摘要： Foodomics studies are normally concerned with multifactorial problems and it makes good sense to explore and to measure the same samples on complementary, synergistic analytical platforms that comprise multifactorial sensors and separation methods. However, the challenge of exploring, extracting and describing the data increases exponentially. Moreover, the risk of becoming flooded with non-informative data increases concomitantly. Acquisition of data from different analytical platforms provides opportunities for checking the validity of the data, comparing analytical platforms and ensuring proper data (pre)processing - all in the context of correlation studies. We provide practical and pragmatic tools to validate and to deal advantageously with data from more than one analytical platform. We emphasize the need for complementary correlation studies within and between blocks of data to ensure proper data handling, interpretation and dissemination. Correlation studies are a preliminary step prior to multivariate data analysis or as an introduction to more advanced multi-block methods. (C) 2014 Elsevier B.V. All rights reserved.

摘要： 本书在简要回顾基本C++程序设计概念的基础上，全面系统地介绍了队列、堆栈、树、图等基本数据结构。本书将C++语言作为数据结构的算法描述语言。一方面对传统的数据结构内容进行了C++语言实现，另一方面将数据结构与面向对象技术结合起来，围绕抽象数据类型的概念来讨论每一种数据结构及算法。书中大量C++语言的程序实例既是数据结构的具体实现，又是面向对象技术的算法基础。本书理论与实践并重，每章都有大量的习题，强调数据结构的应用价值。

关键词： 数学建模   课堂教学   关系  

摘要： 全国大学生数学建模竞赛已经成为我国面向大学生的一项非常重要的赛事活动,参加的高校数和学生数屡创新高。大赛创办的目的不仅仅是比赛,更重要的是通过比赛来激发学生的学习兴趣和创新能力的提高。因此,数学建模应该与平时的课堂教学和学习联系起来,使得学生能真正受益。该文详细阐述了"数据结构"课堂教学与数学建模的关系:数学建模能引领和促进课堂教学改革;同时,课堂教学能为数学建模提供必要的能力储备。

摘要： While many access control models have been proposed, little work has been done on the efficiency of access control systems. Because the access control sub-system of an Enterprise Content Management (ECM) system may be a bottleneck, we investigate the representation of permissions to improve its efficiency. Observing that there are many browsing-oriented permission request queries, we choose to implement a subject-oriented representation (i. e., maintaining a permission list for each subject). Additionally, we notice that with breadth- first ID numbering we may encounter many contiguous IDs under one object (e. g., folder). To optimize the efficiency taking into account the above two characteristics, this thesis presents a space-efficient data structure specifically tailored for representing permission lists in ECM systems. Besides the space efficiency, checking, granting or revocation of a permission is very fast using our data structure. It also supports fast union of two or more permission lists (determining the effective permissions inherited from users' groups). In addition, our data structure is scalable to support any increase in the number of objects and subjects. We evaluate our representation by comparing it against the bitmap based representation and a hash table based representation while using random ID numbering and breadth-first numbering, respectively. Our experimental tests on both synthetic and real-world data show that the hash table outperforms our representation for regular permission queries (i. e., querying permissions on a single object each time) as well as browsing-oriented queries with random ID numbering. However, our tests also show that 1) our representation supports faster browsing-oriented queries with breadth-first ID numbering applied while consuming only half the space when compared to the hash table based representation, and 2) our representation is much more space and time efficient than the bitmap based representation for our app
