    Adjungierten-basierte Synthese und Bestimmung optimaler Treiberfunktionen von Lautsprechern mit komplexer Richtcharakteristik (2021)
    Details
    Publication Date: 2022-01-19
    Description: Die Bestimmung optimaler Treiberfunktionen von Lautsprechern mit frequenzabhängiger Richtcharakteristik ist ein schlecht gestelltes Optimierungsproblem. Zu dessen Lösung haben die Autoren in vorangegangenen Beiträgen eine adjungierten-basierte Methode zur Optimierung von Lautsprecher-Arrays im Zeitbereich vorgestellt [5, 6, 8]. Diese ermöglicht unter anderem die Berücksichtigung von Berandungen und Umgebungseffekten wie Wind, war jedoch bisher auf monopol-artige Quellen beschränkt. Um diese Einschränkung zu beheben, haben die Autoren einen adjungierten-basierten Zeitbereichsansatz mit Finiten-Differenzen (FDTD) zur Synthese komplexer synthetischer Schallquellen durch diskrete, gitter-basierte Monopole vorgestellt [4, 9]. In diesem Beitrag demonstrieren die Autoren die entsprechende Modellierung eines realen Zweiwege-Monitors (A). Zudem wird gezeigt, wie sich die Vielzahl der zur Synthese verwendeten Monopole in eine Lautsprecher-Treiberfunktion überführen lassen (B).

    Urheberrechtsreform 2021. Neue Chancen für das kulturelle Erbe (2021)
    Details
    Publication Date: 2022-02-14
    Description: Im Juni 2021 fand die jüngste Urheberrechtsreform statt. Sie bietet neue Chancen für das kulturelle Erbe, sei es in den Archiven und Bibliotheken sozialer Bewegungen, kleinen und großen Museen oder staatlichen Archiven und Bibliotheken. Denn die Novelle beinhaltet neue gesetzliche Erlaubnisse, die insbesondere die Online-Stellung von Archivmaterialien (“nicht verfügbare Werke”) und den Schutz der Gemeinfreiheit betreffen. Das vorliegende Bulletin geht komprimiert auf diese Neuerungen ein und erklärt, was sich in Zukunft ändern wird. Darauf aufbauend wird Mitte 2022 eine ausführliche und aktualisierte Publikation zur Rechteklärung erscheinen. Diese Vorveröffentlichung soll erste drängende Fragen klären. Herausgeber:innen sind das Digitale Deutsche Frauenarchiv (DDF) und das Forschungs- und Kompetenzzentrum Digitalisierung Berlin (digiS), die bereits unabhängig voneinander Handreichungen zu rechtlichen Aspekten der Digitalisierung veröffentlichten.

    Fully automated Assessment of Knee Alignment from Full-Leg X-Rays employing a "YOLOv4 And Resnet Landmark regression Algorithm" (YARLA): Data from the Osteoarthritis Initiative (2021)
    Details
    Publication Date: 2022-07-19
    Description: We present a method for the quantification of knee alignment from full-leg X-Rays. A state-of-the-art object detector, YOLOv4, was trained to locate regions of interests (ROIs) in full-leg X-Ray images for the hip joint, the knee, and the ankle. Residual neural networks (ResNets) were trained to regress landmark coordinates for each ROI.Based on the detected landmarks the knee alignment, i.e., the hip-knee-ankle (HKA) angle, was computed. The accuracy of landmark detection was evaluated by a comparison to manually placed landmarks for 360 legs in 180 X-Rays. The accuracy of HKA angle computations was assessed on the basis of 2,943 X-Rays. Results of YARLA were compared to the results of two independent image reading studies(Cooke; Duryea) both publicly accessible via the Osteoarthritis Initiative. The agreement was evaluated using Spearman's Rho, and weighted kappa as well as regarding the correspondence of the class assignment (varus/neutral/valgus). The average difference between YARLA and manually placed landmarks was less than 2.0+- 1.5 mm for all structures (hip, knee, ankle). The average mismatch between HKA angle determinations of Cooke and Duryea was 0.09 +- 0.63°; YARLA resulted in a mismatch of 0.10 +- 0.74° compared to Cooke and of 0.18 +- 0.64° compared to Duryea. Cooke and Duryea agreed almost perfectly with respect to a weighted kappa value of 0.86, and showed an excellent reliability as measured by a Spearman's Rho value of 0.99. Similar values were achieved by YARLA, i.e., a weighted kappa value of0.83 and 0.87 and a Spearman's Rho value of 0.98 and 0.99 to Cooke and Duryea,respectively. Cooke and Duryea agreed in 92% of all class assignments and YARLA did so in 90% against Cooke and 92% against Duryea. In conclusion, YARLA achieved results comparable to those of human experts and thus provides a basis for an automated assessment of knee alignment in full-leg X-Rays.
