Simulating calculation on maximum allowable displacement of the free end of pipeline based on butt welding

open access: yesYou-qi chuyun, 2021
Due to the corrosive perforation and third-party damage, multiple leakage accidents occurred to the long-distance oil and gas pipelines, for which on-site emergency repair was required, and further pipeline alignment should be performed before welding ...

Precision Southern Hemisphere pulsar VLBI astrometry: techniques and results for PSR J1559-4438

open access: yes, 2008
We describe a data reduction pipeline for VLBI astrometric observations of pulsars, implemented using the ParselTongue AIPS interface. The pipeline performs calibration (including ionosphere modeling), phase referencing with proper accounting of ...

Interpretation of surveying and mapping geographic information policies for long-distance pipelines and countermeasures for application

open access: yesYou-qi chuyun, 2021
Due to the national requirements for keeping the surveying and mapping geographic information confidential, the sharing of long-distance pipeline coordinate data is always a difficulty for the application of informatization of the pipeline operators ...

Analysis of LIGO data for gravitational waves from binary neutron stars [PDF]

open access: yes, 2003
We report on a search for gravitational waves from coalescing compact binary systems in the Milky Way and the Magellanic Clouds. The analysis uses data taken by two of the three LIGO interferometers during the first LIGO science run and illustrates a ...

Fuzzy Damage Analysis of the Seismic Response of a Long-Distance Pipeline under a Coupling Multi-Influence Domain

open access: yesEnergies, 2018
For a long-distance pipeline, the seismic load is a four-dimensional space-time excitation that simultaneously changes with time and space. In this work, a novel random space-time seismic model is established for a long-distance pipeline, which uses the ...

Segue: Overviewing Evolution Patterns of Egocentric Networks by Interactive Construction of Spatial Layouts

open access: yes, 2018
Getting the overall picture of how a large number of ego-networks evolve is a common yet challenging task. Existing techniques often require analysts to inspect the evolution patterns of ego-networks one after another.
