Approach for the identification of requirements on the design of AI-supported work systems (in problem-based projects)
No full textTo successfully develop and introduce concrete artificial intelligence (AI) solutions in operational practice, a comprehensive process model is being tested in the WIRKsam joint project. It is based on a methodical approach that integrates human, technical and organisational aspects and involves employees in the process. The chapter focuses on the procedure for identifying requirements for a work system that is implementing AI in problem-driven projects and for selecting appropriate AI methods. This means that the use case has already been narrowed down at the beginning of the project and must be completely defined in the following. Initially, the existing preliminary work is presented. Based on this, an overview of all procedural steps and methods is given. All methods are presented in detail and good practice approaches are shown. Finally, a reflection of the developed procedure based on the application in nine companies is given
Entwicklung eines Erscheinungsbildes für das Centre und die Route Charlemagne
No full textDas Centre Charlemagne ist das Heimat- und Geschichtsmuseum der Stadt Aachen. Die Ausstellung begleitet die Geschichte der Stadt von der Zeit Karl des Großen bin hin zur Neuzeit. Die gleichnamige Kulturroute, Route Charlemagne, führt Besucher:innen dabei auf die acht bedeutendsten Stationen der Stadt hinsichtlich ihrer Geschichte und des Wirkens Karl des Großen. Das neue Erscheinungsbild bietet eine Interpretation in die Moderne. Durch eine hochwertige, aber auffallende Gestaltung trifft sie die Balance zwischen jung und alt. Die App Charlemagne, ein digitaler Museums- und Routenführer greift diese Balance erneut auf und bringt die Wissensvermittlung damit auf ein neues Level. Ziel dieser Arbeit ist es, das Museumserlebnis attraktiver und präsenter zu gestalten und damit die klassische Zielgruppe zu erweitern
1105 MINDCONDUCTOR : Neue HMI im Feld der digitalen Musikproduktion
No full textDas Musizieren am PC hat viele Hürden im Prozess der Musikproduktion eingerissen. Gleichzeitig geht dabei viel Detail, natürliche Ungenauigkeit verloren, die von den Hörenden vermisst wird. Projektziel war es, den Musikproduktionsprozess am Computer menschlicher zu gestalten, in dem technische Hürden und Redundanzen bestehender Controller-Lösungen neu gedacht werden. Dies soll durch die Einbindung neuer Bedienmöglichkeiten wie Eyetracking, Handtracking und Sprachsteuerung in einen All-in-One Produktionscontroller zum Einspielen und Bearbeiten von Musik erreicht werden. Diese natürlichen Interaktionsmöglichkeiten zusammen mit einer höheren Flexibilität bei der Belegung von Bedienelementen sorgt für einen reibungslosen Workflow, bei dem die Technik völlig in den Hintergrund treten kann. “MINDCONDUCTOR” leitet musikalische Ideen widerstandslos an dein digitales Orchester weiter

No full textAssessment of aeroacoustic optimisation schemes for a tilt-propeller application in hover and cruise
No full textBalancing propeller optimisation between cruise and hover conditions is a key challenge in eco-friendly aircraft design. This paper presents a novel multidisciplinary propeller optimisation approach, integrating blade element momentum theory and acoustic models. Three propeller design strategies are systematically evaluated in multidisciplinary propeller optimisation, considering aerodynamic efficiency and noise emissions. The design strategies and the optimisation scheme are assessed within the paper. A serial optimisation scheme improves the overall optimisation result and reduces the optimisation time significantly. In the serial approach, the design space is reduced stepwise. In the initial step, linear chord and parabolic twist distributions are sufficient for defining global propeller parameters like blade number and diameter. In contrast, detailed blade shape optimisation requires a parametric blade description. The findings are utilized to develop a novel optimisation scheme, reducing computational effort and enabling innovative air mobility solutions to be designed
Magnetic biosensing with magnetic nanoparticles: Simulative approach to predict signal intensity in frequency mixing magnetic detection
No full textMagnetic nanoparticles (MNP) are investigated with great interest for biomedical applications in diagnostics (e.g. imaging: magnetic particle imaging (MPI)), therapeutics (e.g. hyperthermia: magnetic fluid hyperthermia (MFH)) and multi-purpose biosensing (e.g. magnetic immunoassays (MIA)). What all of these applications have in common is that they are based on the unique magnetic relaxation mechanisms of MNP in an alternating magnetic field (AMF). While MFH and MPI are currently the most prominent examples of biomedical applications, here we present results on the relatively new biosensing application of frequency mixing magnetic detection (FMMD) from a simulation perspective. In general, we ask how the key parameters of MNP (core size and magnetic anisotropy) affect the FMMD signal: by varying the core size, we investigate the effect of the magnetic volume per MNP; and by changing the effective magnetic anisotropy, we study the MNPs’ flexibility to leave its preferred magnetization direction. From this, we predict the most effective combination of MNP core size and magnetic anisotropy for maximum signal generation
EEM spectroscopy characterization of humic substances of biomedical importance
No full textHumic substances possess distinctive chemical features enabling their use in many advanced applications, including biomedical fields. No chemicals in nature have the same combination of specific chemical and biological properties as humic substances. Traditional medicine and modern research have demonstrated that humic substances from different sources possess immunomodulatory and anti-inflammatory properties, which makes them suitable for the prevention and treatment of chronic dermatoses, allergic rhinitis, atopic dermatitis, and other conditions characterized by inflammatory and allergic responses [1-4]. The use of humic compounds as agentswith antifungal and antiviral properties shows great potential [5-7]
