Sharing and Space‐Commoning Knowledge Through Urban Living Labs Across Different European Cities
(2022-08-25)
While the growing commodification of housing and public spaces in European cities is producing urban inequalities affecting mostly migrant and vulnerable populations, there are also manifold small-scale neighbourhood-based collaborative processes that seek to co-produce shared urban resources and contribute to more resilient urban developments. As part of the ProSHARE research project that investigates conditions in which sharing takes place and can be expanded to less-represented populations, we focus here on sharing ...

Effects of Mangosteen Peel Phenolic Compounds on Tilapia Skin Collagen-Based Mineralized Scaffold Properties
(2022-09-16)
A proper valorization of biological waste sources for an effective conversion into composites for tissue engineering is discussed in this study. Hence, the collagen and the phenolic compound applied in this investigation were extracted from waste sources, respectively, fish industry rejects and the peels of the mangosteen fruit. Porous scaffolds were prepared by combining both components at different compositions and mineralized at different temperatures to evaluate the modifications in the biomimetic formation of ...

Das Wohlbefinden von Kindern als elterliches Konstrukt
(2022-07-03)
Der Beitrag beschäftigt sich mit der Perspektive von Eltern auf das Wohlbefinden ihrer Kinder unter dem Eindruck der pandemiebedingten Schließungen von Kindertageseinrichtungen. Auf Basis qualitativ-rekonstruktiver Analysen kann gezeigt werden, wie sich die Wahrnehmungen der eigenen und der kindlichen Handlungsmächtigkeit bedingen. In Verbindung mit der Verfügbarkeit des Zugangs zur sog. Notbetreuung beeinflusst dieses Verhältnis das Belastungserleben.

Multi-Task Autoencoders and Transfer Learning for Day-Ahead Wind and Photovoltaic Power Forecasts
(2022-10-30)
Integrating new renewable energy resources requires robust and reliable forecasts to ensure a stable electrical grid and avoid blackouts. Sophisticated representation learning techniques, such as autoencoders, play an essential role, as they allow for the extraction of latent features to forecast the expected generated wind and photovoltaic power for the next seconds up to days. Thereby, autoencoders reduce the required training time and the time spent in manual feature engineering and often improve the forecast ...

Redoxtrons – An experimental system to study redox processes within the capillary fringe
(2023-02-02)
Spatiotemporal characterisation of the soil redox status within the capillary fringe (CF) is a challenging task. Air-filled porosities (ε), oxygen concentration (O₂) and soil redox potential (Eₕ) are interrelated soil variables within active biogeochemical domains such as the CF. We investigated the impact of water table (WT) rise and drainage in an undisturbed topsoil and subsoil sample taken from a Calcaric Gleysol for a period of 46 days. We merged 1D (Eₕ and matric potential) and 2D (O₂) systems to monitor at ...

Analysis and Validation of Varied Simulation Parameters in the Context of Thermoplastic Foams and Special Injection Molding Processes
(2023-04-28)
The simulation solutions of different plastic injection molding processes are as multifaceted as the field of injection molding itself. In this study, the simulation of a special injection molding process, which generates partially foamed integral components, was parameterized and performed. This partial and physical foaming is realized by a defined volume expansion of the mold cavity. Using the injection molding simulation software Moldex 3D, this so-called Pull and Foam process was digitally reconstructed and ...

Model selection, adaptation, and combination for transfer learning in wind and photovoltaic power forecasts
(2023-03-14)
There is recent interest in using model hubs – a collection of pre-trained models – in computer vision tasks. To employ a model hub, we first select a source model and then adapt the model for the target to compensate for differences. There still needs to be more research on model selection and adaption for renewable power forecasts. In particular, none of the related work examines different model selection and adaptation strategies for neural network architectures. Also, none of the current studies investigates the ...

High Buffering Potential of Winter Wheat Composite Cross Populations to Rapidly Changing Environmental Conditions
(2023-06-20)
A winter wheat composite cross population (CCP), created in the UK in 2001, has been grown in Germany, Hungary, and the UK since 2005 (F5 generation). In 2008/09 (F8), a cycling pattern for the populations was developed between partners to test the effects of rapidly changing environments on agronomic performance and morphological characteristics. One CCP was grown by eight partners for one year and subsequently sent to the next partner, creating “cycling CCPs” with different histories. In 2013, all eight cycling ...

Orchard meadows: consumer perception and communication of a traditional agroforestry system in Germany
(2023-03-23)
Europe has a large variety of historic cultural agroforestry systems which provide numerous ecosystem services. Traditional agroforestry landscapes are characterized by a high level of biodiversity, but they lack an economic basis due to considerable time and financial effort required for cultivation, maintenance, and harvesting. Orchard meadows (OM) are a typical example for agroforestry systems. They combine large fruit trees with undercropping or livestock raising. This study investigates consumer knowledge and ...

Anonymisierung von Patientendaten durch Fremdlabore für Dritte
(2023-05-25)
Medizinische Diagnostik findet oft in einem Netzwerk statt. Proben oder Gesundheits(roh)daten werden von Ärztinnen und Ärzten erhoben und von diesen an Fremdlabore zur Diagnostik weitergeleitet. Diese Labore bedienen sich dann oft weiterer Dienste, um Verfahren zu beschleunigen oder Ergebnisse zu verbessern (Dritte). Der Beitrag betrachtet die datenschutzrechtlichen Implikationen dieses Vorgehens aus der Perspektive eines Fallbeispiels aus der Blutbildanalyse (I.) und eines entsprechenden Systemsaufbaus zur ...
