Abstract The Span-based model can effectively capture the complex entity structure in the text, thus becoming the mainstream model for nested named entity recognition (Nested NER) tasks. However, traditional Span-based models decode each entity span

Free span is a great danger and an unavoidable problem for buried gas pipeline. In this paper, a method for identifying buried gas pipeline free span based on vibration signal analysis under internal excitation load is experimentally studied. Collect

Subsea pipeline is crucial for oil and gas transportation. It is advantageous to be able to identify the free-spanning segments of a long subsea pipeline. The existing technologies for detecting the support condition of buried subsea pipelines are co

Regular pigging operation of the pipeline inspection gauges (PIGs) is crucial for pipeline transportation. However, the PIG is often stuck when it runs in the oil and gas pipeline due to the interaction between spherical sealing cup and dent inside t

Free span along a buried gas pipeline is inevitable since the buried gas pipeline is constantly exposed to the complex surrounding environment. A free span is commonly identified by manual inspection, sonar technology, or a remote robot. The main dis
