A new calculation model is established using the simulating curves presented by Standing and Katz. The coefficients of the correlation are determined by fitting to the data of Standing and Katz Z-factor chart. The results of the two models are compared, the conclusion can be drawn that the error of LXF model is smaller than that of DAK model.

利用两种模型对不同拟对比温度和拟对比压力组合条件下的天然气偏差系数进行了拟合计算,与理论图版值的误差对比显示,在高温高压条件下LXF模型的拟合结果更优,特别是随着拟对比压力的增加,LXF模型的误差不断减小,因此,该模型更适用于高压和超高压条件下天然气偏差系数的工程计算。

Firstly, we briefly introduce the assembly model, analyze and evaluate the typical assembly model. Secondly, we propose a new-layered assembly model which is based on discrete face. At last, we briefly discuss how to use the DENEB system to abstract the information from the CAD model and how to add constrain information to the DENEB model.

首先,对装配模型进行了简要介绍,并对当前典型的装配模型及其特点进行了介绍和分析;其次,结合本文提出的装配规划算法提出了基于离散面片的层次化装配模型;最后,简要介绍了如何通过DENEB系统对CAD模型中的信息进行抽取以及如何添加约束信息。

Here the deriver' self-equilibrium velocity denotes the deriver' desired equilibrium velocity accompanying that the traffic flow is in the equilibrium state. Consequently the adaptive flux model like Navier-stokes traffic equation is derived from the extended Paveri-Fontana equation. Characteristics and the linear stability are analyzed. Numerical solution of the macroscopic traffic equations verifies rationality of our model.

把适应性公式和约化Paveri-Fontana等式结合得到扩展的Paveri-Fontana方程,通过使用Chapman – Enskog方法导出类Naveri-Stokes 方程的适应性交通流模型;通过线性稳定性分析,得到了适应性交通流模型的稳定条件;通过对算例的数值分析与其它连续性模型和交通实测数据的对比,验证了我们模型的合理性。

Then, the relations among the robust optimization model, stochastic optimization model, and deterministic optimization model are analyzed and two algorithms, enumeration method and genetic algorithm are presented.

分析了鲁棒优化模型与确定性优化模型、随机优化模型的关系,并在此基础上给出了求解鲁棒优化模型的两种方法——枚举法和遗传算法。

The calculated double differential cross section of the new model is compared with experimental data and previous SCDW calculations with single particle model. The calculated cross sections are larger than those given by previous calculations at backword and forward angles and smaller than those given by previous calculations near the quasi-elastic scattering angle. The agreement with experimental data is much improved.

模型的双微分截面计算结果与实验值以及以前采用单粒子壳层模型时的计算结果进行了比较,表明CDFM模型的引入对SCDW模型的计算结果有较大的改进,使其在大角度和极小角度区域有所增大,在准弹性散射角附近有所减小,从而能更好地与实验值相符合。

After the human is detected and extracted, we then track body parts of the human by using appearances of these parts as the features and using particle filters as the tracking kernel. In the particle filter, we adopt color histograms as the appearance features and use a specific histogram mapping to enhance the discriminability between different objects. To form a robust tracker that can distinguish target objects from background objects that have color distribution similar to those of target objects, we calculate the target similarity from both the target object model and the background model.

当人体被侦测及切割出来后,接著我们使用人体部位外观当作特徵并且使用粒子滤波器作为核心来追踪此人体,我们采等化之颜色统计表当作粒子滤波器中使用的外观特徵以强化不同物体的鉴别率,为了建立可稳健区别目标物及背景物体的追踪器,我们同时使用目标的模型和背景模型来计算目标物的相似度,为了对抗背景及目标物的外观变化,背景模型及目标物模型都是可适应变化的。
