The experimentally measured chemical and thermal structure of the spray flame is critically needed as a validation target for simulations of the synthesis of nanoparticles in these spray flames. This paper presents an experimental study of the chemical and thermal structure of the flame produced by the SpraySyn burner. The spatial distribution of the main species is obtained by microprobe sampling in combination with orthogonal time-of-flight mass spectrometry. The temperature distribution is obtained by a micro-thermocouple technique. The presented species and temperature data are discussed in the context of their experimental uncertainties and the plausibility of the flame structure.}},

In contrast to previous methods, the curved tetrahedral elements are guaranteed to be free of degeneracies and inversions while conforming exactly to prescribed piecewise polynomial surfaces, such as domain boundaries or material interfaces. Arbitrary polynomial order is supported. Algorithmically, the polynomial input surfaces are first covered by a single layer of carefully constructed curved elements using a recursive refinement procedure that provably avoids degeneracies and inversions. These tetrahedral elements are designed such that the remaining space is bounded piecewise linearly. In this way, our method effectively reduces the curved meshing problem to the classical problem of linear mesh generation (for the remaining space).</jats:p>}},

            Volumetric mapping is a ubiquitous and difficult problem in Geometry Processing and has been the subject of research in numerous and various directions. While several methods show encouraging results, the field still lacks a general approach with guarantees regarding map bijectivity. Through this work, we aim at opening the door to a new family of methods by providing a novel framework based on the concept of
            <jats:italic>progressive expansion.</jats:italic>
            Starting from an initial map of a tetrahedral mesh whose image may contain degeneracies but no inversions, we incrementally adjust vertex images to expand degenerate elements. By restricting movement to so-called
            <jats:italic>expansion cones</jats:italic>
            , it is done in such a way that the number of degenerate elements decreases in a strictly monotonic manner, without ever introducing any inversion. Adaptive local refinement of the mesh is performed to facilitate this process. We describe a prototype algorithm in the realm of this framework for the computation of maps from ball-topology tetrahedral meshes to convex or star-shaped domains. This algorithm is evaluated and compared to state-of-the-art methods, demonstrating its benefits in terms of bijectivity. We also discuss the associated cost in terms of sometimes significant mesh refinement to obtain the necessary degrees of freedom required for establishing a valid mapping. Our conclusions include that while this algorithm is only of limited immediate practical utility due to efficiency concerns, the general framework has the potential to inspire a range of novel methods improving on the efficiency aspect.

  abstract     = {{<jats:p>We present a set of operators to perform modifications, in particular collapses and splits, in volumetric cell complexes which are discretely embedded in a background mesh. Topological integrity and geometric embedding validity are carefully maintained. We apply these operators strategically to volumetric block decompositions, so-called T-meshes or base complexes, in the context of hexahedral mesh generation. This allows circumventing the expensive and unreliable global volumetric remapping step in the versatile meshing pipeline based on 3D integer-grid maps. In essence, we reduce this step to simpler local cube mapping problems, for which reliable solutions are available. As a consequence, the robustness of the mesh generation process is increased, especially when targeting coarse or block-structured hexahedral meshes. We furthermore extend this pipeline to support feature alignment constraints, and systematically respect these throughout, enabling the generation of meshes that align to points, curves, and surfaces of special interest, whether on the boundary or in the interior of the domain.</jats:p>}},

This provides benefits over alternative definitions on the basis of vertices, edges, or faces. Additional interface layers enable support for feature data associated with such mesh entities in input and output as well.

Eine Möglichkeit liegt dabei in der Entwicklung theoretisch fundierter und praxisorientierter digitalisierungsbezogener Ressourcen, die für diese Zwecke genutzt werden können. Um solche Ressourcen zu entwickeln, erscheint der Ansatz der phasenübergreifenden Zusammenarbeit in Communities of Practice (CoPs) der Lehrkräftebildung vielversprechend, da hier die Expertise aller Phasen genutzt werden kann. Bisherige Forschungsergebnisse zu Gelingensbedingungen der Zusammenarbeit lassen auf Faktoren wie Zielorientierung, Aufgabenbewältigung, Zusammenhalt oder Verantwortungsübernahme schließen, beziehen sich jedoch überwiegend auf Teams im Allgemeinen oder CoPs aus dem Wirtschaftskontext. Bisher unerforscht sind damit Gelingensbedingungen für die phasenübergreifende Zusammenarbeit in der Lehrkräftebildung, weshalb der vorliegende Beitrag diese Thematik untersucht. Zur Bearbeitung dieses Forschungsdesiderates werden quantitative und qualitative Daten aus dem COMeIN-Verbundvorhaben (Communities of Practice für eine innovative Lehrkräftebildung in NRW) herangezogen. Mittels einer multiplen Regressionsanalyse wurde die Aufgabenbewältigung in den CoPs als zentraler Prädiktor für positiv wahrgenommene phasenübergreifende Zusammenarbeit identifiziert. Die qualitative Inhaltsanalyse verdeutlicht zudem u.a. die hohe Relevanz der Beachtung der unterschiedlichen Systemlogiken der lehrkräfte-bildenden Phasen. Die Ergebnisse können dazu beitragen, die Zusammenarbeit der lehrkräftebildenden Phasen in CoPs zu verbessern, um so gesellschaftliche Transformationen in der Lehrkräftebildung adäquat mitzugestalten.}},

We performed our systematic study on the example of the 3D Manufacturing Format (3MF), which offers a large variety of features that could lead to critical attacks. Based on 3MF’s features, we systematized three attack goals: Data Exfiltration (dex), Denial of Service, and UI Spoofing (uis). We achieve these goals by exploiting the complexity of 3MF, which is based on the Open Packaging Conventions (OPC) format and uses XML to define 3D models. In total, our analysis led to 352 tests. To create and run these tests automatically, we implemented an open-source tool named 3MF Analyzer (tool), which helped us evaluate 20 applications.}},
