Semiactive Damping of Cables with Sag [.pdf]
http://www.usc.edu/dept/civil_eng/johnsone/papers/smartdamping_sagcable.html
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 flexibility," a series of equations are derived that govern the motion of the cable. These are then used to show the effectiveness of semiactive dampers in reducing vibration. [CL]

Protecting Applications against Malice Using Adaptive Middleware [.pdf]
http://www.dist-systems.bbn.com/papers/2002/IFIPCSES/IFIPCSES.pdf
Security in distributed computing systems is a very important area of research, especially as malicious behavior is a growing cause of concern for businesses and organizations. This paper addresses an emerging method of maintaining security in untrustworthy environments. Until recently, the operating system was the only means of protecting data; the authors discuss a more elaborate technique of using middleware as a second level of security. "When integrated effectively, this multi-level approach makes it harder for intruders to corrupt or disable distributed systems and applications." The paper is scheduled to appear in 2003; several other papers on related topics can be found on the site's home page. [CL]

Chaos Lab: An Orderly Pursuit of Disorder [.zip]
http://www.livinggraphs.com/enu/products/cl/
Chaos Lab is a great piece of software that teaches users about fractals and chaos theory. The menu-driven interface is extremely easy to use; however, a significant drawback of the software is its poor documentation. This can make experimenting with the settings more fun, but it would be helpful to have better explanations of the more obscure functions. What Chaos Lab lacks in documentation, it makes up for in the remarkable visual representations of famous fractals. The Mandelbrot and Julia sets can be explored with simple zooming tools, equation definitions, and brilliant color selections. Many more options are available, making the program a powerful educational tool in a small package. It is a free download. [CL]

8. 2002 News Releases: How to Sort Science Fact from Science Fiction [RealPlayer]
http://www.jpl.nasa.gov/releases/2002/release_2002_207.cfm
With the recent release of the new James Bond film, it seems appropriate to consider the technology used so creatively on the silver screen. Movies often show elaborate gadgets that seem physically impossible, but they also can inspire the creation of real-life devices.
An excellent example of science fiction turned science fact is the Star Trek communicator. It is virtually identical in function to today's cellular phones, but it was envisioned nearly 30 years before it became a common accessory. Many other parallels of Star Trek concepts to everyday life are illustrated in a short article from the winter 2002 Albright College newsletter (1). Researchers at the Australian National University have accomplished a feat that also originated with Star Trek. The team demonstrated the transportation of a beam of light. A BBC news report (2) describes the specifics of the research, and also includes a separate section that ponders whether human transportation will ever be possible. Several of James Bond's gadgets are highlighted at this Web site (3). A few opposing viewpoints are provided, which contrast real spy devices to the ones used by 007. At a trade show held in June 2002, an industry representative suggested that companies should use Bond-like tactics to help in the war on terrorism (4). This could take the form of technology development, and the cooperation between government and corporations was encouraged in the speech amusingly titled "James Bond Saves the USA." A discussion about technology from Bond movies would not be complete without a look at the real-life counterparts of the films' spy devices. The International Spy Museum (5) has a large collection of items from the CIA, KGB, and elsewhere. Some of the amazing gadgets described on this site include a lipstick pistol, a poison gas gun, and a coat with a buttonhole camera. An interesting essay about futuristic visions in science fiction movies is given at this site (6). It traces examples all the way back to the 1903 film A Trip to the Moon. A collection of lesson plans for different grade levels is presented by the NASA Explores program (7). The activities encourage students to think about science fiction's effect on their lives, and how devices once limited to the imagination have become reality. Another resource, provided through NASA's Jet Propulsion Laboratory, is a pair of lectures given in November 2002. They address topics of space exploration, intelligent robots, and how recent advances in these areas compare to science fiction. This site (8) contains the news release about the lectures, while giving a link to the archive where the Web casts can be viewed. [CL]
