Self-consistent quasiparticle GW (sc-QPGW) calculations are used to calculate the electronic properties of α-Si3N4 and β-Si3N4, as well as α-SiO2 (quartz). The optical properties are evaluated by solving the Bethe-Salpeter equation in the Tamm-Dancoff approximation. For quartz, the predicted dielectric...

...general, and within methods for action-refinement in particular. In this paper we focus on Event-B, a more recent method for action refinement. The STAIRS method belongs to another tradition. It originates from the UML community and is designed to provide an understanding of refinement and fulfillment...

...ambient assisted living (AAL), and provides elderly safety, autonomy, independence and mobility. The aim is to generate knowledge on usage, usability and technical requirements to harvest the potential benefits of using wearable and mobile technologies in care for safe and active living. The study is based...

...latest research, development and testing of robotics (incl. drone) technologies relevant for renewable energy plants. To this end, we will summarize the main areas of use for robotics and overall business cases with focus on inspection and maintenance of infrastructure, and present new results on task/mission...

...shapes, polymer types and chemical compositions. Owing to their potential for biological uptake, small microplastic particles (sMP; <100 μm) and nanoplastics (NPs) are considered to be a potential risk to organisms. Understanding how sMPs and NPs behave in the environment, and how environmental matrices...

...affine equivalence of these surfaces, and therefore, in particular, the symmetries of a surface of translation or a minimal surface of the considered types. Additionally, we apply our results to designing surfaces of translation and minimal surfaces with symmetries, and to computing the symmetries of the...

...struggling to find good and attractive housing for new residents and this has implications for rural development (Kommunal- og regionaldepartementet, 2013). Stokkøya, Frøya and Hitra Islands are examples of communities, where economic development based on natural resources and aquaculture, is offering...
