Robotics And The Role Of Robots In Human Life

This article claims that robotics has enormous potential to improve all aspects of human life. While these advantages are restricted to highly specialized environments such as factories, robotic technology has advanced to the point that it can now be used in the human environment on a daily basis. However, without a thorough understanding of how humans and robots communicate, this integration would fail.

Improving The Economic And Environmental Performance Of Engines Through The Use Of Alternative Fuels

The rapid depletion of fossil fuels and the steady increase in human energy consumption, leading to environmental pollution, are creating a situation characterized as an energy-environmental degradation. For this reason, extensive research is being conducted to address the problem of reducing the consumption of non-renewable energy sources and pollution of the environment with toxic waste. In such cases, the concept of hydrogen energy, ie the use of hydrogen as a source of energy on a large industrial scale and in road transport, is important. The prospects for the use of hydrogen for automobile engines can be summarized as follows. First of all, environmental friendliness, renewability and unrestricted raw material reserves, as well as unique engine performance; these allow hydrogen to be used without drastic changes to modern engine designs.

Algorithm Of The Electronic Digital Subscript On The Basis Of The Composition Of Computing Complexities

In article the new algorithm of a digital signature in composition of the existing difficulties is developed: discrete logarithming in a final field, decomposition of rather large natural number on simple multipliers, additions of points with rational coordinates of an elliptic curve. On the basis of a combination of difficulties of discrete logarithming on a final field with the characteristic of large number, decomposition of rather large odd number on simple multipliers and additions of points of an elliptic curve develops algorithm of a digital signature for formation. The conventional scheme (model) of a digital signature covers three processes: generation of keys of EDS; formation of EDS; check (authenticity confirmation) of EDS. The idea of a design of the offered algorithm allows modifying and increasing crypto stability with addition to other computing difficulties. It is intended for use in systems of information processing of different function during forming and confirmation of authenticity of digital signature.

Dynamic Models Of An Electromechanical Electric Drive System Of An Asynchronous Motor

Asynchronous motors require its study not only in stationary modes, but also in dynamic ones. At the same time, this makes it possible to formulate the corresponding requirements for automatic control devices of a regulated IM, the implementation of which will ensure the optimal course of transient processes in the electric drive system; it requires its study not only in stationary modes, but also in dynamic ones. This simultaneously makes it possible to formulate the corresponding requirements for automatic control devices of variable IM, the implementation of which will ensure the optimal course of transient processes in the electric drive system The study of electromechanical transient modes requires a joint consideration and solution of the equations of equilibrium of electrical quantities in the windings of the machine and the equations of motion of an electric drive.
