Standard Newton methods that are used to advance fully implicit or adaptive implicit schemes in time often suffer from slow or stagnant convergence when natural initial guesses are too far from the solution or the discrete flow equations contain nonlinearities that are unbalanced in time and space...
Network models have proved to be an efficient tool for building data-driven proxy models that match observed production data or reduced-order models that match simulated data. A particularly versatile approach is to construct the network topology so that it mimics the intercell connection in a...
Façade claddings with open joints are commonly used in large buildings in Norway. Plane façade panels of fibre cement and high-pressure laminate boards are usually fabricated using joint width of 5 – 10 mm, while solar panel claddings may have joints up to 20 mm. Vertical joints are relatively...
Remotely measuring subsurface water currents from imagery of the wave field has become a much-used technique. We study the biases and errors in such measurements due to spectral leakage and suggest mitigating procedures. Deviations between peak values in the 3-D wave spectrum and the known...
For improved control of biomaterial property design, a better understanding of complex coacervation involving anionic polysaccharides and proteins is needed. Here, we address the initial steps in condensate formation of β-lactoglobulin A (β-LgA) with nine defined alginate oligosaccharides (AOSs) and...
Accurate estimation of the wave field and subsequent vessel response prediction are vital for making crucial judgments on the safe and timely execution of marine operations. Decision support systems based on the Response-Based Decision-Making (RBDM) methodology are still in the early stages due to...
To achieve climate neutrality in the food sector, there is an urgent need for eco-friendly steam boilers. The absorption-compression heat pumps (ACHP) using an ammonia-water mixture as working fluid can provide a high heat sink temperature at low discharge pressure levels and with temperature glides...
Dairy processing is considered very energy-intensive due to significant thermal demands for both cooling and heating at different temperature levels. Conventional dairy plants have separate systems for supplying the various thermal loads, such as refrigeration systems for the cold side of the...
Refrigeration systems onboard fishing vessels are necessary to keep the catch at a low temperature and to ensure long shelf life. Most refrigeration systems in the world fishing fleet still have R-22 as a working fluid, which has both ozone depleting potential and global warming potential. In...
Crude oils are among the world’s most complex organic mixtures containing a large number of unique components and many analytical techniques lack resolving power to characterize. Fourier transform ion cyclotron resonance mass spectrometry offers a high mass accuracy, making a detailed analysis of...
Fuels supplied 76% of global final energy consumption in 2021. Although ongoing electrification efforts can significantly reduce this dominant share, fuels will continue to play a leading role in the global energy system. Hydrogen is the most studied candidate for decarbonizing fuels, but storage...
DAC deployment is still an open question. Recent publications focused on energy consumption and the relationship between the cost of captured CO2 and operating conditions. These works addressed a preliminary assessment of the best locations but neglected the importance of the local context to...
A series of AB6 type-7 miktoarm star copolymers consisting of poly(ethylene glycol) (PEG) as the A arm and poly(ε-caprolactone) (PCL) as the B arm are synthesized by controlled ring-opening polymerization of the ε-caprolactone monomer. The chemical structure is confirmed and characterized by nuclear...
In situ-grown copper phthalocyanine (nCuPc) nanorod structures with nano titanium nitride (TiN_nCuPc) hybrid composites were acquired via hydrothermal conditions. As-synthesized TiN_nCuPc composites were physicochemically characterized using various spectroscopic techniques such as UV–vis, Fourier...
