An algorithm for the control laws synthesis for boundedly indeterminate nonlinear n-th order plants with a mathematical model in normal form and arbitrary relative order is proposed. Moreover, said plants may have an unstable state of equilibrium, and their output matrix may contain right eigenvalues. The proposed synthesis algorithm is based on the application of the combined control principle with respect to the n-th state variable derivative. And its sought for law of change is determined from the desired trajectory equation of the corresponding automatic control system by means of evaluating the state variables of its object.

This paper describes the smart city definitions and expresses a view that smart city infrastructure consists of digital technologies and information and communication technologies. We make the point that the terms Urban Digitality, Urban Computing and Urban Informatics are used to describe smart city’s underlying digital technologies in English language scientific literature. The three-step American smart city model is analyzed. The model supposes a city to collect information about itself using sensors and other devices on the first stage. On the second stage collected data is transferred by means of wired and wireless networks to be analyzed on the third stage for better understanding of the present situation and what may happen in the future. Having found that the digital technologies of internet of things, social networks and mobility correspond to the stage of «Collect», so as the technology of cloud computing is brought into correlation with the stage of «Communicate» and, finally, that the digital technologies of big data and analytics are compared to the stage of «Crunch», we reveal the substance of smart city technological base.

We consider the problem of drawing up the implementation plan of the complex programs in multiprocessor computer systems (MCS). MCS is composed of several processors working in parallel. On MCS is input multiple independent streams of applications (programs) to be distributed among the processors. The computing system may consist of identical or different from the performance of processors. Taken into account when switching between different classes of applications received by the processor. The solution is presented as a job application distribution planning problem for processors and determining a queue of requests for service processor. Optimization of planning in the case of multi-level stage is to minimize the execution time of all applications. The basis of the work of the algorithm put the mechanisms of adaptive behavior of an ant colony. The time complexity of this algorithm depends on the lifetime of colonies (number of iterations) and the number of works and performers.

In the paper there are examined intrapersonal conflicts associated with the mandatory selection of one option from two, equal their relative attractiveness. To study the effect of social environment we combined two models. The first was the previously developed model based on the theory of Bayesian model intrapersonal conflict one subject. Second was the model the spread of the epidemic presented in the base package of the agent-based modeling AnyLogic. In the numerical experiments it is studied as a manifestation on the intrapersonal level, social aspects of the environment, and Vice versa, the impact of these conflicts on the society. Found that the level of this impact strongly depends on the social value of objects of choice. If this objects important only for the individual, the near social neighbours can only shift the final probability of selection and to reduce the resolution time of the problem. The opposite effect is small. If the conflict causing problem is socially significant both for the subject and its environment, the picture changes dramatically. An association of individuals with the same choice as the conflict and the formation of clusters of two types are started with the development of the conflict in the study community. There is growth of these clusters and their absorption of each other. It was studied several scenarios final solution to the problem, such as the transformation of intrapersonal conflict in intergroup one and confrontation of the formed sub-groups, or complete absorption of one type of cluster other with the winning one of the variant. The obtained results point to the need for the study of social conflicts to pay attention to intrapersonal and the possibility of escalating into intergroup.

We consider an articulated reinforced beam from a bimodule material on an elastic base under the action of a concentrated force. Numerical investigation of the influence of the bimodule property of the beam material on the bending moment and deflection is given. The influence of the elastic bedding coefficient on the value of the maximum normal stress, the maximum bending moment and the maximum deflection is shown. Investigations were carried out for fibre-foam concrete beams, for which tensile modulus and compression moduli obtained experimentally are known. Numerical studies have shown that taking into account the bimodulity of the material, that is, taking into account the difference in elasticity modulus between tensile and modulus of elasticity for compression for concrete, leads to the need for calculation of strength both in tensile and compressive stresses.
