Purpose. To develop mathematical models and techniques to model stepless transmissions operating as a part of a diesel loco motive, to improve reliability of the results of diesel locomotive movement under actual operating conditions. Methodology. Values of kinematic parameters, power parameters, and energy parameters are identified with the help of solving a system of algebraic equations by Simulink subsystem of Matlab system. Integrated study of changes in basic transmission param eters of "input differential" and "output differential" in terms of its operation within both transport and traction ranges is necessary to determine the initial data to model braking process of a mine diesel locomotive. findings. The paper has performed comparative analysis of "input differential" and "output differential" hydrostatic me chanical transmissions (HMTs) by means of integrated study of changes in power parameters, kinematic parameters, and energy parameters of the transmissions in terms of traction and transport ranges of motion of a mine diesel locomotive. Values of these parameters are determined by means of solving the system of algebraic equations being considered as the development of a set of mathematical models and techniques to model stepless transmissions operating as a part of a mine diesel locomotive. originality. The obtained results of integrated study of changes in power, kinematic and energy parameters of "input differen tial" and "output differential" HMTs in terms of their operation within both transport and traction ranges indicate that each transmission has its own strengths and weaknesses. That is why the both HMTs will be used in future while analyzing a braking process of a mine diesel locomotive. Practical value. The developed structural transmission scheme, mathematical model explaining changes in kinematic param eters and power ones, determined kinematic, power parameters and efficiency of hydrostatic drive in future can be applied as the initial data to model a braking process of a mine diesel locomotive.
The purpose of the work is to analyse the features of electronic dance music (EDM) in the cultural space of Ukraine in the late 2000s and early 2010s based on the study of online publications on electronic dance music, review the most important events in EDM culture and provide an interpretation of the most relevant musical trends over the past two decades. The research methodology includes descriptive and interpretive approaches, statistical analysis, synthesis and generalization of the collected information to complete the scientific understanding of the electronic dance music existence in Ukrainian culture. The scientific novelty. The festivals of electronic dance music in Ukraine in the late 2000s -early 2010s were studied for the first time; the study describes the features and genre diversity of electronic dance music and the most popular trends of techno and house music. Conclusions. The study has demonstrated that electronic dance music in Ukraine was the most popular in the late 2000s -early 2010s, when it was played not only in dance clubs, but also at festivals. The following EDM festivals in Ukraine have been analysed: "
