Recycled polypropylene fibre-reinforced concrete: from recyclability and recoverability to materials and application
(English) In recent decades, fibre-reinforced concrete (FRC) has played a significant role in construction due to its enhanced residual flexural tensile strength in comparison to plain concrete. However, with the increasing ...
Urban freight distribution management and pricing with tradable mobility credits
(English) Cities around the world are still facing increasing congestion problems. Emerging demands of ecommerce and other commercial activities make this situation worse. Congestion pricing schemes gain low public acceptance ...
Simple coherent technologies for next-generation edge optical networks
(English) Optical fiber communications have revolutionized the telecommunications networks in all segments, leveraging a wide set of advantages ranging from THz capacity to low-loss, security and form factor. In long-haul ...
Grid-forming strategies for renewable energy sources
(English) Modern power systems are increasingly integrating a larger share of renewable energy resources to mitigate climate change. These renewable resources are gradually replacing conventional power plants, which employ ...
Additive manufacturing of WC-CO cemented carbides: microstructural, lenght-scale and layer assemblage orientation effects on hardness, sliding contact response and fracture behaviour
(English) This PhD thesis explores the microstructure–mechanical property relationships of WC-Co cemented carbides (hardmetals) produced using two sinter-based additive manufacturing (AM) techniques: Binder Jetting Technology ...
The effect of social interactions on collective behavior: from flocking to opinion polarization
(English) Like viruses, information, knowledge, and emotions disseminate through a population, and the social interactions between individuals can give rise to a rich tapestry of collective behavior. Usually, we are able ...
Towards generalisable fault detection in smart buildings: hybrid modelling, calibration, and transfer learning strategies
(English) The building sector represents a significant portion of global energy consumption, accounting for over one-third of the total energy used worldwide. Within this sector, Heating, Ventilation, and Air Conditioning ...
