Feedback und formative Assessments in der Mathematikvorlesung

open access: yesZeitschrift für Hochschulentwicklung, 2014
Mathematische Kompetenz beinhaltet neben der Anwendung auch das Verständnis der mathematischen Konzepte. Dies wird in traditionellen Mathematikveranstaltungen für Ingenieurinnen und Ingenieure häufig nicht ausreichend gefördert und gefordert.

Buckling resistance and residual stresses of welded HSS box columns

open access: yesSteel Construction, Volume 19, Issue 1, Page 37-49, February 2026.
Abstract Welded box columns made of high‐strength steels (HSS) are characterized by high buckling resistance and low self‐weight. The residual stresses introduced by the welding process are of particular importance. In the area of the weld seams, the cooling process creates residual tensile stresses that are in equilibrium with the compression stresses

Numerical Modeling Rolling Contact Problem and Elasticity Deformation of Rolling Die under Hot Milling

open access: yesMetals, 2019
In metalworking, rolling is a metal-forming process in which slab is passed through one or more pairs of the rolling dies to reduce the thickness and to make the thickness uniform. Modeling of rolling die contact with the slab primarily needs to describe

Overcoming Thickness–Durability Trade‐Off in PEM Fuel Cells via Stretched PTFE Nanofiber‐Reinforced Composite Membranes

open access: yesAdvanced Energy Materials, Volume 16, Issue 4, 28 January 2026.
By combining emulsification electrospinning with a precision thermomechanical biaxial stretching process, ultrathin 3‐fold stretched polytetrafluoroethylene nanofiber (3‐sPTFE NF) reinforcements are developed that enable the fabrication of highly durable and high‐performing reinforced composite membranes (RCMs).

A Generalized Concept for Clustering Capabilities of Weeding Robots

open access: yesJournal of Field Robotics, Volume 43, Issue 1, Page 49-62, January 2026.
ABSTRACT Agriculture is undergoing a significant transformation process with the help of robots. Weeding robots have made their way into the market, and they play a crucial role in automating the weeding process in the field. This study introduces a generalized concept of autonomy levels for currently available weeding robots in the field as well as a ...

Mechanical Recycling of Silicone Rubber: Influence of Particle Size and Quantity

open access: yesPolymer Engineering &Science, Volume 65, Issue 11, Page 6207-6216, November 2025.
Silicone rubbers of three different hardnesses were ground into particles and used as fillers in a liquid silicone rubber matrix, whereby the particle size and quantity varied. The mechanical properties were only slightly altered by the addition of ground particles and showed the general possibility of mechanical silicone recycling.
