Atomic Hydrogen Cleaning Of Inp(100) For Preparation Of A Negative Electron Affinity Photocathode, K. A. Elamrawi, M. A. Hafez, H. E. Elsayed-Ali

Electrical & Computer Engineering Faculty Publications

Atomic hydrogen cleaning is used to clean InP(100) negative electron affinity photocathodes. Reflection high-energy electron diffraction patterns of reconstructed, phosphorus-stabilized, InP(100) surfaces are obtained after cleaning at ∼400 °C. These surfaces produce high quantum efficiency photocathodes (∼8.5%), in response to 632.8 nm light. Without atomic hydrogen cleaning, activation of InP to negative electron affinity requires heating to ∼530 °C. At this high temperature, phosphorus evaporates preferentially and a rough surface is obtained. These surfaces produce low quantum efficiency photocathodes (∼0.1%). The use of reflection high-energy electron diffraction to measure the thickness of the deposited cesium layer during activation by correlating …

Reflective Remote Method Invocation, George K. Thiruvathukal, Lovely S. Thomas, Andy T. Korczynski

Computer Science: Faculty Publications and Other Works

Remote Method Invocation (RMI) is available in the current Java language design and implementation, providing the much-needed capability of allowing objects running in different Java processes to collaborate using a variation on the popular Remote Procedure Call (RPC).

Although RMI provides features which are desirable for high-performance distributed computing, its design and implementation are deficient in key areas of importance to the high-performance computing community in general. This paper addresses the key deficiencies of RMI and how these deficiencies affect the design and implementation of distributed object applications.

Reflective RMI (RRMI) is an open RMI implementation which makes better use …

Wide-Area Implementation Of The Message Passing Interface, Ian Foster, Jonathan Geisler, William Gropp, Nicholas Karonis, Ewing Lusk, George K. Thiruvathukal, Steven Tuecke

Computer Science: Faculty Publications and Other Works

The Message Passing Interface (MPI) can be used as a portable, high-performance programming model for wide-area computing systems. The wide-area environment introduces challenging problems for the MPI implementor, due to the heterogeneity of both the underlying physical infrastructure and the software environment at different sites. In this article, we describe an MPI implementation that incorporates solutions to these problems. This implementation has beenconstructed by extending the Argonne MPICH implementation of MPI to use communicationservices provided by the Nexus communication library and authentication, resource allocation, process creation/management, and information services provided by the I-Soft system (initially) and the Globus metacomputing toolkit …

A Visual Design Method And Its Application To High Reliability Hypermedia Systems, Robert Malcolm Newman

Other Faculty of Science and Engineering Theses

This work addresses the problem of the production of hypermedia documentation for applications that require high reliability, particularly technical documentation in safety critical industries. One requirement of this application area is for the availability of a task-based organisation, which can guide and monitor such activities as maintenance and repair. In safety critical applications there must be some guarantee that such sequences are correctly presented. Conventional structuring and design methods for hypermedia systems do not allow such guarantees to be made. A formal design method that is based on a process algebra is proposed as a solution to this problem. Design …

An Investigation Of The Sculpture/Language Homology, Peter Reginald Pay

Other Faculty of Arts, Humanities and Business Theses

This research is concerned with the implications of reading sculpture as a mode of communication that is indicative of an art/language homology. An investigation of the inter-relationship of the functions of ‘Language’ and 'Conventions of Visual Communication' is viewed against contemporary redefinitions of the role of sculpture, its character of presentation and mode of engagement with respondents. Theoretical investigation examines models of communication and identifies corresponding systems in an art that is exemplified by the sculpture of Tony Cragg. Cragg's significantly organised collections of commonplace objects, presenting the visual assertiveness of the 'ready-made' prompt a reconsideration of the object as …

Assessing The Learning Needs Of Adults With Acquired Physical Disability In Vocational Rehabilitation, Kathleen E. Mennen

Masters Theses

It is difficult to ascertain the learning needs of adults with acquired physical disability in vocational rehabilitation. The onset of the disability reactivates and/or creates various psychological, social, and educational problems in the learner’s life, which makes assessing his learning needs more complex. This study discusses the particular challenges of assessing the learning needs of this population. It also describes the development and use of a screening tool with which to make objective decisions in selecting assessments for this population.

The Inter-Relatedness Of Nutrition, Menstrual Status, Lean Body Mass, And Injury Among High School Female Varsity Basketball Players, Megan Jean Pavlak, Robyn Kristina Smith, Kristie Ann Wood

Masters Theses

Basketball is one of the highest risk sports for injury, especially for the female population. Studies have been performed looking at intrinsic and extrinsic factors that may contribute to an increased injury rate among female athletes. This study focused on nutrition, menstrual status, lean body weight and injury in female high school varsity basketball athletes (n=138). Nutritional and menstrual surveys were administered to these athletes. The athletes’ body fat percentages were measured and calculated into lean body weight. Injuries were documented for one season. No clinically significant relationships were found among the variables. Descriptive data concerning nutrition, injury, menstrual status, …

Temperature Dependence Of Step Density On Vicinal Pb(111), Z. H. Zhang, H. E. Elsayed-Ali

Electrical & Computer Engineering Faculty Publications

The temperature dependence of step density on the vicinal Pb(111) surface is investigated using reflection high-energy electron diffraction. When the temperature is increased from 323 to 590 K. the average terrace width and the average string length at the step edge decrease from 85±25 to 37±16 Å and from 220±33 to 25±8 Å, respectively. Thermal step collapse on the Pb(111) surface near its bulk melting temperature is not observed. Above 530±7 K, the change in the string length at the step edge with temperature becomes small, and the intensity of the (00) beam is significantly decreased. We conclude that partial …

The Effects Of Acceleration On The Attitudes Toward And Achievement In Mathematics, Nancy Preece Mcgill

Graduate Research Papers

This study examined the affects of participation in accelerated mathematics classes on the attitudes toward and the achievement in mathematics of thirty-five seventh, eighth, and ninth grade students and their parents. The respondents, from a small rural school district, completed a survey consisting of an open-form question and ten statements designed to elicit perceptions regarding their attitudes toward and achievement in mathematics.

Results indicated that parental attitudes were significantly more positive than students as a result of participation. Results also showed that participation produced no harmful effects and, in fact, many respondents expressed a desire to continue taking accelerated classes. …

Poetry For Young Adults: A Textual Analysis Of Poems By Mel Glenn And Paul Janeczko, Lisa Pope

Graduate Research Papers

The purpose of this study is to determine the prevalent characteristics and elements of young adult poetry by examining a random sample of poems by Mel Glenn and Paul Janeczko. The characteristics and elements include themes, subjects, and other items of apparent relevance to teenagers' lives.

Because poems are the data being studied, a qualitative approach is utilized. More specifically, textual analysis is employed because this type of analysis is focused upon text.

The findings show that both sets of poetry contain similar elements and characteristics. All poems studied are of high poetic merit, contain imagery, are relatively simple, and …

Biomineralization Of Magnetic Iron Minerals In Bacteria, Richard B. Frankel, Dennis A. Bazylinski, Dirk Schϋler

Physics

Magnetotactic bacteria orient and migrate along magnetic field lines. This ability is based on a submicron assembly of single-magnetic domain iron mineral particles that elegantly solves the problem of how to construct a magnetic dipole that is large enough to be oriented in the geomagnetic field at ambient temperature, yet fit inside a micron-sized cell. The solution is based on the ability of the bacteria to accumulate high concentrations of iron, and control the deposition, size and orientation of a specific iron mineral at specific locations in the cell.

Who Won The 1996 Nhl Plus-Minus Award?, William (Bill) H. Williams, David A. Williams

Publications and Research

Point total, goals plus assists, is an NHL player’s most important individual statistic; it is the best predictor of salary. However, an individual player's goals and assists are only indirectly important to his team because the team objective is to win games and not necessarily to watch individual players run up their point totals. Unfortunately, sometimes opposition teams score easy goals against a team's best goal scorers because these players do not always play well defensively.vAs a result of this conflict, hockey uses a statistic called the "plus/minus," (P/M), which purports to measure a player's offensive versus defensive ability.

A Framework For Understanding Social Science Contributions To Ecosystem Management, Joanna Endter-Wada, Dale Blahna, Richard Krannich, Mark W. Brunson

Environment and Society Faculty Publications

We propose a framework for understanding the role that the social sciences should play in ecosystem management. Most of the ecosystem management literature assumes that scientific understanding of ecosystems is solely the purview of natural scientists. While the evolving principles of ecosystem management recognize that people play an important role, social considerations are usually limited to political and decision-making processes and to development of environmental education. This view is incomplete. The social science aspect of ecosystem management has two distinct components: one that concerns greater public involvement in the ecosystem management decision-making process, and one that concerns integrating social considerations …

Aegis Data Analysis And Reduction (Adar) In Support Of The Aegis Weapon System (Aws), June Bullard Gaines

Theses and Dissertations

The AEGIS Weapons System (AWS), part of the AEGIS Combat System (ACS), is an integral part of the defense system on U.S. Navy AEGIS-class ships. AEGIS Data Analysis and Reduction (ADAR) has been developed to assist in the evaluation of the AWS data. ADAR, along with the AWS and ACS, has evolved through the years to accommodate advances in technology and computer programming languages. Additionally, ADAR has evolved so that users located at sites other than the Naval Surface Warfare System Dahlgren Division (NSWCDD), Dahlgren, Virginia, can reduce tactical system data and perform data analysis using the reduced data.
