The European Computing Conference offers a unique forum for establishing new collaborations. This volume presents a collection of papers covering recent advances in computer engineering, systems theory, and computational methods.

Software testing has been considered so important that organizations can assign teams only for testing activities. Testing is an important activity to ensure software quality. Tests are usually run several times to certify that code ma- tenance did not accidentally insert defects into working parts of the software. In such situations, test teams shall be able to estimate the required effort to execute test cases in its schedules and to request more resources or negotiate deadlines when necessary. When regarding model-based testing approaches that we use in our documented Integrated and Optimized Software Testing methodology (IOSTP) [14], a high number of test cases can be automatically generated. As team resources are limited, it may be not practical to execute all generated test cases. Their complexity usually determines the effort required to execute them and it can be used for planning test resources and test suites. Several software development estimation models have been proposed over the years. However, these models do not estimate the effort for executing a given test suite, since their estimations are based on software development complexity instead of its test planning, test case design and test execution complexity. According to our reading of the literature (e. g. [514]), ''best practices'' in model-based effort estimation include: Local calibration (or LC); i. e. using local data to set two special tuning parameters; Stratification; i. e. given a database of past projects, and a current project to be estimated, restrict local calibration to just those records from similar projects.

Klappentext

These two volumes are from proceedings of the European Computing Conference. The conference focus was in the areas of Systems Theory, Applied Mathematics, Simulation, Numerical and Computational Methods, and Parallel Computing, which was held September 25-27, 2007 in Athens, Greece.

Each volume is divided into sections that focus on different topics. The first volume includes seven sections with topics ranging from neural networks and applications to educational software and e-learning. The second volume has eight sections covering topics such as computer applications in power systems and theoretical approaches in information science. All the chapters are self-contained and peer reviewed.
