Presently, mHealth becomes increasingly important in supporting patients in their everyday life. For example, diabetes patients can monitor themselves by the use of their smartphones. On the other, clinicians as well as medical researchers try to exploit the advantages of mobile technology. More specifically, mHealth applications can gather data in everyday life and are able to easily collect sensor or context data (e.g., the current temperature). Compared to clinical trials, these advantages enable mHealth applications to gather more data in a rather short time. Besides, humans often behave atypically in a clinical environment and, hence, mHealth applications collect data in a setting that reflects the daily behavior more naturally. Hitherto, many technical solutions emerged to deal with such data collection settings. Mobile crowdsensing is one prominent example in this context. We utilize the latter technology in a multitude of large-scale projects to gather data of several chronic disorders. In the TrackYourTinnitus project, for example, we pursue the goal to reveal new medical insights to the tinnitus disorder. We learned in the realized projects that a sophisticated API must be provided to cope with the requirements of researchers from the medical domain. Notably, the API must be able to flexibly deal with requirement changes. The work at hand presents the elicited requirements and illustrate the pillars on which our flexible and generic API is built on. Although we identified that the maintenance of such an API is a challenging endeavor, new data evaluation opportunities arise that are promising in the context of chronic disorder management.

The term "Cyber Physical System" (CPS) has been used in the recent years to describe a system type, which makes use of powerful communication networks to functionally combine systems that were previously thought of as independent. The common theme of CPSs is that through communication, CPSs can make decisions together and achieve common goals. Yet, in contrast to traditional system types such as embedded systems, the functional dependence between CPSs can change dynamically at runtime. Hence, their functional dependence may cause unforeseen runtime behavior, e.g., when a CPS becomes unavailable, but others depend on its correct operation. During development of any individual CPS, this runtime behavior must hence be predicted, and the system must be developed with the appropriate level of robustness. Since at present, research is mainly concerned with the impact of functional dependence in CPS on development, the impact on runtime behavior is mere conjecture. In this paper, we present AirborneCPS, a simulation tool for functionally dependent CPSs which simulates runtime behavior and aids in the identification of undesired functional interaction.

The paper describes the problem of collecting, merging, and sharing information from workshops and conference notes in order to achieve better cooperation between stakeholders, thus improving collaboration during product development. We provide an overview of apps for Android and iOS devices that can facilitate this problem. We tested these apps on their recognition of handwritten and printed text and their integration into existing services, but none of them met all desired requirements. We propose an approach that includes a self-adaptive part to improve handwritten text recognition as well as a context-sensitive part to facilitate the integration into existing systems in the context of the Smart RE framework.

Natural language requirements often ignore unexpected or off-nominal behaviors (ONBs), which can result in catastrophic accidents in safety-critical systems. While some existing techniques can help identify ONBs, most of them are not systematic and algorithmic, and also they require a lot of human effort. In this paper, we propose an algorithmic and systematic approach for knowledge acquisition of ONBs in componentbased systems using a modified Apriori algorithm. Our approach analyzes component state transition rules to identify dependencies among components, which are used to group components that are dependent on each other into component sets. These sets are used for analysis of possible ONBs. We conducted an empirical study to evaluate our approach. Our results indicate that the component sets generated using our approach are able to expose missing dependencies and ONBs with much less human effort when compared to CCM.

The Internet of Things (IoT) has become a major technological revolution. Evaluating any IoT advancements comprehensively is critical to understand the conditions under which they can be more useful, as well as to assess the robustness and efficiency of IoT systems to validate them before their deployment in real life. Nevertheless, the creation of an appropriate IoT test environment is a difficult, effort-intensive, and expensive task; typically requiring a significant amount of human effort and physical hardware to build it. To tackle this problem, emulation tools to test IoT devices have been proposed. However, there is a lack of systematic approaches for evaluating IoT emulation environments. In this paper, we present a requirements-based framework to enable the systematic evaluation of the suitability of an emulated IoT environment to fulfil the requirements that secure the quality of an adequate test environment for IoT.

In the past three editions of RESACS, submitted papers and workshop discussions have proven useful to presenting authors and attending audience alike, resulting in new impulses in shaping this still novel and wide-spread field. For the fourth edition of RESACS, the tradition of RESACS was continued. In a highly interactive workshop the arising challenges in the emergent field of self-adaptive, collaborative, and cyber physical systems were discussed, positioned, and addressed. Thought-provoking and highly constructive discussions among a broader audience and presenters jointly identified properties of these types of system, what their properties entail, which challenges emerge due to these properties, and how traditional, contemporary, and novel approaches might address these challenges for requirements engineering in particular, but also software engineering in general. We hope that the results of the RESACS workshop will spawn research ideas, and standardization of terminology in SAS and CPS research, validate existing research avenues, foster empirical studies, and facilitate collaboration between industry and academia for software engineering as a whole.

Functional Safety (FS) has become a major consideration during the development of embedded and reactive systems. When incorporating functional safety into a system under development, the engineer must be cognitive of not just system requirements, but safety requirements as well. These safety requirements are typically derived from an initial set of hazard and risk assessments. While there are various means of performing these assessments, there is a particular classification of hazards, based on undesired combination states that may be overlooked by other techniques. In this paper, we propose a technique that addresses these hazards, using Undesired Combination States Templates (UDCST). The technique has been conceived to accommodate the constraints on time and cost typically encountered in industry. We demonstrate the technique with two real world applications.

(Context and Motivation) Non-Functional Requirements (NFR) play a crucial role during the software development process. Currently, Non-Functional Requirements considered to be more important than Functional Requirements and can determine the success of the software system. Non-Functional Requirements can be very complicated to understand due to their subjective manner and especially their conflicting nature. Many approaches and techniques have been introduced to manage the conflicts between multiple Non-functional Requirements and to analyze the trade-off in costs and benefits between the alternative solutions that satisfy them. (Problem) Self-Adaptive Systems tends to change its behavior and configurations due to the changes in its environment. Current solutions might not be suitable for the current situations, because current approaches managing Non-Functional Requirements trade-off stops managing them during the system runtime. (Approach and Objective) In this paper, we investigated the trade-offs between multiple Non-Functional Requirements in Self-Adaptive Systems. We fragmentized the NonFunctional Requirements and its alternative solutions in form of Multi-entity Bayesian network fragments. As a result, when changes occur, our system creates a situation specific Bayesian network to measure the impact of the system's conditions and environmental changes on the Non-Functional Requirements satisfaction. Furthermore, it dynamically decides which alternative solution is suitable for the current situation.

Assembly, configuration, maintenance, and repair processes in cyber-physical systems (e.g., a press line in a plant) comprise a multitude of complex tasks, whose execution needs to be controlled, coordinated and monitored. Amongst others, a process-centric guidance of users (e.g. service operators) is required, taking the high variability in the assembly of cyber-physical systems (e.g. press line variability) into account. Moreover, the tasks to be performed along these processes may be related to physical components, sensors and actuators, which need to be properly recognized, integrated and operated. In order to digitize cyber-physical processes as well as to guide users in a process-centric way, therefore, we suggest integrating process management technology, sensor/actuator interfaces, and augmented reality techniques. The paper discusses fundamental requirements for such an integration and presents an approach for process-centric user guidance that combines context and process management with augmented reality enhanced tasks. For evaluation purposes, we analyzed the cyber-physical processes of pharmaceutical packaging machines and implemented selected ones based on the approach. Overall, we are able to demonstrate the usefulness of context-aware process management for the flexible support of cyber-physical processes in the Industrial Internet of Things.
