A series of model resistance tests of the 4500m3/h self-propelled cutter suction dredger are simulated based on the computational fluid dynamics software in this paper. By comparison of experimental data and CFD calculation results, the reliability of the CFD tools in the study of resistance performance of the vessel with notch in bow is proved. Then the variation of resistance of the vessel with...
More and more organizations begin to employ information technology capability strategy in the dynamic and complicated environment, but from the information technology capability to innovation performance, it should be some effects of other variables. And also, the focus point of relevant research changes from whether it should be build the information technology capability to the mechanism of how...
The regular pattern of temperature change in a coalfield fire area while the fire is being extinguished was studied. To determine the extinguishing effect, a series of linear, logarithmic, polynomial or exponential mathematical regression models were constructed using the observed temperature data from the Xinjiang coalfield fire extinguishing project. The quadratic polynomial mathematical model had...
