Abstract: The instant invention relates to a method for noise reduction from a magnetic resonance sounding (MRS) oscillating signal, and more particularly, to a data processing method for reducing random noise contained in MRS oscillating signal based on joint algorithm principles of EMD and TFPF. A MRS oscillating signal is decomposed into different eigen-mode components by using decomposition characteristic of EMD algorithm; then a signal-dominated eigen-mode component is encoded as an instantaneous frequency of an analytical signal of unit amplitude using TFPF algorithm; and random noise is suppressed with the characteristics that the time-frequency distribution of the analytical signal is concentrated along with the instantaneous frequency. The method requires fewer filtering constraints and is simple to operate without need of designing a filtering interval in the time-frequency domain, and has good adaptability to the MRS oscillating signal with a low signal-noise-ratio.

Abstract: A very large floating structure based on modular units and a combined mooring system. The system includes a central large platform module, small outer platform modules, tension-legs, mooring lines, oscillating float-type wave energy converters and module connectors. The oscillating float-type wave energy converters can convert the swinging motion of the floaters into the horizontal motion of the piston rods through the gear wheel-rack transmission. Module connectors between modules are divided into two kinds of modes. One can utilize both relative torsional motion and horizontal motion between the central large platform module and the adjacent small platform modules, while the other simultaneously generates power and reduces the relative motions between the adjacent platform modules. The wave energy converters on the outer modules of the very large floating structure can generate power by absorbing the incident wave energy.
