We find and investigate the effect of an anomalous increase in the relative dielectric permittivity of a model composite dielectric consisting of a binder (paraffin) and a filler (100 nm particles of technical carbon). It is shown that the relative dielectric permittivity increases by more than 5 times compared with the estimated value for the mixture. The model was developed on the basis of the tendency of the conducting carbon nanoparticles to aggregate into electric dipoles preserving the anomalously large permittivity of the composite. It is shown that the effect depends on the preparation technology. If the melt solidification occurs under ultrasound vibrations the effect decreases by a factor of 3. The proposed model can be successfully used to develop space oriented composites because they should have enhanced conductivity combined with the low relative dielectric permittivity.
The Informational paradigm of discourse to the XXIst century is replaced by communicative; due to the spread of the Internet, new features and models of communication based on the subject-to-subject concept of hypertext are formed. Tekstogennost’ as a set of anthropogenically-technical factors of generation, transmission, exchange texts of public communication, leading to the formation and operation of new types of vehicles and generators of information in all spheres of life, which have an impact on them, becomes the essential characteristic of socio-economic discourse. The role of the professional communication support (PR, mass media) of all processes becomes more essential. Thus, the textual, philological, humanitarian dimension determines the effectiveness of social development.
For the last 5 years the market of intellectual capital has dramatically decreased, the graduating students’ knowledge quality steadily decreases and the ambitions for the fee increase. This article describes the application of currently most promising methods of (1) network (graph) theory, (2) data mining and (3) subject-oriented approach to business process modelling for creating and automation of innovative process and therefore for maximization of ROI (return on investments) in universities intellectual and social capital. Descried approach represents the High School activity as the knowledge-made process, reveals students, capable of innovation activity for their further deep study of innovation practice, transfers the moment of novation forming with further discussion the possibility of novation realization as an innovation into the educational process, develops maximum person-independent procedures of innovation work groups forming and expert communities for evaluation of both novations and innovation budgets. The given research was held in a frame of the contract № 13.G25.31.0096 with the Ministry for Education and Science of Russian Federation «Creation of hi-tech manufacture of unstructured information processing in cross-platform system on the open-source software basis in order to increase management efficiency of innovative activity of enterprises in modern Russia».
In many organizations implementation of innovation is initiated by the management with application of so-cold “top-down” approach: strategic targets and key success factors with the initiatives of its achieving are formed and consolidated in different regulations, procedures, rules and instructions, which are brought to concrete employees later. The feedback from employees is occurred on the fact of initiative execution in form of corrective procedures locally, but the forming of innovation is still the top-management prerogative.
Such centric approach is mostly demotivating approach for initiative employees, who generate, implement and use innovation ideas. For this problem correction hybrid methods are used. The creation of special department inside the company is supposed to be done. It bears duties of innovation catalyst (usually R&D and HR departments have this role). Among other things this department is responsible for inspiration of average executive on development of innovation, determination and consolidation of corporate values and standards of behavior. In the end, the employees orientation on single corporate targets, the increase of corporate spirit would again “top-down” imposed and the department is just the retransmitter of values that are determined by the management.
How should the politics of relations between colleagues, clients and partners be naturally created and how to establish the awareness by the company employees of their personal responsibility and their personal role in corporate values realization, creation of innovation atmosphere inside the organization that does not resist the innovation? The approach, which is described in this article, supposes the forming of distributed network inside the organization with the transfer to it the general effort in the sphere of creating innovations and implementing the corporate ethics principals.
The article is based on the introductory part of the collection on “Material Culture and Technology in Everyday Life: Ethnographic Approaches” (2009). The author presents a brief review of concepts that have been lately employed in research on material or technological culture. He attempts to show that different disciplines do in fact use adjacent notions and concepts in thinking about materiality, and tries to delineate ways of bringing the different research traditions to a unified platform that could serve as a theoretical foundation for the complex materialistic study of technological culture.
This volume focuses on innovative approaches to teaching foreign language courses offered to non-language degree students. It includes essays related to the innovative use of ICTs, new developments in methodology, approaches to course and materials design, and the contribution of language theory to foreign language teaching. As the book brings together researchers and practitioners working in a variety of contexts, it provides detailed insight into ways the same challenges are dealt with in different educational environments.
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.
By using superconducting quantum interference device (SQUID) magnetometry, we investigated anisotropic high-field (H less than or similar to 7T) low-temperature (10 K) magnetization response of inhomogeneous nanoisland FeNi films grown by rf sputtering deposition on Sitall (TiO2) glass substrates. In the grown FeNi films, the FeNi layer nominal thickness varied from 0.6 to 2.5 nm, across the percolation transition at the d(c) similar or equal to 1.8 nm. We discovered that, beyond conventional spin-magnetism of Fe21Ni79 permalloy, the extracted out-of-plane magnetization response of the nanoisland FeNi films is not saturated in the range of investigated magnetic fields and exhibits paramagnetic-like behavior. We found that the anomalous out-of-plane magnetization response exhibits an escalating slope with increase in the nominal film thickness from 0.6 to 1.1 nm, however, it decreases with further increase in the film thickness, and then practically vanishes on approaching the FeNi film percolation threshold. At the same time, the in-plane response demonstrates saturation behavior above 1.5-2T, competing with anomalously large diamagnetic-like response, which becomes pronounced at high magnetic fields. It is possible that the supported-metal interaction leads to the creation of a thin charge-transfer (CT) layer and a Schottky barrier at the FeNi film/Sitall (TiO2) interface. Then, in the system with nanoscale circular domains, the observed anomalous paramagnetic-like magnetization response can be associated with a large orbital moment of the localized electrons. In addition, the inhomogeneous nanoisland FeNi films can possess spontaneous ordering of toroidal moments, which can be either of orbital or spin origin. The system with toroidal inhomogeneity can lead to anomalously strong diamagnetic-like response. The observed magnetization response is determined by the interplay between the paramagnetic-and diamagnetic-like contributions.
