CASCADE: Computer aided synchronization of code and documentation

Complete, accurate and up-to-date documentation is a critical factor in the development and maintenance of robust software products. Often, however, the documentation and the product diverge over time, leading to inconsistencies that are the source of confusion and faults, which can lead to failure. This thesis addresses the inconsistency problem by describing a standard method for the synchronization of documentation with code. As part of the thesis, existing research in the field of Document Engineering is surveyed and related to the method being developed. One goal of this approach is to create straightforward integration with existing languages, coding styles, and documentation formats. In particular, the method supports integration into existing development tools and software processes. As a proof of concept, an implementation of the CASCADE system has been developed. The HTML documentation and the Java source code for the system itself is used as an example to demonstrate the capabilities of CASCADE. Hypothetical changes to the code and documentation are analyzed both with and without the use of the synchronization method. The prototype system has been found to enhance source code and documentation navigation considerably

Ultrasonic evaluation of oxidation and reduction effects on the elastic behavior and global microstructure of YBa2Cu3O7-x

Ultrasonic velocity measurement techniques were used to evaluate the effects of oxidation and reduction on the elastic properties, global microstructure and oxygen content of the YBa2Cu3O(7-x) ceramic superconductor for samples ranging from 70 to 90 pct. of theoretical density. Bulk density, velocity, and elastic modulus generally increased with increasing oxygen content upon oxidation, and this behavior was reversible. Velocity image patterns were similar after oxidation and reduction treatments for a 90 pct. dense sample, although the velocity value at any given point on the sample was changed following the treatments. The unchanging pattern correlated with destructive measurements showing that the spatial pore distribution (fraction and size) was not measurably altered after the treatments. Changes in superconducting behavior, crystal structure, and grain structure were observed consistent with changes in oxygen content

Oral History Collections at James Madison University: Defining Digital Workflows

Oral History collections present challenges surrounding legacy media formats, born digital and digitized content, transcription, preservation, and user access. Collections might contain a variety of analog and digital materials which need to be considered holistically for processing and organization, preservation, and access. In this presentation, librarians from James Madison University discuss collaborating to improve workflows for processing oral history collections held in JMU Libraries\u27 Special Collections
