Telemetry-Based Operational Dataset for Condition Monitoring of Digitally Configurable DC/DC Converters
(2025-12) Andreas Federl (https://orcid.org/0000-0002-4381-2653); Markus Böhmisch; Valentin Sagstetter; Gerhard Fischerauer; Robert Bösnecker
This dataset contains time-resolved telemetry data acquired from a digitally configurable DC/DC converter supplying a mechatronic demonstrator system with dynamic load behavior. The data were recorded under controlled laboratory conditions and are intended for research on telemetry-based condition monitoring, embedded machine learning (TinyML), and sensorless load classification.
In addition to the raw telemetry signals, the dataset includes features derived from the telemetry data. These features are directly applicable to telemetry-based condition monitoring, embedded machine learning (TinyML), and sensorless load classification tasks.
Digital Teaching and Learning & Didactics of Computer Science
Digitales Lehren und Lernen
Lehrkräfte aller Fächer brauchen Kompetenzen zur Auswahl und zum Einsatz digitaler Medien im Unterricht, um diese gewinnbringend und mit Mehrwert für den Lehr-Lern-Prozess einsetzen zu können. Daneben steht das Thema "Digitalisierung" in allen Unterrichtsfächern auch selbst im Fokus. Um dem Thema gerecht zu werden, benötigen alle Lehrkräfte medienbezogene informatische, mediendidaktische und medienbildende bzw. medienerzieherische Kompetenzen. Wir entwickeln, erproben und evaluieren dazu Konzepte für die Lerhramtsausbildung und den Unterricht.
Didaktik der Informatik
Informatikunterricht hat für die Bildung in einer digitalisierten, vernetzten Welt eine besondere Bedeutung. Zeitüberdauernde informatische Kompetenzen helfen auch in der sich schnell verändernden Welt den Überblick zu bewahren und neue Möglichkeiten einzuschätzen und bewerten zu können. Informatische Bildung hilft einen eigenen Kompass zur Navigation in der digital vernetzten Welt zu entwickeln und hat dabei auch die gesellschaftlichen Einflüsse im Blick. Wir vermitteln angehenden Informatiklehrkräften die fachdidaktischen und unterrichtspraktischen Grundlagen, um Schülerinnen und Schülern informatische Kompetenzen vermitteln zu können.
Relative and absolute abundances of bacteria and fungi in soil at the Achenkirch soil warming experiment
(2026-01-09) Borken, Werner
Long-term soil warming may alter microbial community structure and functioning in forest soils, thereby affecting carbon and nutrient cycling processes. We examined the effects of >14 years of soil warming (+4°C during snow-free seasons) on the fungal biomass marker ergosterol, and on fungal and bacterial communities in a spruce dominated mountain forest in the Austrian Alps. Soil warming decreased ergosterol, and the ergosterol-to-microbial biomass carbon (MBC) ratio at 0-10 and 10-20 cm soil depth, with a stronger decline in ergosterol, indicating a higher sensitivity of fungi than bacteria to long-term warming. Warming also shifted the fungal community at both soil depths, favoring Boletus luridus, an ectomycorrhizal (ECM) fungus, which emerged as the dominant OTU in warmed plots. Its abundance was positively associated with fine root biomass, root tip density, and soil respiration in warmed plots but negatively with ergosterol and MBC in control plots at 010 cm depth. The dominance of ECM over saprotrophic fungi (SAP) under warming at topsoil likely resulted from increased fine root production and enhanced competition for substrates and nutrients. Bacterial abundance and community composition remained mostly unaffected at both depths, likely due to their greater resilience to elevated temperatures and their high taxonomic diversity. Our findings therefore suggest that long-term warming primarily affects fungal community composition and functional traits, thereby enhancing the contribution of ECM with fine roots to the carbon cycle in the calcareous forest soil.

TEM data for the first observation of quenched Davemaoite to Ambient Conditions: its Electron Diffraction Pattern
(2025-09-11) Miyajima, Nobuyoshi
Calcium-rich silicate perovskite, davemaoite is often completely amorphized at ambient pressure, because the perovskite structure containing large element is unstable at 1 bar. However, we obtained for the first time an electron diffraction pattern of davemaoite in a transmission electron microscope. To understand why the unstable crystalline davemaoite lasted so long in the microscope, we investigate the textures with surrounding minerals using the electron-beam imaging and analyze the ambient volume from the diffraction patterns to understand the survival mechanisms. We find that the preservation of the crystalline state is most likely due to a static pressure generated by volume expansion of the surrounding amorphous glass transformed from the precursor denser crystalline state. The mechanism had not been demonstrated experimentally in a sub-micrometer microscopy before, even in the recovery of high-pressure minerals in shocked meteorites. Understanding this mechanism is important because the other high-pressure minerals at a small domain might survive at much lower pressure than the stability field at high pressure even though they are usually unquenchable. Further high-pressure minerals under a static stress can be discovered at ambient conditions by fine electron microscopy.
