Communicating failure mode information during design and manufacturing is a crucial task for failure prevention. Most processes use Failure Modes and Effects types of analyses, as well as prior knowledge and experience, to determine the potential modes of failures a product might encounter during its lifetime. When new products are being considered and designed, this knowledge and information i...

A failure mode and effect analysis (FMEA) was applied to improve the design of concrete ties in ballasted track for North American heavy haul applications. A literature review was conducted on concrete tie failure modes, failure effects, and failure causes. A survey of railroads and transit authorities in North America provided a ranking of the most critical concrete tie failure modes. The most...

Nowadays there is need of high performance of computer system in distributed environment. As the system mean time before failure correspondingly drops, applications must checkpoint frequently to make progress. However, at scale, the cost of checkpointing becomes prohibitive. A solution to this problem is multilevel checkpointing, which employs multiple types of checkpoints in a single run. Ligh...
