Fuzzy sliding mode control design for a class of disturbed systems     

Bo Wang  Peng Shi  Hamid Reza Karimi 《Journal of The Franklin Institute》2014

This paper discusses the problem of the fuzzy sliding mode control for a class of disturbed systems. First, a fuzzy auxiliary controller is constructed based on a feedback signal not only to estimate the unknown control term, but also participates in the sliding mode control due to the fuzzy rule employed. Then, we extend our theory into the cases, where some kind of system information can not be obtained, for better use of our theoretical results in real engineering. Finally, some typical numerical examples are included to demonstrate the effectiveness and advantage of the designed sliding mode controller.  相似文献

Predicting citation counts based on deep neural network learning techniques     

《Journal of Informetrics》2019,13(2):485-499

With the growing number of published scientific papers world-wide, the need to evaluation and quality assessment methods for research papers is increasing. Scientific fields such as scientometrics, informetrics, and bibliometrics establish quantified analysis methods and measurements for evaluating scientific papers. In this area, an important problem is to predict the future influence of a published paper. Particularly, early discrimination between influential papers and insignificant papers may find important applications. In this regard, one of the most important metrics is the number of citations to the paper, since this metric is widely utilized in the evaluation of scientific publications and moreover, it serves as the basis for many other metrics such as h-index. In this paper, we propose a novel method for predicting long-term citations of a paper based on the number of its citations in the first few years after publication. In order to train a citation count prediction model, we employed artificial neural network which is a powerful machine learning tool with recently growing applications in many domains including image and text processing. The empirical experiments show that our proposed method outperforms state-of-the-art methods with respect to the prediction accuracy in both yearly and total prediction of the number of citations.  相似文献   

When research assessment exercises leave room for opportunistic behavior by the subjects under evaluation     

《Journal of Informetrics》2019,13(3):830-840

This study inserts in the stream of research on the perverse effects that PBRF systems can induce in the subjects evaluated. The authors’ opinion is that more often than not, it is the doubtful scientific basis of the evaluation criteria that leave room for opportunistic behaviors. The work examines the 2004–2010 Italian national research assessment (VQR) to test the lack of possible opportunistic behavior by universities in order to limit the penalization of their performance (and funding) due to the presence of scientifically unproductive professors in faculty. In particular, institutions may have favored “gift authorship” practices. The analysis thus focuses on the output of professors who were unproductive in the VQR publication window, but became productive (“new productives”) in the following five years. A number of universities show a higher than average share of publications by new productives that are in co-authorship exclusively with colleagues from the same university. Although this might be thought to reflect opportunistic behavior by universities, the empirical evidence does not support this assumption.  相似文献   

Google scholar对文摘数据库的冲击     

张宇娥  刘静  李世兰 《四川图书馆学报》2011,(3):60-62

文摘数据库以其收录信息全、检索功能强、全文链接、定题跟踪等优势,被图书馆界公认为是系统检索科研信息的首选检索工具,但科研人员却更多地选择Google scholar。文章从信息来源、检索功能等方面对比Googlescholar与文摘数据库,认为文摘数据库仍是系统检索科研信息的首选检索工具,提出通过加强宣传文摘数据库、完善馆藏链接与全文链接、整合电子资源等方式,使更多的科研人员选择文摘数据库。  相似文献
