簇程——一种大颗粒度的分布并发单元

开发了一个分布式操作系统的原型－ＣＬＵＳＴＥＲＳ，通过引入两级并发体制，提供了一种称为簇程（ｃｌｕｓｔｅｒ）的大颗粒度并发单元，初步的实践表明，簇程很好地适应了分布式系统对并发机制的独特要求。     

分布式系统中任务粒度和加速比关系

Algorithm of Intrusion Detection Based on Data Mining and Its Implementation

Intrusion detection is regarded as classification in data mining field. However instead of directly mining the classification rules, class association rules, which are then used to construct a classifier, are mined from audit logs. Some attributes in audit logs are important for detecting intrusion but their values are distributed skewedly. A relative support concept is proposed to deal with such situation. To mine class association rules effectively, an algorithms based on FP-tree is exploited. Experiment result proves that this method has better performance.

A High-accuracy Approach to Pronunciation Prediction for Out-of-vocabulary English Word

Letter-to-Sound conversion is one of the fundamental issues in text-to-speech synthesis. In this paper, we address an approach to automatic prediction of word pronunciation. This approach combines example-based learning and dynamic-programming searching to predict sub-word pronunciation. Word pronunciation is formed by concatenating sub-word pronunciations. We conducted comparative experiments over a large-scale English dictionary. Experimental results show that this approach can achieve accuracy of 70.1%, which outperforms those published results.

动态商品名称体系的建立

在分布式电子市场中，要提供一个推荐商品命名和分类体系作为市场参与方用来交易与通信的标准，为此，提出了一种中心推荐聚类算法。该算法能在生成的聚类中，根据异质属性的影响因子，确立具有代表意义的推荐概念及商品名称间的层次关系。通过收集分布式电子市场中不同参与方对商品命名和分类的信息，使用中心推荐聚类算法动态建立推荐商品名称体系。其中，商品名称体系包括商品的推荐命名、名称间的关系以及其定义。实验结果表明，该算法是可行的。     

双倍剂量生血宁片治疗慢性肾脏病3～4期肾性贫血的疗效观察

目的分析在慢性肾脏病3~4期肾性贫血患者治疗中,双倍剂量生血宁片的临床应用疗效。方法选取江西省九江市中医院于2014年2月至2015年2月收治的62例慢性肾脏病3~4期肾性贫血患者为研究对象,将其随机分为对照组与观察组,对照组患者服用常规剂量的生血宁片接受治疗,观察组患者则在对照组患者基础上服用双倍剂量生血宁片,对比两组患者的临床治疗效果及Hb、SF、TAST等指标情况。结果观察组患者的临床治疗效果明显好于对照组,主要生理指标改善情况也比对照组患者更为明显,两组患者数据经对比后差异具有统计学意义(P0.05)。结论在慢性肾脏病3~4期肾性贫血患者的治疗中,双倍剂量生血宁片的应用效果较好,值得推广应用。
