查询词典 tensor density

First, a non-negative tensor factorization algorithm is improved by imposing sparseness constraints on it. Secondly, the bispectral images of mechanical signals are obtained and stacked to form a third-order tensor. Thirdly, the improved algorithm is used to extract features, which are represented by a series of basis images from this tensor. Finally, coefficients indicating these basis images' weights in constituting original bispectral images are calculated for fault classification.

首先，改进已有的非负张量分解算法，加入稀疏度控制策略；其次，将机械振动信号的双谱图像堆叠为一个三阶张量；然后利用改进后的分解算法对该张量进行二次故障特征提取，得到代表局部特征的"基图像"；最后，通过计算得出基图像在构成原双谱图像中所占的权重，并将得到的权重向量用于故障分类。

In this framework, image frame, audio and text are represented, which are the three modalities in video shots as data points by the 3rd-order tensor. Then a subspace embedding and dimension reduction method is proposed, which explicitly considers the manifold structure of the tensor space from temporal-sequenced associated co-occurring multimodal media data in video. It is called TensorShot approach. Transductive learning uses a large amount of unlabeled data together with the labeled data to build better classifiers. A transductive support tensor machines algorithm is proposed to train effective classifier. This algorithm preserves the intrinsic structure of the submanifold where tensorshots are sampled, and is also able to map out-of-sample data points directly. Moreover, the utilization of unlabeled data improves classification ability.

在此框架中，视频镜头首先被表示成由视频中所包含的文本、视觉和听觉等多模态数据构成的三阶张量；其次，基于此三阶张量表达及视频的时序关联共生特性设计了一种子空间嵌入降维方法，称为张量镜头；由于直推式学习从已知样本出发能对特定的未知样本进行学习和识别，最后在这个框架中提出了一种基于张量镜头的直推式支持张量机算法，它不仅保持了张量镜头所在的流形空间的本征结构，而且能够将训练集合外数据直接映射到流形子空间，同时充分利用未标记样本改善分类器的学习性能。

We first prove a formula to calculate the magnetic field in the internal region of magnetized objects on the viewpoint of magnetization, and then use the formula to define the point-function demagnetizing tensor and also prove some properties of the tensor. Finally we use this formula to construct a new method to predict the induced magnetic field of naval vessels in a nonuniform applied field, and we call it 'the Magnetization Method', in which the point-function demagnetizing tensor is used.

We calculate the energy-momentum pseudo-tensor of relic gravitational wave of both the polarized states by Riazuelo-Uzan expression of the energy-momentum pseudo tensor in the Cartesian coordinates, we can see that energy density and momentum densities of relic GWs are dependent on cosmic scale factor and square of the amplitudes,. At the same time, the energy density of relic GWs is positive definite, the momentum densities components have reasonable physical behavior,and their values are independent on the directions.

我们还用Riazuelo-Uzan表述在直角坐标系下对双极化态的遗迹引力波的能量动量赝张量进行计算，发现双极化态的遗迹引力波的能量张量密度与他们的振幅的平方和宇宙学尺度因子有关，他们的能量密度是正定的，大小跟传播方向无关，即遗迹引力波在宇宙学尺度上是各项均匀同性的。

The discovery of annual density bands of mass coral skeleton had a profound effect on coral paleoclimatology, and many patterns of density bands have been revealed throughout the global tropic ocean since then. At the first stage, people tended to explore the control factors of density changes from the environment where the coral grows, but they did not succeed. Since later part of 1980s, some researchers have focused on the skeletal architecture and integrated the signals of both environment condition and skeleton density bands to reveal the mechanism of skeleton density changes, and finally a model of skeleton growth was developed which can explain the almost existed patterns of skeleton density changes.

块状珊瑚骨骼密度条带年周期的发现对后来的珊瑚古气候研究产生了深远的影响，随后又发现世界各热带海域的珊瑚存在多种多样的骨骼密度变化模式，起先常从珊瑚的生长环境中寻找骨骼密度变化的控制因素，但是没有成功，从80年代后期，部分学者试图从珊瑚骨骼构架本身出发、综合考虑环境因素和骨骼密度条带之间的关系来探求骨骼密度变化的机理，并提出了一个可以解释大多数块状珊瑚骨骼密度条带变化模式的骨骼生长模型。

The difference of bulk density of coastal soils took an effect on infiltration rate and diffuse rate. The infiltration rate and diffuse rate of coastal soils which bulk density was small were big. The water transmitting experiment of coastal soils showed that the saturated conductivity of different layers in soil profile were great, and the saturated conductivity of undisturbed soil was highly higher than that of disturbed soil. The saturated conductivity of coastal soils embanked earlier was lower than that of coastal soils embanked later. Under different water content, the unsaturated conductivity of coastal soils had a great change and the bulk density had an effect on unsaturated conductivity. The soil with a low bulk density had a high unsaturated conductivity. Chlorine ion moved in coastal soil was an inert ion. The distribution of CU in soil was definite and repeated, which is no relation with the time and velocity of infiltration. The concentration of infiltration solution and the texture of coastal soils had no apparent effect on solute movement synthetic dispersion coefficient, while bulk density took an apparent effect on solute movement synthetic dispersion coefficient. Synthetic dispersion coefficient of coastal soils increased as bulk density decreased.
