    The design of an integrated control system using stabilising fins and the rudder for ship roll stabilisation is discussed. Following the description of the mathematical models of typical warship dynamics and wave disturbances, controller designs based on traditional sensitivity analysis in the frequency domain are presented. Simulation results are used to demonstrate the enhanced roll stabilisation which can be achieved by the adoption of the proposed integrated control strategy View full abstract»

    Analysis guidelines have been developed which are based on experience gained in using the finite-element method closely linked with the design process. This insight into day-to-day problems is aimed at helping engineers faced with the decision process at the start of a design project View full abstract»

    A PC-based instrumentation system developed primarily to diagnose Huntington's disease, Parkinson's disease and schizophrenia by using the contingent negative variation (CNV) of the subject's electroencephalogram (electrical activity of the brain) is described. The system is capable of controlling the required experiment, acquiring and processing the signals from eight channels, and generating the diagnosis results. As the diagnosis was based on a signal (i.e. the CNV) which has an amplitude typically of the order of a few microvolts and is usually badly contaminated by various noise sources, considerable and accurate signal conditioning and preprocessing was necessary. A description of the steps following from the data recording to produce the diagnosis results is provided View full abstract»

  • Structured prototyping for requirements specification in expert systems and conventional IT projects

    Page(s): 82 - 89

    It is widely held that expert systems are small systems and that the methods used to build them do not scale up to the sort of large commercial systems necessary for their mature acceptance. The author looks at prototyping from the point of view of the traditional system development life cycle and shows how the latter can be modified to incorporate fast prototyping in building large systems which may incorporate expert systems. He also introduces a classification of different approaches to prototyping View full abstract»

    Technology management is a topic of increasing importance as technology itself becomes more significant in the running of economic, educational and business institutions. This results in a competitive situation which demands effectiveness and efficiency for commercial survival. The key to success is good management. People have much greater difficulty solving the human and organisational problems than the technical ones. It seems that society is very effective at solving technical problems but comparatively poor at motivating and organising individuals to employ their technical expertise in the best way for the common good. In attempting to improve this situation, the three most important aspects requiring management attention are: people, goals and change View full abstract»

  • Parallel processing in large-scale simulation: motivation and methods

    Page(s): 74 - 79
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (508 KB)  

    The use of parallel computers is discussed in the context of modern control engineering practices. The author outlines potential advantages, the role of the control engineer, and suggests methodologies, with particular reference to the problem of simulating large-scale systems. Many of the ideas introduced are general enough to extend to a much wider class of problems View full abstract»

  • Transputer analysis of visual texture

    Parallel processing is being increasingly looked to for cost-effective solutions to complex computational problems. Image processing often generates these due to the large amount of data required for images. The transputer provides a relatively cheap and increasingly available, parallel-processing solution. A transputer array is used to solve a specific image processing problem and the steps taken to optimise the performance are described View full abstract»
