THE RAILWAY TO THE PACIFIC OCEAN (FOR THE 100-TH ANNIVERSARY OF THE TRANS-SIBERIAN RAILWAY)

The article gives a short description of the history of construction of the Trans-Siberian Railway. It covers the situation on Russia’s railways in the second half of the 19th century and debatable questions related to the selection of railway alignment, its function and financing of construction. The article also contains the information about work progress, its scale and construction costs

FOREIGN PRACTICE OF ORGANIZATION OF CARGO TRANSPORTATION BY INLAND WATER TRANSPORT IN RIVERSIDE CITIES

The international practice of organization of cargo transportation by inland waterways within the city has been analysed. The ways of including inland water transport into the city logistics schemes of cargo delivery in European countries have been described. The key success factors of such projects and the role of local public authorities in their implementation have been defined. Attempts at effective using of water transport as a remedy for traffic congestion in Russian riverside cities have been complemented by the progressive experience of the European Union leading countries

The formation of the methodology for the economic optimization of managerial decisions on transport

The urgency of the development of transport communications and the need to optimize their work, to develop a methodology for the study of transport as a specific industry has been substantiated. The issues of emergence and evolution of methods of economic research in transport in the context of general scientific methodology at various historical stages of development of domestic and foreign science have been considered. The characteristic of views of domestic and foreign scientists and experts on formal and substantial-essential methods of research has been given. The basic principles of a systematic approach to solving complex scientific and practical problems in the fieldof transport have been outlined

Coefficients Quantization at Off-axis Digital Hologram Wavelet Compression

Digital holographic information is compressed for storage of 2D- or 3D-objects amplitude and phase distributions, fast transmission, analyzing and displaying of these data. In this paper features of application of wavelet transforms for off-axis digital holograms compression are considered. The combined technique based on zero and twin orders elimination, wavelet compression of the amplitude and phase components of obtained Fourier spectrum and further additional compression of wavelet coefficients by thresholding and quantization is analyzed. Numerical experiments on reconstruction of images from the compressed holograms are performed. The comparative analysis of applicability of various wavelets and additional quantization of coefficients is performed. Obtained results demonstrate possibility of 180 and more times compression using iterative and noniterative methods of coefficients quantization and threshold zeroing less 80% of wavelet coefficients. Keywords: digital holography, hologram compression, wavelets, quantization, thresholding, digital image processing

The history of the government regulation of inLAND waterways before revolution in Russia

The article covers the peculiarities of development of a state management system of tsarist Russian inland water transport. Special attention is paid to the growth of inland shipping, port facilities and to construction projects of river ports. It also gives a description of functions and main activities of transport departments

Reactive diffusion in Sc/Si multilayer X-ray mirrors with CrB2 barrier layers

Processes undergoing in Sc/Si multilayer X-ray mirrors (MXMs) with periods of ∼27 nm and barrier layers of CrB20.3- and 0.7-nm thick within the temperature range of 420–780 K were studied by methods of small-angle Xray reflectivity (λ = 0.154 nm) and cross-sectional transmission electron microscopy. All layers with the exception of Sc ones are amorphous. Barrier layers are stable at least up to a temperature of 625 K and double the activation energy of diffusional intermixing at moderate temperatures. Introduction of barriers improves the thermal stability of Sc/Si MXMs at least by 80 degrees. Diffusion of Si atoms through barrier layers into Sc layers with formation of silicides was shown to be the main degradation mechanism of MXMs. A comparison of the stability for Sc/Si MXMs with different barriers published in the literature is conducted. The ways of further improvement of barrier properties are discusse
