    The problem of allocating resources to activities may be decomposed into sub-problems, and these sub-problems may in turn be distributed across a society of problem-solving agents. Distribution may be due to the geographical nature of the problem, or may reflect the structure of the organisation within which the activities take place. However, one might anticipate some degree of coupling between s... View full abstract»

    Compares fuzzy and Kalman-filter control systems for real-time target tracking. Both systems performed well in the presence of additive measurement noise. In the presence of mild process (unmodelled-effects) noise, the fuzzy system exhibited finer control. The authors tested the robustness of the fuzzy controller by removing random subsets of fuzzy associations or `rules', and by adding destructiv... View full abstract»

  • Performance of a neuro-model-based robot controller: adaptability and noise rejection

    Effective control strategies for robotic manipulators usually require the on-line computation of the robot dynamic model in real time. However, the complexity of the robot dynamic model makes this difficult to achieve in practice, and multiprocessor controller architectures appear attractive for real-time implementation inside the control servo loop. Furthermore, inevitable modelling errors, chang... View full abstract»

  • Knowledge-based approach to signal smoothing

    Publication Year: 1992 , Page(s): 63 - 75

    The analytic approach to signal processing performs well if there is adequate understanding of the characteristics of the signal source. In more complicated cases, syntactic signal processing tools used to be a working alternative; however, these share the common algorithmic background with the numerical methods. On the other hand, the filed area of order statistics (OS) introduced into signal pro... View full abstract»

    Easel, is a smart CAD package which attempts to analyse and tidy up sketches as a designer draws them. This paper presents an overview of the system, details of its user interface and the curve-fitting approach. The main part of the paper is concerned with automatic methods to infer and enforce geometric relations intended by the user. The authors also discuss their conclusions as regards performa...

  • Qualitative modelling of continuous-variable systems by means of nondeterministic automata

    Considers the problem of qualitative modelling of discrete-time continuous-variable dynamical systems, for which only a quantised measurement [x(k)] of the state x(k) is available. The qualitative model has to describe the qualitative trajectory x(1), x(2),. . . for given qualitative initial state x(0) and qualitative input sequence. First, it is shown that the qualitative trajec... View full abstract»
