The steel damageability simulation under random loading by the power, energetical and strain fracture criterions

Effort to describe effect of variable amplitude loading character on fatigue damage cumulation is committed for a metal material of a structural part. It is proposed to quantify the influence of loading character on durability life via damage model incorporating the nonstationarity factor and the spectrum fullness factor. Experimental evidence and analytical results of the proposed model are correlated

Microporous poly- and monocrystalline diamond films produced from chemical vapor deposited diamond-germanium composites

We report on a novel method for porous diamond fabrication, which is based on the synthesis of diamond-germanium composite films followed by etching of Ge component. The composites were grown by microwave plasma assisted CVD in CH4-H2-GeH4 mixtures on (100) silicon, microcrystalline- and single-crystal diamond substrates. The structure and the phase composition of the films before and after the etching were analyzed with scanning electron microscopy and Raman spectroscopy. The films revealed a bright emission of GeV color centers due to diamond doping with Ge, as evidenced by photoluminescence spectroscopy. The possible applications of the porous diamond films include thermal management, surfaces with superhydrophobic properties, chromatography, supercapacitors etc

Luminescent diamond composites

Diamond is valuable material with extraordinary high thermal conductivity and transparency in a wide spectral range from UV to IR and longer wavelengths. Defects and impurities in the diamond lattice can absorb and emit light at wavelengths specific for each of such “color centers.” Particularly, the vacancy-related defects in diamond, such as nitrogen-vacancy (NV) or silicon-vacancy (SiV) centers, are actively investigated due to their potential for biomedicine, quantum optics, local thermometry and magnetometry. Although a great variety of different color centers in diamond are discovered, only a limited number of those point defects can be reliably reproduced in synthetic diamond, obtained either by chemical vapor deposition (CVD) or high-pressure high-temperature (HPHT). An alternative approach to producing luminescent diamond-based materials is to integrate stable non-diamond sources of luminescence in the form of nano- or microparticles of foreign materials into the pristine diamond. The produced diamond composites possess excellent properties of diamond combined with optical emission characteristics, which cannot be provided with intrinsic defects in diamond. The good candidates for the materials of such impurities are well-investigated fluorides and oxides doped by rare-earth elements (RE) or other luminescent chalcogenides such as sulfides, selenides and tellurides. Here we briefly review recent achievements in fabrication and properties of these new luminescent diamond-RE composites, compare them with luminescent properties of doped diamond, and outline prospects for applications of the luminescent diamond composites for photonics, markers, monitors of high-power synchrotron, X-ray beams and X-ray lasers

Information model of the internet portal of moscow urban development Информационная модель интернет-портала градостроительного развития территорий г. Москвы

The article describes an approach to developing the Internet portal of urban development in Moscow. The purpose for creating the portal is the analysis and monitoring of integrated urban development of Moscow. Database of the Internet portal is based on the data available in the bodies of executive power of Moscow of various levels. Data is grouped according to the relation to different urban programs and characteristics of autonomous regions.As a result of raw data processing, the user gets information that reflects the level of urban development in the area visually. The use of the proposed web portal will allow users to work interactively, provide them with remote access to the necessary information and will provide information in multimedia format. The technology of processing the data of the information-analytical Internet portal ofMoscow urban development is designed for several groups of people: specialists of the city and the municipal executive bodies (full access); specialists of organizations participating in investment or construction (limited access)population (access to public information). Configurable access levels for working with data allow using this resource in the open network Internet in order to inform residents about the urban development of the municipal districts of the city.<br>Рассмотрен подход к формированию данных, форм отчетности и уровней доступа интернет-портала градостроительного развития территорий г.

In this article, the algorithm underlying the methodology for construction of distributed intelligent power management systems applicable to construction facilities in the context of arbitrary limitation of resources is considered by the authors. The methodology consist of a sequence of operations, including the analysis of design solutions in terms of the systems engineering, identification of their energy consumption rate, assessment of the feasibility of actions aimed at the automation or organization of an intelligent management system.The authors consider the algorithm of the calculation of specific energy consumption rate of each engineering system, as well as the calculation of acceptable process losses (based on the regional standards).After that, the most power-intensive engineering systems are identified. First, conversion of true values of measurement of energy consumption in tons of oil equivalent must be performed to assure the unbiased evaluation of the power consumption rate of engineering systems, irrespectively of the energy nature. Thereafter, the power consumption rate of management systems is calculated, and their degree of automation is assessed from the viewpoint of its technical and financial efficiency. The final step consists in the preparation of design specifications and estimates.<br>Рассмотрен алгоритм методики построения распределенных интеллектуальных систем управления энергопотреблением комплексов объектов в условиях произвольных ограничений ресурсов.
