控制与信息     
维纳(Wiener)是美国的数学家,他除了在数学上有很高的造诣外,还是一位兴趣十分广泛,知识渊博和思想活跃的著名学者。1948年,他的出色著作《控制论》的出版,标志着控制论这一新兴学科的诞生。《控制论》一书的副标题中,明确指出控制论的研究对象是动物和机器中的控制和通讯问题。著名控制论专家、英国生理学家艾什比(Ashby)在其《控制论导引》一书中认为控制论也确实可以定义为:它是研究这样一类系统的科学,在系统中能量是无关紧要的,而信息及控制却非常重要。同时,艾什比强调,控制论是研究复杂系统的,现在大规模的复杂生产…  相似文献

The landmark book of Hsue-Shen Tsien, ‘Engineering Cybernetics', gave birth 60 years ago to an engineering science of interrelations and synthetic behaviors. Clothing the bare bones of Norbert Wiener's conception of cybernetics, the book delineates for the new science the requirement(of having direct impacts on engineering applications), the aim(of encapsulating engineering principles and concepts), the problems(of analysis, design, and uncertainty), the tools(of basic and advanced mathematics), and the scope(systems that are single input and output or multiple input and output, linear or nonlinear, deterministic or stochastic).The book is a showcase of originality, critical thinking and foresights. In particular, the author calls into question the basic assumption that ‘the properties and characteristics of the system to be controlled were always assumed to be known' and points out that, in reality, ‘large unpredictable variations of the system properties may occur'. Sixty years later, the full spectrum of Tsien's prophetic ideas is yet to be fully grasped and engineering cybernetics, as Tsien envisioned, is still in the making.  相似文献

The Foundation for Legal Knowledge Systems (JURIX) has, sinceits foundation in 1988, become an internationally renowned forumfor Law and Artificial Intelligence in theNetherlands. This paper is based onan intellectual review of the work of JURIX requested by theorganisation as part of its 10th anniversary in December 1997 andpresented as a keynote address at the 10th anniversary conference.It has been updated to include the following two conferences. Itapplauds the overall effort but also suggests some directions forfuture development and suggests in particular: The breadth of research has been commendable, butthere is a need to move towards greater integration of systems andmigration to internet based systems. Tools are likely to be improved in the next generationincluding the internet. Legal Knowledge Based Systems (LKBS) researchmay need to abandon fine boundaries between AI and other applications tools. The commendable diversity of approaches to legalknowledge representation overlays concerns about the nature of lawand its translation in LKBS. These issues of knowledge representation, theory, costand organisation of production can be best addressed by a return to acybernetic systems theory as a basis of analysis of relationships involved,and an understanding of the implications of culture change. An awareness that traditional legal theories were notmeant for the information age. Theorisation about law needs to beinformed by a range of new theoretical approaches which approachlegal systems as cultural systems. There is need to study the impact on legal cultures ofthe development of knowledge based systems, that is the impact ofjurimetricisation of society.  相似文献

A new method of image restoration based on the quasi-solution method for a compact set of functions with bounded total variation is introduced. Application of this method does not require estimation of the noise level, which is necessary to choose the regularization parameter in the Tikhonov regularization method. The approbation of this method with test images shows its effectiveness for image deringing. The text was submitted by the authors in English. Andrey S. Krylov. Born 1956.
