TL;DR: An orchestrated survey of the most prominent techniques for automatic generation of software test cases, reviewed in self-standing sections, aimed at giving an introductory, up-to-date and (relatively) short overview of research in automatic test case generation.

TL;DR: There is little consensus on what constitutes a software ecosystem, few analytical models of software ecosystems exist, and little research is done in the context of real-world ecosystems, according to this systematic literature review of software ecosystem research.

TL;DR: A method in which in-browser key translation allows a software-as-a-service application to run with confidentiality from the service provider to survey approaches to protecting data from a cloud infrastructure provider.

TL;DR: A theoretical framework is created that provides a holistic view of technical debt comprising a set of technical debts dimensions, attributes, precedents and outcomes, as well as the phenomenon itself and a taxonomy that describes and encompasses different forms of the technical debt phenomenon.

TL;DR: Various aspects relevant to innovation measurement ranging from definitions, measurement frameworks and metrics that have been proposed in literature and used in practice are explored.

TL;DR: A novel log-linear regression model based on the use case point model (UCP) to calculate the software effort based on use case diagrams is presented and demonstrates that the MLP model can surpass the regression model when small projects are used, but the log- linear regression model gives better results when estimating larger projects.

TL;DR: A study of two systematic mapping studies is presented to evaluate the reliability of mapping studies and point out some challenges related to this type of study in software engineering.

TL;DR: This exploratory study sets out to uncover the concepts that practitioners in a large software organization use in the prioritization process and the practices that they deem good, and brings a rich analysis of cases in agile and distributed contexts, from a vendor's perspective.

TL;DR: A larger nationwide view on software testing practices among practitioners in Canada is conducted with a revised list of questions in 2010, and the importance of testing-related training is increasing.

TL;DR: This work depreciate N-way and endorse LOO validation for assessing effort models because of their generated B&V values and runtimes and in terms of reproducibility, LOO removes one cause of conclusion instability.

TL;DR: This study was not able to confirm the model developed in the previous study, but was able to shed additional light regarding agile software development in former Yugoslavia countries from SEE region as a reference region for investigating outsourced projects done in agile way.

TL;DR: Experimental results show that the proposed color image watermarking is not only robust against common image processing operations such as filtering, JPEG compression, histogram equalization, and image blurring, but also robust against the geometrical distortions.

TL;DR: Experimental results show that the proposed high-capacity reversible data hiding method achieves both high capacity and high image quality.

TL;DR: A novel framework is introduced that provides a structured process that supports elicitation of security and privacy requirements and the selection of a cloud provider based on the satisfiability of the service provider to the relevant security and Privacy requirements.

TL;DR: A cost-effective travel recommender system-iTravel-thus is developed to provide tourists with on-tour attraction recommendation and three data exchange methods that allow users to effectively exchange their ratings toward visited attractions are proposed.

TL;DR: This work describes an approach to predict failures based on log files using Random Indexing and Support Vector Machines that is very reliable in predicting both failures and non-failures.

TL;DR: A manual paper and pencil game to reinforce and teach the application of SCRUM in undergraduate computing programmes complementing theoretical lectures and offers a low-budget alternative to complement traditional instructional strategies for teaching SCRum in the classroom.

TL;DR: Experimental results show that the proposed prediction-error expansion based reversible data hiding by using a new predictor based on partial differential equation outperforms some state-of-the-art methods.

TL;DR: A well-established prediction approach based on time series ARIMA (Autoregressive Integrated Moving Average) modeling is presented as an alternative solution to address the SRGMs' limitations and provide more accurate reliability prediction.

TL;DR: A histogram shifting method for image reversible data hiding testing on high bit depth medical images by exploiting the high correlation for smooth surface of anatomical structure in medical images.

TL;DR: The experimental results show that the proposed scheme outperforms Chen and Tsao (2011)'s scheme significantly in visual quality, and improves the contrast of Chen andTsao ( 2011)'s threshold scheme.

TL;DR: A mapping study of about 120 primary studies is presented, to provide an overview of the research efforts on Gang of Four (GoF) design patterns and suggests that design pattern research can be further categorized to research on GoF patterns formalization, detection and application and on the effect of GoFpatterns on software quality attributes.

TL;DR: Assessment of the diffusion and relevance of software modelling and MD techniques in the Italian industry, understand the expected and achieved benefits, and identify which problems limit/prevent their diffusion.

TL;DR: The findings suggest that many safety techniques enforce a creative and systematic process by applying guide-words and structuring the results in worksheets, while security techniques tend to integrate system models with security models.

TL;DR: Compared with traditional symmetric histogram, the asymmetric error histogram reduces the amount of shifted pixels, thus improving the watermarked image quality, and a complementary embedding strategy is proposed by combining the maximum and minimum error histograms.

TL;DR: In this paper, the authors investigated the potential of code smells to reflect system-level indicators of maintainability and found that code smells are not good indicators for comparing the maintainability of systems differing greatly in size.

TL;DR: A new robust and reversible watermarking approach for the protection of relational databases based on the idea of difference expansion and utilizes genetic algorithm (GA) to improve watermark capacity and reduce distortion.

TL;DR: In this paper, a survey about the use of UML modeling and model-driven approaches for the design of embedded software in Brazil is presented, where the authors investigate technical, organizational, and social aspects.

TL;DR: Improvements to logic-based test design and change the way the ROR mutation operator is defined in existing and future mutation systems to incorporate relational operator replacement from mutation are presented.

TL;DR: The theme of 'SBSE for the cloud', formulating cloud computing challenges in ways that can be addressed using SBSE is developed.
