software product lines have potential to allow for mass customization of products. Unfortunately, the resulting, vast amount of possible product variants with commonalities and differences leads to new challenges in software testing. Ideally, every product variant should be tested, especially in safety-critical systems. However, due to the exponentially increasing number of product variants, testing every product variant is not feasible. Thus, new concepts and techniques are required to provide efficient SPL testing strategies exploiting the commonalities of software artifacts between product variants to reduce redundancy in testing. In this paper, we present an efficient integration testing approach for SPLs based on delta modeling. We focus on test case prioritization. As a result, only the most important test cases for every product variant are tested, reducing the number of executed test cases significantly, as testing can stop at any given point because of resource constraints while ensuring that the most important test cases have been covered. We present the general concept and our evaluation results. The results show a measurable reduction of executed test cases compared to single-software testing approaches. © 2015 ACM.

For every organization having a well secured network is the primary requirement to reach their goals. A network is said to be secure if it can protect itself from sophisticated attacks. Due to the rapid increase in the number of network users, security becomes the main challenge in the area of network field. Most security related threats target the layers of the OSI reference model. Sophisticated attack types such as Distributed Denial of Service (DDoS), Man-in-the-Middle and IP spoofing attacks are used to attack these layers. In this paper, we analyze most of the attack types that cause serious problems in computer networks and defense techniques to stop or prevent these attacks.

Background: Anecdotal evidence suggests that software applications are usually implemented using a combination of (programming) languages. Aim: We want to provide empirical evidence on the phenomenon of multi-language programming. Methods: We use data mining of 1150 open source projects selected for diversity from a public repository to a) investigate the projects for number and type of languages found and the relative sizes of the languages;b) report on associations between the number of languages found and the size, age, number of contributors, and number of commits of a project using a (Quasi-)Poisson regression model, and c) discuss concrete associations between the generalpurpose languages and domain-specific languages found using frequent item set mining. Results: We found a) a mean number of 5 languages per project with a clearly dominant main general-purpose language and 5 often-used DSL types, b) a significant influence of the size, number of commits, and the main language on the number of languages as well as no significant influence of age and number of contributors, and c) three language ecosystems grouped around XML, Shell/Make, and HTML/CSS. Conclusions: Multilanguage programming seems to be common in open-source projects and is a factor which must be dealt with in tooling and when assessing development and maintenance of such software systems.

Smart Home is indeed a broad concept which includes the techniques and systems applied to living spaces. While its main goal is to reduce the consumption of energy, it provides many benefits including living in comfort, security and increasing flexibility. Smart homes are achieved through networking, control and automation technologies. Since smart homes offer more comfort and security and provide novel innovative services, people with disabilities or the elderly can take the advantages and improve their life quality. However, for such novel services, an analytical infrastructure which can manage overall data flow provided by various sensors, understand anomalous behaviour, and make necessary decisions. In this study, for efficient data handling and visualisation, an integrated smart service approach based on the use of a smart vest is proposed. The smart vest plays a key role in the proposed system since it provides the main health parameters of the monitored person to the smart home service and enables tracking of the monitored person's location. The proposed system offers many benefits to both people with disabilities and the elderly and their families in terms of increased efficiency of health care service and comfort for the monitored person. It can also reduce the cost of health care services by reducing the number of periodical visits.

Integrated OR systems nowadays are closed and proprietary, so that the interconnection of components from third-party vendors is only possible with high time and cost effort. An integrated operating theatre with open interfaces, giving clinical operators the opportunity to choose individual medical devices from different manufacturers, is currently being developed in the framework of the BMBF (Federal Ministry of Education and Research) funded project *** [1]. Actual standards and concepts regarding technical feasibility and accreditation process do not cope with the requirements for modular integration based on an open standard. Therefore, strategies as well as service and device profiles to enable a procedure for risk management and certifiability are in the focus of the project work. Amongst others, a concept for User Interface Profiles (UI-Profiles) has been conceived in order to describe medical device functions and the entire user interface regarding Human-Machine-Interaction (HMI) characteristics with the aim to identify human-induced risks of central user interfaces. The use of standardized device and service profiles shall allow the manufacturers to integrate their medical devices in the *** network, without disclosing the medical devices' risk analysis and related confidential knowledge or proprietary information. © 2015 by Walter de Gruyter GmbH, Berlin/Boston 2015.

This position paper presents a concept on how the dynamic interconnection of medical devices in a service oriented architecture (SOA) can be secured based on formal interface descriptions. In the framework OpenSDC used in the research project *** formal interface descriptions are already used to model medical devices. The new approach is to use this formal descriptions to ensure the correct usage of the interface at runtime and to support developers in implementing medical devices with OpenSDC at the same time.

software engineering is an important development task in the automation domain due to the increasing number of embedded systems applied for controlling various system functions. In general, those automation systems are highly configurable, but share common functionality and engineering artifacts. If the knowledge about commonality and variability is not taken into account, this would result in a separate development process for each new system without reusing engineering artifacts. software product line engineering is a promising approach for the development of highly configurable automation systems explicitly exploiting the knowledge about commonality and variability. In addition to the specification of the problem space, i.e., all possible system configurations derivable from a feature model, reusable engineering artifacts are defined in the solution space by incorporating variability mechanisms. In this paper, we describe the re-engineering of an existing family of automation systems, a medical device for a novel radiotherapy, i.e., as a software product line. According to the concepts of software product line engineering, we describe (1) how we created a corresponding feature model for the problem space specification, and (2) how we integrated variability modeling into existing engineering artifacts. We provide details about our real-world case study and further explain the adaptation of its re-engineered version as dynamic software product line allowing for re-configuration at runtime. © Tagungsband - Dagstuhl-Workshop MBEES 2015: Modellbasierte Entwicklung Eingebetteter Systeme XI.

Today's integrated OR systems are closed and proprietary, so that the interconnection of components from third-party vendors is only possible with high time and cost effort. An integrated operating theatre with open interfaces, giving clinical operators the opportunity to choose individual medical devices from different manufacturers, would be advantageous for both hospital operators and small and medium-sized manufacturers of medical devices. Actual standards and concepts regarding technical feasibility and accreditation process do not cope with the requirements for modular integration based on an open standard. Therefore, strategies as well as device-and service-profiles to enable a procedure for risk management and certification capability are in the focus of the BMBF-funded OR. NET-project. The use of standardized device-and service-profiles shall allow the manufacturers to integrate their medical devices without disclosing the medical devices' risk analysis and related confidential expertise or proprietary information.

In this paper, we sketch how treating product lines as systems of possibly heterogeneous constraints allows one to elegantly and consistently manage product lines in terms of a product line of product lines. In fact, as will also be illustrated along our example scenarios, this leads to a framework for a consistent division of labour in an "easy for the many difficult for the few" fashion which supports correctness by construction. Central for this approach are our powerful model-based synthesis and code generation technologies, which turn systems of constraints into executable models or target code. © 2015 Copyright held by the owner/author(s).
