Transition zones in railway tracks, which occur at changes in track form and or substructure properties, are known to cause issues with track degradation. Examples can be found where a track section, usually a ballast track, transits to a slab track to cross a roadway or waterway through supporting structures such as bridges, level crossings,...

Coggins, T.N. (author)
In the introduction of this thesis, I contend that robot ethics, as a research field, generally treats privacy as the appropriate distribution of information, and therefore overlooks privacy concerns raised by robots beyond this conceptualization’s purview. I illustrate this contention by evaluating a hypothetical case involving a household...

The hospitality industry, struggling with significant staff shortages, has increasingly turned to service robots as a solution. However, the prevalent service robot’s design with anthropomorphic appearance is considered inharmonious with the fine-dining restaurant ambiance and may harm the guests’ perception of the service. An alternative...

To reduce global warming the emission of greenhouse gases (GHG) must be net zero in 2050, Paris agreement. In the Netherlands the building sector is responsible for 38% of total GHG emissions, 27% being operational carbon (related to energy use) and 11% embodied carbon (related to the use of materials). A large portion of the GHG emissions in...
