By considering an exciplex system consisting of collective molecules in interaction with both the 'pumping' fields and the biophoton fields, the two-level exciplex model and the three-level exciplex model are presented. They are useful for the investigation of the quasi-stationary behaviour of biophoton emission, and biophoton emission as a dynamic process(More)
Sometimes, the traditional refrigeration system should operate even in cold seasons to control the temperature in data centers, control units of power stations. There are problems about operation economy and operating stability. The combination of refrigeration systems with heat pipes could provide a solution to weaken the problems. In this paper, a(More)
In the context of nonlinear finite element (FE) method, this paper presents a computational framework for 'exact' response sensitivity analysis of soil-structural interaction (SSI) systems based on the direct differentiation method (DDM). The DDM requires analytically differentiating the FE algorithm for the response computation with respect to material,(More)
