In this paper we propose four dimensional (4D) operators, which can be used to deal with sequential changes of topological relationships between 4D moving objects and we call them 4D development oper
The 21st Century is the time for human seeking harmonizing with environment and carrying out sustainable development strategy. But sustainable development is fa
The distributions of the wave-induced radiation stress tensor over depth are studied by using the linear wave theory, which are divided into three regions, i.e.
With the data of complex refractive index of sulfate aerosol, the radiative properties of the aerosol under 8 relative humidity conditions are calculated in thi
