Hybrid machine learning based on Hamiltonian formulations has recently been successfully demonstrated for simple mechanical systems, both energy conserving and not energy conserving. We introduce a pseudo-Hamiltonian formulation that is a generalization of the Hamiltonian formulation via the port...
Transformers are key components in the power system and transformer failures can cause long power outages with high costs to society. Transformer failures are rare, and each case is unique with respect to its consequences. This shapes the data and statistics we have available to predict future...
This paper presents a semi-analytical Monte Carlo method for rare event sampling applied to power system reliability analyses, which combines traditional Monte Carlo-based methods with simplifications from analytical methods. The result is a procedure which assess the reliability of a system with...
Vi bør snarest begynne å lage flydrivstoff fra norsk biomasse, som rester fra skogsdrift eller avfall. Både EUs klimamål og faren for handelskriger tilsier det....

Barriers and good practices in ambitious projects How can we ensure good processes before, during and after the realization of a zero-emission area? How can we ensure that buildings are realized as intended? Why do we struggle with good intentions being lost in the process from early planning to...
Numerical weather prediction products, radar products, and user terminal observations are used to estimate propagation conditions for the nearest hours lead time. Validation results show good correspondence between predictions and observations using beacon data and user terminal data, but with an...
Assessment of acid dew point in industrial off-gas has become increasingly important with strategies for heat recovery and the use of more concentrated gas compositions. Several approaches to acid dew point assessment make use of glassware not compatible with the high fluoride concentrations found...
Kriterier for sirkulære bygg – kartlegging av bransjestandard Det er behov for videre metodeutvikling av sirkularitet i norske bygninger, inkludert målenheter, definisjoner, systemgrenser og kartlegging av bransjestandard. Denne rapporten samler nåværende statistikk og data for å sette "dagens...
Aluminium is applied in food packaging due to its preservative capability. However, food residue and the fact that most packaging is thin gauge material, 50–250 µm, makes recycling challenging. In Northern Europe, processed cheese, caviar, and mayonnaise are popular items stored in toothpaste-shaped...
This paper presents an algorithm for feature point extraction from scanning data of large tubular T-joints (a sub-type of a TKY joint). Extracting such feature points is a vital step for robot path generation in robotic welding. Therefore, fast and reliable feature point extraction is necessary for...
