This paper presents a fast approach to estimate the pose of human face from a monocular image, combining with the Chinese's appearance morphologic characteristic discovered by human appearance morphologic statistics, and cooperating with the theoretical foundation of projective geometry.

主要研究内容包括： 1。计算机辅助的面貌形态测量模型的建立。在人类学和形态学知识的基础上，分析了姿态估计技术需要使用的面貌形态特征，确定了测量涉及到的人脸特征点，形成可计算模型。

One difficulty of study is to estimate traffic fractal dimension.

其中流量的分形维数的求解问题是相关研究中的一大难点。

Because one need to search H in the range of 110, 1 and calculate the autocorrelation function many times, the concise formula of autocorrelation function of discrete fractional Gaussian noise is used to improve the processing speed. Simulation results have shown that it can estimate H accurately and more effectively than conventional LMS based on autocorrelation ftinction for both pure fractal signal and noise-corrupted fractal signal.

接着我们研究了在白噪声背景下进行分形参数估计的相关函数法，针对其在计算中需反复使用自相关函数的特点，提出了一种改进的相关函数法，实验表明，改进的方法在精度上几乎没有损失，而大幅度地提高了计算效率。

We simulate numerically the far-field intensity distribution of 6 circular arranged coherent fiber lasers and estimate its power convergence based on Fraunhofer diffraction theory.

基于Fraunhofer标量衍射理论，计算了按圆周形排列的6束光纤激光相干合束的远场光强分布，并对其能量集中程度进行了讨论。

Freeport will spend $2.7 billion on capital projects this year, down from an initial estimate of $3 billion.

Adkerson 在声明中说，今年 Freeport 公司将投资27亿美元在资本项目上，比预估的降低30亿。

This model can estimate the size of the affected area in the event of a full-bore rupture by the diameter, the operating pressure and the length of pipeline Hazard area is directly proportional to the operating pressure raised to a half power, and to the pipeline diameter raised to five-fourths power, but inversely proportional to the pipeline length raised to a quarter power.

应用该模型可以通过管道直径、工作压力和管道长度计算出全口径断裂事故的影响范围。危险影响区域与工作压力的平方根成正比，与管道直径的5/4次幂成正比，与管道长度的1/4次幂成反比。

One recent estimate found that a transition from airtight autocracy to full-throated democracy (in a hypothetical developing country of average size, income, and so on) yields a fall in tariffs of seven percentage points, from about 22% to 15% or so.

与此同时，最近的一份研究表明：由封闭的独裁统治转变为大受欢迎的民主政体（研究对象是基于发展中国家平均规模、收入及其他因素的假设模型），关税可从原来的22%降至15%，降幅达7个百分点。

An algorithm based on Huber function to estimate displacement field is presented.

提出了一种基于Huber函数的序列图像位移场估计算法。

Under some moderate conditions, the prior estimate of the solutions of the system is obtained. Making use of constructing Picard iterative sequence, Doob martingale inequality, Gronwall inequality, Borel-Cantelli lemma and some fundamental inequalities, together with the uniform Lipschitz conditions, the existence and uniqueness of the solution for stochastic functional differential equations with infinite delay is derived on the interval t0,∞.

在适当的条件下，得到了随机泛函微分方程的解的先验估计；再结合一致Lipschitz条件，通过构造Picard迭代序列，利用Doob较不等式、Gronwall不等式、Borel-Cantelli引理及一些基本不等式，得到该方程的解在区间[t0，∞]上是存在且唯一的。

The production moved off-Broadway to New York City, where she won the Joseph E. Calloway award for her performance, and was profiled in American Theater Magazine as one of ten young theater artists to watch.

生产提出过百老汇的新的纽约市，在那里她赢得了约瑟夫calloway奖，她的表现，并于异型在美国的战区杂志之一， 10战区的青年艺术家观赏。

It's a risk tradeoff, and I believe that adding test support code usually wins.

这是一个风险的权衡，我相信添加测试代码通常会占上风。
