    Opis:
    The new efficient method of modeling and thermodynamic analysis of power engineering systems has been presented. With its help a comparison of different structures and investigation of the influence of a particular constituent process onto the whole system efficiency is possible. The shaft work or the energy is the main thermodynamic quantity taken into account in analyses, and the appropriate dimensionless modeling parameter has been introduced.

    Opis:
    Measurements of hydro-acoustic noise emitted from vessels are a.o. a subject of the tests carried out in the control measurement ranges of the Navy. The measurements are performed both on anchored and floating vessels. Acoustic field of vessels is changing along with their speed changing and is associated with acoustic activity of wave sources installed in vessel’s hull (main engines, electric generating sets, reduction gears, pumps, shaft-lines, piping, ventilating ducts etc) as well as hydro-dynamic sources such as screw propellers and water flow around the hull [5, 7]. Vibration energy generated by the onboard devices is transferred through ship structural elements to water where it propagates in the form of hydro-acoustic waves of a wide frequency band.

    Opis:
    This paper deals with results of identification tests of acoustic field spectrum of underwater noise generated by ship in motion. The field is connected with acoustic activity of ship mechanisms and devices in operation. Vibration energy generated by the mechanisms and devices is transferred through ship structural elements to surrounding water where it propagates in the form of acoustic waves of a broad band of frequencies. In the publication results of identification tests of underwater noise generated by a ship in motion, are presented.

    Opis:
    This paper presents results of research on spectral structure of underwater noise acoustic field radiated into water by selected ships moving in shallow waters. Underwater acoustic field of ships in motion is associated with acoustic activity of ship mechanisms and equipment under work. Vibration energy radiated by the mechanisms and devices is transmitted by ship structural elements to surrounding water where it is propagated in the form of acoustic waves of a wide frequency band. In this paper are presented results of the research on propagation of energy of acoustic waves in the near fiel, obtained from acoustic pressure measurements by means of two sensors located close to each other.

    Opis:
    Compared to other Polish emigrant cohorts, the broadly understood Solidarity emigration to the USA and Canada of the early 1980s occupies a distinctive place. Their literary output produced for the most part in English came quickly and entered the mainstream book market already at the turn of the century. Even though their fiction deployed fairly typical themes of dislocation, emigrant experience and construction of immigrant identity in the receiving country, its uniqueness rests in the two-fold vision of two very closely related generations: the first generation emigrants who left Poland as adults, as well as their children, classified as the generation 1.5, who experienced growing up in two countries. In their semi autobiographical fiction, writers representing the older generation such as Eva Stachniak and Czesław Karkowski, devote much of their work to justifying the decision to emigrate and attempt to position their successful characters within the narrative of the American dream. In contrast, younger generation authors such as Karolina Waclawiak and Dagmara Dominczyk, construct a much darker vision of the fragmented immigrant identity that leaves their fictional characters psychologically fragile. In their struggle, they identify the cause of this suffering in their parents’ choice to leave the home country.
