软硬件协同设计复杂问题的计算模型和算法(英文)

软硬件划分是设计复杂嵌入式系统的关键环节。论文综述了近年来提出的解决软硬件划分问题的计算模型和相应算法。软硬件划分问题可以建模成各种限定不同约束条件的背包问题模型,同时需要考虑任务块间的通信消耗。背包问题中的子项相当于软硬件划分问题中的任务块。论文针对不同的计算模型,介绍了相应的精确算法和启发式算法。论文最后探讨了若干待研究的潜在问题。

碧梧翠竹 以类相从——桐竹关系考论

梧桐与竹分别为凤凰的栖止之所与食物。桐、竹在现实应用、文化生活等方面都有着更为广泛的并联。桐、竹是弦乐与管乐的代称;桐孙、竹孙是生殖崇拜之物;桐杖、竹杖是母丧、父丧所持之杖;梧、竹是祝寿词中的常见意象。桐竹是＂比德＂意象,具有风神俊朗、节操高直的复合内涵,体现出＂清＂、＂贞＂和合的特点。元代以后,梧竹成为绘画的重要题材,体现文人的笔墨意趣、人格襟怀。宋代以后,梧竹是私家园林的常见景点,其清幽之境是文人对俗世的对抗与超越。梧竹不仅是文学意象,也是文化符号。     

Project risk management using multiple criteria decision-making technique and decision tree analysis: a case study of Indian oil refinery

This study proposes an integrated analytical framework for effective management of project risks using combined multiple criteria decision-making technique and decision tree analysis. First, a conceptual risk management model was developed through thorough literature review. The model was then applied through action research on a petroleum oil refinery construction project in the Central part of India in order to demonstrate its effectiveness. Oil refinery construction projects are risky because of technical complexity, resource unavailability, involvement of many stakeholders and strict environmental requirements. Although project risk management has been researched extensively, practical and easily adoptable framework is missing. In the proposed framework, risks are identified using cause and effect diagram, analysed using the analytic hierarchy process and responses are developed using the risk map. Additionally, decision tree analysis allows modelling various options for risk response development and optimises selection of risk mitigating strategy. The proposed risk management framework could be easily adopted and applied in any project and integrated with other project management knowledge areas.     

Case study in Six Sigma methodology: manufacturing quality improvement and guidance for managers

This article discusses the successful implementation of Six Sigma methodology in a high precision and critical process in the manufacture of automotive products. The Six Sigma define–measure–analyse–improve–control approach resulted in a reduction of tolerance-related problems and improved the first pass yield from 85% to 99.4%. Data were collected on all possible causes and regression analysis, hypothesis testing, Taguchi methods, classification and regression tree, etc. were used to analyse the data and draw conclusions. Implementation of Six Sigma methodology had a significant financial impact on the profitability of the company. An approximate saving of US$70,000 per annum was reported, which is in addition to the customer-facing benefits of improved quality on returns and sales. The project also had the benefit of allowing the company to learn useful messages that will guide future Six Sigma activities.     

港口与腹地关系研究综述

在后金融危机时代,中国港口业供大于求的矛盾将日益凸显,对腹地货源的争夺将日趋激烈,对港口与腹地关系的研究进行综述不仅可以清晰地勾勒出港口业发展的历程和竞争模式的转变,而且对港口腹地隶属度问题最新进展的分析,对疏运网络的优化、港口的定位和布局规划以及港口群间竞合关系的确定等提供理论依据和参考。本文以物流领域的港口与腹地关系这一基础应用问题为研究对象,对港口腹地隶属关系划分方法的发展历程和研究现状进行了综述,对各划分方法的特点进行了比较总结,并对该领域的研究热点和方向进行了展望。

TIMSS试题的机器翻译系统构建及其效果

研究以范例为基础的机器翻译技术和英汉双语对应的结构辅助英汉单句语料的翻译。翻译范例是运用一种特殊的结构,此结构包含来源句的剖析树、目标句的字符串、以及目标句和来源句词汇对应关系。将翻译范例建立数据库,以提供来源句作词序交换的依据,最后透过字典翻译,以及利用统计式中英词汇对列和语言模型来选词,产生建议的翻译。研究是以2010年国际数学与科学教育成就趋势调查测验试题为主要翻译的对象,以期提升翻译的一致性和效率。以NIST和BLEU的评比方式,来评估和比较在线翻译系统和本系统所达成的翻译质量。
