An extended feedback structure of intelligent computer-aided control systems design based on object-oriented language

Annual Review in Automatic Programming 1989年第PART 2期15卷 59-64页

作者： Ono, O Department of Electrical Engineering School of Science and Technology Meiji University Tama-ku Kawasaki Kanagawa 1-1-1 Higashimita Japan

In this paper we consider about the structure of an intelligent computer-aided control systems design (CACSD) based on object-oriented language. We also indicate a frame in which the controlled system is a receiver and the control design is a message. From this view we construct the extended feedback structure of a design process. The graphics produced by object-oriented language is important for designing control systems, because it is concerning with the characteristics of a control system but also presenting the structure of a control. We point out that the graphics or the symbols are treated as input and output patterns produced from the design process. It is displayed as a complex potential which is an extended form of the Bode diagram. The complex function expresses a control structure as the transformation of a transfer function. Finally We explain a graphic data-base for intelligent control systems design and a human fuzziness which is transferred into the computer through graphics or symbols. © 1990.

Points-to information is essential in software engineering, including compiler optimization, instruction-level parallelism, program verification, and so on. The propagating of points-to information along paths of a program can be viewed as the "frame problem" in a dynamic world. As a primary knowledge representing and reasoning tool in Artificial Intelligence, Answer Set Programming (ASP) provides a natural and concise way to express the frame problem. We present a collection of ASP rules to model the propagating of points-to information along paths of an object-oriented program. With these rules and basic facts of a program. points-to information at each program point can be computed easily. This makes it possible to acquire useful information for program analysis through existing ASP solvers.

A graphics user interface called GLAD (Graphics language for Database) has been proposed as a unified interface method for interaction with a database. The GLAD interface is a graphic object-orient environment which provides a rich intuitive interaction for the user. The interface between GLAD and the user is accomplished through the use of an object-oriented language(OOL). Predefined classes in an OOL provide a robust capacity for quick prototype implementation. The thrust of this thesis is to describe the current status of the GLAD implementation and show how the use of an object-oriented language is an effective tool for implementation of the GLAD interface.

ACTOR, an object-oriented follow-on language to Smalltalk, is used in an implementation of a prototype video store management package and in the implementation of a tree abstract data type package. The language has high power, familiar syntax, portability, windowing and extensive development tools which make it an excellent choice for prototyping. The intuitive nature of the language and the close connection between modeling physical and logical entities are aptly demonstrated by detailed discussion of the design of the video management package. Implementation of binary search tree and AVL tree abstract data types demonstrate that coding of constructs which are procedural in nature does not exploit the strengths of an object-oriented language such as ACTOR.

学位级别：硕士

In this thesis we discuss the design issues of a styl- ized natural language syntax for Omega, an object-oriented programming language tuilt upon rule-based pattern matching. Emphasis is placed en simplicity and flexibility in the design. The feasibility of the proposed grammar (Omega-1.5) is evaluated by developing a prototype translator to trans- late the Omega-1.5 grammar into the predicate logic style of Cmega-1. Sample applications are provided to examine the features of the grammar and to explore possible application areas. limitations in the design are analyzed and potential ameliorations are suggested. We conclude with a general assessment of the overall Omega system.

Grace is a new object-oriented language that supports a variety of approaches to teaching programming. It integrates accepted new ideas in programming languages into a simple language that allows students and teachers to focus on the essential complexities of programming rather than the accidental complexities of the language. We motivate Grace, review its design, and evaluate it against Kolling's criteria.

In this paper, we suggest a new object-oriented functional language, OOId, which is based on a functional language fd and extended with object-oriented language features. We also discuss how to map OOId program onto DAVRID, which is a kind of multithreaded architecture based on the dataflow model. The comparison of execution time of two programs written in fd and OOId for the matrix multiplication problem, shows we can effectively run OOId program with just a little slow-down of execution time. In addition, the rate of stow-down is decreased, as the size of the matrix is larger. That means we can use good features od object-oriented language by paying just a little slow-down of execution time.

An object-oriented concurrent language for extensibility and reuse of synchronization components

引用

COMPUTERS AND ARTIFICIAL INTELLIGENCE 1996年第5期15卷 437-457页

作者： Thomas, L THOMSON CSF CENT RECH LAB F-91404 ORSAY FRANCE

Concurrency in object oriented languages seems natural. However well known problems arise when we try to define such concurrent object oriented languages. These problems deal with the interferences between expressing true concurrency inside objects and expressing re-use. This article presents a concurrent object model and illustrates through various examples how it solves these interferences.
