  • Forty years in control

    Publication Year: 1985, Page(s):1 - 8
    Cited by:  Papers (1)

    The large number of control devices which had been invented over the previous two centuries led, by about 1930, to the conception of a control theory with fundamental principles basic to all forms of control. The last war saw the use of this theory to develop sophisticated mechanisms of high precision. The paper gives the development of the science and engineering of control over the last 40 years...

  • IEE Management & Design Division: Chairman's address. By our work is the city established

    Publication Year: 1985
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (891 KB)

    The paper makes the claim that civilisation is founded on the work of engineers. It takes its title from the book of Ecclesiasticus, which speaking of craftsmen says that `by their work is the city established¿¿. The paper argues further that management and design are the core of engineering. It gives the view that there is an organised framework of concepts and principles underlying both manageme...

  • IEE Science, Education & Technology Division: Chairman's address. All SET for CAE

    Publication Year: 1985, Page(s):15 - 20

    Computer-aided engineering is an all-embracing term to cover the drawing together of all aspects of the design and manufacture of a product. CAE systems can now be purchased which can greatly assist the engineer in his efforts to produce a better, more competitive product in a shorter time. The introduction of CAE causes changes in the structure of a company. Human communication becomes vitally im... View full abstract»

  • Electromagnetic levitation of rotating cylinders

    Publication Year: 1985, Page(s):21 - 27
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (722 KB)

    Stable electromagnetic levitation of spinning conducting cylindrical rotors has been demonstrated theoretically for the first time. General expressions of the quasistationary magnetic vector potential, for a rotating, conducting, cylindrical shell in the proximity of a distribution of parallel straight wires carrying currents, have been obtained by assuming a two-dimensional field. For a practical... View full abstract»

  • Synthesis of electrical fields by optimisation of the shape of region boundaries

    Publication Year: 1985, Page(s):28 - 32
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (474 KB)

    The paper describes a method for the synthesis of the electrostatic field corresponding to the potential of boundaries of an unknown shape. The proposed algorithm makes it possible to determine the optimal boundary structure of the region where it is necessary to obtain a specified electrical field distribution. The main idea is based on the application of one of the regularisation methods for sol... View full abstract»

  • Magnetoresistive transducers for the measurement of magnetic tape speed

    Publication Year: 1985, Page(s):33 - 39
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (939 KB)

    A method of employing space-periodic magnetoresistive transducers for the direct measurement of the speed of magnetic recording tape is described. The method is, in principle, similar to that devised for measuring strip speed in steel mills, using an inductive transducer. The wavelength-selective transducer is connected in a feedback configuration to an inductive write head placed upstream of the ... View full abstract»

  • Marx circuit modified by adding a tail sphere gap to generate lightning impulses lasting a few microseconds

    Publication Year: 1985, Page(s):40 - 44
    Cited by:  Papers (3)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (637 KB)

    A substantial decrease in efficiency compared with the standard lightning impulse occurs in the production of very short-tailed lightning impulses by means of the Marx generator. A modification of one of the typical Marx circuit configurations, i.e. the series connection of a sphere gap and an inductance to the tail resistance, is suggested here to overcome this drawback. Digital simulation of the... View full abstract»

  • Determination of the complex dielectric constant, electric field and conductivity at the boundary of ionised gas

    Publication Year: 1985, Page(s):45 - 49
    Cited by:  Papers (1)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (620 KB)

    A method and boundary probe using an AC bridge as a sensor is described, by means of which the current density J, electric field E, conductivity ¿¿ and complex permittivity of an ionised gas may be determined at a point on its boundary. The probe itself is a three-terminal capacitor transformed into one flat plane, with typical diameters of 1 mm to 3 mm. Fitting flush with the electrode or vessel ... View full abstract»

  • Full-wave computed tomography. Part 3: Coherent shift-and-add imaging

    Publication Year: 1985, Page(s):50 - 58
    Cited by:  Papers (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1139 KB)

    The theory of coherent shift-and-add imaging is summarised, is extended to be more generally applicable than in Parts 1 and 2, and is illustrated with the results of computer simulations and laboratory experiments. 2-dimensional images of collections of cylindrical objects (immersed in a water tank into which plastic containers filled with animal offal can be introduced) are reconstructed by shift...

  • Electrification current and voltage on a cylindrical object in the presence of an ion flow field in an air stream

    Publication Year: 1985, Page(s):59 - 66
    Cited by:  Papers (3)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (842 KB)

    The paper is concerned with the assessment of the electrical environment in the vicinity of HVDC transmission facilities; the ion flow electrification phenomenon has been recognised as the subject of extensive research. The determination of current and electric field at ground level under the facilities and the estimation of electrification quantities on objects placed in an ion flow field is the ...

    This paper uses several familiar expectations to create a larger scenario for postindustrial society. The transition is regarded as a major sociological event, of Renaissance proportions, in which the complexities of our circumstances will elevate the importance of multidisciplined teams. It is suggested that Britain, whose success with technologically innovative teams was brief, but memorable, be... View full abstract»
