In the design and calculation of stormwater drainage systems, the design rainfall intensity plays a crucial role and is widely used in runoff calculations. Due to the influence of local climatic factors, the selection of probability distributions for rainfall frequency analysis and the methods used to determine parameters for empirical equations result in a variety of equations compared to traditional Rainfall Intensity-Duration-Frequency curves.

The auxiliary parts of the impact test hammer are only suitable for certain cases. The impact velocity of other cases are determined by measuring. Instead of measuring multiple times, the hammer velocity calculating method and program is suggested by this article for general cases and the input parameters will be changed for the other cases. The calculation results are verified by using a high speed camera to measure the hammer velocity.

The first principle calculation was employed to investigate the formation energies and structural, electronic, and magnetic properties of intrinsic and Ni-doped sodium bismuth titanate Bi0.5Na0.5TiO3(BNT). The obtained formation energies indicate that Ni atoms prefer to dope into Bi-sites in the lattice of BNT while the calculated band structure shows that the doping leads to the emergence of new midgap energy states in the bandgaps, reducing the bandgap value of doped materials.
