A numerical procedure for the solution of the one-dimensional Schrdinger equation (the finite-difference boundary-value method), especially suited for problems having periodic nature, is presented and applied to the problem of hindered internal rotation. The accuracy of the numerical method, as a f...
HF Energy of a Many-Electron System In the Hartree-Fock approximation, the wave function of anN-electron system is a Slater determinant or a linear combination of a few Slater determinants, like Ψ=1N!|χ 1(1)χ2(1)⋯χN(1)χ 1(2)χ2(2)⋯χN(2)⋮⋮⋱⋮χ1(N)χ2(N...
Wave energy is one of the most promising renewable energy sources of the last few decades. Wave power has been investigated in Europe since the Seventies. In 1974 Prof. Stephen Salter proposed one of the first Wave Energy Converters (WEC), called Duck, at the University of Edinburgh. In the...

When the wave packet undergoes an order-unity distortion, its energy is deemed to have cascaded to a smaller scale5. MHD turbulence is called “imbalanced” if the power of counter-propagating Alfvén waves is different in both directions with respect to the background magnetic field direction2,...
Fig. 1. Schematic of an array of box-type OWCs parallelly installed at the facing-wave side of a very long flexible floating breakwater. Offshore WEC-infrastructure integrated systems include WEC-floating breakwater hybrid system, WEC-Offshore Wind Turbine (OWT) hybrid system, WEC-floating platfo...
这个部分需要设置k-points mesh的精度;一个rule of thumb是:n_a\times a\ge 30。其中n_a指的是a方向的k点数目;a指的是a方向的长度(可以从CELL PARAMETER找到)。 automatic指的是自动生成K点。如果要设置\Gamma点,那么就要改成:1 1 1 0 0 0。
Another method to estimate the roughness length employs the following function of wave parameters [17]: (4.29)z0HS=1200(HSLP)4.5 where HS is the significant wave height and LP is the peak period wavelength. As said earlier, the turbulence intensity is lower not only because the smaller surfac...
The strain sensitivity curves as a function of frequency for the experiments used in the paper are included in thefiles/folder in.npzformat. Their content can be easily unpacked through a simple script, e.g. for the LISA experiment LISA=np.load(S_h_LISA_xcosmo.npz')LISA_freq=LISA['x'...
These functions are based on existing algorithms published by the USGS[1] and Natural Capital Project[2]. Those tools are implemented in ArcGIS with Python code and use raster land layers instead of vector spatial data. Thewave_energyfunction calculates the wave energy flux from either (a) the...
