Characteristic types of operational defects which formed on the inner or outer surface drill pipes strength group G-105 are described. The results technical diagnostics were used when drilling wells in territory Dnipro-Donetsk gas-oil-bearing region. In 2018-2019, Ukrburgaz Drilling Department rejected 89 at a depth 4,000 to 6,000 meters. 
 A statistical evaluation discovered during deep (...

Abstract In a time in which significant number of launch vehicles are being developed, boosted by numerous new space actors demanding cheaper access to space, the need ensure reliability and performance successful Post-Mission Disposal (PMD) is undeniable. The first step analyse previous failures, learning from past mistakes. this paper, failures that occurred over 16 years analysed. These clas...

It is effective to improve the reliability and availability of large-scale cluster systems through the analysis of failures. Existed failure analysis methods understand and analyze failures from one or few dimension. The analysis results are partial and with less precision because of the limitation of data source. This paper presents multidimensional analysis based on graph mining to analyze mu...

Maintenance is essential to ensuring the dependability of a technical system. Periodic inspections, repairs, and renewals can prevent failures and extend a system’s lifespan. At the same time, maintenance incurs cost and planned downtime. It is therefore important to find a maintenance policy that balances cost and dependability. This paper presents a framework, fault maintenance trees (FMTs), ...

As we stride toward the exascale era, due to increasing complexity of supercomputers, hard and soft errors are causing more and more problems in high-performance scientific and engineering computation. In order to improve reliability (increase the mean time to failure) of computing systems, a lot of efforts have been devoted to developing techniques to forecast, prevent, and recover from errors...
