Development of deep-placement fertiliser applicator and modelling of loads arising in the process of its operation
(2023-12-28)
The article considers the method of minimum tillage, namely soil tillage, loosening the soil, and fertiliser application at a depth below the level of the main crop. This method allows you to minimize the number of operations used in the cultivation of row crops such as soybeans, wheat, and others. The research in the area of soil tillage, namely the mathematical calculation and static analysis performed with the CAD system, revealed the loads that appear directly in the places where the soil deepener is attached to ...

Parameter identification for constitutive models of innovative textile composite materials using digital image correlation
(2019-11-18)
This contribution focuses on an innovative composite material consisting of textile layers made from continuous wooden fibers embedded in a thermoplastic matrix. A finite element simulation of potential use‐cases is planned to support the development process and to study the suitability of the material in an architectural context. The simulation is based on a constitutive model assuming homogenous orthotropic elastic behavior and will be expanded to include multiscale modeling in future research. The material parameters ...

Reporting Power
(2024)
An eclectic genealogy (Foucault, 1977) that reconstructs the previous understanding and emergence of a ‘taken for granted’ global practice: the practice of suspicious activity reporting. A governance practice whereby financial institutions worldwide document and report the conduct of consumers deemed suspicious. At the center of this practice is a material artefact, a multipage fillable form called the Suspicious Activity Report. Following Actor-Network Theory (Latour, 1987), the form also serves as the centerpiece ...

Influence of deep rolling at different temperatures on near-surface and mechanical properties of a Maraging C250 steel
(2024-04-27)
Due to an outstanding combination of high strength and fracture toughness Maraging steels are used in numerous industries, e.g., in the aerospace sector. The high strength can be attributed to precipitation strengthening by conventional age-hardening heat treatments. However, as many of the envisaged applications will suffer from cyclic loadings, the fatigue properties are of significant interest in terms of a reliable use. Generally, Maraging steels are characterized by a relatively low fatigue strength limiting the ...

Dynamics of Norms in Decision-Making
(2024-01)
So far, there is a lack of understanding how norms change. The aim of the present dissertation was twofold: (1) addressing differences between change processes of different types of norms and (2) focusing more particularly on how norms are internalized. To study norm dynamics, a multi-method approach was chosen, combining theory, social simulation, and experimental research. In the theoretical contribution, a psychologically grounded conceptual model of norm change and decision-making was presented. Based on a refined ...

Working Paper: Modeling Infection Risk in Local Public Transport
(2024)
To model the infection risk in local public transport, additional information on the personal contacts during a trip with local public transport as well as the contact duration with them is necessary. As morning student traffic in local public transport vehicles was assumed to hold a high infection risk during the COVID-19 pandemic, staggered school starting times were tested in the city of Herne in Germany. The data obtained during this time was used to create a calculation tool for the number of personal contacts ...
