As WLANs (Wireless Local Area Networks) become increasingly common, it's becoming vital to be able to test them for proper performance and to optimize their operation. This book, written by a member of the IEEE committee that develops WLAN standards, is the first book addressing that need. It covers test equipment and methods for the RF (wireless) and physical layers of WLAN, protocols, the application layer, and manufacturing testing.

CAD is used in the design phase to create plans, test plans and to generate
3D models CAD is used for many purposes from designing towns to
The Nondestructive testing science is a broad field that covers variety of testing methods
and applications, in addition to the associated pre and post processing mathematics. In
terms of methods and techniques the Nondestructive testing modalities rely on different
physical phenomena such as the electromagnetism, the acoustic emission, the thermal
emission and the penetration of high-energy radiation through materials and structures.
The terms “cosmetic tattooing” or “permanent makeup” (e.g. micropigmentation) refer to
mechanical application of pigmented materials to the area of the eye, lips and face for the
purpose of changing the color or appearance of that facial feature. This is a rapidly growing
business in the United States becoming mainstream in many sociological circles.
