    An understanding of the processes used for developing new products can help a manager reduce the number of new product failures for his company. The authors describe three of the process patterns used by companies when developing new products and discuss the characteristics of these processes. They also discuss the influence these processes may have upon the people involved in new product development. View full abstract»

    The merits of a sequential approach to the design of multi-variable combinational logic circuits are discussed, and simple algorithms for computer-aided design are described. Illustrations of the method, both for completely specified and for incompletely specified logic functions, are given. View full abstract»

    A comprehensive investigation of the r.f. properties of a range of samples of carbon fibre composite materials has been made. These samples were chosen as being representative of those which have been used or are likely to be used in aircraft construction. This paper is in two parts, first the investigations made to determine the electrical resistance characteristics of small samples of CFC materials in the frequency range from d.c. to 300 MHz, and the second part which describes the investigation of the screening performance of larger samples in the frequency range 0.15¿30 MHz for the magnetic mode and in the range 50¿1000 MHz for the electric mode. The methods of measurement which were developed during the investigation are described in detail together with the experimental results, and the conclusions include some indication of the implications of the installation of CFC panels for e.m.c. problems in aircraft.

    The teletext and videotex systems which are in service in the UK provide a mosaic type of graphics, permitting the display of simple pictures and diagrams. However several uses for an improved graphics facility have been identified which could benefit from still colour television pictures of normal definition and gradation. An experimental system has been developed to investigate the feasibility of such a picture option for future viewdata services. Since the available data rates are rather low for picture transmission, the application of image data compression techniques is imperative for acceptable picture update times at the receiver.
