This paper proposes to use SDL block diagrams, UML class diagrams, and UML behavior diagrams like collaboration diagrams, activity diagrams, and statecharts as a visual programming language. We describe a modeling approach for flexible, autonomous production agents, which are use…
In search for improved software quality and high productivity, software reuse has become a key research area. One of the most promising reuse approaches is product families. However, current practices in requirements engineering do not support product families. This paper describ…
One of the characteristics of object-oriented software is the complex dependency that may exist between classes due to inheritance, association and aggregation relationships. Hence, where to start testing and how to define an integration strategy are issues that require further i…
Requirements engineering (RE) is concerned with the identification of the goals to be achieved by the envisioned system, the operationalization of such goals into services and constraints, and the assignment of responsibilities for the resulting requirements to agents such as hum…
This distribution is counter-intuitive for at least two reasons. First it would seem “obvious” that the numbers drawn from a list generated from widely different arbitrary processes would have roughly equally probabilities for the digits 1 and 9 to be first digits. This is not no…
Another concept of Third Eye is the tracing state. Tracing state is a set of event types generated in that state, other event types are filtered out and not reported. The system is always in a specific tracing state. Tracing states correspond to specifications. A program specific…
We explore the use of multivariate visualization techniques to support a new approach to test data selection, called observation-based testing. Applications of multivariate visualization are described, including: evaluating and improving synthetic tests; filtering regression test…
There are three interdependent factors that drive our software development processes: interval, quality and cost. As market pressures continue to demand new features ever more rapidly, the challenge is to meet those demands while increasing, or at least not sacrificing, quality. …
To compute accurate information efficiently for programs that use pointer variables, a program analysis must account for the fact that a procedure may access different sets of memory locations when the procedure is invoked under different callsites. This paper presents light-weig…
New approaches propose to deal with the tangling of logical units by extending the object-oriented language to support module (de)composition along more than one dimension of concern. The tutorial will briefly survey Aspect-Oriented Programming (@@@@ectJ tool), Adaptive Programmi…
Aspect-Oriented Programming (AOP) is intended to ease situations that involve many kinds of code tangling. This paper reports on a study to investigate AOP's ability to ease tangling related to exception detection and handling. We took an existing framework written in Java™, the …

Research results indicate that (as usual in software engineering) these question can only be answered with reference to each specific application context and that diversity is no “silver bullet”. But diversity is an attractive option, made more interesting by current trends like …
Current automatic test execution techniques are sensitive to changes in program implementation. Moreover, different test descriptions are required by different testing tools. As a result, it is difficult to maintain or port test descriptions. To address this problem, we developed…
The Internet creates new opportunities for component distribution. Infrastructure for dynamic, Web-based composition of software components appears to be a very impelling need. This demonstration focuses on a Web-based system that supports dynamic component composition.
Algorithmic cost estimation in the context of software evolution is being addressed as part of the FEAST/2 project with encouraging results from an industrial case study.
Using only traditional techniques the implementation of concerns like exception handling, multi-object protocols, synchronization constraints, and security policies tends to be spread out in the code. The lack of modularity for these concerns makes them more difficult to develop …

Doctoral research in software engineering is a major source of new ideas and of key importance in training scientists for the information technology community. The rapid evolution of information technology is challenging the relevance of doctoral programs in software engineering.…
Graphical animation is a way of visualizing the behavior of design models. This visualization is of use in validating a design model against informally specified requirements and in interpreting the meaning and significance of analysis results in relation to the problem domain. I…
