About the Cover
The skeletal, phantom-like image of a warship is part of a numerical modeling program
which calculates a ship's electromagnetic response to communications antennas that will be
installed on it. The model displays a ship as a network of tubes with electromagnetic
characteristics modeled as electric current flowing through a wire. Using the computer
model, various trial locations for the antennas can be compared prior to actual
installation, reducing time and expense.
Realistic computer models are taking up where scale models and older, full-scale mockups
leave off in the search for the best site for a shipboard antenna array.
A new, compact telescope makes an observatory of a space shuttle, or even a high-flying
aircraft. The device was used on a recent shuttle mission to observe Comet
Hale-Bopp as it
retreated toward the sun.
- Feeling the Heat
A new, handheld weather station allows accurate measurement of workplace conditions that
can lead to heat stress.
