It has been concluded that it is necessary to make more full use of the opportunities of digital sociology in promoting further institutionalization of tutoring support for educational rehabilitation of disabled people

Digitalization of mass media as a factor of influence on trust in artificial intelligence

The article discusses the influence of media digitalization on the individuals’ trust in artificial intelligence technologies. The authors study the key features associated with the current state of the media market, as well as highlight the risks that affect the development of the media and consumer confidence in them. An important place in this work is given to the analysis of the media digitalization. The main elements that reflect the consequences of this process are described, as well as global trends associated with the mass media market. In this paper, the aspect of individuals’ trust in artificial intelligence is studied, in particular, the main reasons for distrust in the phenomenon under study are considered. The authors have identified the relationship between the process of digitalization of the media and the trust of individuals in artificial intelligence. In the final part of the article, the authors present the results of digitalization of the media in the context of the transition to new formats, and also reveal the existing mechanism of the impact of this transition on people’s trust in artificial intelligence

Justification of the criteria requirements for fillers in mixtures for 3D construction printing

ABSTRACT: Introduction. As part of the task to create new materials for additive technologies, an analysis of the situation was carried out, and a problem was identified with the lack of common approaches to selecting raw material components for mixtures. Theoretical concept. Based on the approaches of fundamental structure rheology, physicochemical mechanics of disperse systems, the theory of packing of granular media, we theoretically justified the criteria requirements for the characteristics of fillers and suggested quantitative criteria for their evaluation. It was proposed to use these quantitative criteria for a preliminary comprehensive assessment of fillers when designing compositions of mixtures for 3D construction printing. Materials and methods. The characteristics of the fillers were evaluated using scanning electron microscopy with a scanning electron microscope Thermo Scientific™ Phenom™ Desktop SEM and processing of images by the ParticleMetric software package as well as using laser granulometry with a laser analyser of particles Analysette 22. Results. We assessed the cement and 5 types of fillers that had different sizes and played different roles in the formation of the mixture properties. We also identified their estimated criterial characteristics, including the average particle diameter, granulometric constant, and particle shape coefficient. Boundary values of these characteristics were determined for particles of different morphology and dispersion degree. Conclusion. Based on the application of the suggested theoretical approaches, we determined the lines of research associated with obtaining experimental patterns of the impact of the criterial characteristics of fillers on the rheological characteristics of mixtures as well as with these characteristics according to their significance and justifying the requirements for the range of quantities of fillers depending on their size, shape, and granulometry

The effect of microporous polymeric support modification on surface and gas transport properties of supported ionic liquid membranes

© 2015 by the authors; licensee MDPI, Basel, Switzerland. Microporous polymers based on anionic macroinitiator and toluene 2,4-diisocyanate were used as a support for 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]) and 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([emim][Tf2N]) immobilization. The polymeric support was modified by using silica particles associated in oligomeric media, and the influence of the modifier used on the polymeric structure was studied. The supported ionic liquid membranes (SILMs) were tested for He, N2, NH3, H2S, and CO2 gas separation and ideal selectivities were calculated. The high values of ideal selectivity for ammonia-based systems with permanent gases were observed on polymer matrixes immobilized with [bmim][PF6] and [emim][Tf2N]. The modification of SILMs by nanosize silica particles leads to an increase of NH3 separation relatively to CO2 or H2S

Application of SMAs in modern spacecraft and devices

The use of shape memory alloys in spacecraft and devices was suggested practically as soon as the first materials of this type had been discovered and investigations of their unique functional and mechanical properties had begun. However, various reasons led to a more than 30-years delay in realization of ideas in devices and constructions that were launched to the space. The first of the devices – the drives to unfold a transformable construction – were installed on the Russian spacecraft Progress-40 only in 1989. Conservative attitude of engineers, designers and those heading the space industry was overcome. Since then, materials with shape memory effect (SME) were applied in the different space vehicles: on the orbital station Mir, the spacecraft Clementine the satellites MightySat I, FalconSat, others satellites, aboard the space shuttle Columbia, the Mars rover Sojourner. Designers of spacecraft have shown a considerable interest in materials with shape memory effect in the last five years. As of today, various devices using SME are being developed, for example, for the Helios2 telescope, Rosetta/Midas, Soho, Cassini projects, for the International Space Station

Thermo-Mechanical Properties of an NiTi-Shape Memory Alloy after Dynamic Loading

The results of the comparative study of a quasi-equilibrium NiTi alloy's thermo-mechanical response to high-rate and quasi-static straining in the temperature range of 100-300°C, which included the $A_{f}$ and the $M_{d}$ temperatures, are considered. The existence of B2 → B19' and B2 → R → B19' martensitic transformations, associated with the heterogeneous distribution of Ni₄Ti₃ precipitates is shown to result in shaping of martensitic and austenitic two-way shape memories, the simultaneous presence of which determines the reversing shape memory effect. The suppression of stress-induced B2 → B19' transformation at temperatures higher than the $M_{d}$ temperature resulted in austenitic two-way shape memory only. Distinct dependences on the temperature of the critical stresses that initiate B2 → B19' and B2 → R → B19' martensitic transformations in austenite are shown to be the reason for the participation of the irreversible mechanisms of straining at the earliest stages of tension, whatever the strain-rate applied, thus annihilating the distinctions between the quasi-static and high-rate straining processes. As a result, the thermo-mechanical properties acquired after tension become practically independent of the strain-rate
