Autonomous control in logistics lets each logistic object take its own decisions and thus leads to a shift from central planning in advance to production control in real time. This paper presents the results of a comparison of

This can lead to serious cost reduction, both for the manufacturers and the users of magnetron ...

This paper presents some results of the planetary boundary layer (PBL) and upper troposphere characteristics, obtained from the combined lidar-ceilometer-sunphotometer, aerosol particle counter and meteorological measurements made over Sofia (urban area, park zone and mountain). The main aim is deter-mination of optical and microphysical characteristics of the atmospheric aerosol in three points of the valley and their variation during the planetary boundary layer formation over urban area, park zone and mountain and interaction with free atmosphere. It merits special mention that new instruments were used for the first time in Bulgaria during this complex experiment. First of all, the inclusion of ceilometer CHM 15k constitutes a novel component. It enables observation of the aerosol structure of the atmosphere up to the trop...
