Based on the complex variable method, the problem of an elliptic plate with an elliptic hole or a crack is addressed under uniform tension or pressure imposed on the boundary of the hole and on the edge of the plate. A series solution for the stress field inside the plate is derived using conformal mapping techniques, Faber series and Fourier expansion method. The stress fields around the hole or...
It will form a floating pool when LNG spilled on water or land. It may often be difficult to apply existing models or experimental data to specify the area of LNG pool. In this paper, the sensitivity of final consequence analysis results to the LNG pool area is examined. Under the condition of the same leak rate, the result shows that LNG vapor dispersion distance along the downwind reduces from 309m...
The current density distribution in a lithium-ion battery was studied by a modeling method using the finite element method. The potential and current density distributions in the lithium-ion battery were obtained through solving the equations of the modeling. Then the distribution of the temperature of the lithium-ion battery were calculated based on the conclusion of the modeling. The temperature...
Interval-censored data of gaps between recurrent events arise as the exact gaps can not be available but only know, such as whether the event time of interest is no later than the examination time. The recurrent event times subject to this interval censoring are often encountered in epidemiological studies and clinical trials. In this paper we propose a gaps model which is a derivative of the marginal...
For the switch mode power supply (SMPS) controller with high power IGBT driver devices, it is difficult to simulate as a whole one for the presented difficulties. In this paper, macro-model for power supplies controller has been established, in which the model is easy to simulate and takes quite few time to accomplish it. Furthermore, the IGBT driver device has been extracted and consequently, the...
