    Two major algorithmic tools associated with multiresolutional systems are discussed in this lecture: 1) "Multiresolutional Formation of the Motion Trajectory," and 2) "Synthesis of Possible Worlds". The first tool contains a family of niultiresolutional algorithms applicable for motion planning and control. It focuses upon imagining changes and is actively helpful for reasoning about actions. They... View full abstract»

    In this paper, a system that allows the connection of different types of sensors and sensor combinations is presented. The designed system is considered a black box from the point of view of the sensors, and provides the users with a multisensor fusion method to prove different sensor sets, which can be complementary and/or redundant, in order to save the users from creating a new structure for ea...

    Integral games of approach are considered in which the dynamics of a process under consideration is described by Volterra integral equations of second order with kernels having polar summable peculiarities. These games are connected naturally with the important class of model integral equations, solutions of which are expressed in terms of the generalized Mittag-Leffler function Eρ(...

    Summarizes results for a class of timed Petri nets called programmable timed Petri nets (PTPN) (Lemon et al., 1988). The application of results concerning the uniform ultimate boundedness of switched systems, modeled by PTPN, is discussed.

    Systemic semiotics, a combination of systemic functional linguistics and its elaboration into the general field of social semiotics, forms the basis for a new approach to the study of workpractices and information systems as patterns of human communication. Workpractices consist of one or more text-types referred to as genres, and zero or more actions-types. Action-types are purposeful, staged and... View full abstract»

    The Robot Sheepdog Project has developed a mobile robot that gathers a flock of ducks and manoeuvres them safely to a specified goal position. This is the first example of a robot system that exploits and controls an animal's behaviour to achieve a useful task. A potential-field model of flocking behaviour was constructed and used to aid the design of two novel flock-control methods. These methods... View full abstract»

    The 4D real-time control systems architecture (4D/RCS) defines a hierarchical decomposition for intelligent systems, with corresponding command and control pathways. In order to design the vehicle's behavior generation functions, we developed a set of task commands, goals, and actions that are organized hierarchically to form the basic vocabulary for planning and control of the vehicle.

    We consider stabilization of an affine in control, nonlinear autonomous hybrid dynamical system (HDS) plant model. HDS are systems that combine the dynamics of a discrete system abstractly modeled as an automaton and continuous system modeled as nonlinear ordinary differential equations. We drive a HDS version of exact linearization via nonlinear feedback. In doing so we were able to bypass the is... View full abstract»

    In a rather sharp departure from CL and AI approaches, modeling in computational semiotics (CS) neither presupposes rule-based or symbolic formats for linguistic knowledge representations, nor does it subscribe to the notion of symbolically represented world knowledge as some static structures that may be abstracted from and formatted independently of the way they are processed. Consequently, know... View full abstract»

  • Bottleneck analysis for self-adaption in multi-agent societies

    Publication Year: 1998, Page(s):446 - 451
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (708 KB)

    We describe an approach to achieve dynamic adaption of an artificial agent society to environmental changes. Such changes cause sub-optimalities in the agent society design, leading to overloaded or underloaded agents or agent groups in the society. Our approach provides a mechanism to reveal these sub-optimalities by integrating bottleneck analysis to structural self-adaption in a generic multi-a... View full abstract»
