  • Knowledge-based approach to signal smoothing

    Publication Year: 1992, Page(s):23 - 28
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (448 KB)

    The task of signal smoothing is addressed as a special case of signal processing. Despite the fact that the smoothing methods are based on the analytic signal description and work on the quantitative representation of signals, good choice of a method is far from trivial and is based on the qualitative knowledge about the signal and noise. The authors aim is to help the usage of so called order sta... View full abstract»

  • A constraint maintenance system for the distributed resource allocation problem

    Publication Year: 1992, Page(s):197 - 202

    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»

    With the increase in the use of advanced technologies in products like aeroplanes and computers the performance of the cable harness has become critical. The cable harness needs to be designed as an integral part of the product and not as an after thought. The development cycle of the products has also shortened and there is an increased demand for a rapid design facility. The cable hardness desig... View full abstract»

  • A design methodology for a self-maintenance machine

    Publication Year: 1992, Page(s):179 - 184
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (364 KB)

    Traditional design for reliability is not perfect, because such systems aim at less faults but once a fault happens they hard-fail. To prevent such disasters, one should develop soft-fail machines that can still maintain their functions even if faults happen. The authors propose a framework of a self-maintenance machine (SMM). Two repair strategies are proposed; viz., control type and functional r... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (384 KB)

    A validation scheme has been developed to process aircraft flight data by coupling numerical and symbolic processing techniques. Feature interpretation and qualitative modelling approaches have been adopted since the observed, aircraft sensor network lacked instrumentation redundancy. The development of this application is presented in the context of a generic data reduction hierarchy for which im... View full abstract»

  • Automatic face recognition

    Publication Year: 1992, Page(s):29 - 34
    Cited by:  Papers (1)  |  Patents (7)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (364 KB)

    A review of competing facial recognition techniques is presented. The authors then go on to introduce a new method of feature-based facial codeing allowing an entire face to be represented in less than two hundred bytes of information. Crucial to this coding process is the use of an a priori model of the face, which helps to guide the location and storage of the most important facial parts. The da... View full abstract»

    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (392 KB)

    The authors describe a system, called Device Modeling Environment (DME), which facilitates both model formulation and simulation stages of modeling physical system behavior. There are three main stages in reasoning about the behavior of a system, namely (1) model formulation, (2) prediction, and (3) interpretation of the results. Close coupling of the three stages of reasoning about behavior will ... View full abstract»

  • Using qualitative bond graph reasoning to derive look-up tables for fuzzy logic controllers

    Publication Year: 1992, Page(s):226 - 231
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (300 KB)

    Qualitative reasoning, bond graphs and fuzzy logic are developed respectively in three different fields: computer science, system dynamics and automatic control. They all have their own strengths and weaknesses. Fortunately, these methods are compensating and they can be used to offset each other's weaknesses. Qualitative reasoning on bond graphs leads to ambiguities in its reasoning process while... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (376 KB)

    An architecture, Tilde (time-limited diagnostic environment) has been developed specifically to investigate time-constrained hierarchical diagnosis. Diagnosis is first performed at the most abstract level and is progressively deepened as time allows. Thus Tilde's objective is to find the most `profitable' search route through a hierarchical candidate space within a given deadline, the system has b... View full abstract»

  • A novel approach to finite automata with control application to transport systems

    Publication Year: 1992, Page(s):71 - 76
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (280 KB)

    The paper shows that finite automata are much closer related to discrete-time systems than assumed in the past. To this end a novel representation of Boolean functions is introduced similar to some sense to the canonical form of Shegalkin polynomials (1928). However common algebra is used instead of Boolean algebra. As a special class, systems which are linear in the sense of common algebra are co... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (288 KB)

    The authors suggest a new approach of target tracking by a robot. Robot joints are independently controlled. This research improves other research carried on decentralized control of automated systems in the Laboratory of Automatics and Computer Science of Marseille (LAIM) (Brun-Picard (1988), Carmona (1990). Previous research showed the feasibility of the decentralization of control algorithms. T... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (376 KB)

    The paper introduces a three dimensional simulation of multiple layer woven textile structures used for composite reinforcement. With the structural logic being delivered by an irregular 3D matrix, the images of most possible multiple layered structures can be generated. The simulation can be used to assist the design of reinforcements for composite materials, and the 3D images can be used as geom... View full abstract»

  • Qualitative modelling of dynamical systems for on-line diagnosis-knowledge acquisition vs. structured modelling

    Publication Year: 1992, Page(s):153 - 158
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (320 KB)

    The paper concerns the problem of finding qualitative models for a given dynamical system. It is shown that the principal modelling steps that are used in well-known modelling and identification methods in control theory can also be applied to qualitative modelling. This provides a systematic framework to find qualitative or even mixed quantitative-qualitative descriptions of dynamical systems View full abstract»

    Publication Year: 1992, Page(s):135 - 140
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (416 KB)

    The paper presents an object-oriented framework for the design of control systems that is based on the physical and functional structuring of the plant. The framework guides the designer from structuring the plant, over functional specification and design, to implementation. The basic units of the framework are objects that reside in states and are transferred between the states by means of state ... View full abstract»

    Network based (or distributed) systems are hard to design and understand, and correcting a design mistake will be very costly. These systems are further complicated by their real-time needs. The investigation is based on Fieldbus type networks which provide industrial local network communications via a bus which will interconnect to low cost devices such as transducers and controllers. Most applic... View full abstract»
