This paper presents an extension of a comparative study of classifier architectures for automatic fault diagnosis, with a special emphasis on the Extreme Learning Machine (ELM), with and without kernel mapping. Besides the explanation of the ELM…
Asphaltene is apt to deposit from crude oil under high pressure condition, and the sediment will reduce the pipeline flow area and the performance of equipments, even block the submarine pipeline in extreme cases. The pressure is relatively high in…
The secure shutdown time of submarine oil pipeline must be determined before pipeline designed and put into production. Considering the actual operation situations, physical model of heat transfer was established for submarine oil pipelines, and…
