papers based on his work developing a circulation analysis program to arrange facilities. He discussed how the program logic was arranged and how it works and how it could be applied IO a school layout problem and a hospital layout problem. Dr. Moore also described the basic ideas contained in an improvement type layout program CRAFT (Computerised Relative Allocation of Facilities Technique). Mr. M. Krejcirik (Research Institute for Building and Architecture, Prague) described a construction type program (Rugr Algorithm) which includcsacapability toorientate departments in a particular direction as well as restricting certain departments to the perimeter of the layout. (This paper will be published in the next issue of Cornprr/er.
The Computer-aided Plans Layout seminar, organised jointly by the Post-Graduate Education Centre of the Engineering Societics in Finland and the Department of Mechanical Engineering of the Technical University of Helsinki, held at Dipoli. Otaniemi, Helsinki, during March 1969 was attended by 35 delegates from Scandinavia and Germany. The two day seminar was held to introduce Computer-aided Plant Layout to engineers in Scandinavia and in this respect was very successful. The programme for the two days was very full and started with a paper given by Mr. R. Muthers of Richard Muthers & Associates on ‘Fundamentals of Systematic Layout Planning’. This described the work done by Mr. Muthers on Plant Layout and covered the organisation of data for layout planning, the Relationship Chart and its purpose and application, the space relationship and also evaluated alternative proposals. Mr. Muthers continued with Systematic Layout Planning applied to a specific problem taken from his consulting esperience. Dr. J. M. Moore, a visiting Fulbright Lecturer described his work in developing a Computerised Relationship Layout Planning Program (CORELAP). This program was used later in the seminar as a tutorial program to solve Mr. Muthers’ layout problem. Mr. B. Whitehead (Senior Lecturer, University of Liverpool) present4 two
The problem solving session held at the end of the first day enabled the delegates to actually use both CORELAP and Mr. Whitehead’s Circulation Analysis program on a computer, the data being processed overnight and returned first thing the next morning as tinished layouts. Participants were also given the opportunity to purchase IBM card decks of the CORELAP program and punched paper tapes of a modified version of Mr. Whitehead’s program. This seminar served as an introduction to c-a.d. techniques to Scandinavian engineers and it is to be hoped that it will l-e followed by others in the not too distant future.
The Conference on Computer-Aided Design organised by the Institution of Electrical Engineers and held at Southampton University during April this year attracted a truly international list of participants. The papers given, around 80 in number. were arranged into three parallel sessions and were supposedly grouped by subject. However this grouping was a bit haphazard and several papers on the same subject were grouped so as to conflict. A good example of this was a paper ‘On-line computer-aided control system design using a graphical display’ presented by B. A. Dixon and J. E. Ironside (University of Manchester) which was classified under ‘On-line Systems’ and a Paper given by P. Atkinson and R. L. Davey (Reading University) titled ‘Computer-aided design of closed-loop control systems’. Both these papers covered the same subject and both used interactive graphics terminals.
described in the computer-aided circuit design field and this was probably because the electronics side of c-a.d. had their own conference devoted solely to c-a.c.d. techniques only II months before at Sheffield University. However on the mechanical side several interesting subjects were presented. S. Singh (N.E.L.) described w.ork on computer-aided bearing design. His paper presented a conversational mode program written to design a hydrodynamic pressurefed journal bearing for steady loading. With this program the designer is able to interrogate more data, and modify the design so as to obtain an optimum performance bearing. A paper describing a program to optimise the vertical profile of a road was presented by G. Mitra (Scientific Control Systems Ltd.) and V. Calogero (Institute of Computer Science).

a large list of constraints including the costs of cutting and filling, land purchases, relocation of other roads in the area and vehicle operating costs. The program has already been used in the design of the Sutton-Coldfield By-pass. (A paper by V. Calogero describing part of this program was published in Cwt?pttit~ Aided Desigtt Vol. I, No. 2.) Of special interest, since it uses an analogue computer, is a paper on the calculation of the dynamic characteristics of electromagnetic relays by D. Karo and P. Dhar (University of Aston in Birmingham and English Electric Co.). The study of the dynamic performance of a relay is essential to obtain estimates of velocity, acceleration and kinetic energy which are needed to study contact bounce.
