This thesis examines the modeling, analysis, and control system design issues for scramjet powered hypersonic vehicles. A nonlinear three degrees of freedom longitudinal model which includes aero-propulsion-elasticity effects was used for all analysis. This model is based upon classical compressible flow and Euler-Bernouli structural concepts. Higher fidelity computational fluid dynamics and finite elementmethods are needed formore precise intermediate and final evaluations. The methods presented within this thesis were shown to be useful for guiding initial control relevant design. The model was used to examine the vehicles static and dynamic characteristics over the vehicles trimmable region. The vehicle has significant longitudinal …

Since scholars first turned their attention to the subject some eighty years ago, one major area of contention in the study of Anglo-Saxon wills has been the function of the written will within Anglo-Saxon culture. Verbal agreements, formalized through oral ceremonies and symbolic actions, were recognized as legally binding; however, many of these agreements were also recorded in writing. Many scholars argue that the written document was superfluous;oral ceremonies were written down only in the case of memory failure and the documents themselves had no real performative function. Others see the existence of the written will to be evidence of …

Prognostics and health management (PHM) is a method that permits the reliability of a system to be evaluated in its actual application conditions. This work involved developing a robust system to determine the advent of failure. Using the data from the PHM experiment, a model was developed to estimate the prognostic features and build a condition based system based on measured prognostics. To enable prognostics, a framework was developed to extract load parameters required for damage assessment from irregular time-load data. As a part of the methodology, a database engine was built to maintain and monitor the experimental data. This …

The following study evaluated the effectiveness of a self-monitoring strategy on independent work behavior. The three subjects were in first grade, seven years old, identified with mild mental retardation (MIMR), and had an Individualized Education Plan (IEP) with targeted functional academic and behavior goals. The purpose of this study was to investigate the effect of a self-monitoring strategy on on-task independent work behavior and task completion. The research sought to determine whether or not a self-monitoring strategy would affect on-task independent work behavior and task completion. A multiple baseline across subjects design was used. Data were collected using a frequency …

Continuous advancements in biomedical research have resulted in the production of vast amounts of scientific data and literature discussing them. The ultimate goal of computational biology is to translate these large amounts of data into actual knowledge of the complex biological processes and accurate life science models. The ability to rapidly and effectively survey the literature is necessary for the creation of large scale models of the relationships among biomedical entities as well as hypothesis generation to guide biomedical research. To reduce the effort and time spent in performing these activities, an intelligent search system is required. Even though many …

The existing compact models can reproduce the characteristics of MOSFETs in the temperature range of -40oC to 125oC. Some applications require circuits to operate over a wide temperature range consisting of temperatures below the specified range of existing compact models, requiring wide temperature range compact models for the design of such circuits. In order to develop wide temperature range compact models, fourteen different geometries of n-channel and p-channel MOSFETs manufactured in a 0.18μm mixed-signal process were electrically characterized over a temperature range of 40 K to 298 K. Electrical characterization included ID-VG and ID-VD under different drain, body and gate …

ABSTRACT This study explored the functions of dialogue in emerging adults' moral turning points. Through purposive sampling, the researcher interviewed 10 emerging adults between 25 and 30 years old about experiences of turning point conversations during the years of 18 and 25. This study employed constant comparative and grounded theory methodologies to analyze messages reported in memorable conversations during this period. Results indicated that dialogue functioned to educate, disturb, and maintain emerging adults' moral perception during this period of moral reorientation. Subcategories under each included dialogue that functioned to explain, invite, warn, direct or instruct, challenge, persuade, agitate, expose, inquire, …

The purpose of this study was to explore current pedagogical approaches of undergraduate directing curricula in selected U.S. institutions of higher learning. Building on the work of Clifford Hamar and Anne Fliotsos, the thesis builds a foundation for further study of contemporary directing pedagogy. Fourteen course syllabi were collected voluntarily from members of The Association for Theatre in Higher Education (ATHE) and served at the primary source material. They were interpreted and analyzed qualitatively for components that identified the methods and philosophies of the instructor and/or institution. From these syllabi, the researcher found 11 "skill categories" which cover all potential …

The field of Structural Health Monitoring (SHM) has grown significantly over the past few years due to safety and performance enhancing benefits as well as potential life saving capabilities offered by technology. Current advances in SHM systems have lead to a variety of techniques capable of identifying damage. However, few strategies exist for using this information to quickly react to environmental or material conditions needed to repair or protect the system. Rather, current systems simply relay this information to a central processor or human operator who then decides on a course of action, such as altering the mission or scheduling …

Electronic devices are gaining an increasing market share in the medical field. Medical devices are becoming more sophisticated, and encompassing more applications. Unlike consumer electronics, medical devices have far more limitations when it comes to area, power and most importantly reliability. The medical devices industry has recently seen the advantages of using Flash memory instead of Read Only Memory (ROM) for firmware storage, and in some cases to replace Electrically Programmable Read Only Memories (EEPROMs) in medical devices for frequent data storage. There are direct advantages to using Flash memory instead of Read Only Memory, most importantly the fact that …
