Reducing Cognitive Overheads In A Web Warehouse Using Reverse-Osmosis, Sanjay Kumar Madria, Wee Keong Ng, Ee-Peng Lim, Sourav S. Bhowmick

Computer Science Faculty Research & Creative Works

This paper provides a quantitative analysis of reducing cognitive overheads in a Web warehouse using an important class of operation called reverse osmosis. The analysis is used to examine two different cognitive overheads of locating relevant nodes or information and display time of a Web table. A reverse-osmosis operation enables us to eliminate in relevant information from a collection of Web documents stored in the form of a Web table. We call such an operation reverse-osmosis because it is analogous to the reverse osmosis process in the field of water purification. We discuss a formal algorithm of the reverse-osmosis operation

Ethics Exercises For Civil, Environmental, And Geological Engineers, Paul Michael Santi

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

The practices of civil, environmental, and geological engineering share many common ethical dilemmas. These fields typically require extensive interaction with clients and regulatory agencies, while dealing with unpredictable earth materials for design and uncertain design parameters. Consequently, a capstone design course must address not only technical issues, but also a wide range of ethical and behavioral issues. This study presents a series of exercises used in the classroom to teach these issues through dealing with "gray" ethical areas, concepts of advocacy and the use of compromise, relating specific stories to global concepts, proper behavior in the corporate environment, and the …

Dolomitization And Dolomite Neomorphism: Trenton And Black River Limestones (Middle Ordovician) Northern Indiana, U.S.A., M. I N Chan, Jay M. Gregg, Kevin L. Shelton

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

The Trenton and Black River Limestones are dolomitized extensively along the axis of the Kankakee Arch in Indiana, with the proportion of dolomite decreasing to the south and southeast of the arch. Planar and nonplanar dolomite replacement textures and rhombic (type 1) and saddle (type 2) void-filling dolomite cements are present. Three stages of dolomitization, involving different fluids, are inferred on the basis of petrographic and geochemical characteristics of the dolomites. Nonferroan planar dolomite has relatively high δ18O values (-1.8 to -6.1‰ PDB) and has ⁸⁷Sr/⁸⁶Sr ratios (0.70833 to 0.70856) that overlap those of Middle Ordovician seawater. …

Border Detection On Digitized Skin Tumor Images, Z. Zhang, William V. Stoecker, Randy Hays Moss

Chemistry Faculty Research & Creative Works

A radial search technique is presented for detecting skin tumor borders in clinical dermatology images. First, it includes two rounds of radial search based on the same tumor center. The first-round search is independent, and the second-round search is knowledge-based tracking. Then a rescan with a new center is used to solve the blind-spot problem. The algorithm is tested on model images with excellent performance, and on 300 real clinical images with a satisfactory result

Enantiomeric High-Performance Liquid Chromatographic Separation Of Β- Substituted Tryptophan Analogues, G. Török, A. Péter, E. Vékes, J. Sápi, M. Laronze, J. Y. Laronze, Daniel W. Armstrong

Chemistry Faculty Research & Creative Works

The high-performance liquid chromatographic enantioresolution of β- substituted tryptophan analogues by direct and indirect methods is reported. The direct separation was carried out on chiral crown ether-bonded, on the macrocyclic antibiotic teicoplanin-bonded or on different derivatized β- cyclodextrin-bonded phases. The indirect resolution was achieved by applying pre-column derivatization with the chiral reagents 1-fluoro-2,4- dinitrophenyl-5-L-alanine amide (FDAA) and 2,3,4,6-tetra-O-acetyl-β-D- glucopyranosyl isothiocyanate (GITC). In the separation of all four isomers of the analytes, the indirect methods seemed to be more efficient than the direct methods. In most cases, the FDAA derivatives of the stereoisomers could be separated with better selectivity in methanol-containing …

Adaptive Critic Based Neurocontroller For Turbogenerators With Global Dual Heuristic Programming, Ganesh K. Venayagamoorthy, Donald C. Wunsch, Ronald G. Harley

Electrical and Computer Engineering Faculty Research & Creative Works

Turbogenerators are nonlinear time varying systems. This paper presents the design of a neurocontroller for such a turbogenerator that augments/replaces the traditional automatic voltage regulator (AVR) and the turbine governor using a novel technique based on the adaptive critic designs (ACDs) with emphasis on global dual heuristic programming (GDHP). Simulation results are presented to show that the neurocontroller derived with the GDHP approach is robust and its performance is better when compared with that derived with other neural network technique, especially when system conditions and configuration changes.

Analysis Of A Novel Four-Level Dc/Dc Boost Converter, Keith Corzine, Sonal K. Majeethia

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, novel two-quadrant buck/boost and one-quadrant boost four-level DC/DC power converters are introduced. The primary application for these converters is that of interfacing a low-voltage DC source, such as a fuel cell or battery, to a high-voltage four-level inverter. One important feature of the four-level DC/DC power converters proposed is the ability to perform the power conversion and balance the inverter capacitor voltages simultaneously. With the capacitor voltage balancing, it is possible to obtain the full voltage from the inverter. For the boost converter, the steady-state and nonlinear average-value (NLAM) models are developed. The NLAM is verified against …

Claiming The Victim: Tokenism, Mourning, And The Future Of German Holocaust Poetry, Kathrin M. Bower

Languages, Literatures, and Cultures Faculty Publications

This excerpt from Nelly Sachs's poem "You Onlookers" could be read as support for the contention, reportedly made by Adolf Hitler during a table talk, that "The Jews invented conscience." This statement, although fascinating in itself for what it implies about Hitler's psyche and moral sense, becomes even more provocative if read in association with Marina Zwetajewa's puzzling proclamation, made famous by its appearance as an epigram to a poem by Paul Celan, that "all poets are Jews." The connection of Jews to both conscience and poetry has significant repercussions for the genre of so-called Holocaust lyric, so-called because it …

The Double Edged Sword Of Depersonalization: An Examination Of Depersonalization's Role In The Police Profession, Michael J. O'Connor

Dissertations and Theses @ UNI

The role of depersonalization is the central focus of this study. A major issue in examining the role of depersonalization is whether the present concept of burnout is an appropriate indicator of bumout for police officers. The commonly accepted conception of burnout is a process of emotional exhaustion that leads to depersonalization, followed by a reduction in work accomplishment. Depersonalization, by this conception, is a symptom of burnout. By definition,depersonalization is the psychological distancing of emotional and psychological trauma in stressful situations—a coping technique.

For police officers, depersonalization acts as a shield of emotional armor to maintain a sense of …

Photodecomposition Of Crystal Violet Dye In Water Solution And Suspensions Of Metal Oxides, Tatiana Yurievna Zakharian

Dissertations and Theses @ UNI

Photodecomposition and photodecolorization of crystal violet dye were studied in water solution, hydrogen peroxide solution and suspensions of metal oxides. Spectroscopic evidence for the formation of methylated pararosanilines and demethylated derivatives of Michler's ketone as the reaction intermediates was obtained for the photodecomposition of crystal violet in water solution. The mechanism of formation of the intermediates was discussed in terms of charges of individual atoms calculated using Spartan software.

Photooxidation of crystal violet was shown to occur faster in hydrogen peroxide solution due to the higher oxidation potential of hydrogen peroxide and hydroxyl radicals. A mechanism similar to photooxidation in …

Principal Succession: Realities Encountered By Successor Principals During The Succession Process, Kenneth Lester Rigdon

Dissertations and Theses @ UNI

In order to better understand the realities of principal succession (an interactive sequencing process for changing school administrators) it was the purpose of this study to examine the relationship between four organizational frames (structural, human resource, political, and symbolic) delineated by Bolman and Deal (1997) and three traits noted in the literature as evident during school principal succession (predecessor leave-taking, succession source, and experience). There is little research regarding school principal succession, and concern exists regarding the adequacy of transition practices within organizations. A questionnaire was employed to survey all school principals in the state of Kansas who succeeded during …

The Effect Of Heat On Fingertip Sensitivity Of Meat Processing Workers, Brian James Finder

Dissertations and Theses @ UNI

Current research indicates that acute non-freezing cold exposure elicits short-term performance problems; namely reduced upper extremity temperature, blood flow, tactile sensitivity, and dexterity. However, various animal-related studies indicate that humans are at increased risk of incurring semi-permanent upper extremity nervous system dysfunction as a result of repeated cold exposure.

The purpose of this research was to examine various factors that may contribute to hand/arm nervous system impairment of individuals who work in a refrigerated meat-processing environment. The methodology used was primarily the Experimental Method and from studies conducted by other researchers, was driven by the following questions:

Managing The Information Overload : A Case Study Of Managerial Staff In A Government Department, Kerttu Hamilton

Theses: Doctorates and Masters

Research shows that the amount of information has grown vastly and information technology has greatly increased its availability. This has caused changes in the organisational environment, placing greater and greater demands on the individuals' and organisations' capacity to absorb and process information. Since information is considered to be a valuable and necessary asset, and as time for processing information is limited, an individual will have to make choices about what information to process. An exploratory case study was conducted to ascertain what rationale do individuals in an organisational setting use for making decisions about what information to process from the …

Community Attitudes And The Role Of The Victim Offender Relationship In Child Sexual Abuse Cases, Kirstin Leigh Bouse

Theses: Doctorates and Masters

Past research has illustrated that communily attitudes tend not to be reflected in crime legislation particularly when considering the victim-offender relationship and perceived seriousness of child sexual abuse. This study examined the effects of 4 different victimoffender relationships and the degree of trust within these relationships on perceptions of offence seriousness and emotional and physical harm, for the offence of indecently dealing with a 14-year old girl. One hundred and sixty community members used a 7- point scale to rate the degree of trust within these relationships, the seriousness of the offence and the emotional and physical harm suffered by …

Assessing Moral Reasoning Development Through Values Education Within A Western Australian Independent School, Kelvin Fairclough

Theses: Doctorates and Masters

The purpose of this thesis is to study the attitudes, practices and knowledge of Greek women in Perth, Western Australia, regarding cervical cancer screening. This is important because no study has yet examined the cervical screening pattern of this group, despite their low participation rate in screening programs. Qualitative semi-structured interviews among 15 Greek women in Perth were used for data collection. Interviews were conducted both in English and Greek. Eight out of the 15 women interviewed did not participate in frequent screening and many had had only one Pap test in their life. Culture and religion influenced negative attitudes …

Macroeconomic Announcements, Volatility And Interrelationships: An Examination Of The Uk Bond And Stock Markets, Bradley Jones

Theses : Honours

This study covers considerable ground and touches on a range of issues in a rigorous investigation of the intraday and end-of-day behaviour of I JK stock index and interest rate futures contracts. Firstly, the paper uses S-minute data in an initial examination of the response of the Short Sterling, Long Gilt and FTSEI00 to the release of macroeconomic announcements (assisted with the application of GMM). Secondly, in an analysis of intraday patterns in returns and volatility a GARCII(I,I) framework is employed, so that further inferences are made robust to time-varying variance. Finally, the paper draws upon some of the latest …

A Qualitative Investigation Into The Use Of The Internet In The Information Search Phase Of The Buying Decision Process, Kiaran Geen

There appears to be very little research on how consumer behaviour theories relate to the Internet. This study explored the extent to which the Internet is in the information search phase of the buying decision process, amongst Internet literate consumers. A qualitative investigation using virtual focus groups was conducted. …

The Term Structure Of Interest Rates In Australia : An Application Of Long Run Structural Modelling, Vicky Shimmings

Theses : Honours

The term structure of interest rates in Australia, using data of different types as well as frequencies covering the period 1991 (11) to 2000 (9), is investigated using a relatively new modelling strategy previously untested on Australian interest rate data. Developed by Pesaran & Shin (1997), this strategy incorporates long-run structural relationships in an otherwise unrestricted vector autoregression model (VAR). The long-run relationships included in the model are based on the Expectations Theory of the term structure. This model is then subjected to Granger-causality, generalised variance decompositions, generalised impulse response and persistence profile analysis, in the context of a vector …
