Abstract: In-pipe intelligent isolation plugging tools (IPTs) are crucial in pipeline maintenance. During the plugging process, the flow field around the IPT changes drastically, resulting in vibration and instability of the plugging ...

Abstract: The distribution of internal defects in large-diameter steel pipes can be complicated. Due to the harsh working environments involved, the manual grinding method for correcting such defects is inaccurate, inefficient, and ...

Abstract: The Global Positioning System (GPS) and the Global Navigation Satellite System (GLONASS) have been used to estimate ocean tide loading displacement (OTLD) with high accuracy; however, GPS has been problematic at K2 and K1 ...

Abstract: The performance of fuel cells depends on the rate parameters of the kinetic reactions between the involved species, among other conditions. The determination of these parameters is crucial for ...

Abstract: Site displacements caused by ocean tide loading (OTL) can reach more than several centimeters vertically, particularly in coastal regions. An ocean tide model typically is used to correct OTL effects, but these model ...

Abstract: Ocean tide loading (OTL) correction is becoming more and more crucial in high precision geodetic data processing. The published global ocean tide models show good agreement in deep oceans and exhibit differences in complex ...

Abstract: The use of artificial neural networks (ANN) for modeling complex processes is an attractive approach that has been successfully applied in various fields. However, in many cases the use of an ANN alone may be inadequate ...

Abstract: A fractal calculation method was developed to investigate the self-similarity of the time distribution of microseismic events during the evolution of rock bursts. Microseismic data, which were utilized for back-analysis ...
