Лабораторное моделирование электризации полимеров потоками низкоэнергетических электронов
The variation in surface microrelief of the aluminum-lithium alloy Al-2% Li-2.5% Cu and pure aluminum as a result of irradiation by powerful pulsed hydrogen-plasma fluxes at heat-flux densities of 105-5·106 W·cm-2 and pulse length 20 μsec is investigated on a Desna unit. The minimum heat-flux density from the high-temperature plasma required to initiate surface melting of aluminum materials is determined. The temperature and corresponding vaporization rate from the sample surface are estimated for several characteristic heat-flux densities.
The innovations in microelectronics education for russian aerospace industry are discussed. Three proposals are suggested: 1) special master’s programs; 2) joint departments with the enterprises; 3) special center of design and investigation in extremal electronics. It is maintained that the flexible construction “university-enterprise” would help to prepare the next generation of microelectronics engineers satisfying the aerospace industry requirements
For the development of technological innovations it is essential to ensure competent and modern commercialization within the framework of balanced business models. Multifactor cluster analysis of business models of contemporary high-technology companies and industries shows that the most effective commercialization emanate in the framework of four basic models. Company's profitability does not depend directly on the level of its technologies, but is determined by the quality of these business models. Besides trends in high-technology industries demonstrate raising segmentation and differentiation of markets and more frequent utilization of value network models.

The dynamics of a two-component Davydov-Scott (DS) soliton with a small mismatch of the initial location or velocity of the high-frequency (HF) component was investigated within the framework of the Zakharov-type system of two coupled equations for the HF and low-frequency (LF) fields. In this system, the HF field is described by the linear Schrödinger equation with the potential generated by the LF component varying in time and space. The LF component in this system is described by the Korteweg-de Vries equation with a term of quadratic influence of the HF field on the LF field. The frequency of the DS soliton`s component oscillation was found analytically using the balance equation. The perturbed DS soliton was shown to be stable. The analytical results were confirmed by numerical simulations.
Radiation conditions are described for various space regions, radiation-induced effects in spacecraft materials and equipment components are considered and information on theoretical, computational, and experimental methods for studying radiation effects are presented. The peculiarities of radiation effects on nanostructures and some problems related to modeling and radiation testing of such structures are considered.
This volume presents new results in the study and optimization of information transmission models in telecommunication networks using different approaches, mainly based on theiries of queueing systems and queueing networks .
The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
