Merlo (c) Abstract: One of the undesired effects of software evolution is the proliferation of unused components, which are not used by any application. As a consequence, the size of binaries and libraries tends to grow and system maintainability tends to decrease. At the same time, a major trend of today's software market is the porting of applications on hand-held devices or, in general, on devices which have a limited amount of available resources. Refactoring and, in particular, the miniaturization of libraries and applications are therefore necessary. We propose a Software Renovation Framework (SRF) and a toolkit covering several aspects of software renovation, such as removing unused objects and code clones, and refactoring existing libraries into smaller more cohesive ones. Refactoring has been implemented in the SRF using a hybrid approach based on hierarchical clustering, on genetic algorithms and hill climbing, also taking into account the developers' feedback. The SRF aims to monitor software system quality in terms of the identified affecting factors, and to perform renovation activities when necessary. Most of the framework activities are language-independent, do not require any kind of source code parsing, and rely on object module analysis. The SRF has been applied to GRASS, which is a large open source Geographical Information System of about one million LOCs in size. It has significantly improved the software organization, has reduced by about 50% the average number of objects linked by each application, and has consequently also reduced the applications' memory requirements.

Abstract

"Abstract. Background. Seroma formation after axillary dissection remains the most common early sequel to breast cancer surgery. Different surgical approaches have been performed to reduce seroma collection. Therefore, we aimed to assess the outcome of patients operated on using an ultrasound scalpel according to a standardized operative technique before accepting it as a routine procedure.. . Methods. A randomized controlled trial was designed to compare the outcome of patients undergoing breast surgery and axillary dissection using either standard scalpel blades, scissors, ligations, and electrocautery or the ultrasound scalpel only. Each arm of the trial consisted of 30 patients.. . Results. A statistically significant benefit in terms of axillary and chest wall drainage volume, the number of axilla seromas, intraoperative bleeding, and hospitalization stay was recorded in the harmonic scalpel group. No significant differences were found between the 2 groups in terms of operative time. Finally, no postoperative hematoma, wound infections, and chest wall seroma were observed.. . Conclusions. The use of the harmonic scalpel was shown to reduce the magnitude of seromas in axilla and hospitalization stay. The harmonic scalpel can be used alone in axillary dissection with a safe and effective hemostasis. Our results must be confirmed by larger series.. . "

Abstract

A resource usage view consists of models that are important assets to analyze and control usage of hardware resources such as processors and memory elements. In this paper, we present the application of a top-down approach to construct a resource usage view using actual system runtime information. The models in this view help to address the concerns of a resource usage viewpoint providing information in terms of system-specific architecture and design execution elements such as execution scenarios, tasks, software components, processes, and threads. As part of our validation, constructing a resource usage view of an MRI system, a representative large software-intensive system, we observed that the constructed models for this view provide useful overviews and insights for practitioners to describe part of the system execution architecture and especially to analyze and evaluate the use of hardware resources in a. top-down fashion.

34. An Approach for Search Based Testing of Null Pointer Exceptions

Abstract

Uncaught exceptions, and in particular null pointer exceptions (NPEs), constitute a major cause of crashes for software systems. Although tools for the static identification of potential NPEs exist, there is need for proper approaches able to identify system execution scenarios causing NPEs. This paper proposes a search-based test data generation approach aimed at automatically identify NPEs. The approach consists of two steps: (i) an inter-procedural data and control flow analysis—relying on existing technology—that identifies paths between input parameters and potential NPEs, and (ii) a genetic algorithm that evolves a population of test data with the aim of covering such paths. The algorithm is able to deal with complex inputs containing arbitrary data structures. The approach has been evaluated on to test class clusters from six Java open source systems, where NPE bugs have been artificial introduced. Results show that the approach is, indeed, able to identify the NPE bugs, and it outperforms random testing. Also, we show how the approach is able to identify real NPE bugs some of which are posted in the bugtracking system of the Apache libraries.
