通过实例验证,在熵损失函数下计算出的几何分布可靠度的多层Bayes估计是稳健的,并进一步表明在熵损失函数下计算出的几何分布可靠度的多层Bayes估计值比其在平方损失函数下算出的结果精度更高。

In this paper, fuzzy theory, Markov chain and RFM model are integrated to evaluate customer lifetime values. This approach calculates the profit contribution of customers in every purchasing situation. Firstly, customer purchasing state is updated contiguously by fuzzy theory and RFM model with transition matrix which represents the probabilities among purchasing states. Then the profit contribution of each period is computed by using revenue and cost data. Finally, the profit contribution of each customer is accumulated through some discounting consideration. This will construct the final customer lifetime values.

本研究结合模糊理论、马可夫链、和RFM(recency, frequency, monetary; RFM)模式,配合折现模式来计算顾客终身价值,其中模糊理论及RFM模型定义顾客之购买状态,马可夫链则推算顾客在每期购买状态改变的机率,然后推估出顾客在每期交易的转换机率,再结合产品的收益与成本资料,算出顾客在各期对公司的利润贡献,最后将各期的利润贡献折现加总,计算出各种购买状况下的顾客价值,利用此顾客价值就可指出哪些是对企业有利的顾客。

Mumps one pound, that is what I have put down, but I daresay it will be more like thirty shillings -- don't speak -- measles one five, German measles half a guinea, makes two fifteen six -- don't waggle your finger -- whooping-cough, say fifteen shillings -- and so on it went, and it added up differently each time; but at last Wendy just got through, with mumps reduced to twelve six, and the two kinds of measles treated as one.

After nest found, the dominating ecological factors with definite distance to nest tree (less than 10 meters) including tree species, tree height, habitat type of nesting-tree, nest position, the type of nesting tree branch, nest type, the type of nest-site, the viability status of tree and branch was described and measured. Geography coordinates (latitude-longitude) was converted into orthogonal coordinates, and add to Arcview3.2 as shape-file, and measured the distance between nest and the habitat type including double-line river, lake, seasonal lake, shallow mire, deep water mire, meadow mire, farmland, sparse forest, forest marsh, the boundary of Nature Reserve and road.

将调查所获得的东方白鹳巢址坐标转换成平面直角坐标,并将巢位点作为Arcview3.2中的矢量图层加入到已经矢量化的洪河保护区生境类型图中,运用Arcview3.2的距离量算功能,量算出每个巢距各生境类型的距离,包括双线河、湖泊、时令湖、轻沼泽、重沼泽、沼泽化草甸、旱田、疏林和森林沼泽,以及距保护区边界和公路的距离。

Finish to design the micro CNC, I have to investigate the adaptable parameters for cutting. This paper had calculated tool's radius, spindle's rotational speed, radial depth, and feed speed by the instantaneous cutting areas of the cutting forces model. To find out the instantaneous cutting areas by mathematica which can calculate the tangential, radial and axial component of cutting forces during cutting.
