Gaussian modeling and Schmidt modes of SPDS biphoton states

A double-Gaussian model and the Schmidt modes are found for the biphoton wave function characterizing spontaneous parametric down-conversion with the degenerate collinear phase-matching of the type I and with a pulsed pump. The obtained results are valid for all durations of the pump pulses, short, long and intermediately long

Estimation of the total inelasticity coefficient in interaction of greater than or equal to 20 TeV hadrons with lead

Experimental data on the interaction mean free path of hadrons with energy E 20 TeV in lead obtained with multilayer X-ray emulsion chambers(XEC) are compared with results of simulation of nuclear-electromagnetic cascades in lead chamber. It is shown that, to explain experimental data, the value of the inelasticity coefficients, K .8 should be assumed

Degradation and Restoration of Superconducting Parameters of HTS Tapes under Mechanical Loads and Heat Treatment

As it is known, the current-carrying properties of HTS tapes are structurally sensitive parameters, and largely depend on the grain size, morphology, texture, presence of pinning centers and others. These structural parameters may be changed by shock loading actions. The report presents the results of research of varying intensity shock loads effects from 0.35 to 100 J/cm2 on the structure and characteristics of superconducting Bi-2223 tapes. A strong degradation of the critical current

Methodology for failure analysis of complex technical systems and prevention of their consequences

The paper presents a study on the methodology of failures and their possible consequences analysis. Analysis of failures and their consequences is carried out for newly developed or modernized products and it is one of main activities in the reliability assurance system. The methodology is applied to the analysis of all designed systems, starting from the earliest stage of development, in order to evaluate the approach to development and compare the advantages of the design solution. The considered analysis of failures and their consequences of components is a part of the complex analysis of reliability of the whole product. Depending on the complexity of the design and the available data, a particular approach may be chosen for the analysis. In one case, it is a structural approach, in which a list of individual elements and their possible failures is compiled. In another case, it is the functional approach, which is based on the statement that each element must perform a number of functions that can be classified as solutions. The results provide a scheme for conducting the analysis and finding solutions to prevent them. The conclusions say that the level of detail determines the level at which failures are postulated

Assessment of the recreational potential of the forest territory of the Sverdlovsk region

The purpose of this study is to present our vision of assessing the recreational potential of the territory (RPT) for its effective management. We suggest using this territory assessment method, which consists of two main stages: assessment of the recreational component of the natural environment and assessment of the necessary amount of investment to use the recreational biodiversity of the territories.The article analyzes the approaches and presents the results of a comprehensive assessment of the recreational potential of the forest lands of the Sverdlovsk region. Created a map ranking the Sverdlovsk region according to the results of research with application for developing a comprehensive assessment of RPT on the methods, developed on the basis of the theory of "games with nature": the method of structured comparison of RPT on the Hurwitz criterion, aspiring to the maximum and to identify the factors dominating the impact from the application of the Wald criterion. Based on the conducted research on the analysis of the influence of forests on the formation of recreational characteristics, the authors obtained weighted average generalized coefficients of recreational attractiveness of forests of different types in the forest management areas of the Sverdlovsk region and identified 10 forest-cadastre areas in the Sverdlovsk region. This paper also presents a developed and tested method for a comprehensive assessment of the recreational potential of forest lands in the territory of the Sverdlovsk region in order to attract investment. Preliminary investment volumes for the development of the Sverdlovsk region's RPT (based on the cost of forest biodiversity) are presented. We consider the proposed territory ranking to be a necessary indicator for effective management of the subject's territories. © The Authors, published by EDP Sciences.

“Digital Generation”: Threats and Hopes in the Era of Information-Digital Civilization

The article refers to the information and digital civilization — its threats and hopes formed by it to the “digital generation”. On the one hand, an identifier is the name of a managed object in a digital society. Each step of the “digitized citizen” can be checked, serve as a test of loyalty to the system, to agree with the worldview and ideological attitudes adopted in it. Civilization atrophies and deforms auditory and visual physiological analyzers, changes mental features of the younger generation. On the other hand, young people, like the Pythagoreans who offered us the digital Universe, perceive the digitalization of social life organically as integration into the natural environment of life. Information and digital civilization gives birth to the world society as an alternative site of politics, differs from the main international society, creates its own logic of communication, mobilization and action. If international diplomacy creates a formal, hierarchical, formal and exclusive atmosphere concerning the events of intergroup relations, transnational digital network (TDCN) are informal, egalitarian, highly inclusive and open to multilingual presentation and alternative forms of political expression. Information and digital civilization creates limitless conditions for the development of human ability to foresee and foresee the future, and not a prophet, not a magician, not a psychic, and the most common, the average person. After all, our mind develops faster than the body, which creates the preconditions for the fact that humanity, which has become a digital community, will be able to abandon the harmful “benefits” of civilization without becoming a victim
