The absolute microsphere-assisted Raman signal from a single graphene layer measured in air is more than a factor of two higher than that obtained with a high numerical aperture objective. Results from Mie's theory are used to benchmark numerical simulations and an analytical model to describe the isolated microsphere focusing properties.

There are three main reasons for this development. First, on the one hand, it is the immersive character of this media form, and, on the other hand, the development of recording and presentation technology has made significant progress in terms of resolution and quality. Third, after a decade of dynamic rising, the MICE Industry focuses on a disruptive change for more digital-based solutions. 360-degree panoramas are particularly widespread in VR and AR technology. However, despite the high immersive potential, these forms of presentation have the disadvantage that the users are isolated and have no social contact during the performance. Therefore, efforts have been made to project 360-degree content in specially equipped rooms or planetariums to enable a shared experience for the audience. One application area for 360-degree panoramas and films is conference rooms in hotels, conference centers, and any other venues that create an immersive environment for their clients to stimulate creativity. This work aims to overview the various application scenarios and usability possibilities for such conference rooms. In particular, we consider applications in construction, control, tourism, medicine, art exhibition, architecture, music performance, education, partying, organizing and carrying out events, and video conferencing. These applications and use scenarios were successfully tested, implemented, and evaluated in the 360-degree conference room "Dortmund" in the Hotel Park Soltau in Soltau, Germany.

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.

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 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.

Seven weeks after the fracture of the fibula and six weeks after surgery the measurement of the gait of the subject has been started.

The intensity of the weekly tests has been increased in dependence on the healing progress. Both scenarios-walking on the floor and on the treadmill-were included in the experiments to obtain comparable data sets. Beside of the investigation of the healing process the paper is focused on symmetry/asymmetry properties of the gait. The results indicate that asymmetry is not only an essential property of pathologic gait but it is present in normal gait too, especially if short distances are evaluated. They may be caused by the influence of a dominant/injured leg, of the first/last steps, the natural variance of the gait or the daily fitness of the subject.

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.

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.

Dies ist das einzig Verl{\"a}ssliche f{\"u}r Wirtschaft und Gesellschaft. Zum einen z{\"a}hlt die kreative Zerst{\"o}rung 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) M{\"a}rkte 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 Ver{\"a}nderungen durch die Finanzkrise zeigen. Einige Akteure und Standorte bleiben mit ihrem jeweiligen Profil und Potenzial (weiterhin) produktiv widerstandsf{\"a}hig.

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.

Zu diesem Zweck werden Proof-of-Concept-Anwendungen entwickelt, die auf den Webframeworks Spring MVC und Spring WebFlux basieren.

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.

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.}, language = {en} } @misc{OPUS4-3250, title = {Jahrbuch 2023/2024 der Absolventinnen und Absolventen}, editor = {Wilms, Andreas}, publisher = {Technische Hochschule Brandenburg}, address = {Brandenburg an der Havel}, organization = {Technische Hochschule Brandenburg}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-32507}, pages = {92}, year = {2024}, language = {de} } @misc{OPUS4-3254, title = {Forschungs- und Transferbericht der Technischen Hochschule Brandenburg 2022/23}, editor = {Wilms, Andreas and Hirsch, S{\"o}ren}, publisher = {Technische Hochschule Brandenburg}, address = {Brandenburg an der Havel}, organization = {Technische Hochschule Brandenburg}, issn = {1861-3462}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-32541}, pages = {98}, year = {2024}, language = {de} } @inproceedings{FroschLindauerZuidhof2024, author = {Frosch, Katharina and Lindauer, Friederike and Zuidhof, Niek}, title = {Exploring the Digital Divide in Workplace Learning: A Rapid Review}, series = {ICDS 2024, The Eighteenth International Conference on Digital Society, Barcelona, Spain}, booktitle = {ICDS 2024, The Eighteenth International Conference on Digital Society, Barcelona, Spain}, publisher = {IARIA}, pages = {1 -- 6}, year = {2024}, abstract = {This article examines the digital learning divide in workplace learning, with an emphasis on the disparity in the distribution of advanced learning technologies (ALT) across different types of workplaces.
