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 ...

Influence of blend proportion and baking conditions on the quality attributes of wheat, orange‑fleshed sweet potato and pumpkin composite flour dough and bread: optimization of processing factors
(2023-02-16)
Orange-fleshed sweet potato (OFSP) and pumpkin fruit are underutilized crops with great potential for the production of high-quality bread with health-enhancing properties. However, the incorporation of nonconventional flour in bread formula may influence the dough and bread quality properties. This study investigated the effect of partial substitution of wheat flour with OFSP (10–50%) and pumpkin flour (10–40%), baking temperature (150–200 °C) and baking time (15–25 min) on the quality properties of the composite ...

Spatial patterns of urbanising landscapes in the North Indian Punjab show features predicted by fractal theory
(2022-02-02)
Understanding and governing human settlement patterns is a major challenge of the urban age. While rural settlements emerge as parts of agricultural landscapes, cities typically evolve in economically strategic locations, and over time form hierarchical systems of cities. Purposeful planning and the collective, self-organized behavior of the inhabitants interact in the development of regional settlement patterns. Since self-organizing systems often produce fractal patterns in nature, this study combines approaches ...

Experimental and numerical polarization analysis of the 3D transfer behavior in microsphere-assisted interferometry for 1D phase gratings
(2023-06-08)
Enhancing the lateral resolution in optical microscopy and interferometry is of great interest in recent research. In order to laterally resolve structures including feature dimensions below the Abbe resolution limit, microspheres in the optical near-field of the specimen are shown to locally improve the resolution of the imaging system. Experimental and simulated results following this approach are obtained by a high NA Linnik interferometer and analyzed in this contribution. They show the reconstructed surface of ...

Microbial biomass activity of a sodic Lixisol reclaimed with gypsum and clean water irrigation in urban vegetable systems of Burkina Faso
(2023-02-13)
Background: Little is known about the effects of gypsum application to remediate saline-sodic soils in the tropics and the role of microbial indicators in soil reclamation. Aims: Our study aimed at (1) remediating a highly weathered, irrigated sodic Lixisol under prolonged urban crop production by clean water and gypsum application and (2) to determine the remediation effects on soil microbial indices. Methods: A three-factorial on-farm experiment with maize (Zea mays L.) was used to study effects on soil microbial ...

“Reconstructionism”: A Strategy to Improve Outdated Attempts of Modernist Post‐War Planning?
(2023-02-23)
Recently, Germany has seen a series of inner‐city projects that tend to reconstruct pre‐war buildings or ensembles lost in the Second World War after demolishing earlier attempts to redefine the place in which they had been located with the means of modernist architecture. While those modernist buildings are often seen as “eyesores” by ordinary citizens advocating their demolition, the newer reconstructionist projects are criticized heavily by architects and planners not only because they often bring along revisionist ...
