T1 - Energy Technologies For Decarbonizing The Steel Processing Industry – A Numerical Study
JF - IFAC-PapersOnLine
N2 - This study analyzes approaches to decarbonize the energy supply of the secondary steel processing industry. Therefore, real data from a secondary steel production company is used in combination with state-of-the art low carbon energy supply technologies. Also, the use of waste heat from a pusher furnace for process integration is considered. The developed temporal process model allows holistic optimizing and expanding the steel making process system regarding techno-economic criteria. As we show, implementing the annual heat demand of a municipality shows that a nearly 100 % self-sufficient heat supply is possible.

T1 - Evaluation of AI-based use cases for enhancing the cyber security defense of small and medium-sized companies (SMEs)
JF - IS and T International Symposium on Electronic Imaging Science and Technology
JF - IS&T International Symposium on Electronic Imaging : Mobile Devices and Multimedia: Enabling Technologies, Algorithms, and Applications, 2022
N2 - Companies are increasingly facing the challenges of a persistent cyber threat landscape. By means of AI, cyber attacks can be efficiently conducted more successful through offensive AI. As for cyber defense, AI can be also utilized against cyber threats (defensive AI). Due to limited resources, especially in small and medium-sized companies (SMEs), there is a need to deploy more effective defensive cyber security solutions. Precisely, the adaptation of AI-based resilient defenses must be driven forward. Therefore, the aim of this paper is to identify and evaluate AI-related use cases with a high impact potential on the cyber security level, while being applicable to SMEs at the same time. In order to reach the research goal, an extensive literature review of several online catalogs, surveys and online platforms was conducted. In conclusion, seven crucial AI-based security features were outlined that are providing a high impact potential to the security level for SMEs. Afterwards, the results are discussed and set into a broader context. Even though AI-based security solutions are providing a large range of advantages, certain challenges and barriers using AI-related security applications are addressed in the paper as well. A high need for usable state of the art AI based cyber security solution for SMEs was identified.

T1 - Disruption of Africa's education systems and economic development due to overpopulation
N2 - Education lies at the foot of economic growth and human development. However, an increase in population tends to put a strain on existing education systems, especially in Africa where most countries are characterized by slow economic development, rapid population growth rates and a median age just shy of 20 years. Due to the slow rate of economic growth, many African countries lack the financial capability to provide proper education for their ever-growing populations or even already overpopulated regions, many of which have people who have reached the appropriate school-going age. This leads to a series of disruptive impacts on the education systems resulting in a people who are poorly or improperly educated, and thus are not equipped with the necessary skills required for the vast technical, professional and ever modernizing high-skill job markets such as construction, economic and technical professions, teaching occupations and so on, all of which drive economic growth and development. Therefore, we can see that rapid population growth, if left unchecked, may lead to overpopulation scenarios which could have a negative disruptive impact on education and human development, both of which are important factors necessary for economic growth.

T1 - Absence of external resources in Germany
BT - An analysis about the deglobalization of resources in Germany based on the case studies oil and gas and rare earths
N2 - This scientific paper deals with the question of to what extent the deglobalization of raw materials will have an impact on Germany. For this purpose, a general understanding of the terms “globalization” and “deglobalization” will be provided. In addition, the drivers and challenges of (de)globalization are explained in more detail. The question was then examined based on specific case studies, which are decisive for today's prosperity and are predominantly imported. This includes gases, oils, and rare earths. The paper distinguishes between the effects of a loss of these resources on Germany, if the deglobalization takes place slowly and planned or unplanned and fast. The effects are then considered at three different levels: at the government level, at the corporate level, and at the population level. At the corporate level, the focus was primarily on the largest German industries. Each of the case studies ends with possible hypothetical scenarios that do not have to happen but could happen in the worst case. The scenarios show how bad things can get and provide an answer to the scientific question of how deglobalization in the case study could affect Germany.

T1 - Threats provided by artificial intelligence that could disrupt the democratic system
N2 - This research paper examines the potential consequences of AI technology on democratic systems. The study focuses on two main areas: the weakening of the media and the emergence of "smart dictatorship." The paper examines the ways in which AI can be used to supervise, manipulate, and frustrate the media, thereby weakening its role as a check on government and corporate power. The study also explores how AI technology can be used to create an "omnidirectional monitoring" society, where individuals are constantly monitored and controlled through the use of "panopticon" techniques and "social bots". This can lead to the emergence of a "postdemocratic" society, characterized by growing inequality, dehumanization, and the
manipulation of information on online media platforms. The research methodology adopted in the study is qualitative, using expert interviews with three experts who
discussed the overall use of AI and its disruptive effects on democracy, such as the creation of fake news, filter bubbles, and algorithm bias. In conclusion, this research highlights the need for increased awareness and regulation of AI technology to ensure its responsible use and to protect democratic values.

N2 - Der Einfluss von Technik in der Medizin wird immer deutlicher. Hierbei steigt auch im gleichen Maß die Bedrohung auf das Gesundheitswesen durch Cyberkriminalität. [1] Diese Arbeit umfasst eine Schwachstellenbetrachtung und Analyse der Kommunikation zweier B. Braun Infusionspumpen und dem dazugehörigen Konfigurationswerkzeug, der „Online-Suite“. Hierbei wurde ein Fokus auf vor allem drei Untersuchungsmethoden gelegt: 1. Ein Portscan mittels „Nmap“, welcher bereits erste, leicht einsehbare Informationen über die verwendeten Ports und Dienste aufdecken sollte. 2. Ein Schwachstellenscan durchgeführt mit „GVM/OpenVAS“, welcher die einzelnen Schwachstellen der Dienste und Software an Hand von einem „CVSS-Wert“ bewertet. 3. Eine Betrachtung des Netzwerkverkehrs in Wireshark, um den Aufbau der Kommunikation zu analysieren. Hierbei ergaben sich diverse Sicherheitsrisiken und Probleme. Diese können im schlimmsten Fall auch die Sicherheit des Patienten beeinflussen. Besonders häufig wurden hierbei Schwachstellen gefunden, welche durch veraltete und nicht weiter unterstützte Software bedingt waren.

T1 - Detektion von Ransomware in der IT-Systemlandschaft bei Betreibern Kritischer Infrastruktur
N2 - Ransomware-Angriffe auf Kritische Infrastrukturen, wie Energie- oder Wasserversorgung, treten immer häufiger auf und stellen eine große Bedrohung für die Betreiber und die Bevölkerung dar. Eine verlässliche und frühzeitige Erkennung dieser Angriffe ist somit ein wichtiger Bestandteil von IT-Sicherheitskonzepten.
Ziel dieser Arbeit ist die Klärung der Fragen, welche Methoden zur Erkennung von Ransomware eingesetzt werden und welche Indikatoren für Ransomware-Angriffe mithilfe eines Angriffserkennungssystems in einer nachgebildeten IT-KRITIS-Infrastruktur erkannt werden können.
Es wurden Methoden zur Detektion von Malware und Ransomware genauer betrachtet.
In einem Experiment wurde die Erkennung von Ransomware mithilfe eines Angriffserkennungssystems (Elastic Stack) untersucht. Das Ergebnis dieser Arbeit zeigt, dass die Erkennung sowohl mit allgemeinen Detektionsansätzen als auch mit auf Ransomware spezialisierten Methoden erfolgen kann.
Aus dem Experiment geht hervor, dass die Detektion von Ransomware-Angriffen mithilfe eines Angriffserkennungssystems in der Praxis erfolgreich ist. Indikatoren für RansomwareAngriffe werden sowohl auf Systemebene (Prozesse, Dateioperationen, Registry-Änderungen etc.) als auch auf Netzwerkebene (C2-Kommunikation, auffällige DNS-Anfragen, IPAdressen etc.) erkannt.

T1 - Integration von Endnutzer Netzwerkgeräten in zentralisierte Protokoll Management Systeme am Beispiel der FRITZ!Box
N2 - Diese Bachelorarbeit untersucht die Einbindung eines typischen Endnutzer Netzwerkgerätes in ein bestehendes Protokollierungssystem. Aufgrund des erhöhten Anteils an Mitarbeitern im Homeoffice in deutschen Firmen sind die Heimnetzwerke ein bedeutend wichtigerer Bestandteil der Firmensicherheit und es soll untersucht werden, wie übliche Heimnetzwerkgeräte in die Sicherheitsstrukturen der Firmen eingebunden werden können.
Zu diesem Zweck wird ein Proof-of-Concept basierend auf den Technologien TR-064, zur Kommunikation mit der FRITZ!Box und Syslog, zur Kommunikation mit einem Protokollierungssystem entwickelt.
Anhand dieses Prototypen lässt sich feststellen, dass eine solche Einbindung zwar einfach umzusetzen ist, aber auf dieser keine effektive Überwachung aufgebaut werden kann. Die Ursache dafür ist der Umstand, dass TR-064 nur einen Bruchteil der Logdaten von der FRITZ!Box zurücksendet.

T1 - Untersuchung der Rotorfestigkeit von permanenterregten Synchronmaschinen mit vergrabenen Magneten
N2 - Diese Projektarbeit behandelt die mechanische Simulation der Rotoren von permanenterregten Synchronmaschinen für den Festigkeitsnachweis. Hierzu wird die Finite-Elemente-Methode mit dem Programm CalculiX verwendet. Als Beispiel wird der Elektromotor des Toyota Prius II im Detail betrachtet. Hierbei werden die unterschiedlichen Lasten modelliert, dazu zählen neben der Zentrifugalkraft auch der Innendruck durch eine Presspassung sowie die elektromagnetischen Kräfte. Für die Modellierung von Kräften auf der Rotoroberfläche wird eine Methodik zur Umsetzung in CalculiX entwickelt und anhand eines Beispielmodells demonstriert. Der angestrebte Festigkeitsnachweis kann im Rahmen dieser Arbeit erbracht werden. Weiterhin wird gezeigt, dass der Einfluss der elektromagnetischen Kräfte im Arbeitspunkt mit der höchsten Drehzahl sehr gering ausfällt. Insgesamt bietet diese Arbeit die Grundlagen für mechanische Modellierungen von Rotoren unter Berücksichtigung aller Kräfte. Dies kann direkt auf andere Elektromotoren angewendet werden.

T1 - Datenmodellinterne Revisionshistorie für nebenläufige Geschäftsprozesse am Fallbeispiel der Verwaltung von Studiengangscurricula
N2 - Die Versionierung von Daten ist ein hochkomplexes Problem, das viele verschiedene
Aspekte berücksichtigen muss. Daher ist in diesem Bereich bisher noch kein univer-
sell anwendbarer Ansatz beschrieben worden. Verschiedene Autoren haben sich an einer
Lösung versucht und Herangehensweisen für ihre eigenen Anwendungsfälle entwickelt.
In dieser Arbeit wird ein neuer Ansatz anhand eines Fallbeispiels vorgestellt. Der An-
satz zielt darauf ab, Daten- und Versionierungsstrukturen in einem relationalen Da-
tenmodell zu vereinigen und dabei eine einfache Integration von Geschäftsprozessen
zu ermöglichen. Insbesondere wird darauf geachtet, dass die Erzwingung des korrekten
Ablaufs von Geschäftsprozessen durch eine maschinelle Umsetzung derselben möglich
ist. Das Datenmodell beinhaltet eine vollständige Versionierungshistorie in Form eines
gerichteten zyklenlosen Graphen. Hiermit bietet es eine breit anwendbare Lösung zur
Datenversionierung, die zudem gut in bestehende Abläufe und Datensätze integrierbar
ist. In dieser Arbeit wird das kombinierte Datenmodell vorgestellt und anhand von ge-
nerischen Beispielen erläutert. Zudem wird die Funktionalität des Ansatzes anhand des
Fallbeispiels der Verwaltung der Studiengangscurricula des Fachbereichs Informatik und
Medien der Technischen Hochschule Brandenburg belegt. Hierbei wird auch die Integra-
tion von Geschäftsprozessen und die Nutzbarkeit in der tatsächlichen Datenverwaltung
dargestellt.
N2 - Versioning of Datasets is a highly complex problem whose solutions are required to take
many different aspects into account. As such, no universally applicable approach has
been published yet. Various authors have tried and developed solutions for their own
use cases. In this thesis, we present our approach based on our use case. The approach
shown here aims to unify structures for data persistence and version control into a single
data model and to allow a seamless integration of business processes. In particular, the
aim is to ensure that an enforcement of business processes via an automated execution
of said processes is easily possible. The data model delivers a complete version history
as a directed non-cyclic graph. As such, it offers a widely applicable solution for data
versioning in small systems, which is also easily integratable into existing data sets,
processes and structures. This thesis presents the combined data model and explains
its appliation using generic examples. Afterwards, the funcionality of the approach in
a real-life setting is demonstrated with our use case of managing the curricula of the
Department of Computer Science and Media at the Brandenburg University of Applied
Sciences. In this, the integration of business processes and the usage in actual data
mangement is also demonstrated.

T1 - Implementierung eines Stacks zum Erzeugen, Verarbeiten und Visualisieren von Telemetriedaten für ein Microservice basiertes System
N2 - Einsicht in die Abläufe und Leistung heutiger Software und verteilter Systeme zu erlangen, wird durch stetig steigende Komplexität zunehmend erschwert. Die Firma Peterson Technologies GmbH implementierte zur Linderung dieser Problematik ein internes Telemetriesystem. Ziel dieser Arbeit ist es, das System auf Wunsch der Firma durch ein neues zu ersetzen, um so die Überwachung zu verbessern und aktuellere Software zu verwenden. Nach einer Untersuchung des vorherigen Systems werden Prioritäten festgelegt, welche die spätere Nutzung, Instandhaltung und Erweiterung des neuen Systems erleichtern sollen. Darauf folgen die Planung seiner Architektur, die Auswahl und Implementierung der Software und schließlich das Erzeugen einer einfachen Dokumentation. Der resultierende Telemetriestack ist funktionstüchtig und erfüllt die Vorstellungen der Firma. Dennoch weist er einige Probleme, wie beispielsweise eine hohe CPU Belastung auf, welche zusammen mit Möglichkeiten der Verbesserung und Erweiterung abschließend betrachtet werden.

T1 - Bewertung des Potentials von Network Access Control (NAC) für die Netzwerksicherheit in modernen IT-Umgebungen mittels vergleichender Betrachtung der beiden Produkte PacketFence und macmon
N2 - In der heutigen digitalisierten Welt spielt die Sicherheit von IT-Infrastrukturen eine
entscheidende Rolle. Diese Bachelorarbeit untersucht das Potenzial von Network
Access Control (NAC) als eine IT-Lösung zur Verbesserung der Netzwerksicherheit in
modernen IT-Umgebungen. Dabei steht die Zugriffskontrolle von Personen und
Geräten im Vordergrund. Damit soll erreicht werden, dass unautorisierter Zugriff zum
Netzwerk verhindert wird. Es werden die Begrifflichkeiten, Funktionsweise und
potenzielle Angriffsvektoren von NAC untersucht. Des Weiteren werden die jeweiligen
Funktionen der NAC-Produkte macmon und der Open-Source Lösung PacketFence
gegenübergestellt. Im praktischen Teil der Arbeit werden dann die vorgestellten
Angriffsvektoren an einem Test-Netzwerk durchgeführt und analysiert.
Die Arbeit zeigt, dass NAC eine wichtige Komponente in der Zugriffskontrolle für eine
moderne IT-Infrastruktur ist. Während einige Angriffe auf das Test-Netzwerk
abgewehrt werden konnten, war es dennoch möglich, sich als Angreifer am Netzwerk
anzumelden. NAC ist ein unerlässliches Tool für größere IT-Infrastrukturen, jedoch
erfordert eine korrekte Konfiguration und effektive Nutzung von NAC ein
umfangreiches Wissen über die verschiedenen Aspekte und Themenbereiche der
Netzwerksicherheit.
N2 - In today's digitalized world, the security of IT infrastructures plays a vital role. This
bachelor's thesis examines the potential of Network Access Control (NAC) as an IT
solution to enhance network security in modern IT enviroments. The focus is on access
control for individuals and devices. The goal is to prevent unauthorized network access.
The terminology, functionality, and potential attack vectors of NAC are explored.
Furthermore, the respective functions of the NAC products macmon and the open-
source solution PacketFence are compared. In the practical part of the thesis, the
introduced attack vectors are tested on a lab network and analyzed.
The study shows that NAC is a crucial component in access control for modern IT
infrastructure. While some attacks on the test network were successfully prevented, it
was still possible for an attacker to gain access to the network. NAC is an indispensable
tool for larger IT infrastructures. However proper configuration and effective use of
NAC require extensive knowledge of the various aspects and topics of network security.

T1 - Towards real-time monitoring of metal transfer and melt pool temperature field in gas metal arc directed energy deposition
JF - Welding in the World
N2 - Large three-dimensional metallic parts can be printed layer-by-layer using gas metal arc directed energy deposition (GMA-DED) process at a high deposition rate and with little or no material wastage. Fast responsive real-time monitoring of GMA-DED process signatures and their transient variations is required for printing of dimensionally accurate and structurally sound parts. A systematic experimental investigation is presented here on multi-layer GMA-DED with two different scanning strategies using a high strength low alloy (HSLA) filler wire. The dynamic metal transfer, melt pool temperature field and its longitudinal cross-section, and arc voltage and current are monitored synchronously. The transient arc heat input and the melt pool solidification cooling rate are estimated from the monitored signals. The layer-wise variations of the melt pool dimension, surface temperature profile, thermal cycles, and solidification cooling rate are examined for different scanning strategies. It is comprehended that the part defects can be minimized, and the mass production of zero-defect parts can be achieved in GMA-DED process with synchronized monitoring and assessment of the real-time process signatures.

T1 - An approach for analyzing business process execution complexity based on textual data and event log
JF - Information Systems
N2 - With the advent of digital transformation, organizations increasingly rely on various information systems to support their business processes (BPs). Recorded data, including textual data and event log, expand exponentially, complicating decision-making and posing new challenges for BP complexity analysis in Business Process Management (BPM). Herein, Process Mining (PM) serves to derive insights based on historic BP execution data, called event log. However, in PM, textual data is often neglected or limited to BP descriptions. Therefore, in this study, we propose a novel approach for analyzing BP execution complexity by combining textual data serving as an input at the BP start and event log. The approach is aimed at studying the connection between complexities obtained from these two data types. For textual data-based complexity, the approach employs a set of linguistic features. In our previous work, we have explored the design of linguistic features favorable for BP execution complexity prediction. Accordingly, we adapt and incorporate them into the proposed approach. Using these features, various machine learning techniques are applied to predict textual data-based complexity. Moreover, in this prediction, we show the adequacy of our linguistic features, which outperformed the linguistic features of a widely-used text analysis technique. To calculate event log-based complexity, the event log and relevant complexity metrics are used. Afterward, a correlation analysis of two complexities and an analysis of the significant differences in correlations are performed. The results serve to derive recommendations and insights for BP improvement. We apply the approach in the IT ticket handling process of the IT department of an academic institution. Our findings show that the suggested approach enables a comprehensive identification of BP redesign and improvement opportunities.

T1 - Towards a Framework for Context Awareness Based on Textual Process Data: Case Study Insights
T2 - Lecture Notes in Business Information Processing
N2 - Context awareness is critical for the successful execution of processes. In the abundance of business process management (BPM) research, frameworks exclusively devoted to extracting context from textual process data are scarce. With the deluge of textual data and its increasing value for organizations, it becomes essential to employ relevant text analytics techniques to increase the awareness of process workers, which is important for process execution. The present paper addresses this demand by developing a framework for context awareness based on process executions-related textual data using a well-established layered BPM context model. This framework combines and maps various text analytics techniques to the layers of the context model, aiming to increase the context awareness of process workers and facilitate informed decision-making. The framework is applied in an IT ticket processing case study. The findings show that contextual information obtained using our framework enriches the awareness of process workers regarding the process instance urgency, complexity, and upcoming tasks and assists in making decisions in terms of these aspects.

T1 - The Patellostabilometer: A New Device for Quantification of Mediolateral Patella Displacement
JF - Sensors
N2 - Mediolateral patella displacement is of interest for diagnostics and clinically relevant
research questions. Apart from manual testing, no standardized method is currently available. Proper
quantification of patella mobility is necessary to better understand pathologies at the patellofemoral
joint. Patella mobility was assessed in 25 healthy individuals using a Patellostabilometer, a new
prototype instrument for quantification of the mediolateral patella displacement. The participants
underwent measurements of the mediolateral displacement three times using the Patellostabilome-
ter. A maximal force of 10 N was applied for patella movement. Additionally, leg length and
circumference of the knee, upper- and lower-leg were measured. Lateral patella displacement of
18.27 ± 3.76 mm (range 15.85–20.64 mm, interquartile range (IQR) of 4.79) was measured. The medial
patella displacement showed 24.47 ± 6.59 mm (range 19.29–29.76 mm, IQR of 10.47). The test–retest
measurement error was 2.32 ± 1.76 mm (IQR of 2.38 mm), with five outliers. There was greater
test–retest variability between the measurements of the medial displacement compared to the lateral
one. The test–retest variability reached 7% of the patella displacement. Other parameters provided no
significant correlations. Based on the natural patellofemoral mobility, a precise and clinically relevant
quantification of patella mobility is allowed.

T1 - Application of Text Analytics in Public Service Co-Creation: Literature Review and Research Framework
JF - DG.O 2023: The 24th Annual International Conference on Digital Government Research
N2 - The public sector faces several challenges, such as a number of external and internal demands for change, citizens' dissatisfaction and frustration with public sector organizations, that need to be addressed. An alternative to the traditional top-down development of public services is co-creation of public services. Co-creation promotes collaboration between stakeholders with the aim to create better public services and achieve public values. At the same time, data analytics has been fuelled by the availability of immense amounts of textual data. Whilst both co-creation and TA have been used in the private sector, we study existing works on the application of Text Analytics (TA) techniques on text data to support public service co-creation. We systematically review 75 of the 979 papers that focus directly or indirectly on the application of TA in the context of public service development. In our review, we analyze the TA techniques, the public service they support, public value outcomes, and the co-creation phase they are used in. Our findings indicate that the TA implementation for co-creation is still in its early stages and thus still limited. Our research framework promotes the concept and stimulates the strengthening of the role of Text Analytics techniques to support public sector organisations and their use of co-creation process. From policy-makers' and public administration managers' standpoints, our findings and the proposed research framework can be used as a guideline in developing a strategy for the designing co-created and user-centred public services.

T1 - Wirtschaftsförderung und E-Governance: Von der Resilienz zur Transformation?
T2 - Wirtschaftsförderung in der Krise
N2 - Unsere Welt verändert sich in unterschiedlichen Tempi und Verwerfungstiefen. Dies ist das einzig Verlässliche für Wirtschaft und Gesellschaft.
Zum einen zählt die kreative Zerstörung zum ‚Markenkern‘ marktwirtschaftlicher Systeme. Die Wirtschaftsakteure stehen dadurch an ihrem jeweiligen Standort unter einer Art (produktivem) Dauerstress. Es gibt Gewinner und Verlierer, weil Wettbewerber unterschiedlich erfolgreich kostensenkende Rationalisierungen, technischen Fortschritt und die Erschließung neuer (globaler) Märkte realisieren. Der damit einhergehende Strukturwandel gilt als wirtschaftssystemischer Normalzustand.
Zum anderen gibt es Krisen. Und auch ‚unter Schock‘ (re-)agieren Akteure ungleich, wie die Corona-Pandemie oder abrupte Veränderungen durch die Finanzkrise zeigen. Einige Akteure und Standorte bleiben mit ihrem jeweiligen Profil und Potenzial (weiterhin) produktiv widerstandsfähig. Für andere verschärfen sich der wirtschaftliche Niedergang und dessen Folgen für die Arbeitsmärkte und Lebensqualität der Betroffenen.
Regionale Wirtschaftsförderung unterstützt, dass sich die Wirtschaftsstrukturen an einem Standort überlebensfähig ausrichten. Doch kann sie auch beim Umgang mit Krisen einen Mehrwert erzielen und zählt dies überhaupt zu ihrem Regelauftrag? Und welche Rolle spielt die Digitalisierung? Der Beitrag stellt den sachlogischen Zusammenhang zwischen diesen Teilfragen her und ordnet neuere Ansätze ein. Zudem werden Ansatzstellen aufgezeigt, um die regionale Wirtschaftsförderung praxisorientiert weiterzuentwickeln. ‚Electronic Government‘ (E-Government) beschreibt dabei den Einsatz von Informationstechnik, Telekommunikation und Medien (ITKM) im öffentlichen Sektor, während ‚Electronic Governance‘ (E-Governance) hybride oder private Akteure miteinbezieht.
Der Beitrag ist wie folgt strukturiert: Zunächst werden Schlüsselbegriffe wie Strukturpolitik und Resilienz geklärt und mit den Kontextfaktoren verknüpft, welche die Steuerungslogik von Wirtschaftsförderung bestimmen. Danach wird diskutiert, inwiefern die Wirtschaftsförderung E-Government und E-Governance nutzen kann, um Resilienz zu stärken und möglichst transformativ wirken zu können.

T1 - Effectiveness of massage chair and classic massage in recovery from physical exertion: a pilot study
JF - Journal of Novel Physiotherapy and Rehabilitation
N2 - Quick and cost-effective recovery is foundational to high-quality training and good competition results in today’s sports.
The aim of the research was to elucidate the effects of hand and massage chair massage on the biomechanical parameters of muscles of lower limbs and back, indicators of Pain Pressure Thresholds (PPT) and subjectively perceived fatigue.
A total of 32 female recreational athletes (18 – 50 years old) were assigned to a hand massage, massage chair, or lying down the group. They were measured for muscle biomechanical properties (MyotonPro), PPT (Wagner Instruments) and subjectively perceived fatigue (VAS scale) before and after fatigue tests and treatment. The recovery procedure and subjective satisfaction with treatment were rated on a Likert scale.
Changes in the median value of m. rectus femoris and m. gastrocnemius stiffness with treatment showed that hand massage could be more effective in reducing stiffness, as compared to chair massage.
Hand massage may have benefits for recovery from physical exertion, but due to the individuality of subjects, detailed methodological studies are needed to evaluate the effects of massage chair vs. hand massage.

T1 - Die Grenzen des Auges
JF - Physik Journal
N2 - Mithilfe geeigneter Hilfsmittel lassen sich die Wahrnehmungsgrenzen des Auges überwinden.
Menschliche Augen weisen räumliche, zeitliche und spektrale Begrenzungen auf, welche die Wahrnehmung einschränken. Geeignete optische Geräte und Kameras helfen, diese zu überwinden und eine große Vielfalt an physikalischen Phänomenen für die Lehre zu erschließen.
Die Angaben zu den Anteilen an aufgenommener Information durch die menschlichen Sinnesorgane schwanken meist zwischen etwa 81 und 87 Prozent für die Augen, 10 bis 11 Prozent für die Ohren und dem Rest für schmecken, riechen und tasten. Das Produktmarketing macht sich dies gezielt zunutze. Offensichtlich ist für alle subjektiven Wahrnehmungen unserer Umwelt das Auge sehr wichtig; in Bezug auf räumliche und zeitliche Auflösung sowie spektrale Empfindlichkeit ist es jedoch eingeschränkt. Die dadurch entstehenden Wahrnehmungsgrenzen für physikalische Vorgänge und Objekte lassen sich durch geeignete optische Geräte mit – das Auge ersetzenden – Sensoren in Kamerasystemen überwinden (Abb. 1). Dies erhöht die Zahl beobachtbarer technischer und natürlicher Phänomene und den daraus gewonnenen Informationsgehalt deutlich. Da entsprechende Kameras relativ preiswert sind und sich damit viele einfache Experimente erfolgreich demonstrieren lassen, kann ein gezielter Einsatz die Lehre der Physik an Schulen und in einführenden Vorlesungen an Hochschulen bereichern und den Einstieg in verwandte Gebiete wie die Infrarotastronomie vorbereiten.

N2 - Learning in the workplace is crucial for updating and upskilling the workforce to both new and existing employees. Given the limited opportunities for informal learning due to solitary work conditions or off-site locations, mobile devices like smartphones and wearables such as smart glasses can play a significant role. The aim of this paper is to investigate the extent to which mobile micro-learning can enhance work-related education, with a focus on lightweight, practical applications in learning-deprived environments. Comparative analyses are presented for mobile micro-learning approaches for smartphones and smart glasses based on recent studies, specifically examining their impact on learning and
modes of interaction. Based on good practices of recent MML
implementations, we present principles for implementation and offer lightweight proof-of-concept models for both handheld devices and smart glasses. This knowledge might be relevant for researchers, small and medium-sized enterprises, practitioners, and others involved in knowledge transfer

T1 - Velocity and pressure functions of an oscillating flow in a circular Hele-Shaw cell
JF - Iranian Journal of Physics Research
N2 - In this study, we have investigated the form of velocity and pressure functions of a fluid oscillating between two parallel glass sheets that form a circular Hele-Shaw cell. The flow has been considered to be radial, incompressible and laminar. The time-dependent Navier-Stokes equation has been solved in cylindrical coordinates using Fourier transform, and the oscillating flow velocity across the thickness of the cell has been obtained at different times. The flow velocity function in the unsteady state is related to the vertical component of the coordinates in the form of parabolic functions and also to the inverse of the radial component. The time dependence appears as a simple harmonic with a frequency equal to the oscillation frequency. The velocity of the flow is maximum at the middle of the cell along its height and gradually decreases from the middle towards the top or bottom plane and reaches zero. Pressure does not depend on the height and changes logarithmically with the radius. The dependence of pressure on time is also a simple harmonic with the external frequency, but it has a phase shift with respect to the velocity.

T1 - iPhone12 imagery in scene-referred computer graphics pipelines
JF - Electronic Imaging
N2 - With the release of the Apple iPhone 12 Pro Max in 2020, various features were integrated that make it attractive as a recording device for scene-related computer graphics pipelines. The captured Apple RAW images have a much higher dynamic range than the standard 8-bit images. Since a scene-based workflow naturally has an extended dynamic range (HDR), the Apple RAW recordings can be well integrated. To correctly integrate the iPhone 12 pro Apple RAW data into a scene-related workflow, two command-line software solutions, among others, are dcraw and rawtoaces. In this paper, we concentrate on dcraw. dcraw offers the possibility to export RAW images directly to ACES2065-1. Different images recorded under different lighting conditions are examined to determine which options for the dcraw development produce the best results. Images from five different lighting situations like D65, D60, D55, D50, and 2980K, are examined. The DNG files are developed using different methods within dcraw. The values of the recorded ColorChecker24 patches are compared to reference values derived from BabelColor [1] and ACES [2].

T1 - A qualitative study of LiDAR technologies and their application areas
JF - Electronic Imaging
N2 - In this work, the most relevant 3D LiDAR technologies and their applications in 2022 were investigated. For this purpose, applications of LiDAR systems were classified into the typical application areas "3D modeling", "smart city", "robotics", "smart automotive" and "consumer goods". The investigation has shown that neither "mechanical" LiDAR technologies, nor so-called solid-state LiDAR technologies, nor "hybrid" LiDAR technologies can be evaluated as optimal for the typical application areas. In none of the application areas could all of the elaborated requirements be met. However, the "hybrid" LiDAR technologies such as sequential MEMS LiDAR technology and sequential flash LiDAR technology proved to be among the most suitable for most typical application areas. However, other technologies also tended to be suitable for individual typical application areas. Finally, it was found that several of the LiDAR technologies investigated are currently equally suitable for some typical application areas. To evaluate the suitability, concrete LiDAR systems - of different technologies and properties - were compared with the specific requirements of exemplary applications of an application area. The results of the investigation provide an orientation as to which LiDAR technology is promising for which application area.

T1 - Welche Zertifizierung ist hilfreich für Verbraucher*innen?
BT - Acht Thesen zu wirksamen freiwilligen Zertifikaten von KI-Produkten
N2 - In diesem Whitepaper fokussieren wir uns auf die KI-Verordnung nicht erfasste freiwillige Zertifizierung. Dabei stehen die Interessen und Sichtweisen der Verbraucher*innen im Vordergrund. Als Verbraucher*innen betrachten wir nicht nur die unmittelbaren Nutzer*innen von KI-Systemen, sondern auch Privatpersonen, die indirekt von KI-Ergebnissen betroffen sein können. Zudem berücksichtigen wir Menschen in der Rolle als souveräne Datensubjekte, deren personenbezogene Daten in die Entwicklung von KI-Systemen einfließen. Dieses breite Verständnis des Verbraucher*innenbegriffs entspricht dem Selbstverständnis des Zentrums für vertrauenswürdige Künstliche Intelligenz (ZVKI). Wir stellen Thesen auf, wie freiwillige Zertifizierungen von KI-Systemen für Verbraucher*innen nützlich sein können. Die im Verlauf vorgestellten und begründeten acht Thesen wurden in einer Reihe von interdisziplinären Workshops erarbeitet. Dabei identifizierten wir Herausforderungen einer KI-Zertifizierung aus Verbraucher*innensicht und präzisierten diese iterativ. Die Gruppendiskussionen dienten als Grundlage dieses Whitepapers und bauten auf Erkenntnissen der Fach-Arbeitsgruppe „KI Zertifizierung“ des ZVKI auf. Alle Co-Autor*innen waren an der Erstellung des finalen Texts beteiligt. Die aufgestellten Thesen thematisieren grundlegende Anforderungen an eine KI-Zertifizierung aus einer übergeordneten Perspektive, unabhängig von den spezifischen Details einer KI-Anwendung. Somit liefern sie keine Aussagen zu konkreten Inhalten der Zertifizierung. Detaillierte Empfehlungen setzen eine umfassende Analyse von Einsatzfällen voraus, die in diesem Rahmen nicht geleistet werden kann.

T1 - DIN SPEC 92001-3 Artificial Intelligence - Life Cycle Processes and Quality Requirements - Part 3: Explainability
N2 - DIN SPEC 92001-3 Artificial Intelligence – Life Cycle Processes and Quality Requirements. Artificial Intelligence has become a game-changer, but its impact must be approached responsibly. This is the third document in a series, and it aims to ensure that AI systems are developed, deployed, and used efficiently, responsibly, and in a trustworthy way. It focuses on “Explainability” – the ability to understand how AI makes decisions.

T1 - Фоточувствительные структуры с каскадными концентраторами излучения на основе коллоидных квантовых точек халькогенидов металлов
JF - Journal of the Russian Universities Radioelectronics
N2 - The problem of increasing the efficiency of existing photodetectors and creating their new types attracts much research attention. Among new photodetector types are photosensitive structures based on cascade concentrators, whose operational principle involves the absorption of optical radiation followed by its reemission at a longer wavelength and radiation concentration onto a highly efficient small-area photodetector. The absorption and re-emission spectra of each cascade layer depend on the characteristics of the material used. Сolloidal quantum dots are among the most promising materials for cascade layers due to their manufacturing technology, which provides for accurate control over the photoluminescence maximum position. It seems highly relevant to develop and to study photosensitive structures with cascade concentrators of various shapes based on CdS, CdSe/ZnS, and PbS colloidal quantum dots. Aim . To develop photosensitive structures with a wide-range sensitivity spectrum based on concentrators containing arrays of metal chalcogenide CQDs and to study their characteristics. Materials and methods . Cascade photosensitive structures were manufactured based on layers made of polymethyl methacrylate and layers of colloidal quantum dots embedded in a polystyrene matrix. Results . Three-layer concentrators were manufactured with different colloidal quantum dots in each concentrator layers. A 22 % increase in the output power was observed for a three-layer cascade structure based on different cascade layer materials compared to a similar structure using a single layer concentrator. Conclusion . The conducted studies showed an increase in the efficiency of photosensitive structures with a cascade concentrator based on colloidal quantum dots of various types (CdS, CdSe/ZnS, and PbS) in the cascade layers.

N2 - Sichtweiten in der Atmosphäre reichen von wenigen Metern im Nebel bis zu einigen hundert Kilometern bei extrem guten Fernsichtbedingungen. Die zugrundeliegende Physik geht vom Wahrnehmungskontrast aus. Dieser ändert sich mit der Entfernung entlang der Sichtlinie zwischen Objekt und Auge aufgrund von Lichtstreuung und Absorption an den Bestandteilen der Atmosphäre. Dazu kommt bei der Fernsicht die Refraktion, die es erlaubt, auch über den durch die Kugelform der Erde geometrisch bedingten Horizont hinaus zu sehen.

T1 - The potential of LLMs for coding with low-resource and domain-specific programming languages
N2 - This paper presents a study on the feasibility of using large language models (LLM) for coding with low-resource and domain-specific programming languages that typically lack the amount of data required for effective LLM processing techniques. This study focuses on the econometric scripting language named hansl of the open-source software gretl and employs a proprietary LLM based on GPT-3.5. Our findings suggest that LLMs can be a useful tool for writing, understanding, improving, and documenting gretl code, which includes generating descriptive docstrings for functions and providing precise explanations for abstract and poorly documented econometric code. While the LLM showcased promoting docstring-to-code translation capability, we also identify some limitations, such as its inability to improve certain sections of code and to write accurate unit tests. This study is a step towards leveraging the power of LLMs to facilitate software development in low-resource programming languages and ultimately to lower barriers to entry for their adoption.

JF - The International Journal on Advances in Software
N2 - Low code development platforms (LCDP) often promise an easy and fast way to include data processing and support into the otherwise non-digital process. This research explores how to measure the productivity of low code development to assess the effort needed for business users to respond to their need for support via these tools. We chose field experiments as a research method to evaluate the feasibility and derive the metrics for software development with LCDP by novices. The paper provides some insights on how these measures can be implemented in practice, how to support business unit developers to efficiently deliver productive results, and how to evaluate LCDP-based development processes.

N2 - Low Code Development Platforms (LCDP) often promise an easy and fast way to include data processing and support into the otherwise non-digital process. Nevertheless, it often remains unclear, besides anecdotal evidence, how business users are getting on with transformation of business requirements into the software. This research explores the potential low code development has for business users to address their needs for process support via software tools. The experiment was chosen as the research method to assess the feasibility of software development with LCDP by novices. The results point towards a dedicated LCDP implementation approach if the technology is to be implemented in the business context. Hence, the research provides suggestions on how Business Unit Developers (BUD) can be supported to efficiently deliver productive results and how to assess LCDP-based development process and points towards potential challenges of LCDP implementation.

T1 - Mobile Instant Messaging and User Interface Design -Different Age Groups, Different Requirements? A survey of Indonesian users
T2 - Konferenz: IARIA ICDS 2023, The Seventeenth International Conference on Digital Society; Venice, Italy
N2 - Instant Messaging (IM) is an increasingly popular form of communication in which two or more people exchange text-based multi-media messages in real time. However, as a result of aging, users have different needs and requirements towards the design of the communication application. This paper examines the preferences of users of different ages towards the User Interface (UI) design of Mobile Instant Massage (MIM) applications, i.e., instant message applications that can operate on smartphones. An online survey data about users' preferences towards the UI of this application type, limited to Indonesian users, was obtained. The results indicate that for some UI elements, both age groups showed the same preferences, while other requirements were significantly different. This paper aims to give a better understanding of the interface of the MIM application preferred by its users according to their age and thus inform application designers and product owners.

T1 - Climate justice and the Global South - The road to solving climate change
N2 - Climate will be decided in the global south Mankind is on a dangerous journey in the Anthropocene. Arriving at a good life for all within planetary boundaries is still possible. But at present, the journey is more likely to lead to an overheating of the Earth. Health and life would then be massively endangered for many living beings - including humans. A positive development is still possible, but it requires a global transformation of the economy and society. The prosperous states and companies are well advised, to respect the interests of the global south and future generations, and to use wisely the considerable financial resources in a cooperation of equals. This book • highlights past carbon emissions and their consequences, • reflects on the main drivers of future emissions, • discusses strategies like green growth, de-growth, • presents market-based instruments like carbon trading and carbon border adjustment and • emphasises the key role played by the emerging countries of the global south. It is not only a matter of justice but furthermore in the interest of the rich countries in the global north to contribute massively to financing a "green leapfrogging" of the global south into a carbon-free prosperity. Failing to achieve it will bring unspeakable losses and suffering to many people all over the planet.

T1 - Auf dem Weg zu mehr Klimagerechtigkeit Im Bündnis mit dem Globalen Süden Widerstände überwinden
N2 - Die Menschen sind im Anthropozän auf einer gefährlichen Reise. Das Ziel steht noch nicht fest. Die Ankunft in einem guten Leben für alle innerhalb planetarer Grenzen ist immer noch möglich. Aber zurzeit führt die Reise eher zu einer Überhitzung der Erde. Gesundheit und Leben wären dann für viele Lebewesen – auch für den Menschen – massiv gefährdet. Das Buch behandelt die Fragen: • Wie sind wir in diese Lage geraten? • In welcher Richtung können Auswege liegen? • Welche Hindernisse sind zu überwinden? Es werden Strategien abgewogen und einige überraschende Bündnispartner identifiziert. Geschickt gestaltete Märkte können helfen, die Erderwärmung aufzuhalten. Nur in einer gleicheren und gerechteren Welt könnten alle Menschen gut, aber bescheidener leben. Die Alternative dazu wäre eine übererhitzte, gefährliche Welt. Eine gute Entwicklung ist noch möglich. Sie erfordert eine globale Transformation von Wirtschaft und Gesellschaft. Die wohlhabenden Staaten sind gut beraten, die Interessen des „Globalen Südens“ und der künftigen Generationen zu respektieren – auch durch den klugen Einsatz erheblicher Finanzmittel und eine Kooperation auf Augenhöhe.

N2 - The fast-paced digitalization and automation make hard skills acquired by employees in their academic study programs outdated and irrelevant very fast. Hence, researchers and practitioners have recently demonstrated a growing interest in studying soft skills in various settings, including leadership, education, and training. Additionally, in times of digital transformation, businesses are promoting employee engagement evermore, particularly in the present context of crises and instability. The research intends to investigate this issue from the viewpoint of employee soft skills. We specifically look into the link between employees’ soft skills and workplace engagement. While doing our research in two different countries, we distinguish between commercial and non-commercial organizations as well as add an international perspective. Based on an acknowledged European skills framework, we focus our study on such soft skills as teamwork, communication, and conflict management and use recognized surveys to quantify them. We use a well-known Gallup methodology to evaluate employee engagement. Using correlation analysis, we investigate the impact of the three selected skills on employee engagement while considering the organization type and country, factors that may play an important role in the digital transformation of businesses and companies.

T1 - Importance of OSINT/SOCMINT for modern disaster management evaluation - Australia, Haiti, Japan
JF - Electronic Imaging
N2 - Open-source technologies (OSINT) and Social Media Intelligence (SOCMINT) are becoming increasingly popular with investigative and government agencies, intelligence services, media companies, and corporations. These OSINT and SOCMINT technologies use sophisticated techniques and special tools to efficiently analyze the continually growing sources of information. There is a great need for training and further education in the OSINT field worldwide. This report describes the importance of open source or social media intelligence for evaluating disaster management. It also gives an overview of the government work in Australia, Haiti, and Japan for disaster management using various OSINT tools and platforms. Thus, decision support for using OSINT and SOCMINT tools is given, and the necessary training needs for investigators can be better estimated.

T1 - Practical OSINT investigation - Similarity calculation using Reddit user profile data
JF - Electronic Imaging
N2 - This paper presents a practical Open Source Intelligence (OSINT) use case for user similarity measurements with the use of open profile data from the Reddit social network. This PoC work combines the open data from Reddit and the part of the state-of-the-art BERT model. Using the PRAW Python library, the project fetches comments and posts of users. Then these texts are converted into a feature vector - representation of all user posts and comments. The main idea here is to create a comparable user's pair similarity score based on their comments and posts. For example, if we fix one user and calculate scores of all mutual pairs with other users, we will produce a total order on the set of all mutual pairs with that user. This total order can be described as a degree of written similarity with this chosen user. A set of "similar" users for one particular user can be used to recommend to the user interesting for him people. The similarity score also has a "transitive property": if $user_1$ is "similar" to $user_2$ and $user_2$ is similar to $user_3$ then inner properties of our model guarantees that $user_1$ and $user_3$ are pretty "similar" too. In this way, this score can be used to cluster a set of users into sets of "similar" users. It could be used in some recommendation algorithms or tune already existing algorithms to consider a cluster's peculiarities. Also, we can extend our model and calculate feature vectors for subreddits. In that way, we can find similar to the user's subreddits and recommend them to him.

T1 - Practical OSINT investigation in Twitter utilizing AI-based aggressiveness analysis
JF - Electronic Imaging
N2 - Open-source intelligence is gaining popularity due to the rapid development of social networks. There is more and more information in the public domain. One of the most popular social networks is Twitter. It was chosen to analyze the dependence of changes in the number of likes, reposts, quotes and retweets on the aggressiveness of the post text for a separate profile, as this information can be important not only for the owner of the channel in the social network, but also for other studies that in some way influence user accounts and their behavior in the social network. Furthermore, this work includes a detailed analysis and evaluation of the Tweety library capabilities and situations in which it can be effectively applied. Lastly, this work includes the creation and description of a compiled neural network whose purpose is to predict changes in the number of likes, reposts, quotes, and retweets from the aggressiveness of the post text for a separate profile.

T1 - FINEconcepts - Wissenstransfer und Energiesystemoptimierung mithilfe des digitalen Zwillings
T2 - NWK, HS Harz, 2023
N2 - Climate change, but also geopolitical circumstances, are moving topics such as energy efficiency and renewable energies more and more into the focus of the population, economy , and politics. As a result, the will to optimize new and existing energy systems extends from private individuals to companies and even entire communities. This work describes the development and usage of a new software called FINEconcepts which creates a digital twin of an energy system. This virtual model can then be used to optimize the energy system based on annual costs, CO2 emissions or other relevant criteria such as self-sufficiency. Because all system components, which include renewable technologies as well, can be added as a building block with chosen but changeable parameters, the software allows the user to explore and awaken interest and understanding of technologies that were previously considered too costly, irrelevant, or unrealistic. Implemented projects in small and large companies as well as in residential areas did prove, that the usage of FINEconcepts leads not only to more efficient energy systems by increasing the use of renewable energy, but also increased knowledge and understanding in terms of energy. Besides economics, ecology and security, understanding is an equally important factor in achieving a sustainable energy supply.

T1 - Pressure evolution of electronic structure and magnetism in the layered van der Waals ferromagnet CrGeTe3
JF - Physical Review B
N2 - Layered van der Waals ferromagnets, which preserve their magnetic properties down to exfoliated monolayers, are fueling an abundance of fundamental research and nanoscale device demonstration. CrGeTe3 is a prime example of this class of materials. Its temperature-pressure phase diagram features an insulator-to-metal transition and a significant increase in ferromagnetic Curie-Weiss temperatures upon entering the metallic state. We use density functional theory to understand the magnetic exchange interactions in CrGeTe3 at ambient and elevated pressures. We calculate Heisenberg exchange couplings, which provide the correct ferromagnetic ground state and explain the experimentally observed pressure dependence of magnetism in CrGeTe3. Furthermore, we combine density functional theory with dynamical mean-field theory to investigate the effects of electronic correlations and the nature of the high-pressure metallic state in CrGeTe3.

T1 - Fast Protein and Metabolites (Nucleotides and Nucleosides) Liquid Chromatography Technique and Chemical Sensor for the Assessment of Fish and Meat Freshness
JF - Chemosensors
N2 - Fast protein and metabolite liquid chromatography (FPLMC) was introduced years ago to enable the easy separation of high-molecular compounds such as proteins from small molecules and the identification of the low-molecular substances. In this paper, the method is applied for the rapid evaluation of freshness and monitoring the aging of animal meat and fish. A novel chromatographic sensor was developed with a deep UV LED-based photometric detection unit (255–265 nm), an original flow cuvette and registration scheme; the processing of a chromatogram with the sensor takes approximately 15 min. Strict isochronism between the elution of ATP metabolites, mainly hypoxanthine (Hx) and inosine monophosphate (IMP), and the time of maturation of meat or fish, was discovered. A new freshness index H* = [Hx]/[IMP] was introduced, which is proportional to the instrumental delay time in the FPMLC chromatograms: the H* index < 0.5 indicates the presence of inosine monophosphate (IMP) and the high quality of the meat or fish. Reasonably strong correlations were revealed between data obtained by FPMLC and total volatile basic nitrogen TVB-N (for fish) or volatile fatty acids VFA (for meat) content. Moreover, putative nucleotide salvage and an increase in the concentration of IMP were observed in fish after heat treatment using the FPMLC sensor and NMR technique.

N2 - A unified understanding of terms and their applicability is essential for every scientific discipline: steganography is no exception. Being divided into several domains (for instance, text steganography, digital media steganography, and network steganography), it is crucial to provide a unified terminology as well as a taxonomy that is not limited to some specific applications or areas. A prime attempt towards a unified understanding of terms was conducted in 2015 with the introduction of a pattern-based taxonomy for network steganography. Six years later, in 2021, the first work towards a pattern-based taxonomy for steganography was proposed. However, this initial attempt still faced several shortcomings, e.g., the lack of patterns for several steganography domains (the work mainly focused on network steganography and covert channels), various terminology issues, and the need of providing a tutorial on how the taxonomy can be used during engineering and scientific tasks, including the paper-writing process.
As the consortium who published this initial 2021-study on steganography patterns, in this paper we present the first comprehensive pattern-based taxonomy tailored to fit all known domains of steganography, including smaller and emerging areas, such as filesystem steganography and cyber-physical systems steganography. Besides, to make our contribution more effective and promote the use of the taxonomy to advance research on steganography, we also provide a thorough tutorial on its utilization.

T1 - Ethical and Legal Analysis of Machine Learning Based Systems: A Scenario Analysis of a Food Recommender System
T2 - Recommender Systems: Legal and Ethical Issues
N2 - Laws are the reflection of the ethical and moral principles of the society. While the use of technology influences users’ behavior in a pace that is affected by the technology introduction to the market, legal activities can be driven by the society as the results of such interactions. This scenario analysis- based research focuses on a classic but fictional food recommender system and the ethical issues that might occur from its usage. The recommender system is taken here as an example of machine learning-based systems (MLS) that can often be found in the individual, business and administrative applications. The research compares the existing legal solutions, with the focus on the GDPR legislation, and the discovered ethical issues. The ethical analysis is led along the ALTAI principles suggested by the European Commission, the common good approach as well as the general principles constituted in human rights. While the GDPR-based analysis showed that this data- and privacy-based legislation addressed most of the identified ethical issues, questions related to the common good approach in the context of environment and mobility that arise due to the wide spectrum of the MLS usage require further legal discussion. The application of the two approaches shows that conducting the ethical and legal analysis is beneficial for both the designers of such MLS as well as the legal actors. The findings can enhance the design and functions of a user-facing MLS as well as influence or validate legal activities.

T1 - Operationalizing Ethics for Information Systems Design - A Tool for Ethical Software
T2 - Konferenz: Twenty-ninth Americas Conference on Information Systems (AMCIS), Panama, 2023
N2 - Propagation of information technology in the increasingly diverse domains, raises question concerning moral implications. While the number of ethical principles in the IT design is growing, they do not necessarily apply to specific products, which means developers and e.g. purchasing agent need to contextualize them for each specific IT product. This paper describes an actionable artifact that allows assessment of ethical non-functional requirements of an information system through operationalization of ethical values, Ethical Software Assessment Tool (ESAT). It is based on a survey of values that are currently considered in research and practice as well as in legal initiatives in IT context. The ethical approach and principles operationalized in ESAT are presented and discussed.

T1 - Analyse der Trends und Alternativen zur Online-Präsenz als Kommunikationskanal von kleinen und mittleren Unternehmen durch den Einsatz von Plattformen
BT - Ergebnisse einer Studie durch das Institut für Betriebliche Integration und Digitalisierung (IBID) am Fachbereich Wirtschaft der Technischen Hochschule Brandenburg
T2 - Schriften des Instituts für Betriebliche Integration und Digitalisierung (IBID)
N2 - Die Digitalisierung ist eine der Herausforderungen der heutigen Zeit. Einhergehend mit der Zunahme der Nutzung des Internets in vielen Lebensbereichen steigt auch die Wichtigkeit für Unternehmen, einen repräsentativen Auftritt zu etablieren. Für kleine und mittlere Unternehmen bedeutet das Betreiben und Pflegen einer Onlinepräsenz oftmals einen hohen finanziellen und zeitlichen Aufwand. Ziel des vorliegenden Arbeitspapiers ist es, kleinen und mittleren Unternehmen eine Alternative zu herkömmlichen Content Management Systemen darzulegen und sie bei der Entscheidungsfindung zu unterstützen. Zur Beantwortung der Forschungsfragen wurde der methodische Ansatz einer Literatur- und Internetrecherche verwendet. Aus der Analyse konnten drei Online Business Plattformen identifiziert, sowie deren Vor- und Nachteile gegenüber Content Management Systemen dargestellt werden. Anschließend wurden Kriterien definiert und Empfehlungen dargelegt, welche kleine und mittlere Unternehmen im Entscheidungsprozess unterstützen sollen. Letztlich wurden die Einrichtung sowie die wichtigsten Funktionen einer Plattform dargestellt. Die Ergebnisse zeigen, dass die Nutzung einer Onlineplattform für lokal begrenze Unternehmen mit geringen Anforderungen an die Funktionalität und hoher Kostensensibilität eine sinnvolle Alternative ist. Abschließend wurde anhand des realen Fallbeispiels „Google My Business“ (seit 2022: „Google Business Profile“) auf die Funktionen sowie Vorteile und Möglichkeiten einer solchen Plattform eingegangen.
N2 - Digitalization is one of the big challenges of our time. Along with the increased online life, the importance for companies to establish a representative online presence is growing as well. Especially for small and medium size companies, the operation and maintenance of an online presence means a high effort in terms of time and financial investment. The aim of this study is to provide an alternative to common content management systems for small medium size companies. In addition, they should be supported in the decision making process. To answer the research questions the methodical approach of a literature and internet research was used. From the analysis, three online business platforms were identified and their advantages and disadvantages compared to content management systems were presented. Subsequently, criteria were defined and recommendations were presented, which should support small and medium-sized enterprises in the decision-making process. Finally, the setup as well as the most important functions of a platform were presented. The results show that the use of an online platform is a sensible alternative for locally limited companies with low functionality requirements and high cost sensitivity. Finally, the functions as well as advantages and possibilities of such a platform were discussed on the basis of the real case study "Google My Business" (since 2022: "Google Business Profile")

T1 - Machine-Learning Verfahren für eine nachhaltige Letzte-Meile-Logistik
N2 - Dieser Beitrag entwickelt ein Konzept zur praktischen Umsetzung eines Machine- Learning Verfahrens zum Lösen von Vehicle Routing Problemen im Kontext einer nachhaltigen “Letzte-Meile”-Logistik, welches durch einen Prototyp umgesetzt und getestet wurde. Der Prototyp basiert auf dem “Reinforcement Learning”-System und verwendet als Algorithmus “REINFORCE mit Baseline”. In einer Vergleichsanalyse wurde der Prototyp mit dem bekannten Vertreter Google-OR, anhand von zwei Anwendungsszenarien, verglichen. Der Prototyp überzeugt dabei in der Laufzeit und dem Automatismus. Es konnte festgestellt werden, dass eine Verwendung von Lernenden-Systemen für das Vehicle Routing Problem sich bei nur bei einem größeren Stoppvolumen und einer erweiterten IT-Infrastruktur empfiehlt.

T1 - Scan to Learn: A Lightweight Approach for Informal Mobile Micro-Learning at the Workplace
T2 - Konferenz: IARIA The Fifteenth International Conference on Mobile, Hybrid, and On-line Learning; Venice (Italy)
N2 - Informal learning at the workplace is a crucial ingredient in updating and upskilling today's workforce, but in many jobs, informal learning opportunities are scarce. Bite-sized learning via mobile devices (Mobile Micro-Learning, MML) can be a powerful means to enhance informal work-related learning also in such learning-deprived fields. Based on good practices of recent MML implementations, a lightweight approach is developed. It involves an instructional blueprint and an open-source, low-threshold technology for MML, and meets the specific needs of workers in learning-deprived fields. The main idea is a scan-to-learn system where Quick Response (QR) codes are attached to physical objects in the work environment. Workers can scan the QR codes to learn and are directed to short, interactive learning nuggets. For evaluation, a proof-of-concept is provided.

T1 - The structure of disintegrating defect clusters in smectic C freely suspended films
JF - Soft Matter
N2 - Disclinations or disclination clusters in smectic C freely suspended films with topological charges larger than one are unstable. They disintegrate, preferably in a spatially symmetric fashion, into single defects with individual charges of +1, which is the smallest positive topological charge allowed in polar vector fields. While the opposite process of defect annihilation is well-defined by the initial defect positions, disintegration starts from a singular state and the following scenario including the emerging regular defect patterns must be selected by specific mechanisms. We analyze experimental data and compare them with a simple model where the defect clusters adiabatically pass quasi-equilibrium solutions in one-constant approximation. It is found that the defects arrange in geometrical patterns that correspond very closely to superimposed singular defect solutions, without additional director distortions. The patterns expand by affine transformations where all distances between individual defects scale with the same time-dependent scaling factor proportional to the square-root of time.

T1 - Coalescence of biphasic droplets embedded in free standing smectic A films
JF - Soft Matter
N2 - We investigate micrometer-sized flat droplets consisting of an isotropic core surrounded by a nematic rim in freely suspended smectic A liquid-crystal films. In contrast to purely isotropic droplets which are characterized by a sharp edge and no long-range interactions, the nematic fringe introduces a continuous film thickness change resulting in long-range mutual attraction of droplets. The coalescence scenario is divided in two phases. The first one consists in the fusion of the nematic regions. The second phase involves the dissolution of a thin nematic film between the two isotropic cores. The latter has many similarities with the rupture of thin liquid films between droplets coalescing in an immiscible viscous liquid.
Coalescence of biphasic droplets in free-standing smectic films is controlled in part by the rupture of a thin nematic membrane separating the isotropic droplet cores.

T1 - Puzzle away the Puzzledness: Action-Design Study of an Educational Escape Room for Intervention in SMEs’ Perception towards ICT Adoption
T2 - Konferenz: 57th Hawaii International Conference on System Sciences (HICSS); Honolulu, HI, USA
N2 - Digital transformation initiatives in small and medium-sized enterprises (SME) are often hampered by individual practitioners' perceptions of information and communication technology (ICT). This research employs an educational escape room (ER) game for an intervention towards informed decision-making on ICT adoption in SMEs. ER design and implementation are elaborated and consequently tested with SME practitioners, all embedded in an action-design study based on a qualitative research methodology. The result highlights a trade-off between creating immersive game experiences and achieving learning objectives. Still, the outcome implies an impact on players' perception of ICT integrated in the ER. The findings contribute to the emerging field of serious games for learning and shed light on the potential of game-based interventions for SMEs.

T1 - What is Digital about Digital Innovation? An Ontological Discussion of Digitality
T2 - Konferenz: 29th Americas Conference on Information Systems
N2 - "Digital" is a popular adjective for concepts related to electronic, computerized or networked processes in current research and practice. From an ontological-theoretical perspective, the prevalence of digital things triggers the question, how Digitality itself could be conceptualized. This article studies the ontology of Digitality and consequently discusses Digital Innovation (DI) from a new perspective. First, literature on Digitality is analyzed. Based on the findings, an ontological conceptual framework of Digitality (OCFD) is proposed. It describes four layers of Digitality: physical foundations, virtuality, digital culture and world, and digital metaphysics. From a human perspective, requirements to grasp and embody Digitality are highlighted, as well as the expansion of reality. Finally, Digitality is discussed as a paradigm of DI and exemplary digital phenomena are projected onto the OCFD. This paper contributes to DI research and practice through theory-building towards a better understanding of ontological characteristics and practical implications of Digitality in DI.

T2 - Konferenz: Perspectives in Business Informatics Research
22nd International Conference on Business Informatics Research, BIR 2023, Ascoli Piceno, Italy, September 13–15, 2023, Proceedings
N2 - This article presents a research outline on the use of microlearning applications to develop digital competencies in Small and Medium-sized Enter-prises (SMEs). The digital transformation of businesses has become essential for their survival, and SMEs need to develop digital competencies (DC) to remain competitive in the market. Microlearning (ML), a form of learning that involves small, bite-sized learning modules, has been gaining popularity in recent years as a way to efficiently and effectively develop skills. Through a semi-systematic literature review approach, our study examines prevalent knowledge in the area of ML and DC and discusses interrelations. As a result, we propose a research roadmap consisting of six research questions targeting four dimensions of ML for DC development in SMEs: 1) context, 2) formats, 3) reward system, and 4) complexity level.

T1 - Small Businesses Participating in Digital Platform Ecosystems - A Descriptive Literature Review
T2 - Digital Transformation. PLAIS EuroSymposium 2023. Lecture Notes in Business Information Processing
N2 - The emergence of digital multi-sided platforms has disrupted day-to-day business in many industries. Nowadays, many small businesses participate in digital platform (DP) ecosystems and act as value creators or complementors. Investigating the small business perspective does not have a rich tradition in platform research yet. In response, this paper presents a systematic literature review (SLR) analyzing the thematic points of focus and highlighting new avenues for information systems and small business research. We find that objectives related to digital transformation, digital strategy- and business model-development, and DP adoption are fundamental topics in the conjunction of small business and DP ecosystems. Based on the findings, an agenda for future research is developed, including propositions for practice-oriented and human-centered approaches fostering sustilience, innovation capabilities and digital leadership competencies in small businesses facing DP ecosystem participation.

T1 - Attack Detection for Medical Cyber-Physical Systems – A Systematic Literature Review
JF - IEEE Access
N2 - The threat situation due to cyber attacks in hospitals is emerging and patient life is at risk. One significant source of potential vulnerabilities is medical cyber-physical systems (MCPS). Detecting intrusions in this environment faces challenges different from other domains, mainly due to the heterogeneity of devices, the diversity of connectivity types, and the variety of terminology. To summarize existing results, we conducted a structured literature review (SLR) following the guidelines of Kitchenham et al. for SLRs in software engineering. We developed six research questions regarding detection approach, detection location, included features, adversarial focus, utilized datasets, and intrusion prevention. We identified that most researchers focused on an anomaly-based detection approach at the network layer. The primary focus was on the detection of malicious insiders. While several researchers used publicly available datasets for training and testing their algorithms, the lack of suitable datasets resulted in the development of testbeds consisting of various medical devices. Based on the results, we formulated five future research topics. First, the special conditions of hospital networks, the MCPS deployed within them, and the contrasts to other IT and OT environments should be examined. Thereupon, MCPS-specific datasets should be created that allow researchers to address the health domain’s unique requirements and possibilities. At the same time, endeavors aimed at standardization in this area should be supported and expanded. Moreover, the use of medical context for attack detection should be further explored. Last but not least, efforts for MCPS-tailored intrusion prevention should be intensified. This way, the emerging threat landscape can be addressed, IT security in hospitals can be improved, and patient health can be protected.

T1 - Mathematische Remodellierung zur Erforschung der exakten Semantik einfacher konventioneller Notationssysteme
T2 - Notation. Schnittstelle zwischen Komposition, Interpretation und Analyse. 19. Jahreskongress der Gesellschaft für Musiktheorie Zürich 2019 (GMTH Proceedings 2019)
N2 - Das Projekt semPart – Semantik der Partitur versucht, durch Übertragung von Methoden der Informatik auf die musikalische Notation exakte Aussagen über deren Semantik zu erzielen. Dies geschieht durch Remodellierung, also durch das Erstellen kleiner mathematischer Modelle, die jeweils das historisch-kulturell bestimmte Dekodieren von isolierten Parameter-Schichten eines Notates nachbilden. Erstes wichtiges Ergebnis ist, dass es in keinem Bereich jemals eine einzige ›richtige‹ Definition von Syntax und Semantik geben kann, sondern einen Katalog von vielfältigen theoretisch möglichen und in der Praxis auch angetroffenen Varianten. Diese sind durch ihre Remodellierung exakt identifizier- und benennbar; ihre Gesamtheit bildet ein Raster, durch das Notationsstile und -werkzeuge beschreib- und vergleichbar werden. Dieses Raster und die Remodelle sind besonders politisch wichtig, zur Förderung einer öffentlichen Diskussion von Notationssystemen und ihren Eigenschaften, da zunehmend die Arbeitsweise von digitalen Werkzeugen die notationelle Praxis zu überformen und zu filtrieren droht.
The project semPart – Semantics of the Musical Score tries to clarify the semantics of musical notation by applying methods from informatics. This is done by remodelling, i. e., constructing small mathematical models that mimic the mentally and culturally determined processes taking place when decoding isolated parameters in musical notation. The first important result is that there can never be one single ‘correct’ definition of semantics in any area but rather a catalogue of many theoretically possible variants encountered in practice. Through their remodelling, these can be precisely identified and named; their totality constitutes a classification grid applicable to styles, corpora, single scores and digital tools such as editors or encoding standards. This grid and the remodels are of particular political importance in promoting a public discussion on notation systems and their characteristics, given that the increasing use of digital processing systems threatens to over-shape and narrow down notational practice.

T1 - IN-FDM-BB Werkstattbericht: W 1.2.2 Auswertung Bedarfserhebung mit daraus folgenden Aktivitäten
N2 - Forschungsdatenmanagement (FDM) gewinnt an den Hochschulen in Brandenburg eine immer größere Bedeutung. Für den Aufbau und die Institutionalisierung eines nachhaltigen FDM an den brandenburgischen Hochschulen ist eine möglichst genaue Ermittlung des aktuellen Kenntnisstandes der Forschenden und deren Bedarfe bezüglich des Umgangs mit Forschungsdaten erforderlich. Hierzu diente die Bedarfserhebung, die im Rahmen des vom BMBF und dem MWFK geförderten Projekts IN-FDM-BB durchgeführt wurde. Beteiligt an der brandenburgweiten Umfrage waren alle acht staatlichen forschenden Hochschulen: vier Universitäten (die Brandenburgische Technische Universität Cottbus – Senftenberg (BTU), die Filmuniversität Babelsberg KONRAD WOLF (FB), die Europa-Universität Viadrina Frankfurt (Oder) (EUV) und die Universität Potsdam (UP)) und vier Hochschulen für Angewandte Wissenschaften (die Fachhochschule Potsdam (FHP), die Hochschule für nachhaltige Entwicklung Eberswalde (HNEE), die Technische Hochschule Brandenburg (THB) und die Technische Hochschule Wildau (THW)). Die Hochschulen unterscheiden sich erheblich in ihrer Größe und fachlichen Ausrichtung. So hat die UP deutlich über 20.000 Studierende und über 1.900 Professor*innen und akademische Mitarbeiter*innen, die FB hingegen, weniger als 1.000 Studierende und ca. 140 Professor*innen und akademische Mitarbeiter*innen. Landesweit sind fast alle Fachdisziplinen vertreten, jedoch mit unterschiedlichen Schwerpunkten je Hochschule.
Das Ziel der Bedarfserhebung war, den Kenntnisstand bezüglich des professionellen Umgangs mit Forschungsdaten der Forschenden an den einzelnen Hochschulen zu ermitteln, FDM-Bedarfe zu erkennen und daraus mögliche FDM-Aktivitäten für die jeweilige Hochschule abzuleiten. Die Bedarfserhebung richtete sich daher in erster Linie an die Forschenden der jeweiligen Hochschule.

T1 - The Impact of prototyping on the survival chances of digital early-stage startups: Findings and insights from explorative expert interviews
T2 - Proceedings of the 18th European Conference on Innovation and Entrepreneurship, ECIE 2023
N2 - The products of digital entrepreneurs are highly innovative, and their business models contribute to the prosperity and further development of the economy and society. However, studies indicate that most of all startups fail, particularly during the early stages of their business journey Prototyping as part of Lean Startup or Business Model Testing approaches, can assist digital early-stage startups in navigating uncertainty and achieving successful product launches. However, these methods are applied very individually and there is little empirical research on best practices. We therefore conducted 65 explorative expert interviews and asked successful startups about their prototyping practices. Our results include learnings on the prototyping process and the testing format, the role of the founding team during prototyping practices, the customer focus and the role of networks. Our study adds important details to theory and practice of the innovation and prototyping processes of digital early-stage startups. Our results offer actionable advice and guidance to any current and potential entrepreneur, but especially to first-time founders and less experienced executives in early stage-startups. Additionally, our contribution enhances the theoretical understanding of the Lean Startup approach and prototyping practices.

T1 - Immersive Experience for Sustainable Tourism - The Potential of a Community-Based 3D Scanning Database App on the Example of South East Asia
T2 - 2023 International Electronics Symposium (IES), Denpasar, Indonesia, 2023
N2 - Sustainable tourism focuses on minimizing the negative impact of tourism on the environment and cultural heritage sites, allowing future generations to enjoy tourism. Immersive experiences can support sustainable tourism further by allowing people to visit tourist places without physically being there. This helps to reduce negative impacts such as overcrowding, pollution, and damage to natural and cultural resources. An app that encourages people to create 3D scans of places they visit has the potential to contribute to virtual tourism. With modern technology, a wider range of people can contribute to a community-based 3D scan collection by sharing their photos and scans. This app can help to gain a more comprehensive and accurate understanding of various locations around the world and create a variety of virtual tours. This paper specifically focuses on Southeast Asia and provides guidelines for creating content and material for the app.

Der Werkstattbericht Konzept für Informationsmaterialien und FDM-Webseite (W 1.1.1) ist der erste Bericht, den alle acht am Projekt IN-FDM-BB beteiligen Hochschulen vorlegen und der konkret die lokale Institutionalisierung von FDM an den Einrichtungen behandelt.

T1 - Light pollution from illuminated bridges as a potential barrier for migrating fish-Linking measurements with a proposal for a conceptual model
JF - Basic and Applied Ecology
N2 - Illuminated bridges have become important assets to navigable aquatic systems. However, if artificial light at night (ALAN) from illuminated bridges reaches aquatic habitats, such as rivers, it can threaten the river's natural heterogeneity and alter the behavioural responses of migratory fish. Here, via a pilot study, we quantified levels of ALAN at illuminated bridges that cross a river and, propose a conceptual model to estimate its potential implications on two migrating fish species with contrasting life histories. Night-time light measurements on the river Spree in Berlin were performed continuously along a transect and in detail at seven illuminated bridges. Photometric data of the pilot study showed rapidly increased and decreased light levels at several illuminated bridges from which we derived several model illumination scenarios. These illumination scenarios and their potential effect on migrating Atlantic salmon smolts (Salmo salar) and European silver eel (Anguilla anguilla) are presented as a conceptual model, considering illuminated bridges as behavioural barriers to fish migration. ALAN's adverse effects on freshwater habitats must be better researched, understood, managed, and properly communicated to develop future sustainable lighting practices and policies that preserve riverscapes and their biodiversity.
