大众高等教育时代的教学质量观

随着高等教育规模的不断扩张,中国已经进入了一个大众高等教育时代。在大众高等教育时代,大学教学质量观开始发生改变,主要表现在:第一,价值增值的质量观替代了传统的学术质量,价值增值的质量观重点关注学生在学业上的增量。第二,多样化的质量观替代统一的质量观,多样化的质量观与高等教育本身的多样性及分类发展等有着直接的关系。

A robust optimization approach to wind farm diversification

Wind farm diversification can smooth out the fluctuations in wind power generation and reduce the associated system balancing and reliability costs. Recent research has shown that wind farm diversification can be approached using mean–variance method. Traditional mean–variance wind farm diversification method is sensitive to the input data. To overcome the problem of lack of robustness, this paper proposes a novel wind farm diversification method based on robust optimization model. Under box and ellipsoidal uncertainty structures, the proposed robust optimization model can be formulated as a coupled problem composed of a linear programming problem and a conic quadratic programming problem. This model could be efficiently solved. Case studies are provided to demonstrate application of the model.

基于Kano模型的家庭成员通信需求的研究与设计

随着人民日益增长的数字化美好生活需要,家庭内部成员间的通信交流方式已从“单一”的语音通话向“多元化”的信息通信方式转变。目前家庭网主要提供成员间语音通话服务,已较难满足成员间视频化、社区化等多样化的通信需求。本文使用Kano模型针对家庭成员间的通信需求进行调研与分析,并将需求优先级排序转化为设计目标的重要程度,在满足用户需求的前提下,提升办理体验,同时为类似通信类产品研究与设计提供参考。     

A New Diagnosis Method Using Alarm Annunciation for Nuclear Power Plants

We discuss the methodology diversity for diagnosis reasoning in an autonomous operation system, and propose a new diagnosis method using an alarm annunciation system. The combination of annunciated alarms is expected to be peculiar to the anomalous phenomenon or accident. Moreover, as the state of affairs is developing, each appearance of the pattern is changing with time peculiarly to each anomaly or accident. The matter is utilized for the new diagnosis method. The patterns of annunciated alarms with progress of the events are prepared in advance under the condition of the anomalies or accidents by use of a plant simulator. The diagnostic reasoning can be done by comparing the obtained combination of annunciated alarms with the reference templates by using pattern matching method. On the other hand, we have another method, called COBWEB used for conceptual classification in cognitive science, to reason for diagnosis. We have carried out the experiments using the loop type LMFBR plant simulator to obtain the various combinations of annunciated alarms with progress of the events under the conditions of anomalies and accidents. The examined cases were related to the anomalies and accidents in the water/steam system of the LMFBR power plant. The simulation examination showed that each change of the pattern of annunciated alarms is specific to each anomaly or accident, and we have applied the pattern matching technique and COBWEB methods into the diagnostic reasoning using annunciated alarms. We could show the capability of these two methods to reason and focus among various candidates of causes of anomalies with gradually improved conviction degree as time passes from the occurrence of anomalies. It was also confirmed that these methods are effective in diagnosis reasoning as a way the operators are doing the diagnosis reasoning in existing plants.

从语言的三个层面——词汇层面、句法层面和语用层面来阐述语言多样化的表现。这三个平面相互制约共同规范着现实中人们使用语言的情况。通过列举人们日常生活中使用语言的事例，分析不同语言表达形式成因以及语言中形式和意义的关系，进而揭示语言形式多样化产生的机制。     

Technological Diversification Through Corporate Venture Capital Investments: Creating Various Options to Strengthen Dynamic Capabilities

Corporate venture capital (CVC) investment in technology-intensive entrepreneurial ventures has attracted increasing attention from established firms which recognize it as a useful learning investment strategy to create diversified technological options for future change. However, there is a lack of empirical research which examines the relationship between CVC investment and the corporate investors' technological diversification. In this study, we investigate the effects of CVC investments on corporate investors' technological diversity by using 20 years of panel data from corporate investors in five high-tech industries. As a result, we find that the total amount of CVC investments and the industrial diversity of portfolio companies exhibit curvilinear (inverted U-shape) relationships with the corporate investors' technological diversity. Moreover, the empirical results show that the absorptive capacity of corporate investors positively moderates the effects of CVC investments on the technological diversity.     

基于逆吊实验原理的空间结构形态数值创建方法

逆吊实验法是一种基于力学平衡原理的零弯矩结构形态创建方法,在结构形态学早期发挥了重要作用。为克服逆吊实验存在的模型相似律和测试精度等问题,提出一种将逆吊实验思想与数值模拟方法相结合的“数值逆吊法”,利用非线性有限元技术来实现逆吊结构形态的数值创建。该方法采用柔性索膜单元模拟逆吊结构,通过引入可变弹性模量技术并结合二分法实现对逆吊结构形状的精确控制。利用该方法对一逆吊实验模型进行数值模拟,并与试验结果进行比较,证明数值方法的精确性。在此基础上,通过调整各种约束条件研究了实现逆吊结构形态多样化的途径。利用所提方法对实际工程进行形态创建分析,证明了该方法在实际工程应用方面可行。
