Privatization and Self-Regulation as Tropes of Global Media Restructuring There is a power to language itself in affecting media reform around the world. The field of media regulation is filled with examples of strong ideas, encapsulated in words and phrases, that have an enormous impact on legislative transformation, and the export of which seems a characteristic of globalization. Just think of the ideology-laden tropes

HIGH RESOLUTION SIGNAL CONDITIONING ADCs Walt Kester, James Bryant, Joe Buxton The trend in ADCs and DACs is toward higher speeds and higher resolutions at reduced power levels. Modern data converters generally operate

Spacecraft data processing requires microcomputers and interfaces that are functionally similar to desktop systems However, space systems require: Low power, volume, and mass High reliability and fault tolerance

For a given mass flow m ind thrust F, we would like to minimize the running power
