New results on BIBO stability analysis for a class of neutral delay systems     

B. Wang  J. Wang  S.M. Zhong 《Journal of The Franklin Institute》2011,348(2):426-437

This paper studies bounded input bounded output (BIBO) stability for a class of neutral systems with time-varying delays. Based on Lyapunov method and linear matrix inequalities, some new BIBO stability criteria are established. The numerical simulation is made to demonstrate the effectiveness of the theoretical results obtained in this paper.  相似文献   

Effect of seasonality on the dynamical behavior of an ecological system with impulsive control strategy     

Hengguo Yu  Shouming Zhong  Syamal K. Sen 《Journal of The Franklin Institute》2011,348(4):652-670

In this paper, on the basis of the theories and methods of ecology and ordinary differential equation, an ecological model consisting of two preys and one predator with impulsive control strategy and seasonal effects is established. Conditions which guarantee the global asymptotical stability of the prey-eradication periodic solution are obtained using the theory of impulsive equations, small amplitude perturbation skills, and comparison techniques. Further, the influences of the impulsive perturbation and seasonal effects on the inherent oscillation are studied numerically. These show to be consistent with the theoretical analysis and rich complex population dynamics, such as species extinction and permanence. Moreover, the population dynamical behavior of the model is demonstrated by the computed largest Lyapunov exponent. By investigating the strange attractors through their computed Fourier spectra, we know that seasonality has a profound effect on the population dynamical behavior. All these results are expected to be of use in the study of dynamic complexity of ecosystems.  相似文献   

中共90年来领导人民抗灾救灾的经验研究     

刘钊  王亚非 《绵阳师范学院学报》2011,30(7):92-96,137

我国是一个自然灾害频繁而又严重的国家,中国共产党从成立至今,领导人民群众抗灾救灾也一直没有停止过,其中基层党组织在抗灾救灾中始终发挥着战斗堡垒作用,并且积累了丰富的经验。本文在对90年来基层党组织抗灾救灾的经验进行分析梳理的基础上,从指导思想、根本方法、组织模式、内在动力、制度保障等方面对经验分别进行了归纳总结。  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   

The state of play of blockchain technology in the financial services sector: A systematic literature review     

《International Journal of Information Management》2020

The modern trends of digitalization have completely transformed and reshaped business practices, whole businesses, and even a number of industries. Blockchain technology is believed to be the latest advancement in industries such as the financial sector, where trust is of prime significance. Blockchain technology is a decentralized and coded security system which provides the capability for new digital services and platforms to be created through this emerging technology. This research presents a systematic review of scholarly articles on blockchain technology in the financial sector. We commenced by considering 227 articles and subsequently filtered this list down to 87 articles. From this, we present a classification framework that has three dimensions: blockchain-enabled financial benefits, challenges, and functionality. This research identifies implications for future research and practice within the blockchain paradigm.  相似文献
