The Comparative Empirical Analysis of China and India's Use of FDI and the Implications for China 中国和印度利用FDI的比较实证分析及其对中国的启示
Liu Ting, Chen Chong-xian
The economic developments of China and India, two largest developing countries in the world, have been very impressive recently, but FDI policies and real FDI inflows in two countries are different. This article compares the main factors that cause the great differences in using FDI between China and India by empirical methods. The empirical results indicate that the larger domestic market size and more friendly FDI strategies make China much more attractive than India. With the increasing wages in China, the cost oriented FDI would be greatly affected. As FDI inflows in India mainly go to the service departments, the impact would be smaller. China has lost its advantages in low cost industries, it should change its ways of using FDI.
中国和印度这两个世界上最大的发展中国家最近的经济发展令人印象深刻,但两国的外国直接投资政策和实际外国直接投资流入是不同的。本文运用实证方法比较了导致中印两国在利用FDI方面存在巨大差异的主要因素。实证结果表明,更大的国内市场规模和更友好的FDI战略使中国比印度更具吸引力。随着中国工资水平的提高,以成本为导向的FDI将受到很大影响。由于流入印度的外国直接投资主要流向服务业,因此影响会较小。中国已经失去了低成本产业的优势,应该改变使用FDI的方式。

The Understanding between Two Agent Crawlers based on Domain Ontology 基于领域本体的两种Agent爬虫之间的理解
Yingyu Wang, Yajun Du, Shaoming Chen
Ontology is widely used in the computer domain to structure concepts that represent a view of world. In this paper, we present the coordination between two Agent Crawlers based on ontology and try to measure the understanding between them relying on Formal Concept Analysis instead of comparing terms only. Here we propose a novel method on concept similarity for computing the Concept-Concept similarity, the Concept-Ontology similarity and the Ontology-Ontology similarity, and at last we can deduce the understanding between two Agent Crawlers. Finally, we can guide the crawlers effectively in our Search Engine.

An Approximate Top-k Query Algorithm in Distributed Networks 分布式网络中的近似Top-k查询算法
Wenhua Li, Wenting Yu, Xiaon'an Feng
In this paper, we propose a variant algorithm Rough Classification based on the Precutting parameter p (RCP). As the distribution of page requests generally follows a Zipf-like distribution, RCP precuts the object by predicting the derived bounds and so that to drop candidate items. By pretreatment, RCP can reduce bandwidth consumption and the run-time cost with high precision in some cases. Furthermore, by performance evaluations using both theoretical analysis and computer simulations, we show that the proposed algorithm can reduce the bandwidth consumption.
本文提出了一种基于预切参数p (RCP)的粗糙分类算法。由于页面请求的分布通常遵循类似zipf的分布,因此RCP通过预测派生边界来预切对象,从而删除候选项。通过预处理,RCP可以在某些情况下以较高的精度降低带宽消耗和运行时间成本。此外,通过理论分析和计算机模拟的性能评估,我们表明所提出的算法可以减少带宽消耗。

Measurement of Managerial Performance Based on Two-Stage Relative Efficiency Method 基于两阶段相对效率法的管理绩效度量
Xu Yan-li, Feng Ying-jun
Two-stage relative efficiency model, a newly named analytical method, is presented here in order to measure managerial performance fairly. This method evaluates managerial performance by eliminating the influence of existing conditions. Empirical results show that managers in firms with relatively superior existing conditions still need to work hard to maintain their competitiveness and achieve better than before performance. On the other hand, managers in those firms with relatively inferior existing conditions can also achieve better than before performance and fair evaluation if they conscientiously make great efforts. The method presented here can avoid penalizing good managers who manage within an unfavorable existing condition as well as avoid rewarding poor managers who manage in a favorable existing condition. In a word, the two-stage relative efficiency model is an equitable and objective measuring method for efficiency.
为了公平地衡量管理绩效,本文提出了一种新的分析方法——两阶段相对效率模型。这种方法通过消除现有条件的影响来评价管理绩效。实证结果表明,在现有条件相对优越的企业中,管理者仍然需要努力保持竞争力,取得比以前更好的绩效。另一方面,在那些现有条件相对较差的企业中,管理者如果认真努力,也可以获得比以前更好的绩效和公平的评价。这里提出的方法可以避免惩罚在不利的现有条件下管理的优秀管理者,也可以避免奖励在有利的现有条件下管理的糟糕管理者。总而言之,两阶段相对效率模型是一种公平客观的效率度量方法。

Unsupervised Segmentation Method for Color Image Based on MRF 基于MRF的彩色图像无监督分割方法
Yimin Hou, Xiangmin Lun, W. Meng, Tao Liu, Xiaoli Sun
The paper proposes an unsupervised color image segmentation method based on Markov Random Field (MRF). The method involves intensity Euclidean Distance and spatial position information of the pixels in the neighborhood potential function of MRF. Therefore, the traditional potential function of MRF segmentation method is improved. Transforms the segmentation to a Maximum A Posteriori (MAP) problem which is solved by the Iterative Conditional Model (ICM). Uses the Fuzzy C-means to initialize the classification in the rang of specified class number. The optimal class number was chosen according to Minimum Message Length (MML) criterion to complete an unsupervised segmentation. In the experiments, synthetic and real images are used in the procedure and the results show that the proposed method is more effective than the classical methods.

Two Kinds of B-Spline-Type Trigonometric Curves 两种b样条型三角曲线
Lanlan Yan, Jiongfeng Liang
Two kinds of trigonometric spline bases are constructed in this paper. Based on these bases, two kinds of trigonometric spline curves are defined. As each piece of these trigonometric spline curves are generated by three consecutive control points, these curves retain many properties of the quadratic B-spline curves, but they have better continuity than the quadratic B-spline curves. For equidistant knots, they have continuity under normal conditions, and the second kind of curve has continuity under special conditions. Besides, these trigonometric spline curves are closer to the control polygon than the quadratic B-spline curves when the shape parameters under special conditions. In the last, the trigonometric spline surfaces with shape parameters are also constructed and they have most properties of the corresponding trigonometric spline curves.
本文构造了两类三角样条基。在此基础上,定义了两种三角样条曲线。由于每条三角样条曲线都是由三个连续的控制点生成的,因此这些曲线保留了二次b样条曲线的许多特性,但比二次b样条曲线具有更好的连续性。对于等距结点,在正常条件下具有连续性,而第二类曲线在特殊条件下具有连续性。此外,在特殊条件下,这些三角样条曲线比二次b样条曲线更接近控制多边形。最后,构造了具有形状参数的三角样条曲面,该曲面具有相应三角样条曲线的大部分性质。

Multilayer Anchor Alignment in AC-E Parallel Corpora of Chinese Tea Classics 中国茶经AC-E平行语料库的多层锚对齐
Jiang Yi, Jiang Xin, Wang Dapeng
Chinese tea literature has not made its appearance in the existing corpora. Bilingual corpus of ancient Chinese and English (AC-E) also wait to be extended for purposes such as CAT and designing educational software for Confucius Institutes all over the world. This paper aims at such a corpus by demonstrating multilayer anchor-points in improving the alignment accuracy in a bilingual parallel corpus of tea classics. An experiment is carried out with four layers of “anchor points”. Technical terms as the first layer are extracted with Term List of Winalign module in Trados. The second is register-specific words with 1:1 co-occurrence frequency in SL and TL. The third and fourth are composed respectively of proper nouns and transliterated Chinese-unique words. Statistics show that the alignment accuracy keeps increasing with the step-up of each layer. Since such anchor-points are typical in ancient Chinese classics, this method can be generalized in relevant fields.
中国茶文学在现有语料库中尚未出现。古中英文双语语料库(AC-E)也有待扩展,用于CAT和为世界各地的孔子学院设计教育软件。本文针对这样的语料库,展示了多层锚点在提高双语平行茶经语料库对齐精度方面的作用。用四层“锚点”进行了实验。技术术语作为第一层,使用Trados中的Winalign模块的Term List进行提取。第二种是语域特定词,在二语和外语中共现频率为1:1。第三种和第四种分别由专有名词和音译汉语特色词组成。统计表明,随着每一层的增加,对准精度不断提高。由于这种锚点在中国古代经典中具有典型性,因此该方法可以推广到相关领域。

Visual Simulation of the Temperature Field in the Ceramic Roller Kiln 陶瓷辊窑温度场的可视化仿真
Zhihua Wei, Paipai Chang, Wenbi Rao, Zhen Li
This paper has presented a numerical simulation method of the temperature field in the ceramic roller kiln. The method was that the model of firing zone with single-kiln was created by fluid dynamics software in which the standard k-ε turbulence model, DO radiation model and PDF combustion model were adopted. The model considered the size and structure of the kiln, the inlet and outlet status as the condition for simulation, and then the movement of the temperature field in kiln was showed clearly by the simulation data obtained. The results showed that such numerical simulation technology could save lots of costs, overcome the limitations of the actual measurement, and provide the guidance for the structure design of the ceramic roller kiln and the production of ceramics.
