The return coefficient task of determination of properties of a construction design by means of the device of neural networks is considered. As model the neural network in the form of a polutorasloyny predictor with possibility of iterative accumulation of volume is taken. Each subsequent step connected with addition of a new stream of neurons, is carried out only after training of the previous stream. Coefficients of synoptic communications pay off with the help of procedure of the return distribution from a condition of a minimum of function of an assessment. Algorithms of the solution of direct and return problems of multidimensional approximation are developed.

The nano-catalyst ceria (CeO2), activated by Pt nanoparticles, is known for being prospective and efficient material widely used in catalysis, fuel elements, and sensors. One of the most up-to-date methods of catalysts' reasearch is X-ray absorption spectroscopy (XAS) that is sensitive to the chemical state of catalyst's active centers [1,2]. Using XAS in the fluorescense detection mode at CeL1 line with high precision we studied electronic structure of Pt-activated nanoparticles of ceria at various redox conditions. In order to detect partial X-ray fluorescence yield the emission line CeLγ3 was used, which allowed us to increase spectral resolution. We researched local atomic and electronic structure of the materials under study. Oxygen vacansies were found to appear on the nanoparticles surface of ceria at 5% CO He atmosphere. Theoretical modeling of the obtained spectra at CeL1-edge demonstrated good agreement with experiment.

Recommendations are given for the decision of the master plan , space planning and architectural design hotel, located in the mountainous regions of Southern Russia. Cost-effective compact centralized schemes in terms of the relief is difficult to use , so it is possible to use the blocked cells or housing related short covering pedestrian connections. In the design and orientation of the residential floors of hotels to consider an overview of the numbers of interesting species. In the design of the hotel at the foot of a steep slope is advisable to use the gallery schematic layout of residential floor gallery and orient the unfavorable shaded side of the building . When equal landscape conditions, you can use a corridor plan structure with the location of the rooms on either side. For hotels located in mountainous areas, is characterized by two main approaches to their architectural solutions : contrast harmonic landscape or merge with them.

In the field of the Museum exposition design in Russia and abroad considerable experience has accumulated. However currently we can state the absence of a comprehensive approach to create a coherent exposition system Exhibition – exhibition space. In this scientific article we formulated the concept of Space-graphic element. We have identified the structure, types and variants of use of space-graphic elements, as a special category of exposition tools in exhibition spaces. We have identified the main technical and compositional principles of space-graphic elements design. The use of those principles will allow organizing a coherent unity system Exposition – exhibition space. Concept of space-graphic elements is useful in the development of Museum and exposition activity.
