This article presents a heuristic view that shows that the inner states of consciousness experienced by every human being have a physical but imaginary hypercomplex basis. The hypercomplex description is necessary because certain processes of consciousness cannot be physically measured in principle, but nevertheless exist. Based on theoretical considerations, it could be possible - as a result of mathematical investigations into a so-called bicomplex algebra - to generate and use hypercomplex system states on machines in a targeted manner. The hypothesis of the existence of hypercomplex system states on machines is already supported by the surprising performance of highly complex AI systems. However, this has yet to be proven. In particular, there is a lack of experimental data that distinguishes such systems from other systems, which is why this question will be addressed in later articles. This paper describes the developed bicomplex algebra and possible applications of these findings to generate hypercomplex energy states on machines. In the literature, such system states are often referred to as machine consciousness. The article uses mathematical considerations to explain how artificial consciousness could be generated and what advantages this would have for such AI systems., Comment: 7 pages, in German language. 1 figure

The aim of the work is to present an alternative approach to recording and evaluating student performance that enables sustainable performance recording with the possibility of integrating practical components in particular. The intended result is a digital portfolio with work samples - and not just certificates, which can be understood as a portfolio examination in the context of academic assessment. This is more about the recording, evaluation and certification of learning progress and competencies than the selective evaluation of a performance review, as is the case today, for example, with the submission of final theses. The idea is to expand and later replace final papers and performance tests, particularly in higher semesters, and instead introduce electronically recorded portfolio examinations - based on the example of teaching projects. Technologically, the approach is based on blockchain and wallets/repositories and, in the broadest sense, on an implementation of smart contracts. The technological approach of smart contracts enables a high degree of traceability and transparency with little administrative effort. It also offers secure certification of services by the provider. It should be clearly stated that neither the portfolio examination nor the administration of academic achievements with smart contracts is the original idea, but rather the change in the recording of academic achievements towards an alternative approach to the recording and evaluation of student performance, which enables sustainable performance recording with the possibility of integrating practical components in particular. The desired result is a digital portfolio with work samples. The primary aim of this idea sketch is to develop an individualized performance record for students, which can also contribute to making performance more transparent and comprehensible., Comment: in German language

As part of the automation of commercial vehicles, the number of assistance systems in this field is continuously increasing. The semitrailer plays an important role for the vehicles driving dynamics due to its highly varying loads and the large proportion to the total mass of the truck-semitrailer, especially when it is fully loaded. To create a basis for further development of assistance systems for the semitrailer, this paper presents a two-track model which includes the lateral and roll dynamics of the semitrailer. This enables the future development of observer and filter-based estimation of vehicle states and parameters, which are impossible or very difficult to measure. For offline identification of the unknown model parameters, a Particle-Swarm-Optimization (PSO) algorithm will be used. The validation of the model is based on measurements from a test vehicle. The focus is on the lateral and vertical tire forces of the semitrailer, which are measured at the test vehicle using strain gauges., Comment: in German language. VDI Mechatroniktagung 2021

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

Root Cause Analysis (RCA) is a quality management method that aims to systematically investigate and identify the cause-and-effect relationships of problems and their underlying causes. Traditional methods are based on the analysis of problems by subject matter experts. In modern production processes, large amounts of data are collected. For this reason, increasingly computer-aided and data-driven methods are used for RCA. One of these methods are Causal Discovery Algorithms (CDA). This publication demonstrates the application of CDA on data from the assembly of a leading automotive manufacturer. The algorithms used learn the causal structure between the characteristics of the manufactured vehicles, the ergonomics and the temporal scope of the involved assembly processes, and quality-relevant product features based on representative data. This publication compares various CDAs in terms of their suitability in the context of quality management. For this purpose, the causal structures learned by the algorithms as well as their runtime are compared. This publication provides a contribution to quality management and demonstrates how CDAs can be used for RCA in assembly processes., Comment: in German language

The article presents some current observations (as of April 10, 2024) on the integration of AI-generated images within processes of media convergence. It draws on two different concepts of intermediality. Primary intermediality concepts are motivated by the object when a new type of technology develops the potential to become socially relevant as a media form and thus a socially, politically, or culturally important communicative factor. Due to their uncertain 'measurements' within the wider media ecology, however, the new, still potential media form appears hybrid. The "inter-" or "between-" of this initial intermediality moment thus refers to the questionable "site" and the questionable description of the potential media form between already existing technologies and cultural forms and their conceptual measurements. For secondary concepts of intermediality, in contrast, it can be assumed that the boundaries of media forms and their application have already been drawn and are reasonably undisputed. This then raises the question of intentional and staged references to AI imagery within other media forms and pictures. The article discusses indicators of both intermediality moments using current examples and controversies surrounding AI images. The thesis is that there can be no talk of a seamless 'integration' of AI images into the wider media landscape at the moment (within films, comic books, or video games, for example) - as one of countless other image production techniques - and that the medial 'site' of AI image circulation - at least where it is not a matter of deception, but rather their conscious use as AI images - especially in social media communication and in fan cultures, but with repercussions for the more general media ecology and image interpretation, insofar as the suspicion that an image could be AI-generated is now increasingly present as a "hermeneutics of suspicion"., Comment: in German language

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.

In diesem Beitrag f\"uhren wir deutsche Terminologie f\"ur SOTIF-Betrachtungen ein und setzen uns im Zuge einer Anwendung kritisch mit der STPA-Theorie auseinander, wobei wir begleitend methodische Erg\"anzungen anregen., Comment: The final publication is available at www.degruyter.com, published in at - Automatisierungstechnik, in German

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

Stereotype Vorstellungen von Mathematik und Mathematiker*innen beeinflussen das Interesse von Jugendlichen an MINT-F\"achern. Daher pl\"adiert dieser Beitrag daf\"ur, popul\"are Filme und erfolgreiche Serien nicht nur im Fremdsprachenunterricht, sondern auch im Mathematikunterricht einzusetzen. Durch die Analyse audiovisueller Medien im Unterricht k\"onnen verzerrte Darstellungen \"uber Mathematiker*innen erkannt, die Gr\"unde daf\"ur benannt und alternative Sichtweisen entwickelt werden. Dies tr\"agt dazu bei, das Bild der Mathematik zu entmystifizieren und den Spa{\ss} an Mathe und Englisch zu f\"ordern. Die Einbindung sozialwissenschaftlicher Themen steigert zudem die Motivation der Sch\"uler*innen., Comment: 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. Grundvoraussetzung f\"ur eine synergetische Zusammenarbeit aller Akteure ist die Kommunikation, welche neben verbalen auch nonverbale Interaktionen umfasst. Um eine nonverbale Interaktion zu erm\"oglichen, m\"ussen Maschinen in der Lage sein, menschliche Bewegungen zu erfassen und zu verstehen. Dieser Beitrag stellt die laufende Grundlagenforschung zur Analyse menschlicher Bewegungen mittels sensorgest\"utzter Aktivit\"atserkennung vor und zeigt Ankn\"upfungspunkte f\"ur einen Transfer in industrielle Anwendungen. Im Fokus steht die Praxistauglichkeit der Aktivit\"atserkennung durch die Hinzunahme weiterer Datenstr\"ome wie beispielsweise den Positionsdaten logistischer Objekte und Hilfsmitteln, d. h. dem Kontext, in dem eine gewisse Aktivit\"at ausgef\"uhrt wird., Comment: in German language. 30.

We are in the process of creating a database of digital games from the DACH region. This article provides an insight into the context in which it was created and the underlying methodological considerations behind the games database. The database was compiled collaboratively and lists digital games developed in Germany, Austria and Switzerland up to the year 2000. In this report, we outline our initial considerations and the various stages of realisation as well as the input data on which the database was built, the aims of the data model and the difficulties we faced during the creation process. We then pin down the current status of the games database and give an outlook on the project's future plans. -- Unser Werkstattbericht gibt Einblick in den Entstehungskontext sowie die zugrundeliegenden methodischen \"Uberlegungen hinter der von den Autor*innen publizierten Spieledatenbank. Diese wurde kollaborativ erarbeitet und f\"uhrt digitale Spiele, die in Deutschland, \"Osterreich und der Schweiz bis zum Jahr 2000 entwickelt wurden. In diesem Bericht skizzieren wir neben unseren Ausgangs\"uberlegungen und den verschiedenen Arbeitsschritten bei der Realisierung au{\ss}erdem auch, auf welcher Datenbasis die Datenbank aufgebaut und gepr\"uft wurde, was die Ziele des Datenmodells sind und mit welchen Schwierigkeiten wir im Prozess der Erstellung konfrontiert waren. Hiernach ordnen wir den aktuellen Stand der Spieledatenbank ein und geben einen Ausblick auf die weiteren Pl\"ane des Projekts., Comment: 11 pages, in German language

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
