In order to utilize rationally the water area of anchorage basin and play full use of deepwater resource, three mooring buoy s were installed to form two 125,000 dwt double points mooring berths or three single point mooring anchorages for ship mooring or lighterage operation under favorable sea conditions.

为合理利用锚地水域，充分发挥深水资源的经济效益，设置 3个系泊浮筒，形成 2个 12 。5万吨双点系泊泊位或 3个单点系泊锚地，供船舶系泊及较好海况下进行过驳作

The detailed coefficients of DWT contain signal and noise. Instead of the soft-thresholding method, SVD is applied to decompose the signal features and noise into different orthogonal subspaces. With the reconstruction of the singular vectors in subspace, the signal features are extracted effectively.

该方法通过对每层小波分解细节系数进行奇异值分解，将其中的信号特征成分和噪声分解到不同的正交子空间中，在子空间中选取集成信号特征成分的奇异值矢量进行重构，从而提取出淹没在细节系数中的有用信号成分，最后进行小波重建，得到降噪信号。

Firstly, DWT is applied to the image, and moment invariants is extracted on fixed-size blocks of low-frequency component in wavelet sub-band to yield a reduced dimension representation.

然而，许多实际情况是要求在不依赖任何预签名提取或预嵌入信息的前提下，对图像的真伪和来源进行鉴别，这就是图像盲取证技术，也叫被动取证技术，它是一种新的图像鉴别分析思路。

This paper describes briefly the experimental results of resistance tests,pro- peller open water tests and self-propulsion tests of five geometrically similar models of a 24,000 DWT oil tanker.

本文简要介绍上海交通大学船模试验池对于24000吨油轮五艘几何相似船模的阻力试验、敞水试验及自航试验的结果，根据试验结果分析得出的下列结论可供今后船模试验研究参考之用。1。

In order to reduce the calculation complexity of DWT, a new fast Mallat decomposition algorithm is presented simultaneity.

为了减少图像小波分解的计算量，同时提出了一个快速Mallat快速分解算法。

Applied DWT to R,G,B channel correspondingly, and used three low frequent coefficients to construct a 3-level tensor. Embedding the watermark into the core tensor, which got form Tucker decomposition, could diffuse the watermark into R,G,B.

首先对彩色图像R、G、B三通道进行小波变换，然后将获得的三个低频系数构成三阶张量，再经过Tucker分解后获得核心张量，通过在核心张量中嵌入水印信息使得水印信息扩散到原彩色图像的R、G、B三个分量中。

In this paper, a new watermark algorithm for color images based on DWT is proposed.

本文提出了一种基于小波变换的彩色图像数字水印方案。
