Our paper gives first answers on a fundamental question: how can the design of architectures of intelligent digital systems and services be accomplished methodologically? Intelligent systems and services are the goals of many current digitalization efforts today and part of massive digital transformation efforts based on digital technologies. Digital systems and services are the foundation of digital platforms and ecosystems. Digtalization disrupts existing businesses, technologies, and economies and promotes the architecture of open environments. This has a strong impact on new value-added opportunities and the development of intelligent digital systems and services. Digital technologies such as artificial intelligence, the Internet of Things, services computing, cloud computing, big data with analytics, mobile systems, and social enterprise networks systems are important enablers of digitalization. The current publication presents our research on the architecture of intelligent digital ecosystems and products and services influenced by the service-dominant logic. We present original methodological extensions and a new reference model for digital architectures with an integral service and value perspective to model intelligent systems and services that effectively align digital strategies and architectures with artificial intelligence as main elements to support intelligent digitalization.
Automatic classification of rotating machinery defects using Machine Learning (ML) algorithms
(2020)
Electric machines and motors have been the subject of enormous development. New concepts in design and control allow expanding their applications in different fields. The vast amount of data have been collected almost in any domain of interest. They can be static; that is to say, they represent real-world processes at a fixed point of time. Vibration analysis and vibration monitoring, including how to detect and monitor anomalies in vibration data are widely used techniques for predictive maintenance in high-speed rotating machines. However, accurately identifying the presence of a bearing fault can be challenging in practice, especially when the failure is still at its incipient stage, and the signal-to-noise ratio of the monitored signal is small. The main objective of this work is to design a system that will analyze the vibration signals of a rotating machine, based on recorded data from sensors, in the time/frequency domain. As a consequence of such substantial interest, there has been a dramatic increase of interest in applying Machine Learning (ML) algorithms to this task. An ML system will be used to classify and detect abnormal behavior and recognize the different levels of machine operation modes. The proposed solution can be deployed as predictive maintenance for Industry 4.0.
A fast way to test business ideas and to explore customer problems and needs is to talk to them. Customer interviews help to understand what solutions customers will pay for before investing valuable resources to develop solutions. Customer interviews are a good way to gain qualitative insights. However, conducting interviews can be a difficult procedure and requires specific skills. The current ways of teaching interview skills have significant deficiencies. They especially lack guidance and opportunities to practice. Objective: The goal of this work is to develop and validate a workshop format to teach interview skills for conducting good customer interviews in a practical manner. Method: The research method is based on design science research which serves as a framework. A game-based workshop format was designed to teach interview skills. The approach consists of a half-day, hands-on workshop and is based on an analysis of necessary interview skills. The approach has been validated in several workshops and improved based on learnings from those workshops. Results: Results of the validation show that participants could significantly improve their interview skills while enjoying the game-based exercises. The game-based learning approach supports learning and practicing customer interview skills with playful and interactive elements that encourage greater motivation among participants to conduct interviews.
Motto der Herbstkonferenz Informatics Inside 2020 ist KInside. Wieder einmal blicken Studierende inside und schauen sich Methoden, Anwendungen und Zusammenhänge genauer an. Die Beiträge sind vielfältig und entsprechend dem Studiengang human-centered. Es ist der Anspruch, dass sich die Themen um die Bedürfnisse der Menschen drehen und eingesetzte Methoden kein Selbstzweck sind, sondern am Nutzen für den Menschen gemessen werden.
The Twelfth International Conference on Advances in Databases, Knowledge, and Data Applications (DBKDA 2020) continued a series of events covering a large spectrum of topics related to advances in fundamentals on databases, evolution of relation between databases and other domains, data base technologies and content processing, as well as specifics in applications domains databases. Advances in different technologies and domains related to databases triggered substantial improvements for content processing, information indexing, and data, process and knowledge mining. The push came from Web services, artificial intelligence, and agent technologies, as well as from the generalization of the XML adoption. High-speed communications and computations, large storage capacities, and load-balancing for distributed databases access allow new approaches for content processing with incomplete patterns, advanced ranking algorithms and advanced indexing methods. Evolution on e-business, ehealth and telemedicine, bioinformatics, finance and marketing, geographical positioning systems put pressure on database communities to push the ‘de facto’ methods to support new requirements in terms of scalability, privacy, performance, indexing, and heterogeneity of both content and technology.
This book aims to explore various aspects of the use of moving images in fashion retail and fashion apparel companies in-store or online. The use of moving images is growing in numbers and in relevance for consumers. Films can be used in various forms by fashion businesses in traditional media like cinema or TV and in modern forms like in social media or moving images in high street stores.
The book provides a data-oriented analysis of the state-of-the-art with certain future outlooks. Additional areas of covering fashion in moving images, such as ‘fashion company identity films’ or ‘fashion and music videos’ are covered in order to get a more complete analysis from a consumer influenced perspective.
Immer deutlicher zeigt sich, dass die Modeindustrie nicht nur vor enormen Herausforderungen steht, sondern dass hiermit auch enorme Umbrüche einhergehen. Vor diesem Hintergrund interessiert uns nicht nur die Frage, was diese Herausforderungen sind, sondern auch, wie sie die Modeindustrie verändern. Unter dem Titel New fashion business wollen wir in diesem Band verstehen, welche Veränderungen bedeutsam sind und wie Unternehmen bereits darauf reagieren bzw. wie sie reagieren könnten.

Anhaltend erlebt die Künstliche Intelligenz (KI) eine Renaissance in vielen Branchen. Der Trend, komplexe Zusammenhänge in Daten zu erfassen und zu nutzen, hält an. Hierbei ist jedoch der Grundgedanke des Maschinellen Lernens basierend auf empirischen Daten nicht neu. Es bleibt nach wie vor die Herausforderung, erst ein oft auch interdisziplinäres Verständnis von komplexen Zusammenhängen für verschiedenste Anwendungs-Domänen zu gewinnen, um zum Beispiel KI sinnvoll zum Einsatz zu bringen. Als Besucher der Konferenz erwarten Sie Beiträge aus den unterschiedlichsten Bereichen. Hierzu gehören zum Beispiel Müdigkeitserkennungssysteme im Automobil, ein Tastsinn auch für Roboter, aber auch neue Ansätze zur Erzeugung und Nutzung von Virtuellen Realitäten für die Erprobung des autonomen Fahrens bis hin zur Simulation von Außenboardeinsätzen in der Raumfahrt.
Die dritte Ausgabe unseres Forschungsmagazins re:search widmet sich der Nachhaltigkeit. Welchen Preis zahlen wir für billige Kleidung? Wie weit ist die Nischenforschung zum Kunstfleisch? Wie kann man mit Hilfe von KI clever recyceln? Professorinnen und Professoren aller Fakultäten beschäftigen sich mit dem Thema Nachhaltigkeit – sei es im Bereich der Energieforschung, in der Künstlichen Intelligenz oder in der Ernährung. Ganz besonders brisant ist es in der Textil- und Modeindustrie. Wir produzieren nur noch wenig in Deutschland, haben deshalb schier unendliche Transportwege, die Herstellung ist oft mit einer hohen Umweltbelastung verbunden und der Konsum alles andere als nachhaltig.
