Semiactive Damping of Cables with Sag
Vibrations in support cables can be caused by wind, rain, or other forces acting on the attached structure. This can result in premature failure of the cable or its connections, thereby reducing the cable's useful lifetime. This research paper, from the University of Southern California civil engineering department, extends the previous work of the authors on smart vibration damping techniques. Through accurate modeling of the cable and including the properties of "sag, inclination, and axial fl

"A collective effort between the Jane Goodall Institute, zoological facilities, and universities," ChimpanZoo is a research and education program that aims to "apply uniform research methods to learn more about chimpanzees and their psychological and behavioral responses to a captive environment." The program involves participating zoos, researchers, and volunteers collecting and submitting chimpanzee behavior data to the program. The site contains a great deal of information on chimpanzee behav
USGS: National Geochemical Survey Database
The USGS's National Geochemical Survey (NGS) is producing "a body of geochemical data for the United States based primarily on stream sediments, analyzed using a consistent set of methods." After learning the history and background of the project, users can access the NGS data by geographic area. The website allows researchers to compare the analytical methods and view national maps illustrating the distribution of these methods for each element. Visitors can easily view maps of the distribution
Soap and Bubbles
The first Web site, from The Soap and Detergent Association, is called Soaps and Detergents (1). Visitors learn about the chemistry of soap and detergent, their history, how they're manufactured, and more. The easily read text and fun illustrations make this site a great place to start for this topic. The next site, called Bubble Engineering (2), is provided by Bubble Town. The page describes the physics of a cone-shaped bubble blowing device and how its shape reduces the velocity of air being b
Civil Engineering is a monthly publication of the American Society of Civil Engineers. Although full access to the magazine is reserved for subscribers, each month's feature story is provided free on this Web site. These in-depth articles examine some of the most outstanding spectacles in the world of architecture and construction. Feature stories dating back over a year are archived and can still be viewed.
Amazing Earth Games: Disasters You Can Play at Home
Another above average offering from Discovery.com, the Amazing Earth Games: Disasters You Can Play at Home Web site does a great job at making learning fun. The interactive activities include: Crumble California, in which users get to see how the continental plates have affected the state; Unleash a Superstorm, which lets you create your very own hurricane; and the Destroy Life on Earth activity, which gives you the power to launch fireballs at our planet and witness the result.
