论网络赌球活动的危害及其现存的法律问题

运用文献资料法等研究方法,对我国网络赌球活动的特点、发展及其危害进行了分析,研究认为：相关法律法规的不完善是我国治理赌球活动所凸显出来的一个重要问题,主要表现在电子证据的合法性与易销毁问题、管辖权的归属问题与调查取证问题、网络赌球犯罪的主观认定等多个方面,建议：尽早制定和出台防控赌球活动的法律法规,完善法律体系,同时,一方面在国际上要加强司法合作,另一方面在国内要强化多部门协同执法意识,齐抓共管,才能够有效的遏制网络赌球行为。     

Using the Dempster-Shafer Theory of Evidence to Rank Documents

Multi-source information can be utilized collaboratively to improve the performance of information retrieval. To make full use of the document and collection information, this paper introduces a new information retrieval model that relies on the Dempster-Shafer theory of evidence. Each query-document pair is taken as a piece of evidence for the relevance between a document and a query. The evidence is combined using Dempster’s rule of combination, and the belief committed to the relevance is obtained. Retrieved documents are then ranked according to the belief committed to the relevance. Several basic probability assignments are also proposed. Extensive experiments over the Text REtrieval Conference (TREC) test collection ClueWeb09 show that the proposed model provides performance similar to that of the Vector Space Model (VSM). Under certain probability assignments, the proposed model outperforms the VSM by 63% in terms of mean average precision.     

红楼纪年审计报告

《红楼梦》有三个模糊不清:故事的年代模糊不清,人物的年龄模糊不清,故事的地点模糊不清。本报告是对《红楼梦》故事的年代进行的专项审计,文章的独特之处是:揭开这些模糊不清的秘密,不是依靠复杂繁琐的史实考证和史料考证,而主要从《红楼梦》的文字叙述来寻找依据,进行逻辑推理和演绎推算;文章的基本内容是:红楼纪年的命名和时间,各个红楼年代的文章结构、审定证据和重要事件。     

一种基于证据决策的航迹相关算法

基于证据决策的思想,对传统的最近领域法(NN)及K近领域法(K-NN)进行改造,设计新的航迹相关判决准则,提出一种新的分布式多传感器航迹关联算法(EK-NN). 通过仿真试验分析,并与最近领域法(NN)及K近领域法(K-NN)进行比较. 结果表明,在密集目标环境下,基于证据决策的(EK-NN)航迹关联算法明显优于最近领域法(NN),较K近领域法(K-NN)也有一定的改进.

Multi-sources information fusion algorithm in airborne detection systems

To aim at the multimode character of the data from the airplane detecting system, the paper combines Dempster- Shafer evidence theory and subjective Bayesian algorithm and makes to propose a mixed structure multimode data fusion algorithm. The algorithm adopts a prorated algorithm relate to the incertitude evaluation to convert the probability evaluation into the precognition probability in an identity frame, and ensures the adaptability of different data from different source to the mixed system. To guarantee real time fusion, a combination of time domain fusion and space domain fusion is established, this not only assure the fusion of data chain in different time of the same sensor, but also the data fusion from different sensors distributed in different platforms and the data fusion among different modes. The feasibility and practicability are approved through computer simulation.     

新不确定度量下的冲突证据融合

针对证据高度冲突的情况下,DS证据理论在实际应用中出现错误融合结果的问题,提出基于不确定度的冲突解决方法.首先分析现有的不确定度量方法的不足,研究基本概率赋值本身所包含的信息,提出一种新的对证据不确定性度量的方法;依据新的不确定度量,结合证据距离生成权重来修正待组合证据体,再利用Dempster规则完成证据组合,可有效解决证据高度冲突情况下的信息融合问题,最后通过算例验证了该方法的有效性.     

基于粗糙集和证据理论的设备状态评估方法

为准确判定复杂设备健康状态，提出一种基于粗糙集理论和证据理论的健康状态评估方法。鉴于粗糙集只能处理离散指标，首先提出一种基于动态模糊C-均值聚类算法的连续型评估指标的离散化方法；再通过基于互信息的属性约简算法对复杂设备健康状态评估指标进行约简；然后对约简的评估决策表进行处理，构建基本信度分配函数；最后利用D-S合成规则进行多指标合成得到健康状态，进一步挖掘评估指标与健康状态间的关系。实例研究及对比分析表明该方法能有效提高决策可信度，减少评估的不确定性。
