Pipelines are important in transporting oil and gas in offshore engineering. During the service condition, this external water pressure could be compensated by the internal pressure induced by the gas or oil within the pipeline. However, during the pipe-laying or maintenance, the internal pressure in the pipeline will disappear. The huge external water pressure will cause local buckling or crushing...
Numerous consumer reviews of products are now available on the Internet. Consumer reviews contain rich and valuable knowledge for both firms and users. However, the reviews are often disorganized, leading to difficulties in information navigation and knowledge acquisition. This article proposes a product aspect ranking framework, which automatically identifies the important aspects of products from...
Chirp characteristics of wavelength conversion based on cross-gain modulation in quantum-dot semiconductor optical amplifier (QD-SOA) were studied. The simulation results show that low chirp can be obtained by controlling the pump and probe power reasonable. QD-SOA is suitable for wavelength conversion due to the lower linewidth enhancement factor as well as it is not sensitive to the optical wavelength.
Based on the research of failure mechanism of structure subjected to fixed and fatigue load, ship structural system reliability model is established considering fatigue-strength coupling. For the problem of large amount of calculation of searching main failure mode by using advanced branch-and-bound method, incremental time method is proposed. The bearing damage ratio and bearing force ratio parameter...
