Предложен метод решения основной задачи небесной механики об эволюции системы N материальных точек, взаимодействующих между собой по закону всемирного тяготения Ньютона. Метод основан на сведении задачи Коши для системы ...

Scanning electron microscopy was used to study the structure of flakes in samples of large 40KhGM-steel forgings obtained under industrial and laboratory conditions. It has been established that manganese sulfide inclusions ...

The article suggests theoretical justification for the development of power efficient electric drives for the crude hydrocarbons transport process units based on intelligent control and monitoring systems. The strategies ...

With declining reserves of rich iron ores, the processing of lean and complex ore is a priority. Such ore may only be used in the blast furnace in limited quantities. A method is developed for the selective reduction and ...

A study was conducted to demonstrate self-organization of perturbations in fluid films. The flow of such self-organization perturbations in the films considered in the rectangular system of coordinates OXYZ for the Reynolds ...

The paper is devoted to the possibility of determinate and probabilistic scattering under various assumptions of the state of the locations of medical robots in both fault-tolerance and vulnerable environments. The ...

Results are presented from the development and testing of a new design of shears for cutting rolled shapes of circular cross section and thick-walled tubes. The shears employ a mechanical cutting scheme based on translational ...

Rankine-Hugoniot relations for the hyperbolic model of a multivelocity multicomponent mixture have been given. The shock adiabat consistent with the model's equations has been calculated for a gas-liquid mixture. The ...

We discuss the approach to simulate the experiments with surface and underwater vehicles in towing tanks for Reynolds numbers corresponding to the full-scale ones using discrete injection of polymer additives. Experimental ...

Concurrent games, in which participants run some distance in real physical time, are investigated. Petri Markov models of paired and multiple competitions are formed. For paired competition formula for density function of ...
