    Initially, the review takes a brief look at the various types of antenna systems that are used on satellites and shows that in terms of the measurement of their radiation characteristics, they can be categorised into two groups, i.e. low-gain (omnidirectional and quasi-omnidirectional) antennas, and medium- and high-gain antennas. With the first group, the main measurement difficulty lies with the... View full abstract»

  • New method for the display of three-dimensional vector fields

    Publication Year: 1980, Page(s):435 - 442
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (775 KB)

    The paper starts by reviewing the limitations of the existing methods of display of vector fields with particular reference to electromagnetic fields. A new method of display is then proposed which uses an arrow of fixed proportions to display the magnitude and direction of the vector field at each point at which it is known. The arrow head has thickness and the whole arrow is scaled in proportion... View full abstract»

  • Novel electro-optical instrument for hole-diameter measurement

    Publication Year: 1980, Page(s):443 - 446
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (539 KB)

    A new instrument has been built for the measurement of hole diameter. It exploits a novel technique in which the diameter of a light beam oscillates, and it has shown a high performance for its cost. It lends itself to automated use. View full abstract»

  • High-pressure sheath to glow transition in a plasma-filled gap

    Publication Year: 1980, Page(s):447 - 451
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (669 KB)

    Results are presented which support the predictions of a simple theory of sheath breakdown. The usual sheath equations are modified to allow for field-induced ionisation and secondary emission. The theory predicts that with increasing voltage the sheath expands to a certain point and then collapses catastrophically to a thickness determined by the external load. Measurements of the impedance of a ... View full abstract»

  • Joule heating in emitting sites on various nonrefractory arc cathodes

    Publication Year: 1980, Page(s):452 - 457
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (827 KB)

    The most common and maximum radii of craters on cathodes of copper, mild steel, silver, silver cadmium oxide and aluminium having various oxide film thicknesses, are reported following 4.5 A arcing of duration between 3.8 ns and 3.5 ¿¿s. The increase in crater radius with arc duration is examined in the light of a simple joule-heating model in a hemispherical region from which material is lost to ... View full abstract»

  • Assessment of undergraduate electrical engineering laboratory studies

    Publication Year: 1980, Page(s):460 - 474
    Cited by:  Papers (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (2292 KB)

    A description of several forms of laboratory study is given, and the major educational objectives likely to be attained via each mode analysed. Current practice of laboratory work in British undergraduate electrical engineering courses is then reviewed. The published methods of assessment of these study modes are considered, and the problems of value judgments of human qualities as well as intelle... View full abstract»

  • New methods in engineering education

    Publication Year: 1980, Page(s):475 - 479
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (690 KB)

    Aalborg University Centre (AUC) started in 1974 in Aalborg, North Jutland, as an experiment in engineering education. The history and the ideas behind the experiment are described in Section 1 of the paper. The key words in the educational method are problem (project)-orientation, teamwork and technology versus society and nature. The study is divided into two parts. The first year, the `base year...

  • Impact of minicomputers on electrical wholesale distribution

    Publication Year: 1980, Page(s):480 - 487
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1247 KB)

    The presence of minicomputers in electrical wholesale distribution inevitably affects the psychology of wholesaling and the attitude of management. In this paper, the problems of the Balmford Group are discussed, and the reason why we invested in a computer system. A brief review for the layman is given of the three types of computer available, and a description of the system eventually adopted, t... View full abstract»

  • Profit, cash flow, employment and the development of new products

    Publication Year: 1980, Page(s):488 - 494
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (765 KB)

    The profits being earned by companies in the electrical sector in the United Kingdom today are insufficient to generate the new capital without which they cannot be competitive in international markets. This restricts growth and leads to falling employment, but choice of suitable development projects can minimise these effects. View full abstract»

  • Industrial innovation

    Publication Year: 1980, Page(s):495 - 497
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (395 KB)

    The mechanism of industrial innovation can be described as a chain with feedback loops to bring out the iterative aspect which is essential to it. The level of the research and development effort in different industrial sectors is subject to prospects for further technological development. The low number of new high-technology companies founded in the 1970s in Europe and even in the USA is a matte... View full abstract»

  • Can engineers develop themselves as managers?

    Publication Year: 1980, Page(s):498 - 504
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1048 KB)

    The concepts of management and training, both individually and in conjunction, are explored; in the process, some popular misconceptions about both are examined. Various national cultural approaches to managing people are discussed. The mystical concept of training is criticised, and some practical approaches to developing managerial skills are suggested. The paper concludes with two genuine case ... View full abstract»
