Bibliometric maps of field of science   总被引：2，自引：1，他引：2  

Irina Marshakova-Shaikevich 《Information processing & management》2005,41(6):1534-1547

The present paper is devoted to two directions in algorithmic classificatory procedures: the journal co-citation analysis as an example of citation networks and lexical analysis of keywords in the titles and texts. What is common to those approaches is the general idea of normalization of deviations of the observed data from the mathematical expectation. The application of the same formula leads to discovery of statistically significant links between objects (journals in one case, keywords — in the other). The results of the journal co-citation analysis are reflected in tables and map for field “Women’s Studies” and for field “Information Science and Library Science”. An experimental attempt at establishing textual links between words was carried out on two samples from SSCI Data base: (1) EDUCATION and (2) ETHICS. The EDUCATION file included 2180 documents (of which 751 had abstracts); the ETHICS file included 807 documents (289 abstracts). Some examples of the results of this pilot study are given in tabular form . The binary links between words discovered in this way may form triplets or other groups with more than two member words.  相似文献   

Stability and dissipative analysis for a class of stochastic system with time-delay     

Hao Zhang  Huaicheng Yan 《Journal of The Franklin Institute》2010,347(5):882-3355

This paper deals with the stability and dissipative problem of a class of stochastic hybrid system. The system under study involves Markovian jump, impulsive effects and time delay, which are often encountered in practice and are the sources of instability. Our attention is focused on analysis of whether the stochastic hybrid system with time-delay is stochastically asymptotically stable and strictly (Q, S, R) dissipative. By introducing an extra artificial time instance, the equivalent system is obtained and the sufficient conditions are derived by using linear matrix inequality (LMI) techniques. The main results of this paper unify the existing results on H_∞ control.  相似文献   

Design of a fast real-time LPV model predictive control system for semi-active suspension control of a full vehicle     

Marcelo Menezes Morato  Manh Quan Nguyen  Olivier Sename  Luc Dugard 《Journal of The Franklin Institute》2019,356(3):1196-1224

This article is concerned with the control of a Semi-Active suspension system of a 7DOF Full Vehicle model, equipped with four Electro Rheological (ER) dampers, taking into account their incipient dissipativity constraints. Herein, a real-time, fast, advanced control structure is presented within the Model Predictive Control framework for Linear Parameter Varying (LPV) systems. The control algorithm is developed to provide a suitable trade-off between comfort and handling performances of the vehicle in a very limited sampling period ($T_s=5\text{ms}$), in view of a possible realtime implementation on a real vehicle. The control structure is tested and compared to other standard fast control approaches. Full nonlinear realistic simulation results illustrate the overall good operation and behaviour of the proposed control approach.  相似文献   

Patenting and US academic research in the 20th century: The world before and after Bayh-Dole   总被引：2，自引：0，他引：2  

Bhaven N. Sampat 《Research Policy》2006,35(6):772-789

The dramatic growth of patenting and licensing of publicly funded research by American research universities in the closing quarter of the 20th century has stimulated some of the highest-profile debates in science and technology policy today. The issue of what aspects of academic research should be public - and what private - lies at the heart of each of these debates. The movement of academic scientists into commercialisation of discoveries and inventions has been extolled by some as a new model of academic research, one which facilitates economic and social returns from universities. At the same time, this trend has been criticised by others as representing a socially inefficient ‘privatisation’ of academic research and as a threat to the ethos of science itself. This paper places these debates in historical context, with a review of changes in American universities’ patenting policies, procedures and practices throughout the 20th century, an assessment of the logic underlying the passage of the Bayh-Dole Act of 1980, and an overview of its effects on economic returns from university research.  相似文献

智慧城市建设模式选择研究     

朱宗乾  贾义伍 《未来与发展》2016,(6)

为指导城市管理者对智慧城市建设模式进行理性选择,从智慧城市建设模式和建设环境相匹配的视角,构建了建设模式选择指标体系,分别对当前常见的5种智慧城市建设模式和城市建设环境进行评价。然后运用改进的TOPSIS 法对建设模式和建设环境之间的匹配度进行了建模分析,解决了传统TOPSIS 法中备选模式与正负理想解可能存在的距离同向性问题。研究结论中得到的垂直距离越小则表明该模式越优,即该智慧城市建设模式与该城市的建设环境越为匹配。  相似文献
