{ In real-time cooperative editing systems, independent operations on any part of the shared document may be generated from multiple cooperating sites. It is very important and technically challenging to ensure that the eeect of executing an operation at remote sites, in the presence of concurrent execution of independent operations, achieves the same eeect as executing this operation at the lo...

During the operation process of high-voltage insulators, characteristics assessing their technical state are evaluated by using remote contactless monitoring and subsequent forecasting residual life based on developed set diagnostic parameters critical defects. Special attention is paid to challenges practical application for insulators’ current operating state. Measurements partial discharges ...

Attributing a cyber-operation through the use of multiple pieces of technical evidence (i.e., malware reverse-engineering and source tracking) and conventional intelligence sources (i.e., human or signals intelligence) is a difficult problem not only due to the effort required to obtain evidence, but the ease with which an adversary can plant false evidence. In this paper, we introduce a formal...

The increment integration of renewable distributed energies means the desired operation of the electric power system will significantly depend on the performance of primary energy. In this order, an integrated approach for mutual interaction between the electricity and natural gas systems has been considered for the purpose of ensuring optimal energy exchanging between the electric power system...

In this paper, the problems of diagnostics of main propulsion marine engines are presented. Diesel or turbine engines are used for main propulsion of vessel power plants. Marine engine is a complex technical object. For the purpose of diagnostics it is convenient to divide the engine into several units – subsystems such as: piston –crank assembly; working medium exchange system, fuel supply sys...
