A fundamental phase in software development deals with verifying that software behaves correctly. Although accurate testing can discover many wrong behaviours, formal software verification techniques can help in developing applications that dependably ...

Model checking is a powerful formal analytical approach to verifying software and hardware systems. However, general industrial adoption is far from widespread. Some difficulties include the inaccessibility of techniques and tools and the need for ...

Reliability of software depends not only on intrinsic factors such as its code properties, but also on extrinsic factors—that is, the properties of the environment it operates in. In an empirical study of more than 200,000 Windows users, we found that ...

This paper characterizes operational failures of a production Custom Package Good Software-as-a-Service (SaaS) platform. Events log collected over 283 days of in-field operation are used to characterize platform failures. The characterization is ...

The software of mechatronic systems interacts with the system's physical environment. In such systems, an incorrect software may cause harm to human life. As a consequence, software engineering methods for developing such software need to enable ...

Designing software systems with uncertainties, such as incomplete knowledge about changing system goals, is challenging. One approach to handle uncertainties is self-adaptation, where a system consists of a managed system and a managing system that ...

The execution of a concurrent Java program can deadlock if its threads attempt to acquire shared locks in cyclic order. The JVM permits such behaviour. Research has demonstrated that such deadlocks can be predicted through static analysis. It is also ...

Project schedules are essential for successfully carrying out software projects. To support manager’s decision making, many project scheduling algorithms have been developed in recent years for generating candidate project schedules. However, these ...

In this idea paper, we propose a novel way for improving the testing of program changes via symbolic execution. At a high-level, our technique runs two different program versions in the same symbolic execution instance, with the old version effectively ...

Recent work on workspace monitoring allows conflict pre- diction early in the development process, however, these approaches mostly use syntactic differencing techniques to compare different program versions. In contrast, traditional change-impact ...

Functional and non-functional requirements are becoming more and more complex, introducing ambiguities in the natural language specifications. A very broad class of such requirements are the ones that define quantitative properties of software systems. ...

Classical verification techniques rely on the assumption that the model of the system under analysis is completely specified and does not change over time. However, most modern development life-cycles and even run-time environments (as in the case of ...

Formal verification requires high performance data processing software for extracting knowledge from the unprecedented amount of data coming from analyzed systems. Since cloud based computing resources have became easily accessible, there is an ...

Software testing is the primary activity to guarantee some level of quality of software systems. In software testing, the role of test oracles is crucial: The quality of test oracles directly affects the effectiveness of the testing activity and ...

Our research aims to study and characterize the redundancy of software systems. Intuitively, a software is redundant when it can perform the same functionality in different ways. Researches have successfully defined several techniques that exploit ...

Software systems are often constructed by combining new and existing services and components. Models of such systems should therefore be compositional in order to reflect the architectural structure. We present herein an extension of the LTSA model ...

Atlas is a new software analysis platform from EnSoft Corp. Atlas decouples the domain-specific analysis goal from its underlying mechanism by splitting analysis into two distinct phases. In the first phase, polynomial-time static analyzers index the ...
