基于投入产出模型的中国对外贸易产品结构合理性研究

借鉴外贸商品结构合理度指数的思想,利用修正的影响力系数和感应度系数,构建出新的外贸产品结构合理度指数模型,并基于2002年、2005年和2007年的非竞争型投入产出数据,运用Matlab计量软件对中国42个产业部门进出口产品结构的合理性进行实证分析。研究结果发现:(1)总体上看,中国外贸产品结构在往更为合理的方向发展,且进口产品结构往更为合理方向演进的速度快于出口产品结构;(2)影响力系数与出口产品结构比重的排序并不完全匹配,表明出口产品结构亟需进一步调整优化,且应适量控制影响力系数较小而出口比重较大的产品额度,加强支柱产业出口产品比重;(3)感应度系数与进口产品结构比例的排序并不完全一致,说明进口产品结构亟待进一步调整和优化,且应适度缩小感应度系数小而进口比例较大的产品规模,增加瓶颈产业进口产品比例。

复杂工业设计产品外观轮廓合理性的模型研究

为了提高复杂工业产品外观轮廓的合理性,需要高精度设计。产品外观合理性检测需要对设计产品的弯曲率、倾斜角度等复杂属性形成关联性的阀值,才能形成是否合理的判断。传统的人工视觉方法应用到复杂工业设计产品外观轮廓合理性检测时,对一些复杂的扭曲度变化、角度的非正常偏移等特征很难形成完成的判断规则,会产生检测误差大等弊端。提出了采用关联视觉检测技术的复杂工业设计产品外观轮廓合理性检测的方法,根据小波包分析法对设计产品的外观图像轮廓尺度特征进行分析与提取,再运用像素分类判断矩阵对尺度变化的合理性进行判断,完成复杂工业设计产品外观轮廓合理性检测。仿真结果表明,利用计算机视觉检测复杂工业设计产品外观轮廓合理性,精准性高,鲁棒性强。

Development of a group support system to support collaborative works in value management workshops

Value Management (VM) is a rigorous and systematic approach to improve the value and optimise the overall cost of a facility. It identifies opportunities to remove unnecessary costs while assuring that quality, reliability, performance, and other critical factors will meet or exceed the customers’ expectations. It has been widely used in the construction industry in a number of countries. A recent survey, however, revealed several problems that hinder the wider use of this methodology in the industry. To overcome these problems, a feasibility study has been conducted to investigate whether or not a Group Support System (GSS) can support collaborative works in VM workshops. This paper introduces the development and structure of a prototype GSS which is designed to support the collaborative works of stakeholders in VM workshops. It begins with an introduction to the conceptual GSS framework and job plan, illustrating what GSS supports can be provided to VM workshops. This is followed by a detailed description of the GSS prototype system to demonstrate how these supports can be performed as an integrated computer system. The testing of the system is also discussed. The research findings provide strong evidence in supporting the notion of using GSS to improve VM implementation. The information support of GSS has been ranked to be the most useful GSS functions and most of the practitioners interviewed are highly interested in applying GSS to support VM workshops in the future.

Estimating antiwear properties of esters as potential lubricantbased oils using QSTR models with CoMFA and CoMSIA

Comparative molecular field analysis and comparative molecular similarity indices analysis were employed to analyze the antiwear properties of a series of 57 esters as potential lubricant-based oils. Predictive 3D-quantitative structure tribo-ability relationship models were established using the SYBYL multifit molecular alignment rule with a training set and a test set. The optimum models were all shown to be statistically significant with cross-validated coefficients q^2 > 0.5 and conventional coefficients r^2 > 0.9, indicating that the models are sufficiently reliable for activity prediction, and may be useful in the design of novel ester-based oils.

MOMENT-METHOD ESTIMATION BASED ON CENSORED SAMPLE

In reliability theory and survival analysis, the problem of point estimation based on the censored sample has been discussed in many literatures. However, most of them are focused on MLE, BLUE etc; little work has been done on the moment-method estimation in censoring case. To make the method of moment estimation systematic and unifiable, in this paper, the moment-method estimators(abbr. MEs) and modified momentmethod estimators(abbr. MMEs) of the parameters based on type Ⅰ and type Ⅱ censored samples are put forward involving mean residual lifetime. The strong consistency and other properties are proved. To be worth mentioning, in the exponential distribution,the proposed moment-method estimators are exactly MLEs. By a simulation study, in the view point of bias and mean square of error, we show that the MEs and MMEs are better than MLEs and the “pseudo complete sample” technique introduced in Whitten et al.(1988). And the superiority of the MEs is especially conspicuous, when the sample is heavily censored.
