Usability Analysis of Visual Programming Environments: a `cognitive dimensions' framework

by T. R. G. Green, M. Petre - JOURNAL OF VISUAL LANGUAGES AND COMPUTING , 1996
"... The cognitive dimensions framework is a broad-brush evaluation technique for interactive devices and for non-interactive notations. It sets out a small vocabulary of terms designed to capture the cognitively-relevant aspects of structure, and shows how they can be traded off against each other. T ..."

. The purpose of this paper is to propose the framework as an evaluation technique for visual programming environments. We apply it to two commercially-available dataflow languages (with further examples from other systems) and conclude that it is effective and insightful; other HCI-based evaluation

The synchronous dataflow programming language LUSTRE

by N. Halbwachs, P. Caspi, P. Raymond, D. Pilaud - Proceedings of the IEEE , 1991
"... This paper describes the language Lustre, which is a dataflow synchronous language, designed for programming reactive systems --- such as automatic control and monitoring systems --- as well as for describing hardware. The dataflow aspect of Lustre makes it very close to usual description tools in t ..."

Statecharts: A Visual Formalism For Complex Systems

by David Harel , 1987
"... We present a broad extension of the conventional formalism of state machines and state diagrams, that is relevant to the specification and design of complex discrete-event systems, such as multi-computer real-time systems, communication protocols and digital control units. Our diagrams, which we cal ..."

call statecharts, extend conventional state-transition diagrams with essentially three olements, dealing, respectively, with the notions of hierarchy, concurrency and communication. These transform the language of state diagrams into a highly structured' and economical description language

Dataflow Process Networks

by Edward A. Lee, Thomas Parks - Proceedings of the IEEE , 1995
"... We review a model of computation used in industrial practice in signal processing software environments and experimentally in other contexts. We give this model the name "dataflow process networks," and study its formal properties as well as its utility as a basis for programming language ..."

Control-Flow Analysis of Higher-Order Languages

by Olin Shivers , 1991
"... representing the official policies, either expressed or implied, of ONR or the U.S. Government. Keywords: data-flow analysis, Scheme, LISP, ML, CPS, type recovery, higher-order functions, functional programming, optimising compilers, denotational semantics, nonstandard Programs written in powerful, ..."
Abstract - Cited by 365 (10 self) - Add to MetaCart
optimisations that depend upon data-flow analysis: common-subexpression elimination, loop-invariant detection, induction-variable elimination, and many, many more. Compilers for higherorder languages do not provide these optimisations. Without them, Scheme, LISP and ML compilers are doomed to produce code

Specification and analysis of system architecture using Rapide

by David C. Luckham, John J. Kenney, Larry M. Augustin, James Vera, Doug Bryan, Walter Mann - IEEE Transactions on Software Engineering , 1995
"... Rapide is an event-based concurrent, object-oriented language specifically designed for prototyping system architectures. Two principle design goals are (1) to provide constructs for defining executable prototypes of architectures, and (2) to adopt an execution model in which the concurrency, sync ..."

Dataflow Analysis of Array and Scalar References

by Paul Feautrier - International Journal of Parallel Programming , 1991
"... Given a program written in a simple imperative language (assignment statements, for loops, affine indices and loop limits), this paper presents an algorithm for analyzing the patterns along which values flow as the execution proceeds. For each array or scalar reference, the result is the name an ..."

LUSTRE: A declarative language for programming synchronous systems

by P. Caspi, D. Pilaud, N. Halbwachs, J. A. Plaice - In 14th Symposium on Principles of Programming Languages (POPL’87). ACM , 1987
"... LUSTRE is a synchronous data-flow language for programming syetema which interact. with their environments in real-time. After an informal presentation of the language, we describe its semantics by means of structural inference rules. Moreover, we ehow how to use this semantics in order to generate ..."

Relations in Concurrency

by Glynn Winskel
"... The theme of this paper is profunctors, and their centrality and ubiquity in understanding concurrent computation. Profunctors (a.k.a. distributors, or bimodules) are a generalisation of relations to categories. Here they are first presented and motivated via spans of event structures, and the seman ..."

, and the semantics of nondeterministic dataflow. Profunctors are shown to play a key role in relating models for concurrency and to support an interpretation as higher-order processes (where input and output may be processes). Two recent directions of research are described. One is concerned with a language
