LONG WAVES IN RECTANGULAR TANK GENERATED BY PLANE
The surface form of heavy liquid in the rectangular wave tank covered with long waves over the flat bottom is i nvestigated. The waves are generated by the horizontal h armonic oscill a tions of the screen - formed wavemaker. The accurate solution to the

Unitary rotation and gyration of pixelated images on rectangular screens [PDF]
In the two space dimensions of screens in optical sy stems, rotations, gyrations, and fractional Fourier transformations form the Fourier subgroup of the symplectic group of linear canonical transformations: U(2) F $\subset$ Sp(4,R). Here we study the action of this Fourier group on pixellated images within generic rectangular $N_x$ $\times$ $N_y ...

Exploring impacts of inlet condition on flow structure in a Compound open-channel using PIV [PDF]
A compound open channel is composed of the main channel and flood plain. In experiments with compound open channel conducted to ensure that the flow is uniform and fully developed, it is necessary to study the distribution of discharge in the main ...

Model tests on large-section and shallow soil rectangular pipe jacking
During the construction of pipe jacking tunnels, the simultaneous injection is a key in controlling the surface deformation and jacking force. At present, the traditional researches on the simultaneous injection are mainly limited to those on the slurry ...
