In this paper, a new image de-noising method is proposed by using the threshold method based on nonparametric adaptive estimation which is presented by Birge-Massart in Ridgelet domain.

该文在有限Ridgelet域中，结合Birge-Massart等提出的非参数自适应估计理论，提出一种新的二维图像去噪方法。

Simulation results suggest how to choose appropriate parameter α and threshold Neg of length of effective gene. The ideal choice allows the model to achieve high level of diversity and adaptability, and have good nonself detection rate with a very low rate of self detection.

通过仿真实验证明合适选择α参数以及有效因子的长度阈值Neg，能使该模型具有很好的多样性和自适应性，呈现出较高的"非我"检测率和低的误检率。

By adding new self or nonself to meet system need dynamically, and standing a clonal selection additionally in the system after adding new self or nonself, some detectors arriving to threshold can be activated, others are to die or wait to be activated.

通过新增自体或非自体来动态满足检测系统的要求，并在系统中再一次进行克隆选择，达到激活阀值的检测器才能被激活，而没有达到的或死亡，或等待被激活。

The threshold values for normal and abnormal auditory ossicular chain were -600～-200 HU and 50～300 HU respectively.

正常及异常中耳的观察阈值分别为-600～-200 HU和50～300 HU。

Direct difference is sensitive to noisy data, so a threshold limitation is given, which can not only filter the result from noisy data but also pick edge points up according men's desire. On the other hand, artificial intelligence is used for segmentation in reverse engineering. Because the essence of segmentation is clustering similar characteristics and self-organizing feature mapping is one function of neural network, SOFM network is used for segmentation in the thesis, coordinates and normal of data points is took as the characteristics vector.

第二种方法，基于双向角度微分的边点提取法，针对三维正交模型采用基于截面线的方式组织数据，此方法比基于曲率半径方法更简洁，不用进行曲面拟合，大大提高了计算速度；计算过程中由数据点的直接差分逼近微分，但直接差分对数据误差敏感，为此，本文提出了阈值过滤的方法，一方面过滤了数据误差在计算结果中引起的噪音，另一方面可以按照设计意图控制边点的提取；来决定是否提取光滑交接的边点。

Using the changing rate of maximum feed-rate as a threshold,the surface of the part is divided into different areas according to the values of normal curvature radius.Then the feed-rate is adjusted by constant velocities of cutter contact,thus the adaptive variation of feed-rate can be reached.An example is given to prove the ra...

以最大工作进给速度的变化比率为阈值，把零件表面的法曲率半径划分为不同的区域；在不同的曲率区域内，分别以恒定的刀触点速度对进给速度进行修正，修正后的进给速度随着零件表面曲率的变化而自适应变化；实例表明该方法具有合理性和有效性。

By using center manifold theorem and normal form of maps, we also present formal proofs of the supercritical flip bifurcation at the bifurcation point. Above this threshold, there is a characteristic sequence of bifurcations, leading to chaotic dynamics, which implies that the dynamical behavior of the single species model with birth pulses are very complex.

利用单参数族映射的中心流形定理、正规型和指数积分函数的性质，得到了具非线性出生率或具密度依赖成熟率的混杂矩阵模型正平衡态的存在性和稳定性、超临界分支以及各种复杂现象甚至混沌。

The algorithm uses a Markov process, making use of a large number of normal data transfer training probability matrix to construct the normal data behaviour profile, and it raises the efficiency of detection by the choice of detection window or setting a certain threshold.

该算法采用了一阶马尔科夫过程，利用大量正常数据训练概率转移矩阵，构造正常数据的轮廓，并通过对检测窗口和阈值的选择提高检测效率。

The characters of different illumination conditions are studied and the corresponding algorithms of gray image edge detection are proposed. In normal condition, the Sobel operator can be used to get the image edge. When the illumination is faint, the image is first enhanced by the MSR, and then the variance threshold algorithm is employed. While the light is strong, the image edge can be got by gray expand. At last, the instance image is detected.

通过对不同光照情况下的图像特征分析，提出了不同光照情况下的图像边缘检测算法：正常光照条件下采用Sobel算子进行边缘检测；弱光照条件时先用MSR (multi-scale retine)进行图像细节增强处理，再利用类别方差自动门限法得到图像边缘；强光照条件下通过灰度扩展，将所感兴趣的灰度范围放大得到图像的边缘。

Beginning with the Nazi eroticization of the bodily ideal, Linke moves across the 1945 threshold to explain how the new Germany organized its understanding of the body: public nudism the revival of the cult of the body the attempt to de-eroticize white nakedness Linke also examines the the 'feminization' of the 'guest' labourers; foreign workers needed during the reconstruction boom and then regarded as unwelcome aliens and the ways in which today's German left and militant right converge.

随着身体的理想，在1945年的门槛林克纳粹eroticization举动解释如何开始新的德国组织的理解身体：公众裸体主义的身体，以德企图eroticize白色裸体林克也邪教复兴检查是的'女性化'客人'劳动者；在重建繁荣需要外国劳工，然后为不受欢迎的外国人，以及如何把在今天的德国左翼激进的权利和衔接。
