Based on such consideration, a strong texture description operator used in computer vision called local binary patterns is introduced. In this paper, the classic LBP method is enhanced from three aspects for facial expression recognition: image data, constructing feature way and the way of combining all extracted features.
基于以上几点考虑,本文引入了在图形学中具有很强描述纹理能力的局部二元模式(Local Binary Patterns,LBP)算法,改进了其中的三点对表情识别不利的因素:(1)将原图像经过小波包分解并在其它频率图像为零的情况下重构,得到了四幅与原图像大小相等的不同频率图像,在一定程度上增加了原图像的数据,改进了原算法数据量不足的问题。

It has become one of the important tasks in the study on modern electric system. At first, this text has briefly introduced meanings, the current development and the main methods which the electric load forecasting are used. This paper aimed at the floatability which the load data had and the nature that neural networks model is easy to fall into part infinitesimal value and low iterative speed, this paper proposed a method based on neural networks and SVM. SVM can dispel the less summation and the larger single point errors of neural networks, and the neural networks could dispel the simplification of the model of the vector support machine.
本文首先介绍了电力系统负荷预测的意义、发展现状和主要方法;针对负荷数据具有浮动的特点以及神经网络模型算法容易陷入局部极小和迭代速度较慢的缺点,提出了一种基于神经网络和支持向量机的混合负荷预测方法,此方法能通过支持向量机消除神经网络的总和较小但单点误差较大的不利现象,而神经网络消除了支持向量机的模型简单问题。

Aim at ubiquitous parallel multi-reservoir structure in our countrys basin, the universal objective function including coefficient Bi embodying a spatial significance difference at different flood control points and variable ai denoting a selection of scheduling mode is established, which provide a valid intervenor interface for flood control consultation decision. According to the real-time requirement, a model of reservoir storage allocation is proposed, which embody basic idea of phasic compensation. Passing the dynamic correction to cut down the disadvantageous influence that indetermination result in on the certain degree, joining together the step alternation solving method, this model can maximally consider bias of decision makers, ensure the rationality and practicability of the solutions.
针对我国流域中普遍存在的并联库群结构,论文提出包含不同防洪点重要性的系数β_i和选择调度模式的变量α_i的通用目标函数,为防洪会商决策,提供了有效的人工干预接口,根据实时性要求提出动态分配防洪库容的库容分配方法,体现了相机补偿的基本思想,通过动态修正在一定程度上可以削减不确定性造成的不利影响,结合分步迭代求解技术,能最大限度体现决策者的偏好,保障解的合理性和可操作性。

Results indicate that its conductibility will be improved and its density will decrease if Ce is added into the leadfree solder.In the range of 0.03wt.% to 0.05wt.% of Ce,the wettability of the solder is improved,especially when the content of Ce is about 0.03wt.%,the grains of the micro structure in lead-free solder are smaller and more homogeneo...
结果表明,添加微量的铈后,钎料的导电性能提高,密度下降;铈含量在0.03%和0.05%时可以改善钎料的润湿性;特别是0.03%质量分数时晶粒组织最为细小均匀,焊点抗拉强度也最高;当铈含量大于0.1%时对钎料的性能产生不利影响,润湿时间升高,焊点抗拉强度大幅降低,因此稀土元素铈的最佳含量应为0.03%。
