Migration time fluctuation strongly affects peak alignment and identification of unknown compounds, making migration time correction an essential step in capillary electrophoresis (CE)‐based metabolomics. To obtain more reliable information, metabolites with different apparent mobilities are analyzed by tandem mass spectrometry. Applying a small pressure is a common practice for reducing the analysis...
In order to study ship type of small and medium size tailing suction hopper dredger (TSHD), a comparative analysis targeted to Pallieter and Hangjun4009 is carried out. By comparing main dimensions, hull lines and principal characteristics, the usability of TSHD with a bigger block coefficient and a bigger width/draught ratio is studied. Based on calculation of wave-making resistance coefficients,...
To improve dredging efficiency and expand transportation, trailing suction dredger with shuttle barge moored at one side is applied in long distance reclamation projects. Line arrangement and line tension estimation method is established for prototype testing of this new technique. The variation rule of line tension in different operation stage is studied and a program working on optimal relative...
This paper first demonstrates that the accuracy and efficiency of the method of numerical simulation often used is not very high in predicting the slow drift surge extreme responses of a compliant offshore structure. Next, the slow drift surge extreme responses of the structure are analyzed via the path integral solution (PIS) method, and the accuracy and efficiency of the PIS method is found to be...
