    The use of compressed-air energy storage (CAES), in which off-peak electricity is used to compress air and store it in a cavern underground, is described. To supply electricity during peak load, the compressed air is released to a combuster where it mixes with oil or gas. The operation of the 110-MW McIntosh plant of the Alabama Electric Cooperative is explained. The fact that three-fourths of the... View full abstract»

    The author examines the controversy over the effects of human exposure to electromagnetic fields, particularly the magnetic field at power line-frequencies (60 Hz in North America, 50 Hz in Europe and some other places). She discusses typical exposures and describes some epidemiological studies and laboratory experiments. It is pointed out that, overall, the existing evidence is not convincing tha...

    The characteristics of spread-spectrum systems that account for their growing use are examined. They offer low probability of intercept, signal hiding, and jammer rejection. Spread spectrum also provides a measure of immunity to multipath interference and multiple access capability, making it ideal for radar, telephone, local area networks, and many other applications. The two primary techniques c... View full abstract»

    Asynchronous transfer mode (ATM), selected for broadband integrated services digital networks and receiving much standardization activity, is discussed. ATM is a packet switching technique with minimal functionality in the network and hence is often called fast packet switching. In transmission, statistical multiplexing replaces the time-division multiplexing of the synchronous transfer mode. The ... View full abstract»

    A description is given of the IRIDIUM communication system, so-called because the system design originally consisted of 77 networked satellites, and the element iridium has the atomic number 77. The goal is to make instant global communications a reality. The system design now consists of 60 satellites, a system control facility, gateways, and subscriber units. Each of these components is examined... View full abstract»
