    QuaMath – A Large-scale Implementation Program to improve Mathematics Education
    (Hannover : Technische Informationsbibliothek, 2024-06-11) Hallemann, Svea
    This Mini-Review introduces the QuaMath program (“Developing Quality in Mathematics classrooms and teacher professional development”). The national 10-year program aims to develop the quality of mathematics instruction and teacher professional development in collaboration with the federal states. QuaMath is conducted within the framework of the DZLM (Deutsches Zentrum für Lehrkräftebildung Mathematik (German Center for Mathematics Teacher Education, a network of 12 German universities collaborated with the IPN Leibniz-Institute for Science and Mathematics Education)). Working with teachers and practitioners, the DZLM develops, implements, and researches effective training and support programs in mathematics for teachers and early childhood educators. I address the special role of the 400 facilitators in the implementation and success of the QuaMath program. They themselves receive intense training from the Consortium of Mathematics Education Professors (DZLM).

    Effects of Open Access. Literature study on empirical research 2010–2021
    (Hannover : Technische Informationsbibliothek (TIB), 2024) Hopf, David; Dellmann, Sarah; Hauschke, Christian; Tullney, Marco
    Open access — the free availability of scholarly publications — intuitively offers many benefits. At the same time, some academics, university administrators, publishers, and political decision-makers express reservations. Many empirical studies on the effects of open access have been published in the last decade. This report provides an overview of the state of research from 2010 to 2021. The empirical results on the effects of open access help to determine the advantages and disadvantages of open access and serve as a knowledge base for academics, publishers, research funding and research performing institutions, and policy makers. This overview of current findings can inform decisions about open access and publishing strategies. In addition, this report identifies aspects of the impact of open access that are potentially highly relevant but have not yet been sufficiently studied.

    SLL–SMART LOGISTICS FOR LOCALS : „Schlussbericht des Projekts Smart Logistics for Locals – SLL“
    (2024) Hempel, Harald; Jaudszus, Anke; Haußen, Tina
    Ziel des Forschungsprojekts "SLL – SMART LOGISTICS for LOCALS" war die Schaffung eines digitalen Marktplatzes für lokale Anbieter und lokale Kunden, inklusive der logistischen Strukturen für einen Lieferservice nach Hause. Damit sollte einerseits kleinen lokalen Einzelhändlern und Gastronomen der Einstieg ins Online-Geschäft erleichtert werden und andererseits der lokale Logistikpartner in der Erprobung einer nachhaltigen Mehrzwecklogistik mit entsprechenden Kostensenkungspotentialen unterstützt werden. Übergeordnete Ziele des Vorhabens waren die Stärkung der Wettbewerbsposition regionaler Anbieter, die Verbesserung der regionalen Wertschöpfungs- und Vermarktungsstrukturen, sowie die Unterstützung des Aufbaus einer nachhaltigen Regionallogistik. Schlussendlich sollte eine Lösung geschaffen werden, die auch auf andere Regionen übertragbar ist.

    Composite forming simulation for non-crimp fabrics based on generalized continuum approaches – AMECOMP : Abschlussbericht / Final project report (DFG 431354059 / ANR-19-CE06-0031)
    (Hannover : Technische Informationsbibliothek, 2024-05) Schäfer, Bastian; Kärger, Luise; Naouar, Naim; Zheng, Ruochen; Schäfer, Bastian; Kärger, Luise; Naouar, Naim; Zheng, Ruochen; Boisse, Philippe; Colmars, Julien; Platzer, Auriane
    Continuously carbon fiber reinforced composites are increasingly used for structural applications in various fields of engineering due to their excellent weight-specific mechanical properties. Non-crimp-fabrics (NCF) provide the highest lightweight potential as reinforcement for the composite due to their straight fibers, compared to woven fabrics with undulated fibers. NCFs are made of one (UD-NCF), two (Biax-NCF) or more directions of fibers linked together with a polymer stitching in specific patterns. The deformation behavior of NCFs is challenging due to the interaction between the fibers and the stitching, which also results in a higher susceptibility to forming effects such as roving slippage, fiber waviness and gapping compared to woven fabrics. The aim of the AMECOMP project was to improve the understanding of the forming behavior of NCFs and to develop suitable simulation models to broaden the range of potential applications. Mesoscopic models that accurately describe the architecture of the NCF were developed for virtual material characterization and detailed analysis of forming defects in critical areas. Macroscopic models that describe the relevant deformation mechanisms of NCF in a homogenized way were developed for efficient analysis of large components and multi-layer stacks.
