Russian education faces a difficult task in defining what its education system needs to be achieving to maximize its effectiveness in a changing society. Both educational officials and the general public need to be more aware of this challenge and how to deal with it. 相似文献

We present a simulation of the behavior of a homogeneous group of robots in an environment with obstacles. The problems of 2D flight of robots to different target objects were considered. The questions of the mutual dependence between local control rules and global adaptive group behavior and the synthesis of group control were studied and an analysis of the controllability of the group targets in environment with obstacles was performed. The results of the simulation are presented and examples of the operation of the simulation program are given. 相似文献

The information and intellectual product concepts in a new infological and documentological paradigm
Yu. V. Nesterovich 《Scientific and Technical Information Processing》2015,42(4):264-273
The need is considered to integrate the concept of information in the course of the development of a new info(rmo)logical and documentological paradigm through the concept of an intellectual product that is realized by the use of sign systems. The formation of this paradigm allows for coordination of the emergence of theoretical concepts with the basic schemes of metatheory or general theory rather than with the definitions of terms in the regulatory literature. 相似文献

This paper presents an ontological approach to generating automated medical technological records (MTRs). The medical organizational TR meta-ontology has been developed based on the paper variant of 63 technological records that are used at the Medical Center of the Bank of Russia. The paper describes the key elements of an automated MTR. The MTR ontology for bronchial asthma attack is used as an example. 相似文献

This paper describes a new multi-method technology PAKS-M (Progressive Aggregation of the Classified Situations by many Methods) for the multi-criteria choice. This technology provides reducing the dimension of the attribute space, constructing several hierarchical systems of composite criteria and an integral quality index that aggregates initial attributes as well as the classification and/or ordering of multiattribute objects using different combinations of several decision-making methods. The technology is based on the knowledge of experts and/or the preferences of a decision maker (DM). It significantly reduces the time and complexity of solution of a multi-criteria choice task, and allows a decision maker to conduct a meaningful analysis of the results. This technology was used for the multi-criteria selection of a prospective computing complex. 相似文献
