The multilingual dictionary of noun valency Portlex is considered to be the trigger for the creation of the automatic language generators Xera and Combinatoria, whose development and use is presented in this paper. Both prototypes are used for the automatic generation of nominal phrases with their mono- and bi-argumental valence slots, which could be used, among others, as dictionary examples or as integrated components of future autonomous E-Learning-Tools. As samples for new types of automatic valency dictionaries including user interaction, we consider the language generators as we know them today. In the specific methodological procedure for the development of the language generators, the syntactic-semantic description of the noun slots turns out to be the main focus from a syntagmatic and paradigmatic point of view. Along with factors such as representativeness, grammatical correctness, semantic coherence, frequency and the variety of lexical candidates, as well as semantic classes and argument structures, which are fixed components of both resources, a concept of a multi-sided prototype stands out. The combined application of this prototype concept as well as of word embeddings together with techniques from the field of automatic natural language processing and generation (NLP and NLG) opens up a new way for the future development of automatically generated plurilingual valency dictionaries. All things considered, the paper depicts the language generators both from the point of view of their development as well as from that of the users. The focus lies on the role of the prototype concept within the development of the resources., Comment: 31 pages, in German language

The safety of streets is difficult to quantify numerically. However, it is possible to sort streets regarding their safety into ordered categories, like safe, neutral and unsafe. In this paper we model the computation of safe bicycle routes as an optimization problem with ordinal coefficients. We describe an appropriate optimality concept for ordinal optimization problems and introduce a solution strategy for ordinal routing problems. Furthermore, we introduce a concept to incorporate safety preferences by introducing weights such that longer path with a higher safety rating are preferred. We apply the concept of ordinal routing to compute safe bicycle routes in Stuttgart, Germany, based on dates from OpenStreetMaps. We show that the choice of the weights does not only represent the trade-off of safety vs. path length, but has also an impact on the number of alternative solutions and thus on the computation time. -- Die Sicherheit von Wegen ist nur eingeschr\"ankt messbar und daher schwierig zu quantifizieren. Dahingegen ist es verh\"altnism\"a{\ss}ig leicht Wege bez\"uglich ihrer Sicherheit in geordnete Kategorien, wie beispielsweise sicher, neutral und gef\"ahrlich einzuordnen. In diesem Beitrag werden Optimierungsprobleme mit geordneten Kategorien formuliert und Optimalit\"at f\"ur diese definiert. Daraus wird eine L\"osungsstrategie f\"ur solche Probleme abgeleitet. Dar\"uber hinaus wird erkl\"art, wie die Abgrenzung zwischen den Kategorien erh\"oht werden kann, sodass l\"angere aber daf\"ur sicherere Wege mit Hilfe von Gewichten berechnet werden k\"onnen. Diese theoretischen Ergebnisse werden in der Praxis angewendet und es werden auf Grundlage von Daten von OpenStreetMaps sichere Fahrradwege in Stuttgart berechnet. Dabei zeigt sich, dass eine gute Wahl der Gewichte zu weniger L\"osungen und k\"urzeren Rechenzeiten f\"uhrt., Comment: 13 pages in German

This paper addresses the central question of what a coherent concept of probability might look like that would do justice to both classical probability theory, axiomatized by Kolmogorov, and quantum theory. At a time when quanta are receiving increased and expanded attention -- think, for example, of the advances in quantum computers or the promises associated with this new technology (National Academies of Sciences: Engineering, and Medicine, 2019) -- an adequate interpretation of probability, which is no less important, should be given due attention, particularly with regard to quantum theory., Comment: in German language

Record linkage means linking data from multiple sources. This approach enables the answering of scientific questions that cannot be addressed using single data sources due to limited variables. The potential of linked data for health research is enormous, as it can enhance prevention, treatment, and population health policies. Due the sensitivity of health data, there are strict legal requirements to prevent potential misuse. However, these requirements also limit the use of health data for research, thereby hindering innovations in prevention and care. Also, comprehensive Record linkage in Germany is often challenging due to lacking unique personal identifiers or interoperable solutions. Rather, the need to protect data is often weighed against the importance of research aiming at healthcare enhancements: for instance, data protection officers may demand the informed consent of individual study participants for data linkage, even when this is not mandatory. Furthermore, legal frameworks may be interpreted differently on varying occasions. Given both, technical and legal challenges, record linkage for health research in Germany falls behind the standards of other European countries. To ensure successful record linkage, case-specific solutions must be developed, tested, and modified as necessary before implementation. This paper discusses limitations and possibilities of various data linkage approaches tailored to different use cases in compliance with the European General Data Protection Regulation. It further describes requirements for achieving a more research-friendly approach to linking health data records in Germany. Additionally, it provides recommendations to legislators. The objective of this work is to improve record linkage for health research in Germany., Comment: in German language

In this working paper, we turn our attention to two exemplary, cross-media shitstorms directed against well-known individuals from the business world. Both have in common, first, the trigger, a controversial statement by the person who thereby becomes the target of the shitstorm, and second, the identity of this target as relatively privileged: cis-male, white, successful. We examine the spread of the outrage wave across two media at a time and test the applicability of computational linguistic methods for analyzing its time course. Assuming that harmful language spreads like a virus in digital space, we are primarily interested in the events and constellations that lead to the use of harmful language, and whether and how a linguistic formation of "tribes" occurs. Our research therefore focuses, first, on the distribution of linguistic features within the overall shitstorm: are individual words or phrases increasingly used after their introduction, and through which pathways they spread. Second, we ask whether "tribes," for example, one group of supporters and one of opponents of the target, have a distinguished linguistic form. Our hypothesis is that supporters remain equally active over time, while the dynamic "ripple" effect of the shitstorm is based on the varying participation of opponents., Comment: in German language

In this paper, we investigate the computational complexity of solutions to the Laplace and the diffusion equation. We show that for a certain class of initial-boundary value problems of the Laplace and the diffusion equation, the solution operator is $\# P_1/ \#P$-complete in the sense that it maps polynomial-time computable functions to the set of $\#P_1/ \#P$-complete functions. Consequently, there exists polynomial-time (Turing) computable input data such that the solution is not polynomial-time computable, unless $FP=\#P$ or $FP_1=\#P_1$. In this case, we can, in general, not simulate the solution of the Laplace or the diffusion equation on a digital computer without having a complexity blowup, i.e., the computation time for obtaining an approximation of the solution with up to a finite number of significant digits grows non-polynomially in the number of digits. This indicates that the computational complexity of the solution operator that models a physical phenomena is intrinsically high, independent of the numerical algorithm that is used to approximate a solution., Comment: The results of this paper on simulating physical theories on digital computers influenced the article of Holger Boche und Frank Fitzek "Metaverse at the campfire of the future" in Germany's major newspaper, the Frankfurter Allgemeine Zeitung (FAZ) (URL: https://www.faz.net/-ikh-aqw8x).

Nowadays, Machine Learning (ML) is experiencing tremendous popularity that has never been seen before. The operationalization of ML models is governed by a set of concepts and methods referred to as Machine Learning Operations (MLOps). Nevertheless, researchers, as well as professionals, often focus more on the automation aspect and neglect the continuous deployment and monitoring aspects of MLOps. As a result, there is a lack of continuous learning through the flow of feedback from production to development, causing unexpected model deterioration over time due to concept drifts, particularly when dealing with scarce data. This work explores the complete application of MLOps in the context of scarce data analysis. The paper proposes a new holistic approach to enhance biomedical image analysis. Our method includes: a fingerprinting process that enables selecting the best models, datasets, and model development strategy relative to the image analysis task at hand; an automated model development stage; and a continuous deployment and monitoring process to ensure continuous learning. For preliminary results, we perform a proof of concept for fingerprinting in microscopic image datasets., Comment: 21 pages, 5 figures , 33. Workshop on Computational Intelligence Berlin Germany

It is known that there exist mathematical problems of practical relevance which cannot be computed on a Turing machine. An important example is the calculation of the first derivative of continuously differentiable functions. This paper precisely classifies the non-computability of the first derivative, and of the maximum-norm of the first derivative in the Zheng-Weihrauch hierarchy. Based on this classification, the paper investigates whether it is possible that a Turing machine detects this non-computability of the first derivative by observing the data of the problem, and whether it is possible to detect upper bounds for the peak value of the first derivative of continuously differentiable functions. So from a practical point of view, the question is whether it is possible to implement an exit-flag functionality for observing non-computability of the first derivative. This paper even studies two different types of exit-flag functionality. A strong one, where the Turing machine always has to stop, and a weak one, where the Turing machine stops if and only if the input lies within the corresponding set of interest. It will be shown that non-computability of the first derivative is not detectable by a Turing machine for two concrete examples, namely for the problem of computing the input--output behavior of simple analog circuits and for solutions of the three-dimensional wave equation. In addition, it is shown that it is even impossible to detect an upper bound for the maximum norm of the first derivative. In particular, it is shown that all three problems are not even semidecidable. Finally, we briefly discuss implications of these results for analog and quantum computing., Comment: To appear in IEEE Trans. Inf. Theory. This paper influenced the article of F. Fitzek and H. Boche "Metaverse at the campfire of the future" in Germany's major newspaper, the Frankfurter Allgemeine Zeitung (FAZ), https://www.faz.net/aktuell/wirtschaft/digitec/metaverse-am-lagerfeuer-der-zukunft-18051009.html.

The complexity and increasingly tight coupling of supply chains poses a major logistical challenge for leading companies. Another challenge is that leading companies -- under pressure from consumers, a critical public and legislative measures such as supply chain laws -- have to take more responsibility than before for their suppliers' labour standards. In this paper, we discuss a new approach that leading companies are using to try to address these challenges: algorithmic prediction of business risks, but also environmental and social risks. We describe the technical and cultural conditions for algorithmic prediction and explain how -- from the perspective of leading companies -- it helps to address both challenges. We then develop scenarios on how and with what kind of social consequences algorithmic prediction can be used by leading companies. From the scenarios, we derive policy options for different stakeholder groups to help develop algorithmic prediction towards improving labour standards and worker voice. -- Die Komplexit\"at und zunehmend enge Kopplung vieler Lieferketten stellt eine gro{\ss}e logistische Herausforderung f\"ur Leitunternehmen dar.

If you want to fill $n \in \mathbb{N}$ seats in succession with $n$ people and the rule that each person chooses one of the seats with the maximum distance to an occupied seat, then you can ask yourself how many possibilities there are for this. In this paper, based on initially mentioned ideas, a formula for the number of these possibilities will be found. In addition, a lower and upper bound for this formula will be given. Finally, formulas for the OEIS sequences A166079, A095236, A095240 and A095912 and an extension of the initial problem are derived., Comment: 21 pages, in German language, 3 figures

Theoretical background: early verbal development is not yet fully understood, especially in its formative phase. Research question: can a reliable, easy-to-use coding scheme for the classification of early infant vocalizations be defined that is applicable as a basis for further analysis of language development? Methods: in a longitudinal study of 45 neurotypical infants, we analyzed vocalizations of the first 4 months of life. Audio segments were assigned to 5 classes: (1) Voiced and (2) Voiceless vocalizations; (3) Defined signal; (4) Non-target; (5) Nonassignable. Results: Two female coders with different experience achieved high agreement without intensive training. Discussion and Conclusion: The reliable scheme can be used in research and clinical settings for efficient coding of infant vocalizations, as a basis for detailed manual and machine analyses., Comment: This paper is in German

Developers have to obtain a sound understanding of existing risk potentials already in the concept phase of driverless vehicles. Deductive as well as inductive SOTIF analyses of potential triggering conditions for hazardous behavior help to achieve this goal. In this regard, ISO 21448 suggests conducting a System-Theoretic Process Analysis (STPA). In this article, we introduce German terminology for SOTIF considerations and critically discuss STPA theory in the course of an example application, while also proposing methodological additions. -- -- Um bereits in der Konzeptphase autonomer Fahrzeuge einen fundierten Eindruck bestehender Risikopotenziale zu erhalten, werden im Zuge von deduktiven und induktiven SOTIF-Analysen m\"ogliche ausl\"osende Umst\"ande f\"ur gef\"ahrliches Verhalten untersucht.

Roughly spoken, Functionalanalysis means the study of the category of infinite-dimensional vectorspaces over the field of real or complex numbers, together with their linear maps. In most cases, one further needs a topological structure on such a vectorspace, because then, you can consider the continuous linear maps between such spaces. The name Functionalanalysis is due to the fact, that in the beginning of the theory, the authors wanted to expand Calculus onto functionals of spaces of functions. Functionalanalytical results give the possibility to solve problems in the Theory of (Partial) Differential Equations, in Complex Analysis or in Quantum Mechanics. But the aim of this lines is not to explain the applications. We will discuss the mathematical theory of almost metric spaces, normed vector spaces and algebras, spaces of continuous resp. $p$-integrable functions as well as reflexive and uniformly convex spaces. ad v2: We added that, in the case $p \in {]}0,1{[}$, $L^p$ is the completion of the compactly supported continuous functions (with the obvious metric), too. Actually, the proof is the same as in the case $p \in {[}1, \infty{[}$., Comment: 288 pp, in German

In a social networked industry, the focus is on collaboration between humans and technology. Communication is the basic prerequisite for synergetic collaboration between all players. It includes non-verbal as well as verbal interactions. To enable non-verbal interaction, machines must be able to detect and understand human movements. This article presents the ongoing fundamental research on the analysis of human movements using sensor-based activity recognition and identifies potential for a transfer to industrial applications. The focus is on the practical feasibility of activity recognition by adding further data streams such as the position data of logistical objects and tools, meaning the context in which a certain activity is carried out. -- In der Social Networked Industry steht die Zusammenarbeit von Mensch und Technik im Vordergrund.

Quantum physics is a long established content in high school curricula. More recently, alternative approaches based on information-theoretical formulations of quantum theory have been discussed, in which conceptual emphases change in comparison to established didactical approaches. In particular, the notions of "superposition" and "entanglement" are brought into the center of discussion in these approaches. Likewise, there is a broad public interest in the new applications of quantum physics such as quantum computing, which has led to a variety of popular depictions. In this paper we identify common inaccuracies and errors in these representations, explain the technical background and make first recommendations to avoid misunderstandings. Our initial focus is on the notion of "superposition". -- Die Quantenphysik ist seit vielen Jahren ein etablierter Inhalt der Oberstufenphysik.

Sensor and control data of modern mechatronic systems are often available as heterogeneous time series with different sampling rates and value ranges. Suitable classification and regression methods from the field of supervised machine learning already exist for predictive tasks, for example in the context of condition monitoring, but their performance scales strongly with the number of labeled training data. Their provision is often associated with high effort in the form of person-hours or additional sensors. In this paper, we present a method for unsupervised feature extraction using autoencoder networks that specifically addresses the heterogeneous nature of the database and reduces the amount of labeled training data required compared to existing methods. Three public datasets of mechatronic systems from different application domains are used to validate the results., Comment: A later version of this paper in German language was submitted to VDI Mechatronic Tagung 2021 and will be published in the conference proceedings

This paper presents the development of a real-time simulator for the validation of controlling a large vehicle manipulator. The need for this development can be justified by the lack of such a simulator: There are neither open source projects nor commercial products, which would be suitable for testing cooperative control concepts. First, we present the nonlinear simulation model of the vehicle and the manipulator. For the modeling MATLAB/Simulink is used, which also enables a code generation into standalone C++ ROS-Nodes (Robot Operating System Nodes). The emerging challenges of the code generation are also discussed. Then, the obtained standalone C++ ROS-Nodes integrated in the simulator framework which includes a graphical user interface, a steering wheel and a joystick. This simulator can provide the real-time calculation of the overall system's motion enabling the interaction of human and automation. Furthermore, a qualitative validation of the model is given. Finally, the functionalities of the simulator is demonstrated in tests with a human operators., Comment: in German language

With the increasing attention non-binary people receive in Western societies, strategies of gender-fair language have started to move away from binary (only female/male) concepts of gender. Nevertheless, hardly any approaches to take these identities into account into machine translation models exist so far. A lack of understanding of the socio-technical implications of such technologies risks further reproducing linguistic mechanisms of oppression and mislabelling. In this paper, we describe the methods and results of a workshop on gender-fair language and language technologies, which was led and organised by ten researchers from TU Wien, St. P\"olten UAS, FH Campus Wien and the University of Vienna and took place in Vienna in autumn 2021. A wide range of interest groups and their representatives were invited to ensure that the topic could be dealt with holistically. Accordingly, we aimed to include translators, machine translation experts and non-binary individuals (as "community experts") on an equal footing. Our analysis shows that gender in machine translation requires a high degree of context sensitivity, that developers of such technologies need to position themselves cautiously in a process still under social negotiation, and that flexible approaches seem most adequate at present. We then illustrate steps that follow from our results for the field of gender-fair language technologies so that technological developments can adequately line up with social advancements. ---- Mit zunehmender gesamtgesellschaftlicher Wahrnehmung nicht-bin\"arer Personen haben sich in den letzten Jahren auch Konzepte von genderfairer Sprache von der bisher verwendeten Binarit\"at (weiblich/m\"annlich) entfernt.

With the increasing use of big data and business analytics, data storytelling has gained popularity as an effective means of communicating analytical insights to audiences to support decision making and improve business performance. However, there is little empirical evidence on the impact of data storytelling on data understanding. This study validates the concept of data storytelling as a construct in terms of its impact on users' data understanding. Based on empirical data analysis, the results of this study show that data storytelling competence is positively associated with organizational performance, which is partly due to the quality of the decision is conveyed. These results provide a theoretical basis for further investigation of potential antecedents and consequences of data storytelling., Comment: in German language

The present work is the author's doctoral thesis, written during his studies at the University of Bonn. Its goal is to establish the foundations of $K$-theory in the context of adic geometry using the formalism of condensed mathematics and Efimov's results on localizing invariants of dualizable categories. In particular, we study the descent properties of our version of $K$-theory and prove that it satisfies Nisnevich descent on analytic adic spaces. Furthermore, we show that $K$-theory forms a sheaf with respect to the \'etale topology after chromatic localization. Finally, we use this result to prove an analog of the Grothendieck-Riemann-Roch theorem for analytic adic spaces., Comment: in German

We observe that many of the 2-complexes constructed by Freedman-Krushkal-Teichner in their paper on the incompleteness of the van Kampen embedding obstruction can actually be PL immersed in $\mathbb{R}^4$ in such a way that the images of the interiors of distinct cells are disjoint. In other words, they PL almost-embed in $\mathbb{R}^4$ with singularities occurring only as self intersections of some 2-cells.

Fluctuations are ubiquitous in nature. They are one of the fundamental building blocks of quantum mechanics and are responsible for a wide variety of phenomena in many areas of physics, ranging from biology to cosmology. Far from any classical intuition, quantum fluctuations are for instance responsible for the appearance of forces between non-magnetic and electrically neutral objects in vacuum, which seem to arise out of nothing. Ever since, quantum fluctuations have fascinated basic research providing new insights into physics and their understanding is becoming increasingly important for various future technologies. -- Fluktuationen sind allgegenw\"{a}rtig.

The thesis 'Investigations to Improve Energy Resolution for Neutron Backscattering Spectrometers Using Ideal Crystals with Low Dynamic Width of the Reflection Curve' first introduces the concept of the neutron backscattering spectrometer and their scanning methods by Doppler variation of the neutron energy on a moving Bragg-reflecting crystal. It further reveals the foundations of the dynamical theory of diffraction, with concepts on dispersion surfaces describing total reflection, refraction, and Laue-Bragg diffraction. The natural line width of a reflecting crystal is given by the structure factor, which limits the energy resolution of a Si-111 monochromator to a minimal 300 neV. The present project is to investigate the energy resolution of the GaAs-200 reflection, theoretically limited to 13 neV. An experimental setup is presented encompassing optics, mechanics, and detector electronics, and an experimental line width of 43 neV has been obtained. The value is discussed with error sources such as temperature stability, vibrations, misalignment, and crystal defects., Comment: PhD thesis (1990). in German language.

The collective risk model differentiates usually between claims frequencies (and their distribution) and claim sizes (and their distribution). For the claims frequencies typically classical discrete distributions are considered, such as Binomial-, Negative binomial- or Poisson distributions. Since these distributions sometimes do not really fit to the data we propose a different approach here for claim frequencies via random proportions of the number of insurance contracts. This approach also allows for a statistical goodness-of-fit test via quantile-quantile-plots and can likewise be applied to the modelling of claim size distributions., Comment: in German language, 8 pages, 9 figures

Creating anonymity means cutting connections. A common goal in this context is to prevent accountability. This prevention of accountability can be problematic, for example, if it leads to delinquents remaining undetected. However, imputability can also provide protection against discrimination. In medical, religious or legal matters, this is of fundamental importance. Thus, when individuals actively establish anonymity, they do so mostly because they want to prevent certain information about them, that is, sensitive and/or compromising information, from being associated with their identities. By remaining inaccessible as individuals with respect to certain information about them, they can engage in forms of exchange that would otherwise be impossible for them. Examples include practices of exchange in (self-organized) therapy groups, acting out stigmatized sexual preferences, the role of anonymity in the performing arts, or political resistance movements. Given the variety of examples in which personal anonymity is important, it is not surprising that it is primarily these personal dimensions that are the focus of current debates about the increasing precariousness of anonymity in the face of new technical possibilities of data mining and processing. In this paper, we nevertheless - or precisely because of this - want to focus on another aspect of anonymity that has received much less attention so far. Namely, we assume that researching and working with and about anonymity can open up new perspectives on and for contemporary forms of knowledge production., Comment: 4 pages, in German, journal article, Helm, P. 2021.

This paper addresses the question of how and with what consequences anonymity is used as a creative element in experiments dealing with alternative forms of knowledge production. More specifically, the focus is on a particular current in contemporary dance, experimental dance. This has developed in the course of the 1970s. Its guiding idea is to shift the focus away from finished choreography and performance to the processuality, spontaneity, and experience of dance practice itself. Dance is seen as a laboratory in which to experiment with gravity, body boundaries, group dynamics and perception. The focus is on testing, touching, trying. The corresponding events are called either 'Dance Labs' or 'Movement Research Workshops', depending on the regularity. An instrument that is often used in the context of such events to create specific social situations and group dynamics or to channel perceptions in certain directions is anonymity. Anonymity is broadly understood as the capping of connections that results in a degree of unaccountability with respect to various aspects of a person, situation, or activity. For example, unaccountability can arise from the fact that people can no longer see each other, so that visual identification becomes impossible, even if only temporarily. By breaking familiar modes of identification, other forms of relating can sometimes be emphasized. This is what makes this form of anonymity so interesting for experimental dance., Comment: Journal Article, 5 pages, in German, 3 figures

The more AI-assisted decisions affect people's lives, the more important the fairness of such decisions becomes. In this chapter, we provide an introduction to research on fairness in machine learning. We explain the main fairness definitions and strategies for achieving fairness using concrete examples and place fairness research in the European context. Our contribution is aimed at an interdisciplinary audience and therefore avoids mathematical formulation but emphasizes visualizations and examples. -- Je mehr KI-gest\"utzte Entscheidungen das Leben von Menschen betreffen, desto wichtiger ist die Fairness solcher Entscheidungen. In diesem Kapitel geben wir eine Einf\"uhrung in die Forschung zu Fairness im maschinellen Lernen. Wir erkl\"aren die wesentlichen Fairness-Definitionen und Strategien zur Erreichung von Fairness anhand konkreter Beispiele und ordnen die Fairness-Forschung in den europ\"aischen Kontext ein. Unser Beitrag richtet sich dabei an ein interdisziplin\"ares Publikum und verzichtet daher auf die mathematische Formulierung sondern betont Visualisierungen und Beispiele., Comment: in German language

Let $k\in\mathbb{N}_0\cup\{\infty\}$. According to Whitney's extension theorem, each real-valued Whitney $k$-Jet on a closed subset $A\subseteq\mathbb{R}^n$ can be extended to a $C^k$-function on $\mathbb{R}^n$. Based on Whitney's original work, we prove analogous results for jets and functions with values in a real Hausdorff locally convex topological vector space $E$. In the case $k<\infty$, we obtain a continious linear extension operator, that is a continious linear right inverse of the map $C^k(\mathbb{R}^n,E)\to \mathcal{E}^k(A,E),\ f\mapsto ((\partial^{\alpha} f)\vert_A)_{\vert\alpha\vert\leq k}.$ Assuming that $E$ ist metrizable, we also succeed in extending Whitney $\infty$-jets. Given a $C^k$-manifold $M$ (which may have a "rough boundary"), we deal with the problem how to extend Whitney $k$-Jets defined on closed subsets $A\subseteq M$ to $C^k$-functions on $M$. In particular, we show for $k<\infty$ that the restriction map $C^k(M,E)\to C^k(A,E),\ f\mapsto f\vert_A$ has a continuous linear right inverse for each closed submanifold $A\subseteq M$ if $M$ is $C^k$-paracompact and $A$ locally compact, or if $M$ is regular and $A$ compact. ----- Sei $k\in\mathbb{N}_0\cup\{\infty\}$. Der Whitneysche Fortsetzungssatz besagt, dass sich jeder reellwertige Whitneysche $k$-Jet auf einer abgeschlossenen Teilmenge $A\subseteq\mathbb{R}^n$ zu einer $C^k$-Funktion auf $\mathbb{R}^n$ fortsetzen l\"asst. Ausgehend von Whitneys Originalarbeit beweisen wir analoge Resultate f\"ur Jets und Funktionen mit Werten in einem reellen Hausdorffschen lokalkonvexen topologischen Vektorraum $E$. Im Falle $k<\infty$ erhalten wir einen stetigen linearen Fortsetzungsoperator, also eine stetige lineare Rechtsinverse der Abbildung $C^k(\mathbb{R}^n,E)\to \mathcal{E}^k(A,E),\ f\mapsto ((\partial^{\alpha} f)\vert_A)_{\vert\alpha\vert\leq k}.$ Die Fortsetzung von $E$-wertigen Whitneyschen $\infty$-Jets gelingt uns unter der Annahme, dass $E$ metrisierbar ist. Sei $M$ eine endlichdimensionale $C^k$-Mannigfaltigkeit (welche einen "rauen Rand" haben mag). Wir befassen uns mit der Frage, wie man Whitneysche $k$-Jets, die auf einer abgeschlossenen Teilmenge $A\subseteq M$ definiert sind, zu $C^k$-Funktionen auf $M$ fortsetzen kann. Insbesondere beweisen wir f\"ur $k<\infty$ dass die Einschr\"ankung $C^k(M,E)\to C^k(A,E),\ f\mapsto f\vert_A$ f\"ur jede abgeschlossene Untermannigfaltigkeit $A\subseteq M$ eine stetige lineare Rechtsinverse besitzt, wenn $M$ $C^k$-parakompakt und $A$ lokalkompakt, oder $M$ regul\"ar und $A$ kompakt ist., Comment: 70 pages, in German

If we consider information as the basis of action, it may be of interest to examine the flow and acquisition of information between the actors in traffic. The central question is, which signals an automaton has to receive, decode or send in road traffic in order to act safely and in a conform manner to valid standards. The phenomenon-signal-model is a method to structure the problem, to analyze and to describe this very signal flow. Explaining the basics, structure and application of this method is the aim of this paper. -- Betrachtet man Information als Grundlage des Handelns, so wird es interessant sein, Fluss und Erfassung von Information zwischen den Akteuren des Verkehrsgeschehens zu untersuchen. Die zentrale Frage ist, welche Signale ein Automat im Stra{\ss}enverkehr empfangen, decodieren oder senden muss, um konform zu geltenden Ma{\ss}st\"aben und sicher zu agieren. Das Ph\"anomen-Signal-Modell ist eine Methode, das Problemfeld zu strukturieren, eben diesen Signalfluss zu analysieren und zu beschreiben. Der vorliegende Aufsatz erkl\"art Grundlagen, Aufbau und Anwendung dieser Methode., Comment: 28 pages, 6 figures, in German

It is well known that rightly applied reverse auctions offer big commercial potential to procurement departments. However, the sheer number of auction types often overwhelms users in practice. And since the implications of a wrongly chosen auction type are equally well known, the overall usage of reverse auctions lacks its potential significantly. In this paper, a novel method is being proposed that guides the user in selecting the right combination of basic auction forms for single lot events, considering both market-, as well as supplier-related, bijective criteria., Comment: 32 pages, in German, 3 figures, 9 tabels

The transition of our energy system to renewable energies is necessary in order not to heat up the climate any further and to achieve climate neutrality. The use of wind energy plays an important role in this transition in Germany. But how much wind energy can be used and what are the possible consequences for the atmosphere if more and more wind energy is used?, Comment: 10 pages, 4 figures, 1 table.

We extend the Weierstrass-Kerner method by applying the Chebychev method to the function F that Kerner has used to show that the formula of Weierstrass actually is the Newton method applied to that F. The resulting method is already known but we want to present the process in one go and in a detailed way., Comment: 14 pages, in German language

Mathematical modelling and ethics have more touching points than most of us would like to admit. Everyday decisions are often reasoned by mathematical arguments. Mathematics teachers belong to those mathematically literate, who must point out mistakes in public discussions and reflect on them in their teaching to educate students to become critical thinkers. Ethical questions arise in mathematical modelling problems from two possible contexts. The first question is what values are reflected in the modelling problem. The other question is about the ethical implications of applying mathematical models to real problems., Comment: in German language

Quantum computers could break currently used asymmetric cryptographic schemes in a few years using Shor's algorithm. They are used in numerous protocols and applications to secure authenticity as well as key agreement, and quantum-safe alternatives are urgently needed. NIST therefore initiated a standardization process. This requires intensive evaluation, also with regard to performance and integrability. Here, the integration into TLS 1.3 plays an important role, since it is used for 90% of all Internet connections. In the present work, algorithms for quantum-safe key exchange during TLS 1.3 handshake were reviewed. The focus is on the influence of dedicated network parameters such as transmission rate or packet loss in order to gain insights regarding the suitability of the algorithms under corresponding network conditions. For the implementation, a framework by Paquin et al. was extended to emulate network scenarios and capture the handshake duration for selected algorithms. It is shown that the evaluated candidates Kyber, Saber and NTRU as well as the alternative NTRU Prime have a very good overall performance and partly undercut the handshake duration of the classical ECDH. The choice of a higher security level or hybrid variants does not make a significant difference here. This is not the case with alternatives such as FrodoKEM, SIKE, HQC or BIKE, which have individual disadvantages and whose respective performance varies greatly depending on the security level and hybrid implementation. This is especially true for the data-intensive algorithm FrodoKEM. In general, the prevailing network characteristics should be taken into account when choosing scheme and variant. Further it becomes clear that the performance of the handshake is influenced by external factors such as TCP mechanisms or MTU, which could compensate for possible disadvantages due to PQC if configured appropriately., Comment: Master's thesis, 160 pages, in German

Nichtverbale Signale sind ein elementarer Bestandteil der menschlichen Kommunikation. Sie erf\"ullen eine Vielzahl von Funktionen bei der Kl\"arung von Mehrdeutigkeiten, der subtilen Aushandlung von Rollen oder dem Ausdruck dessen, was im Inneren der Gespr\"achspartner vorgeht. Viele Studien mit sozial-interaktiven Robotern zeigen, dass vom Menschen inspirierte Bewegungsmuster \"ahnlich interpretiert werden wie die von realen Personen. Dieses Kapitel erl\"autert daher die wichtigsten Funktionen, welche die jeweiligen Bewegungsmuster in der Kommunikation erf\"ullen, und gibt einen \"Uberblick dar\"uber, wie sie auf Roboter \"ubertragen werden k\"onnen. -- Non-verbal signals are a fundamental part of human communication. They serve a variety of functions in clarifying ambiguities, subtly negotiating roles, or expressing what is going on inside the interlocutors. Many studies with socially-interactive robots show that human-inspired movement patterns are interpreted similarly to those of real people. This chapter therefore explains the most important functions that the respective movement patterns fulfill in communication and gives an overview of how they can be transferred to robots., Comment: 12 pages, in German language, 4 figures

During the application of chemical pesticides, distance requirements have to be considered. However, these have to be determined and considered by the farmer manually. To support the farmer the Pesticide Application Manager (PAM)-Projects were conducted and a decision support system was developed. A part of this system, the distance requirements service was developed at the KTBL. To provide this service, the PAM-prozess is conducted: the pesticide registration data provided via REST-API is crawled, then the data is mapped into an ontology using rmlmapper and made availabe in a machine readable and application-independent form via a SPARQL-Endpoint., Comment: 14 Pages, in German language, 6 figures

Due to increasing numbers of product piracy worldwide, a cost-effective method for verifying the origin of a product is to be developed. For this purpose, a certificate of authenticity can be created using precisely measurable, unique properties of special physical objects that are difficult to reconstruct. In the context of the present work, this is a counterfeit-proof label composed of randomly distributed gold nanospheres or rods in a semi-transparent material. The characteristic positioning of the label's elements can be precisely measured using a smartphone's camera and additional technologies. This can create an offline usable verification method for the general public without the need for an existing network connection. The present work provides a first part of the proof of concept that such a system and especially the associated algorithmic computation method can be implemented and efficiently used in a mobile application. In addition, a method suitable in practice for transmitting and securing the required information is determined in each case. Furthermore, the results of the validation of counterfeit-proof product labels are analyzed in detail and existing weaknesses are pointed out. -- Auf Grund weltweit steigender Zahlen der Produktpiraterie soll ein kosteng\"unstiges Verfahren zur Verifizierung der Herkunft eines Produktes entwickelt werden. Daf\"ur l\"asst sich durch exakt messbare, einzigartige, jedoch schwer rekonstruierbare Eigenschaften spezieller physischer Objekte ein Echtheitszertifikat kreieren. Dieses ist im Kontext der vorliegenden Arbeit ein f\"alschungssicheres Label, das sich in einem semi-transparenten Material aus zuf\"allig verteilten Goldnanok\"ugelchen oder -st\"abchen zusammensetzt. Die charakteristischen Positionierungen der Elemente des Labels lassen sich mit der Kamera eines Smartphones und zus\"atzlichen Technologien pr\"azise messen. Dadurch kann f\"ur die breite Bev\"olkerung ohne die Notwendigkeit einer bestehenden Netzwerkverbindung ein offline verwendbares Verifikationsverfahren erschaffen werden. Die vorliegende Arbeit liefert einen ersten Teil des Machbarkeitsnachweises, dass ein derartiges System und insbesondere das damit einhergehende algorithmische Berechnungsverfahren in einer mobilen Applikation implementier -- und effizient einsetzbar ist. Zudem wird je eine in der Praxis geeignete Methode zur \"Ubermittlung und Sicherung der ben\"otigten Informationen eruiert. Des Weiteren werden die Resultate der Validierung von f\"alschungssicheren Produktlabeln ausf\"uhrlich analysiert und vorhandene Schw\"achen aufgezeigt., Comment: Thesis for: Informatik Bachelor; Advisor: Dr. Markus Friedrich, Dr. Sebastian Feld, Prof. Dr. Dr. Ulrich R\"uhrmair; in German

Do our physics curricula provide the appropriate data management competences in a world where data are considered a crucial resource and substantial funding is available for building a national research data infrastructure (German: Nationale Forschungsdateninfrastuktur = NFDI)? Although basic data evaluation and systematic documentation are practiced when students first come into contact with data, particularly in experimental physics lab courses, they do not meet the increasing demands of research and professional practice to deal with the analysis of huge datasets. In many cases, the problem starts with the fact that there is no consensus on a suitable entry-level programming language. At the Department of Physics at Friedrich-Alexander-Universit\"at Erlangen-N\"urnberg, we have made minor adjustments to the physics curriculum in recent years, which we present in this article. We placed data management competences early in the bachelor curriculum, which has resulted in considerable advantages throughout the further course of studies. The authors feel that students are quickly moving into the fast lane in data management; we can already see in our research groups that they are becoming a driving force towards modern research data management. -- Vermitteln unsere Physikcurricula die passenden Datenverarbeitungskompetenzen in einer Welt, in der Daten als entscheidende Ressource betrachtet werden und erhebliche F\"ordermittel f\"ur eine Nationale Forschungsdateninfrastruktur (NFDI) bereitstehen?

Es scheitert oft schon an einem Konsens \"uber eine geeignete Einstiegsprogrammiersprache. Am Department Physik der Friedrich-Alexander-Universit\"at Erlangen-N\"urnberg haben wir in den letzten Jahren kleinere Anpassungen im Physikcurriculum vorgenommen, die wir in diesem Artikel vorstellen. Datenkompetenz wurde fr\"uh im Bachelorstudium platziert, woraus sich erhebliche Vorteile f\"ur den weiteren Studienverlauf ergeben haben. Die Autoren k\"onnen sich des Eindrucks nicht erwehren, dass die Studierenden in puncto Datenkompetenz schnell auf die \"Uberholspur gehen; wir sehen bereits jetzt in unseren Arbeitsgruppen, dass sie sich als treibende Kr\"afte hin zu einem modernen Forschungsdatenmanagement erweisen., Comment: 10 pages, 3 figures, in German

This work reports on setup, characterisation and data processing of a true quantum random number generator. As a randomness source a pure quantum vacuum state of light is used, which is amplified by a laser beam. Performance and behaviour of the system as well as parasitic errors are investigated. For an optimized exploitation of the data they are Fourier-transformed and processed further as frequency amplitudes. The extractable entropy in that data is calculated to allow for elimination of non-random signal contributions by hashing. The system is able to produce true and unique random numbers at a rate of 25 Gbit/s and thus outperforms previous implementations considerably., Comment: Bachelor thesis at Friedrich-Alexander-Universit\"at Erlangen-N\"urnberg from September 22nd 2011 (in German)

Data warehouse, data lake, data lakehouse, data mesh ... many new names for analytical data architectures are currently circulating in the scene. But are the various approaches really so different? This article attempts a structured comparison of the different architecture paradigms, methodically based on DAMA-DMBOK and ArchiMate. Differences, similarities and dependencies as well as overlapping architectural building blocks are worked out and illustrated. This results in a first orientation guide for the choice of the right analytical data architecture for the respective use case. -- Data Warehouse, Data Lake, Date Lakehouse, Data Mesh ... in der Szene kursieren derzeit viele neue Namen f\"ur analytische Datenarchitekturen.

The digital transformation leads to fundamental change in organizational structures. To be able to apply new technologies not only selectively, processes in companies must be revised and functional units must be viewed holistically, especially with regard to interfaces. Target-oriented management decisions are made, among other things, on the basis of risk management and compliance in combination with the internal control system as governance functions. The effectiveness and efficiency of these functions is decisive to follow guidelines and regulatory requirements as well as for the evaluation of alternative options for acting with regard to activities of companies. GRC (Governance, Risk and Compliance) means an integrated governance-approach, in which the mentioned governance functions are interlinked and not separated from each other. Methods of artificial intelligence represents an important technology of digital transformation. This technology, which offers a broad range of methods such as machine learning, artificial neural networks, natural language processing or deep learning, offers a lot of possible applications in many business areas from purchasing to production or customer service. Artificial intelligence is also being used in GRC, for example for processing and analysis of unstructured data sets. This study contains the results of a survey conducted in 2021 to identify and analyze the potential applications of artificial intelligence in GRC., Comment: in German (55 pages) and in English (55 pages), total 110 pages, 32 figures.
