Abstract

The use of drones, a.k.a. unmanned aerial vehicles (UAVs) as a flying radio access network (RAN) is currently gaining significant attention. It holds promises as a complement to classical fixed infrastructure by allowing ultra flexible deployments, with use cases ranging from disaster recovery scenarios to improving the performance and coverage of the network. Beyond obvious challenges within regulatory, control, navigation, and operational domains, the deployment of autonomous flying-RANs also come with a number of exciting new research problems such as the issue of autonomous real-time placement of the drones in non-trivial propagation scenarios (i.e. scenarios where the optimal placement is not just dictated by a trivial geometry or statistical argument due to shadowing effects, e.g. in cities). We present several different approaches, lying at the cross-roads between machine learning, signal processing, and optimization. Some approaches involve the reconstruction of a city map from sampled radio measurements which can have application beyond the realm of communications.

Kurzfassung:

Die Leitidee der Siegener Lehrer(innen)bildung ist es, die angehenden Lehrerinnen und Lehrer zu einem reflektierten Handeln in Lehr-Lern-Situationen zu befähigen. Die Umsetzung dieser Leitidee erfordert eine starke Aktivierung der Lehramtsstudierenden in den Lehrveranstaltungen.
In unseren Vorlesungen, Übungen und Seminaren wurden verschiedene aktivierende Elemente und didaktische Prinzipien für eine aktivierende Lehre zur Förderung einer bewussten Haltung eingesetzt.
Beispielhaft für diesen Ansatz wird das Seminar „Schüler handeln, forschen und entdecken“ vorgestellt und diskutiert werden. Darin konzipieren Studierende Mathematik-Projekte, die mit Lerngruppen in der Siegener MatheWerkstatt durchgeführt werden, und analysieren anschließend  die Lehr-Lern-Prozesse. In dieser praxisorientierten Auseinandersetzung mit mathematischen Inhalten und der Gestaltung von Lernarrangements lernen die Studierenden, ihr Handeln und ihre Erfahrungen mathematikdidaktisch zu reflektieren.
Präsentiert werden das Siegener Leitbild für die Lehrer(innen)bildung sowie die unterschiedlichen Planungsdimensionen des Seminars anhand von Erlebnissen und Analysen der Studierenden.

Abstract

With the advent of every improving information technologies, science and engineering is being being evermore guided by data-driven models and large-scale computations.  In this setting, one often is forced to work with models for which the nonlinearities are not derived from first principles and quantitative values for parameters are not known.

With this in mind, I will describe an alternative approach formulated in the language of combinatorics and algebraic topology that is inherently multiscale, amenable to mathematically rigorous results based on discrete descriptions of dynamics, computable, and capable of recovering robust dynamic structures.

To keep the talk grounded, I will discuss the ideas in the context of modeling of gene regulatory networks.

Abstract

The main idea of this strategy is based on the essential textbook of pedagogy Orbis sensualium pictus which was written according to Komenský’s belief that the school should be a game. It was first published in Nürnberg in 1658. He believed, contrary to the teaching practices at the time, that the pupils should be able to teach learned matter not only to renounce mechanically but to understand what they were learning. He, therefore, provided a textbook with some illustrations so that it would be captivating for the children. It was about biology (living and inanimate nature), theology and man, something that can now be called the foundations of social sciences.

Modern times have brought new opportunities to implement this strategy.

For example, using simple computer games for practicing and verifying the student’s knowledge. During the lecture, several computer games created for this purpose will be presented. Games are primarily designed to teach automation and programming in MATLAB software at university.

They are created in the way that the data about the matter are read from an external file. This file is enough to be edited and used for any subject of the study program. In the lecture, there will also be introduced several electronic aids facilitating the teaching of work with graphics programs and programs in the office at secondary schools in the Czech Republic. All these games and utilities were rated by students using questionnaires after the completion of the courses, and these results will be presented, too.

Abstract: In October 2017, ISO/IEC JCT1 SC29/WG11 MPEG and ITU-T SG16/Q6 VCEG have jointly published a Call for Proposals on Video Compression with Capability beyond HEVC and its current extensions. It is targeting at a new generation of video compression technology that has substantially higher compression capability than the existing HEVC standard. The responses to the call are evaluated in April 2018, forming the kick-off for a new standardization activity in the Joint Video Experts Team (JVET) of VCEG and MPEG, with a target of finalization by the end of the year 2020. Three categories of video are addressed: Standard dynamic range video (SDR), high dynamic range video (HDR), and 360° video. While SDR and HDR cover variants of conventional video to be displayed e.g. on a suitable TV screen at very high resolution (UHD), the 360° category targets at videos capturing a full-degree surround view of the scene. This enables an immersive video experience with the possibility to look around in the rendered scene, e.g. when viewed using a head-mounted display. This application triggers various technical challenges which need to be addressed in terms of compression, encoding, transport, and rendering. The talk summarizes the current state of the complete standardization project. Focussing on the SDR and 360° video categories, it highlights the development of selected coding tools compared to the state of the art. Representative examples of the new technological challenges as well as corresponding proposed solutions are presented.

Title: The CyPHER Model for End-to-End Hybrid Systems Engineering

Abstract: The notion „Industry 4.0“ emphasises a new level for the organisation and control of the complete value added chain stretching over the life cycle of products and their production systems. A key aspect is the integration of the real world and its virtual counterpart concerning models for complex products and for complex, adaptive production processes. This requires the systematic development of concurrent adaptive systems of hybrid dynamic systems (aka cyber-physical systems).

In the talk I will emphasise a model for end-to-end systems engineering comprising structural and behavioural aspects as well as refinement, simulation and verification. Structurally, the model employs block types adopted from conceptual models and constraints that can be both extended to capture integrated continuous and discrete components. Behaviourally, the model is grounded in concurrent hybrid abstract state machines. The model can be used for the systematic step-by-step modelling of products, equipment of processes, thus contributing to a method for „Industry 4.0 by Design“.

Title: Spatio-temporal Reasoning and Decision Support for Industrial Automation

Abstract: This talk presents work on cloud-based decision support systems for industrial automation and gives an overview on my related activities in this field such as software/system architecture and formal system descriptions. A focus is on spatio-temporal reasoning and semantic descriptions of system artifacts such as digital twins.

Title: Increasing efficiency employing sensors, smart data and user engagement

Abstract: As the integration of the Internet and physical reality increases (e.g. as in the „Internet of Things“), analytical and sensor-based systems and services tend to transform quantitative input into knowledge representations with shared, transparent structures for improved interoperability, as envisioned and practiced on the Semantic Web.On the other hand, efficiency is a key characteristic of production systems, and its implementation requires an easy integration and use of information coming from heterogeneous agents and systems, deriving semantically correct decisions, planning and executing processes, advanced sharing and adaptation capacities supported by semantic rules, and effective end-user engagement. I present these settings and instruments in the application areas of energy efficiency, smart offices and factories, and digital workplaces, and demonstrate their evaluation within real industrial products, real life data and services, and real end users. Further, I outline my perspective on future development of the addressed area, particularly in the directions of cognitive computing and explainable AI.

Title: Digitization of Future Production Systems Using Enterprise Modeling Methods

Abstract: For the digitization of future production systems, two core aspects need to be aligned. These are a. the requirements issued from the side of management in terms of new, technology-based business models and the life-cycle of value creation, and b. the capabilities and results provided by prospective intelligent, cyber-physical systems and according resources. To achieve this knowledge-intensive alignment, it is reverted to IT-based enterprise modeling methods. These modeling methods permit to integrate the knowledge of all relevant stakeholders for designing innovative production systems using formal and semi-formal semantic structures. In addition, they act as direct interfaces to technical systems, e.g. for configuring autonomous systems, for performing data analysis, or for the execution of simulations. Most recently, the application of such enterprise modeling methods has been described for the simulation of industrial business processes in a research project for agent oriented zero defect multi-stage manufacturing as well as for the design of IT environments for cyber-physical systems in the construction industry.

Titel: Wissensbasierte Methoden für den Entwurf und die Optimierung von Produktionssystemen

Kurzfassung: Universelle Such- und Optimierungsverfahren sind heutzutage in der Lage, reale Anwendungsprobleme mit Hunderttausenden von Variablen und mehreren Millionen Randbedingungen automatisiert zu lösen. Diese enorm hohe Skalierbarkeit ist dem Einsatz von ausgereiften allgemeinen Lösungsalgorithmen in Verbindung mit der Verfügbarkeit von effizienten Implementierungen zu verdanken. Darüber hinaus bilden moderne Methoden der Wissensrepräsentation die Grundlage für die kompakte und transparente Beschreibung der zu lösenden Anwendungsaufgaben. Effektive Werkzeuge für die Modellierung und Verarbeitung von Wissen stellen somit gleichermaßen Grundvoraussetzungen für die flexible Einsatzbarkeit und die allgemeine Akzeptanz von hochautomatisierten Lösungsprozessen dar. Mein Vortrag beschreibt und illustriert die praktische Umsetzung entsprechender wissensbasierter Methoden anhand von komplexen betrieblichen Anwendungen in den Bereichen Logistikmanagement, Personalplanung und Produktionsoptimierung.

Titel: Lösung eines Flottenoptimierungsproblems mit strukturierten Zeitfenstern für eine der weltweit größten Supermarktketten

Kurzfassung: Heutzutage bieten alle großen Lebensmittelhändler Online-Shopping-Services an, bei denen die Kundinnen und Kunden auf der Website des Supermarkts die gewünschten Lebensmittel sowie ein passendes Lieferzeitenfenster auswählen. Das Ziel unseres gemeinsamen Forschungsprojekts mit einer der weltweit größten Supermarktketten war es, einen stabilen und schnellen Optimierungsansatz zu entwerfen, der in der Lage ist, effiziente Fahrtrouten für eine große Anzahl von Kundinnen und Kunden und Fahrzeugen in Echtzeit zu bestimmen. Effizientere Touren sparen dabei nicht nur Geld, sondern sie erlauben es auch, zusätzliche Kundinnen und Kunden zu beliefern und bei jeder Bestellung mehr verfügbare Zeitfenster anzuzeigen, was zu einer höheren Kundenzufriedenheit führt. Unser Optimierungsansatz verbesserte die Effizienz der Routen verglichen mit dem vorherigen System der Supermarktkette um fast 10%, wodurch jährliche Kostensenkungen in Millionenhöhe erzielt werden konnten. Konzeption und Planung des zukünftigen Forschungsportfolios: Mein vorrangiges Ziel in diesem Bereich ist es ein anspruchsvolles und zukunftsorientiertes, international sichtbares Forschungsprogramm im Bereich Industrie 4.0 aufzubauen und voranzutreiben sowie den Transfer der Forschungsresultate in die betriebliche Praxis sicherzustellen. Von den in der Ausschreibung genannten methodischen Forschungsschwerpunkten decke ich mit meiner bisherigen Forschung insbesondere jenen des Automated Plannings ab. Allerdings ergaben sich im Rahmen meiner Forschungs- und Lehrtätigkeit auch zahlreiche Berührungspunkte mit den Bereichen Multi Agent Systems, Machine Learning und Autonomous Adaptive Systems. Zur Lösung von in der Praxis auftretenden Forschungsfragen, insbesondere für Problemlösungsansätze in Produktion und Supply-Chain-Netzwerken, ist es meiner Erfahrung nach oftmals erforderlich Ansätze und Methoden verschiedener Bereiche (z.B. Künstliche Intelligenz, heuristische Suchverfahren, Simulationstechniken, neuronale Netzwerke, …) miteinander zu kombinieren und zu integrieren. Daher würde aus meiner Sicht der zu besetzenden Professur auch eine wichtige Funktion als Schnittstelle und Bindeglied zwischen den bereits an der AAU (insbesondere natürlich an der technischen Fakultät) und an der TU Graz etablierten relevanten Forschungsschwerpunkten und den involvierten Industriepartnern zukommen.
