Approach to conceptual modeling national scientific and technological potential

The paper presents a conceptual multilevel model of national scientific and technological potential in order to form and select options for the strategy of innovative development of the country. The model is based on the methodology of group verbal decision analysis and multidimensional assessment of innovations. The elements of the information-logical model and the intensity of connections between elements of different levels are evaluated by experts on qualitative criteria with verbal scale

Role of coupling delay in oscillatory activity in autonomous networks of excitable neurons with dissipation

We study numerically the effects of time delay in networks of delay-coupled excitable FitzHugh Nagumo systems with dissipation. The generation of periodic self-sustained oscillations and its threshold are analyzed depending on the dissipation of a single neuron, the delay time, and random initial conditions. The peculiarities of spatiotemporal dynamics of time-delayed bidirectional ring-structured FitzHugh-Nagumo neuronal systems are investigated in cases of local and nonlocal coupling topology between the nodes, and a first-order nonequilibrium phase transition to synchrony is established. It is shown that the emergence of oscillatory activity in delay-coupled FitzHugh-Nagumo neurons is observed for smaller values of the coupling strength as the dissipation parameter decreases. This can provide the possibility of controlling the spatiotemporal behavior of the considered neuronal networks. The observed effects are quantified by plotting distributions of the maximal Lyapunov exponent and the global order parameter in terms of delay and coupling strength.Comment: 14 pages, 17 figure

Assessment of entrepreneurial territorial attractiveness by the ranking method

The relevance of the researched problem is caused by existence of differentiation in development of separate regional units (urban districts and municipalities) within the region. The aim of this article is to offer a method, which determines the level of differentiation in development of various components of the region, and also in producing a set of recommendations for local government administration to achieve higher level in development of their territories. The leading approach to the research of this problem is the ranking method of regional units according to cumulative socioeconomic potential and integral risk. The results of the research are: the estimation procedure for entrepreneurial territorial attractiveness is offered and tried out, with the use of municipal formations of the Samara region as an example; the advantages and “bottlenecks” in development of the concrete urban district are educed; specific measures for realization of advantages and (or) elimination of “bottlenecks” are offered. The materials of the research can be useful for developing strategy for improvement of the region by regional public authorities, for leveling-off of social and economic differentiation of separate regional units, and also for developing of scientifically based municipal programs of support and development of entrepreneurship. © 2016 Karpova et al
