Learning Disabilities, Marc Renzoni

Theses

Illusory correlation is the perception of an association between two uncorrected variables such as intersubtest scatter on the Wechsler Intelligence Scale for Children - Third Edition (WISC-III) and the presence of a learning disability. This study assessed the extent to which school psychologists are influenced by this illusory correlation. Three independent variables were varied systematically. One variable was relevant to the diagnosis of a learning disability (a discrepancy between expected and actual levels of achievement on the Wechsler Individual Achievement Test (WIAT)). Another was irrelevant to the diagnosis (intersubtest scatter on the WISC-III). The third independent variable was used as …

Design Of A Wristwatch Pda, Kun-Chi Wu

Theses

This thesis concerns the design of a Wrist Device for assisting a person in one's daily tasks. Wouldn't it be nice if we could fit all the communication and data management tools we ever needed on our wrist? I personally like the idea. It is not because I am a watch collector that I chose to design a wrist style PDA.1 I think to put a PDA on your wrist is not only a very cool idea, but also the best way of carrying a really personal device with you. Since we are already used to putting a watch on …

Factors That Generate Effective Teams, Alberto V. Lenz Cesar

Theses

The journey to prosper competitively in the millennium will demand teamwork. The use of a team-based structure in organizations is no longer just a surplus tool to enhance service quality in the operation. In today's developed economies, the use of effective teams has proven to be essential for helping businesses to have continued prosperity and success on a long-term basis. Further, building teams has shown means for organizations to differentiate from competition, once copying human capabilities is not easy as copying technologies advancements. Therefore, in an environment of constant change, organizations must have perseverance and courage to stay on course …

Crop Quality And Utilization: A Twelve-Hour In Vitro Procedure For Sorghum Grain Feed Quality Assessment, Jeffrey F. Pedersen, Todd Milton, R. A. Mass

Department of Agronomy and Horticulture: Faculty Publications

Improvedmethods for assessing cereal crop feed value are a prerequisite for the genetic improvement of sorghum [Sorghum bicolor (L.) Moench] feed value. Rate of starch digestion is now commonly believed to be the limiting factor in sorghum utilization by cattle (Bos taurus). However, techniques to assess this trait are not useful to sorghum breeders because of high labor inputs, lab error associated with starch measurement, and need for high numbers of replications. The objective of this study was to develop a simple technique capable of identifying differences in digestion between sorghum and corn (Zea mays L.) …

Accumulation Of Heavy Metals By Vegetables Grown In Mine Wastes, George P. Cobb, Kristin Sands, Melissa Waters, Bobby G. Wixson, Elaine Dorward-King

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Lead, cadmium, arsenic, and zinc were quantified in mine wastes and in soils mixed with mine wastes. Metal concentrations were found to be heterogeneous in the wastes. Iceberg lettuce, Cherry Belle radishes, Roma bush beans, and Better Boy tomatoes were cultivated in mine wastes and in waste-amended soils. Lettuce and radishes had 100% survival in the 100% mine waste treatments compared to 0% and 25% survival for tomatoes and beans, respectively. Metal concentrations were determined in plant tissues to determine uptake and distribution of metals in the edible plant parts. Individual soil samples were collected beneath each plant to assess …

An Assessment Of On-Line Package Customization For Sheet Size Products Packaged In Paperboard Envelopes, Kevin Kennedy

Theses

This study evaluates the on-line printing of paperboard envelopes as a means of supporting the need to provide customized packaging. Market forces and new business models are contributing to the need for customized packaging and rapid response to orders. Large retailers are demanding unique packaging presentations and global marketing requires localized packaging for different regions of the world. A business environment ofjust-intime delivery and minimal inventory levels demand flexibility to react to unpredictable product mix and volumes. These conditions require customized packaging within short cycle times. The traditional carton printing process using offset lithography does not respond quickly enough to …

Evaluation Of Packaging Materials Under Vacuum For Potential Use As Internal Cushioning For Semiconductor Industry Vacuum Machinery, Andrew Baisch

Theses

This study explores a concept for applying basic packaging materials to an environment of high vacuum. This study identified three basic packaging materials and exposed them to a high vacuum environment to identify visual effects caused by the vacuum. In semiconductor and data storage industries, the machinery needed to ultimately create a computer chip often contains vacuum chambers. A common practice of the industry is to ship this machinery while under a state of high vacuum. There are parts inside these vacuum chambers that need protection from the effects of shock and vibration. By placing a sample of packaging material …

Monaural Cue Sound Localizer, John G. Harris, Chiang Jung Pu, Jose C. Principe

Electrical and Computer Engineering Faculty Research & Creative Works

We describe the first single microphone sound localization system and its inspiration from theories of human monaural sound localization. Reflections and diffractions caused by the external ear (pinna) allow humans to estimate sound source elevations using only one ear. Our single microphone localization model relies on a specially shaped reflecting structure that serves the role of the pinna. Specially designed analog VLSI circuitry uses echo-time processing to localize the sound. A CMOS integrated circuit has been designed, fabricated, and successfully demonstrated on actual sounds.

New Buffer Layers, Large Band Gap Ternary Compounds: Cualte², K. Benchouk, E. Benseddik, C. O. El Moctar, J. C. Bernède, S. Marsillac, J. Pouzet, A Khellil

Electrical & Computer Engineering Faculty Publications

After deposition, by evaporation under vacuum, of Al/Cu/Te, multilayer structures, annealing at 673 K or more for half an hour, under argon flow, allows CuAlTe2 films crystallized in the chalcopyrite structure to be obtained. The optical and electrical properties are interpreted by introducing the influence of impurity foreign phases present in the films. The optical properties are sensitive to the small Al2O3 domains randomly distributed into the CuAlTe2 polycrystalline matrix. The optical band gap is slightly increased (2.35 eV) by the presence of alumina. The conductivity measurements show that a short circuit effect can be induced by a binary Cu2-xTe …

‘Weihing’ Great Northern Disease-Resistant Dry Bean, Dermot P. Coyne, D.S. Nuland, Dale T. Lindgren, James R. Steadman, D.W. Smith, J. Gonzales, J. Schild, J. Reiser, Lisa Sutton, Clay Carlson, J.R. Stavely, P. Miklas

Department of Agronomy and Horticulture: Faculty Publications

Nebraska is the leading provider in the United States of Great Northern (GN) dry beans (Phaseolus vulgaris L.). Rust [(Uromyces appendiculatus (Pers.) Unger], common bacterial blight [(Xanthomonas campestris pv. phaseoli (Smith) Dye] (Xcp), and white mold [Sclerotinia sclerotiorum (Lib.) de Bary] diseases cause serious reductions in bean yield and seed quality in Nebraska. Halo blight (Pseudomonas syringae pv. syringae van Hall) has been observed in some years, but is not considered a major problem. Diseaseresistant cultivars should ensure improved seed yields and yield stability, and seed quality, and reduce pesticide application. Upright growth habit, combined …

Using A Nitrate Specific Ion Electrode To Determine Stalk Nitrate–Nitrogen Concentration, Wallace Wilhelm, S.L. Arnold, James S. Schepers

Department of Agronomy and Horticulture: Faculty Publications

The end-of-season stalk NO₃ test has been used to determine N sufficiency in corn (Zea mays L.). Nitrate concentration is commonly determined with flow-injection analysis (FIA), which is accurate but uses hazardous chemicals and is time-consuming. Use of a simpler method of NO₃ determination, such as the NO₃ specific ion electrode (SIE), may save time and costs, and reduce hazards. The objective of this study was to compare estimates of stalk NO₃ concentration by FIA and NO₃ SIE. For FIA, NO₃ was extracted with 2 M KCl, and the extract was filtered before analysis. …

Using Δe Distribution As A Predictor Of Digital Proofing Performance, Raul Eduardo Gonzalez Dorbecker

Theses

The performance of color matching in ICC-based Color Management Systems (CMS) is being improved, and its workflow established. As part of the digital workflow, digital proofing plays an important roll in the control of color from capture to the printed page, but its method of evaluation is not clearly understood.

To evaluate the degree of color matching by digital proofing in an ICC-based CMS between a reference image and a sample image, the [formula] calculated by averaging the individual color differences is being used. Doing a qualitative evaluation, ICC-based CMS should be able to stand behind the statement that the …

Residency Status And Age Of Entry As Moderators Of The Effectiveness Of A Special Act School District, Sabrina Beckerink

Theses

This study investigated the effectiveness of the program at Randolph Academy Union Free School District, a special act school district designed to educate students with emotional, behavioral, and learning difficulties. The outcome of treatment is documented by measurement of change in academic achievement. Pre-post comparisons of standardized achievement test scores were collected from the psychoeducational files of 49 students. Results indicate significant gains in academic achievement. A two-way analysis of covariance identified age of entry into the program as a moderator of academic achievement: younger entrants improved their relative ranking more than older entrants.

Determination Of Thermal Maturity And Organic Matter Type By Principal Components Analysis Of The Distributions Of Polycyclic Aromatic Compounds, Michael A. Kruge

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

The thermal maturity and organofacies sensitivity of polycyclic aromatic compound (PAC) distributions was explored by examination of the aromatic fractions of solvent extracts from a diverse set of 53 shales, coals and kerogen macerals which have undergone either natural or artificial maturation and which represent all three principal sedimentary organic matter (OM) types. Systematic changes with maturation were observed in the following groups of isomers: tri- and tetramethylnaphthalenes, methyl- and dimethylphenanthrenes, methyl- and dimethyldibenzothiophenes, methylpyrenes, and methylchrysenes. The maturity differences were quantified by mathematical ratios of the relative concentrations of the more thermally stable isomers to the less stable, on …

Detection And Modeling Of Radiation Induced Effects In Tissues By Dielectric Spectroscopy, Dorin A. Todor

Physics Theses & Dissertations

The work presented here is applied physics research in the field of radiation treatment. We address the development of a new and innovative method, in vivo and possibly non-invasive, for tumor and healthy tissues control during and after the radiation treatment. The radiation treatment is delivered in an almost standardized manner for particular classes of tumors. The large variance in the individual radio sensitivity of healthy tissues and tumors often leads to local recurrence of neoplastic growth and/or distant metastatic disease which often remains untreated. The method is based on the measurement and analysis of electrical impedance data in …

Robust Adaptive Critic Based Neurocontrollers For Systems With Input Uncertainties, S. N. Balakrishnan, Zhongwu Huang

Mechanical and Aerospace Engineering Faculty Research & Creative Works

A two-neural network approach to solving optimal control problems is described in this study. This approach called the adaptive critic method consists of two neural networks: one is called the supervisor or critic, and the other is called an action network or controller. The inputs to both these networks are the current states of the system to be controlled. Each network is trained through an output of the other network and the conditions for optimal control. When their outputs are mutually consistent, the controller network output is optimal. The optimality is limited to the underlying model. Hence, we develop a …
