Oil Pipeline Work Conditions Clustering Based on Simulated Annealing K-Means Algorithm
Found in: Computer Science and Information Engineering, World Congress on
By Ye Yingchun, Zhang Laibin, Liang Wei, Yu Dongliang, Wang Zhaohui
Issue Date:April 2009
pp. 646-650
With regards to the characteristics of work conditions on oil pipeline, such as complicated changes, lack of prior knowledge and difficult classification, simulated annealing K-means clustering algorithm are proposed. Samples, which include various work co...
Study on Leakage Acoustic Signal in Natural Gas Pipeline
Found in: 2012 Fourth International Conference on Computational and Information Sciences (ICCIS)
By Ye Yingchun,Zhang Laibin,Liang Wei
Issue Date:August 2012
pp. 1244-1247
The leakage is a serious threat to safety in natural gas transportation pipeline system. When the leakage is happening, the acoustic signal is generated by high-speed jet flow from inter pipelines. Leakage acoustic signal propagates within pipelines, and i...

Issue Date:May 2009
pp. 423-427
An improved HAZOP modeling and reasoning approach for machine safety assessment based on fuzzy information fusion is proposed in this paper to solve the problems of the quantitative information loss and the safety decision-making difficulty in mechanical s...
Data Mining Technology Based Leak Detection Method for Crude Oil Pipeline
Found in: Computer Science and Information Engineering, World Congress on
By Liang Wei, Zhang Laibin, Ye Yingchun
Issue Date:April 2009
pp. 656-660
It is well known that the work condition of pipeline, the leak included, can be identified by a pressure signal analysis. Because of the high frequency data collection and always on-line pipeline leak detection, the pressure signal brings up massive data. ...
