The paper presents the results of constructing effective relay protection in power supply system a mining and processing plant (MPP). A brief description MPP is given, substitution circuits used to calculate short-circuit currents are given. statistical analysis failures electric network has been carried out, which makes it possible draw conclusions about nature ranges. Analysis registered faul...

The current practice of specifying simultaneous gap out logic at isolated high speed signalized intersections places constraints on the signal controller logic that cannot be satisfied under high congestion level. Further, it often results in degraded signal efficiency and dilemma zone protection. A stochastic approach is proposed in this paper with the objective of increasing safety and effici...

This paper reports the current status of Mg melt protection in view to identify near-future challenges, but also opportunities, for Mg melt protection of Mg-Al based alloys. The goal is to design and manufacture sustainable Mg alloys for resource efficiency, recycling and minimising waste. Among alternative cover gas technologies for Mg melt protection other than SF6: commercially available tec...

To date, much attention has focused on the advantages of public-private partnerships for critical infrastructure protection in the United States. These include reducing the duplication of effort, enhancing cross-sector communication, increasing efficiency, and ultimately achieving the protection objectives better than government or business acting independently. The benefits suggest that public...

The p-cycles can be described as preconfigured closed protection paths in a mesh network. Like rings, the protection path is preconnected in advance of any failure and protection capacity is very fast and simple. And like mesh p-cycle offers the high capacity efficiency. The use of wavelength converter in p-cycle enhances the capacity and rapid protection mechanism for mesh-restorable networks....

The relationship between trade liberalisation and the environment has been the subject of a growing body of literature in recent years. As can be seen from the differing assessment of instrument types for environmental protection, one of the important factors for the relationship between environmental protection and economic competitiveness are regulatory stringency and efficiency. This concern...

Microgrids have played an important role in distribution networks during recent years.  DC microgrids are very popular among researchers because of their benefits. Protection is one of the significant challenges in the way of microgrids progress. As a result, in this paper, a fault detection and location scheme for DC microgrids is proposed. Due to advances in Artificial Intelligence (AI) and s...

A new anti-corrosion compound, Melamine Formaldehyde (MF), was formulated by the addition of proper amount of formaldehyde to melamine under specific conditions. This compound was mixed with a novel nano powder, which was extracted from corn cob ash containing SiO2 particles, in order to improve its corrosion inhibition efficiency. This inhibitor provides a high level of protection f...
