The main aim of the research has been to characterise changes the urban functional areas in Poland over 2002–2017 period. The research was based on J.W. Webb’s population development types method enabling to identify links between natural growth and the migration net. A wider analysis concerned components of real increase which, through feedback, influenced level and population dynamics in these areas. Results of the study showed the diversity of demographic processes within Polish urban functional areas as well as in their cores, which will shape different processes in those areas in the future.

Self-government districts in the minds of the city residents on the example of selected districts of Cracow, The article demonstrates the problem of perception of auxiliary units of the city by its residents. The history of the creation of self-government districts in Cracow was presented, the results of the survey conducted among the residents of three districts were shown (n=1433) and they were referred to the observations of other authors outlined in the subject literature. The study revealed that the self-government districts, which have been functioning for more than a quarter of a century, are poorly embedded in the consciousness of residents and do not play a significant role in their lives. Most of the respondents were not able to give the name of their own district correctly and did not know its spatial extent. The former administrative divisions and historical settlement units (former villages) were still deeply rooted in their consciousness. Most of the respondents did not take part in public life of the districts, nor did they participate in the initiatives taken at their level.

The Cracow districts have the status of auxiliary self-governing units within this city and, generally should be communities of residents living in particular parts of the city, close to them, in which they implement their daily practices. In theer article, the authors, by examining the sense of belonging to the district, undertook to identify its perception by residents and relations between the residents and their auxiliary units, on the example of two such districts this of VIII Dębniki and X Swoszowice. Attitudes of their residents towards self-governing districts were identified on the basis of 1141 questionnaires, obtaining during surveys conducted in 2017. The authors have found relatively weak relations of residents with their auxiliary units, as evidenced by small involvement in initiatives taken for the benefit of this districts. The analysis, however, showed also considerable differences in the detailed assessment of the attitudes of residents at the level of their division according to their age groups, period of the residence, as well as to the type of housing a single-family, multi-family or mixed ones.

This paper describes a synthetic aperture radar system for tactical-level imagery intelligence installed on board an unmanned aerial vehicle. Selected results of its tests are provided. The system contains interchange-able S-band and Ku-band linear frequency-modulated, continuous wave radar sensors that were built within a frame of a research project named WATSAR, conducted by the Military University of Technology and WB Electronics S.A. One of several algorithms of radar image synthesis, implemented in the scope of the project, is described in this paper. The WATSAR system can create online and off-line radar images.
