- (Contens №2 2020)
- ... Practical value. The implication of total quality management enriches the educational policy of Ukraine with international experience in reforming the management of higher education institutions of the world’s leading countries. The reform of 659 higher education institutions, which is currently carried out by the Ministry of Education and Science of Ukraine, is based on international managerial experience that proved its effectiveness in building the economy of Japan, the USA and other countries, and especially in achieving strong outcomes in international university rankings. The implication of international experience will allow the Ministry of Education and Science of Ukraine to avoid irreparable errors in reforming the management of higher education institutions with rich history and established traditions, which together form the identity of Ukrainian science and education. ...

- 43. Synthesizing models of nonlinear dynamic objects in concentration on the basis of Volterra-Laguerre structures
- (Contens №2 2020)
- ... Findings. It is found that while synthesizing models of nonlinear dynamic objects of concentration, it is expedient to apply Volterra structures with the simulation error not exceeding 0.039 under the mean square deviation of 0.0594. Volterra models projected onto orthonormal basis functions enable simplifying parameterization and reducing sensitivity of models to noises. Among other orthonormal functions, Laguerre functions are reasonable to use. All this allows minimizing the number of model parameters in the course of their identification. ...
