This report provides an overview of methods and concepts in operational research applied to autonomy in small ports. A literature review has been conducted and is presented, along with suggestions for methods and concepts that could enhance autonomy in these ports. The report lays the foundation...

High-temperature (HT) geothermal wells can provide green power 24 hours a day, 7 days a week. Under harsh environmental and operational conditions, the long-term durability requirements of such wells require special cementitious composites for well construction. This paper reports a comprehensive...

This paper introduces a method for incorporating long-term storage into the multi-horizon modelling paradigm, thereby expanding the scope of problems that this approach can address. The implementation presented here is based on the HyOpt optimization model, but the underlying concepts are designed...

Turquoise hydrogen from natural gas pyrolysis has recently emerged as a promising alternative for low-carbon hydrogen production with a high-value pure carbon by-product. However, the implications of this technology on the broader energy system are not well understood at present. To close this...

The recent world crisis caused by the rapid spreading of the COVID-19 variants elicited how urgent it is to develop a robust and reliable epidemiological model for effective policy decision-making. The aim of this paper is to investigate the impact of con-trol measures, e.g. face mask use, on the...

In recent years, the field of neural fields has seen a significant surge in interest, particularly following the introduction of Neural Radiance Fields (NeRFs), which benefitted from the advancements in sinusoidal activation functions. This new implicit representation, offered by neural fields...

The design of a neighbourhood has a major influence on the health of the people living there. Researchers in the Building Health project are investigating how environments can be designed to promote the health of local residents, which could then reduce the strain on health and care services, as...

Nickel silicides (NiSi) are renowned for their ability to withstand high temperatures and resist oxidation and corrosion in challenging environments. As a result, these alloys have garnered interest for potential applications in turbine blades and underwater settings. However, their high brittleness...

Functional materials such as nickel silicides (Ni3Si) are considered promising materials for building complex and strong structures. They have proven to have a high melting point, low electronic resistivity, excellent corrosion resistance, and thermally stability, however, their overall performances...

The detrimental effects induced by hydrogen on different materials—including steels—are a well-known and studied phenomenon. In the last century, several research papers focusing on hydrogen damages were published, including investigations concerning the hydrogen impact on the crack growth rate in...

The process operating performance assessment (POPA) of froth flotation under multimode is an important means to improve production efficiency and product quality. In the plant, froth flotation presents multimode characteristics due to the uncontrollable of the objective conditions of production. In...

Articular cartilage regeneration is a challenge in tissue engineering. Although diverse materials have been developed for this purpose, cartilage regeneration remains suboptimal. The integration of nanomaterials into 3D network materials holds great potential in the improvement of key mechanical...

Manganese- and nitrogen-doped carbon materials were produced using NaOH-activated wood char and wood-processing residues such as wood chips and black liquor and evaluated as oxygen reduction catalysts for further application in fuel cells or metal–air batteries. The elemental and chemical...

This work is dedicated to developing a laboratory method for assessing emissions of polycyclic aromatic hydrocarbons (PAHs) from different carbon-based materials at elevated temperatures. The method will additionally contribute to enhancing the fundamental knowledge about the formation and...

The susceptibility of pipeline steels to hydrogen embrittlement, which can significantly impair mechanical performance, especially fracture toughness, is a critical issue in infrastructure integrity. This study evaluates the fracture toughness of modern and vintage API X65 steels under cathodic...
