Item Building Information Modeling - A Minimum Mathematical Configuration(2012-10-19) Bhandare, RuchikaIn the current context, the standardization of building construction is not limited to a specific country or to a specific building code. Trade globalization has emphasized the need for standardization in the process of exchange of design information, whether it is in the form of drawings or documents. Building Information Modeling is the latest transformational technology that supports interactive development of design information for buildings. No single Building Information Modeling software package is used in the Architecture Engineering Construction and Facilities Management industries, which is strength as new ideas develop, but a hindrance as the new ideas flow at a different pace into the various programs. The standards divergence of various software results in a limited ability to exchange data between and within projects, especially one sees the difficulty in moving data from one program to another. The Document eXchange File format represents an early attempt to standardize the exchange of drawing information by Autodesk. However, the data was limited to geometric data required for the production of plotted drawings. Metadata in a Building Information Model provides a method to add information to the basic geometric configuration provided in a Document eXchange File. Building Information Model programs use data structures to define smart objects that encapsulate building data in a searchable and robust format. Due to the complexity of building designs eXtensible Markup Language schemas of three dimensional models are often large files that can contain considerable amounts of superfluous information. The aim of this research is to exclude all the superfluous information from the design information and determine the absolute minimum information required to execute the construction of a project. A plain concrete beam element was used as the case study for this research. The results show that a minimal information schema can be developed for a simple building element. Further research is required on more complex elements.Item Designing a Griotte for the Global Village: Increasing the Evidentiary Value of Oral Histories for Use in Digital Libraries(2011-10-21) Dunn, Rhonda ThayerA griotte in West African culture is a female professional storyteller, responsible for preserving a tribe's history and genealogy by relaying its folklore in oral and musical recitations. Similarly, Griotte is an interdisciplinary project that seeks to foster collaboration between tradition bearers, subject experts, and computer specialists in an effort to build high quality digital oral history collections. To accomplish this objective, this project preserves the primary strength of oral history, namely its ability to disclose "our" intangible culture, and addresses its primary criticism, namely its dubious reliability due to reliance on human memory and integrity. For a theoretical foundation and a systematic model, William Moss's work on the evidentiary value of historical sources is employed. Using his work as a conceptual framework, along with Semantic Web technologies (e.g. Topic Maps and ontologies), a demonstrator system is developed to provide digital oral history tools to a "sample" of the target audience(s). This demonstrator system is evaluated via two methods: 1) a case study conducted to employ the system in the actual building of a digital oral history collection (this step also created sample data for the following assessment), and 2) a survey which involved a task-based evaluation of the demonstrator system. The results of the survey indicate that integrating oral histories with documentary evidence increases the evidentiary value of oral histories. Furthermore, the results imply that individuals are more likely to use oral histories in their work if their evidentiary value is increased. The contributions of this research ? primarily in the area of organizing metadata on the World Wide Web ? and considerations for future research are also provided.Item Incorporating voltage security into the planning, operation and monitoring of restructured electric energy markets(Texas A&M University, 2006-04-12) Nair, Nirmal-KumarAs open access market principles are applied to power systems, significant changes are happening in their planning, operation and control. In the emerging marketplace, systems are operating under higher loading conditions as markets focus greater attention to operating costs than stability and security margins. Since operating stability is a basic requirement for any power system, there is need for newer tools to ensure stability and security margins being strictly enforced in the competitive marketplace. This dissertation investigates issues associated with incorporating voltage security into the unbundled operating environment of electricity markets. It includes addressing voltage security in the monitoring, operational and planning horizons of restructured power system. This dissertation presents a new decomposition procedure to estimate voltage security usage by transactions. The procedure follows physical law and uses an index that can be monitored knowing the state of the system. The expression derived is based on composite market coordination models that have both PoolCo and OpCo transactions, in a shared stressed transmission grid. Our procedure is able to equitably distinguish the impacts of individual transactions on voltage stability, at load buses, in a simple and fast manner. This dissertation formulates a new voltage stability constrained optimal power flow (VSCOPF) using a simple voltage security index. In modern planning, composite power system reliability analysis that encompasses both adequacy and security issues is being developed. We have illustrated the applicability of our VSCOPF into composite reliability analysis. This dissertation also delves into the various applications of voltage security index. Increasingly, FACT devices are being used in restructured markets to mitigate a variety of operational problems. Their control effects on voltage security would be demonstrated using our VSCOPF procedure. Further, this dissertation investigates the application of steady state voltage stability index to detect potential dynamic voltage collapse. Finally, this dissertation examines developments in representation, standardization, communication and exchange of power system data. Power system data is the key input to all analytical engines for system operation, monitoring and control. Data exchange and dissemination could impact voltage security evaluation and therefore needs to be critically examined.Item Texas Archival Resources Online: A Community-Driven Redesign(2016-05-25) Bowman, Amy; Grinstead, Leigh; University of Texas at Austin; LYRASISMembers of the Texas Archival Resources Online (TARO) Steering Committee will report on the past year's work to plan significant improvements to Texas' one and only consortial website for archival finding aids, under the NEH 21st Century Collaborative Planning Grant. Topics will include governance and organizational home explorations, system platform research and testing, usability testing, education and outreach, standards, and more. The TARO website was created with grant funding more than 16 years ago with ongoing hosting and maintenance generously provided by UT Libraries. However, with close to 1 million visits per year, it is past time to reimage TARO - both in terms of 1) how users interact with collection data currently provided in EAD and 2) how TARO community members might design a system of continued support that will enable archivists, librarians, and museum curators to respond to changing user expectations, professional standards, and technologies. Join us for a quick moving session to learn more about TARO in the 21st Century.
