1 A User Interface Model and Tools for Geometric DesignPoor user interfaces discourage potential users from effectively utilizing the design capabilities of geometric modeling systems. Because of the complex nature of the underlying representations in such systems, a well structured user interface model, as well as useful and intuitive design tools, are...user interface; computer systems; computer-aided design

The following topics are discussed: On-line operation; Graphics system services; Information displays Inc. display codes; Tektro...1967-11-15
4 A FORTRAN V Interactive Graphical SystemThe system described provides the capability of transforming an ordinary FORTRAN 5 program into a highly interactive program. The converted program makes the user, the display scope, and teletype console all an integral part of the execution of the program. At present, the system allows the user to ...1968-04-03
5 FLEX - A Flexible Extendable LanguageThe FLEX system consists of merged 'hardware' and 'software' that is optimized towards handling algorithmic operations in an interactive, man-machine dialog. The basic form is that of a hardware implementation of a parametric compiler embedded in an environment that is well-suited for semantically d...1968-06
6 Three-Dimensional Input for Computer GraphicsThe paper states the need for three-dimensional input for architectural work using computer graphics. The paper consists of two sections.

7 UNIDEC AssemblerThe report discusses the UNIDEC assembler which runs on the UNIVAC 1108 and passes assembled PDP-8 code over the electronic link between the two machines.1968-06-06
8 Syntax Directed on-Line Recognition of Cursive WritingA syntax organization for recognition of handwritten connected-word is studied in the work. Each writing is cut into strokes at the middle point of every down cave of the writing, and the strokes are named using their directional characteristics and relative size among the strokes. A syntax is organ...1968-07
9 A Computer Program to Plot an Isometric Projection of a Solution Space SurfaceSubroutine ISOPLT was developed for the computer produced CALCOMP display of a solution space surface. The solution space, for the sample plots given in Appendix B, is that of various flow functions of a time dependent, viscous, incompressible fluid flow for various boundary configurations. Also sho...1968-08
10 Space-Form. Computer-Aided Design for ArchitectureThe design approach proposed in the report is generated from basic space-forms. These three-dimensional forms are used by the designer as building blocks to design at every scale--from the most minute details of a given building to the eventual placement of the building in the context of its surroun...1968-09-01
11 An Interactive Continuous Simulation LanguageComputer simulation has come into increasingly widespread use to study the behavior of systems of which the state of the system changes over time. There have been two main types of simulation languages developed to study these systems, continuous simulation languages to study continuous change model...1968-10
12 A Method for Extending FORTRAN V for the Interactive Graphical Solution of Numerical ProblemsInteractive computer graphics offers much in the way of bringing the program user closer to the problem solving algorithm. Techniques may be employed which provide for the execution of the program to be monitored and action taken to help the program find the solution, or to find it more quickly. Log...1968-12
13 Considerations for the Development of a Computer-Aided Electrical Design SystemThe specifications of a computer-aided design system are proposed based on the implementation of a prototype subsystem using UNIVAC 1108 and PDP-8 computers. The design system would aid a designer who wished to select and specify electrical fixtures, controls and circuits, and place them in a buildi...1969-09
14 A Dynamic Model for Computer-Aided ChoreographyThe application of the digital computer in the field of dance choreography is a relatively unexplored area. The use of the computer in other arts is more widely known. The report describes an interactive, FORTRAN 5 UNIVAC 1108 computer which relates the angular movements of the joints of the display...1970-06
15 An Analytical Approach to Computer Systems SchedulingThe report examines some aspects of the problem of allocating resources in a multi-programmed computer system. It first investigates to what extent the users might participate in resource allocation decisions; a system that dynamically determines the prices of services is advocated. A model is studi...1970-06
16 Design for a micromodular self-timed system, AAbstract: Self-timed systems lend themselves readily to interactive design and implementation of concurrency. These systems and their properties are discussed, and the implementation for a micromodular system is described. The use of formal techniques to design asynchronous machines with concurrency...Switching systems; micromodular representations; self-timed systems; interactive design; concurrency1972-03
17 Computer graphics approach for understanding prosthetic heart valve characteristicsAbstract: Fluid dynamics principles and numerical analysis techniques are applied in a study of stress distribution in blood caused by the motion of the occluder within the cage of a prosthetic heart valve model. An interactive computer graphics program is developed for the simulation of the flow pr...Prosthetic heart valve; Disc occluder; hemolysis; thrombosis1972-06
