title Modeling Polyhedral Solids Bounded by Multi-Curved Parametric Surfaces
source Computer Aided Design May, 1983. Vol. 15: pp. 141-146 : ill. includes bibliography.
summary An integrated solids modelling system for representing and manipulating objects bounded by bicubic parametric surfaces is presented. Its basic capabilities include the representation of solids through a surface based model, such that the surface underlying any face can be replaced by another surface that has been modelled independently. Other functionalities include scaling, rotation and translation of shapes and their pairwise combination into more complex shapes by means of spatial set operators. This approach integrates within a single system the representation and manipulation of polyhedral solids bounded by multi-curved parametric surfaces, thereby combining solid modelling with surface modelling techniques
keywords solid modeling, curves, curved surfaces, integration, systems, B-rep, intersection, boolean operations

title Interactivity and Graphics as a Support for the Design of Cable Nets and Trusses
source Proceedings of the International Conference eCAADe [European Computer Aided Architectural Design Education] Brussels (Belgium) 1983, pp. IV.26-IV.41
summary This paper deals with an important aspect concerning the quality of a computer aided design (CAD) program, namely the human-computer interface. To fix the ideas,the user interface of FORCE, a program for the design and visualisation of cable nets and trusses, is considered The new design of this user interface was necessary to support an easy extension of the dialogue, both alpha-numerical and graphical. The new approach includes a separation of the interaction procedures and the application modules.

title Building Knowledge-Based Systems : The PSN Experience
source IEEE Computer. IEEE Computer Society, October, 1983. vol. 16: pp. 83-88. includes bibliography
summary Knowledge-representation languages have been classified traditionally as declarative or procedural, depending on whether their basic features come from mathematical logic or data structures on one hand, or from programming languages on the other hand. Procedural representation languages are particularly well suited for heuristic knowledge, and their use can lead to efficient searching on the part of an expert system. Many attempts have been made to integrate features of declarative and procedural representation languages. PSN is one attempt that focuses on the integration of semantic network and procedural notions

title The Evaluation of Text Editors : Methodology and Empirical Results
source Communications of the ACM. April 1983. vol. 26: pp. 265-283 : diagrams and tables. includes bibliography
summary This paper presents a methodology for evaluating text editors on several dimensions: the time it takes experts to perform basic editing tasks, the time experts spend making and correcting errors, the rate at which novices learn to perform basic editing tasks, and the functionality of editors over more complex tasks. Time, errors, and learning are measured experimentally; functionality is measured analytically; time is also calculated analytically. The methodology has thus far been used to evaluate nine diverse text editors, producing an initial database of performance results. The database is used to tell us not only about the editors but also about the users - the magnitude of individual differences and the factors affecting novice learning

title Job and Health Implications of VDT Use : Initial Results of the Wisconsin-NIOSH Study
source Communications of the ACM April, 1983. vol. 26: pp.284-294 : tables. includes bibliography.
summary Magnitudes and correlates of stress were investigated among 248 office workplace VDT users and 85 nonuser counterpart using field survey and objective physical measurement technique. Other than a tenuous indication of increased eyestrain and reduced psychological disturbances among users, the two groups were largely undifferentiated on job- attitudinal, affective, and somatic manifestations of stress. However, aspects of working conditions were judged less favorable by VDT users. Stress mechanisms were much the same for both groups, involving psychosocial as well as physical environmental job attributes
keywords For VDT users, the chair and workstation configuration were particularly important predictors of musculo-skeletal disturbances, as were corrective eyewear use and ambient lighting for visuo-ocular

title A Dynamic Space-Time Network Flow Model for City Traffic Congestion
source 43 p. : ill. graphs Pittsburgh, PA: Design Research Center CMU, December, 1983. DRC-70-18-83. includes bibliography
summary A space-time network is used to model traffic flows over time for a capacitated road transportation system having one-way and two-way streets. Also traffic signal lights, which change the network structure, are explicitly incorporated into the model. A linear (time) cost per unit flow is associated with each arc, and it is shown that under the model structure, travel time on a street is piecewise linear convex function of the number of units travelling on that street. Hence congestion effects are explicitly considered while maintaining the linear nature of the model. Two efficient solutions methods are proposed. A network flow solution for multiple source single destination network and a shortest path solution for a single source single destination network
