Energy Measurement of Electric Fence

, 2011
Syftet med denna rapport är att få en inblick hur elstängselaggregat fungerar och hur energimängden, från en stöt, noterar. Det har då tagits fram en förstudie om vilka elstängselaggregat och vilka mätinstrument som ska användas. Mätningar har gjorts både i laborationsmiljö och ute i jordbruksmiljö. En enklare funktion och uppbyggnad har undersökts och

Field Report from Collaborative Research Center 1625: Heterogeneous Research Data Management Using Ontology Representations

Advanced Engineering Materials, EarlyView.
A unified research data management framework for heterogeneous materials data is presented. The system integrates multimodal datasets using ontologies and knowledge graphs, enabling interoperability and FAIR (findable, accessible, interoperable, reusable) data principles. By linking data across scales and workflows, it supports reproducible, Artifitial
