A process-resource graph is a directed graph with m
resource nodes and n process nodes. A request edge is
directed from a process to a resource. An assignment edge
is directed from a resource to a process. A cycle in the
process-resource graph is a necessary and sufficient condition for...
The general problem of application development of interactive GUI applications has been addressed by toolkits, libraries, user interface management systems, and more recently domain-specific application frameworks. However, the most sophisticated solution offered by frameworks still lacks a number of features which are addressed by this research: 1) limited functionality --...
The purpose of this research is to design a high level language
(HLL) suitable for microprogramming. A top down design technique has
been adopted which makes the language design process simple and
accurate.
The primitive operations of a high level language for producing
emulators is shown to include special purpose...
Formal methods using text to specify abstract data types (ADTs) are powerful, but they require great effort and a high level of expertise. Visual programming languages present an alternative way of programming but are limited to building small programs. This research presents an approach for specifying ADTs using a combination...
The purpose of this project was to create a code generating software tool, which is one section of the Oregon SpeedCode Universe. The Code Generator automatically generates compilable source code to form working Macintosh applications. This source code provides a prototype for the actual final application. This is done with...
The task of designing and building the user interface portion of a Macintosh application is radically different than the same task on a more conventional computer with a conventional operating system. Just the fact that it is radically different makes it very time consuming to learn how to program this...
Development of graphical user interface (GUI) applications is difficult since the process can be both complicated and tedious. We propose a solution directed at reducing programming time and effort required to build a GUI application. Our solution is based on the Petri Network, the Oregon SpeedCode Universe (OSU) Application Framework,...
Several problems with user interface design and implementation have been identified: (1) user interfaces are difficult and time-consuming to design and implement; (2) most user interface management systems (UIMS) are themselves difficult to use by a programmer; (3) UIMS's have not been integrated with other tools that support structured design,...
The Server System/1 (SS/1) Design Editor is a graphical programming tool that provides a simple interface for object oriented parallel programming. Two difficult problems with parallel programming, partitioning, end visualization are addressed by the SS/1 Design Editor. An SS/1 program is structured using object oriented design concepts. This leads to...
Oregon SpeedCode Universe (OSU) is a rapid prototyping system which automates the production of applications from a description of the user interface. GraphLab is a domain-specific tool which deals with several major problems concerning OSU: (1) limited functionality, that is, lacking graphical capabilities in generated applications, (2) indirect approach to...
