A recommendation for suitable technologies for an indoor farming framework
No full textFacing food insecurity and overuse of resources due to effects of climate change, humanity needs to find new ways to secure food production and produce close to consumers. Vertical farming, where plants are grown in vertical arrays inside buildings with help of Information and Communication Technology (ICT) components, could contribute to solving this issue. Such systems integrate heterogeneous devices on different computing layers and acquire a lot of data to monitor and optimize the production process. We created an indoor testing unit in which growing conditions can be monitored and controlled to optimize growth of microgreens. This setup includes an Indoor Farming Support as a Service (IFSaaS) prototype that provides safe and secure monitoring and controlling, as well as self-adaption of an indoor farming system. In this article we provide information about the combination of most suitable technologies.Forschung Burgenlan
Content Curation im E-Learning
No full textLoseblatt Ausgabe (87. Erg.-Lfg.)Lerninhalte, die nach dem Gießkannenprinzip auf alle MitarbeiterInnen verteilt werden, sind selten effizient. Für jeden Lernenden eigene Inhalte zu erstellen, stellt aber einen (zu) großen Aufwand da. Dies ist in vielen Fällen
allerdings gar nicht erforderlich, da es bereits bestehende Inhalte (News-Artikel, Lernvideos, Whitepapers, Podcast-Interviews etc.) gibt, die man nutzen und ins E-Learning integrieren kann. Content Curation ist eine
Möglichkeit, dies umzusetzen.
Von Content Curation spricht man, wenn man eine „Kollektion“ an Inhalten zu einem bestimmten Thema für eine definierte Zielgruppe kuratiert. Man greift dabei auf bestehende Inhalte zurück – ähnlich wie ein(e)
KuratorIn in einem Museum die Ausstellungsstücke nicht selbst herstellt. Ziel ist es, für die einzelnen Lernenden relevante Inhalte zu kuratieren, die ihnen einen Mehrwert liefern – und damit die Informationsüberlastung zu reduzieren.Informationstechnologie und Informationsmanagemen
Modeling of solar radiation transmission through triple glazing based only on on-site measurements
No full textA model is developed which can calculate the irradiance behind a glazed façade, based on measured incident solar radiation. Data from a real office building is used to establish and test the model. Onsite irradiance measurements on both sides of the facades are exploited to calibrate the model. The main parameters are the average diffuse transmittance and a correlation for the direct transmittance, as a function of the incidence angle. Correction of the measurements, including the frame reflection, are taken into account. Hence, the model contributes to the solar heat flux identification, in the perspective of model predictive control application
Pricing Models for German Wine: Hedonic Regression vs. Machine Learning
No full textThis article examines whether there are different hedonic price models for different German wines by grape variety, and identifies influential factors that focus on weather variables and direct and indirect quality measures for wine prices. A log linear regression model is first applied only for Riesling, and then machine learning is used to find hedonic price models for Riesling, Silvaner, Pinot Blanc, and Pinot Noir. Machine learning exhibits slightly greater explanatory power, suggests adding additional variables, and allows for a more detailed interpretation of results. Gault&Millau points are shown to have a significant positive impact on German wine prices. The log linear approach suggests a huge effect of different quality categories on the wine prices for Riesling with the highest price premiums for Auslese and “Beerenauslese/Trockenbeerenauslese/Eiswein (Batbaice),” while the machine learning model shows, that additionally the alcohol level has a positive effect on wines in the quality categories “QbA,” “Kabinett,” and “Spätlese,” and a mostly negative one in the categories “Auslese” and “Batbaice.” Weather variables exert different affects per grape variety, but all grape varieties have problems coping with rising maximum temperatures in the winter and with rising minimum and maximum temperatures in the harvest season.Informationstechnologie und Informationsmanagemen
