Military equipment often requires significant amounts of electrical power, and it is important for power supplies to be portable and to have large capacities. The Defense Advanced Research Projects Agency realizes this need for efficient power sources, so it is investigating alternatives to conventional batteries. High energy fuels are the primary focus of the Palm Power project. This Web site discusses the details and goals of the project in introductory sections. More specific information can
Engineer's Edge: Solutions by Design
Engineer's Edge is a great reference for a wide variety of engineering, design, and manufacturing information. Most of the material is in the form of online calculators and equation charts, which save users time that would otherwise be spent flipping through books. Other resources such as part specifications (e.g., drill sizes, gauge charts) and material properties are also available. Interactive conversion tools, beam statics analyzers, and calculators for many different applications are free a
Clean Coal Technology Compendium
Operated by the National Energy Technology Laboratory, the Clean Coal Technology (CCT) Program works with new coal burning methods of energy generation that minimize environmental impact. The material on this Web site outlines some of the findings of the CCT program. Most of the information is contained in the topical reports, which deal with environmental control technologies, advanced electric power generation, coal processing for clean fuels, industrial applications, and other general topics.
The Planetary Geology Group at Arizona State University developed this online activity to teach elementary and middle school students "the stratigraphy (layers) of lava flows produced by multiple eruptions" on the moon. The first part of the website provides teachers with background information about the layers of basaltic lava flows that cover about sixteen percent of the Moon as well as how to prepare for the activity and what to expect. Visitors can use the second part of the website as an in
incits: Technical Committee T10
This organization's Web site is a repository of information about computer input/ output (I/O) interfaces. The T10 Technical Committee works to oversee the development of voluntary standards for low-level interfaces, specifically "the Small Computer System Interface (SCSI)." A large collection of these standards and related technical reports is provided on this site. Many variations of SCSI are documented, as well as other interfaces, such as IEEE 1394 and fibre channel. The standards cover arch
Pharmacist.com is an information resource project developed jointly by the National Association of Boards of Pharmacy and the American Pharmacists Association. The website is designed to support pharmacists, pharmacy technicians, and pharmacy students by providing useful information and professional development resources. Professionals seeking employment will certainly appreciate the extensive job board with hundreds of listings from around the country. The site also contains a sizeable collecti
National Pollutant Release Inventory
The National Pollutant Release Inventory is maintained by Environment Canada and provides access to pollutant release information for facilities located throughout Canada. The data can be searched by chemical name and location, and results provide detailed information on the substance, its release, its disposal, and its transfer at a particular facility.
The Turing Test
A man before his time, Alan Mathison Turing is arguably one of the most recognized mathematicians of the 20th century. In 1950, he published a paper that, to this day, sets the standard for artificial intelligence. He proposed a way to determine if a machine has intelligence, and this is now called the Turing Test.In his 41-year life, Turing accomplished a great deal as a mathematician. Bordering on many philosophical issues, his work is recounted in this online biography (1). A very good introd
What is Climate Change?
This site is offered by Canada's Natural Resources Department. The main page describes the basics of the phenomenon, while the links tell about the impact of climate change on health and safety, communities, land resources, water resources, and coastal regions. Although specific to Canadian regions, the site will give visitors from all over a good introduction to the potential problems of global warming.
Orchids of Wisconsin: An Interactive Flora
Orchid enthusiasts may appreciate this Web site developed by Jeff Hapeman, graduate student at the University of Wisconsin-Madison. Information including "photos, typical taxonomic descriptive information, a description of similar species to aid in identification, habitat information, blooming dates, a section on pollination biology (if information is available), herbarium records, and a range map" are included for each species of orchid (native and naturalized) found in Wisconsin.

Integrating Content Management with Digital Rights Management
This white paper, published in May 2003, explores the task of effectively managing digital content while incorporating and protecting the digital rights associated with the content. The authors begin by defining a content management system as it is discussed in their paper and outline the key components and capabilities of such a system. After touching on the foundations of digital rights, the paper then argues for the adoption of a "Rights Expression Language" to integrate digital rights inform
