Welcome to the World's Longest Tunnel Page
This Web site contains information on hundreds of the world's longest tunnels. There are four main categories that list facts about road, subsea, railway, and canal tunnels. Each of these sections can be browsed in its entirety or separated into individual countries. The data is presented in tables and includes years of construction, length, depth, and gradient. Future projects are also shown, and many of the tunnels have links to sites with further information. A problem with the site is that n
Computer Graphics & Digital Animation
Computer graphics is a term that encompasses a wide range of sciences and techniques. To understand some of the processes involved in generating computer graphics, Cornell University offers this detailed introduction to the subject (1). The site contains explanations and a series of pictures that illustrate object rendering, shading, ray tracing, and more. Computer graphics has seen rapid advancements in the past few years, partly because of the development of dedicated graphics processing units
MIT Media Lab: Software Agents [pdf, Microsoft Word, QuickTime, Macromedia Flash Player,
The Software Agents Group of the MIT Media Laboratory "investigates computer systems to which one can delegate tasks." Software agents are different from conventional software because they are "long-lived, semi-autonomous, proactive, and adaptive." Software Agents Group focuses on creating software that "acts as an assistant to the user rather than a tool, learning from interaction and proactively anticipating the user's needs." The website describes their various projects that use "commonsense

The site includes a small image gallery, an extensive reference section on the subject, and relevant links to other freshwater jellyfish research Web sites. The authors
"Just the Maths"
Developed by a retired mathematics professor from Coventry University, this website "is a collection of separate units, in chronological topic-order, intended to service foundation level and first year degree level courses in higher education, especially those delivered in a modular style." Although there are separate sections for students and teachers, both contain essentially the same information except for the format of the material -- printable pages with slightly more detailed explanations
Using Geographic Information Systems to Map Crime Victim Services
The US Department of Justice released this document in February 2003 about the use of geographic information systems (GIS) in law enforcement. "GIS is an application that links database software to graphics software to create visual images of various types of data in map format." The report outlines the applications of such systems in police cars and at victim assistance facilities, providing examples of situations where it has been used successfully and cases that could have benefited from GIS.
