New Complexities In The Low-State Line Profiles Of Am Herculis, S. Kafka, T. Ribeiro, R. Baptista, R. K. Honeycutt, Jeff W. Robertson

Faculty Publications - Physical & Earth Sciences

When accretion temporarily ceases in the polar AM Her, the emission-line profiles are known to develop several distinct components, whose origin remains poorly understood. The new low-state spectra reported here have a more favorable combination of spectral resolution (R ~ 4500), time resolution (~ 3 minute exposures), and S/N than earlier work, revealing additional details of the orbital dependence of the line profiles. The central strong feature of Hα is found to be composed of two components of similar strength, one having K ~ 100 km s-1 and phased with the motion of the secondary star, the other having little …

Design, Fabrication, Modeling And Characterization Of Electrostatically-Actuated Silicon Membranes, Brian C. Stahl

Master's Theses

This thesis covers the design, fabrication, modeling and characterization of electrostatically actuated silicon membranes, with applications to microelectromechanical systems (MEMS). A microfabrication process was designed to realize thin membranes etched into a silicon wafer using a wet anisotropic etching process. These flexible membranes were bonded to a rigid counterelectrode using a photo-patterned gap layer. The membranes were actuated electrostatically by applying a voltage bias across the electrode gap formed by the membrane and the counterelectrode, causing the membrane to deflect towards the counterelectrode. This deflection was characterized for a range of actuating voltages and these results were compared to the …

Moving Towards Illumination? The Development Of Method And Rhetoric In The American School Of Archaeologists, Jeremy R. Brown

Seminary Masters Theses

This thesis examines two aspects of the work the American School of archaeologists: 1) their refinements of archaeological method; and 2) their cultivation of a particular rhetorical strategy to describe the significance of their findings In the first chapter, we explore the rise of Near Eastern archaeology from the mid-nineteenth century through the early-twentieth century. During this time many communities of faith joined in the digging in hopes of locating finds with biblical implications. A lofty rhetoric was developed to describe these discoveries and to relate their impact upon the accounts of the Bible. This period was marked by the …

The Formal Structure Of Metaphysics And The Importance Of Being Earnest, Jeremy Barris

Humanities Faculty Research

This article considers how the formal structure of metaphysical thought is displayed in Oscar Wilde's Importance of Being Earnest. One frequent aim of metaphysics is to understand the world as a whole. We cannot gain such a global vantage point without separating ourselves from all the particular meanings things have for us within the world. But we start within the world, and so can only proceed on the basis of those particular meanings. Consequently we can only separate ourselves from them if they work to cancel themselves in favor of the global understanding. When the separate range of meanings is …

Immigrants, Cultural Distance And Us State-Level Exports Of Cultural Products, Roger White, Bedassa Tadesse

Economics

We examine the relationships between immigrants, cultural distance and state-level exports, employing state-specific immigrant stocks and total US immigrant stocks, separately, and a measure of cultural distance recently introduced by [Tadesse, B., & White, R. (2008b). Cultural distance as a determinant of bilateral trade flows: Do immigrants counter the effect of cultural distance? Applied Economic Letters]. A positive link between immigrants and aggregate exports is reported and, while cultural distance is found to reduce exports, immigrants partially offset the effects of cultural distance by increasing both the intensity of existing exports and the likelihood that exporting occurs. However, heterogeneity in …

Coming Together: The Pros And Cons Of School Consolidation, David Alan Dolph

Educational Leadership Faculty Publications

The viability and acceptability of consolidation— combining two or more school buildings or districts into a single entity—have ebbed and flowed over the years. In the early 1900s, the main targets of school consolidation were the rural schools. The education leaders and policy makers of the time believed that a centralized model in which all schools looked alike would prove to be the best approach for educating youth to be productive citizens (Kay, Hargood, and Russell 1982).

In addition to providing an expanded curriculum, they believed, consolidated schools could be operated more efficiently and economically—an idea that has continued to …

Mapping Reality Into Virtual Worlds, Josh Mcfarlane

Computer Science and Computer Engineering Undergraduate Honors Theses

As virtual worlds become more prevalent, they become increasingly useful as a means of information dissemination. This thesis examines the possible connections between real world objects and their virtual world counterparts. We look at how, by attaching sensors to an object, or by using a smart object with embedded sensors, the information can be relayed to a server. From this information, it will be possible to create a duplicate object in the virtual world and have it mirror the real world object in terms of state and movement. Almost all current solutions for remotely viewing a room or area are …

A Comparison Of Two Probability Encoding Methods: Fixed Probablity Vs. Fixed Variable Values, Ali E. Abbas, David V. Budescu, Hsiu-Ting Yu, Ryan Haggerty

Psychology Faculty Publications

We present the results of an experiment comparing two popular methods for encoding probability distributions of continuous variables in decision analysis: eliciting values of a variable, X, through comparisons with a fixed probability wheel and eliciting the percentiles of the cumulative distribution, F(X), through comparisons with fixed values of the variable. We show slight but consistent superiority for the fixed variable method along several dimensions such as monotonicity, accuracy, and precision of the estimated fractiles. The fixed variable elicitation method was also slightly faster and preferred by most participants. We discuss the reasons for its superiority and conclude with several …
