Statistical inference of Marshall-Olkin bivariate Weibull distribution with three shocks based on progressive interval censored data

There are several failure modes may cause system failed in reliability and survival analysis. It is usually assumed that the causes of failure modes are independent each other, though this assumption does not always hold. Dependent competing risks modes from Marshall-Olkin bivariate Weibull distribution under Type-I progressive interval censoring scheme are considered in this paper. We derive the maximum likelihood function, the maximum likelihood estimates, the 95% Bootstrap confidence intervals and the 95% coverage percentages of the parameters when shape parameter is known, and EM algorithm is applied when shape parameter is unknown. The Monte-Carlo simulation is given to illustrate the theoretical analysis and the effects of parameters estimates under different sample sizes. Finally, a data set has been analyzed for illustrative purposes.     

Newly deterministic construction of compressed sensing matrices via singular linear spaces over finite fields

A valuable opportunity is provided by compressed sensing (CS) to accomplish the tasks of high speed sampling, the transmission of large volumes of data, and storage in signal processing. To some extent, CS has brought tremendous changes in the information technologies that we use in our daily lives. However, the construction of compressed sensing matrices still can pose substantial problems. In this paper, we provide a kind of deterministic construction of sensing matrices based on singular linear spaces over finite fields. In particular, by choosing appropriate parameters, we constructed binary sensing matrices that are superior to existing matrices, and they outperform DeVore’s matrices. In addition, we used an embedding manipulation to merge our binary matrices with matrices that had low coherence, thereby improving such matrices. Compared with the quintessential binary matrices, the improved matrices possess better ability to compress and recover signals. The favorable performance of our binary and improved matrices was demonstrated by numerical simulations.

改革开放以来欧盟国家中的中国大陆新移民

华人移居欧洲的历史悠久,但华人在真正意义上作为移民族群生活于欧洲始于近代,迄今仅有100多年的历史.1978年中国改革开放前,欧洲的华人主要有广东人、浙江人、香港人和东南亚华裔难民.早期欧洲华侨华人社会中占主导地位的是浙江人和广东人.浙江人是最早进入欧洲的华人之一,在欧洲的一些城市里贩卖一种叫"青田石"的石雕制品,他们有着很强的自谋生路的能力,是欧洲华侨华人社会中最持久也最有韧性的一支.

谈城阳方言儿化和普通话去声分归阴平、阳平的问题

青岛城阳方言属于胶辽官话，其语音系统有鲜明的特点：分尖团音，韵母简化，声调三个。除此之外，城阳方言有两个比较特殊的语言现象：儿化和普通话的去声字在城阳方言分别归阴平、阳平，前者会对音节的声母、韵母都产生比较特殊的影响；后者则和城阳方言本身只有三个声调以及语法条件的限制有关。     

国内主要城市文化产业模式比较研究

文化产业是21世纪的朝阳产业。本文通过对我国各地区文化产业发展状况的分析,发现各地文化产业的模式开始从模仿性、随从性向自主型、特色型转变,形成了一些具有地域特色的发展模式雏型,如创意整合型的北京模式,市场拉动型上海、深圳模式,品牌扩张型的西安、成都模式和品牌胜出型的长沙模式。     

罗马法复兴与西欧法制现代化

罗马法在很大程度上影响了西欧法制现代化的进程。首先 ,罗马法的法典化倾向与现代西欧的法律创制之间存在着承继关系 ;其次 ,罗马法蕴涵的法律权威与权利观念受到了近现代西欧的推崇与接纳 ;再次 ,罗马法的理性光芒为近现代西欧学者所效仿 ,甚至在当代的欧盟法院中罗马法仍然不乏用武之地
