Accurate estimation of catch is essential for sustainable fisheries. It ensures precise catch reporting, provides a better basis for stock assessment, and helps prevent overfishing. With recent advances in deep learning, this could be solved using computer vision, however, collecting and annotating...

Density functional theory and micromechanical methods were used to investigate the adsorption and decomposition of formaldehyde on the surfaces of pure and Mn-doped Fe3O4 catalysts. The O₂ site was determined as the optimal adsorption site, and single doping with Mn promotes the generation of oxygen...

This study investigates AC electrical aging induced by partial discharge (PD) in fluoropolymer cable insulation materials, namely fluorinated ethylene propylene (FEP) and perfluoroalkoxy (PFA), with the cross-linked polyethylene (XLPE) serving as the reference material. Utilizing a specialized...

The presence of power electronics converters has become more and more dominant in power systems and this is posing stricter requirements for their controls in terms of stability and performance. The class of Model Predictive Controls (MPC) is particularly well suited for power electronics converters...

The need of efficient electric transmission systems, the rise of renewable energy production, and the development of battery storage systems have driven the adoption of Modular Multilevel Converters (MMC), which offer better performance than conventional converters. However, the diagnosis of...

Coal properties are important factors affecting the coal pyrolysis heat absorption. In this work, thermogravimetric-differential scanning calorimetry (TG-DSC) method was used to measure the pyrolysis heat absorption of 20 coal samples with different degrees of coalification, including anthracites...

Wood stoves are commonly used for the space heating of residential buildings, especially in Norway. While their influence on building energy consumption has been extensively studied, the contribution of wood stoves to building power consumption has barely been addressed in the scientific literature...

This work has been carried out to demonstrate the effect of water-leachable biomass components on the liquid product distribution of torrefaction. For the partial removal of the mineral matter, each biomass feedstock was leached with hot water. The original and leached wheat straw, rape straw and...

Capturing CO₂ from waste to energy plants has attracted increasing interest, particularly for the goal of achieving negative emissions. Oxy-combustion is a competitive alternative technology for CO₂ capture. The main challenge is that oxygen production is expensive. In addition, a subsequent...

This paper computationally investigates partial discharges (PDs) in the form of self-sustained gas discharges. It presents two methods for predictive modeling: (1) a new low-fidelity algorithm for the PD inception voltage is introduced. The method is volume-resolved and describes both the strength...

Full electric vessels can benefit from hybrid energy storage systems (HESS) that combine two storage technologies of different characteristics in terms of power and energy density. The optimal design of a HESS for a vessel is generally a rather complex multivariable optimization with several degrees...

CO₂ capture from industrial clusters and multi-source industrial sites can reduce costs and facilitate large-scale implementation through shared infrastructure. However, since multiple clustering strategies are possible, a key question arises: when and how should CO₂ capture be clustered? While...

In Europe, most of the CO₂ that needs to be captured is expected to be stored offshore due to the lack of social acceptability for onshore CO₂ storage. This means that in the coming decades, infrastructure to transport several hundred million tonnes of CO₂ from coastal locations to offshore storage...
