Analysis of Barriers to the Development of Industrial Internet of Things Technology and Ways to Overcome Them

The development of the digital economy requires the compilation of a roadmap for the development of all the end-to-end technologies included in the cluster of technologies that need to be developed to a new level. At the first stage, anticipating decisions on state financing of this cluster, a list of critical end-to-end technologies is compiled. The second step is the preparation of roadmaps for each of the selected critical technologies. As a rule, many experts are involved in drawing up roadmaps, including foreign experts. As a rule, the team of such experts is headed by an organization that has received instructions to develop a roadmap on a competitive basis. Of course, not all the wishes of all experts are taken into account by such an organization; therefore, there may be alternative opinions and alternative roadmaps, or additions to the developed roadmaps. If the roadmap developed by the governing organization is approved, alternative documents are only of perhaps scientific interest. If the roadmap developed by the core team of experts is not approved due to its insufficient completeness, the decision seems to be postponed, and the specified roadmap should be corrected by adding information from alternative documents, which, of course, should be done taking into account the opinion of all experts in the field. Since the approved roadmap for the "Industrial Internet of Things" direction does not yet exist, the authors consider it useful to present their position on this issue

Monte-Carlo simulations of the two-dimensional NMR T 2 - T 2 exchange of fluids in porous media

The effects of molecular exchange processes on the two-dimensional (2D) NMR T2-T2 distributions obtained by Laplace inversion were studied by numerical simulations. The Monte–Carlo technique is used to generate free random walks of a large number of molecules within space regions characterized by different relaxation times. Molecular exchange processes are considered during CPMG encoding periods as well as during the storage period, τstore. Systematic simulations were performed as function of NMR parameters like the storage period, τstore and geometric or physical system properties

Statistics of interatomic Ni-Ni bonds in Ni-based ternary solid solutions with non-magnetic elements and their magnetic behaviour

The drop of ferromagnetic moment in the ternary solid solutions Ni1-x-yCuxDy, (D = Zn, Si, Au, Al) is analyzed in terms of the statistical model of the environment-dependent moments. This probabilistic model shows that the disappearing of one Ni atom ferromagnetic moment can be assigned to the replacement of at least four Ni–Ni bindings, out of twelve, in pure nickel. This paper aims at discussing all these features that, from the point of view of macroscopic equilibrium states, are related to the distribution of local bonds, provided by the peripheral electrons of the substitute atoms dissolved in the Ni matrix
