Prerequisite Relations Annotation Tool: Annotation and analysis of educational relations in texts

open access: yesJournal of the Association for Information Science and Technology, EarlyView.
Abstract Relations between terms in texts have long been studied in linguistics and specialized knowledge domains, especially when occurring in educational materials like textbooks, where they play a crucial role in guiding instructional design and learning.

Simulation Model for Digital Twins of Pneumatic Vacuum Ejectors

open access: yesChemical Engineering &Technology, Volume 46, Issue 1, Page 71-79, January 2023., 2023
A novel concept for modeling and simulating the fluidic behavior of pneumatic vacuum ejectors as key components of vacuum handling systems is proposed. To increase the simulation accuracy, the concept can access instance‐specific data instead of object‐specific data.

Kinetic Control of Threading and Dethreading in Linked Rotaxanes via Hydrogen Bonding

open access: yesChemistry – An Asian Journal, Accepted Article.
The kinetic control of macrocyclic motions is a key aspect of mechanically interlocked molecules (MIMs). Although hydrogen bonding (H‐bonding) offers a high reversibility and selectivity, the use of neutral H‐bonding to control the macrocyclic mobility remains limited. In this study, the effects of H‐bonding on the threading and dethreading kinetics of

Dynamic Friction Model for the Investigation of Stick‐Slip Oscillations

open access: yesChemical Engineering &Technology, Volume 46, Issue 1, Page 29-36, January 2023., 2023
An efficient dynamic friction model based on the Stribeck curve is presented, which allows to investigate the influencing parameters on the stick‐slip effect through finite element simulations. The simulation of a tribometer test proofs that the model correlates well with the tribometer test results.
