南坪中心交通枢纽工程的地下室防水设计

本文介绍了南坪中心交通枢纽工程的防水设计,该项目所面临的难题是:作为使用年限为一百年的地下建筑,目前没有任何一种防水材料的使用寿命与之相匹配。本枢纽工程的地下室防水设计考虑了外包防水层、变形缝防水和施工缝防水等地下工程的常用做法,并结合工程的特点,采用了切实可行的设计及施工方案;还考虑到渗漏修补的预留措施,包括外包防水卷材的修补、化学浆液加固、内防水与内排水的预留等。     

Analysis of the peculiarity of the japanese software development style in offshore software development

Offshore software development (OSD) is now becoming a global trend. While western companies are using OSD effectively, Japanese companies have not yet used it effectively. Several studies have concluded that this is due to the peculiarity of the Japanese software development style in OSD and have pointed out the problems of Japanese OSD. However, the peculiarity of the Japanese software development style has not been identified yet. Therefore, this paper attempts to identify it. Most previous studies have described the problems of Japanese OSD without considering the software development method. We have focused on agile methods and attempted to analyze the problems pointed out previous studies in accordance with the features of agile methods. It was found that the Japanese software development style is agile‐like. In addition, a survey was conducted to find out what kind of software development method is being used in Japanese OSD projects. It was found that the waterfall method is mainly used. It is concluded that the peculiarity of the Japanese software development style and problems come from the conflict between the software development methods used and their actual implementations.

面向移动云存储的属性基解密服务中间件

属性基加密（ABE）算法支持对云端数据的细粒度访问控制。针对属性基解密计算复杂度高,难以在资源受限的移动终端上实现的问题,提出并实现了一种面向移动云存储的属性基解密服务中间件。在保证密文信息不被中间件获取的前提下,中间件为移动终端代理属性基解密服务,实现了基于树形结构的线性秘密共享（LSSS）矩阵求解,降低了终端的计算与通信开销,提高了解密速度;属性权威可以在不需要用户参与的条件下,即时、细粒度地撤销用户属性;所有接口均使用Restful服务,保证了通用性。实验结果表明,属性基解密服务中间件提高移动设备解密性能近30倍,具备较好的并发性能,属性撤销具有实用性。     

安全可验证的行列式云外包计算及其电子交易方案

针对现有的云外包计算协议中服务端可能存在的用户信息被泄露、篡改等问题,提出了一个云环境下的安全、高效、可验证的矩阵行列式外包计算协议。首先,基于矩阵模糊技术构造云外包计算协议,它能够在不需要任何困难性假设的前提下保证用户信息的安全性;其次,通过构造一类特殊的变换矩阵对明文矩阵进行处理,使用户在收到返还结果后,能有效验证所反馈的计算结果是否被篡改,性能分析表明,此协议可以有效提高云外包计算的效率;最后,给出一个行列式外包计算的电子交易框架,能够有效应用于电子商务等领域。     

云外包服务提供商竞争力评价研究

Sourcing Knowledge and Innovation in a Low-Technology Industry

This paper investigates the relationship between knowledge sourcing and innovation in a select low- to medium-technology industry, the forest sector. It is based on data from the Statistics Canada Survey of Innovation 2005. Econometric models are developed and tested, specifically logistic regression analyses, in order to probe the relationship between select forms of embodied and disembodied knowledge and levels of innovation intensity. Differences between single establishment Canadian firms, multi-establishment Canadian firms, Canada–USA multi-establishment firms and establishments belonging to multinational firms are studied in terms of the relationship between innovation and sources of knowledge. Findings indicate that establishment innovative performance is related to knowledge sourcing strategies and furthermore that organization ownership/structure impacts significantly upon this relationship.
