Rongen, S. (author), Nikolova, N. (author), van der Pas, M. (author)Industry 4.0 has proposed the Asset Administration Shell (AAS) model for digital twins. This model should help to solve interoperability issues, a topic that is also addressed by the Semantic Web and its Resource Description Framework (RDF). AAS and RDF-based models have their own strengths. AAS models are easier to integrate with operational...article 2023

Elahi, H. (author), Geilen, M. (author), Basten, T. (author)Streaming systems are naturally modeled with synchronous dataflow graphs (SDFGs). The max-plus semantics of an SDFG is a compact matrix representation of its timing behavior. The max-plus semantics enables us to analyze and control timing properties of the systems, such as the obtainable minimum guaranteed throughput and maximum latency....article 2023

(author)In the last 15 years semantic 3D city models have seen a steady growth in terms of creation and adoption. Many cities world-wide have now at least one city model which can be used for several applications. Energy- and sustainability-related topics are among those that have experienced a noteworthy increase of interest from the Geomatics...conference paper 2022

M. Sanchez, M. (author), Pogosov, D. (author), Silvas, E. (author), Mocanu, D.C. (author), Elfring, J. (author), van de Molengraft, R. (author)An automated vehicle (AV) must always have a correct representation of the drivable space to position itself accurately and operate safely. To determine the drivable space, current research focuses on single sources of information, either using pre-computed high-definition maps, or mapping the environment online with sensors such as LiDARs or...article 2022

Frommholz, D. (author), Kuijper, F. (author), Bulatov, D. (author), Cheung, D. (author)This paper discusses a rapid workflow for the automated generation of geospecific terrain databases for military simulation environments. Starting from photogrammetric data products of an oblique aerial camera, the process comprises deterministic terrain extraction from digital surface models and semantic building reconstruction from 3D point...conference paper 2022

Bouter, C. (author), Kruiger, H. (author), Verhoosel, J.P.C. (author)Data pre-processing, analysis, and quality checks are constantly tailored to a specific data set. Ontology Based Data Access (OBDA) can provide the interoperability layer to apply the same procedure on heterogeneous data sets. The SOSA ontology, for example, provides a domain-independent generalization of sensor measurements, and is already...conference paper 2021

Sijs, J. (author), Fletcher, J. (author)Robotic systems operating in the real world would benefit from a clear semantic model to understand the real world. Such semantics are typically captured in a knowledge structure. The speed at which robots need to update their real-world knowledge (because of new sensory observations) prevented the use of complex knowledge structures, due to...conference paper 2021

They require improved data control capabilities that prevent their shared data from being misused. Currently, such capabilities are typically realized as situation-specific closed ecosystem solutions in a 'hub-model' approach. This...conference paper 2020

Mohammadi, M. (author), Atashin, A.A. (author), Hofman, W. (author), Tan, Y. (author)Ontology alignment is widely used to find the correspondences between different ontologies in diverse fields. After discovering the alignments, several performance scores are available to evaluate them. The scores typically require the identified alignment and a reference containing the underlying actual correspondences of the given ontologies....article 2018
