7 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
8 A framework for hardware design analysis and synthesis using VHDLAn approach for behavioral analysis and synthesis in a single framework is presented. The main advantage of specifying circuits at an abstract level is that they become amenable to formal analysis. A formalism HOP, which is an extended automaton model to describe behaviors of circuits is introduced....VHDL; computer hardware description language1993-03
9 A framework for multi-sensor integration and data acquisitionThis thesis investigates and implements a framework for multi-sensor integration and data acquisition operating in the context of a robot workstation equipped with both contact and noncontact sensors. An appropriate low-level representation of raw data supplied by various sensors is developed. We pr...computers; Spatial proximity graph; 3-D data; object recognition1983-08
10 A front end user interface to a geometric modelling systemThis thesis examines methods for designing effective user interfaces. A particular type of computer system, an interactive geometric modelling system, is investigated with respect to the interface.1987-12
11 A general model for the user interface of screen editorsText editing programs are becoming larger in size and more important in modern operating systems. We present a model for the user interface portions of editors. The model provides a consistent and easy-to-implement environment in which many powerful and useful features can be incorporated. This mode...text editing; text editing program; screen editor; computers1983-03

Emphasis is on the need for tools to assist in the development of nontrivial graphical programs.graphical programming language; data-driven style; computation; computers1983-03
13 A Java-based active network operating system (JANOS)The JANOS prqjects' primary objective was to develop a principle local operating system for active network nodes. The operating system is oriented toward executing untrusted Java bytecode, primarily for management and control.,The original document contains color images.2003-11
14 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
15 A Multiprocessor Implementation of CSP (Communicating Sequential Processes)Communicating Sequential Processes (CSP) is a well known paradigm for communication and synchronization of a parallel computation. A CSP program consists of a collection of processes P(1), P(2),....., P(N) that interact by exchanging message. These message passing primitives, called input and output...1988-03
16 A multistrategy machine learning approach to object recognitionThis work describes an innovative approach that combines machine learning and vision into an integrated system.
