Current Projects
ARBAY
Internet marketplaces such as Amazon or eBay are dominating more and more areas of the retail trade as "digital checkpoints". One exception so far has been the trade with durable, highly varied and customizable consumer goods. The effect of the configurable product on the consumer's own four walls can only be checked after delivery. The ARBAY project brings the consultation and configuration of individualized goods into the living room. Virtual and augmented reality technologies are used in the project to create new digital distribution channels for highly varied goods. The aim is to develop a sales platform that extends the principle of known sales platforms for the sale of these goods. The main focus of the ISSE project is the development of a semantic product model as a basis for the platform.

Biotope
The aim of the project BioTope is to develop a basic technology and engineered methodology to facilitate the creation of emergent services that allow for self-adaptive system platforms. The rules of composition are not centrally and statically predetermined by the
Platform, but can be dynamically configured and demand-driven. This should be achieved and maintained in an Open IoT ecosystem that Integrates data and services to create processes to satisfy user requirements. The main motivation here is user requirements, which drives any new behaviour created in the system. The ecosystem tends to create the balance between user needs and provided data and services. All this is governed by system guarantees that ensures the correct flow of the ecosystem.

DevOpt
Software ecosystems are complex system groups of interacting, distributed individual systems that require continuous, autonomous optimization. In DevOpt we understand an emergent, distributed system as a three layers architecture: Local IoT ecosystems negotiate their work configuration / resource usage under framework conditions. A control layer can correct local decisions through comprehensive, distributed optimization. A DevOps layer enables analysis, maintenance and further development through human intervention.
DevOpt aims at the development of controlled emergent systems through distributed modelling, local negotiation of device configurations / resource usage, increased development efficiency through model-based design, as well as combination of emergence and DevOps. The demonstration / evaluation takes place as electric grid scenarios using self-learning predictive SmartMeters. The ISSE will implement a component-based emergence framework for the local layer and environments, which enables local optimization and mutual dynamic use of resources. Furthermore, the emergent integration should be monitored and optimized with regard to functional and non-functional requirements.

6RLogistics
Deutschland hat sich mit dem 2021 beschlossenen Klimaschutzgesetz zu einer Verschärfung der Klimaschutzvorgaben verpflichtet.[1] Die Förderung der Kreislaufwirtschaft stellt hierzu einen grundlegenden Baustein dar und ermöglicht die aktive Abfallvermeidung und Wiederverwendung sowie die Rückgewinnung von Materialien durch Recycling.[2] Großes Potenzial bieten in diesem Sinne Elektro- und Elektronikaltgeräten, EAG genannt, da hier mit einer wachsenden Menge in den nächsten Jahren gerechnet wird und die Produkte sich aufgrund ihres Aufbaus oftmals für die Wiederverwendung und Reparatur eignen.[3] Allein 2018 wurden in Deutschland pro Person 10,3 kg entsorgt, womit Deutschland über dem EU Durchschnitt liegt.[4] Dabei werden immer noch EAGs unsachgemäß im Haushaltsmüll entsorgt, was wiederum die sachgerechte Wiederverwertung und das Recycling unmöglich macht.[5] Das Projektvorhaben 6RLogistics greift diese Problematik auf und schafft mittels künstlicher Intelligenz und smarter Logistik Abhilfe bei der Verwertungsentscheidung und dem Transport bzw. der Entsorgung. Dabei erfasst die künstliche Intelligenz den Zustand des Produktes bei den Nutzern und wählte darauf basierend den geeigneten Verwendungszweck. Daran angeschlossen erfolgt der Transport des Produktes vom Nutzer zu den Verwertern. Es findet daher ein Pull-Effekt durch die Verwerter statt, bei der die Idee des „Abstellraums“ als dezentrales Waren- und Ersatzteillager genutzt wird. Hierdurch wird nicht nur die Sammelquote in Bezug auf EAGs erhöht, sondern auch die Wiederverwendungs- und Recyclingquoten der Geräte, womit ein aktiver Beitrag zu den Klimazielen durch die Reduktion von CO2-Emissionen, sowie die Energie- und Ressourceneinsparungen geleistet wird. In drei verschiedenen Use-Cases werden die Aspekte eines solchen Systems im Rahmen des Vorhabens auf verschiedenen Ebenen erprobt und die Teilsysteme getestet. Dabei werden sowohl die Rückführung bei Endnutzern und in Annahmestellen untersucht, als auch die Erkennung und Evaluierung im industriellen Kontext. Somit werden im Rahmen des Vorhabens neue Systematiken für die Warenlogistik und Wiedernutzung von Gütern erprobt, welche dadurch der Kreislaufwirtschaft einen Vortrieb leisten.

Life_Twin
The electronic products currently in use are designed for only short-lived use cycles and are contributors to the current increase in global waste volumes and excessive use of raw materials. [1] As a result, electrical and electronic products generate emissions that can be reduced through repair and reuse. However, emissions are also generated during the storage, sale and disposal of equipment. Particularly in view of global warming, these emissions represent a major potential for reduction. The aim of the project Life_TWIN is to investigate smart solutions for condition assessment and to identify opportunities for reuse, thereby reducingCO2 emissions. The project proposal within the funding line "Resource Efficiency in the Context of the Energy Transition" within the 7th non-nuclear funding program of the German Federal Ministry of Economics and Climate Protection (BMWK) is thus in direct line with other research projects to pave the way for the Circular Economy. Research into solutions for improving the condition monitoring of products plays a central role in this, as it enables damage and material fatigue to products to be detected. Digital twins are to be used in the project, which will enable the condition of products to be recorded and controlled.

HitchHikeBox
In addition to environmental and health damage caused by emissions such as noise, CO2, and air pollutants, the quality of life is also increasingly restricted by road traffic due to a large amount of land used (e.g., for roads, parking areas, loading/unloading areas). With the progressive growth in transportation, especially in commercial logistics transport, the situation has become even more acute in recent years. The development of technical, urban planning, and social concepts to satisfy society's mobility and logistical needs while also increasing environmental protection and urban quality of life is THE challenge of the next decade.
In the project HitchhikeBox, an intermodal hitchhike logistics system based on AI-based journey planning of self-organizing delivery boxes is to be developed. This is a technological platform for an integrated electric mobility and logistics system that enables reduced private/commercial trips while maintaining mobility and logistics, as well as reduced parking space requirements, by maximizing the efficiency of current vehicles without sacrificing flexibility. The main innovation of the project is bringing forth an automated, decentralized dispatching system for self-organized "intelligent" logistics boxes (HitchhikeBox) that enable intermodal Multi-Hop-Routing “hitchhiking” via local Micro-Hub-Depots. Moreover, it aims to increase the use of all-electric vehicles by participating regional vehicle operators and to take advantage of synergy benefits by bundling individual journeys that can be coordinated. The Institute for Systems and Software Engineering (ISSE) is developing a software solution for the “intelligent” reusable logistics box for its independent and automatic hitchhiking from an initial to the final point. This solution will have intelligent strategies for the execution of a transportation task. Also, the development and conceptual design of this dynamic-adaptive self-organizing system based on smart contracts.

5GCampusKIShuttle
Der neue 5G-Kommunikationsstandard spielt eine entscheidende Rolle für innovative Anwendungen, insbesondere im Bereich des autonomen Fahrens. Dieses Projekt zielt darauf ab, ein 5G-Campusforschungsnetz zu etablieren, um die Anforderungen des autonomen Fahrens auf Level 3-5 ohne Sicherheitsfahrer an Bord und stattdessen mit einer technischen Remote-Aufsicht (Leitstand) zu erfüllen. Gemäß dem Gesetz zum autonomen Fahren der Bundesrepublik, das am 28.7.2021 in Kraft getreten ist, ist erstmals die Möglichkeit geschaffen worden, autonomes Fahren auf Level 3 ohne Sicherheitsfahrer und mit einer Remote-Aufsicht (im Sinne von einem 5G Remote-Leitstand im Projekt) im Regelbetrieb umzusetzen. Für diesen 5G Remote-Leitstand muss ein 5G-Netzwerk etabliert werden, das die erforderlichen Safety und Security-Eigenschaften des 5G-Funkstandards erweitert, um die Qualität des Funknetzes während der Teleoperation vorherzusagen und das Netz vor Angriffen zu schützen.
Zudem sollen autonome Fahrzeuge in der Lage sein, komplexe Fahrumgebungen zu bewältigen, wie etwa schlecht einsehbare Kreuzungen. 5G-Infrauktursensorik kann hierbei unterstützen, indem sie einen Ersatz für den analogen Verkehrsspiegel bietet, wie er von menschlichen Fahrern genutzt wird. Schließlich muss ein betriebssicheres KI-basiertes Fahrsystem (5G Fail-Operational) mit Shadow-Mode entwickelt und über 5G mit der 5G-Infrastruktursensorik und dem 5G Remote-Leitstand zu einem integrierten 5G-basierten Mobilitäts- und Logistikdienstleistungssystem verbunden werden. Ein autonomer CampusShuttle wird als Demonstrationsbetrieb aufgebaut. Das 5G-Campusforschungsnetz wird als Plattform und Testfeld für laufende und zukünftige Forschungsprojekte genutzt und steht den beteiligten Instituten und Zentren zur Verfügung. Die Projektergebnisse können als Modell für den Aufbau autonomer Shuttles in anderen 5G-Reallaboren und Gebieten mit 5G-Netzversorgung dienen. Das Projekt wurde in der vierten Beiratssitzung des Verbundvorhabens 5G-Reallabor in der Mobilitätsregion Braunschweig-Wolfsburg vorgestellt und einstimmig positiv unterstützt. Dies zeigt die ausgezeichnete Einbettung des Projekts in die 5G Innovationsregion Braunschweig-Wolfsburg.

SafeWahr
Environmental perception systems of autonomous vehicles are nowdays using extensive AI-based algorithms. Established techniques and methods to proof correctness regarding safety are reaching its limits. Even if a lot of driving scenarios and millions of kilometers are used for testing, an overall safety assurance during design time is not possible. The goal for the project SafeWahr is to duly detect violations of safety critical specifications and uncertainities of AI-based environmental perception systems of autonomous vehicles. In case a violation was detected the autonomous vehicle will then continue its driving task with restricted functionality in a so called fail-operational mode.
One approach for handling situations, which are not known during design time is to partially shift the safety assurance to the operating time. Ultimately, some kind of "operation time certification" is aimed. For this purpose an operation time monitoring architecture for self-diagnosis will be developed in SafeWahr. Within this operation time monitoring architecture three types of monitors will be included: (1) A Situation Monitor, which determines if the current situation was considered during design time, (2) a Validity Monitor, which determines if the AI-based perception is safe regarding its results and (3) a Function Monitor, which determines if the target function acts corretly regarding safety specifications.

Methoden zur ODD Beschreibung
Verschiedene Gesetzesinitiativen sehen die Operational Design Domain (ODD) als Ausgangspunkt einer Entwicklung von Automated Driv-Fahrsysteme (ADS). In diesem Zusammenhang wird die ODD von mehreren Automotive OEMs als zentrale Wissensbasis nicht nur für die Systementwicklung und -validierung, sondern auch für sondern auch für die Analyse von Business Cases und für den Systembetrieb. Daher ist es für OEMs eine ODD entwickeln zu können, die in sich konsistent ist, ein zentrales Anliegen. Eine ODD Beschreibung ist in sich konsistent wenn es keine Widersprüche zwischen den ODD Constraints gibt.
Standard-Verifikationswerkzeuge, z.B. Solver für Satisfiability Modulo Theories (SMT), können verwendet werden, um die Konsistenz einer ODD-Beschreibung zu überprüfen Zusätzlich können solche Werkzeuge verwendet werden eine ODD Beschreibung gegenüber konkreten Fahrsituationen zu überprüfen um festzustellen welche Situationen für den Betrieb des ADS sicher sind. Allerdings ist es oft so, dass die Verwendung eines bestimmten Verifikationswerkzeugs umfangreiche Kenntnisse der formalen Spezifikations Sprache, die das jeweilige Werkzeug als Eingabe akzeptiert, erfordert.
Aktuelle Standardisierungsbemühungen, z.B. durch ASAM Arbeitsgruppe, empfehlen die Beschreibung einer ODD durch semi-formale Sprachen, z.B. auf Basis von YAML, um auch Stakeholder anzusprechen die kein Hintergrund in formalen Methoden haben. In diesem Projekt bauen wir ein Konzept für die Beschreibung einer ODD auf, das die Brücke einspannt zwischen den semi-formalen Sprachen, die durch aktuelle Standardisierungsbemühungen empfohlen sind, und der formalen Standardsprache, die für die Interpretation und Auswertung der ODD benötigt wird, einspannt. Dieses Konzept demonstrieren wir anhand von Beispielen aus der Industrie die durch ein Automobilhersteller im Rahmen des Projektes uns zur Verfügung gestellt wurden.

LogiSmile
Today’s increasing logistic operations constitute increasing challenges for traffic in urban areas. In addition to traffic congestion caused by logistic operations, safety problems are also getting increasingly critical. Aiming to tackle these challenges, the LogiSmile partners are piloting a fully autonomous delivery system in different pilot cities: Esplugues de Llobregat, Spain, Hamburg in Germany, and Debrecen in Hungary. This autonomous delivery system is realized based on the cooperation between an autonomous hub vehicle (AHV) and smaller robots, which are autonomous last-mile delivery devices (ADD). Furthermore, an additional remote back-end control center for managing the communication between the AHV and the ADD, acquiring the data while operating, and optimizing the fleet operations with efficient routing algorithms. As an NFF member, ISSE participates in the development of the remote back-end control center, aiming to provide fail-operational solutions in the case of critical situations that cannot be handled by the AHV autonomously.

Future Lab Mobility
The project of “Zukunftslabor Mobilität” (in English: Future Mobility Lab) focuses on the application-oriented research work by using different mobility-related technologies. In four well-defined interdisciplinary fields (Collaborative Research Fields (CRF 1-4)), potential environmentally and socially compatible mobility solutions such as connection of systems, human users and infrastructures relying on the digitalization technology will be investigated and developed, with consideration of concrete use cases about future mobility in Lower Saxony of Germany as well as related methods and approaches for the development of innovative mobility solutions.
In the scope of this project, TU Clausthal is involved together with other project partners in CRF 2, which focuses on relevant topics of smart mobility data handling. As known, the data plays a significantly important role as the basis of autonomous driving (CRF 1) and additionally as the precondition of the development and implementation of appropriate mobility services and corresponding business models (CRF 4). In CRF2, scientists from the research fields of communication technology, information and software engineering work closely together to develop methods to realize a safe and reliable data acquisition, evaluation and fusion of mobility data. For this purpose, the approaches for reliable (safety, security and privacy) data collection and processing, which fulfill the legal framework like DSGVO, will be developed and demonstrated with consideration of both phases for system development and operation. The approaches for the development of a reliable data architecture, methods and approaches for the standardization of data handling and fusion, as well as the assessment and assurance of data quality will be also developed and tested in the project.

The Limits to Growth – Sustainability and the Circular Economy (MOOC)
Project-Website: Link
In research, teaching, and technology transfer, the overarching theme for the Clausthal University of Technology, its guiding principle, is the Circular Economy. While degree-specific courses deal with selective aspects of the Circular Economy, there is a gap with respect to a course for all students that teaches the essential concepts and fundamentals of sustainability, environmental pollution, resource scarcity, and the Circular Economy.
The course “The Limits to Growth – Sustainability and the Circular Economy” aims to close this gap. As a general foundation course, there are no access restrictions. Furthermore, the course can be taken by Bachelor and Master students and PhD students. In order to accommodate a large number of international students, the course is conducted in English.
The Limits to Growth (LTG) course is open to all students of the Clausthal University of Technology as well as other organizations. Therefore, an adapted teaching format and appropriate technical support are required. The LTG course will be implemented as a Massive Open Online Course (MOOC), which scales traditional forms of knowledge transfer (slides, recordings, etc.) via an IT-driven infrastructure and expands them with additional technical features such as forums, quizzes and other forms of (semi-) automated tasks or tasks to be assessed via peer feedback. In addition, corresponding MOOC platforms offer participants interaction and networking opportunities and the possibility of asynchronous learning, in which students study according to their schedule. They are given access to all teaching and learning materials, which are discussed in regular meetings – followed by optional question-and-answer sessions to clarify any questions.
All teaching and learning materials, recordings, homework, tutorials, etc. are published under an open-source licence (CC-BY-SA-4.0) and are thus freely available as directly integrable teaching units or as a basis for further courses.

SoRec – Digitalisation of Sorting Processes for Fine-Grained, Metal-Containing Waste Streams in the Recycling Industry
Project-Website: https://www.sorec-greentech.de/
Closing material and resource cycles is an integral part of the circular economy. Many products (especially electronic devices) are becoming increasingly complex regarding their structure and raw materials. To recover raw materials, the products must be broken down into ever-finier grain sizes and subsequently sorted. In general, dry sorting processes achieve good sorting results in the fine particle size range with lower throughputs. However, when increasing the throughput, the quality of the sorting results decreases considerably. In order to operate profitably, sorting machines must work as close as possible to the tipping point between good quality and maximum throughput while also minimising maintenance downtimes.
The SoRec project focuses on digitalising sorting processes for fine-grained, metal-containing waste streams in the recycling industry. By installing state-of-the-art industrial line cameras and sensors, we are digitizing the conventional sorting method on a moving belt. With the help of advanced AI models and algorithms in deep learning and machine learning, our system can accurately detect materials on the conveyor belt, classify them based on size, shape, and color, and even find their precise edges. With the capability to identify multiple layers of materials, the AI model provides valuable density and volume estimation. To ensure real-time efficiency and control, we have integrated the AI model with powerful computer vision techniques, which handle crucial image processing tasks. This seamless collaboration between AI and computer vision allows us to estimate the belt’s speed and detect any anomalies, ensuring precise sorting and preventing belt misalignments. Our materials, measuring just 1 mm in size, demand meticulous attention to detail, necessitating high-level zoom capabilities for precise annotations. With this innovative AI-driven system, we are taking a significant step towards automating and optimizing the sorting process, enhancing productivity, and elevating the industry to new heights of accuracy and efficiency.

AI-based flood warning system for the city of Goslar
The project "AI-based flood warning system" is a practical application of AI forecasting systems to safety-critical areas. The application domain is the catchment area of Goslar with the existing sensor infrastructure and its historical data. The task of the artificial intelligence is to observe the current status of weather such as precipitation, soil moisture, solar radiation over a past period of time and put it in relation to the current water level in the settlement. A possible correlation is assumed, so that dangerous, sudden peaks can be predicted at an early stage. The forecasting method is thus a core element for the coordination of a series of structural measures for the prevention of sudden flooding events.

Der Einsatz von KI im Kontext der prädiktiven Instandhaltung von Abwasserkanälen birgt Vorteile, sowohl im Sinne der Kostenersparnis als auch der Vorbeugung von Totalausfällen und daraus ggf. resultierenden Verunreinigungen des Grundwassers. Ziel ist es hierbei, bisher analog ausgeführte Tätigkeiten, so beispielsweise die Klassifikation von Schäden am Kanal, in Zukunft automatisiert erfolgen zu lassen. Darauf aufbauend lässt sich insbesondere eine Strategie ableiten, mit der sich der zukünftige Instandhaltungsprozess optimieren lässt. Zum Zwecke der Nutzerfreundlichkeit wird zusätzlich ein 3D-Modell des gesamten Netzes entwickelt, mit der sich sowohl die Klassifikation, als auch die Prognose des Zustandes visuell einsehen lässt. Die geplanten Schritte hierbei reichen von der theoretischen Erarbeitung eines Konzepts, bis hin zu einem einsatzfähigen Prototypen. Die eingesetzten Techniken umfassen klassische statistische Methoden, bis hin zu maschinellen Verfahren im Sinne des Predictive Maintenance und der Klassifikation.

Harz water reservoir
In the north of Germany, the Harz, with its annual precipitation of 1200 mm on the Clausthal plateau and its storage capacity, through the numerous tailings ponds and dams, supplies regions as far away as Bremen with drinking water. Due to this importance in drinking water supply, but also due to the existing underground infrastructure of the mining heritage and due to its central and cross-border location, the Harz region is of outstanding water management importance in Germany. AI-supported water management can help to mitigate the extreme weather events that occur due to climate change, such as heavy rainfall events with flood disasters or long periods of drought. Possible solutions should both show the user options for action and make the use of conventional, numerical models more efficient and effective. The Harz region is to be developed as a digital twin and serve as a basis for the application of complex simulations over a wide area. The focus of the modelling is on an AI-hybrid model that combines both conventional and innovative approaches and thus generates added value in terms of water quality and quantity.

Foremost, the structuring and evaluation criteria of the possible applications of the AI are to be carried out. This evaluation shall be considered concerning scenarios or geoscientific questions. The result should be a transparent and explainable comparison, classification and evaluation of the possibility to apply and usefulness of machine learning methods in the field of geosciences. Thereby, research gaps in the geosciences shall be identified, and R&D needs shall be named. The essential use of AI will be made in interacting with a so-called expert system. One essential transparency criterion is that artificial intelligence will take over particularly time-consuming and repetitive tasks, but the human decision-maker should make the final decision in the so-called expert system.

Trink Extrem
The aim of the research project is to develop methods, precautionary concepts and transferable practical tools for extreme events for water supply companies and the water management administration. In this context, relevant sub-areas of water supply from water extraction and treatment to operation and water use are addressed, as are the different types of raw water: groundwater, spring water and surface water. In representative model regions of the German long-distance and surface water supply, an exemplary implementation takes place. This allows further long-distance and surface water suppliers or local water suppliers to adapt their respective different local requirements in a practical way. Ultimately, the project should also provide impulses for rule-making, e.g. in risk management and for cooperation with state authorities in extreme situations. The project should also raise awareness for the challenges of water supply during extreme events. A modern public relations work shall sensitize water supply companies with comparable challenges as well as interested end customers for the topic of extreme events and show the possible solutions developed in the project.

CircularLIB
This project is part of the CircularLIB research training group on the cycle-oriented production of lithium-ion batteries. In this program the three universities TU Braunschweig, TU Clausthal and Leibnitz Universität Hannover are cooperating with the Fraunhofer Institute for Surface Engineering and Thin Films IST.
The aim is to research a hybrid AI-based modeling approach for lithium-ion batteries. Recently, machine learning has also been increasingly used in the context of classical engineering disciplines. In particular, deep learning approaches provide fast and relatively accurate modeling approaches based on learning specific tasks from examples. This is of crucial interest especially in the context of high-dimensional complex systems, where the underlying physics is not fully known or the computational effort for simulation with conventional numerical methods is high. Another aspect driving the use of deep learning approaches is the need for fast models that can be used in iterative tasks such as optimization and control. However, data-driven models are typically black-box approaches that are developed based only on data and do not explicitly incorporate physical knowledge or constraints into model development. This can result in such models lacking robustness and accuracy, especially with limited training data.
Recent advances in physically-informed machine learning have led to a number of approaches that are well suited for solving various types of partial differential equations (PDEs). This project aims to develop models based on both data and available physical knowledge for lithium-ion batteries using physically informed machine learning techniques that allow for a hybrid AI-based modeling approach.
