There are international organizations for preparation variety of standards. In ISO organization TC 211 group elaborates standards for geographic information system creation. Its works are observed by national working groups interested in those topics. European normalization committee CENffC 287 worked about it too. Basing on international standards Polish Standard Committee (PKN) has undertaken works on applicable schemes to standardize notion scheme for data of geographic. In this paper critical opinion of geometric description of geographic data in space scheme spread by PKN on chosen elements of data modelling is presented. It is illustrated by chosen examples of data modeling.

In this work, a novel approach to designing an on-line tracking controller for a nonholonomic wheeled mobile robot (WMR) is presented. The controller consists of nonlinear neural feedback compensator, PD control law and supervisory element, which assure stability of the system. Neural network for feedback compensation is learned through approximate dynamic programming (ADP). To obtain stability in the learning phase and robustness in face of disturbances, an additional control signal derived from Lyapunov stability theorem based on the variable structure systems theory is provided. Verification of the proposed control algorithm was realized on a wheeled mobile robot Pioneer–2DX, and confirmed the assumed behavior of the control system.

This article is an attempt to confront the autothematic refl ection in Leopold Staff’s (Ars poetica and The Artist’s Sadness) with two poems, inspired by a somewhat similar approach, by Tymoteusz Karpowicz and Krystyna Miłobędzka. What they seem to have in common are textual signs of welcome with ‘open arms’ and ‘the outstretched hand’. These emblematic gestures invite the reader/the Other to a diffi cult dialogue and at the same time indicate the nature of the authors’ poetic ambition. The analysis of the two pairs of poems is set in the context of the 20th-century evolution of the idea of poetic genius and the poet’s self-awareness. Crucial to this comparative study of the poetic practice of Leopold Staff, Tymoteusz Karpowicz and Krystyna Miłobędzka is an appraisal of the authenticity of their vision and the language they used to express their maximalist ambitions.
