However, the current challenge is to decide on whether to reuse an EV battery or to recycle it after its first use. This paper theoretically investigates these areas i.e., recycle and reuse. It was found that there are several commercially used recycling processes and also some are under research to regain maximum possible materials and quantity. The concept of reusing (second life) of the battery is promising because, at the end of the first life, batteries from EVs can be used in several applications such as storing energy generated from renewable sources to support the government grid. However, the cost and life-cycle analysis (LCA) demonstrated that there are several aspects involved in battery reuse applications. Henceforth, one LCA generalised method cannot provide an optimal approach for all cases. It is important to have a detailed study on each of the battery reusing applications. Until then, it is safe to say that reusing the battery is a good option as it would give some time to recycling companies to develop cost and energy-efficient methods.}, language = {en} } @article{LauschTaklaSchweiger2021, author = {Lausch, Jonas and Takla, Monir and Schweiger, Hans-Georg}, title = {Crush characteristics of flat-plate discontinuous carbon composites}, volume = {147}, pages = {106431}, journal = {Composites Part A: Applied science and manufacturing}, publisher = {Elsevier}, address = {Amsterdam}, issn = {1359-835X}, doi = {https://doi.org/10.1016/j.compositesa.2021.106431}, year = {2021}, language = {en} } @article{GeisbauerWoehrlKochetal.2021, author = {Geisbauer, Christian and W{\"o}hrl, Katharina and Koch, Daniel and Wilhelm, Gudrun and Schneider, Gerhard and Schweiger, Hans-Georg}, title = {Comparative Study on the Calendar Aging Behavior of Six Different Lithium-Ion Cell Chemistries in Terms of Parameter Variation}, volume = {14}, pages = {3358}, journal = {Energies}, number = {11}, publisher = {MDPI}, address = {Basel}, issn = {1996-1073}, doi = {https://doi.org/10.3390/en14113358}, year = {2021}, abstract = {The degradation of lithium-ion cells is an important aspect, not only for quality management, but also for the customer of the application like, e.g., scooters or electric vehicles. During the lifetime of the system, the overall health on the battery plays a key role in its depreciation. Therefore, it is necessary to monitor the health of the battery during operation, i.e., cycle life, but also during stationary conditions, i.e., calendar aging. In this work, the degradation due to calendar aging is analyzed for six different cell chemistries in terms of capacity degradation and impedance increase and their performance are being compared. In a new proposed metric, the relative deviations between various cells with the exact identical aging history are being analyzed for their degradation effects and their differences, which stands out in comparison to similar research. The capacity loss was found to be most drastic at 60 °C and at higher storage voltages, even for titanate-oxide cells. LiNiMnCoO2 (NMC), LiNiCoAlO2 (NCA) and Li2TiO3 (LTO) cells at 60 °C showed the most drastic capacity decrease. NMC and NCA cells at 60 °C and highest storage voltage did not show any open circuit voltage, as their current interrupt mechanism triggered. The effect of aging shows no uniform impact on the changes in the capacity variance when comparing different aging conditions, with respect to the evaluated standard deviation for all cells. The focus of this work was on the calendar aging effect and may be supplemented in a second study for cyclic aging.}, language = {en} } @article{RieglerWintersbergerRieneretal.2019, author = {Riegler, Andreas and Wintersberger, Philipp and Riener, Andreas and Holzmann, Clemens}, title = {Augmented Reality Windshield Displays and Their Potential to Enhance User Experience in Automated Driving}, volume = {18}, journal = {i-com: Journal of Interactive Media}, number = {2}, publisher = {De Gruyter}, address = {Berlin}, issn = {2196-6826}, doi = {https://doi.org/10.1515/icom-2018-0033}, pages = {127 -- 149}, year = {2019}, language = {en} } @article{FrisonWintersbergerRiener2019, author = {Frison, Anna-Katharina and Wintersberger, Philipp and Riener, Andreas}, title = {Resurrecting the ghost in the shell: a need-centered development approach for optimizing user experience in highly automated vehicles}, volume = {2019}, journal = {Transportation Research Part F: Traffic Psychology and Behaviour}, number = {65}, publisher = {Elsevier}, address = {Amsterdam}, issn = {1873-5517}, doi = {https://doi.org/10.1016/j.trf.2019.08.001}, pages = {439 -- 456}, year = {2019}, language = {en} } @article{HasirliogluRiener2019, author = {Hasirlioglu, Sinan and Riener, Andreas}, title = {A General Approach for Simulating Rain Effects on Sensor Data in Real and Virtual Environments}, volume = {5}, journal = {IEEE Transactions on Intelligent Vehicles}, number = {3}, publisher = {IEEE}, address = {New York}, issn = {2379-8904}, doi = {https://doi.org/10.1109/TIV.2019.2960944}, pages = {426 -- 438}, year = {2019}, language = {en} } @article{KundingerYalavarthiRieneretal.2020, author = {Kundinger, Thomas and Yalavarthi, Phani Krishna and Riener, Andreas and Wintersberger, Philipp and Schartm{\"u}ller, Clemens}, title = {Feasibility of smart wearables for driver drowsiness detection and its potential among different age groups}, volume = {16}, journal = {International Journal of Pervasive Computing and Communications}, number = {1}, publisher = {Emerald}, address = {Bingley}, issn = {1742-7371}, doi = {https://doi.org/10.1108/IJPCC-03-2019-0017}, pages = {1 -- 23}, year = {2020}, language = {en} } @article{SchneiderKempf1999, author = {Schneider, Doris and Kempf, Klaus}, title = {Der Aufbau der neuen bayerischen Fachhochschulbibliotheken - eine Erfolgsgeschichte}, volume = {27}, journal = {Bibliotheksforum Bayern}, number = {1}, publisher = {K.G.

To achieve both a high classification performance and a classification system that can be implemented on a microcontroller with limited computational resources, a two-stage design process is applied.

Forward-looking sensors (radar, lidar and cameras) have the technical capability to already provide important (pre-)crash information, such as the position of contact, relative crash velocity and overlap (width of contact) before the crash occurs. Future safety systems can improve crash mitigation with sophisticated vehicle safety strategies based on this information. One such strategy is an early activation of restraint systems compared with conventional passive safety systems. These integrated safety systems consist of a combination of predictive forward-looking sensors and occupant restraint systems (airbags, belt tensioners, etc.) to provide the best occupant safety in inevitable crash situations. The activation of the restraint systems is the most critical decision process and requires a very robust validation system to avoid false activation. Hence, the information provided by the forward-looking sensor needs to be highly reliable. A validation sensor is required to check the plausibility of crucial information from forward-looking sensors used in integrated safety systems for safe automated and autonomous driving. This work presents a CFRP-based (carbon-fiber-reinforced plastic) validation sensor working on the principle of change in electrical resistance when a contact occurs. This sensor detects the first contact, gives information on impact position (where the contact occurs) and provides information on the overlap. The aim is to activate the vehicle restraint systems at near T0 (time of first contact). Prototypes of the sensor were manufactured in house and manually and were evaluated. At first, the sensor and its working principle were tested with a pendulum apparatus. In the next stage, the sensor was tested in a real crash test. The comparison of the signals from the CFRP-based sensor with presently used crash sensors in the vehicle highlights its advantages. The crash event can be identified at 0.1 ms after the initial contact. The sensor also provides information on impact position at 1.2 ms and enables a validation of the overlap development. Finally, a possible algorithm for the vehicle safety system using forward-looking sensors with a validation sensor is described.}, language = {en} } @article{KimStegerKotaketal.2019, author = {Kim, Woong-Ki and Steger, Fabian and Kotak, Bhavya and Knudsen, Peter V.

In this study, three system designs were investigated, to compare different solutions to deal with pressure differences and condensation: (1) a sealed battery system, (2) an open system and (3) a battery system equipped with a pressure compensation element (PCE). These three designs were tested under two conditions: (a) in normal operation and (b) in a maximum humidity scenario. The amount of the condensation in the housing was determined through a change in relative humidity of air inside the housing. Through PCE and available spacing of the housing, moisture entered into the housing during the cooling process.

Among the available bioenergy technologies, biogas production via biodegradation and anaerobic digestion is a widely applied approach, not only to produce biofuels but also to manage industrial and domestic organic waste. Within the biogas production, a sufficient mixing of the organic mass is a crucial step to ensure high biogas yields by bacteria and enzymes. Measurements of the electric power consumption of biogas plants revealed that the electrical energy demand of the stirrer system has a high share of the total electricity consumption of a biogas plant. Investigations on real biogas digesters to optimize the mixing process are cost and time intensive. Therefore, laboratory prototypes and computational simulations represent promising alternatives to analyse and improve the efficiency of mixing systems. In this paper, a computational fluid dynamics (CFD) model is presented, which is applied to commercial stirring systems. The case of two propeller stirrers, located in diametrically opposite positions in a tank filled with ca. 1400 m3 of substrate is described in detail. For the simulation, the rheology of the fluid is adapted to a biomass with 12 wt \% dry matter content and obeying the non-Newtonian generalized Ostwald-de Waele power law. The developed simulation procedure considers the rotation angle of each propeller and its height. A total of 441 mixing configurations are calculated and evaluated in terms of the technical benefit.

To ensure the consistent quality of laboratory learning, an accurate comparison between the results of simulated experiments and practical hands-on experiments is required.

Application Design: To avoid interference of factors other than laboratory mode on the learning, laboratory instructions and experimental interfaces ensured identical execution of the experiments in the compared modes. Using a counterbalanced methodology, the two laboratory modes alternated by the session, while the experimental procedures remained constant regardless of the respective modes.

Several machine learning algorithms for binary classification were applied in user-dependent and independent tests. Results provide evidence that the non-intrusive setting achieves a similar accuracy as compared to the medical-grade device, and high accuracies (>92\%) could be achieved, especially in a user-dependent scenario.

Clinical assessment tools show that patients experiencing sensorimotor CIPN symptoms not only do they have to cope with loss in autonomy and life quality, but CIPN has become a key restricting factor in treatment. CIPN incidence poses a clinical challenge and has lacked established and efficient therapeutic options up to now. Complementary, non-opioid therapies are sought for both prevention and management of CIPN.

We support our perspective by evaluating sensorimotor effects of chemotherapy, the metrics to assess sensorimotor deficits, and relevant clinical studies. We subsequently analyse the neurological substrate of VR sensorimotor rehabilitation, with multisensory integration acting as a key element. Finally, we propose a closed-loop patient-centered design recommendation for CIPN sensorimotor rehabilitation. Our aim is to provoke the scientific community toward the development and use of such digital interventions for more efficient and targeted rehabilitation.}, language = {en} } @article{KondylakisAxenieBastolaetal.2020, author = {Kondylakis, Haridimos and Axenie, Cristian and Bastola, Dhundy and Katehakis, Dimitrios G. and Kouroubali, Angelina and Kurz, Daria and Larburu, Nekane and Mac{\´i}a, Iv{\´a}n and Maguire, Roma and Maramis, Christos and Marias, Kostas and Morrow, Philip and Muro, Naiara and N{\´u}{\~n}ez-Benjumea, Francisco Jos{\´e} and Rampun, Andrik and Rivera-Romero, Octavio and Scotney, Bryan and Signorelli, Gabriel and Wang, Hui and Tsiknakis, Manolis and Zwiggelaar, Reyer}, title = {Status and Recommendations of Technological and Data-Driven Innovations in Cancer Care: Focus Group Study}, volume = {22}, pages = {e22034}, journal = {Journal of Medical Internet Research}, number = {12}, publisher = {JMIR Publications}, address = {Toronto}, issn = {1438-8871}, doi = {https://doi.org/10.2196/22034}, year = {2020}, abstract = {Background: The status of the data-driven management of cancer care as well as the challenges, opportunities, and recommendations aimed at accelerating the rate of progress in this field are topics of great interest. Two international workshops, one conducted in June 2019 in Cordoba, Spain, and one in October 2019 in Athens, Greece, were organized by four Horizon 2020 (H2020) European Union (EU)-funded projects: BOUNCE, CATCH ITN, DESIREE, and MyPal. The issues covered included patient engagement, knowledge and data-driven decision support systems, patient journey, rehabilitation, personalized diagnosis, trust, assessment of guidelines, and interoperability of information and communication technology (ICT) platforms. A series of recommendations was provided as the complex landscape of data-driven technical innovation in cancer care was portrayed. Objective: This study aims to provide information on the current state of the art of technology and data-driven innovations for the management of cancer care through the work of four EU H2020-funded projects. Methods: Two international workshops on ICT in the management of cancer care were held, and several topics were identified through discussion among the participants. A focus group was formulated after the second workshop, in which the status of technological and data-driven cancer management as well as the challenges, opportunities, and recommendations in this area were collected and analyzed. Results: Technical and data-driven innovations provide promising tools for the management of cancer care. However, several challenges must be successfully addressed, such as patient engagement, interoperability of ICT-based systems, knowledge management, and trust. This paper analyzes these challenges, which can be opportunities for further research and practical implementation and can provide practical recommendations for future work. Conclusions: Technology and data-driven innovations are becoming an integral part of cancer care management. In this process, specific challenges need to be addressed, such as increasing trust and engaging the whole stakeholder ecosystem, to fully benefit from these innovations.}, language = {en} } @article{MathiasSchmiedGrossmann2020, author = {Mathias, Selvine George and Schmied, Sebastian and Großmann, Daniel}, title = {A framework for monitoring multiple databases in industries using OPC UA}, volume = {12}, journal = {Journal of Ambient Intelligence and Humanized Computing}, number = {1}, publisher = {Springer}, address = {Berlin}, issn = {1868-5145}, doi = {https://doi.org/10.1007/s12652-020-02850-x}, pages = {47 -- 56}, year = {2020}, abstract = {Database management and monitoring is an inseparable part of any industry.

Probiotic treatment also resulted in a decreased number of patients with VSE and ESBL. While decreased incidence of VRE occurred immediately, decreased VSE and ESBL numbers occurred months later. A probiotic-mediated decrease of VSE and ESBL incidence cannot be explained when assuming bacterial transmission exclusively as a linear cause and effect event. The decrease is better understood by considering bacterial transmissions to be stochastic events, which depend on various driving forces similar to an electric current. We hypothesize that VRE, VSE and ESBL uptake by patients and by staff members mutually reinforced each other, leading staff members to form a bacterial reservoir, similar to a condenser that stores electrical energy.

This knowledge is particularly relevant when the therapeutic agents are remarkably adaptable and diverse biological entities capable of a plethora of interactions, most of which remain largely unexplored. Although phage therapy (PT) undoubtedly holds the potential to save lives, its current efficacy in case studies recalls the golden era of antibiotics, when these compounds were highly effective and the possibility of them becoming ineffective seemed remote. Safe PT schemes depend on our understanding of how phages interact with, and evolve in, highly complex environments. Here, we summarize and review emerging evidence in a commonly overlooked theme in PT: bacteria-phage interactions. In particular, we discuss the influence of quorum sensing (QS) on phage susceptibility, the consequent role of phages in modulating bacterial cooperation, and the potential implications of this relationship in PT, including how we can use this knowledge to inform PT strategies. We highlight that the influence of QS on phage susceptibility seems to be widespread but can have contrasting outcomes depending on the bacterial host, underscoring the need to thoroughly characterize this link in various bacterial models. Furthermore, we encourage researchers to exploit competition experiments, experimental evolution, and mathematical modeling to explore this relationship further in relevant infection models. Finally, we emphasize that long-term PT success requires research on phage ecology and evolution to inform the design of optimal therapeutic schemes.}, language = {en} } @article{HechelmannSeeversOtteetal.2020, author = {Hechelmann, Ron-Hendrik and Seevers, Jan-Peter and Otte, Alexander and Sponer, Jan and Stark, Matthias}, title = {Renewable Energy Integration for Steam Supply of Industrial Processes: A Food Processing Case Study}, volume = {13}, pages = {2532}, journal = {Energies}, number = {10}, publisher = {MDPI}, address = {Basel}, issn = {1996-1073}, doi = {https://doi.org/10.3390/en13102532}, year = {2020}, abstract = {This study highlights the CO2,e -emission reduction potentials and related economic consequences for changing steam generation from fossil to renewable.

A cylindrical tank of 1400 m3 was considered. For the model-based optimisation, the substrate was considered as a non-Newtonian fluid with a density of 1090 kg/m3. The Oswald-de Waele power-law model was selected to account for the rheological behaviour of the fluid. Installation parameters of the mixers were rotational angles and heights of the shafts of the two propellers. A computational model was developed to simulate the fluid dynamics depending on the mixing process inside the tank. Several configurations were analysed according to evaluating criteria such as the value of the fluid velocity, its distribution along the three spatial dimensions, and the power consumption to rotate the mixers. The maximum fluid velocity and minimum power consumption were observed when the propellers are located at intermediate height inside the tank and with the shafts perpendicular to the tank radius. With this configuration, the fluid reaches a maximum velocity of 0.28 m/s.

In this work, we have developed novel single and matrix capacitive tactile sensors to measure the occupant's contact data. They can be integrated with the airbag surface and folded to follow the dynamic airbag shape during the deployment. The sensors are tested under a low-velocity pendulum impact and benchmarked with high-speed test videos. The results reveal that the single sensor can successfully measure occupant-airbag contact time and estimate the area, while the contact position is additionally identified from the matrix sensor.}, language = {en} } @article{SchussWintersbergerRiener2021, author = {Schuß, Martina and Wintersberger, Philipp and Riener, Andreas}, title = {Security Issues in Shared Automated Mobility Systems: A Feminist HCI Perspective}, volume = {5}, pages = {43}, journal = {Multimodal Technologies and Interaction}, number = {8}, publisher = {MDPI}, address = {Basel}, issn = {2414-4088}, doi = {https://doi.org/10.3390/mti5080043}, year = {2021}, abstract = {The spread of automated vehicles (AVs) is expected to disrupt our mobility behavior.

Languages that can provide memory safety at compile-time can be used instead. This thesis examines the suitability of the Rust programming language for embedded software development. The relatively new language provides such memory safety guarantees while offering high performance comparable to other common languages. The objectives of the thesis are to assess the suitability of Rust in comparison to an existing language and to explain the necessary steps when eventually switching development to Rust. The C language is used for the comparison, as it is currently the most common language for embedded software development. To be able to assess Rust objectively, the comparison to C is carried out on the basis of pre-defined aspects that were deemed important. This comparison is explained and discussed in the main part of the thesis. Furthermore, this part contrasts safety and performance by explaining the different safety problems as well as countermeasures and subsequently comparing an example program according to the performance in both languages. To be able to examine the switching process, another set of criteria is employed. Rust is analyzed according to them and an exemplary switching process is provided. Comparing the criteria leads to different findings. Some aspects show a similar suitability of Rust and C. These include the popularity, the compliance with safety standards as well as the performance, although the latter highly depends on the tested application. Positive aspects of C include the large amount of available compilation targets and the maturity. Rust on the other hand stands out through a greater variety of programming paradigms, a state-of-the-art and well-adopted toolchain as well as good documentation, community support and a sound ecosystem. Furthermore the safety guarantees pose a clear advantage over C and make embedded software provably safer. It is also shown that for switching to Rust, numerous resources for employee training are available and different tools for the integration into an existing code base are offered by the programming language and its ecosystem. The results suggest that Rust is indeed suitable for embedded software development, although the choice must not be made without careful consideration of the examined criteria.}, language = {en} } @thesis{Binder2020, author = {Binder, Kathrin Susanne}, title = {Autobahn fahren in geteilter Kontrolle}, subtitle = {Entwicklung eines HMI-Designs zur Steigerung der User Experience und Akzeptanz der Fahrenden w{\"a}hrend einem bedingt automatisierten Fahrbetrieb}, publisher = {Technische Hochschule Ingolstadt}, address = {Ingolstadt}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:573-7845}, pages = {62, XXVIII}, school = {Technische Hochschule Ingolstadt}, year = {2020}, language = {de} } @thesis{AsadollahiEsfahani2021, author = {Asadollahi Esfahani, Bahareh}, title = {Integrating renewable energies into a district heating network in a residential area in Dachau}, publisher = {Technische Hochschule Ingolstadt}, address = {Ingolstadt}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:573-7764}, pages = {XIV, 92}, school = {Technische Hochschule Ingolstadt}, year = {2021}, abstract = {The project includes designing a low-temperature district heating network center with a flow and return temperature of 45 °C/20 °C in a modern residential area with 50 buildings with 37,000 square meters located in Dachau, Bavaria and consists two scenarios.

This downside causes the necessity to use data science techniques to automate the analysis of an ensemble of crash simulation data. This study aims at setting up a workflow to dimensionally reduce the simulation data, cluster it based on a behavioral pattern and analyze a particular behavioral pattern to obtain if-else rules to avoid or achieve that particular behavioral pattern. In this context, a behavioral pattern refers to an observed characteristic result that occurs because of specific input parameter values. In this thesis, dimensionality reduction is undertaken using feature extraction algorithms, the knowledge behind the simulations is extracted and clustered based on an individual simulation's behavioral pattern using unsupervised clustering algorithms, and the rules to avoid or achieve a particular behavioral pattern are extracted using decision tree algorithm and associative rule mining algorithm. The workflow is applied to a simple side pole impact test, where a pole is impacted to an assembly of three parallel vertical members welded to a horizontal member. Using the workflow, every simulation data is represented using 50 lower-dimensional parameters and the simulations in the dataset are clustered into three different clusters based on three different behavioral patterns observed. One of the behavioral patterns observed is lower buckling of a vertical member, which is not a desired crash behavior to be observed in a crash energy absorption structure and this behavior should be avoided. The rules to avoid this behavioral pattern is further obtained using rule extraction. The results from the study suggest that the workflow and the algorithms used in this thesis to analyze an ensemble of simulation data helps an engineer in efficiently representing simulation data using lower-dimensional embedding, extracting the underlying knowledge, and obtaining rules to avoid or achieve a certain behavioral pattern. Furthermore, there are many interesting directions worth perusing based on this thesis, (1) Achieving generalizability while using simulations of different mesh criteria.

Simultan zu der Definition der Anforderungen und der Entwicklung der Sprach-Elemente wurde der Trans-Compiler implementiert. Mit mehreren, abstrakten Testf{\"a}llen wurden die Sprach-Elemente der DSL untersucht, um zu pr{\"u}fen, ob der Trans-Compiler aus g{\"u}ltigem DSL-Code validen C-Code generiert. Schrittweise wurden alle Testf{\"a}lle validiert, sodass schlussendlich sichergestellt werden konnte, dass der Compiler aus syntaktisch und semantisch korrektem DSL-Code stets g{\"u}ltigen C-Code generiert. Das Ziel, eine dom{\"a}nenspezifische Sprache zu entwickeln, die eine getrennte Entwicklung und Integration von Algorithmen erlaubt, wurde erreicht. Mehrere CSV-Dateien erm{\"o}glichen die unabh{\"a}ngige Integration verschiedener Algorithmen in gr{\"o}ßere Projekte.}, language = {de} } @thesis{Geltermair2021, author = {Geltermair, Jonas}, title = {Entwicklung eines spielfreien Planetengetriebes f{\"u}r die Erprobung}, publisher = {Technische Hochschule Ingolstadt}, address = {Ingolstadt}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:573-8007}, pages = {38, LXXIII}, school = {Technische Hochschule Ingolstadt}, year = {2021}, abstract = {Das Ziel dieser Bachelorarbeit ist die fertigungsgerechte Konstruktion und Entwicklung eines Planetengetriebeaufbaus auf Basis des spielfreien Stirnradsystems der Firma WMH Herion GmbH. Dabei werden zwei verschiedene Versionen angefertigt. Eine Variante des Getriebeaufbaus zielt auf die Demonstration des Getriebeaufbaus ab und soll den Mechanismus des Verspannens des Getriebes aufzeigen, um Interessierten die M{\"o}glichkeit zu geben, die Funktionsweise des Getriebes zu verstehen. Die zweite Aufbauvariante ist torsionssteifer und somit f{\"u}r Versuche auf dem Getriebepr{\"u}fstand ausgelegt, um die Tragf{\"a}higkeit unter wirkendem Drehmoment zu ermitteln. Dabei werden die strukturellen Festigkeiten einzelner Bauteile mit Hilfe von analytischen Berechnungen und FEM-Simulationen nachgewiesen.}, language = {de} } @thesis{Geins2020, author = {Geins, Stephan Christoph}, title = {Bewertung des weltweiten Marktpotenzials f{\"u}r elektrisch betriebene F{\"a}hren im innerst{\"a}dtischen Verkehr}, publisher = {Technische Hochschule Ingolstadt}, address = {Ingolstadt}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:573-7998}, pages = {XII, 86}, school = {Technische Hochschule Ingolstadt}, year = {2020}, language = {de} }
