Opis:
Visualization of science – it is a new research filed that allows large-scale analysis of the science evolution and historical changes in human activity. In the last decade it has become an important methodology used in the detection of current trends and both growth and fade of scientific domains. As the units of analysis bibliographic databases and the network data, such as logs, clicks, paths of users, blogs structure, communication packets are used. Due to graphical representations scientists can discover the critical changes in a proper research area and thus see scientific paradigms. Current article describes two examples of visualization in physics and computer science. In the first case, graphical pattern of cocitations in superstring theory illustrates the formation and development of the superstrings, including critical points – paradigms. The second one refers to the research conducted for several years by the author: visualization computer science literature from ACM Digital Library. Obtained maps well reflect the development of cloud computing methodology. The article presents an analytical potencial of visualization in science. Further more it indicates the need for a correlation between the qualitative and quantative methods in scientometrics.

Opis:
In the paper the author has described the visualization methods in acoustic flow fields and show how these methods may assist scientists to gain understanding of complex acoustic energy flow in real-life field. A graphical method will be presented to determine the real acoustic wave distribution in the flow field. Visualization of research results, which is unavailable by conventional acoustics metrology, may be shown in the form of intensity streamlines in space, as a shape of floating acoustic wave and intensity isosurface in three-dimensional space. In traditional acoustic metrology, the analysis of acoustic fields concerns only the distribution of pressure levels (scalar variable), however in a real acoustic field both the scalar (acoustic pressure) and vector (the acoustic particle velocity) effects are closely related. Only when the acoustic field is described by both the potential and kinetic energies, we may understand the mechanisms of propagation, diffraction and scattering of acoustic waves on obstacles, as a form of energy image. This attribute of intensity method can also validate the results of CFD/CAA numerical modeling which is very important in any industry acoustic investigations.

Opis:
The paper concerns GMT application for studies of the geophysical and geomorphological settings of the Weddell Sea. Its western part is occupied by the back-arc basin developed during geologic evolution of the Antarctic. The mapping presents geophysical settings reflecting tectonic formation of the region, glaciomarine sediment distribution and the bathymetry. The GlobSed grid highlighted the abnormally large thickness of sedimentary strata resulted from the long lasting sedimentation and great subsidence ratio. The sediment thickness indicated significant influx (>13,000m) in the southern segment. Values of 6,000–7,000 m along the peninsula indicate stability of the sediments influx. The northern end of the Filchner Trough shows increased sediment supply. The topography shows variability -7,160–4,763 m. The ridges in the northern segment and gravity anomalies (>75 mGal) show parallel lines stretching NW-SE (10°–45°W, 60°–67°S) which points at the effects of regional topography. The basin is dominated by the slightly negative gravity >-30 mGal. The geoid model shows a SW-NE trend with the lowest values <18 m in the south, the highest values >20m in the NE and along the Coats Land. The ripples in the north follow the geometry of the submarine ridges and channels proving correlation with topography and gravitational equipotential surface.
