First, the noise energy is tracked to detect the unstable signal.

首先通过跟踪平稳噪声能量，检测能量变化非平稳的信号；

And we demonstrate that Lapalacian operator is better than identity operator in the condition of this paper, predict the noise energy.

在本文条件下，我们论证正则化算子取拉普拉斯算子比取恒等算子恢复性能好，并且预测噪声能量。

Then, noise energy can be abstracted from the nonzero frequency information of the spectrum, and signal energy from zero frequency information.

其中频谱的非零频率信息可提取噪声能量，频谱的零频率信息可提取信号能量。

To that end, IBM announced this morning a new project in partnership with the Sustainable Energy Authority Ireland (SEAI) to test the impact of noise associated with wave energy installations on marine ecosystems at two sites in Ireland.

This new research, then, will serve multiple functions: Using specialized sensors, processors, and algorithms, the project team will measure noise in real time, tracking both the noise generated by various pieces of wave energy equipment and general background noise.

The data collected will be shared widely and, with any luck, inform the creation of noise standards in the wave energy industry.
