OT - based on the names of scientists/engineers in the reference mentioned, I realized that they are somewhere from former YU (Croatia, Serbia, Bosnia). It is pain for me to look how many educated people with good knowledge/projects (see for example "Arta" program in "Measurements Systems and Techniques" section) exist here...and how much they are underestimated and balked and little payed... The only way to actually make something is to go somewhere else.
