  • Calculation of poissonian fields by means of the method of tubes and slices

    Publication Year: 1985, Page(s):149 - 156

    Dual variational principles have been devised to provide a simple and accurate method for the calculation of the energy of Poissonian fields. The method is illustrated by the calculation of the inductance of a T-shaped conductor in a slot with iron boundaries. In comparison with the normal finite-element method, the computing time is reduced by at least an order of magnitude. View full abstract»

  • Complementary variational formulation for eddy-current problems using the field variables E and H directly

    Publication Year: 1985, Page(s):157 - 164
    Cited by:  Papers (13)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1067 KB)

    Complementary functionals, expressed in terms of either E and ¿¿ ¿¿ E or H and ¿¿ ¿¿ H, applying to linear eddy-current problems are given and are shown to be stationary subject to simple, and sometimes natural, boundary constraints. The analysis is carried through to a late stage before the pre-Maxwell zero-displacement current approximation is applied, in order not to obscure the principal resul... View full abstract»

  • The use of transformations in applying boundary conditions to three-dimensional vector field problems

    Publication Year: 1985, Page(s):165 - 170
    Cited by:  Papers (5)

    A method for calculating three-dimensional eddy-current distributions has previously been described. It consists of using magnetic scalars to model fields in regions in which eddy currents do not flow, coupled to a three-component vector, the magnetic vector potential A, which describes the field inside eddy-current-carrying conductors. Applying boundary conditions to the region containing A is st... View full abstract»

  • Surface impedance of saturating iron in travelling fields

    Publication Year: 1985, Page(s):171 - 177
    Cited by:  Papers (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1098 KB)

    The step-function approximation to the B-H curve for saturating iron is used here to examine the behaviour of the surface impedance in the presence of travelling surface fields. The method is an extension of that employed by other authors for pulsating fields and uses the concept of a wavefront which sweeps into the medium twice every cycle. The magnitude and phase of the surface impedance is comp... View full abstract»

  • Nickel and chromium plated terminals in current transformer circuits

    Publication Year: 1985, Page(s):178 - 180
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (327 KB)

    When nickel or chromium plated terminals are used in the circuits of precision current transformers, instabilities are often observed in their calibration. The nature of these instabilities suggests the cause to be small DC components flowing in the transformer windings. In the paper, the DC components are explained in terms of semiconducting oxides on the terminal contact faces. Experimental resu... View full abstract»

    To maintain a high standard of living, Britain has to be a large manufacturing base supplying most of its needs for most types of goods, as well as for export. This will not happen unless we put more resources into educating and training engineers, with the specific intent of expanding the manufacturing industries. This needs changes in the engineering colleges and in their relationships with indu... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1218 KB)

    The Council for National Academic Awards has been in existence for 21 years. The paper reviews the origins and development of the CNAA and describes its present structure and role in higher education generally. In particular, the position which the CNAA holds in the education of electrical and electronic engineers to degree level is outlined. View full abstract»

  • When the engineering has to stop

    Publication Year: 1985, Page(s):193 - 198
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (962 KB)

    The paper proposes that, in the UK, there needs to be a fundamental change in the attitudes of engineers. Engineering alone is not enough for engineers. They need to see themselves in the broader context of society as a whole. At present there is a general distrust by the general public of science and engineering, mainly because engineers have kept quiet for too long, and have been letting facts s... View full abstract»

  • Systematic methods for the problem solving process with particular reference to design

    Publication Year: 1985, Page(s):199 - 212
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1753 KB)

    A model is constructed to describe the relationship of the various stages of human activity within the process of solving a system problem. A compendium of techniques are described in the paper, relevant to different stages of the process. These cover methods for illustrating problem structure, obtaining a decision sequence to govern the design process, and the choice of a course of action. Explic... View full abstract»

  • The economics of innovation

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1480 KB)

    There are many different kinds of technical innovations, but one of the most important distinctions is between incremental improvements to an existing range of products and processes and the revolutionary transformations brought about by entirely new technologies and production systems. Such deep-going transformations justify the expression `change of paradigm¿¿ because they affect almost all bran... View full abstract»

    Eight papers at the Colloquium reported in this paper include a review by the Director General of BSI of how the quality system and design standards for industry (BS 5750) have been developed from the basis of the defence standards, and are shortly to be adopted as worldwide ISO standards. Other speakers enlarged on this, describing the new approach to unified procurement and project support, and ... View full abstract»

  • William Henley, pioneer electrical instrument maker and cable manufacturer, 1813 to 1882

    Publication Year: 1985, Page(s):249 - 261
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (2209 KB)

    William Henley provides a case history of a pioneer manufacturer of electrical instruments and equipment, who expanded from instrument making into the production and laying of submarine cables. At one time he employed 2000 men and owned three cable laying ships. By 1874 he had expanded his firm beyond what one man could manage, and, when the recession came, he failed. He had lived frugally, but in... View full abstract»
