The technique is intended to detect sensor intrinsic pre-processing steps as well as manually applied filters. We have exemplary chosen 6 pre-processing filters with different parameter settings. The concept utilizes 29 image features which are supposed to allow for a reliable model creation during supervised learning. The evaluation of the trained models indicates average accuracies between 82.50 and 94.53%. The investigation of image data from 8 sensors leads to the detection of credible pre-processing filters. Those results adumbrate that our method might be suitable to prove the authenticity of the data origin and the integrity of image data based on the detected preprocessing techniques. The preliminary evaluation for manually applied filters yields recognition accuracies between 39.09% (14 classes) and 53.33% (7 classes).

A liquid-filled defect is introduced that turns into a resonant cavity. Similar to the well-known resonant sensors sensitivity can be increased with higher operating frequencies. We introduce a Sandwiched Phononic Crystal (SPC), which applies a resonant cavity located between two stacked layers on top of a SAW device. Key challenges are coupling of surface acoustic wave into the liquid cavities and avoiding scattering of the guided waves into the bulk of the sensor chip.

Sensors based on this principle feature a band gap covering the typical input span of the measurand as well as a narrow transmission peak within the band gap where the frequency of maximum transmission is governed by the measurand. This approach has been applied for determination of volumetric properties of liquids (Lucklum et al. in Sens Actuators B Chem 171–172:271–277, 2012; Oseev et al. in Sens Actuators B Chem 189:208–212, 2013; Lucklum and Li in Meas Sci Technol 20(12):124014, 2009) and has demonstrated attractive sensitivity. One way to improve sensitivity requires higher probing frequencies in the range of 100 MHz and above. In this range surface acoustic wave (SAW) devices are an established basis for sensors. We have performed first tests towards a PnC microsensors (Lucklum et al. in Towards a SAW based phononic crystal sensor platform. In: 2013 Joint European frequency and time forum and international frequency control symposium (EFTF/IFC), pp 69–72, 2013). The respective feature size of the PnC SAW sensor has dimensions in the range of 10 µm and below. Whereas those dimensions are state of the art for common MEMS materials, etching of holes and cavities in piezoelectric materials that have an aspect ratio diameter/depth is still challenging. In this contribution we describe an improved technological process able to realize considerably deep and uniform holes in a SAW substrate.

The metal-oxide coatings morphology is the result of melt drop transfer, heat treatment, and oxidation. The study establishes the influence of technological regimes of alloying and oxidation on morphological heterogeneity of biocompatible layered metal-oxide system Ti-Ta-(Ti,Ta)xOy. It was found that during electro-spark alloying the concentration of tantalum on the titanium surface ranges from 0.1 to 3.2 at.%. Morphology of the deposited splats is represented by uniformly grown crystals of titanium and tantalum oxides, which increase from nano- to submicron size.

By now, the community is very active and has reported diverse detection approaches. So far, the evaluations are mostly performed on images without post-processing. Face images stored within electronic machine readable documents (eMRTD) are ICAO-passport-scaled to a resolution of 413x531 and a JPG or JP2 lesize of 15 kilobytes. This paper introduces a face morphing detection concept with 3 modules (ICAO-aligned pre- processing module, feature extraction module and classi cation module), tailored for such images on eMRTD. In this work we exemplary design and evaluate two feature spaces for the feature extraction module, a frequency domain and a spatial domain feature space. Our evaluation will compare both feature spaces and is carried out with 66,229 passport-scaled images (64,363 morphed face images and 1,866 authentic face images) which are completly independent from training and include all images provided for the IHMMSEC'19 special session: "Media Forensics - Fake or Real?". Furthermore, we investigate the in uence of di erent morph gen- eration pipelines to the detection accuracies of the concept and we analyse the impact of neutral and smiling genuine faces to the morph detector performance. The evaluation determines a detection rate of 86.0% for passport-scaled morphed images with a false alarm rate of 4.4% for genuine images for the spatial domain feature space.

The attack aims at creating artificially weakened templates which can be successfully matched against multiple persons. If successful, the attack has an immense impact on many biometric authentication scenarios including the application of electronic machine-readable travel document (eMRTD) at automated border control gates. We extend the StirTrace framework for benchmarking FMF attacks by adding five issues: a novel three-fold definition for the quality of morphed images, a novel FMF realisation (combined morphing), a post-processing operation to simulate the digital image format used in eMRTD (passport scaling 15 kB), an automated face recognition system (VGG face descriptor) as additional means for biometric quality assessment and two feature spaces for FMF detection (keypoint features and fusion of keypoint and Benford features) as additional means for forensic quality assessment. We show that the impact of StirTrace post-processing operations on the biometric quality of morphed face images is negligible except for two noise operators and passport scaling 15 kB, the impact on the forensic quality depends on the type of post-processing, and the new FMF realisation outperforms the previously considered ones.

It is endeavored that the created morphs cannot be recognized as such with the naked eye and a reference automatic face recognition (AFR) system produces high similarity scores while matching a morph against faces of persons who participated in morphing. Automatic generation of morphs allows for creating abundant experimental data, which is essential (i) for evaluating the performance of AFR systems to reject morphs and (ii) for training forensic systems to detect morphs. Our first experiment shows that human performance to distinguish between morphed and genuine face images is close to random guessing. In our second experiment, the reference AFR system has verified 11.78% of morphs against any of genuine images at the decision threshold of 1% false acceptance rate. These results indicate that facial morphing is a serious threat to access control systems aided by AFR and establish the need for morph detection approaches. Our third experiment shows that the distribution of Benford features extracted from quantized DCT coefficients of JPEG-compressed morphs is substantially different from that of genuine images enabling the automatic detection of morphs.

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.

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.

But this requires a certain amount of restraint on the part of the designers of the respective setting and at the same time seems to require a full disclosure of the underlying theoretical and aesthetic concepts to the participants, if the participants are really to be taken seriously and given the means to actually be able to become creative themselves in an understandable way within the given context. In this paper, the consequences of such a demand are first discussed theoretically. Finally, for the concept developed by the author, ”Every human being can compose on the basis of natural numbers”, an attempt is made in this specific case to determine in what form such a concept could be passed on in order to meet the above criteria.

This thesis aims to develop a technical representation of the MITRE ATT&CK matrix to enable faster and more effective responses to cyber attacks. Based on a analysis of common cyber attack models, such as the Diamnond Model of Intrusion Analysis and the Lockheed Martin Cyber Kill Chain, the MITRE ATT&CK matrix is used to develop an extended Kill Chain model. In this new model, MITRE tactics are grouped into five sequential attack phases, allowing for a clearer differentiation between actions taken during an attack. Aditionally, one ongoing group of MITRE tactics was identified. Building on this model, two graph-based representations are developed: a simple graph structure and a hierarchical, tree-shaped graph of MITRE tactics and techniques. The following discussion addresses the practical application of the new model, as well as potential further developments, such as integrating AI to analyse and predict existing and potential attack patterns.

Um diese Aufgabe zu vereinfachen werden Monitoring-Systeme eingesetzt. Diese sammeln und verarbeiten Daten, um den Status des IT-Systems zu ermitteln. Zu diesen Monitoring-Systemen zählt Wazuh, welches in der Lage ist, die "Integrität" und "Vertraulichkeit" unter Zuhilfenahme von Agenten zu überwachen. Damit deckt Wazuh lediglich zwei der drei Schutzziele der IT-Sicherheit ab. Aus diesem Grund wird in dieser Bachelorarbeit untersucht, auf welche Art und Weise sich das SIEM und XDR System um Heartbeat Monitoring erweitern lässt. Dadurch wird Wazuh befähigt das dritte Schutzziel der IT-Sicherheit, die Verfügbarkeit, zu überwachen. Zu diesem Zweck wird eine Erweiterung der Wazuh-Implementierung um den Heartbeat Daemon des Elastic Stacks durchgeführt. Die Implementierung soll in der Lage sein, die Daten des Heartbeat Daemons zu empfangen, zu speichern, darzustellen und Benachrichtigungen auszulösen, sobald sich der Status von überwachten Systemkomponenten ändert. Um die Funktionalität dieses Proof of Concepts zu überprüfen wird Heartbeat Monitoring ebenfalls in einem Vergleichssystem umgesetzt. Dabei handelt es sich um die native Umgebung des Daemons, den Elastic Stack. Die Funktionalität des Elastic Stacks konnte auf unterschiedlichen Wegen reproduziert werden. Dies erfolgt zum einen durch die direkte Verarbeitung der Heartbeat-Ausgabe durch Wazuh. Alternativ besteht die Möglichkeit, die Heartbeat-Daten direkt in Wazuhs Datenbank zu schreiben. In Abhängigkeit der Version des Heartbeat-Daemons ist die Verwendung von Logstash als Middleware erforderlich. Das Darstellen der Daten ist für beide Methoden in Wazuhs Weboberfläche möglich. Das Erweitern von Wazuh um Heartbeat Monitoring ermöglicht der Software die Abdeckung der relevantesten Schutzziele der IT-Sicherheit. Es wird gezeigt, welche Methoden zur Erweiterung der Open-Source-Software angewendet werden können.

Diese Arbeit untersucht Data-Augmentation-Methoden im Bereich von Zeitreihen, welche dieses Problem adressieren. Dabei werden insbesondere Machine-Learning-Verfahren (Autoencoder, Variational Autoencoder, TimeGAN) untersucht und mit algorithmischen Ansätzen (Jittering, Time Warping) verglichen. Die Methoden werden anhand der Kriterien Ähnlichkeit, Diversität und Nützlichkeit bewertet. Die Ergebnisse zeigen, dass algorithmische Verfahren konsistent bessere Ergebnisse liefern als Machine-Learning-Methoden. Zudem wird festgestellt, dass der Einsatz generativer Machine-Learning-Verfahren nur dann sinnvoll ist, wenn das generative Modell weniger komplex ist als das Modell, welches die synthetischen Daten letztlich verwenden soll. N2 - In the domain of time series, there is a lack of high-quality data, which can negatively affect the performance of deep learning models. This thesis examines data augmentation methods in the field of time series that address this issue. In particular, machine learning approaches (Autoencoders, Variational Autoencoders, TimeGAN) are investigated and compared with algorithmic techniques (Jittering, Time Warping). The methods are evaluated using discriminative-, visual- and predictive evaluation. The results show that algorithmic approaches consistently yield better outcomes than machine learning methods. Furthermore, it is noted that the use of generative machine learning techniques is only meaningful when the generative model is less complex than the model that will ultimately utilize the synthetic data.

Im Kontext der E-Commerce-Plattform der Telefónica Germany GmbH & Co. OHG stellt sich die Frage, ob die neu eingeführten Virtual-Threads dazu verwendet werden können, den aktuellen Softwareentwicklungsprozess des Unternehmens zu optimieren. Zu diesem Zweck werden Proof-of-Concept-Anwendungen entwickelt, die auf den Webframeworks Spring MVC und Spring WebFlux basieren. Diese Anwendungen werden anschließend einem Stresstest unterzogen, um die Leistungsunterschiede der Threading-Modelle zu analysieren. Die Ergebnisse der Untersuchung legen nahe, dass die Verwendung von Virtual- Threads im Vergleich zu Platform-Threads in einer asynchronen Spring MVC- Architektur zu einer Reduktion der durchschnittlichen Antwortzeit um etwa 20 % und zu einer Steigerung des Durchsatzes um nahezu 20 % führt. Des Weiteren konnte eine Reduktion der CPU- und RAM-Auslastung bei maximaler Last um 11 % bzw. 13 % festgestellt werden. Obwohl die Spring WebFlux- Architektur unter Verwendung von Platform-Threads und eines Netty-Servers in den meisten Testmetriken bessere Ergebnisse erzielte, sind die Resultate der asynchronen Spring MVC-Architektur mit Virtual-Threads vielversprechend. Eine Implementierung dieser Technologie könnte demnach eine deutliche Verbesserung des aktuellen Softwareentwicklungsprozesses im Unternehmen bewirken. N2 - The bachelor thesis analyzes the performance and resource utilization of platform and virtual threads in Java 21. In the context of the e-commerce platform of Telefónica Germany GmbH & Co. OHG, the question arises as to whether the newly introduced virtual threads can be used to optimize the company's current software development process. To this end, proof-of-concept applications based on the Spring MVC and Spring WebFlux web frameworks are being developed. These applications are then subjected to a stress test to analyze the performance differences between the threading models. The results of the investigation suggest that the use of virtual threads compared to platform threads in an asynchronous Spring MVC architecture leads to a reduction in the average response time of around 20% and an increase in throughput of almost 20%. Furthermore, a reduction in CPU and RAM utilization at maximum load of 11% and 13%, respectively, was observed. Although the Spring WebFlux architecture using platform threads and a Netty server achieved better results in most test metrics, the results of the asynchronous Spring MVC architecture with virtual threads are promising. Implementing this technology could, therefore, significantly improve the company's current software development process.

Durch den Einsatz von Datenscraping-Techniken auf sozialen Medien (X) in Kombination mit einer Python-basierten Verarbeitungspipeline und Elasticsearch zur Speicherung und Abfrage von Daten wird ein robustes System zur Analyse und Visualisierung bedrohungsrelevanter Informationen entwickelt. Das System integriert Natural Language Processing (NLP) Techniken, wie das Stanford CoreNLP-Framework und den Stucco Entity Extractor, um gesammelte Daten mit Cybersicherheitsentitäten anzureichern. Zudem werden maschinelle Lernmodelle, insbesondere Satztransformatoren, verwendet, um Texte einzubetten und die Kosinus-Ähnlichkeit zwischen potenziellen Bedrohungen und Warnmeldungen zu berechnen. Damit wird gezeigt, dass die Korrelation externer Datenquellen mit Threat Intelligence die Präzision von Alarmen erheblich verbessert und sicherheitsrelevante Einblicke für Analysten liefert. Das finale System bietet eine skalierbare und effiziente Datenverarbeitung sowie Echtzeit-Visualisierungen durch Elasticsearch und Kibana-Dashboards zur Unterstützung der Entscheidungsfindung in der Cybersicherheit.

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.

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.

Although quite efficient for our daily life, many technological applications require sensor properties beyond the characteristics of our eyes. A major limitation regarding microscopic objects is spatial resolution, which is overcome by microscopes. Time resolution can be dealt with using either time-lapse or high-speed cameras. Finally, eyes only detect visible radiation within the wavelength range from about 380 nm to 780 nm. Changing the detected spectral range of electromagnetic radiation can dramatically enhance our vision. Shorter wavelengths such as x-rays are valuable tools for medical imaging, while ultraviolet (UV) imaging is used for forensics. Longer-wavelength thermal radiation used for imaging is often defined within spectral ranges, characterized by the photoelectric detector materials used and the respective atmospheric windows.

T1 - Fundamentals of Thermal Imaging T2 - Thermal Cameras in Science Education N2 - The quantitative explanation of thermal radiation in 1900 by Max Planck started a development, which today has resulted in modern infrared technologies with thermal imaging cameras. The present work briefly describes the fundamentals of infrared imaging, based on the fact, that every object at a temperature T > 0 K emits thermal radiation. Its amount is only governed by temperature and the material quantity emissivity. Factors that define types and properties of commercial IR cameras, such as temperature range in nature and industry, the atmospheric windows for IR radiation as well as available optics and detectors are discussed. A short summary of typical specifications of IR cameras and interpretation of recorded images is given.

T1 - Infrared Cameras as Smartphone Accessory: Qualitative Visualization or Quantitative Measurement? T2 - Thermal Cameras in Science Education N2 - Recently, infrared cameras have become available as smartphone accessories. Being less expensive than regular infrared cameras they are readily affordable and widespread use in the future is expected. Available commercial models are compared and examples for meaningful use and interpretation of respective qualitative images is given. The respective arguments also directly apply to other commonly used low-grade IR cameras with similar pixel resolution and frame rates. It is assumed that users know about the typical problems due to, e.g., thermal reflections. Rather than discussing those, focus is on the danger of wrong interpretations, in particular with regard to the low frame rate, the often implemented image processing within the cameras, the imposed restrictions on necessary input parameters, and the extremely limited spatial resolution and respective errors in potential quantitative analyses.

ED - Bhat, Rajeev T1 - Physics of the Electromagnetic Spectrum T2 - Electromagnetic Technologies in Food Science N2 - Electromagnetic (EM) waves, spanning about 15 orders of magnitude of wavelength (or frequency or energy) from radio waves via microwaves, infrared radiation, visible light, ultraviolet radiation, and X-rays to the highly energetic γ-rays, are utilized in food processing. In order to explain all uses of these waves in the food industry, the chapter begins with a general discussion of properties of waves and their description with wavelength frequency, speed of propagation, and also energy transport. Using visible light as starting point, electromagnetic waves in other wavelength regimes are discussed. The interaction of EM radiation with matter reveals that the wave description alone is insufficient to explain all observed phenomena. Understanding the attenuation of EM radiation in matter requires knowledge of the particle properties of electromagnetic waves, most easily summarized by the concept of photons which carry energy as well as momentum. This wave–particle duality does apply not only to EM waves, i.e. photons, but also to the particles which build up matter, in particular electrons, which also need to be described as waves. This leads to respective quantum mechanical explanations of the microscopic structure of matter in the form of atoms, molecules, and nuclei. Knowledge of their structure is a prerequisite to understand, first, the generation of EM radiation and, second, also its interaction with matter. As a result, it will become obvious that there are mostly three different usages of EM radiation in the food industry: preserving, characterizing, and heating.

The study employs a rapid literature review methodology to analyze the utilization of ALT in workplace learning. The findings indicate that the use of ALT is predominantly concentrated in the education, health and medical sectors, with limited implementation in other sectors. Moreover, in smaller organizations, in non-technical sectors and among white-collar workers, there are fewer opportunities for technology-enhanced learning. The study highlights the need for more inclusive and comprehensive research to address the digital divide in workplace learning, taking into consideration practice-based evidence and exploring the themes covered by training. Furthermore, the paper proposes an investigation into the complexity and resource intensity of implementing ALT to enhance technology-based learning in all workplaces. In general, this research establishes the basis for comprehending and bridging the digital learning divide in the workplace.

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.

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.

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].

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.

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.

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.

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.

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.

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.

Jahrhundert dar und bietet darüber hinaus eine am Beispiel demonstrierte, systematische Analyse der Verflechtung von Misswirtschaft mit Medien, Staat und Gesellschaft. Die Phönix Lebensversicherung, mit Sitz in Wien und Kunden in 22 Ländern, wurde im Jahr 1936 zahlungsunfähig. Sie hatte riesige Verluste aufgetürmt, Bilanzen gefälscht und Schlüsselpersonen hofiert. Ihr Sturz drohte eine europaweite Finanzkrise auszulösen und wurde mit diktatorischen Maßnahmen aufgefangen. Das Buch schildert die wirtschaftliche wie politische Rolle des Versicherers vor 1918, während der Weimarer Republik und ab 1933.
