This paper presents novel approach to the Huffman’s asynchronous sequential circuit two valued Boolean switching system design. The algorithm is implemented as software using distributed, service oriented application model with means of the web service component design. It considers method implementation challenges, both towards Moore and Mealy structures with particular respect to the estimation of the Huffman’s minimization algorithm computational complexity. The paper provides implementation details, theoretical model estimation and experimental results that acknowledge the theoretical approach in practice. This paper also examine the multistep design process implementation and its problems inherent in web service based environment both for development and educational purposes.

Studies on the thermics, humidity and refreezing rate of two types of periglacial soils of the marine lowlands of the Hornsund area (SW Spitsbergen) were carried out during spring ablation of the snow cover (1.06.—30.06.1987). Structural soil and peat soil (moss community) were chosen. The soils were studied in places almost completely devoid of the snow cover. A considerable differentiation of temperature in vertical profile and of humidity of surface layer in both soils were found. The dynamics of ground water table and the course and depth of spring refreezing of both soils were also different. The differences reflect the different origin of soils and consequently, their different grain-size distribution, physical properties and morphology of both types of soils as well as their water balance.

A dearth of properly formulated legal definitions undermines the clarity of the law, but so do other legislative practices. Such is the case with maritime legislation too. Most evident in the understanding and definition of vessel and ship owner, this lack of clear formulation is the subject o f the article.

In the paper, the extended finite element method (XFEM) is combined with a recovery procedure in the analysis of the discontinuous Poisson problem. The model considers the weak as well as the strong discontinuity. Computationally efficient low-order finite elements provided good convergence are used. The combination of the XFEM with a recovery procedure allows for optimal convergence rates in the gradient i.e. as the same order as the primary solution. The discontinuity is modelled independently of the finite element mesh using a step-enrichment and level set approach. The results show improved gradient prediction locally for the interface element and globally for the entire domain.

The article deals with issues present in the humanities undergoing the changes due to rhetorization of contemporary culture. First I am discussing the impact of the variability of modern culture on traditional humanities (new methodology and new theory of science based on a rhetorical approach to the text and its symbolic and ideological meaning). This caused the great development of various rhetorical studies in the 20th century (from philosophy of language to practical art of speaking and argumentation). In our time, those studies answer the questions: 1) why and for what reasons do we depend on other people's views? 2) how can we exert a positive influence by text communication on other individuals? Therefore, nowadays we are seeing a new rhetorical trend in communication studies concerning all the culture texts – this trend also affects literary studies and cultural anthropology: academic disciplines which adopt the research tools of the traditional and new rhetorical workshop. This new attitude towards the humanities has an impact on general education at schools and universities.
