Oil demand: dependence or flexibility?

open access: yes, 2016
Iraq’s invasion of Kuwait, the boycott of Iraqi and Kuwaiti oil and the consequent surge of international oil prices mark the third major disruption on the oil market in the past two decades. The export reductions provoked by the Arab-Israeli war of 1973, the Iranian revolution of 1978-79 and the present Gulf crisis are very similar – amounting in each

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

open access: yesAdvanced 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
