AbstractAbstract
[en] The article presents theoretical aspects of the influence of environmental changes on the extent of the recognized stress in the case of airfield concrete slab. Analyses included actual measurement data from 34 weather stations located within the area of Poland. The results obtained between 2000 and 2016 were used to prepare climatic data base of the selected regions. The analyses included maps of typical values taking into consideration daily, monthly and annual variations. In case of exemplary data from Kielce station, the influence of external conditions on the extent of the registered stress and deformations of airfield concrete slab was determined. According to the obtained test results, the significant influence of environmental conditions on changes of concrete slab strains was confirmed. Recommendations aiming at limiting negative influence of environmental conditions on concrete slab strains were suggested in case of the analysed area. (paper)

AbstractAbstract
[en] For a better determination of solidification end position during the process of soft reduction to confirm the reasonable reduction position and reduction area and to get the better slab quality, by analyzing the force behaviour of slab shell during soft reduction process, a force dynamic determination model for the end position of liquid core of slab during soft reduction process has been built. The variation trend of reaction force and total pressure of segment clamping-roller with the changing of position of solidification end can be got by the using of model calculation, and by analyzing this trend, a force feedback-based model has been proposed for checking the end position of liquid core. The veracity of the force feedback-based model has been verified by using nail-shooting approach. (paper)

AbstractAbstract
[en] The technology of a monolithic construction is a well-established practice among most Russian real estate developers. The strong points of the technology are low cost of materials and lower demand for qualified workers. The monolithic construction uses various types of reinforced slabs and foamed concrete, since they are easy to use and highly durable; they also need practically no additional treatment. (paper)

AbstractAbstract
[en] The post-tensioned slabs have been using for many years. Over the years, many guidelines regarding design methods and calculations have been issued. There are several methods of static analysis and obtained results interpretation. It should be noted that the selection of method has a large impact on the final results in terms of required amount of presstresing steel. It is a great importance for economic aspects of realization of the post-tensioned slabs. In this paper the results of analysis of flat post-tensioned slab are presented. The calculations were carried out using two methods: the equivalent frame method and final elements method. The differences between these two methods and the impact of the selected method on the final usage of the prestressing steel are described in detail. (paper)

AbstractAbstract
[en] The surface plasmons and polaritons in thin flims cut from a uniaxial crystal are discussed. Only two geometries are considered, with the anisotropy axis normal or parallel with the film surface. The dispersion equations are solved in the long wavelength limit and for very large film thickness the known results for semi-infinite medium are recovered

AbstractAbstract
[en] The generation of terahertz electromagnetic radiation when a laser pulse propagates through a low-density plasma slab is considered. It is shown that terahertz waves are excited because of the growth of a weakly damped, antisymmetric leaking mode of the plasma slab. The spectral, angular, and energy parameters of the terahertz radiation are investigated, as well as the spatiotemporal structure of the emitted waves. It is demonstrated that terahertz electromagnetic wave fields are generated most efficiently when the pulse length is comparable to the slab thickness.

AbstractAbstract
[en] The C/sub N/ method of solving the transport equation has been developed at Saclay during the past few years. This method is based on a lemma proved by Placzek; an integral equation is provided for the angular flux at the boundary of the various media, and its kernel is the infinite medium Green's function. Four plane geometry problems are solved in one-velocity theory, with a linearly anisotropic scattering kernel: the albedo for the Milne problem, the extrapolation length for the same problem, albedo and transmission factor for slabs, and the critical thickness for slab reactors. Numerical results are obtained and compared with data computed by reference methods

AbstractAbstract
[en] We suggest a geometrical framework to discuss the action of slabs of negatively refracting materials. We show that these slabs generate the same orbits as normal materials, but traced out in opposite directions. This property allows us to confirm that the action of any lossless multilayer can be optically canceled by putting it together with the multilayer constructed as the inverted mirror image, with ε and μ reversed in sign
