In this paper, theoretical mathematical model of reservoir simulation using tracer is given and an ideal tracer reservoir model is established. Numerical simulation results show that the injected concentration of tracer has no effect on breakthrough time and peak time of the tracer, but breakthrough concentration and peak concentration increase along with the injected tracer concentration. The higher...
The artificial prosthesises currently used are only different in the femoral head size, neck length and stem thickness, but there is not any individualized prosthesis. At present, prosthesis looseness is the main problem of artificial femoral replacement, and individual matching level of joints is the bottleneck of restricting prosthesis replacement surgery. If we can design and produce corresponding...
With the rapid development of computer, applied mathematics and reservoir engineering, which have provided a technology platform for the scientific management, digitalization and informationization of reservoir, the integration research of geological modeling and numerical simulation is more and more emphasized in oilfield. In this paper, the mathematical theory of streamline simulation is given....
Quantile regression can be used for some biostatistical research as the first choice. But direct applications are often hampered by the problem of quantile regression planes' crossing in finite sample cases. After research, the Box-Cox transformation is used to avoid the crossing problem. Integrating Box-Cox transformation with quantile regression, we suggest a new method. And the fitting of salmon...
