Interference in narrow-band PLC (Power Line Communication) is discussed in the paper. In power lines, interference greatly affects the attainable data rate and reliability. Communication rate was measured and evaluated for different media, using various facilities with special narrow-band modems for data communication. The spectrum of signals measured for different interference sources is shown...

in this article, the linear array (with 20 elements in the horizontal orientation) of microstrip antenna is examined with horizontal polarization. the set includes three microstrip substrates. there is a power network in two lower substrates and microstrip patches in the upper substrate. excitation of patches has been done as coupled through the power network in two lower substrates. using the ...

This paper aims to explore the boundaries between Media Studies on one hand and Translation other hand. It highlights contact areas these two disciplines sheds light findings insights of both fields, thus informing researchers in their quest develop journalism teaching curricula training courses. A foreign desk editor (FDE) needs cross borders forward backward cultures depending translation fro...

A growing body of research has examined the uptake social media by politicians, formation communication ties in online political networks, and interplay between polarization. However, few studies have analyzed how are affecting parliamentary networks. This is especially relevant highly fragmented systems which collaboration parties crucial to win support parliament. Does MPs’ use foster communi...

The paper applies concepts of population dynamics to the evolution of communication technologies. The dynamics of voice communication technologies in the Czech and Slovak Republics in 1948-2009 are examined via the Lotka-Volterra equations. Fixed lines and mobile phones are considered predatory technologies hunting for their ‘prey’ – voice service subscribers. Each technology squeezes out carry...
