Inner Presence, Amy L. Bailey

Dissertations and Theses @ UNI

What we believe constructs the person we are and will become, the ways and means we conduct our lives and form our sense of right and wrong at all levels inward and outward: politically, socially, and personally. My own beliefs, founded on my faith in God, have directed me in my work. This thesis exhibition is an exploration of how to express these beliefs visually. During my exploration, I had to alter and develop my own visual iconography to express my ideas of God. Conventional transcendent icons including the cross, the 1 Christ figure, and the Virgin Mary, have been …

The Effects Of Computer Animations On Secondary Students’ Understanding Of The Crushing Can Chemical Demonstration, Resa Marie Kelly

Dissertations and Theses @ UNI

Understanding chemistry requires the ability to think at three different levels: submicrochemistry, macrochemistry, and representational chemistry. Students often have difficulty making connections among these three areas due to the abstract nature of many chemistry concepts. The purpose of this paper is to investigate how computer animations affected secondary students' understanding of the Crushing Can Demonstration. This investigation compared two groups of chemistry students at a large, suburban high school. The treatment group viewed the animation after seeing and discussing the crushing can demonstration, while the control group received the same instruction as the treatment group but did not see the …

A Structure-Model For The Hamlet-Tradition, Christopher Scott Chiron

Dissertations and Theses @ UNI

The "hero-as-fool" structure-model for the Hamlet-story proposed by William F. Hansen is modified into an "Amlethan" structure-model with five major elements: ( 1) the Usurpation; (2) the First Test (of the Maiden); (3) the Second Test (of the Mother); (4) the Third Test (of the Journey); and (5) the Revenge. The first and last elements emphasize the "avenging son" aspect of the story whereas the middle three elements emphasize the "hero-as-fool" aspect. The Amlethan structure-model is then re-applied to the two "essential" texts in the tradition, Saxo Grammaticus' narrative of Amleth (c. 1200) and William Shakespeare's play Hamlet (c. 1600). …

Automated Identification Of The Operational Modes Of Switched Electric Circuits, J. Jatskevich, O. Wasynczuk, E. A. Walters, C. E. Lucas, Steven Pekarek, P. T. Lamm

Electrical and Computer Engineering Faculty Research & Creative Works

In the analysis of power-electronic-based energy conversion systems, it is important to identify the operational modes of the associated converters and inverters. However, as the number of switching elements increases, it becomes more difficult to analytically establish all possible modes of operation. In this paper, a modelling technique is described wherein a state-space representation of the overall system is generated automatically and updated dynamically as each new topology is encountered. Utilizing this approach, it becomes possible to identify the operational modes of converters and inverters based upon the cyclically repeated sequences of topologies that can be observed during steady-state operation. …

Development Of A Functional Basis For Design, Robert B. Stone, Kristin L. Wood

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Functional models represent a form independent blueprint of a product. As with any blueprint or schematic, a consistent language or coding system is required to ensure others can read it. This paper introduces such a design language, called a functional basis, where product function is characterized in a verb-object (function-flow) format. The set of functions and flows is intended to comprehensively describe the mechanical design space. Clear definitions are provided for each function and flow. The functional basis is compared to previous functional representations and is shown to subsume these attempts as well as offer a more consistent classification scheme. …

Who Changed Their Minds About Erap? Hypothesis Tests Based On Design-Consistent Estimates Of An Ordered Probit Model Of The Philippine President’S Ratings, Michael M. Alba, Geriz Bigol, Reina Filipina Deacosta, Ria Pulumbarit

Angelo King Institute for Economic and Business Studies (AKI)

Using data from the March and June 1999 surveys of the Social Weather Stations (SWS), we generate and analyze design-based estimates of the subpopulation means and standard deviations of President Estrada’s ratings and of his net satisfaction index over certain respondent characteristics. We also estimate the parameters of a design-consistent ordered probit model of the ratings and compare the coefficient estimates as well as the marginal effects on the ratings probabilities of the March and June regressors to identify the respondent attributes that contributed to the net decline in his popularity. We find that although the estimates of the population …

A Survey Of Iowa High School Band Directors And Their Students On The Occurrences Of Performing On A Musical Instrument While Experiencing Pain, Crystal M. Franzen Halverson

Working Memory And Human Reasoning : An Individual Differences Approach, Alison Jayne Capon

School of Psychology Theses

Experiments 1-3 investigated the relationship between working memory and syllogistic and five-ten-n series spatial inference. A secondary aim was to replicate the findings of Shah and Miyake (1996) who suggested the use of separate central resources of working memory for spatial and verbal ability. The correlational analysis showed that the complex verbal and spatial working memory span tasks were associated together and consistently predicted reasoning performance in both verbal and visual modalities. The confirmatory factor analysis showed that three factors best accounted for the data -a verbal, a spatial, and a general resource. All the span tasks and most of …

Adaptive Information Filtering: Evolutionary Computation And N-Gram Representation, Daniel R. Tauritz, Ida G. Sprinkhuizen-Kuyper

Computer Science Faculty Research & Creative Works

Adaptive Information Filtering (AIF) is concerned with filtering information streams in changing environments. The changes may occur both on the transmission side (the nature of the streams can change) and on the reception side (the interests of a user can change). The research described in this paper details the progress made in a prototype AIF system based on weighted n-gram analysis and evolutionary computation. A major advance is the design and implementation of an n-gram class library allowing experimentation with different values of n instead of solely with 3-grams as in the past. The new prototype system was tested on …
