The initial powders and coatings were investigated by means of X-ray diffraction. The structures of coatings from more complex mixtures on different base materials depended on the combination of treatment parameters: the thickness of initial powder, the quality of fluxes, and the electron beam current. The interaction of alloying elements and their mutual influence on polymorphism of Ti also determine the phase content and the structure of the coatings.","PeriodicalId":421846,"journal":{"name":"Proceedings of the 6th International Scientific and Practical Conference of Students, Post-graduates and Young Scientists.

The implementation of these methods helps to avoid only physical nature (hardware) faults. When designing software support, design faults should be attended, because of their \"sleeping\" character (those faults originate due to the mistakes and oversights of humans that occur while they design software systems). Here, the author describes how N-version programming as an approach to fault-tolerant software system design, permits the solution of the stated problems successfully.","PeriodicalId":421846,"journal":{"name":"Proceedings of the 6th International Scientific and Practical Conference of Students, Post-graduates and Young Scientists.

The precise localization of trains on lines of a railway station is necessary to solve these problems. For the solution of these problems the data pictorial model for simulation of way station and current situation on the station is used. The necessity of application of pictorial model results from the technological process for the solution of the problems. The workstation of the railway station-master assistant having standard equipment is equipped additionally with a personal computer (PC) with an intelligence system storing the scheme of station lines, introduced in linearly-topological data model. The station equipment includes a system of video observation consisting of a set of controlled TV cameras, placed on searchlight towers which permits viewing, on a video terminal or screen of the PC, of the picture obtained from them. The given system of TV cameras is constructed in such a manner that on a monitor screen it is possible to obtain the picture practically of any part of station lines in one of several possible projections.","PeriodicalId":421846,"journal":{"name":"Proceedings of the 6th International Scientific and Practical Conference of Students, Post-graduates and Young Scientists.

For this purpose current stabilizers or amplifiers with current output are used, at which the target current changes proportionally to the source signal. Such circuits are necessary in devices whose resistance is proportional to some external effect. The amplifier circuits with current output permit, with large accuracy, the realization of Ohm's law, if the resistance of load changes. In this case, the load voltage should be strictly proportional to its resistance.","PeriodicalId":421846,"journal":{"name":"Proceedings of the 6th International Scientific and Practical Conference of Students, Post-graduates and Young Scientists.
