Rewolucja informatyczna zasadniczo zmieniła styl życia ludzi w prawie wszystkich sferach. Postęp nauce oraz technologii stwarza zarówno szanse, jak i zagrożenia dla międzynarodowego pokoju bezpieczeństwa. Analiza prawnych moralnych aspektów związanych z wykorzystaniem innowacyjnych systemów uzbrojenia jest szczególnie istotna, ponieważ to te obszary będą decydować o ich wprowadzeniu. Praca stan...

We present the preliminary results of our 5-configuration, 20-pointing mosaic with the Australia Telescope Compact Array of the neutral hydrogen in the nearby spiral galaxy NGC 6744. The bulk of the HI resides in a ‘ring’ underlying the outer optical disk, with 2 HI spiral arms extending further out to almost 1 ·5 optical radii. The velocity field is fairly regular, apart from evidence for stre...

Decompositions of the rotation curves of NGC 2613, 3198, 6503, and 7184 are analyzed. For these galaxies the radial velocity dispersions of the stars have been measured and their morphology is clearly discernible. If the parameters of the decompositions are chosen according to the 'maximum' disk hypothesis, the Toomre Q stability parameter is sytematically less than one and the multiplicities o...

The design of robot dedicated to person with disabilities necessitate users implication in all steps of product development: design solution, prototyping the system, choice of users interfaces, and testing it with users in real conditions. However, before any design of any system, it is necessary to understand and meet the needs of the disabled users. In this paper, we describe our research act...

A unified view of dust grains of all sizes and temperatures in Centaurus A has been generated by combining ISOCAM mid-infrared images with optical data. In our unified V-15μm ratio image, a symmetrical bar-like structure and spiral arms of size 1.5 kpc surround the nucleus. We have overlaid the (H-K) model colour map of Quillen et al. (1993) and find a striking correspondence with the ridges se...

We have tested the applicability of the global modal approach in the density wave theory of spiral structure for a sample of spiral galaxies with measured axisymmetric background properties. We report here the results of the simulations for four galaxies: NGC 488, NGC 628, NGC 1566, and NGC 3938. Using the observed radial distributions for the stellar velocity dispersions and the rotation veloc...

We present a quantitative photometry of the bulge and disk of NGC 1288. We deduce from the multiplicity of spiral arms, using arguments of density wave theory, that NGC 1288 must be imbedded in a dark halo.
