Abstract: There are two Computer courses currently given at the Graduate School of Design. One is a theory course and the second is a workshop. The workshop is primarily a “hands-on” graphic programming course using Harvard's PDP-10 computer and a variety of Tektronix CRT's and two 4051 micro-processors. The course teaches the fundamentals of computer, graphic programming (BASIC and FORTRAN), as well as computer graphic technology and how this technology is applied to architectural design. There is one two-hour lecture per week in which application areas are dealt with by explaining graphic data structures and the mathematics and algorithms that are used to support the particular application. There are also weekly meetings with tutors to work on individual problems.The other course is an introduction to systems and design methods using the computer to illustrate various algorithmic aspects of the design process. The course looks at design from a systems point of view and includes a basic introduction to systems, models, simulation and quantitative analysis applied to physical design. Comprehensive approaches to design and planning are described and illustrated using existing computer aided design models. There is a great deal of utilization of existing interactive graphic design programs to illustrate aspects of construction management, planning, architectural programming, space allocation, two and three dimensional graphics with hidden line solution and shading of surfaces.

Abstract: A design methodology for DBMS is presented. The methodology consists of three interacting models: a model for the system structure, a hierarchical performance evaluation model, and a model for design structure documentation, which are developed concurrently through a top-down design process. Thus, using this methodology, the design is evaluated and its consistency checked during each phase of the design process. It is shown that systems designed using this methodology are reasonably independent of their environments, reliable, and can be easily modified. A modest example is used to illustrate the methodology.

Abstract: It is evident that the use of impact simulation, static, and dynamic analyses in the pre-prototype phase of the design process can significantly improve the structural efficiency of the design process can significantly improve the structural efficiency of the automobile. As a result of this design project, the accuracy of the structural modeling and analysis was verified by experimental data obtained from a fabricated test vehicle, and the potential value of design through analysis was demonstrated by a significant reduction in structural weight of the project vehicle. /SAE/

Abstract: In this report a language (SDL) for describing structural properties of digital systems will be presented. SDL can be used at all levels of the design process, i.e. from the system level down to the circuit level. The language is intended as a complement to existing computer hardware description languages, which emphasize behavioral description. The language was motivated partly by the nature of the design process.

Abstract: : This handbook consists of in-depth treatments of several specific classes of design problems, employing and advancing the theoretical development and initial structural applications of AMCP 706-192. The approach taken is to treat problems that fall in fields such as fail safe structural design, structural dynamics optimization, contact analysis and design, and vehicle suspension design in enough depth that advanced system designers can follow through a relatively realistic design problem. It is hoped that this set of examples also will motivate accelerated application of techniques for mechanical design optimization. Each chapter is self contained, as regards this handbook, but most chapters rely on algorithms and basic results contained in AMCP 706- 192.

Abstract: To an engineer, a "solution" usually means a set of curves or charts, while the computational technique used to obtain them is probably not important. Hence, the pedagogic objective of inculcating in a student of engineering design the "physical appreciation" of a problem can be effectively achieved through the use of "canned" design software packages.

Abstract: The specifications of a data-structure are essentially linked to the representative model, to the functional links to be obtained amongst the various data and the action to be taken on such structure 1,2 . An engineering drawing is the two-dimensional representation obtaibed according to precise accepted standards of three-dimensional objects. The data-structure, therefore, which represents an engineering drawing must contain all the connections among the two-dimensional graphic elements of which the drawing is composed. It should also contain a complete description of the three-dimensional object represented to allow action on the drawing at any level through its two-dimensional representation. On the other hand, an analysis of the various phases of the design process which lead to the production of final working drawings will show that the three-dimensional model of the mechanical part becomes increasingly detailed and complex, as are the drawings used to illustrate it. The quantity of drawings which accompany the various phases of the design process increases and the types of action to be taken on such drawings refer to an ever greater extent to details which do not substantially alter the piece from a functional point of view, but which complicate its shape to an appreciable degree. Furthermore, at such a level, the drawing contains a large amount of data of a technological and constructive nature which are also continually changed or amended. The use of computer-aided drafting systems is justified where large numbers of considerably complex drawings are involved. During the final stage of mechanical design where changes essentially concern details (from the point of view of the shape of the piece); it would be unreasonable at this level to use for the storage of the drawing, a data-structure which contains a complete and faithful representation of the illustrated mechanical part with its great complexity 3 . It will therefore be sufficient for the data-structure for handling the drawings to contain only those functional links which are of interest at the detailed design stage.

Abstract: IN ORDER TO REDUCE THE CORROSION OF A JOINT COMPRISING SEVERAL METALS IT IS NECESSARY TO UNDERSTAND THE BASIC PROCESSES OF SOME TYPES OF CORROSION AND TO RECOGNIZE THE FACTORS INFLUENCING THE RATE OF CORROSION. ONCE THIS HAS BEEN UNDERSTOOD, THE DATA ARE APPLIED TO ALL PHASES OF ENGINEERING DESIGN, ESPECIALLY CAR DESIGN, E.G., THE SELECTION OF MATERIALS, PREVENTIVE MEASURES AND PHYSICAL DESIGN. THE FINAL STAGE MUST BE THE DETERMINATION OF THE POSSIBILITY OF APPLYING THE DESIGN OF MECHANICAL COMPONENTS. THE DISCUSSION DEALS WITH EACH OF THE SPECIFIC FIELDS WHICH FORM THE OVERALL DESIGN. THIS IS A TRANSLATION OF SAE PREPRINT 770292.

Abstract: The theory of formal languages is applied to the systematic top-down design of file processing programs. A methodology is described which leads to well structured programs for a large class of data processing problems. The method leads to more reliable programs because it is easier to check the method steps than an intuitive program. The method and its limitations are illustrated by the design process for some data processing programs. The limitations of the method are explained as the result of a theorem about formal languages.

Abstract: The design of a distributed data base is a complex and difficult task requiring careful consideration of data organization, data distribution, user interface, updating/retrieval schemes, program/data placement, security policies and reliability issues. In this paper, we have discussed a design methodology which can be used to design a distributed data base. This design methodology is a systematic way to guide the designer in making decisions during the requirement process phase, the design process phase and the implementation phase. We conclude this paper by examining the architectural issues in the design of distributed data bases.

Abstract: There are many levels of abstraction through which a designer passes when implementing a microprocessor chip set or system. He usually begins by configuring the application for the microprocessor, bus, and peripherals (memory, etc.). Section at a time, he expands the system components into a Register Transfer level diagram, followed by a detailed chip or gate description. This paper will show how a hierarchical simulator aids each phase in the design by modeling elements at all levels from the processor as a black box down to gate expansion. This procedure parallels the design process for verification and allows experimentation at each stage. The SAGE2 (Simulation of Asynchronous Gate Elements - Version 2) system will be used to show the features and benefits of incorporating a hierarchical simulator into the design process. Related simulation tools will be discussed as well as hierarchical modeling considerations. Examples are shown throughout to show microprocessor system debugging features.

Abstract: In the past few decades man has become increasingly aware of the effects of the built-environment upon human experience and behavior. Population growth, industrialization and urbanization have been staggering since World War 11. In the United States these have resulted in the populace increasingly movihg from a primarily rural and agrarian society to a highly technical and specialized one with people living and working in densely populated urban areas. This rapid alteration in life style has made modifications in living and working environments necessary, yet mtJ1 recently, interiors were not designed on the basis of any clear or consistent set of expectations. Interior designers operated on a pre-empirical intuitive level, combining design elements into a coherent pattern without attempt. ing to evaluate the effects of the interior environment on its users. As a result, some designs were more effective, while others were not, depending solely on the ability of the interior designer to "psyche out" the client and project patterns of use. There are still many buildings and interiors which are being conceived, commissioned, executed and even reviewed by members of the design profession and their clients, without any input from the end users.

Abstract: The manufacturing-related tasks in the engineering design of digital systems are those processes which translate a logic design into a functioning physical system. That is, they begin with a description of the system as an interconnection of logic units (such as gates, flip-flops, counters, memories, ALU's, etc.) transforming it into a description of the placement of physical modules and the wiring which interconnects specific terminals on these modules. This portion of the design process has been the one which first saw substantial application of computing, vastly improving the speed, accuracy and capacity of the design organization. It is in this area still that the bulk of the production digital design automation systems are categorized.

Abstract: This paper addresses the engineering problem of optimal design from the standpoint of minimizing cost of production subject to acceptable performance in the worst case under as many unknowns and nonideal outcomes that can be reasonably accommodated in the design process in an integrated fashion. Optimal design centering, optimal assignment of component tolerances and optimal tuning (including tuning by both the manufacturer and by the customer) in the face of uncertainties in the model and external factors affecting the performance are considered. It is explained how even for a relatively small number of components a very large number of constraints and variables may have to be considered. Following the introduction a general statement of the requirements of the worst-case approach to the problem is made. A number of observations on important points concerning the size of the problem and its effective solution are made. A brief review of theoretical and computational work carried out by the author and his colleagues is presented.

Abstract: This paper deals principally with engineering design problems in which either a large volume of production is envisaged, e.g., integrated circuits, or in which only a few units are to be custom made, e.g., filters for satellite applications. All designs are considered subject to manufacturing tolerances (e.g., on physical dimensions), material uncertainties, (e.g., on temperature), model uncertainties (e.g., on equivalent circuits) and so on. Attention is directed in this presentation towards the modelling, the design and the manufacture of electrical circuits such as filters, amplifiers and switching circuits. Hence, certain undesirable effects which deteriorate performance may be due to electromagnetic coupling and mismatched terminations, particularly at high frequencies.

Abstract: This paper summarizes the ways in which a transit-station simulation model could be developed to function as a more integral part of the design process. It examines in detail the interface of the user with the model. Specific problems dealing with network and spatial representation are discussed, and the model output is matched with the information needs of the designer at the appropriate stages in the design process. The paper concludes with a discussion of the cost-effectiveness of station-simulation models. /Author/

Abstract: This article will discuss an automated approach to designing digital systems which is based upon the use of System Description Languages (SDL)1,2,3 and Microprogrammable Bit Slice Microprocessors (MBSM)4,5 Both of these concepts have started to reach maturity in recent years with the result that Computer Aided Design (CAD) systems6,7,8 are starting to evolve to a level whereby they may be truly useful in automating certain of the traditionally difficult and time consuming steps in the digital systems design process In addition to simply minimizing the time consumed in the design process, an automated design approach also opens the possibilities of evaluating different hardware system configurations through simulationThis article will discuss an approach taken at the University of Connecticut to realize a limited form of a CAD system which is based upon a high level design language and the Intel 3000 Family Microprogrammable Bit Slice Microcomputer The overall design system is called the Restructurable Microprocessor Design System (RMDS)10 and it has been realized in a two phase form This consists of a high level language system specification phase which occurs in the University Computer Center This step generates a semi-complete design of the hardware system including the system control unit An implementation phase may then occur in the Computer Science Microprocessor Laboratory where the design may be translated into a hardware form
