Due to the growing impact of digital platforms, it is increasingly important to understand their evolution through mathematical models. As their value is dependent on their user base, we present an improved perspective on modeling the number of users. Modeling digital platforms is frequently...
Flexible manufacturing systems in high-mix low-volume segments offer many challenges in terms of planning and scheduling. The complexity of these systems often requires a systemic approach for which humans are the perfect actors. However, computer systems can support scheduling tasks more...
Introduction and aims: During an Endovascular Aneurysm Repair (EVAR) procedure a stiff guidewire is inserted from the iliac arteries. This induces significant deformations on the vasculature, thus, affecting the pre-operative planning, and the accuracy of image fusion. The aim of the present work is...
Trawl codends are commonly made of diamond-mesh netting. However, diamond-mesh codends vary in mesh geometry along its length and during fishing due to catch build up. This introduces variability in the size selection process. This phenomenon compromises the rationality of regulating exploitation...
Water supply and drainage systems, which are categorized as critical infrastructure, serve a crucial role in preserving societal health and well-being. Since climate change effects, harsher regulations, population changes, and aging infrastructure pose problems for these systems, the industry is...
In this report we co-produced a matrix of governance fragmentation in the Norwegian plastic value chain to assess where there are overlaps, interplay and synergies to be aligned. This also included an assessment of the global level of plastic regulatory fragmentation as it relates to the upcoming...
Traditional lean tools such as value stream mapping (VSM) do not account for environmental benefits. Simultaneously, life cycle assessment (LCA) does not account for improving manufacturing performance. Given the advent of the concept of sustainable development as an approach to fulfill the needs of...
This paper investigates the impact of social media utilization on problem-solving routines in organizations undergoing Lean Production (LP) implementation. A multi-case study was conducted in three firms from different sectors with distinct maturity levels of LP implementation. Empirical evidence...
Advances in manufacturing technology made plastics comparatively inexpensive, light, mouldable and durable. The great success of plastics comes along with a strong negative environmental impact and their accumulation in landfills and leakage into the natural environment is now recognized as a global...
Aerospace AA2xxx and AA7xxx alloys have good mechanical properties such as high strength-to-weight ratio, fatigue- and corrosion resistance. These alloys are known for poor weldability with traditional fusion welding techniques due to hot cracking sensitivity and large heat affected zone with...
Lightweight solutions will become increasingly necessary for the next generation of passenger cars. Applications of age-hardenable high strength aluminium material can be superior to traditional low strength alloys, especially if the processing of the parts itself is cost effective. Sheet forming of...
The reduction behavior of pelletized and pre-oxidized ilmenite is investigated in H2-H2O atmospheres containing between 0 and 7% H2O and at temperatures between 983 and 1183 K (710 and 910 °C). The reduction mechanism occurs in two stages wherein the rapid reduction of trivalent to divalent iron...
Carbon has been deposited on HCFeMn slag from methane-containing gas with and without CO2, creating C-MnO composites and giving a hydrogen-rich off-gas as a by-product. The maximum deposited amount corresponds to 38 ± 6% of the carbon required for reduction of all manganese in the slag to metallic...
The choice of ground gear design in demersal trawls can significantly affect both catch composition and efficiency. The preference for a specific design depends on the fishing ground. In the North-Eastern Mediterranean, two types of ground gears, Single Line and Double Line are commonly used...
The mechanical response of dual phase (DP) steel exhibits a complex dependence on the microstructure. The chemical composition and microstructure characteristics of the phases have significant effects on the contrast between the response of the phases, which affects, not only the strength and...
