A theory of intelligent systems
Proceedings. 5th IEEE International Symposium on Intelligent Control 1990, 1992The author proposes a theoretical model consisting of seven basic elements: actuators, sensors, sensory processing, world modeling, task decomposition, value judgment, and global memory/communications. These elements are integrated into a hierarchical system architecture wherein (a) control bandwidth decreases about an order of magnitude at each higher

Logic Journal of the IGPL, 2017
AbstractThis article introduces a new formal theory, the theory of $M$-system, which represents a many-valued logic system. Basic terms and concepts are defined which are the foundation for their further application. Though the theory comes from the field of electric circuitry, an attempt will be made to extend it to applications in linguistics.

INFORMAL SYSTEMS THINKING OR SYSTEMS THEORY
Cybernetics and Systems, 2003Systems thinking is the practice of holistic thinking, which can be informal or based on systems theory. Success has always depend on holistic rather than one-side thinking. Empirical findings about the innovative society can exemplify this statement, though there seems to be no universal agreement as to what the basic attributes of systems thinking ...

Information Systems, 1977
Abstract The overview presented covers a wide spectrum of aspects on information systems. Consequently, we had to be very brief and for detailed definitions and discussions we must refer the interested reader to the underlying literature. We have described how information systems present complex problems to their designers and we argued that it is ...

Systems Theory and the Anaesthetist
Acta Anaesthesiologica Scandinavica, 1980The application of the various aspects of systems theory has increased steadily over the last 10 years and has proved useful in such diverse fields as surgical services (Spratt et al. 1974), public health (Haas 1974), education (Harrington 1966), nephrology (Bigelow et al.

Systems Theory and Family Therapy: From a Critique on Systems Theory to a Theory on System Change
Contemporary Family Therapy, 1997Some system therapists reject the systemic view for various reasons, often related to violence, victimisation and power. This critique is based on an outdated narrow and incomplete knowledge of linear systems theory. A better understanding of these linear systems theories and of systems levels of organisation already answers much of the critique, but ...

Bulletin of Mathematical Biology, 1983
This is an investigation of natural systems from the standpoint of the mathematical theory of categories. It examines the relationships which exist between different descriptions through measurement of observables and dynamical interactions. We begin with a category theory of formal systems with observables, and then proceed to a category theory of ...

Thriving Systems Theory: An Emergent Information Systems Design Theory
2013 46th Hawaii International Conference on System Sciences, 2013Thriving Systems Theory is an emergent design quality framework encompassing both traditional objective metrics and the subjective, aesthetics. It draws theories of design quality in physical architecture originated by Christopher Alexander, the patriarch of design patterns, into the domain of models and information systems.

1976
Abstract : The two major research efforts were in the areas of (1) nonminimum-phase linear and nonlinear time-varying systems, and (2) multiple-loop single input-output systems. In both areas, the objective was to develop synthesis techniques to achieve assigned system performance specifications, despite significant uncertainty in a constrained part ...

Realization Theory of Nash Systems
SIAM Journal on Control and Optimization, 2009This paper deals with realization theory of so-called Nash systems, i.e., nonlinear systems the right-hand sides of which are defined by Nash functions. A Nash function is a semialgebraic analytic function. The class of Nash systems is an extension of the class of polynomial and rational systems and it is a subclass of analytic nonlinear systems.
