The Formal and the Informal in the History of Socialist Scholarly Interconnectedness in East Central Europe.
NTM
June 2024
The Tadeusz Manteuffel Institute of History, Polish Academy of Sciences, Warsaw, Poland.
With the emergence of Olympic internationalism, scholarly networking in East Central Europe came to be dominated by the idea of scholars representing their nations, which replaced the previously leading pattern of private elite scholars with extensive international contacts. This also formalised trans-border contacts, which became increasingly seen as international. In this article, we trace the relationship between these formal and informal networks from the late 19th century to the end of the socialist period, showing that even as formalisation grew, it depended heavily on a variety of informal connections.

IEEE Trans Ultrason Ferroelectr Freq Control
October 2012
Inst. of Radio Eng. and Electron., Czechoslovak Acad. of Sci., Prague.
Direct digital frequency synthesizers (DDS or DDFS) are widely used in modern communications and measurement devices. Their advantages are small size and power consumption together with excellent frequency stability, high frequency resolution, and short switching times. The difficulties are rather low output frequencies (500 MHz at the present state of the art) and a large set of the spurious signals very often above the -80 dB level.
