Relatively high concentrations of oxygen vacancies and effects on thermoelectric properties have been reported in the literature on state-of-the-art thermoelectric sodium cobaltates. However, first principle calculations suggest high energies and low concentrations of such vacancies. Experiments in our...
The report describes the different types of weather and road information systems in Finland, Denmark, Sweden, Iceland, Austria, Germany, Canada and USA...
The physical properties and the behaviour of the refractory lining in Al-electrolysis cells as well in anode baking furnaces are crucial for both economic and environmental aspects of the Al production. This course will give an introduction to the physical and thermal properties of materials used in...
...aims to unveil what requirements the introduction of Connected and Automated Vehicles (CAVs) will have for the Physical and Digital Road Infrastructure (PDI) on public roads. The study is based on a literature review of reports from research and innovation projects combined with literature from academic...
Stainless steel bipolar plates (BPP) for polymer electrolyte membrane fuel cells (PEMFCs) have good manufacturability, durability and low costs, but inadequate corrosion resistance and elevated interfacial contact resistance (ICR) in the fuel cell environment. Thin film coatings of titanium nitride (TiN) of...
This article proposes a framework for the integration of tactical and operational optimisation models for maintenance scheduling and routing at offshore windfarms. A tactical model is formulated to find the optimal schedule for preventive maintenance over a medium-term planning horizon (one month). The...
...reinforced epoxy-mica samples including void enclosure with diameter of 10 mm. The PD-activity was examined at test frequencies from 0.1 Hz to 300 Hz, and the temperature was varied in the range from 20°C to 90°C. The PD inception voltage was found to be frequency independent, while the maximum apparent...
