略论贾宝玉和甄宝玉——兼论特殊典型化的艺术方法——矛盾分身术

“有两种精神居在我们心胸,一个想要同别一个分离。”甄贾（真假）宝玉是同一个人物思想矛盾的两个方面。这是一种很独特的塑造“矛盾人”的典型化方法。这种方法在现代的中外艺术中,已经很普遍了。曹氏写甄宝玉是用模糊法,高鹗则用了明朗法。这是倾向的不同。真假宝玉也是曹雪芹思想矛盾的某种反映。     

海洋水产养殖企业竞争力模糊综合评价

通过模糊评估法获得海洋水产养殖企业竞争力的各项指标,对其进行系统识别与归类,从盈利能力、管理能力、生产能力、产品优势、综合实力、发展能力六个方面构建海洋水产养殖企业竞争力评价指标体系,运用层次分析法确定各项指标的权重,并结合模糊数学方法建立海洋水产养殖企业模糊综合评价模型,提出依照评价分值将海洋水产养殖企业的竞争力分为低竞争力、较低竞争力、一般竞争力、较高竞争力和高竞争力五个等级。选择三家海洋水产养殖企业为实证样本,验证了海洋水产养殖企业竞争力的模糊综合评价方法。

Comparison between method of moments and entropy regularization algorithm applied to parameter estimation for mixed-Weibull distribution

Mixed-Weibull distribution has been used to model a wide range of failure data sets, and in many practical situations the number of components in a mixture model is unknown. Thus, the parameter estimation of a mixed-Weibull distribution is considered and the important issue of how to determine the number of components is discussed. Two approaches are proposed to solve this problem. One is the method of moments and the other is a regularization type of fuzzy clustering algorithm. Finally, numerical examples and two real data sets are given to illustrate the features of the proposed approaches.     

On three and four vicious walkers

We establish a reflection principle for three lattice walkers and use this principle to reduce the enumeration of configurations of three vicious walkers to the enumeration of configurations of two vicious walkers. More precisely, the reflection principle leads to a bijection between three walks (L₁, L₂, L₃) such that L₂ intersects both L₁ and L₃ and three walks (L₁, L₂, L₃) such that L₁ intersects L₃. Hence we find a combinatorial interpretation of the formula for the generating function for the number of configurations of three vicious walkers, originally derived by Bousquet-Mélou by using the kernel method, and independently by Gessel by using tableaux and symmetric functions. This answers a question posed by Gessel and Bousquet-Mélou. We also find a reflection principle for four vicious walks that leads to a combinatorial interpretation of a formula derived from Gessel's theorem.     

Counting strings at height j in Dyck paths

Let τ be an arbitrary lattice path, called in this context string, consisting of two kinds of steps (rises and falls) and let j be a non-negative integer.In this paper, the explicit formula for the generating function F_j associated with the Dyck path statistic “number of occurrences of τ at height j” is evaluated.For the expression of F_j some basic characteristics of the string are used, namely its number of rises, height, depth and periodicity, as well as the generating function of the Catalan numbers.     

基于模糊多属性决策的社区体育服务公众满意度测评研究

社区体育服务的发展水平作为城市文明程度和居民生活质量提高的标志,愈来愈受到人们的关注,社区体育服务公众满意度也日益成为了研究的焦点.结合满意度理论和我国社区体育服务的特色,引入基于期望值的模糊多属性决策方法构建了社区体育服务居民满意度测评体系,进行社区体育服务的满意度测评研究.综合考虑开展社区体育服务公众满意度评价的实际情况,采用三角模糊数得到带有定量指标和定性指标的区间型评价矩阵,并以实证研究验证该方法的合理性,从而为科学评价社区体育服务质量及公众满意度开辟一条新途径.
