Network-Based Analysis of Software Change Propagation

The object-oriented software systems frequently evolve to meet new change requirements. Understanding the characteristics of changes aids testers and system designers to improve the quality of softwares. Identifying important modules becomes a key issue in the process of evolution. In this context, a novel network-based approach is proposed to comprehensively investigate change distributions an...

Characterizing electron temperature gradient turbulence via numerical simulation

Numerical simulations of electron temperature gradient ETG turbulence are presented that characterize the ETG fluctuation spectrum, establish limits to the validity of the adiabatic ion model often employed in studying ETG turbulence, and support the tentative conclusion that plasma-operating regimes exist in which ETG turbulence produces sufficient electron heat transport to be experimentally ...

Supporting Impact Analysis and Change Propagation in Software Engineering Environments

Impact analysis and change propagation are among the major issues of software change management. In this paper, we introduce an approach to providing impact analysis and change propagation support as an integral part of software engineering environments, so that they can be applied during bath software development and maintenance. In this approach, the activities are carried out on the original...
