Clean Energy and Energy Efficiency
Thermal science, 2018 Sustainable development is, by any definition, in the focus of interest in the 21st century, as it is a matter of the survival of mankind. One has to keep in mind, that global population is currently about 7.6 billion, whilst a century it was less than 2.0 billion ; furthermore, more than three quarter of the world’s population is living in cities ...

A Knowledge‐Based Approach for Understanding and Managing Additive Manufacturing Data
Advanced Engineering Materials, EarlyView.Additive manufacturing processes generate a large amount of data. Effectively managing, understanding, and retrieving information from this data remains a major challenge. Therefore, we propose an ontology‐based approach to integrate heterogeneous data, enable semantic queries, and support decision‐making.
