The RailChain project designed, implemented, and experimentally evaluated a juridical recorder that is based on a distributed consensus protocol. That juridical blockchain recorder has been realized as distributed ledger on board the advanced TrainLab (ICE-TD 605 017) of Deutsche Bahn. For the project, a consortium consisting of DB Systel, Siemens, Siemens Mobility, the Hasso Plattner Institute for Digital Engineering, Technische Universität Braunschweig, TÜV Rheinland InterTraffic, and Spherity has been formed. These partners not only concentrated competencies in railway operation, computer science, regulation, and approval, but also combined experiences from industry, research from acade...
Digital technology offers significant political, economic, and societal opportunities. At the same time, the notion of digital sovereignty has become a leitmotif in German discourse: the state’s capacity to assume its responsibilities and safeguard society’s – and individuals’ – ability to shape the digital transformation in a self-determined way. The education sector is exemplary for the challenge faced by Germany, and indeed Europe, of harnessing the benefits of digital technology while navigating concerns around sovereignty. It encompasses education as a core public good, a rapidly growing field of business, and growing pools of highly sensitive personal data. The report describes pathways to mitigating the tension between digitalization and sovereignty at three different levels – state, economy, and individual – through the lens of concrete technical projects in the education sector: the HPI Schul-Cloud (state sovereignty), the MERLOT data spaces (economic sovereignty), and the openHPI platform (individual sovereignty).
The “HPI Future SOC Lab” is a cooperation of the Hasso Plattner Institute (HPI) and industry partners. Its mission is to enable and promote exchange and interaction between the research community and the industry partners. The HPI Future SOC Lab provides researchers with free of charge access to a complete infrastructure of state of the art hard and software. This infrastructure includes components, which might be too expensive for an ordinary research environment, such as servers with up to 64 cores and 2 TB main memory. The offerings address researchers particularly from but not limited to the areas of computer science and business information systems. Main areas of research include cloud computing, parallelization, and In-Memory technologies. This technical report presents results of research projects executed in 2020. Selected projects have presented their results on April 21st and November 10th 2020 at the Future SOC Lab Day events.

Inhaltsangabe:Einleitung: Anlässlich der Internationalen Automobilausstellung 2003 in Frankfurt am Main erschien in bedeutenden deutschen Tageszeitungen und Publikumszeitschriften eine Sonderbeilage des Automobilherstellers Volkswagen mit dem Titel „Aus Liebe zum Automobil“. Auf insgesamt 20 Farbseiten erhielt der Betrachter nicht etwa einen Überblick über die aktuellen Modellreihen des Hauses mit expliziten Angaben über Ausstattungsvarianten, technische Details und Preise. Auch Versprechungen über Zuverlässigkeit, Fahreigenschaften und Raumangebot suchte man vergebens. Statt dessen konnte man auf den Doppelseiten im Inneren der Beilage kunstvolle, ästhetische Landschaftsaufnahmen...
Environmental informatics is a field of applied computer science that develops and uses the techniques of information processing for environmental protection, research and engineering. The multidisciplinary nature of environmental problems needs environmental informatics as a bridge and mediator between many disciplines and institutions. The present book presents a wide range of topics currently being pursued in the area, including basic methodological issues and typical applications. A significant number of recognised experts have contributed to the volume, discussing the methodology and application of environmental monitoring, environmental databases and information systems, GIS, modeling software, environmental management systems, knowledge-based systems, and the visualisation of complex environmental data. For scholarly and professional practitioners of environmental management who wish to acquire well-founded knowledge of environmental information processing and specialists in applied computer science who wish to learn more about the contribution of their field to the solution of our urgent environmental problems.
DE Um in der Schule bereits frühzeitig ein Verständnis für informatische Prozesse zu vermitteln wurde das neue Informatikfach Digitale Welt für die Klassenstufe 5 konzipiert mit der bundesweit einmaligen Verbindung von Informatik mit anwendungsbezogenen und gesellschaftlich relevanten Bezügen zur Ökologie und Ökonomie. Der Technische Report gibt eine Handreichung zur Einführung des neuen Faches. EN In order to impart an understanding of computer science processes at an early stage at school, the new computer science subject Digital World was designed for year 5, which combines computer science with application-related and socially relevant references to ecology and economics in a way that is unique in Germany. The Technical Report provides guidance on the introduction of the new subject.
Digitale Technologien bieten erhebliche politische, wirtschaftliche und gesellschaftliche Chancen. Zugleich ist der Begriff digitale Souveränität zu einem Leitmotiv im deutschen Diskurs über digitale Technologien geworden: das heißt, die Fähigkeit des Staates, seine Verantwortung wahrzunehmen und die Befähigung der Gesellschaft – und des Einzelnen – sicherzustellen, die digitale Transformation selbstbestimmt zu gestalten. Exemplarisch für die Herausforderung in Deutschland und Europa, die Vorteile digitaler Technologien zu nutzen und gleichzeitig Souveränitätsbedenken zu berücksichtigen, steht der Bildungssektor. Er umfasst Bildung als zentrales öffentliches Gut, ein schnell a...
