Invited Tutorial presented as part of AMS International Short Course Series.

This Tech Talks presentation covers the principles that apply to "good" digital collections and analyzes how objects, metadata, and the user interface together create the users' experience of a collection.

This presentation provides an update on three projects the Texas Digital Library Metadata Working Group (TDL-MWG) is working on. These include designing a metadata information website, creating best practices for images and datasets, and creating metadata courses for Texas Digital Library (TDL) training.

Presentation about ethanol, specifications for E85, and market surveys of fuel quality.

This presentation was given December 14, 2010, as part of DOE's Webinar series. The presentation discusses geothermal heat pump retrofits, technology options, and an overview of geothermal energy and geothermal heat pumps.

This presentation summarizes the approach used to update the U.S. geothermal supply curve.

This presentation discusses a field test of a DHW distribution system in an occupied townhome. It includes measured fixture flows and temperatures, a tested recirculation system, evaluated disaggregation of flow by measured temperatures, Aquacraft Trace Wizard analysis, and comparison.

Presentation for the 2010 University Scholars Day at the University of North Texas discussing research on academic acculturation stress and first generation students.

This presentation discusses The Portal to Texas History and the University of North Texas (UNT) Digital Library collections. It also discusses the invisible internet, other Texas digital collections, other large digital collections, major digital collections in other states, subscription databases, and gives strategies for searching all of these databases.

This presentation discusses the two digital collections in the UNT Libraries, The Portal to Texas History and the Digital Library. It discusses the benefits of these collections, how the partnerships work with organizations who contribute to the collections, and gives examples of the projects and items within these two collections.

This presentation gives an update on the Digital Library and The Portal to Texas History collections held by the University of North Texas (UNT) Libraries in 2010.

Heat removal for power semiconductor devices is critical for robust operation. Because there are different packaging options, different thermal management technologies, and a range of applications, there is a need for a methodology to match cooling technologies and package configurations to target applications. To meet this need, a methodology was developed to compare the sensitivity of cooling technologies on the overall package thermal performance over a range of power semiconductor packaging configurations. The results provide insight into the trade-offs associated with cooling technologies and package configurations. The approach provides a method for comparing new developments in power semiconductor packages and identifying potential thermal control technologies for the package. The results can help users select the appropriate combination of packaging configuration and cooling technology for the desired application.

Presentation on shaded PV power loss, practical issues with modeling shaded PV, and methods of implementing partially shaded PV modeling.

Renewable energy sources, such as wind and solar, have vast potential to reduce dependence on fossil fuels and greenhouse gas emissions in the electric sector. Climate change concerns, state initiatives including renewable portfolio standards, and consumer efforts are resulting in increased deployments of both technologies. Both solar photovoltaics (PV) and wind energy have variable and uncertain (sometimes referred to as "intermittent") output, which are unlike the dispatchable sources used for the majority of electricity generation in the United States. The variability of these sources has led to concerns regarding the reliability of an electric grid that derives a large fraction of its energy from these sources as well as the cost of reliably integrating large amounts of variable generation into the electric grid. In this report, we explore the role of energy storage in the electricity grid, focusing on the effects of large-scale deployment of variable renewable sources (primarily wind and solar energy).
