Aided Design

In the apparel field, there is the problem of creating a design with respect to an underlying standard form. Instead of applying general-purpose three-dimensional computer aided design systems to such tasks it is proposed that design can be carried more efficiently with bespoke design systems. These can be targeted to deal with the problems of accurately defining the offset surfaces which comprise the garment. Such a system is introduced and the methods of data entry are discussed. Position on the three-dimensional form is determined using a digitizer tablet and fit with respect to the form is specified by an offset dimension. It is shown that complex garment pieces with variable fit can be quickly specified within the system.

The complexity of integrated circuits continues to grow, and chips with over 10 8 transistors will be in widespread use by the late 1990s. These chips will combine general purpose processors with subsystems for communications and other specialized tasks. They will be far too complex for the design to be tested, and manufacturing volumes will be far too high for the design to be wrong! Mathematical techniques have already been applied to the design of parts of VLSI chips. Most of this work is experimental, and requires an unusual combination of engineering, mathematical and programming skills. Sometimes new theoretical work is needed, and specialized tools may have to be constructed. Despite these difficulties, mathematical techniques are playing an important role in the design of microprocessors at Inmos, and techniques suitable for incorporation in standard computer-aided design systems are emerging.

. Modeling of several antennas by the method of moments in the TALGAT system was performed for comparison with tested results. At first, the published results for half-wave and wave dipoles are compared with our results. Current module distributions and frequency dependences of the real and imaginary parts of the input impedance are obtained. The results showed a good match. Then the published experimental and analytical results for the radiation pattern and frequency dependence of the admittance of the gull shape antenna are compared with our results. The convergence of the results with segment length decreasing is shown. A good match is obtained. It is shown that detailed testing is important in the process of implementation and development of computer-aided design systems
