Reversed preservation of stochastic orders for random minima and maxima with applications

In this paper, reversed preservation properties of right spread order, total time on test order and increasing convex (concave) order when taking random minima and maxima are developed. In this context, reversed preservation properties of some ageing concepts are investigated under parallel (series) systems which are composed of a random number of i.i.d. components. Some applications in reliability and economics are given.

个人主义的反思性文本--张爱玲《传奇》再探索

以个人主义为切入点,分析张爱玲的传奇文本,可以揭示张爱玲前期创作的人生况味和文化哲学内涵。在个人主义人生观的观照下,传奇文本通过"月亮"、"镜子"等意象的运用,人物形象精神性特质的勾勒以及独特的封闭式循环结构恰好指向反思。从语言哲学的角度看,传奇文本即可视为是竖在看 被看之间的一面镜子。它折射出自我意识对人性成长的重要作用以及反思只有在清醒自我意识的状态下,通过"镜子"作为参照系才能得以完成。传奇文本因而具有深邃的文化哲学内涵。

播出服务器磁盘I/O与缓存性能分析

针对电视台专业播出服务器在播出质量和播出性能上的高要求,提出了(s,S)策略下读数据缓存和复用缓存与节目数量、节目数据速率、磁盘性能、ASI卡缓存大小的关系。在此基础上进行的实验结果表明:分配给节目播出的读数据和复用缓存并不是越大越好,而是有一个较优的范围。据此可对服务器的资源分配进行优化。     

Quantitative Risk Assessment for Bovine Spongiform Encephalopathy in Low- or Zero-Prevalence Countries: The Example of Norway

A predictive case-cohort model is applied to Norwegian data to analyze the interaction between challenge and stability factors for bovine spongiform encephalopathy (BSE) during the period 1980-2010. For each year, the BSE risk in cattle is estimated as the expected number of cases. The age distribution of expected cases as well as the relative impact of different challenges is estimated. The model consists of a simple, transparent, and practical deterministic spreadsheet calculation model, in which the following country-specific inputs are entered: (i) annual imports of live cattle and meat and bone meal, (ii) age distribution of native cattle, and (iii) estimated annual basic reproduction ratio (R(0)) for BSE. Results for Norway indicate that the highest risk of BSE cases was in 1989, when a total BSE risk of 0.13 cases per year was expected. After that date, the year-to-year decrease in risk ranged between 3% and 47%, except for a secondary peak in 1994 at 0.06 cases per year. The primary peak was almost entirely (99%) attributable to the importation of 11 cattle from the United Kingdom between 1982 and 1986. The secondary peak, in 1994, originated mainly from the recycling of the U.K. imported cattle (92%). In 2006, the remaining risk was 0.0003 cases per year, or 0.001 per million cows per year, with a maximal age-specific incidence of 0.03 cases per million per year in 10-year-old cattle. Only 15% of the cases were expected in imported cattle. The probability of having zero cases in Norway in 2006 was estimated to be 99.97%. The model and results are compared to previous risk assessments of Norway by the EU.     

幽默语言弱关联因素分析

幽默语言在追求幽默交际中最佳关联同时,牺牲的却是语义、语境、逻辑最大关联。但是,在幽默交际中,如果说话者和听者能够互明幽默意图,如果听者能通过语境,利用自身的语言文化知识,能够实现幽默语言的最佳关联。
