- KonferenzbeitragArchitecting for Sustainability(EnviroInfo 2022, 2022) Lago, Patricia; Greefhorst, Danny; Woods, EoinSustainability is becoming an increasingly important topic. Information Technology (IT) is an important factor for sustainability; it consumes a substantial, and growing, part of the world supply of energy, but it can also enable significant insights and improvements related to sustainability. These factors need to be taken into account in the design of IT systems, meaning that we need to architect for sustainability. This paper provides insights into the experience and beliefs of IT practitioners and researchers into current and desired practices of architecting for sustainability. It reports on the results of three workshop sessions with practitioners and researchers, providing insight into the state of research and practice.
- KonferenzbeitragBiomaterials for Prototyping in HCI(Mensch und Computer 2024 - Workshopband, 2024) Nicolae, Madalina; Roussel, Vivien; Koelle, Marion; Lefez, Claire; Roudaut, Anne; Nittala, Aditya Shekhar; Huron, Samuel; Teyssier, Marc; Steimle, JürgenWhile prototyping is a widespread practice among researchers, creating sustainable, functional devices remains challenging due to the limited range of available tools and materials. We present several approaches to sustainable prototyping of functional devices. Our methods range from using bio-based and bio-degradable materials as sustainable alternatives to biologically growing electronic substrates. These methods enable a new class of interactive devices that integrate electronic components with sustainable materials. Our research on Interactive Bioplastics [1] introduces a DIY approach for producing conductive bioplastics that are compatible with digital fabrication techniques. Furthermore, [2] introduces an integrated fabrication framework for sustainable soft shape-changing interfaces made of bioplastics. Finally, our work on Biohybrid Devices [3] showcases how the biological growth of living bio-materials--such as Bacterial Cellulose--can be used as assembling and embedding process for electronics. In addition to presenting various artifacts, we highlight the processes introduced by our fabrication frameworks [1-3] and engage the audience in discussions about the life-cycle phases of producing artifacts, promoting a critical reflection of sustainable practices in prototyping.

- KonferenzbeitragImproving food processing through integration of artificial intelligence in the drying process: a perspective(42. GIL-Jahrestagung, Künstliche Intelligenz in der Agrar- und Ernährungswirtschaft, 2022) Raut, Sharvari; von Gersdorff, Gardis; Schemminger, Jörg; Adolphs, Julian; Sturm, BarbaraThe agricultural value chain in general and food processing specifically are facing challenges at multiple levels (social, ecological, financial). Within the European Union, Food and Beverage (F&B) is the biggest economic sector with more than 99 % being small and medium enterprises (SMEs). Due to the lack of financial flexibility, SMEs are generally disadvantaged for implementation and integration of process and resource efficiency, thus hindering the development of advanced processing methods and in turn the production of high quality products. Additionally, as per the Sustainable Development Goals 2 and 12, it is important to improve food and nutritional security globally, through sustainable agriculture and food production methods. Therefore, it is essential to develop innovative solutions that are not only affordable but also sustainable. Within the food processing chain, drying is one of the oldest and most frequently implemented processing method, for preserving food products, reducing post-harvest losses and increasing the food and nutritional status. As simple as it may seem, drying is rather a complex process, which, if not optimized on a system level, results in (1) significant quality degradation and (2) resource wastage. Additionally, as most food products undergo at least partial drying, optimisation of this process will evidently help improve and optimise the food processing chain. In this context, concepts such as „Smart Food Factory“ and „Industry 4.0“ recognise the need for intelligent processing methods that facilitate the production of tailored final product quality. Recently, there has been significant advancement from the information and communications technology domain due to methodologies such as Internet of things (IoT), Cloud-Computing, and Artificial Intelligence (AI), which has led to a rapid development of digitalisation in the F&B sector. Studies indicate that AI methodologies such as fuzzy logic and artificial neural networks are helpful tools to resolve problems within the drying process. Additionally, integration of machine learning models with AI methodologies can also allow for real time optimisation and control of the drying system. To that end, this study aims to conduct an in-depth review on the current state of AI applications that have been integrated within the convective drying process and provide a future outlook for the development of intelligent drying systems which simultaneously cater for improved food quality, energy and resource efficiency.
- TextdokumentAn instant matching algorithm in the context of ride-hailing applications, using isochrones and social scoring(INFORMATIK 2021, 2021) Eilers, Malte; Hempen, Simon; Frers, Sebastian; Stahr, Benjamin; Hölscher, Natalia Hölscher; Bürmann, Paula; Janßen, Christian; Marx-Gómez, JorgeRide-sharing nowadays is a term most people have heard about. It is an efficient way to reduce both climate detrimental emissions and the overall traffic within large cities. A key aspect of ride-sharing is to match drivers and passengers according to a set of attributes. By matching people based on static and dynamic settings such as social preferences, this paper shows a fast and efficient approach for solving this problem. As a key difference to other solutions the core of the developed instant matching algorithm is built up on isochrones. These are used to match trips on specific geographical constraints, like the maximum detour and time until a passenger’s pickup. Furthermore, social metrics allow optimization based on individual preferences in the users trip selection. The

Die Ergebnisse bieten erste Einblicke in die Gestaltung von Technologien, die Generation Z für Umwelt- und Nachhaltigkeitsthemen mobilisieren können.
- WorkshopbeitragSetting up a long term evaluation environment for interactive semi-public information displays(Mensch und Computer 2023 - Workshopband, 2023) Koch, Michael; Fietkau, Julian; Stojko, LauraHuman-computer interaction research increasingly focuses on the long-term evaluation of real-world field deployments. When dealing with innovative solutions and when asking for the possibility to do action research in the deployment, fitting real-world deployments are hard to find – and access to these deployments is hard to obtain. We decided to invest in setting up and managing a long-term deployment of an interactive large information screen solution at our university, which includes several displays. In this paper, we briefly report about the installation – the CommunityMirror Network – as well as its functionality and operations management.
- Zeitschriftenartikel“Show-Me” — Ein ambientes Informationssystem zur Reduktion des Wasserverbrauchs(i-com: Vol. 10, No. 2, 2011) Kappel, Karin; Grechenig, ThomasDer weltweite Wasserverbrauch steigt stetig, während die existierenden Süßwasserressourcen immer geringer werden. Aus diesem Grund ist es unerlässlich, sich auch über den täglichen Wasserverbrauch Gedanken zu machen und neuartige Lösungen in diesem Bereich anzuwenden, um insgesamt zu einer Verbrauchsreduktion beizutragen. Ein ausgezeichneter Ansatzpunkt ist dabei die tägliche Dusche, die für eine Vielzahl von Menschen ein wichtiges Ritual darstellt. Je nach Badarmatur oder Duschgewohnheit wird so jeden Tag eine große Menge an Wasser — meist sogar unbewusst — verbraucht. Die Dusche birgt daher ein dementsprechendes Einsparungspotential. Um nachhaltiges Verhalten zu fördern und eine permanente Verhaltensänderung herbeizuführen, hat sich Feedback laut diversen Studien aus unterschiedlichen Bereichen bewährt. Eine Erweiterung des Feedbacks in Form von subtilem Feedback mit Hilfe von Licht, ermöglicht es den Benutzer auf seinen persönlichen Wasserverbrauch aufmerksam zu machen und stimuliert bz...
- TextdokumentSmartOS: An OS Architecture for Sustainable Embedded Systems(Tagungsband des FG-BS Frühjahrstreffens 2022, 2022) Scheipel, Tobias; Batista Ribeiro, Leandro; Sagaster, Tim; Baunach, MarcelThe number of embedded devices is growing, and so are the concerns about dependability and sustainability. However, the life-span of modern devices is commonly very short, due to their lack of long-term maintainability in both hardware and software. This yields an increased amount of e-waste, as the individual devices are commonly very cheap and can therefore easily be replaced in case of (partial) obsolescence. In this work, we show an operating system architecture which is designed to make embedded systems more sustainable and prepared for long-term use. To do so, we implement a general basic architecture alongside extended concepts and special features within the operating system. Our approach is based on hardware/software co-design and the opportunity to update software as well as hardware in a modular way at runtime. Therefore, logic reconfiguration of the host platform, dynamic software composition and integration, as well as formal methods for verification and portability are supported.
