A novel approach to improve feature location by enhancing the corpus (i.e., source code) with static information is presented. An information retrieval method, namely Latent Semantic Indexing (LSI), is used for feature location. Adding stereotype information to each method/function enhances the corpus. Stereotypes are terms that describe the abstract role(More)
A highly efficient lightweight forward static slicing approach is presented and evaluated. The approach does not compute the program/system dependence graph but instead dependence and control information is computed as needed while computing the slice on a variable. The result is a list of line numbers, dependent variables , aliases, and function calls that(More)
An information retrieval technique, latent semantic indexing (LSI), is used to automatically identify traceability links from system documentation to program source code. The experiment is performed in the TraceLab framework. The solution provides templates and components for building and querying LSI space and datasets (corpora) that can be used as inputs(More)
A case study of three open source systems undergoing large adaptive maintenance tasks is presented. The adaptive maintenance task involves migrating each system to a new version of a third party API. The changes to support the migration were spread out over multiple years for each system. The first two systems are both part of KDE, namely KOffice and(More)
The high dimensionality of data presents a major issue in understanding and interpreting the results of classification learning. Among the various approaches that address this issue, parallel coordinates visualization has proven its capabilities to enhance investigation and comprehension of data dimension features especially when the number of dimensions is(More)
This paper describes the design and the evaluation for a simulation model for the dual curvature ultrasound phased array. The main goal of this simulation is to enhance the usage of dual curvature ultrasound phased array in ultrasound therapy with three dimensional phased arrays. In our simulation, focusing the total acoustic power within a specific phase(More)
