Математическое моделирование социальных процессов
We consider the problem of manipulability of social choice rules in the impartial anonymous and neutral culture model (IANC) and provide a new theoretical study of the IANC model, which allows us to analytically derive the difference between the Nitzan-Kelly index in the Impartial Culture (IC) and IANC models. We show in which cases this difference is almost zero, and in which the Nitzan-Kelly index for IANC is the same as for IC. However, in some cases this difference is large enough to cause changes in the relative manipulability of social choice rules. We provide an example of such cases.
The conference proceedings present the results of research of young scientists of the leading scientific organizations of Russia on a wide range of topical problems of Informatics, management and system analysis. Interdisciplinary research and intensive use of data are key features of modern science. The IMSA-2018 conference (Informatics, Management and Systems Analysis) aims to establish stable links between young scientists working in completely different scientific fields, but using similar methods and tools. Such networking can provide significant breakthroughs in research through the exchange of experiences between young and senior colleagues in conference activities. The conference was supported by: Russian Foundation for basic research (grant No. 18-37-10011), Russian Academy of Sciences.
Distant learning has weaknesses related to missing tutor and kind of autodidacticism of the process, which may cause learner’s frustration in uncertain situations and force him or her to drop the learning course. Inasmuch as it is very important to help learner to select a set of needed courses, the article deals with the task of forming the optimal individual educational trajectory of a learner when studying massive open online courses on the basis of knowledge and skills of the learner, knowledge and skills he or she wants to acquire and prerequisite and postrequisite skills and knowledge of available courses. The mathematical model is proposed, and problems of integer programming are formulated, which allow to find the optimal individual educational trajectory for different preferences of the learner
The work is devoted to the evaluation of the influence of fundamental science on macroeconomic indicators. The regression model of the specific gross domestic product elasticity is considered with the aim of revealing the dependence between the indicators of innovation and economic development. As a tool for restoring model parameters, a method of entropy-robust estimation based on the maximum entropy principle was developed. The main advantage of this approach is the invariance by measurement error distribution and the likelihood function. The developed model is used to construct a randomized forecast of GDP growth for the next 5 years.
Authors propose an algorithm for using the thermal regimes of laser gyroscopes – optoelectronic devices for measuring the angular rate of aircraft, on which they are installed in inertial navigation systems. The method solves one of the problems encountered by developers of platformless inertial navigation systems. The problem is to achieve the set accuracy of operation under high thermal loads, including internal heat dissipation on electronic components of laser gyro printing units. The application of the developed method in the design of electronic navigation allows implementing system approach to design and increase reliability and accuracy of operation to the required level.
This article is talking about state management and cultural policy, their nature and content in term of the new tendency - development of postindustrial society. It mentioned here, that at the moment cultural policy is the base of regional political activity and that regions can get strong competitive advantage if they are able to implement cultural policy successfully. All these trends can produce elements of new economic development.
