    Certifying Energy Efficiency of Android Applications
    (Proceedings of the 28th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2014) Meier, Johannes; Ostendorp, Marie-Christin; Jelschen, Jan; Winter, Andreas
    While smartphone and tablet functionality is increasing, battery runtime goes down. Both users and software developers are not always aware of the energy consumed by applications. Without this information, users cannot choose energy-efficient apps to prevent battery drain. Awareness of energy consumption would also entice app developers to implement more energy-efficient apps to remain competitive. This paper presents a certification process and corresponding Android tool support for comparing apps regarding energy efficiency. It is demonstrated using notepad apps.

    ELVIZ: A Query-Based Approach to Model Visualization
    (Modellierung 2014, 2014) Ostendorp, Marie-Christin; Jelschen, Jan; Winter, Andreas
    Visualization is an important technique for understanding and exploring complex models. To be useful, visualizations have to be specifically tailored towards the visualization task and the analyzed model. Many standard charts or graph-based visualizations exist, but need to be mapped to the concepts of the model under study. Existing model visualization tools often have predetermined visualization kinds and content, impeding reuse of standard visualizations for various purposes, or lacking the ability to flexibly map source model concepts to different visualization elements. This paper presents ELVIZ („Every Language Visualization”), an approach to visualization, generic regarding both the source model, and the kind and content of the visualization. ELVIZ applies model-driven engineering techniques both to transform arbitrary source models into the desired visualization models, and to generate said model transformations from a query-based mapping of source model concepts to visualization concepts. This cleanly decouples source and visualization meta-models, allowing to reuse and combine standard visualizations for various source models. The ELVIZ approach is applied to scenarios from software visualization in software evolution and measuring energy consumption of mobile applications, using different kinds of visualizations.

    Flexible Software Support for Mobility Services
    (INFORMATIK 2017, 2017) Akyol, Ali; Halberstadt, Jantje; Hebig, Kimberly; Jelschen, Jan; Winter, Andreas; Sandau, Alexander; Gómez, Jorge Marx
    Demographic change and growing urbanization are essential reasons for the increasing demand for mobility in rural areas in Germany. Municipalities in sparsely populated counties are confronted with the problem of providing a basic supply of public mobility services. Especially for rural areas, established public transport means have to be complemented by additional, new, and innovative mobility services. NEMo (Sustainable satisfaction of mobility demands in rural regions) pursues the development of sustainable and innovative mobility services based on tailored business models for rural areas. Traveler information systems are enhanced to handle a range of active and passive mobility services in a very flexible way. Within this paper, three flexible cases are demonstrated. The SENSEI framework for software evolution provides improved software support by adding and modifying capabilities of the existing services to re-orchestrate and re-implement mobility services.
