  • Means and methods of innovative management of innovative startups. Part II

    The work is devoted to the means and methods of innovative management. Associated mainly with startup projects. This refers to an extended concept of startups, not only and not so much as an organization that creates a new product or service in conditions of high uncertainty, but as an innovative project with a high degree of risk. The algorithm for implementing startups is considered, and the factors that influence the introduction of innovations, both external and internal, are presented. Much attention is paid to effective tools and methods for implementing startups. Such as the application of systems analysis and diversification of production. It is shown that one of the foundations of innovative technological business in the economy is currently played by industrial-agricultural symbiosis. All of the above questions are illustrated by numerous specific examples. The main goals and principles of innovation management identified in the course of the conclusion are logically derived from the totality of which. The work is of a scientific and practical nature. It can be used both in scientific research of modern business processes and for practical guidance in conducting specific campaigns.

  • About possibilities of management of ecological and economic risks of investment projects

    This article discusses the possibility of managing environmental and economic risks of investment projects. Environmental efficiency is an important indicator in assessing the effectiveness of an investment project. It is revealed that when assessing the environmental efficiency of an investment project, it is necessary to use the established standards and agreements, normative legal acts in the field of environmental law. However, the legislation in the Russian Federation in the field of environmental risk assessment requires accurate calculations that will facilitate the task of the investor in the field of adoption of an effective investment project. It is analyzed that the final decision on the implementation of the project depends on the quality of the assessment.

  • Overview of approaches to adaptive error correction when transmitting images over a noisy channel

    The directions of modern research in the field of adaptive error correction, which can be applied when transmitting images in JPEG 2000 format over a noisy channel, are examined. Adaptive correction at the network level allows you to maintain a given percentage of packet delivery. Uneven protection at the application level is intended for use in broadcast broadcasts and allows the consumer to receive an image of various quality depending on the state of the network. Adaptive uniform protection at the application level is focused on point-to-point transmission and is aimed at receiving the maximum image quality by the receiver. The network layer tools discussed can be combined with the application layer tools.

  • Determination of critical stresses in shells of high flexibility

    The article is considered the wall stability of a steel cylindrical pre-stressed granary, compressed by the friction forces of grain and shell, taking into consideration the influence of the grain internal pressure, its elastic resistance from the inside and the elastic resistance of the pre-stressed shell outside. In this case, the initial and subcritical deflection of the shell is assumed to be axisymmetric, and the loss of the shell stability occurs with the formation of asymmetric deflection. The given solution of the problem allows to determine the magnitude of the critical efforts taking into consideration the influence of the grain internal pressure, its elastic repulsion, the magnitude of the initial deflections and the ratio of shell dimensions.

  • Cognitive model of the civil-legal attitudes’ structure of the population of the Rostov region

    Civil-legal attitudes of the population determine the degree of its participation in the socio-political processes of society development. The aim of this work is to create a cognitive model that reflects the structure of civil-legal attitudes of the population of the Rostov region, depending on the socio-demographic (age) differences. The object of the study is the civil- legal attitudes in the consciousness of the population of the Rostov region, differentiated by age (youth, the population of economically active age, the older generation). The subject research field includes certain aspects of the structures of civil-legal attitudes of the population of the Rostov region, depending on the belonging to different socio-demographic groups of the population. The methodological basis for the development and research of the considered substantive models is a system analysis in combination with a cognitive approach. In the framework of the study, the cognitive model of civil-legal attitudes of residents of the Rostov region, allowed to identify three components, the degree of severity of each of which has an age determination. To the greatest extent, age differentiation affects the value-semantic, normative and situational components of the cognitive model, which indicates an increasing mental distance between the strata of the older and younger generation of representatives of the Don region. At the same time, there are practically no generational imbalances in the institutional component, which characterizes the role of the state in the formation of the legal and civil field.

  • The concept of control method of the tracking camera of a rotary-wing aircraft based on the theory of fuzzy sets

    The basis of solving the problem of automatic takeoff and landing of helicopters is the problem of orientation of the aircraft relative to the landing site. Existing approaches are based on a combination of satellite positioning technology and sensors. Such solutions have a significant drawback - low positioning accuracy. In this regard, it is necessary to develop new methods that provide low computational complexity and high positioning accuracy relative to the landing site. The article provides an overview of modern solutions in the field of autonomous control of aircraft. The concept of a method for solving the problem of orientation of a helicopter relative to the landing pad is proposed. The approach is based on the use of a camera following the heliport sign. Determining the landing site is based on the theory of fuzzy sets and complex linguistic variables. Complex linguistic variables have three-dimensional membership functions, thus avoiding the problem of uncertainty. Simplification of the computational process is achieved through the use of projections of sections of three-dimensional membership functions.

  • The model for overcoming the risks of destroying the life world of a young family (based on materials from the Rostov region)

    This article analyzes strategies to overcome the risks of a breakdown in the life of a young family. Based on the results of an empirical study conducted in the Rostov region, the authors of the article identify micro- and macro-strategies for overcoming the risks of destroying the life world of a young family within the framework of cognitive, value, and behavioral levels. The authors conclude that an important role in overcoming cognitive-value risks is given to microsocial strategies, where the family occupies key positions. Macro-social strategies are represented by the work of social institutions such as the state, the media, and education. According to the authors, the symbiosis of the selected strategies is the most effective for reducing the risks of the collapse of the life world of a young family.
