This presentation discusses My InfoQuest, a service that lets you text a question to a librarian and receive a quick response on your mobile device.

This presentation presents information about The Portal to Texas History, a digital gateway to cultural heritage collections in Texas. This presentation discusses the IOGENE project, the research processes involved in developing The Portal to Texas History, the research with genealogists, and shows illustrations of the contents of The Portal to Texas History.

The US has a national set of codes and standards that address the use of hydrogen technologies. These documents are published by several organizations and are not all directly adopted by government authorities. The US Department of Energy (DOE) has acted as the central organizing group to identify these documents and present them as a coherent and integrated set of requirements.

The data analysis objectives are: (1) Independent assessment of technology, focused on fuel cell system and hydrogen infrastructure:performance, operation, and safety; (2) Leverage data processing and analysis capabilities from the fuel cell vehicle Learning Demonstration project and DoD Forklift Demo; (3) Establish a baseline of real-world fuel cell operation and maintenance data and identify technical/market barriers; (4) Support market growth of fuel cell technologies by reporting on technology features relevant to the business case; and (5) Report on technology to fuel cell and hydrogen communities and stakeholders.

Stabilization/preconditioning promise stable performance. CV-derived depletion width changes & hysteresis appear linked to stability; dark exposure in forward bias emulates light exposure at 1-sun.

Presentation about the importance of continued progress toward low-cost, high-reliability, and high-performance PV systems. High reliability is an essential element in achieving low-cost solar electricity.

This presentation attempts to answer the research question: "What percentage of parents do their children's science fair projects for them?" It also discusses about selection tools for finding useful science books.

In the United States, concentrating solar power (CSP) is one of the most promising renewable energy (RE) technologies for reduction of electric sector greenhouse gas (GHG) emissions and for rapid capacity expansion. It is also one of the most price-competitive RE technologies, thanks in large measure to decades of field experience and consistent improvements in design. One of the key design features that makes CSP more attractive than many other RE technologies, like solar photovoltaics and wind, is the potential for including relatively low-cost and efficient thermal energy storage (TES), which can smooth the daily fluctuation of electricity production and extend its duration into the evening peak hours or longer. Because operational environmental burdens are typically small for RE technologies, life cycle assessment (LCA) is recognized as the most appropriate analytical approach for determining their environmental impacts of these technologies, including CSP. An LCA accounts for impacts from all stages in the development, operation, and decommissioning of a CSP plant, including such upstream stages as the extraction of raw materials used in system components, manufacturing of those components, and construction of the plant. The National Renewable Energy Laboratory (NREL) is undertaking an LCA of modern CSP plants, starting with those …

This presentation discusses the costs and values of digital collections. It looks at the digital collections held at the University of North Texas (UNT) and does a cost comparison of the options based on their choices including the expenses that are related to building their digital collections.

Presentation for the 2009 Society for the Preservation of Natural History Collections Meeting. This presentation discusses research on high-throughput workflow for computer-assisted human parsing of biological specimen label data. This is part of the Apiary Project, a collaboration of the Texas Center for Digital Knowledge at the University of North Texas and the Botanical Research Institute of Texas.

Presentation on NREL's integrated biomass conversion capabilities. Presented at the 2009 Advanced Biofuels Workshop in Denver, CO, Cellulosic Ethanol session.

This presentation addresses "Calf-Path" problems for Electronic Theses and Dissertation (ETD) repositories, problems associated with the early ad hoc and idiosyncratic workflow patterns. This presentation also documents relatively simple principles and guidelines for such ETD programs that can greatly improve the subsequent likelihood of implementing successful distributed digital preservation programs.

The conclusions from this report are: (1) hydrogen has several important advantages over competing technologies, including - very high storage energy density (170 kWh/m{sup 3} vs. 2.4 for CAES and 0.7 for pumped hydro) which allows for potential economic viability of above-ground storage and relatively low environmental impact in comparison with other technologies; and (2) the major disadvantage of hydrogen energy storage is cost but research and deployment of electrolyzers and fuel cells may reduce cost significantly.

NREL worked with GM and demonstrated equivalent performance in the Saturn Vue Belt Alternator Starter (BAS) hybrid vehicle whether running with its stock batteries or a retrofit ultracapacitor system.

Battery cost, calendar life, and cycle life are three important challenges for those commercializing plug-in hybrid electric vehicles; battery life is sensitive to temperature and solar loading.

This presentation outlines NREL's multi-physics simulation study to characterize an internal short by linking and integrating electrochemical cell, electro-thermal, and abuse reaction kinetics models.

This presentation discusses the University of North Texas Libraries' strategies for creating digital collections and services from datasets and born digital objects and serving users outside of formal education and research.

This presentation discusses the University of North Texas (UNT) Libraries' Digital Projects Unit and how the system and software to create digital collections was developed. It also discusses the future plans for system and software changes in the Digital Projects Unit.
