Aerospace & Ocean Engineering: AOE Resources

The NTRS integrates NASA's following three collections and enables search and retrieval through a common interface:

NACA Collection: Citations and reports from the National Advisory Committee for Aeronautics period lasting from 1916 to 1958.
NASA Collection: Citations and documents created or sponsored by NASA starting in 1958 and continuing to the present.
NIX Collection: Citations and images, photos, movies, and videos are downloaded from the NASA Image eXchange and served out through NTRS. NIX is a separate system and users can also go directly to the NIX site to search imagery.

Citations in the NTRS indicate if an item is available online or if it should be ordered. If the item is available from NASA, the citation will provide guidance on ordering items from the NASA Center for AeroSpace Information. If the item is not available from NASA, the citation provides a link to a list of suggested sources from which to order the document.

Online access is free for .gov, .edu, .mil, .k12, .us and other selected domains and many products listed here are free for all users. See the Free Access section of the NCDC Help page for detailed information.
Period of record shown indicates period of data available online. The period of record for the complete data set may vary and is dependent on the desired location. Data prior to the period of record indicated may be available. The NCDC archives contain data as far back as the 1800s for certain data typesand locations. Contact the NCDC for availability, pricing and ordering information.
Any data product ordered from NCDC may be certified for court, but only the more commonly certified products can be certified for court online. For ordering certified copies of items where certifications are not offered online, please contact the NCDC. For more information, please see the note on certifications on our NCDC Ordering page.
Online means available through our web site for electronic delivery, although some items ordered online may require online delivery by mail and those are subject to a service charge. Some orders could be subject to a consultation fee or handling charge.
Offline means the data type is not available through our web site. Contact the NCDC for availability, pricing and ordering information. Many items cost more when ordered offline.
Some products require Adobe Acrobat Reader.

The analysis and study of engineering failures is an essential part of many engineering curricula today. This focus enables modern engineers and scholars to learn what not to do and how to create designs with a greater chance of success. Yet the tools to teach these classes are often inconsistent, with much of the material scattered across numerous resources. Once located, information can be subjective and incomplete.
The engineering field needs a comprehensive resource to provide in-depth, impartial analysis of key engineering failures. Engineering Case Studies Online is an online collection that offers 250 hours of video and 50,000 pages of text resources to meet this growing need. It provides in-depth coverage for 50 of the most frequently taught and seminal case studies around the world together with supplementary materials from more than 1,000 additional failures.

MathWorld has been assembled over more than a decade by Eric W. Weisstein with assistance from thousands of contributors. Since its contents first appeared online in 1995, MathWorld has emerged as a nexus of mathematical information in both the mathematics and educational communities. It not only reaches millions of readers from all continents of the globe, but also serves as a clearinghouse for new mathematical discoveries that are routinely contributed by researchers. Its entries are extensively referenced in journals and books spanning all educational levels, including those read by researchers, elementary school students and teachers, engineers, and hobbyists.

MathWorld continues to grow and evolve with the assistance of thousands of contributors. Careful oversight of all aspects of its content and interface by creator Eric Weisstein, and more recently with able assistance from MathWorld associate Ed Pegg, Jr., provides an exacting level of quality, accuracy, and consistency. As a result, MathWorld is considered not only the clearest and most readable online resource for mathematics, but also one of the most reliable.

MathWorld is actively developed and maintained. The site is updated daily, thus achieving extremely rapid communication of new and extended results--many of which are provided by outside contributors--while at the same time maintaining a degree of editorial oversight and consistency across (and among) the site's nearly 13,000 entries that is simply not possible for other sites.

MathWorld currently features a number of innovative interactive elements that enhance its usability for a variety of different readers. These features include:

The MathWorld Classroom, which provides a set of pop-up "capsule summaries" for more than 300 mathematical terms.
Extensive citations to books and journal articles, many of which are active hyperlinks (but no Get VText links or cues).
Thousands of downloadable Mathematica notebooks.
Several types of interactive entries, including LiveGraphics3D applets for interactive three-dimensional geometry.
A powerful full-text search engine with both basic and advanced searching capabilities.
Dublin Core and Mathematics Subject Classification metadata in the HTML headers of each page.
Special information for Mathematica users.

The technology behind MathWorld is heavily based on Mathematica. In addition to being indispensable in the derivation, validation, and visualization of MathWorld's content, Mathematica is used to build the website itself, taking advantage of its advanced mathematical typesetting and data-processing capabilities.

Factiva provides full-text news articles and business information. From the Search tab, use the Free Text search box to explore an archive of over 50 years of news and other sources.

From the News Pages tab, you can browse current issues of major newspapers and business magazines from around the world.

From the Companies/Markets tab, you can research competitors, suppliers, customers, and partners through market data, interactive charts, financial statements, and more for individual companies or industries. Data includes current and historical pricing on a variety of financial instruments like stocks, funds, currencies, and market indexes.

IBISWorld provides a comprehensive collection of industry market research reports. Industry Research Reports are powerful business tools that provide strategic insight and analysis on over 700 U.S. industries. Each industry report is written at the 5-digit NAICS level - an unparalleled degree of detail. The reports are updated frequently, which gives you the confidence to make accurate and speedy business decisions.
Each report includes 9 chapters, and 34 sub-chapters that provide insight into current and forecast industry performance, changing trends, operating conditions and supply chain linkages.

Every industry faces a set of variables outside its control that have a material effect on industry performance. These factors, which include exchange rates, commodity prices, consumer attitudes, weather conditions, government policies among others are covered by our extensive range of business environment reports. Understanding these factors makes it easier to predict trends for your business and competitors.

So, what are the key factors outside the control of your organisation that determine the performance of your industry? Find out in our brief summaries within our industry research reports, or use our business environment reports as a supplement to acquire a deeper understanding of these trends. Our two-to-three-page business environment reports provide insights into all the demographic, environmental and business trends that you can’t afford to ignore.
